在应用程序中给自己开发的控件添加选中句柄，我们已实现了，就是用鼠标点击时， 所点的的控件成为活动控件的响应速度慢，点击后，几秒后才成为活动控件（ACTIVECONTROL） ，我在调试时， 用鼠标点 A 控件时，用断点或是日志文件记录，发现活动控件是B，（记录活动的控件的名称）， 不是我所点的A控件， 请问高手，有没有什么办法能使我用鼠标点的控件，立即成为活动控件，成为我程序里的活动控件后，（程序中有取当前的活动控件），然后执行后面的程序代码，好似VB的编辑界面时，窗体中的控件效果，有8句柄能移动，这要在我程序运行时实现，我的程序是，8个句柄（8个小LABEL做的）是共用的，所有的控件都共享这8个，就是在用鼠标选中的控件，我们程序处理是把这8个LABEL放在当前的活动的控件周围，我们遇到的是，我们用鼠标点的，不是当前的活动的控件，所以用鼠标点控件时，我程序是，判断鼠标的位置是否在当前活动控件的矩形内，若是则，8个LABEL到所点的控件周围，8个LABEL到所点的控件周围时间有好几秒，现在是要，用鼠标一点控件，马上8个LABEL就过去，我移动控件程序是用Private Sub Form_DragDrop(Source As Control, X As Single, Y As Single)
Source.left = X - diffx
Source.top = Y - diffy
EightPoints Me 是把8个LABEL放在活动控件的周围
End Sub 我程序是，判断鼠标的位置是否在当前活动控件的矩形内，程序在
Private Sub Form_MouseDown 里，若是则selectcontrol.Drag 1,开始拖动，谢谢高手！！
