程序代码：

int main()
{
    HWND   hWorker,hRebar,hComEx,hcom,hEdit;   
    HWND   hwndParent=::FindWindow(L"IEFrame",NULL);//找到最近的IE，要是找到某个IE需要枚举所有的IE过筛子   
    if(hwndParent   ==   NULL)//没有IE运行中   
        return   FALSE;   
    char   szURL[260];  
    memset(szURL, 0, 260);
    hWorker=FindWindowEx(hwndParent,0,L"WorkerA",NULL);//找到工作区   
    if(hWorker   ==   NULL)//用户用NT   
        hWorker=FindWindowEx(hwndParent,0L,L"WorkerW",NULL);//WindowNT中的ie   

    hRebar=FindWindowEx(hWorker,0,L"ReBarWindow32",NULL);//找到Rebar   

    hComEx=FindWindowEx(hRebar,0,L"ComboBoxEx32",NULL);//找到Comboboxex   
    hcom=FindWindowEx(hComEx,0,L"ComboBox",NULL);//找到combobox   

    hEdit=FindWindowEx(hcom,0,L"Edit",NULL);//找到ComBoBox的edit控件句柄   


    ::SendMessage(hEdit,WM_GETTEXT,260,(LPARAM)   szURL);   

    AfxMessageBox((LPCTSTR)szURL);   
    return   TRUE;   
//    cout << szError <<endl;
