windows程序设计之简单界面入门

突然自己想完整地写一款mm，除了网络通信、文件操作之类的功能类代码外，还要搞一个界面的东西。想了想，为了快速看到成果就学学界面编程吧，也方便看别人的带界面的代码。于是乎，决定windows编程先从界面开始写。

新建一个空的win32工程，只有以下代码：

#include "stdafx.h"
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR     lpCmdLine,
int       nCmdShow)
{
// TODO: Place code here.

return 0;
}

然后贴上一个示例代码，几乎是同一的格式，vs自动生成的页差不多这样子。

// WIN32APP.cpp : Defines the entry point for the application.
//

#include "stdafx.h"

LRESULT CALLBACK MainWndProc(HWND,UINT,WPARAM,LPARAM);

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR     lpCmdLine,
int       nCmdShow)
{
// TODO: Place code here.
char szClassName[]="MainWClass";
WNDCLASSEX wndclass;

wndclass.cbSize=sizeof(wndclass);
wndclass.style = CS_HREDRAW|CS_VREDRAW;
wndclass.lpfnWndProc = MainWndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
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 = szClassName;
wndclass.hIconSm = NULL;

RegisterClassEx(&wndclass);

HWND hwnd = CreateWindowEx(
0,
szClassName,
"My first Window!",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL);

if(hwnd == NULL)
{
MessageBox(NULL,"create windows error !","error",MB_OK);
return -1;
}

ShowWindow(hwnd,nCmdShow);
UpdateWindow(hwnd);

MSG msg;
while (GetMessage(&msg, NULL, 0, 0))
{

TranslateMessage(&msg);
DispatchMessage(&msg);

}

return (int) msg.wParam;
}

LRESULT CALLBACK MainWndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
char szText[]="most simple window";
switch(message)
{
case WM_PAINT:
{
HDC hdc;
PAINTSTRUCT ps;
hdc = BeginPaint(hwnd,&ps);
TextOut(hdc,10,10,szText,strlen(szText));
EndPaint(hwnd,&ps);
return 0;
}
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd,message,wParam,lParam);
}

这里记录一下如何添加图标资源和菜单：











其实很简单，代码也很容易懂，菜鸟只是记录一下。

再添加一个图标玩玩





继续前进！哈哈！
