What do you mean by there's no CreateWindowA/CreateWindowW in your user32.dll?
I'm pretty sure there is!

This is correct, CreateWindow is a macro in C that puts the value 0 as the dwExStyle parameter and calls CreateWindowEx.

This is also the same with DialogBox which is a macro for DialogBoxParam with a 0 value for dwInitParam.

There is actually quite a lot of this happening in the API. The above two are just the common ones that catch people out most often.

Oh yeah! You reminded well, revolution! It's really a macro.
I remember not using DialogBox() anymore because I wanted to use the actual API instead.
