OPC server(or DDE server) data reading

Greetings,

I`m using analog signal PC data logger with special software for data collecting/analysis and in this software is available OPC(or DDE) support for recording external data.

In the software for OPC server first channel ONLINE path looks like this:

\\my_pc\\TEST.ONLINE.C_1


...or for DDE server first channel ONLINE path look like this:

\\my_pc\EVDDESERVER|TEST!ONLINE.C_1

(DDE server channel reading value is possible to display in the EXCEL cell and it looks like this "=EVDDESERVER|TEST!ONLINE.C_1")


And the question is: how to make in VB form textboxes to display/read/show this signal ONLINE value from OPC server(or DDE server)?

Thanks in advance.
