Hello all,


i want to use different ORCA-versions (105, 125, 170, 190) in C#. I Installed the newest Powerbuilder Versions and did a [DllImport("PBORC...")] with each version.


But in the end, i could not use the 12.5 and 19.0 version because the dll`s are not registered. I did a little research and i think the problem is that orca version 12.5 and 19.0 are not in the C:\Program Files (x86)\Appeon\Shared\PowerBuilder directory. I also discovered that the 19.0 version does not have a PBORC190.dll, the name is PBORC.dll...

I also tried to register the dll manually like this:

regsvr32 "C:\Program Files (x86)\Appeon\Shared\PowerBuilder\PBORC190.DLL"

For the version 19.0, i renamed and moved the dlll to the shared folder.



Is there any workaround to use the 12.5 and 19.0 orca versions???

Registering a DLL is only needed if it has a COM interface. As long as the folder is in the system path, it should be able to find it.

With PB 2019-R3 and PB 2021, the runtime folders aren't added to the system path.

The application runtime files are in:

C:\Program Files (x86)\Appeon\Common\PowerBuilder\Runtime ?????

The IDE files (including PBORC.DLL) are in:

C:\Program Files (x86)\Appeon\PowerBuilder ??.0\IDE

The current runtime folder can be found in the registry:

HKEY_CURRENT_USER\SOFTWARE\Sybase\PowerBuilder\??.0  -  CurrentRuntimeVersion

Your app can update the system path for the current process using GetEnvironmentVariable and SetEnvironmentVariable.

ive added the C:\Program Files (x86)\Appeon\PowerBuilder 19.0\IDE to the system path variables and tried to acces the PBORC.dll via C#. It shows me again that the dll couldn't be found....

Did you also add the runtime folder to the path?
