Start dialer.exe from browser?

I am actually around the internet development for quite a while now - but I never had to do the following and have no idea how to solve it:
Our computers have connected Telephones which are used with the Dialer.exe.
As I am working on an internal Clientdatabase in our network I would like to support the feature of clicking a "link" == telephonnumber in the browser in our database -> that click should execute the following task : open dialer.exe on users C:// , paste in telephonenumber in numberfield.
Thank you for your help.

That should be possible by adapting a Costum-URI-Sheme to your needs. See here:
https://msdn.microsoft.com/en-us/library/aa767914%28v=vs.85%29.aspx
Problematic is that this solution is yet Windows only and that you need to set registry-entries on every machine. Probably those values are applicable with an appropriate infrastructure but if there's not domain existent this could be a horrendous amount of work...
Edit:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\telephone]
#="URL:Telephone Dialer"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\telephone\DefaultIcon]
#="\"C:\\Windows\\System32\\dialer.exe\",1"
[HKEY_CLASSES_ROOT\telephone\shell]
"URL Protocol"=""
[HKEY_CLASSES_ROOT\telephone\shell\open]
[HKEY_CLASSES_ROOT\telephone\shell\open\command]
#="\"C:\\Windows\\System32\\dialer.exe\" \"%1\""

HTML transient modal window

We have a legacy web application. At various places it opens a window with the help of Privilege Manager on Firefox to get the needed result.
Some of these windows open a Java applet or a PDF document.
The client machines are updating Firefox and Privilege Manager is gone.
What is the easiest way around it?
The problems are :
There must be only one instance of the pop-up at anyone time. This could be done by selecting appropriate window name on window.open() call.
If the window is opened again (by means of user action), it should not reload but just focus to bring it to the foreground (I have seen I can keep a reference to the window on JavaScript to do that)
It basically really must be transient/modal so that the client cannot leave the current page or reload or any other kind of interaction with the parent window (except opening/refocusing the child window) without closing the child window first. I have no idea how to do that.
Do anyone has an idea how to do that?
The client is only Firefox (it works in a special kiosk configuration) on Linux.
I read somewhere that I could somehow write an extension but I am basically clueless about extensions and its API.
Edit1:
Example of (simplified) legacy code. Not really sure if all the permissions were required, but this is it: This function opens a window that stays over the parent window and prevents any interaction from the user with the parent window.
function fWindowOpen(url, name) {
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
netscape.security.PrivilegeManager
.enablePrivilege("CapabilityPreferencesAccess");
netscape.security.PrivilegeManager
.enablePrivilege("UniversalPreferencesWrite");
netscape.security.PrivilegeManager
.enablePrivilege("UniversalPreferencesRead");
netscape.security.PrivilegeManager.enablePrivilege("UniversalFileRead");
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
window.open(
url,
name,
"screenX=70,dependent=yes,menubar=0,toolbar=0,width=900,height=700,modal=1,dialog=1"
);
}
function fnCapture(){
fWindowOpen("/path/to/document_or_japplet/page","_blank");
}
HTML:
<button value="Capture" property="btnCapture" onclick="javascript:fnCapture();"/>
Edit2: Solution
On a typical extension, on the xul code, define this javascript code:
var dialogExt = {
listener: function(evt) {
// Do work with parameters read through evt.target.getAttribute("attribute_name")
window.openDialog(evt.target.getAttribute("url"), evt.target.getAttribute("name"), evt.target.getAttribute("features"));
}
}
// from examples
document.addEventListener("dialogExtEvent", function(e){ dialogExt.listener(e); }, false, true);
Then, on the web page:
var element = document.createElement("dialogExtElement");
element.setAttribute("url", url);
element.setAttribute("name", name);
element.setAttribute("features", features);
document.documentElement.appendChild(element);
var evt = document.createEvent("Events");
evt.initEvent("dialogExtEvent", true, false);
element.dispatchEvent(evt);
Now, maybe I am missing some security checks to let the code work if it originates from the same host, and how to handle a reference to the document that requested the dialog as means of interaction between the dialog window and it's opener.

