Control with C# the RSLinx DTL32.dll

Volker · Jan 14, 2009

We want to control with C# the RSLinx DTL32.dll.

I have problems with the DTL_READ_W and DTL_READ_W functions of the RSlinx software (DTL32.dll).
The error messages receive is DTL_E_BADID, Define ID out of range.
I think I made an error in the definition of the function parameters in C#.
Please can somebody look at the attached code and the output window and give us some tips.
Maybe somebody has an C# example.

Thank you , Best regards
Volker

Hi,

It's a long time since you asked your question and I am using a newer version of dtl, but the problem may that the name_id in the DTL_C_DEFINE is supposed to be an int.

Control with C# the RSLinx DTL32.dll
