Application UI Hangs with some unknonw reason.

I have a multi threading application which for no known reason gets hanged after working for few hours. The application makes use of locks only as for synchronization and they are very few in numbers (19-20) in location as well. I wrapped the code which gives the lock and as soon as the lock is taken by any thread I put that thread in on list with the lock information. I also makes it status as acquired. When I release the lock I make the status as release. When a lock is requested it is in waiting state. Now if thread deadlock is there this list can never be empty as at least one lock must be in acquired status and other locks would be in waiting status.

The application UI hangs only in production environment and works fine with local setup. When I get the logs of the above list, the list of thread with locks is always empty when the UI is hanged. I feel that since the list is empty there shall be no deadlock being lock list as empty but I do not know any other reason a UI could be hanged for indefinite period without a thread deadlock.


Can someone please suggest what else could be wrong in the system so as UI is getting hanged. I seriously feel if there is any thread deadlock then it must have appeared in the log which I have already tested by creating some deadlocks on sample code. Whenever there is a deadlock in sample code the threads appear in the list and log which I create but in my application even when the UI is hanged nothing is printed in the log and locks list is empty as well.


Please help and suggest some other pointers which could be the cause of UI hang

Hello All,

I got a problem after installing VS2010, i have already reinstalled VS2010 but the problem persist and now it occurs on VS2008 too.

In my application (WPF and .NET 3.5 SP1) when i open one of the application screens. The application hangs and stopped to work. I discovered that this is because of a GroupBox that have in text Header a Fontsize=16, if i let the fontsize default the problem dont occurs, i use default font "Segoe UI".

I did some testing and discovered that if I simply create a new application in WPF and .NET 3.5 and add a button on the screen and increase the font size of button to size of 14, 16 or 18, when I give F5 the application will hang. In design mode its works, but when i run the application its presents the problem.

The font dont have any problem because i can use it normally on "Notepad" or "Word" and when i create a new application in WPF and .NET 4 its works perfectly, it just give problems in .NET 3.5. Anyway i already reinstalled the Segoe UI font too.

If i change the font to Segoe UI Symbol or any other and change the size to 14, 16, 18 its works normally, just with the default font Segoe UI and font size 14, 16 or 18 it dosnt work.

What could I do to solve this problem???

Hi All,


We have had coded UI test running stable for past few months, recently we change our application source code from 3.5 to 4.0 framework.


Now we are getting coded UI test throwing the following exception whenever it tries to click any links or button

I am trying to use Coded UI test cases for measuring the response time of a desktop applicaton. Currently we are using functions like Stopwatch and WaitForControlReady(). but we are not getting a very accurate response time as compared to manual testing.

Please let me know if there is any other better way of optimizing the code to measure the response time of the UI accurately.


I added a couple more reason codes to the "Active" state, and left "New" as the default.
However, these new codes are not available in a dropdown and the Reason field remains READ ONLY at all times.
Cannot find what is triggering this Read Only state, or how to allow the other values to be selectable.
Would like Reason to be an active and available drop down when there are other options available for that state.

For example, Active "new", can now become Active "In progress".
I would prefer to avoid adding more in between states if possible because of the implications on all the reports....just more reasons.




Any solution/work around for following problem?

I change the state of a bug from Active to Resolved with reason Deferred. After that the state is changed from Resolved to Closed. Then the reason is changed from Deferred to the default reason Fixed.
Would be nice if the reason field would keep the previous value if that is one of the options for the new state transition. If there is a not matching value, then the default reason should be presented.

Would be nice if TFS2010 would support this.

I had a frustrating morning trying to fix this issue . All i was trying to do is to create a new ASP.NET website .

Once when i choose File - > New -> web site, the New Website selection window will open up. I will choose Asp.Net website (to be created under localhost) and hit ok . I will see the Solution explorer displaying App_data and the Default.aspx nodes and that is it. Visual studio will hang right there . I tried restarting IIS, repairing Framework 2.0  etc etc. Nothing worked .

The following steps solved the problem.

