关于vb控件拖动！！！！！求教 在线等 急急急！谢谢
我采用如下方法 在form上拖动1个控件Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Declare Function ReleaseCapture Lib "user32" () As Long
Private Const SC_MOVE = &HF010&
Private Const WM_SYSCOMMAND = &H112
Private Const HTCAPTION = 2
ReleaseCapture
Call SendMessage(Command1.hwnd, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0)
请问一下 我现在要实现的是拖动控件1 让控件2跟随移动 有办法吗？
谢谢高人！！！ --------------------编程问答-------------------- 可以结合为组。

能不能说详细点 或者给个代码 万分感谢
--------------------编程问答--------------------
直接用控件的move方法就可以了。不必调用API的 --------------------编程问答-------------------- 抱歉，没仔细看。
你要拖动的话，用drag and drop。也不需要用API的。
具体可查MSDN的VB用户手册里关于拖放那一章。 --------------------编程问答-------------------- 看看drag and drop这方面 --------------------编程问答-------------------- 把要拖放的控件放到picture里，如果不想让用户看出来看到picture里，可以将picture的边框设置为none
然后拖动picture控件即可。

这段代码,未经严格测试,只是本人闲暇时间写的,楼主可以大概看下.
另外VB IDE本身是有示例的. --------------------编程问答--------------------
对，可以放在picture里 --------------------编程问答-------------------- 我在7楼的代码可能不符合你的拖动,那段属于拉伸. --------------------编程问答-------------------- 控件有专门的拖到事件，你可以在被拖动的控件的事件中修改另一个控件的Left和Top属性。即可实现拖动一个控件，另一个控件也跟着移动的效果。 --------------------编程问答--------------------
