Ok so now I have a start. I created a radio button (even though i want a push button), but I can't figure out how to make it open a MessageBox when clicked.
Code:
CreateWindowEx(NULL, "BUTTON", "", WS_VISIBLE,
150, 150, 50,50,hwnd, (HMENU)IDC_MAIN_EDIT, g_hInst, NULL);
It's not moving the button to where I want, or making it the correct height/width. I also don't know how to link to the MessageBox. Is that first NULL correct? What should be placed there?
That winprog.org site was a lot of help too, thanks.