1. open your IDE .

2. Click Tools -> Import and Export Settings

3. In the Import and Export Settings Wizard , choose the Reset all Settings option .

4. Hit Next and follow directions from there .

NOTE :  Your IDE may hang due to several reasons and this solution may or may not work depending on the actual reason . For me , this solution worked .

Give it a shot......




Hi all,

i made a simple single form application that consist on webbrowser control, a textbox and a button. if i navigate to particular page which cause webbrowser control to hangs, all application hangs. To test this behavior use this page http://www.maxthon.com/test/freeze_by_dom.htm and then click "Freeze!" button.

Is there a way to prevent this? How can i limit the hang to webbrowser and not to affect the application (i want the application to be responding in any case)? I need a solution or even a logical concept to proceed.

Please help me!!



I have created a application whihc has following structure.

Application(lets say X) source code written using VS 2005 IDE in C#,there are dll's imported into it which are having functions to invoke another application(lets say Y).This imported dll's are created using VS 2008 IDE in C++.

  My C# application X works fine it imports dll & calls functions written within it.

 When a call to start aplication Y made from imported dll application starts fine but original app. X goes in hang state.

Event viewer has following info. 

Source : Application Hang

Type: Error

Category: (101)

Event ID : 1002

Hanging application X.exe, version, hang module hungapp, version, hang address 0x00000000.

Please let me know cause & solution for this issue.


I have two problems of using LoadPicture function. The first one is when load a corrupted picture, VB6 can return invalid picture run-time error under IDE. However if the code compiled to an exe file, it with hangs my application when loading a corrupted picture.

The second one is it will casue access violation at memory reading

The following is the code:

Private Sub Command1_Click()
On Error GoTo trap:
    Picture1 = LoadPicture("invalidpic.jpg") 'the corrupted file
Exit Sub
MsgBox Err.Description, vbExclamation, "Error"
End Sub

When executive the compiled .exe file, it can goto to the error handler when command button was clicked first time. When click the button at the second time, it will cause access violation to shutdown the application.

I'm using VB 6 SP6 + Windows Server 2003 (x86) SP2 with 4GB ram (PAE enabled)

I've tested the OleLoadPicture function to load a picture under C++. It give me the same result. I found that the error is cause by the OleLoadPicture function. It seems that this function cause memory corruption or infinely looping when reading the corruption images.

This is a know issue in Windows 98, 2000 and XP. Does anybody know how to fix this under Windows Server 2003?



      How can i handle when an application is hanging. (ie) I need to close the application programatically when the application is hanging in some ubnormal situation.







Met a issue about application hang on vista:

As we used auto test tools to perform some software testing works, and after several days' running, some clients may hang,

then vista will popup a dialog to indicates that message, and ask if we need force the hang app close. Certainly our auto test tools

closed the application by accident, so we missed the best chance to find the root cause maybe.

My concern is if we can config to turn off the application busy hang dialog even there was hang happen, just let the application hang there like winXP did?





i have a server application and it runs on windows 2008 web server for backup.

server application is created by VC++ 6.0 ( uses _open, _write, open ssl,..) to receive the data and store in storage. 

application was fine when it was running in windows 2003 server. After moving to Windows web 2008 , we are facing unpedictable issues.

ssue 1: File creation on storage is slow after running the server application for some time. ex, when we tried to create a files in storage after running the servers more than 5 mins to create 5 to 10 files. (But this issue is not often, currently we are fixing this issue by restarting the server application)

Issue 2: some time we are not able to close the server application (created using vc++ 6). it takes lot of time to close/terminate the application. we tried via task manager, some time task manager is not closing the server app, and some time it shows the message as "unable to terminate, access denied message". 

Please provide your solutions if you faced this issues in windows 2008 web server for vc++ 6 application.

My System Windows XP > Application Hangs, EVENT ID 1002 after every Six days




An application has more than 64 child processes.

To check if any child process exited,
one of the application thread calls "WaitForMultipleObjects".

