Brad Pane #3 / 4	Combo Box - no2 dropdown list problem If the ComboBox style is set to DropDownList type, then you can either add the items at design time using the "List" property, or at run-time using the cboCertificate.Additem method. To set the DropDownList to a "BLank" set the cboCertificate.ListIndex = -1. Setting a DropDownList type combo using a code statement like cboCertificate.Text = "" will most likely cause an error, which if not trapped could cause your runtime to crash. You can set the DropDownList box by setting the text property = "PG", or any of your already added items, as long as the word has already been added to the list. If you are using a ComboBox then you can set the Text property without using "AddItem" first however it does not actually get put into the list until it is added.

Phillip War #4 / 4	Combo Box - no2 dropdown list problem Andrew, Check out the Style Property - if it's set to "2 - Dropdown List", then you can only select from values already in the list (by setting the ListIndex property); you can't assign values directly to the Text property. Having said that, you can 'blank' out the ComboBox temporarily by setting the ListIndex to -1. Regards, Phill W.
