I have a .Net 2008 IDE,and my oledbconnection and oledbcommand control is visible but when I am draging it towards component tray it is not coming.
So what is the solution for it.

推荐答案

我在设计器中没有看到这些控件"中的任何一个.我现在正在使用VS2010，并且没有可用的2008，所以我不能肯定地说，但我也不记得它在那里.

I don''t see either of those "controls" in the designer. I''m using VS2010 right now, and don''t have 2008 available to me, so I can''t say for sure, but I don''t remember it being there either.

您编写此控件还是自己控制?因为我从未在工具箱中看到这些.如果这样做了，那可能就是您的问题:您只能将组件放到托盘上，而不能放到控件上.区别在于，控件具有用户界面，并且基于UserControl-组件基于Component，而没有.

这里有一些讨论: MSDN [

Did you write this control or controls yourself? Because I have never seen these in the Toolbox. If you did, that may be your problem: you can only drop Components on the tray, not Controls. The difference is that Controls have a user interface, and are based on UserControl - Components are based on Component and do not.

There is a bit of discussion on it here: MSDN[^]
