Re: Need Help Debugging DoModal Returning -1 In DLL
I didn't know No Fail Create existed! Unfortunately it didn't fix the issue,
and GetLastError returns 0. The function in my DLL looks like such:
unsigned long __cdecl LauncherUIEntry(HINSTANCE hDll)
{
HINSTANCE hOldResource = AfxGetResourceHandle();
AfxSetResourceHandle(hDll);
// Load COM
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);
// Bring up the login GUI
LoginDlg* pLoginDlg = new LoginDlg();
INT_PTR nResponse = pLoginDlg->DoModal(); // nResponse is -1
if (IDOK == nResponse)
{
// Successfully logged in, bring up main window
LauncherMainDlg mainDlg;
mainDlg.DoModal();
}
delete pLoginDlg;
// Unload COM
CoUninitialize();
AfxSetResourceHandle(hOldResource);
return 0;
}
Anything glaringly offensive?

Show some of the code.
Also, mark your dialog with the "No Fail Create" attribute TRUE. If it
comes up and a
control is missing, that explains the problem. Also, did you check the
GetLastError
value?

I am not very MFC englightened so please bear with me on this. I am
creating a MFC application that has some dialogs, then it will dynamically
load a DLL and call an exported function on it that itself displays some
dialogs. Everything works as desired until the DLL tries to DoModal() on
one of its dialogs. The call returns right away with a -1, and I cannot
seem to be able to step into the function, so I don't know what is going
on.
The exported DLL function does start with
AFX_MANAGE_STATE(AfxGetStaticModuleState()); which is what I found while
searching for solutions on the net. If you can give me any pointers or
things I could be missing, I would appreciate it. If you need more info
please let me know what kind would be useful.
