I'm attempting to write an ActiveX control for InfoPath using C# - which will allow the user to open a worksite folder browser dialog and select a folder.
I've been able to build a forms application which, when run, displays the Worksite Folder Browser Dialog & returns the objectID string if the user selects folder.
I've also been able to construct valid ActiveX controls for use in InfoPath (Test controls have been standard folder browsers, message boxes, text boxes, etc..) after referencing;
http://blogs.msdn.com/infopath/archive/2005/04/15/creating-an-infopath-custom-control-using-c-and-net.aspxhttp://blogs.msdn.com/infopath/archive/2006/12/18/creating-complex-infopath-controls-in-c-sharp.aspxHowever, when I attempt to create an ActiveX\InfoPath component which opens a Worksite folder browser dialog I receive a security permissions error;
'
Application attempted to perform an operation not allowed by the security policy. To grant this application the required permission, contact your system administrator, or use the Microsoft .NET Framework Configuration Tool.
If you click Continue, the application will ignore this error and attempt to continue.
System.Security.Permissions.SecurityPermission'
Followed by a Just-In-Time debug\Exception list of which of note '
The Zone of the assembly that failed was: MyComputer' is identified.
Checking the code it is specifically this line '
IManDMS dms = new ManDMSClass();' that is causing the error to be thrown.
I've attempted to change the security settings via the '
Microsoft .NET Framework 1.1 Configuration' – But this doesn't seem to have made any difference.
Would anyone be able to help identify what I'm doing wrong here & suggest a way to resolve this?
