Control.com - Nerds in Control

I need vb code to read/write a *.stx pl7pro4.1 file. I need this to build a smart editor which can change io numbers without requiring the user to go though the source code & do the find/replace manually.

I wrote a small find/replace code but it works only on sections which i have to import & store as *.ld file and i am not able to read the *.stx file programatically. I went through the pl7 ole server/client code which comes as a sample with the pl7pro software but it does not seem to be of use to me. Any help in this regard will be appreciated.
