.NET interop created from ActiveX

xStepa

Hi there,

i need to use an ActiveX dll on NST, so I need to convert it to dotNet. I tried to use tlbimp to convert it and at first it seemed, that I succeed. But NAV throws an error, that .NET framework object cannot be instantiated. All DLLs are on NST and accessible in development client. Has anyone some suggestion?


Thx

Try to set property RunOnClient to Yes for variable AtouchDir.

Hi @lubost, I've tested also this option, but with the same result ...

- Check if your DLL is strongly signed.
- If your code runs on client, you have to copy your DLL to publicly accessible folder (Add-ins folder in client folder is the best) - in that situation should be variable property RunOnClient set to Yes.
- If your code runs on server, you have to copy your DLL to publicly accessible folder (Add-ins folder in server folder is the best) - in that situation should be variable property RunOnClient set to No.

Hi @lubost , thank you for your suggestions.

No, the DLL is not strongly signed, but tlbimp allows this option - but this DLL is used only in codeunit, not as a control on page, so this should not be a problem

Yes, I have also tested this option - I've copied it everywhere.

Yes, the DLLs (.NET and original ActiveX) are on NST and I see them in DEV client.


If you be so kind, you can test it yourself on your server - just try to construct AtouchDirClass ...
Sorry to admins, that I've uploaded it as PDF ...

This is not my practice due to security reason. Sorry
