| | Check the value of your [icode]comboBox1.SelectedItem.ToString()[/icode]. My guess it isn't what you think: "*.doc". Have you defaulted the selection before using (eg. SelectedIndex = 0)? Also, you can just use the ComboBox.Text Property to access the selected item's text as displayed in the combobox. |
The End.
