Hi, iam using visual studio 2008 and when iam using VB.net and i try to add a user control to the toolbox which is fine. i can use this control and nothing is wrong with it but when i build or re-build the project, it creates multiple instences of the same control in the toolbox(basicly the controls are cloning themselfs) after a while i might have 15 usercontrols in the toolbox and it becomes cluttered with copys.Anyone heard of this before? | | axel11 Friday, September 11, 2009 1:29 PM | Hi Axel11, how do you add the user control to the toolbox? Could you show your code?
I guess you should not manually add it.

| | John Chen MS Friday, September 11, 2009 2:57 PM | Please Add a Panel to your form and then add your user control to the Panel in this way.
Dim myControl1 As New MyControl1()
Me.panel1.Controls.Add(myControl1)
MyContorl1 is your user control.
you can remove it from the Panel in this way.
If Me.panel1.Controls.Count > 0 Then
Me.panel1.Controls.RemoveAt(0)
End If
Since only one control is shown at a time, so you just need to removeat index 0.
Each time you can clean the panel and then add a control to it.
and here are a sample about it

| | Xingwei Hu Thursday, September 17, 2009 2:58 AM | Xingwei,
I am experiencing the same issue that Axel11 had, except that in my case, the multiple instances of toolbox items were created when I ran the Power Pack Installer (VisualBasicPowerPacks3Setup.exe). Before installation, my toolbox was "normal". After installation, I clicked on the Power Pack group and saw a list containing 20 or more items called "PrintForm". Further, those items were the only items in the group, and the one I was interested in (Data Repeater Control) was not in the list.
I instinctively uninstalled the Power Pack, which removed not only the Power Pack group from the Toolbox, but everything else as well. Now, there is only a group named "#13199" in the toolbox, and I have no other items for selectable user controls.

Afterward I right clicked on the toolbox pane and selected "show all", and it fixed the problem. Now, all the power pack options are displayed, as well as the original items (plus some). Hope this helps.
