在Win32控制台程序中添加Windows窗口

控制台程序和窗口程序的区别就在于窗口程序有一个消息循环， 处理窗口事件。本文给出了在控制台程序中使用窗口的代码例子。

对话框例子

 

// Learning.cpp : Defines the entry point for the console application.//#ifndef _MT #define _MT #endif #include "stdafx.h"#include <windows.h>#include "resource.h"#include <process.h>// global flag bool bDone = false; //this function is called by a new thread void InputThreadProc( void *dummy ) { // create the dialog window HWND hWnd = ::CreateDialog(NULL,MAKEINTRESOURCE(IDD_DIALOG1),NULL,NULL); if ( hWnd!=NULL ) { // show dialog ::ShowWindow(hWnd,SW_SHOW); } else { printf("Failed to create dialog/n"); bDone = true; return; } // message loop to process user input MSG msg; while(1) { if ( ::PeekMessage(&msg, hWnd, 0, 0, PM_REMOVE) ) { if ( msg.message==WM_KEYUP ) { int nVirtKey = (int) msg.wParam; // if the user pressed the ESCAPE key, then // print the text the user entered and quit if ( nVirtKey==VK_ESCAPE ) { // get the edit control HWND hEdit = ::GetDlgItem(hWnd,IDC_EDIT1); if ( hEdit ) { // get the input text the user entered // and print it to the console window char pText[3201]; int nSize = ::GetWindowText( hEdit, pText, 3200 ); pText[nSize] = 0; printf("/nYou have entered the "); printf("following text in a second "); printf("thread:/n/n%s/n/n",pText); } else { printf("Failed to get edit control/n"); } // destroy the dialog and get out of // the message loop ::DestroyWindow(hWnd); bDone = true; break; } } // process message ::TranslateMessage(&msg); ::DispatchMessage(&msg); } else { // if there is no message to process, // then sleep for a while to avoid burning // too much CPU cycles ::Sleep(100); } } } int _tmain(int argc, _TCHAR* argv[]){printf("Hello, world of console apps/n"); // create a new thread to allow user input if( _beginthread(InputThreadProc, 0, NULL )==-1) { printf("Failed to create thread"); return 0; } // wait for the new thread to finish while ( !bDone ) { // sleep 3 seonds ::Sleep(3000); printf("main thread running/n"); } return 0;}

 

一些说明
1. 需要多线程库支持
#define _MT

请看如下MSDN上关于 /MT和_MT的解释
/MT
Causes your application to use the multithread, static version of the run-time library. Defines _MT and causes the compiler to place the library name LIBCMT.lib into the .obj file so that the linker will use LIBCMT.lib to resolve external symbols.

2. 创建窗口
HWND hWnd = ::CreateDialog(NULL,MAKEINTRESOURCE(IDD_DIALOG1),NULL,NULL);
if ( hWnd!=NULL )
    {
        // show dialog
        ::ShowWindow(hWnd,SW_SHOW);
    }
创建对话框， 使用VS资源编辑器创建一个对话框， ID=IDD_DIALOG1

3. 接收和处理消息
MSG msg;
while(1)  {
::PeekMessage(&msg, hWnd, 0, 0, PM_REMOVE)
}
PeekMessage: Dispatches incoming sent messages, checks the thread message queue for a posted message, and retrieves the message (if any exist).

 

******************************************************************************

不用对话框, 用常规方法创建窗口.

1. 定义窗口, 注册窗口, 注意这里在定义窗口时, 使用了默认的消息处理函数  wndclass.lpfnWndProc   = DefWindowProc ;

2. 创建窗口

3. 显示, 更新窗口

4. 消息循环

void ThreadTwo(void* dummy){static TCHAR szAppName[] = TEXT ("SysMets1") ; HWND hwnd ; MSG msg ; WNDCLASS wndclass ;int iCmdShow=1;HINSTANCE hInstance = NULL; //GetModuleHandle(NULL); wndclass.style = CS_HREDRAW | CS_VREDRAW ; wndclass.lpfnWndProc = DefWindowProc ; 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; } hwnd = CreateWindow (szAppName, TEXT ("Get System Metrics No. 1"), WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL) ; ShowWindow (hwnd, iCmdShow) ; UpdateWindow (hwnd) ; while (GetMessage (&msg, NULL, 0, 0)) { TranslateMessage (&msg) ; DispatchMessage (&msg) ; } return ; //msg.wParam ;}
