.NET framework 1.0

[karenina]

Hello there.

I am trying to develop a AutoCAD 2005 plugin using .NET framework 1.0 (C#). I am encountering some problems with the speed of my window forms (in a normal Windows application, everything is fine, but when using under AutoCAD, they are very very slow).
Is there any way I can solve this problem?
I cannot use 1.1, since it is a huge application and it is not my decision to take, so I have to find some way to solve the problem.

I tried telling AutoCAD through the config file that he must use v 1.0, but no improvements.

Any ideas?

Thanks a lot.

Are you referring to the first time the form shows or every time?

There will be a hit when the first dotnet code is run as the framework has to be loaded. You can see the same slowdown running the layer command for the first time in a new session.

I have a lot of dotnet forms in ADT/Autocad2005 and have no problems with speed versus a standalone .exe.

Not only the first time, but all the time. My problem is actually more complex, since my plugin must log on to a server (which is also connected to a database). I have to get objects from the serverand show them to the user. I believe the low performance is because of the remoting connection with the server.

I am using the exact same window forms in the exact same way in an Windows Form Application and everything works fine.

Do you have any idea about this behaviour?

Thanks a lot for your quick answer.

That should not be the case, code running from a dotnet dll should execute exactly as fast in Acad.exe or your own .exe.

There is something defintely funky going on, I use a database as well, but I am using disconnected recordsts. My database size is small enough that reading it into a dataset is not a problem.

I would suggest trying to narrow it down to a simple sample that can be sent to autodesk for analysis.

E.G. Create a .dll that shows the slowdown in acad.exe and also create an exe using the same .dll with no slowdown.
