It's working in my FB II program so I know it does work with FB II. I don't know about FB3. Don't know which FB you're using. 2. Make sure the RdWr resources are in your resource file. Those should have been added by the RdWr installer. 3. You need the Utilities.GLBL and RdWrUtilities.FLTR files in your project. Mine looks like this: ' my globals are here GLOBALS "Utilities.GLBL" END GLOBALS INCLUDE "RdWrUtilities.FLTR" 4. What I did was instead of using FN RdWrAddTypes(gopenTypes$) is hardcoded my file types in by using gopenTypes$ = "PNTGPICTSCRNCSCRSPn3GIFfJPEG" and then handled the ones that didn't come with the filter on my own. If you still have trouble, I can probably send a working sample. Al Staffieri Jr. AlStaff@... http://members.aol.com/AlStaff/index.html
