Hi Jan,
Forget my other posts, they have nothing to do with this one.
"I clearly wrote it's for Update 4. Do you use Update 4? If not, why? "
Simple answer, company PC, no private installation allowed.
Maybe I am wrong but code in my post is Managed API , right?
Correct me if I am wrong but you are saying that Bentley.DgnPlatformNET and Bentley.DgnPlatformNET are COM/Interop API?
Can you, please explain ?
best regards
Nenad
