VC搜索窗口、遍历子控件

1.得到窗口名

    CString strWindowName;

    strWindowName="xxx";

    //如果搜索word窗口名，则为文件名+“_Microsoft Word”，而且还要注意文件名是否带扩展名

 

2.查找窗口句柄

    HWND hwnd = ::FindWindow(NULL, strWindowName);

 

3.设置窗口位置

    ::SetWindowPos(hwnd,                                      //窗口句柄

                            HWND_TOPMOST,                    //窗口排序

                            x,                                             //左边界坐标

                            y,                                             //上边界坐标

                            cx,                                            //宽

                            cy,                                            //高

                            SWP_SHOWWINDOW );              //窗口显示方式

 

4.激活窗口

    ::SetActveWindow(hwnd);

 

5.遍历窗口内的控件

    ::EnumChildWindows(hwnd,                                         //窗口句柄

                                   (WNDENUMPROC)lpEnumFunc,     //遍历控件回调函数，将窗口内控件的句柄传入lpEnumFunc

                                   NULL);                      

 

 

范例：

 

 

BOOL CALLBACK lpEnumProc(HWND hwnd /*窗口内控件句柄*/, LPARAM lParam)
{

    char* buffer[501]={0};

    LRESULT nRecvNum=0;

 

    if (hwnd == NULL)
        return FALSE;

    if (::IsWindow(hwnd) && ::IsWindowVisible(hwnd) )
    {
        ::GetWindowTextA(hwnd, buffer, 500);         //获得控件上的内容
        if(::GetWindowTextLengthA(hwnd)==0)        //如果控件是editBox，则需要通过发送消息获得
        {
            //length=::SendMessageA(hwnd, WM_GETTEXTLENGTH, 0, 0);
            nRecvNum=::SendMessageA(hwnd,WM_GETTEXT,(WPARAM)500, (LPARAM)buffer);

            if(nRecvNum==0)

                   return FALSE;

        }
    }

    TRACE(buffer);
    return TRUE;
}

 

 

void GetText()

{

    CString strWindowName;

    strWindowName = L"计算器"；

    HWND hwnd = NULL;
    if( (hwnd = ::FindWindowW(NULL, strWindowName )) == NULL )
    {

        printf("Can not find the window");
        return;
    }

    ::SetWindowPos(hwnd,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE|SWP_SHOWWINDOW);  //将窗口置顶

    CenterWindow(hwnd);  //将窗口居中

    ::EnumChildWindows(hwnd,(WNDENUMPROC)lpEnumProc, 0);    //遍历窗口内的控件

}
