{if(!InitWindowsApp(hInstance, nShowCmd)){

}return Run();

Exercise

Change the main window:the background color

the icon

the cursor

the title

the size

Change the message box:the title, sentence, and buttons

Create another message box when …the right button of a mouse is clicked

the enter key is pressed


Hint (1)

bool InitWindowsApp(HINSTANCE instanceHandle, int show){

WNDCLASS wc;

wc.style = CS_HREDRAW | CS_VREDRAW;wc.lpfnWndProc = WndProc;wc.cbClsExtra = 0;wc.cbWndExtra = 0;wc.hInstance = instanceHandle;wc.hIcon = ::LoadIcon(0, IDI_APPLICATION);wc.hCursor = ::LoadCursor(0, IDC_ARROW);wc.hbrBackground = static_cast<HBRUSH>(::GetStockObject(WHITE_BRUSH));wc.lpszMenuName = 0;wc.lpszClassName = "Hello";

if(!::RegisterClass(&wc)) {

::MessageBox(0, "RegisterClass - Failed", 0, 0);return false;

}


Hint (2)

MainWindowHandle = ::CreateWindow("Hello","Hello",WS_OVERLAPPEDWINDOW,CW_USEDEFAULT, CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,0,0, instanceHandle,0);

if(MainWindowHandle == 0){

::MessageBox(0, "CreateWindow - Failed", 0, 0);return false;

}

::ShowWindow(MainWindowHandle, show);::UpdateWindow(MainWindowHandle);

return true;}


Hint (3)LRESULT CALLBACK WndProc(HWND windowHandle,

UINT msg, WPARAM wParam,LPARAM lParam)

{switch( msg ){case WM_LBUTTONDOWN:

::MessageBox(0, "Hello, World", "Hello", MB_OK);return 0;

case WM_KEYDOWN:if( wParam == VK_ESCAPE )

::DestroyWindow(MainWindowHandle);return 0;

case WM_DESTROY: ::PostQuitMessage(0); return 0;

}return ::DefWindowProc(windowHandle, msg, wParam, lParam);

}


Result – Exercise

제출방법2007. 4. 5 수업시간전까지

Exercise에대한프로그램을작성 (예: “학번.cpp”) + 실행결과 (본강의자료 10쪽또는 20쪽과같은출력이미지, 예: “학번.jpg”)

2개파일을압축한 “학번.zip”을웹에 upload 할것
