Question

Hello All I am developing web application with help of solid Edge Dlls. My Web application is working fine in my local system  i hosted this web application into IIS. But whenever trying to connect a running instance of Solid Edge from the other system then it is giving below Error. Operation unavailable (Exception from HRESULT: 0x800401E3 (MK_E_UNAVAILABLE)) application = (SolidEdgeFramework.Application) Marshal.GetActiveObject(SolidEdge.Application); Note: This is Web application not Window or Desktop Application. Please suggest me.

I think Inorder to create an instance you are using Marshal.GetActiveObject(YourapplicationName.Application) which will work fine in your local system but not when you publish.This at time may not create instance in ROT. Instead of Marshal.GetActiveObject(YourapplicationName.Application you can use the following code: YourapplicationName.Application myApp = null; Type acType = Type.GetTypeFromProgID(YourapplicationName.Application); myApp = (YourapplicationName.Application)Activator.CreateInstance(acType true); ---------------------------------------------------------------------------------------------------------- Santhosh Kumar Innospire Systems
