Programmatically restart application when it crashes

Question

I have a Windows application written in C++ that sometimes crashes. Is there a way to programmatically ignore the modal dialog box and automatically relaunch the application?

Answer 1

Something i've learned from viruses: use a service to check that your application is running. If the service detects that the application is not running, start the application. Implement the service however you like.

Answer 2

您可以看看RegisterApplicationRestart函数（最低Windows Vista / 2008）

Answer 3

in vc++:

//-- a Top-level Exception Handler in process level 
LONG WINAPI TopLevelExceptionHandler(PEXCEPTION_POINTERS pExceptionInfo)
{

// find app name to re execute it.
TCHAR szPath[_MAX_PATH];
VERIFY(::GetModuleFileName(AfxGetApp()->m_hInstance, szPath, _MAX_PATH));
CString csPath(szPath);

// re execute.
ShellExecute( NULL, "open",csPath , NULL, NULL, 1 );

//
exit(-1);
return EXCEPTION_CONTINUE_SEARCH;
}


main()
{
   //set a Top-level Exception Handler in process level to re execute app. 
   SetUnhandledExceptionFilter(TopLevelExceptionHandler);
   .
   .
   .
}

Answer 4

Write an unhandled exception handler that relaunches. If you need to be sure you have the memory to do so, preallocate.

If you make recovering from faults too much a guaranteed thing, you risk never fixing the faults.

Plus, it's better to notify someone that it faulted and shutdown. What if you faulted on a problem that will reoccur every time the program starts. Then it looks like your program is always running, but it isn't doing anything.