The Privilege Manager was deprecated in Firefox 12 and removed in Firefox 17 (briefly restored).
You might want to look into Window.showModalDialog(). However, it is deprecated and is expected to go away within the year, or in 2016 if you go with an extended service release (ESR) of Firefox 38. It may be a temporary solution while you develop an extension.
In order to accomplish the same tasks, you will need to write an extension and ask the user to install it (from Bypassing Security Restrictions and Signing Code, the old information about Privilege Manager):
Sites that require additional permissions should now ask Firefox users to install an extension, which can interact with non-privileged pages if needed.
It is possible to write such an extension using any of the three different extension types:
XUL overlay
Restartless/Bootstrap
Add-on SDK
For the first two types, you would use window.open(). The modal option is in "Features requiring privileges". You will probably also want to look at Window.openDialog().
For the Add-on SDK, you would normally use the open() function in the SDK's window/utils module. Here, again, you will probably want to look at openDialog().
It appears you may be opening content that is supplied from the web in these modal windows. It is unlikely that you will get an extension approved to be hosted on AMO which opens content in such windows which in not included in the add-on release. This does not mean you can not develop the extension and have it installed on your kiosk clients without hosting it on AMO. However, there are additional restrictions in development for Firefox this year which will make this significantly more difficult, see: "Introducing Extension Signing: A Safer Add-on Experience".

You should be able to get similiar window.open behavior, including support for the modal option from the sdk's window/utils module.
You will have to install the onclick listener with a content script, send a message to the addon-main through its port and then open that window from the addon main.

Grey ribbon on Account form in IE "SCRIPT5: Access is denied." in PageLoader.js

MS CRM 2011 on premise.
No problems if accessed via internal address: crm:5555
Go to crm.ourcompany.co.uk:5555 in IE and load account page and the ribbon is totally grey. (Not disabled - every pixel is the colour grey.)
In Chrome and Firefox the ribbon is loaded fine.
Browser console in IE, Chrome and FF all say access errors.
I can see they are trying to access crm:5555.
IE says:
SCRIPT5: Access is denied.
PageLoader.js, line 1 character 1226
The second line above is presented as a link. Clicking it shows me this: http://pastebin.com/bBadk9HS
The full path is http://crm.ourcompany.co.uk:5555/_static/_common/scripts/PageLoader.js?ver=-1056260279
P.S. IE is "Browser Mode: IE10 Document Mode: IE9 standards".

After Long investigation I have found out the reason for same issue like this.
We had previous rollup activity feed solution.
After importing the new version of Activity feeds this hectic issue was sorted out.
Activity feed new solution is available with rollup up package.it can be found by exacting the rollup package. Previously this was available in Microsoft Dynamic market place.

It turns out that the problem is an address lookup plugin on the Account form.
This is trying to access http://crm:1999, which is a 404, and http://crm:5555, which isn't allowed.
Solutions are to fix the server on http://crm:1999 and set up proper managed internal and external URLs so it'll know whether http://crm:5555 or http://crm.ourcompany.co.uk:5555 or remove the plugin.

Access Denied for localstorage in IE10

Yesterday I installed Windows 8 and am now trying to understand why I am getting an "Access Denied" message when accessing localstorage. The page is being served on the same PC with the browser (http://localhost). My feeling is that one of the security settings in IE 10 is wrong, but I haven't figured out which one.
The line of JavaScript code triggering the error is:
if(window.localStorage.getItem('phone') == null)
The code works fine in the latest version of Chrome.

Our users were having issues with web sites using the LocalStorage feature (including Twitter) on Windows 8 with IE 10. When accessing one of these sites with the F12 Developer Tools open, a SCRIPT5: Access is denied message appeared on the console.
After working with Microsoft support, we identified the cause. It turned out to be a problem with the settings on the C:\Users\username\Appdata\LocalLow folder in their user profile.
Each folder on your computer has an integrity setting. More information about the purpose of this setting is here: http://msdn.microsoft.com/en-us/library/bb625964.aspx
The integrity setting on the AppData\LocalLow folder (and its subfolders) in each user's profile is supposed to be set to "Low" (hence the name). In our case, the integrity level was not set correctly on this folder. To rectify the problem, run the following command in a command prompt window:
icacls %userprofile%\Appdata\LocalLow /t /setintegritylevel (OI)(CI)L
(If there is more than one user account on the computer and the other users are having the same issue, the command needs to be run under each affected user's account.)
As for how this setting got changed in the first place? In our case, it was caused by a problem in the customized Windows 8 image we deployed to our workstations. For others that are having the issue, my research has revealed that the use of a "system cleaner" utility may be to blame.

