Our moderator has split your post to a new thread.
In general, unless you are providing an answer to a post, we prefer that you create a new thread, even if the question appears related to an old question.

In LEADTOOLS v17.5 OCR we don't have direct support or programming interface for VB6.
If you want to use VB6, you can try to use LEADTOOLS C DLL functions with VB6. The following forum post contains useful information about using LEADTOOLS v17.5 CDLL (API) functions with VB 6.0:
