If you're trying to get a device context or something like that, if there's a problem with the value, then I'd be concerned. Quite frankly, as long as the function doesn't indicate an error, I don't worry about what the actual value is.

>>If you call GetLastError after you get a valid instance hand it may very well retrurn 127. However, it only needs to be called when GetClassLong returns 0. In that case, calling GetLastError will return the reason GetClassLong didn't return a valid instance handle.

Tony,

Sorry, forgot to give the source for the error codes. I get them from the ERRORS.H include file that's on the MSDN CD set. I don't know of another source, maybe someone else does.
