关于纯C++ 判断按钮Click事件(按钮是否按下)的问题，如下：

Question

我用的是VC++6.0的环境。
写完一个窗体我在里面放了个按钮用createWindow创的，但是不知道怎么样才可以判断按钮是否被点击，请各位高手们帮帮我。不是MFC，是纯的C++
不好意思我不要MFC的。我要纯的C++的。按钮是用 createwindow创的

Answer 1

按钮在CreateWindow创建，判断是否按下是捕捉WM_COMMAND下面的wParam，按钮ID号，比如：case WM_COMMAND:switch(wParam){case IDC_hBU_View:{FILEVEC vec = GetFies();if( !vec.empty() ){FILEVEC::iterator end = vec.end();for ( FILEVEC::iterator it = vec.begin();it != end;++it ){if( CurSet.end() == std::find( CurSet.begin(),CurSet.end(),*it ) ){CurSet.push_back(*it);//SendMessage( g_hLbFiles,LB_ADDSTRING,0,(LPARAM)it->c_str() );SendMessage( g_hLbFiles,LB_ADDSTRING,0,(LPARAM)DBLib::DBFile::DBGetFileName(it->c_str()).c_str() );int Line = (int)SendMessage( g_hLbFiles,LB_GETCOUNT,0,0 );SendMessage( g_hLbFiles,LB_SETCURSEL,Line-1,0 );SendMessage( g_hLbFiles,LB_SETCURSEL,-1,0 );}}}}break;

API调用，找到窗口句柄调用LRESULT SendMessage(HWND hWnd,UINT Msg,WPARAM wParam,LPARAM lParam);记住一点，按钮是一种特殊化的窗口！

很明显嘛?按钮的点击会向父窗口发送WM_COMMAND消息,捕捉不就行了.例子:// Button1.cpp : Defines the entry point for the application.//#include "stdafx.h"#include "resource.h"#define MAX_LOADSTRING 100// Global Variables:HINSTANCE hInst; // current instanceTCHAR szTitle[MAX_LOADSTRING]; // The title bar textTCHAR szWindowClass[MAX_LOADSTRING]; // The title bar textHWND hWndb; //按钮句柄,一定不能放在消息处理函数中定义.// Foward declarations of functions included in this code module:ATOM MyRegisterClass(HINSTANCE hInstance);BOOL InitInstance(HINSTANCE, int);LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);LRESULT CALLBACK About(HWND, UINT, WPARAM, LPARAM);int APIENTRY WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow){// TODO: Place code here.MSG msg;HACCEL hAccelTable;// Initialize global stringsLoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);LoadString(hInstance, IDC_BUTTON1, szWindowClass, MAX_LOADSTRING);MyRegisterClass(hInstance);// Perform application initialization:if (!InitInstance (hInstance, nCmdShow)){return FALSE;}hAccelTable = LoadAccelerators(hInstance, (LPCTSTR)IDC_BUTTON1);// Main message loop:while (GetMessage(&msg, NULL, 0, 0)){if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)){TranslateMessage(&msg);DispatchMessage(&msg);}}return msg.wParam;}//// FUNCTION: MyRegisterClass()//// PURPOSE: Registers the window class.//// COMMENTS://// This function and its usage is only necessary if you want this code// to be compatible with Win32 systems prior to the 'RegisterClassEx'// function that was added to Windows 95.
