    inherited user control

    Hi !

    I use VB.Net 2005.
    I created an inherited user control based on a previosly created user
    control.Everyth ing 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
    LoaderException s property for more information.

      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

      ?

                  Re: inherited user control

                  Now I have this error for the same scenario :

                  Could not load file or assembly 'BaseControls, Version=1.0.256 0.40871,
                  Culture=neutral , PublicKeyToken= null' or one of its dependencies. The system
                  cannot find the file specified.":"Ba seControls, Version=1.0.256 0.40871,
                  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 ?

                  Mihai

                  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
                  ?