Doubtless there might be many causes of the same symptoms, but here is what fixed this issue for me.
I had just one of many Windows 7 PCs with IE11 exhibiting the symptom of "Access Denied" on attempting any JavaScript involving window.localStorage from otherwise reputable and well-behaved web sites. Use of Process Explorer revealed that the proximal cause was an ACCESS DENIED when taskhost.exe (acting on behalf of Internet Explorer) tried to open DOMStore\container.dat for Generic Read-Write. In fact, it was worse than that: if I deleted container.dat, the same ACCESS DENIED occurred, even through the file did not exist any more. And, if I deleted the (hidden) DOMStore folder, when taskhost.exe attempted to recreate it, that received ACCESS DENIED as well.
After two days of chasing false leads, the final solution was this:
The registry entry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\LowCache\Extensible Cache\DOMStore\CachePath
(do note the LowCache in that string) was incorrectly set to:
%USERPROFILE%\AppData\Local\Microsoft\Internet Explorer\DOMStore
when it should be:
%USERPROFILE%\AppData\LocalLow\Microsoft\Internet Explorer\DOMStore
with the consequence that low-integrity localStorage requests were being directed to medium-integrity regions of AppData disk storage, thus generating ACCESS DENIED errors, and killing the use of JavaScript window.localStorage.
This registry entry must have been wrong for many years: perhaps a side-effect of enthusiastic take-up of buggy platform previews and so on. This error survived a total removal and re-installation of IE11.
There is a similar-looking registry entry for the medium-integrity cache:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\Cache\Extensible Cache\DOMStore\CachePath
and that is correctly left as:
%USERPROFILE%\AppData\Local\Microsoft\Internet Explorer\DOMStore
and should not be changed.

Try enabling the Enhanced Protected Mode in the IE settings, under the Advanced tab, in the Security sub-list. This enables the Microsoft XSS filter. I had similar issues when logging into SE, and fetching google+ notifications, and my first workaround was starting IE with admin privileges. But I think the EP mode will do the trick in your case too.
Related links: Understanding Enhanced Protected Mode

Mark Russinovich always says: "when in doubt, use Process Monitor":
localStorage data gets stored in XML files in the following folder:
C:\Users\[USERNAME]\AppData\Local\Microsoft\Internet Explorer\DOMStore
A profile of the file activity while reproducing the issue can tell you if the problem is caused by missing file access permissions or maybe even an anti-virus program.
I can reproduce the error by adding the read-only attribute to "DOMStore\container.dat". You should check if all file/folder permissions and attributes are set correctly. On my machine, admins and my own account have full permission for the mentioned folder.

Go to Tools/Internet Options/Advanced and under 'Security' select 'Enable DOM Storage' checkbox. This should fix the problem

I added the websites involved to the Trusted Sites section of IE and have not received the error again.

In addition to the already excellent answers here, I'd like to add another observation. In my case, the NTFS permissions on the Windows %LOCALAPPDATA% directory structure were somehow broken.
To diagnose this issue. I created a new Windows account (profile), which worked fine with the localStorage,so then I painstakingly traversed the respective %LOCALAPPDATA%\Microsoft\Internet Explorer trees looking for discrepancies.
I found this gem:
C:\Users\User\AppData\Local\Microsoft>icacls "Internet Explorer"
Internet Explorer Everyone:(F)
I have NO idea how the permissions were set wide open!
Worse, all of the subdirectories has all permissions off. No wonder the DOMStore was inaccessible!
The working permissions from the other account were:
NT AUTHORITY\SYSTEM:(OI)(CI)(F)
BUILTIN\Administrators:(OI)(CI)(F)
my-pc\test:(OI)(CI)(F)
Which matched the permissions of the parent directory.
So, in a fit of laziness, I fixed the problem by having all directories "Internet Explorer" and under inherit the permissions. The RIGHT thing to do would be to manually apply each permission and not rely on the inherit function. But one thing to check is the NTFS permissions of %LOCALAPPDATA%\Microsoft\Internet Explorer if you experience this issue. If DOMStore has broken permissions, all attempts to access localStorage will be met with Access Denied.

