Why has my UserControl changed to a Class?

[MotoMan_Yz400]

I've been working on a project that has a few UserControls, all put onto my main form. Recently one of my UserControls has changed into a class (icon in Solution Explorer has changed). I can no longer edit the Designer (GUI) of it. Why has this happened. I first noticed it when I opened the program for edit last, it opened all the window tabs that I was using before (including the GUI designer for that UserControl). When I would double click on an object in that UserControl (in designer mode), it would take me to the Designer text code, not my actual code and everything in my actual code stopped working, and it would only execute subs written in the designer code. What is going on here? How do I get it back?

Thank-you for your help!

Are the <usercontrol name>.Designer.vb and <usercontrol name.resx files still there? Check if they appear in the solution explorer. Usually they should appear underneath the main usercontrol node (if Show All Files is enabled), but sometimes I found it can happen that they get 'detached' and simply show up amongst the other files. When that happens all you need to do is re-add them to your project.

I usually go to the project folder and copy/paste the 3 relevant files (.vb, .Designer.vb and .resx) and paste them to my desktop (or some other temp directory). Then I delete the files from within Visual Studio. Then I use Add - Existing Item to add the three files back. If all goes well they will once again be grouped under the main file in the solution explorer.

@NickThissen - Yes they were under the UserControl that has the issue. I copied/paste them for back-up, then deleted them through the Solution Explorer. I then copy/paste them back into the application directory, and then added them back into the project. No change. I saved the project, then exited VB. I returned back to my project, no change. Not sure if it will help, but I've included the Control.Designer.vb contents. If it means anything, I did call the MusicControl.AxWindowsMediaPlayer1 from other usercontrols and the main form. Maybe a UserControl changing another usercontrol object did it?

            End If
        Finally
            MyBase.Dispose(disposing)
        End Try

The control.resx, reads:
Name: AxWindowsMediaPlay1.OcxState
Type: System.Windows.Forms.AxHost+State
Value: (Value cannot be displayed)


Now, I'm most likely going to re-do this Control anyways (not liking how I have it coded) How-ever I would like to know that I did, so I dont FUBAR another Control.
