Hi,
I want to create a setup project such that I can programatically install my user controls to the toolbox.

I tried the following code:

System.Type t = System.Type.GetTypeFromProgID("VisualStudio.DTE.9.0");
object obj = System.Activator.CreateInstance(t, true);
dteObject = (EnvDTE.DTE)obj;
ToolBoxWnd = dteObject.Windows.Item(EnvDTE.Constants.vsWindowKindToolbox);
tlbTabs = ((ToolBox)ToolBoxWnd.Object).ToolBoxTabs;
tlbTab = null;
tlbTab = tlbTabs.Add("TAB1");
ToolBoxWnd.Visible = true;
ToolBoxWnd.DTE.ExecuteCommand("View.PropertiesWindow", "");
tlbTab.Activate();
tlbTab.ToolBoxItems.Item(1).Select();
tlbTab.ToolBoxItems.Add("TAB1",@"C:\DLL\Synchronize.dll", vsToolBoxItemFormat.vsToolBoxItemFormatDotNETComponent);
MessageBox.Show("TAB1" + " Succesfully added to ToolBox.", "Add/Remove", MessageBoxButtons.OK, MessageBoxIcon.Information);

the issue i am facing here is that only the tab is getting added and not the controls to the toolbox :( I donno wats the issue here too??

Can anyone please figure out what am I missing here ....is there anything specific to the dll which I should do to get them added to the toolbox??
Is there any other way by which I can programatically add user controls to the toolbox? Urgent need ...Please help
Thanks in advance