This issue may also be caused by having missing or corrupted registry entries. If a reset does not resolve the issue, the LocalLow folder has the correct integrity level, and the DOMStore registry value is correct, run the below commands to re-register IE in the profile:
32 Bit OS:
C:\WINDOWS\system32\ie4uinit.exe -BaseSettings
64 Bit OS:
C:\WINDOWS\system32\ie4uinit.exe -BaseSettings
C:\Windows\SysWOW64\ie4uinit.exe -BaseSettings
See the IE MSDN blog for more details.

PDF files do not open in Internet Explorer with Adobe Reader 10.0 - users get an empty gray screen. How can I fix this for my users?

There is a known issue with opening a PDF in Internet Explorer (v 6, 7, 8, 9) with Adobe Reader X (version 10.0.*). The browser window loads with an empty gray screen (and doesn't even have a Reader toolbar). It works perfectly fine with Firefox, Chrome, or with Adobe Reader 10.1.*.
I have discovered several workarounds. For example, hitting "Refresh" will load the document properly. Upgrading to Adobe Reader 10.1.*, or downgrading to 9.*, fixes the issue too.
However, all of these solutions require the user to figure it out. Most of my users get very confused at seeing this gray screen, and end up blaming the PDF file and blaming the website for being broken. Honestly, until I researched the issue, I blamed the PDF too!
So, I am trying to figure out a way to fix this issue for my users.
I've considered providing a "Download PDF" link (that sets the Content-Disposition header to attachment instead of inline), but my company does not like that solution at all, because we really want these PDF files to display in the browser.
Has anyone else experienced this issue?
What are some possible solutions or workarounds?
I'm really hoping for a solution that is seamless to the end-user, because I can't rely on them to know how to change their Adobe Reader settings, or to automatically install updates.
Here's the dreaded Gray Screen:
Edit: screenshot was deleted from file server! Sorry!
The image was a browser window, with the regular toolbar, but a solid gray background, no UI whatsoever.
Background info:
Although I don't think the following information is related to my issue, I'll include it for reference:
This is an ASP.NET MVC application, and has jQuery available.
The link to the PDF file has target=_blank so that it opens in a new window.
The PDF file is being generated on-the-fly, and all the content headers are being set appropriately.
The URL does NOT include the .pdf extension, but we do set the content-disposition header with a valid .pdf filename and the inline setting.
Edit: Here is the source code that I'm using to serve up the PDF files.
First, the Controller Action:
public ActionResult ComplianceCertificate(int id){
byte[] pdfBytes = ComplianceBusiness.GetCertificate(id);
return new PdfResult(pdfBytes, false, "Compliance Certificate {0}.pdf", id);
}
And here is the ActionResult (PdfResult, inherits System.Web.Mvc.FileContentResult):
using System.Net.Mime;
using System.Web.Mvc;
/// <summary>
/// Returns the proper Response Headers and "Content-Disposition" for a PDF file,
/// and allows you to specify the filename and whether it will be downloaded by the browser.
/// </summary>
public class PdfResult : FileContentResult
{
public ContentDisposition ContentDisposition { get; private set; }
/// <summary>
/// Returns a PDF FileResult.
/// </summary>
/// <param name="pdfFileContents">The data for the PDF file</param>
/// <param name="download">Determines if the file should be shown in the browser or downloaded as a file</param>
/// <param name="filename">The filename that will be shown if the file is downloaded or saved.</param>
/// <param name="filenameArgs">A list of arguments to be formatted into the filename.</param>
/// <returns></returns>
[JetBrains.Annotations.StringFormatMethod("filename")]
public PdfResult(byte[] pdfFileContents, bool download, string filename, params object[] filenameArgs)
: base(pdfFileContents, "application/pdf")
{
// Format the filename:
if (filenameArgs != null && filenameArgs.Length > 0)
{
filename = string.Format(filename, filenameArgs);
}
// Add the filename to the Content-Disposition
ContentDisposition = new ContentDisposition
{
Inline = !download,
FileName = filename,
Size = pdfFileContents.Length,
};
}
protected override void WriteFile(System.Web.HttpResponseBase response)
{
// Add the filename to the Content-Disposition
response.AddHeader("Content-Disposition", ContentDisposition.ToString());
base.WriteFile(response);
}
}

