ComboBox

• Combines TextBox features with a short drop down list.  
  
• ComboBox has three different styles:
• VbComboDropDown – the default style that allow the user to type data directly into the ComboBox as well as select items from the drop down list.  
  
• VbComboSimple – appears as a TextBox with no drop down list.  
  
• VbComboDropDownList – requires the user to select items from the drop down list.  Does not allow the user to enter data directly.

• Some ComboBox Properties:
• ListCount – number of drop-down list items.
• ListIndex – The index of the selected item.  If no item is selected, ListIndex is -1.
• NewIndex – The index of the last item added to the ComboBox.  
  
• To add item to a ComboBox:
• Call cmbCombo.AddItem(txtInput.Text)  
  
• To remove item from a ComboBox:
• Call cmbCombo.RemoveItem(cmbCombo.ListIndex)  
  
• To clear all items in a ComboBox:
• cmbCombo.Clear  
  
• To display an item in the ComboBox:
• cmbCombo.Text = txtInput.Text  
  
• To retrieve an item from a ComboBox:
  • item = cmbCombo.Text

To reset a combo box so that entries are no longer highlighted, first set the list index to 0 and then reset it to -1.

cmbCombo.ListIndex = 0
cmbCombo.ListIndex = -1
