Just one more quick question as to how can I call the same code again; since the Click button is on a different form?

Make the PopulateTreeView method static and alter the parameter list so that it accepts an instance of frmMain (to access the TreeView, StatusBar, etc.)
.

class frmMain
{
   ...
   public PopulateTreeView()
   {
      // fill the tree view here.
   }
}

// In your other class, you can call it like this:
frmMain mainInstance = new frmMain();
frmMain.PopulateTreeView();
