I have already fix this. The function createwindowex returns zero
that means the window failed to create but not to show

Program crashing is different than a run-away program.

Good! Then I can exit my program by intentionally crashing it.

Thank you!


If that is what you call professional programming then yes you can! Actually why use other Win API functions? There is theoretically no need to use IsDebuggerPresent() for example since you can access all memory structures required to duplicate the functionality directly from your ring 3 module. However if MS changes one pointer address it will fail. Also you will need to correct your code when switching from 32 to 64 bit app. That is another reason why using API "sometimes" is actually a benefit and not a drawback Wink

This is a sample code to illustrate how you should call CreateWindowEx() function and not the complete solution. Have you tried compiling provided C code? Probably note since it is incomplete. When porting from one language to another one you need to have complete code or be sure to setup environment proper way. Just my 2 cents...

see thie code on this link below there you read:

<Here is the complete code to create the window. Remember that WindowProc is still just a forward declaration of a function.>

tixvin: The C-code you posted is not complete in any way. I suggest you look at the fasm example for 64-bit window creation. The fasm example works correctly. Don't bother with broken C-code you found somewhere, it is wasting your time.
