Hi from Germany,

I have to update some OPC samples, written in C# and Visual Basic for .Net.

These older .Net samples, using OPC DA, are compiled for x86 and they are running with the following DLL:

opcrcw.da.dll (Version 3.0.101.0, Description: OPC Data Access 3.00 .NET Wrapper)

The opcrcw.da.dll is a 32 bit DLL.

The task is to compile the samples for x64 (or AnyCPU).

Question:
Is the opcrcw.da.dll available for 64 bit?

If yes, where?

Thanks a lot,

Carsten

You need to upgrade.
