A DropDownPictureListBox control is similar to a DropDownListBox, but with the addition of pictures associated with the items in the list.
The pictures used in this control can be bitmaps (BMP file), icons (ICO file), cursors (CUR file), GIF (but not animated GIF) files, or JPEG files.
Making the list display
In the development environment, if the list portion of the DropDownPictureListBox
is not displayed because ShowList is set to FALSE, the
user must click the down arrow at the end of the text box to display
it.
