how to include an icon image in AddFolderIcon() of installshield

Where I need to mention the icon 'XX.ico' path in the below method. Right now a icon is created on desktop with some image(XY.ico) corresponding to folder icon Now I need to change that image(XY.ico).开发者_C百科 New image icon has to be place for the same folder icon.

AddFolderIcon (szProgramFolder, szItemName, szCommandLine, szWorkingDir, szIconPath, nIcon, szShortCutKey, REPLACE)

If I follow the question, the szIconPath argument is where you'll want to point to your icon file.
