Custom dialog in a class library

[bergerkiller]

And can you actually use a windows form in the solution list?

And when using the methode mentioned by cicatrix, can I just add event handlers and others in the MyCustomForm class?

Thanks for the help so far

EDIT:

I tried using:

Class MyClassLib

     Class MyCustomForm
         Inherits Windows.Forms.Form
         ' Your corm logic here
         ' Don't forget to move all your designer code here as well.
     End Class
     
     Public Function ShowDialog() As DialogResult
         Dim f As New MyCustomForm
         Return f.ShowDialog
     End Function
End Class

And exported it as a library dll.
I made a reference to it in my test application, but now it can't find the subs and functions.
Here is my code:

Public Class TextureBrowseDialog
    Public Function ShowDialog() As Windows.Forms.DialogResult
        Dim f As New Form1
        Return f.ShowDialog
    End Function

    Public Function GetTexturePath() As String
        Return TextureBrowserSelTexture
    End Function
    Public Function GetTextureImage() As Drawing.Image
        Return TextureBrowserImageTexture
    End Function
    Public Sub SetRoot(ByVal RootPath As String)
        TextureBrowserRoot = RootPath
    End Sub
    Public Sub SetTexturePath(ByVal SelectedPath As String)
        'TODO
    End Sub

End Class

Anyone knows why it can't find the public subs in this class?
(it did with a previous library...)
