Is it possible to combine Pascal with Visual Basic? At least I would like to read a variable from one language in the other.

A few 2-cent ideas:
- to dialogue via creation\deletion of text file names, names that emulate a rustic protocol.
- if .net supports the SOAP protocol, then it's a way to communicate between 2 programs written in different languages.
use: Linux 64 bits (Ubuntu 18.04 LTS).
Lazarus version: 2.0.4 (svn revision: 62502M) compiled with fpc 3.0.4 - fpDebug \ Dwarf3.

How about external? Can I show my VB form with

Code: Pascal  [Select][+][-]
  1. function ShowForm: boolean; stdcall; external 'C:\...\VB.dll';
  2.  

?

If you mean VB.net, then no, you can't. You need to use one of the points I mentioned.

I suppose one could check to see If the app has any OLE abilities or do what I have done a few times in the
past and that was get the menu handles of the app and send messages to it to trigger the functions..
The only true wisdom is knowing you know nothing

I see. Well, thank you very much guys, the only effective way seems to be COM with OleVariants. I still have issues, but I managed to show my form. I mark this topic as resolved. Special thanks to Dragon.
