Good morning,

I just completed creating my first custom server control and am trying to add it to the toolbox. My question/problem is when I browse to where the DLL is located on the server and click Add, it is adding almost two identical entries. One has the namespace listed and the other has a blank namespace in the Customize Toolbox dialog box.

When I try to drag and drop the control without the namespace listed I get an error.

Any ideas why these two entries are being added each time I add a new control?

Thanks in advance.

Do they both have the same version number also? Check on that...

Yes... both controls are exactly the same minus the namespace being empty on one of them. I click on the DLL to add it and both appear in the customize toolbar dialog. Both version numbers of 0.0.0.0 (retail)

Here is the command line I used:
vbc /t:library /r:System.dll,System.Web.dll ColorAccessor.vb

and here is the code from the VB file:
Imports System.ComponentModel
Imports System
Imports System.Web
Imports System.Web.UI

<DefaultProperty("Text"), ToolboxData("<{0}:ColorAccessor runat=server></{0}:ColorAccessor>")> Public Class ColorAccessor
    Inherits System.Web.UI.WebControls.WebControl

    Dim _text As String

    <Bindable(True), Category("Appearance"), DefaultValue("")> Property [Text]() As String
        Get
            Return _text
        End Get

        Set(ByVal Value As String)
            _text = Value
        End Set
    End Property

    Protected Overrides Sub Render(ByVal output As System.Web.UI.HtmlTextWriter)
        output.Write([Text])
    End Sub

End Class

Namespace dbControls
    Public Class ColorAccessor : Inherits Control
        Private _text As String
        Private _color As String

        Public Property Text() As String
            Get
                Return _text
            End Get
            Set(ByVal Value As String)
                If Value <> "Good afternoon Ethan" Then
                    Throw New ArgumentException("You must enter Good Afternoon Ethan")
                Else
                    _text = Value
                End If
            End Set
        End Property

        Public Property Color() As String
            Get
                Return _color
            End Get
            Set(ByVal Value As String)
                _color = Value
            End Set
        End Property

        Protected Overrides Sub Render(ByVal output As HtmlTextWriter)
            output.AddAttribute("color", _color)
            output.RenderBeginTag("font")
            output.Write(_text)
            output.RenderEndTag()
        End Sub
    End Class
End Namespace

Thanks for the help.

I don't see what the problem is; the two classes declared above has the namespace declared for one and no namespace for the other... Is there an assembly switch for the vbc compiler where you can specify the assembly these controls are in? I'm not familiar with the vbc compiler.

I dont think so.. but then again I am fairly new to .Net. I am following examples in a book I have and the end result is the two additions to the toolbox.
