Hello minhtri ...
it is good to put your program setting in a windows registry or you can put it in a TextFiles or Dat files.
VB give Save Setting and Get Setting method that all setting you made will be put in a VBA key in registry that
VB create when you install the software ( the method search the key automatically ). The problems is, if user computer didn't installing the
VB ???. my suggestion is, you can make it the key by your own use REG_CREATE_KEY and all the friends, you can find it in API Viewer to load the function in your programs, you can put the key anywhere in a registry just depends on how you call it later. That's all from me, hope this can help you to solve the problems, have fun with your scripts friends . . .bye
