SPY++实例应用-对不知道WindowName的控件的操作

1.利用SYP++查看WIFITRAY程序的主窗口,打开Properties查看Window Caption:WIFI TRAY,ClassName:#32770 (Dialog)

HWND hParWnd = ::FindWindow("#32770","WIFI TRAY");  //查找主窗口的句柄

2.利用SYP++查看WIFITRAY程序的主窗口上的一个Window Caption为空的按钮的Properties,ClassName:Button,Control ID:000003F7;

HWND hButWnd = ::GetDlgItem(hParWnd,0x000003F7); //获取按钮的句柄

3.需要连续发送两个BM_CLICK消息,来实现点击按钮:

 ::SendMessage(hButWnd ,BM_CLICK,0,0);
 ::SendMessage(hButWnd ,BM_CLICK,0,0);
