[anand]

Hi friends i am getting an error while creating the .dll for a component in vb.net....

Inherits System.ComponentModel.icontainer is not defined...

 

my code is:

 

Imports System
Imports System.Data
Imports System.ComponentModel.Component
Public Class Component1
   Inherits System.ComponentModel.Component
   Public Function func() As String
       func = "func from component1"
   End Function
#Region " Component Designer generated code "

   Public Sub New(ByVal Container As System.ComponentModel.IContainer)
       MyClass.New()

       'Required for Windows.Forms Class Composition Designer support
       Container.Add(Me)
   End Sub

   Public Sub New()
       MyBase.New()

       'This call is required by the Component Designer.
       InitializeComponent()

       'Add any initialization after the InitializeComponent() call

   End Sub

   'Component overrides dispose to clean up the component list.
   Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
       If disposing Then
           If Not (components Is Nothing) Then
               components.Dispose()
           End If
       End If
       MyBase.Dispose(disposing)
   End Sub

   'Required by the Component Designer
   Private components As System.ComponentModel.IContainer

   'NOTE: The following procedure is required by the Component Designer
   'It can be modified using the Component Designer.
   'Do not modify it using the code editor.
   <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()

This line:

 

Imports System.ComponentModel.Component

 

Should not be there.

You need to tell the compiler that you're referencing the System.dll and System.Data.dll assemblies:

 

C:\>vbc /target:library component1.vb /reference:System.dll /reference:System.Data.dll

Hi Divil

I Have a small doubt now..

i created a .dll for a component and i created a strong name for that(comp1.snk) and i add that .snk file to my application ..and i write the line <assembly:assemblykeyfile("comp1.snk")>

i biuld my application..it didnt give any error..............

 

 

but when i am trying to add that .dll into global assembly cache its giving the error

 

C:\ANAND\DLLS>gacutil /i comp1.dll

 

Microsoft ® .NET Global Assembly Cache Utility. Version 1.0.3705.0

Copyright © Microsoft Corporation 1998-2001. All rights reserved.

 

Failure adding assembly to the cache: Attempt to install an assembly without a strong name

 

 

pls give me a idea how to add my dll to GAC...

Thank you

[divil]

To give your assembly a strong name, you need to use the /keyfile:mykeyfile.sn parameter. This is all in the Framework SDK documentation.

hi divil

already i ceated a strong name to my assembly...i want to register that in global assembly cache...pls give me a idea how to do that...

Thank you
