Hi all,
Would the CreateDirectory function throw an exception if the directory that it must create already exists? (Stupid question I know ....  )
Many Thanx

what does the msdn say about it ?
|
|

toxcct, I have read what MS has posted on MSDN. And the only relevent information I could find was that the return value would be ERROR_ALREADY_EXISTS, but that doesn't answer my question, or does it?

yes it does... returning a value means that it knows that case, and don't throw an exception.
moreover, know that the Win32 API is written in C, not C++, so exceptions are unknown in C.

Thank you toxcct, and thats why you are a MVP and I'm not ...

SEH in not a feature of standard C but that can be used in C on Microsoft systems and the OS does throw SEH exceptions at times (not in this case however).

No, It will return 0.
And GetLastError returns ERROR_ALREADY_EXISTS.
i.e.
BOOL bCreated = CreateDirectory(..);
if (bCreated ==FALSE )
{
if (GetLastError() == ERROR_ALREADY_EXISTS)
{
}
}

Disabling a radio button (or any window, for that matter) can be done by calling the object's EnableWindow() method with the parameter FALSE.

CWnd::EnableWindow(FALSE);

I've used this class in the past for just such a requirement. It's easy to use.
