Hi Jody,
Could you post some code ?
Regards,
Fergus
The code is at the end of this message.
I have a collection of forms that have been selected to be printed. Within
each form, there can be either 1 or 2 pages. The user also has the option
to select which pages of each form are to be printed through a treeview
control. The "PrintToGDI P" procedure is called which in turn sets up the
print job. The procedure that does the printing is under
"PrintPage_Even t_PDF" which is setup using the "AddHandler " call. The line
of code within "PrintPage_Even t_PDF" that determines if a page should be
printed is:
If strPages.IndexO f(m_intPrintPag e + 1) > -1 Then
"strPages" contains a comma-separated list of the pages to be printed (ie.
"1,2" or "1" or "2") based on user selection.
After thinking about this over the weekend, it would be easier for me to
create an array of pages from each form that are to be printed before
"PrintPageEvent _PDF" is called. This way, all pages are determined before
printing and all I will have to do afterwards is cycle through the array
instead of doing validation on each form within the print code. Regardless,
it would still be nice to know if it is my code causing the blank pages to
be printed, or if it is some type of bug within the .NET Framework
(v1.0.3705).
Thanks,
Jody
