如何用C語言寫出windows視窗程式？下面內容由小編為大家介紹C語言建立windows視窗例項，供大家參考!
步驟：
1.在WinMain中定義各種變數
2.註冊視窗類RegisterClass
3.建立視窗CreateWindow
4.顯示視窗和更新視窗
複製程式碼 程式碼如下:
ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;
5.訊息迴圈
複製程式碼 程式碼如下:
while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
完整程式碼：
複製程式碼 程式碼如下:
#include
LRESULT CALLBACK MyProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd )
{
MSG msg;
HWND hwnd;
static TCHAR szAppName[] = "hl";
WNDCLASS wndclass;
e = CS_HREDRAW | CS_VREDRAW;
sExtra = 0;
dExtra = 0;
WndProc = MyProc;
tance = hInstance;
n = LoadIcon(NULL,IDI_APPLICATION);
sor = LoadCursor(NULL,IDC_ARROW);
ackground= (HBRUSH)GetStockObject(WHITE_BRUSH);
MenuName = NULL;
ClassName= 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 am;
}
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);
}
