SUMMARY
To set the foreground and background color of a list box control, set the ForeColor and BackColor properties at either design time or run time. All text in a list box uses the color set by the ForeColor property. The text is printed against a background color set by the BackColor property.

Visual Basic doesn't directly support the display of text of different colors simultaneously in the list box. Multi-color list boxes do not adhere to GUI design standards and should not be used. The Treeview control makes it possible to differentiate list box items, by allowing the use of bitmaps and text on the same line.

This article describes how to display words of different colors simultaneously in a list box by using an indirect technique.



MORE INFORMATION
You can display lines or words of different colors simultaneously in a list box by using the following indirect technique:

Simulate the list box with a picture box control. You can store the desired text strings in an array of strings, and use the Print method to write the array entries into the picture box with different ForeColor properties. For example:

picture1.BackColor = QBColor(14) ' 14=Light yellow picture1.ForeColor = QBColor(4)  '  4=Red picture1.Print "in living red" picture1.ForeColor = QBColor(2)  '  2=Green picture1.Print "in living green"

You can also add a vertical scroll bar next to the picture box. When the scroll bar is scrolled, your code needs to redraw the picture box. The ForeColor property of the picture box controls the current color used by the Print method. The picture box will not let you highlight text. NOTE: The BackColor method erases any pre-existing text on the picture control.
