Hello. I need you to forgive my poor English.
I need to create an OpenOffice Write document with some variables (i.e. LastName, FirstName, Address, etc ...).
Then, I need to send a set of values to replace those variables from a Delphi program.
So far, I've got an OO Write document open from a Delphi program, but I don't know how to bring a set of variable values to it, to obtain a personalized result.
Op. System: Win2k // Delphi Version: 7.0 // OOo Version: 2.4.0

I suppose that it's possible but I don't know the way.
Thanks for your help.
