Problem trying to call a form

Anonymous — Tue, 08 Mar 2011 21:14:00 GMT

I get the following error when I try to call a form using ShowModalDialog(MyForm):

Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I've tried different syntax. I've even rebuilt my project from scrap (because this is a conversion of a VBA module... it had a sloppy start). Nothing helps.

I've never had so many problems trying to program anything in the last 30 years as I have run into with AutoCAD's .Net API.

If I wasn't already bald, I would be tearing my hair out!

Please, help me or shoot me. Either choice would be a relief at this point.

Is your form on a network server? That looks like a code access security message. Search here for CASPOL or move the form to a local drive.

That was, indeed, the problem. I moved the source from my area on the server (which is backed up) to my local drive (which isn't backed up), and I got past that error. Other errors came up, but it's early in the debugging process and hopefully they will all be 'normal' errors.

Thanks for the help!

Now, if only Microsoft had all their error messages make a bit more sense..... <sigh>
