how can i call dll with lvrefnum *image from vb6.

i created a dll as in the attachment and i want to use this dll in vb6. This code gets an image from "d:\a.jpg" directory and displays the image in grayscale.  Can you send me a sample code as an addition?

Assuming that you don't need to do anything with that pointer aside from pass it around, you can declare that parameter as a "ByVal Long image" in your declaration.  Declare a variable (as a Long) to pass in to the image parameter.
