MFC中如何获取按钮控件的尺寸

MFC中如何获取按钮控件的尺寸，望各位VC达人们能告诉我，谢谢！

CRect rectTemp;
GetDlgItem(IDC_BUTTON1)->GetWindowRect(rectTemp);

cwnd::getcurrentmessage 

static const msg* pascal getcurrentmessage( );

return value

returns a pointer to the msg structure that contains the message the window is currently processing. should only be called when in an onmessage handler.

你应该是多个按钮共享clicked事件的处理函数吧？调用下面语句获取当前响应on_clicked消息的控件id:

word id=loword(getcurrentmessage()->wparam);
