.Net MDI Aware

[mbujak]

How do I make a .net application MDI aware. In ObjectArx, acrxRegisterAppMDIAware(...) is used. Is there an equivalent method in .Net? I am using VS 2010 for AutoCad 2012. Any ideas?

All .NET applications are MDI aware, so there is no need to notify AutoCAD to that effect.

Thanks Owen. After you have replied, I thought it must be something else so I checked the SDI setting in Autocad and it was set to (1). I set it manually to (0) and all works fine. Is there a way to set this variable value in .net to ensure MDI awareness?

You can add code to your application that checks SDI at load time and refuses to run when SDI is set to 1, but you can't (and shouldn't even if you could) reliably switch SDI mode.
