I had a working program (Windows Forms Project) complete with buttons, labels, textboxes e.t.c. and the underlying code.
我有一个工作程序（Windows窗体项目），包括按钮，标签，文本框e.t.c.和底层代码。
In an attempt to shortcut my work, I decided to add tab controls and move everything in my main form into tab 1 (cut and pasted). As you can imagine it didn't work. I then got rid of the tab conrol and pasted everything back into the main form but the program doesn't work anymore. Can someone tell me what's wrong please?
为了简化我的工作，我决定添加选项卡控件并将主窗体中的所有内容移动到选项卡1（剪切和粘贴）。你可以想象它没有用。然后，我删除了选项卡控件并将所有内容粘贴回主窗体，但程序不再起作用。有人可以告诉我有什么问题吗？
I'm working in MS V studio 2008 express Thanks.

The event handlers that you coded are still there. However, they are not associated with the control any more. I'm not sure if you're using VB.Net or C#, but the fix is the same - it's manual and tedious if you have a bunch of controls, but not too difficult. Here are the instructions for fixing a single button control, and you'll have to apply the concepts across the board.
您编码的事件处理程序仍然存在。但是，它们不再与控件相关联。我不确定你是使用VB.Net还是C＃，但修复方法是一样的 - 如果你有一堆控件，这是手动和乏味的，但并不太难。以下是修复单个按钮控件的说明，您必须全面应用这些概念。
These instructions are specific to C#. I can give you VB instructions as well as I've done this plenty of times.
这些说明特定于C＃。我可以给你VB指令以及我已经做了很多次。
Double click on the button to generate a new event handler. If the button is named Button1, the original event handler was probably called Button1_Click. Now it should be Button1_Click1.
双击该按钮以生成新的事件处理程序。如果按钮名为Button1，则原始事件处理程序可能称为Button1_Click。现在它应该是Button1_Click1。
Delete the Button1_Click1 function and compile. You'll get errors and if you doible-click on the error in the error pane it will take you to the form,designer.cs file to a line that looks like:
删除Button1_Click1函数并编译。您将收到错误，如果您在错误窗格中单击错误，则会将表单designer.cs文件转到以下行：
this.Button1.Click += new System.EventHandler(this.Button1_Click1);
Change this to
将此更改为
this.Button1.Click += new System.EventHandler(this.Button1_Click);
to point to the previously existing event handler, and the event handler will be fixed.
指向先前存在的事件处理程序，并修复事件处理程序。

I have done this many times, but I usually just drag them into the TabControl. Maybe in the cut and paste operation your controls have become unwired from the event declarations.
我已经做了很多次，但我通常只是将它们拖到TabControl中。也许在剪切和粘贴操作中，您的控件已从事件声明中取消连接。

Possibly some of the events had code lost. If you do it again it will probably work. For an alternative method see my message
可能有些事件丢失了代码。如果你再做一次它可能会有效。有关替代方法，请参阅我的消息
