Has anyone successfully worked with the toolbox in the VS.NET IDE? It seems that all the information you can get from the EnvDTE object model is the name of a toolbox item, but not it's parent class or containing .DLL. This code, swiped shamelessly from a VB.NET sample and turned into C# seems to work OK for getting the names of the things in the toolbox:

private void myButton2_Click(object sender, System.EventArgs e)
{
// Get an instance of the currently running Visual Studio .NET IDE.
EnvDTE.DTE DTE;
DTE = (EnvDTE.DTE)System.Runtime.InteropServices.Marshal.GetActiveObject("VisualStudio.DTE.7.1");
//Define the variables and create an object reference to the IDE's
//ToolBox object.
EnvDTE.Window win = DTE.Windows.Item(EnvDTE.Constants.vsWindowKindToolbox);
EnvDTE.ToolBox objToolbox = (EnvDTE.ToolBox)win.Object;
EnvDTE.ToolBoxTabs colTbxTabs = objToolbox.ToolBoxTabs;

EnvDTE.ToolBoxTab ActiveTab = objToolbox.ActiveTab;

//Now you can manipulate the ToolBox.
//List the total number of tabs in the ToolBox.
string ToolBoxTabs = "";
foreach (EnvDTE.ToolBoxTab tabs in colTbxTabs)
{
if (ActiveTab.Name == tabs.Name)
{
ToolBoxTabs += "* " + tabs.Name + "\n";
foreach (EnvDTE.ToolBoxItem items in tabs.ToolBoxItems)
{
ToolBoxTabs += " -" + items.Name + "\n";
}
}
else
{
ToolBoxTabs += tabs.Name + "\n";
}
}
MessageBox.Show(ToolBoxTabs);
}

I'd like to build a tool to subclass all classes in a toolbox tab. So far, no luck working with the binary toolbox.tbd file either <g>.

Thanks,
Mike
