PrintPreviewDialog Print Icon not printing

[Randy]

Hello all,
I'm trying to print using PrintPreviewDialog. What's happening is that the
PrintPreviewDialog shows the correct information to be printed, but when I
click the print icon, it prints a blank page. If I comment out the
printPreviewDialog1.ShowDialog();
and just do a
printDocument1.Print();
instead, it prints all the pages like a champ. Anyone know what I'm doing
wrong?
Thanks

Randy,
As I said in my earlier reply you aren't resetting the start of the
print data stream (or wherever you get your print data from). You should
override the OnBeginPrint method of the PrintDocument and set your stream's
staring position back to the beginning there. If you have read through the
stream once already and don't reset the position when you press on the print
button on the PrintPreviewDialog you will already be at the end and thus
have nothing available to print.

Try this print document class. Made it with my new tool.

I did exactly what you said - showed a print dialogue and hit the print
button and it's ok. If you're a VB developer, let me know and I'll reexport
it in VB.
