Hi,

Which powerbuilder version? 32 bit or 64 bit?

How was the DLL compiled ( .Net Framework, .Net core xx) ? 32 bit or 64 bit?

Can you post / attach you DLL so we can try?

regards.

Hi J;

Only "simple" data types can be passed between PB & .Net modules. You cannot pass object classes as neither PB or .Net can understand each other's classes.

Regards.... Chris

Jeganathan, since the SqlConnection object is an argument, the .NET DLL Importer requires it to be defined in order to load the function's signature.

One solution is to include the corresponding assembly alongside the DLL you're trying to import.
