This will show you how to switch to the Tab on the right-hand side of the ShipLinx Main screen (the one marked with a dot):
Globals.FrmMain.tabOptions.SelectedIndex = 4;
This will show you how to change the Font Color (and, hence, you can manipulate the visual items):
Globals.FrmMain.tabOptions.SelectedTab.Controls[0].ForeColor = Color.Red; //change font color on (.) Tab to red
... and how to change the text on that Tab:
Globals.FrmMain.tabOptions.SelectedTab.Controls[0].Text = "Hello there, weary travelers!"; //sets the text of the (.) Tab to say "Hello there, weary travelers!"
