Good evening Chris:
Responding directly I want to preview a file created from my application.
When I make such a billing daily (list) instead of having to print want to pre-visualize the listing on the screen and then then print if you want.
I have looked and found that there is DocumentViewer function that does what I want.
Now the question is what I have to do to generate the file (listing) to preview it.
I think I could clarify what I try.
Thanks again
