When pbvm170.dll is missing I get an error message (dll missing).

Now I tried the JsonGenerator feature of PB2017R3 but forgot to deploy the pbjson170.dll. I got no error message but every call to JsonGenerator returned -1. Why do I get no corresponding error message?

A worse behavior occurs when I call HttpClient.SendRequest without deploying pbhttpclient170.dll. No error at all but a very strange behavior of the application, obviously it never leaves the SendRequest function.

I would prefer an error message in all those cases (xxx.dll missing).

Kind regards
Bernhard

Hi Bernhard;

  Interesting ... the SendRequest command should have returned a  "-1" code in that case. If not, please open a support ticket for this issue.

  The JSONGenerator "-1" seems OK to me. I would rather a command fail silently with a proper indicator. However, in both these "-1" cases, I think that the PB Help file should also state that a "-1" could be the result of a missing DLL (and name the DLL in the Help).

Regards ... Chris

The SendRequest() returns NULL instead of -1.
