win32应用程序框架的两种方式

win32框架最为见的是把主窗口类和初始化窗口以及主窗口回调函数放在同一个文件中，适用于较为小型的软件开发。

先列出最基本的框架，紧接着展示另一种框架，便于比较。个人感觉是从MFC开发中移植过来的，但是程序具有很强的扩展性，适用于二次开发，方便修改。

原框架：

#include <windows.h>LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")//窗口风格优化int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,                    PSTR szCmdLine, int iCmdShow){     static TCHAR szAppName[] = TEXT ("HelloWin") ;     HWND         hwnd ;     MSG          msg ;     WNDCLASS     wndclass ;     wndclass.style         = CS_HREDRAW | CS_VREDRAW ;     wndclass.lpfnWndProc   = WndProc ;     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 = szAppName ;     if (!RegisterClass (&wndclass))     {          MessageBox (NULL, TEXT ("This program requires Windows NT!"),                       szAppName, MB_ICONERROR) ;          return 0 ;     }          hwnd = CreateWindow (szAppName,                  // window class name                          TEXT ("The Hello Program"), // window caption                          WS_OVERLAPPEDWINDOW,        // window style                          CW_USEDEFAULT,              // initial x position                          CW_USEDEFAULT,              // initial y position                          CW_USEDEFAULT,              // initial x size                          CW_USEDEFAULT,              // initial y size                          NULL,                       // parent window handle                          NULL,                       // window menu handle                          hInstance,                  // program instance handle                          NULL) ;                     // creation parameters          ShowWindow (hwnd, iCmdShow) ;     UpdateWindow (hwnd) ;          while (GetMessage (&msg, NULL, 0, 0))     {          TranslateMessage (&msg) ;          DispatchMessage (&msg) ;     }     return msg.wParam ;}LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam){     HDC         hdc ;     PAINTSTRUCT ps ;     RECT        rect ;          switch (message)     {     case WM_CREATE:          return 0 ;               case WM_PAINT:         hdc = BeginPaint (hwnd, &ps) ;                  EndPaint (hwnd, &ps) ;        return 0 ;               case WM_DESTROY:          PostQuitMessage (0) ;          return 0 ;     }     return DefWindowProc (hwnd, message, wParam, lParam) ;}

进行拆分框架：

//initwindow.cpp 用于创建窗口类和实例  
#include "stdafx.h"TCHAR szTitle[]=TEXT("tcpClient");TCHAR szWindowClass[]=TEXT("tcpClient");LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);ATOM MyRegisterClass(PWNDCLASSEX wcex,HINSTANCE hInstance){wcex->cbSize = sizeof(WNDCLASSEX); wcex->style=  CS_HREDRAW | CS_VREDRAW;wcex->lpfnWndProc= (WNDPROC)WndProc;wcex->cbClsExtra= 0;wcex->cbWndExtra= 0;wcex->hInstance= hInstance;wcex->hIcon= 0;wcex->hCursor= LoadCursor(NULL, IDC_ARROW);wcex->hbrBackground=(HBRUSH) GetStockObject (WHITE_BRUSH);wcex->lpszMenuName= 0;wcex->lpszClassName= szWindowClass;wcex->hIconSm= 0;return RegisterClassEx(wcex);}HWND InitInstance(HINSTANCE hInstance, int nCmdShow){HWND hWnd;HINSTANCE hInst;hInst = hInstance; // Store instance handle in our global variablehWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,CW_USEDEFAULT, 0, windowx, windowy, NULL, NULL, hInstance, NULL);if (!hWnd){return hWnd;}ShowWindow(hWnd, nCmdShow);UpdateWindow(hWnd);return hWnd;}
//windowTool.cpp用于创建窗口中各种控件

extern void initTool(HWND hWnd);



#include "stdafx.h"HINSTANCE g_hInstance;int APIENTRY WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR     lpCmdLine,int       nCmdShow){g_hInstance = hInstance;HWND hWnd;MSG msg;WNDCLASSEX WndClass;MyRegisterClass(&WndClass, hInstance);if (!(hWnd = InitInstance(hInstance, nCmdShow))) return FALSE;while (GetMessage(&msg, NULL, 0, 0))     //创建消息循环获取机制{TranslateMessage(&msg);DispatchMessage(&msg);}return msg.wParam;}LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

}
//initwindow.cpp 用于创建窗口类和实例

extern HWND InitInstance(HINSTANCE, int);//对窗口进行初始化并注册热键
extern void initTool(HWND hWnd);

  这样就将最基本的win32进行了拆分，有效的提高了程序的扩展性查找起来也很方便，另外需要自定义资源标识符的时候，建议在resource.h头文件中进行定义，便于统一管理和维护。
