LOL. The CreatePDF procedure below successfully creates a my PDF. It also
hooks up the table event but couldn't make it further than tat.
.... Dim myevent As New PdfPTableEvents
my_pdf_tbl.setTableEvent(myevent)
MyEventhandler does not work however. I just want to iterate over each row and
column to get the text and the x,y cords.
The task I have is not much more difficult than that. Inside the Event handler
I want to
get the coordinates of text as well as write text to other file formats. These
other formats are not priorities so I am laying the groundwork
for being able to quickly convert from PDF to these other file formats.
As far as technique, TableLayouts it is the recommended and easiest way to
accomplish this according to the examples in the ItextSharp exercises on
Sourceforge. It seems to be manageable. But the example does so much with
colors and rotations and all, I can't pick out the exact code I need. So
example would be appreciated.
Thanks for quick responses.
