You don't understand how Task Manager does an "End Process", do you??

When you "End Process" something in Task Manager, it first tries to shutdown the process gracefully by sending a WM_CLOSE message to the app's main window. If the app doesn't respond to it, Task Manager will call TerminateProcess on the targeted process which will immediately halt all threads in the process, wait for any pending I/O operations to complete and then free up the memory that the process occupies.

When I say halt the process/threads, I mean your process stops executing immediately. Your code never gets notified of anything and never gets a chance to respond to ANYTHING. It just ceases to exist. That's why your code never gets executed.

Yes. You have two applications, that should act like a single. It's called a dirty hack.

There are enough known alternatives to the hack; instead of closing CALC when you exit, have CALC check whether you are still alive (poll using a backgroundthread) and exit if you ain't. Create a watchdog (a third app) that checks whether both are alive. Create a SERVER and send a heartbeat. Create a remote thread in CALC.exe and hide your check there.

In your case the watchdog is easiest; I'm betting a banana that your CALC is a native app and that you don't have the code.

How to debug Visual Studio Crashing

Hello,

This is now starting to get out of hand. Every time I have to build my project Visual Studio 10 crashes on me without telling me why. I have tried starting Visual Studio with writing a log file in the command prompt. And starting Visual Studio in SafeMode in the command prompt.

The log file does not show that anything went wrong and Safemode didn't help because I got the same results: crash.

My suspicion is that one of my many references (dlls) might be corrupt or faulty. Should I remove them all and load them back in?

Can anyone offer some suggestions or links on how to debug why Visual Studio crashes during a build? Any help would be greatly appreciated.

That sounds like a tough one. Because you say, "crashes during a build" I'm assuming that you can open VS and your solution without problem. When you start the build, the problem occurs. If that's correct, I'd try watching very carefully the output window to get clues about how far the build progresses before the crash. You've probably already done that, leading to your suspicion that a dll might be the problem.

Another thing I would try is this. Delete all output files produced by a build. (Does Build / Clean still work?) Close VS and make sure everything was cleaned, or perform the task manually. Next I'd delete the .suo file. This is a hidden file in the same directory as your .sln file.

If that doesn't help, I'd hope for more suggestions from other people here. Smile | :)

Good luck!

I have tried deleting some of the files, but I have not tried the .suo file. Also, I am going to retry clean and a project clean. Not sure if there is difference between the two, but at this point I will try anything to get this working.

Thanks for the feedback!

Did you check your event log?

I have not looked into the event log, but only used the Visual Studio logging method. As I mentioned before the VS log got me no where. I will try the event log this time and hope it proves more informative. Thanks for the advice.

You could try a re-install of VS, which may resolve it. I don't know of any published methods of debugging, but if you report the problem to Microsoft they may have some suggestions.

One of these days I'm going to think of a really clever signature.

Thanks for the feedback. This thought has indeed entered my mind. I may do this if nothing else works.

I know Microsoft get a bad press sometimes, but I had a Visual Studio problem a couple of years ago and found the response from them to be very good.

I will sure will try that. This may be a silly question, but can you link me to where I can inform MS of my frustration? Not sure if I should post it at their forums or is there a separate place that handles these type of issues?

i am developing application in vb.net and my application is working fine. i want to add some code to application that should get executed only when it is starting for the first time.

if anyone has done already, please let me know.
Any help is greatly appreciated.

Thanks

Use a Mutex[^] to check if instances of your app are already running. If not, you can execute your code.

Richard MacCutchan20-Aug-12 21:13

20-Aug-12 21:13

It depends what you mean by first time. If you mean first time among a number of concurrent executions, then use a mutex as suggested by Shameel. If you mean first time among consecutive executions or first time ever, then you probably need to add a flag to your app.config or to the registry.

One of these days I'm going to think of a really clever signature.

..to setup the environment for your app? How about using an installer?
