Discussion

The I directive specifies image used in a tree control. To use images in a tree control, you specify the list of images to use in the format string (i.e. between the % ?.% delimiters in the control definition. When you have multiple directives in a Format string, you separate them with semi-colons ";". Before any entry on a tree that contains an image, add a number, which corresponds to the number of the image in the Image_Choices. If a different bitmap is displayed when a branch of a tree is open, use an optional '+' followed by the number of the image to show when the branch is open. for the open dialog. A Comma should be placed after the prefix image number.
