Question

I’m trying to get my CDialog based application to close. I call CWnd::OnClose() and then the debugger goes into windows system files. In the debugger output window I get these looping lines indefinitely.

The thread ‘Win32 Thread’ (0x1040) has exited with code 0 (0x0).
The thread ‘Win32 Thread’ (0x2fa4) has exited with code 0 (0x0).
The thread ‘Win32 Thread’ (0x1ca0) has exited with code 0 (0x0).
‘LifescanDatabaseApplication.exe’: Unloaded ‘C:\Windows\SysWOW64\davclnt.dll’
‘LifescanDatabaseApplication.exe’: Unloaded ‘C:\Windows\SysWOW64\davhlpr.dll’
‘LifescanDatabaseApplication.exe’: Loaded ‘C:\Windows\SysWOW64\davclnt.dll’, Cannot find or open the PDB file
‘LifescanDatabaseApplication.exe’: Loaded ‘C:\Windows\SysWOW64\davhlpr.dll’, Cannot find or open the PDB file

Any ideas what I’ve broken or how I should track it down?
Thanks,

Edit
The function OnClose() for the dialog is shown here;

void CApplicationDlg::OnClose()
{
    UpdateData(TRUE);
    if(AfxMessageBox(_T("Are you sure you want to close? If so, no more updates will be issued"),MB_YESNO)==IDYES)
    {
    Logger * instance = Logger::Instance();
    if(instance!=nullptr)
    {
      instance->writeToLogFile("Application shutdown.");
    }
        CWnd::OnClose();
    }
}

I’ve traced this through with a debugger through the Cwnd::OnClose() command. Problem is, the code isn’t getting back to the part that calls the dialog box to run EndDialog. I think I’ve altered something elsewhere in the dialog box code that is stopping this working.

Edit 2:
Replacing CWnd::OnClose() with this->EndDialog(0) appears to fix the problem, but this is worrying.

Answer 1

The acutal problem was some confusion in the id’s on the buttons which meant that a handler was being called that caused a method to run that took a very long time to complete.

Fixed that and everything worked. Thanks for your help though
