How to use the control:
Load items using the AddItem method; you can specify an additional Tag to each item (for example you can specify an item picture)
Then manage the OnOwnerDraw event and set images to items when needed.
Example:
On the Form_Load event:
With ctlUniComboImageXP1
.AddItem "aaaa", , pic1.picture
.AddItem "bbbbbb", , pic2.picture
.AddItem "cccc"
End With
On the OnOwnerDraw event:
'If a tag has been specified
if (ctlUniComboImageXP1.ListTag(lItemIndex)<>"") Then
Set oItemPic = ctlUniComboImageXP1.ListTagObject(lItemIndex)
End If |
