Hello Jothis,

to clear even the actual selection of a combobox you can use this undocumented "feature":

ComboBox2.Clear
ComboBox2.Text = ""

The .Text is not provided by the syntax help so you have to type it in manually.

I would suggest you to add this line
ComboBox2.SelectedIndex=0
at the end of the
ComboBox1_SelectionChanged
routine.

This selects automatically the first entry in in ComboBox2.

Personally I would also add
ComboBox1.SelectedIndex=0
just before
Form1.Show
in the App_Start routine.
This selects by default the first entry in ComboBox1.

The default selected entries could also be initialised with values from an Init file.

Attached a modified version.

Best regards.