It's been 4 months since asking this question, and I still haven't found a good solution.
However, I did find a decent workaround, which I will share in case others have the same issue.
I will try to update this answer, too, if I make further progress.
First of all, my research has shown that there are several possible combinations of user-settings and site settings that cause a variety of PDF display issues. These include:
Broken version of Adobe Reader (10.0.*)
HTTPS site with Internet Explorer and the default setting "Don't save encrypted files to disk"
Adobe Reader setting - disable "Display PDF files in my browser"
Slow hardware (thanks #ahochhaus)
I spent some time researching PDF display options at pdfobject.com, which is an EXCELLENT resource and I learned a lot.
The workaround I came up with is to embed the PDF file inside an empty HTML page. It is very simple: See some similar examples at pdfobject.com.
<html>
<head>...</head>
<body>
<object data="/pdf/sample.pdf" type="application/pdf" height="100%" width="100%"></object>
</body>
</html>
However, here's a list of caveats:
This ignores all user-preferences for PDFs - for example, I personally like PDFs to open in a stand-alone Adobe Reader, but that is ignored
This doesn't work if you don't have the Adobe Reader plugin installed/enabled, so I added a "Get Adobe Reader" section to the html, and a link to download the file, which usually gets completely hidden by the <object /> tag, ... but ...
In Internet Explorer, if the plugin fails to load, the empty object will still hide the "Get Adobe Reader" section, so I had to set the z-index to show it ... but ...
Google Chrome's built-in PDF viewer also displays the "Get Adobe Reader" section on top of the PDF, so I had to do browser detection to determine whether to show the "Get Reader".
This is a huge list of caveats. I believe it covers all the bases, but I am definitely not comfortable applying this to EVERY user (most of whom do not have an issue).
Therefore, we decided to ONLY do this embedded option if the user opts-in for it. On our PDF page, we have a section that says "Having trouble viewing PDFs?", which lets you change your setting to "embedded", and we store that setting in a cookie.
In our GetPDF Action, we look for the embed=true cookie. This determines whether we return the PDF file, or if we return a View of HTML with the embedded PDF.
Ugh. This was even less fun than writing IE6-compatible JavaScript.
I hope that others with the same problem can find comfort knowing that they're not alone!

I don't have an exact solution, but I'll post my experiences with this in case they help anyone else.
From my testing, the gray screen is only triggered on slower machines [1]. To date, I have not been able to recreate it on newer hardware [2]. All of my tests have been in IE8 with Adobe Reader 10.1.2. For my tests I turned off SSL and removed all headers that could have disabled caching.
To recreate the gray screen, I followed the following steps:
1) Navigate to a page that links to a PDF
2) Open the PDF in a new window or tab (either via the context menu or target="_blank")
3) In my tests, this PDF will open without error (however I have received user reports indicating failure on the first PDF load)
4) Close the newly opened window or tab
5) Open the PDF (again) in a new window or tab
6) This PDF will not open, but instead only show the "gray screen" mentioned by the first user (all subsequent PDFs that are loaded will also not display -- until all browser windows are closed)
I performed the above test with several different PDF files (both static and dynamic) generated from different sources and the gray screen issue always occurs when following the above steps (on the "slow" computer).
To mitigate the problem in my application, I "tore down" the page that links to the PDF (removed parts piece by piece until the gray screen no longer occurred). In my particular application (built on closure-library) removing all references to goog.userAgent.adobeReader [3] appears to have fixed the issue. This exact solution won't work with jquery or .net MVC but maybe the process can help you isolate the source of the issue. I have not yet taken the time to isolate which particular portion of goog.userAgent.adobeReader triggers the bug in Adobe Reader, but it is likely that jquery might have similar plugin detection code to that used in closure-library.