Since the limit for number of handles that can be
supplied to "WaitForMultipleObjects" is 64,
a loop that only passes 62 process handles
to "WaitForMultipleObjects" in one iteration
is present. In the next iteration and so on, the
remaining process handles (62 or less at a time)
are passed to "WaitForMultipleObjects".
The timeout passed to "WaitForMultipleObjects"
is 1 second and the bWaitAll is false;

There are other threads in application
that create windows and use "GetMessage",
The calls to "MsgWaitForMultipleObjects" is with timeout.

All the threads in the application are hung as shown in the below
stack trace:

From the MSDN manual page of "WaitForMultipleObjects":

DWORD WINAPI WaitForMultipleObjects(

  __in  const HANDLE *lpHandles,
  __in  BOOL bWaitAll,
  __in  DWORD dwMilliseconds


"Use caution when calling the wait functions and code that directly or
indirectly creates windows. If a thread creates any windows, it must
process messages. Message broadcasts are sent to all windows in the
system. A thread that uses a wait function with no time-out interval
may cause the system to become deadlocked. Two examples of code that
indirectly creates windows are DDE and the CoInitialize function.
Therefore, if you have a thread that creates windows, use
MsgWaitForMultipleObjects or MsgWaitForMultipleObjectsEx, rather than

-> But all the "WaitForMultipleObjects" and the
"MsgWaitForMultipleObjects" calls are being made with timeouts
    and the "bWaitAll" is false.

I am unable to find is hang because of the application threads or the
other unknown threads.

Can there be some suggestions on how to find the cause of all threads
being hung and
what has initiated the hang ?

I have created the process dump from windbg. Using this, can we derive
some more information about
hung reason ?

I have a winforms applications that sends data from the COM port using XModem protocol. I am sending data from "COM12" and then the machine responds to the data on the same comport. Here is what I am doing

SerialPort port = new SerialPort("COM12");
//other properties are set by default and are what I need

Everytime it reaches port.Read my application freezes. I cannot even move it. I tried putting the port.Read in a try catch block but am not getting any exception, as it does not even reach the catch block. I waited thinking it might time out but is not the case either.

Does any body know why this would be happening and how can I fix it.



I have a strange problem that I'm having real trouble solving. I'm working on a WinForms Application (.NET version 2.0.50727). Everything works fine but from time to time the application hangs on the client machines. The client machines are running on Windows XP Professional SP3. I thought that this must be a concurrency problem but I only use threading at application startup and this isn't when the problem occurs. Strangely the problem normally occurs when the application is idle. I had a timer in the application but I've removed this and the problem still occurs. I really don't understand what's going on. I cache quite a lot of data so I was wondering whether it could be something to do with the Garbage Collector. Also, I'm using Crystal Reports version 11 which strangely launches threads from time to time. Also, we have Symantec AntiVirus running on the machines. Sorry I don't have a stack trace, I only have the Event Viewer message:

module blocked hungapp, version, blocked address 0x00000000.

If anyone has any ideas then let me know. I created a dump file of the application but when I opened it in Visual Studio I couldn't make any sense of it. I don't think the Symbols were properly loaded. Thanks in advance for any help - I'd really appreciate it.

hello guys, all you said was an answer but, now i have new error, it load, then after a second whole application hang....

but when i use this in a function such thing wont happen...

i use the function you recomanded :


 sender, EventArgs e)
   //StartCoroutine(LoadAds()); in unity engine



    //Download Ads cache file

    WebClient webClient = new
    webClient.DownloadFileCompleted += new
    webClient.DownloadProgressChanged += new
), "c:\\list.cch"
 { }


also this one has bug


 sender, EventArgs e)
   //StartCoroutine(LoadAds()); in unity engine

   EventHandler delegateInvoker = new
, EventArgs.Empty);

 Sender, EventArgs e)

    //Download Ads cache file

    WebClient webClient = new
    webClient.DownloadFileCompleted += new
    webClient.DownloadProgressChanged += new
), "c:\\list.cch"
 { }
