You will have to define a new button, at the top, under the existing definition ie
then create a new button in the WM_CREATE case.
Note the IDB_BUT_2 (- the new definition) and the 200 (- height adjustment) in the line above compared to your original button
#define IDB_BUT_2 1002 then create a new button in the WM_CREATE case.
CreateWindow("button", "Press Me!", WS_VISIBLE | WS_CHILD, 20, 200, 120, 30, hWnd, (HMENU) IDB_BUT_2, NULL, NULL);Note the IDB_BUT_2 (- the new definition) and the 200 (- height adjustment) in the line above compared to your original button
//I tryed but I still have one push button
//Please help me

if (wParam==IDB_BUT)The button ID is extracted with
LOWORD(wParam)And PLEASE use code tags, it makes it easier to read your source code.

You can go back edit your posts to add code tags.
