#include , test,

CodePudding user response:

#include , test the secret

CodePudding user response:

Everyone, no matter use, after a sticker or a bunch of mistakes...

CodePudding user response:

Is HWND instead of HWMD

HINSTANCE, hPrevInstance here more than a comma in the middle

CodePudding user response:

Is a wndclass. HbrBackground rather than a wndclass. HbrBackgrond

Is the GetStockObject rather than GetStockObject

Is the TEXT rather than TEXT

Small problems too much, only to find it

CodePudding user response:

For problem statement added start a new line/* */comment and then wrote the revised statement
