I am running the following code in CE5.0

dword always comes back with an error code of 6 which is invalid handle. The
Call GetLastError only immediately after you call the function you are
trying to check, and only if that function fails. I don't think
ShowWindow ever fails, so calling GetLastError after calling
ShowWindow will be misleading. I suggest the following modification:
CDialog* tempDlg = new CDialogTestDlg();
if (!tempDlg->Create(IDD_DIALOGTEST_DIALOG))
{
DWORD dword = GetLastError();
return;
}
m_pMainWnd = tempDlg;
tempDlg->ShowWindow(SW_SHOW);
window visually appears to be created successfully 80% of the time. The other
20% of the time we are missing fields on the dialog and the application
crashes. Some of the times we notice the dialog is missing fields, we get an
assert on the windows handle, but most of the time we don't. This code is the
same on pocket pc 2003 and windows moblie 5.0 and we do not get the error
I don't have any explanation for the intermittent part. I also don't
see anything in your code snippet that should behave differently on
Pocket PC 2003 and Windows Mobile 5. However, the code in you snippet
might have problems if your menus are set up correctly. Are you using
proper Pocket PC menus?
code 6 from GetLastError. We have also noticed this happen on the Create call
everywhere else in the application. Any help that can be provided would be
greatly appreciated.
