C语言创建语言创建windows窗口实例窗口实例
主要介绍了C语言创建windows窗口实例,本文直接给出实现代码,同时讲解了编码的步骤,需要的朋友可以参考下
耐得住寂寞，禁得起诱惑，这就是程序人生
步骤：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：完整代码：
复制代码 代码如下:
#include <windows.h>
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;
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,
