1. win32 응용 프로그램을 기반으로 두 개의 버튼을 추가합니다. 하나는 일반 BS_PUSHBUTTON 버튼이고 다른 하나는 비트맵 버튼입니다.
2. HWND hButton1 = CreateWindow(_T("버튼"), _T("Btn1"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON, 100, 100, 100, 30, hWnd, (HMENU)btn1, hInst, NULL);
첫 번째 매개변수는 "버튼"이어야 하고, 두 번째 매개변수는 버튼의 이름이고, 세 번째 매개변수 WS_CHILD는 자식 창을 의미하고, WS_VISIBLE은 표시됨을 의미하며, ShowWindow를 사용하여 버튼이 표시되는지 여부를 설정할 수 있습니다. BS_PUSHBUTTON은 데모입니다. 버튼, 다음 몇 개 매개변수는 버튼의 위치입니다...
첫 번째 테스트에서 버튼이 표시되지 않는 것으로 나타났습니다.테스트 시 프로젝트 이름을 "버튼"으로 설정하여 버튼이 표시되지 않도록 하십시오.
