C语言怎样创建windows窗口

耐得住寂寞，禁得起诱惑，这就是程序人生 步骤：

1.在WinMain中定义各种变量 2.注册窗口类RegisterClass 3.创建窗口CreateWindow 4.显示窗口和更新窗口 复制代码 代码如下:

ShowWindow (hwnd, iCmdShow) ; UpdateWindow (hwnd) ; 5.消息循环

复制代码 代码如下:

while (GetMessage (msg, NULL, 0, 0)) {

TranslateMessage (msg) ; DispatchMessage (msg) ; }

完整代码： 复制代码 代码如下: #include LRESULT

CALLBACK

MyProc(HWND

message,WPARAM wParam,LPARAM lParam);

hwnd,UINT

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd ) { MSG msg; HWND hwnd;

static TCHAR szAppName[] = hl; WNDCLASS wndclass;

wndclass.style = CS_HREDRAW | CS_VREDRAW; wndclass.cbClsExtra = 0; wndclass.cbWndExtra = 0; wndclass.lpfnWndProc = MyProc; wndclass.hInstance = hInstance;

wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION); wndclass.hCursor = LoadCursor(NULL,IDC_ARROW); wndclass.hbrBackground=

(HBRUSH)GetStockObject(WHITE_BRUSH); wndclass.lpszMenuName = NULL; wndclass.lpszClassName= szAppName; if(!RegisterClass(wndclass)) {

MessageBox(NULL,TEXT(error),TEXT(title),MB_ICONERROR);

return 0; }

hwnd = CreateWindow(szAppName, TEXT(Hello),

WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL );

ShowWindow(hwnd,nShowCmd); UpdateWindow(hwnd);

while(GetMessage(msg,hwnd,0,0)) {

TranslateMessage(msg); DispatchMessage(msg); }

return msg.wParam;

} LRESULT

CALLBACK

MyProc(HWND

hwnd,UINT

message,WPARAM wParam,LPARAM lParam) {

switch(message) {

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

return DefWindowProc(hwnd,message,wParam,lParam); }
