OK, i get an error that forces my program to close. It only brings it up on a WinME machine and give this message TESTBED has caused an error in USER.EXE./ TESTBED will now close./If you continue to experience problems, try restarting your computer./ It does this after sending an OK which reads a combo box. Anyone have any ideas?

Come on people, someone has to have an idea of whats going on here.

Crashes on IDOK from a dialog

Can you post the function your program crashes in, or at least the specific line in that function that crashes your program crashes on? Without seeing some code it''s tough to guess at what your problem is.

Sure thing:

Ok when the code recieves the IDM_FILE_CONNECT message in WinProc it jumps to this block under WM_COMMAND

case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDM_FILE_CONNECT:
DialogBox(hinstance, MAKEINTRESOURCE(IDD_CONNECT), hwnd, (DLGPROC)ConnectProc);
//MessageBox(NULL,host, "IDM_FILE_CONNECT", MB_OK);
//Error();
break;

.... more ifs and end switch

Then this is the Proc for the Dialog:


///////////////////////////////////////////////////////////
// Dialog Procedure For The CONNECT //
///////////////////////////////////////////////////////////
BOOL ConnectProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
switch(Message)
{
break;
case WM_INITDIALOG:
//MessageBox(NULL,"ConnectProc", "Connect Box", MB_OK);
return TRUE;
case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDOK:


GetDlgItemText(hwnd,IDC_HOST,host,sizeof(host) );
GetDlgItemText(hwnd,IDC_PORT,(char *)port,sizeof(port) );
GetDlgItemText(hwnd,IDC_CHECK_SELFSERVE,(char *)selfserve,sizeof(selfserve) );
WinSockBegin();
//MessageBox(NULL, host, "Connect Box", MB_OK);
EndDialog(hwnd, IDOK);
return TRUE;
}
break;
}
return FALSE;
}



The Program crashes when you click ok. So it must be there at that IDOK message.


I have a few extra messagebox commands commented out that I was using for coding throught this. Error() basically is just a messagebox that displays the error message (if any) that WSAGetLastError() returns.

Pre-thanks to anyone that tries to help!

If the program crashes when compiled in debug mode, try looking at where it actually crashes...if the function it crashes in is part of windows (eg user.exe) then trace through the call stack, to the last called function of your program then try checking the values of the parameters to ensure they make sense...if you can find where it crashes & are still unsure what to do, post the results of this research at least

WOOT!
Figured it out, it was all because of using GetDlgItemText instead of GetDlgItemInt. Guess no one else realized that a port is supposed to be an int hehe oh well.

*complains about the bitmaps not showing up in the dialogs on win2k...*
