inherited user control

[Mihai]

Hi !

I use VB.Net 2005.
I created an inherited user control based on a previosly created user
control.Everything is Ok . I can run this control with f5, everything is
fine. When I close Visual Studio and a open it again and load my project I
have the error:

One or more errors encountered while loading the designer. The errors
are listed below. Some errors can be fixed by rebuilding your project, while
others may require code changes.

Unable to load one or more of the requested types. Retrieve the
LoaderExceptions property for more information.

I rebuid the project but no effect and I cannot load this inherited user
control. I cannot even see it .
Any ideas please why is happening ?

Are you performing any operations in the load event? Especially, things that
might error, like db access? If you are, are they surounded with code that
looks like:

If Not Me.DesignMode Then
' Do Cool Stuff
End If

?

Now I have this error for the same scenario :

Could not load file or assembly 'BaseControls, Version=1.0.2560.40871,
Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system
cannot find the file specified.":"BaseControls, Version=1.0.2560.40871,
Culture=neutral, PublicKeyToken=null"}

This project BaseControls is in the same assemblies as with the others !

Why Visual Studio cannot find this file ?

Any ideas ?
