To get the click event from the button we process the WM_COMMAND message. But before we can check what button generated the message, we should assign a control id when we create the button

.if uMsg == WM_COMMAND
.if wParam == 100 ; is it MAKELONG(BN_CLICKED, 100) ?
szText msg, "Button was clicked"
invoke MessageBox, hWin, ADDR msg, NULL, MB_ICONINFORMATION
.endif
.elseif uMsg == WM_CREATE

...

szText szButtonClass, "Button"
invoke CreateWindowEx, 0, ADDR szButtonClass, ADDR butn1, WS_CHILD OR WS_BORDER OR WS_VISIBLE,
0, 0, 100, 100, hWin, 100, hInstance, NULL

...

I don't know what your function PushButton does but I have a feeling parameter 3 is used to set the control id :D.

Hope it will help you :)

Edit: You can also save the Button HWND and compare it with the lParam of WM_COMMAND. I prefer to use the control ID though.