I ran into this issue around the time MVC1 was first released. See Generating PDF, error with IE and HTTPS regarding the Cache-Control header.

For Win7 Acrobat Pro X
Since I did all these without rechecking to see if the problem still existed afterwards, I am not sure which on of these actually fixed the problem, but one of them did. In fact, after doing the #3 and rebooting, it worked perfectly.
FYI: Below is the order in which I stepped through the repair.
Go to Control Panel > folders options under each of the General, View and Search Tabs
click the Restore Defaults button and the Reset Folders button
Go to Internet Explorer, Tools > Options > Advanced > Reset ( I did not need to delete personal settings)
Open Acrobat Pro X, under Edit > Preferences > General.
At the bottom of page select Default PDF Handler. I chose Adobe Pro X, and click Apply.
You may be asked to reboot (I did).
Best Wishes

In my case the solution was quite simple.
I added this header and the browsers opened the file in every test.
header('Content-Disposition: attachment; filename="filename.pdf"');

I had this problem. Reinstalling the latest version of Adobe Reader did nothing. Adobe Reader worked in Chrome but not in IE. This worked for me ...
1) Go to IE's Tools-->Compatibility View menu.
2) Enter a website that has the PDF you wish to see. Click OK.
3) Restart IE
4) Go to the website you entered and select the PDF. It should come up.
5) Go back to Compatibility View and delete the entry you made.
6) Adobe Reader works OK now in IE on all websites.
It's a strange fix, but it worked for me. I needed to go through an Adobe acceptance screen after reinstall that only appeared after I did the Compatibility View trick. Once accepted, it seemed to work everywhere. Pretty flaky stuff. Hope this helps someone.

Hm, would it be possible to simply do this:
The first time your user opens a pdf, using Javascript you make a popout that basically says "If you cannot see your document, please click HERE". Make "HERE" a big button where it will explain to your user what's the problem. Also make another button "everything's fine". If the user clicks on this one, you remember it, so it isn't displayed in the future.
I'm trying to be practical. Going to great lengths trying to solve this kind of problem "properly" for a small subset of Adobe Reader versions doesn't sound very productive to me.

Experimenting more, the underlying cause in my app (calling goog.userAgent.adobeReader) was accessing Adobe Reader via an ActiveXObject on the page with the link to the PDF. This minimal test case causes the gray screen for me (however removing the ActiveXObject causes no gray screen).
<!DOCTYPE html>

I'm very interested if others are able to reproduce the problem with this test case and following the steps from my other post ("I don't have an exact solution...") on a "slow" computer.
Sorry for posting a new answer, but I couldn't figure out how to add a code block in a comment on my previous post.
For a video example of this minimal test case, see: http://youtu.be/IgEcxzM6Kck

I realize this is a rather late post but still a possible solution for the OP. I use IE9 on Win 7 and have been having Adobe Reader's grey screen issues for several months when trying to open pdf bank and credit card statements online. I could open everything in Firefox or Opera but not IE. I finally tried PDF-Viewer, set it as the default pdf viewer in its preferences and no more problems. I'm sure there are other free viewers out there, like Foxit, PDF-Xchange, etc., that will give better results than Reader with less headaches. Adobe is like some of the other big companies that develop software on a take it or leave it basis ... so I left it.

We were getting this issue even after updating to the latest Adobe Reader version.
Two different methods solved this issue for us:
Using the free version of Foxit Reader application in place of Adobe Reader
But, since most of our clients use Adobe Reader, so instead of requiring users to use Foxit Reader, we started using window.open(url) to open the pdf instead of window.location.href = url. Adobe was losing the file handle on for some reason in different iframes when the pdf was opened using the window.location.href method.
