COM object in asp.net
I have an ActiveX OCX that I'd like to use on the server side, IIS, ASP.NET 2.x. It's a simple control, Just three properties and 4 methods. I've added the reference in VWD and it's created a wrapper called Interop.MyDLL.MyControl and placed a DLL called Interop.MyDLL.dll in the BIN folder on IIS. I then put a button and a textbox on my page... in the button's click event I added (using VB)...
Dim MyNewControl As New MyDLL.MyControl MyTextBox.Text = MyNewControl.MyProperty opening the page in the browser and clicking the button I get... System.Runtime.InteropServices.COMException (0x8000FFFF): Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED) at System.RuntimeType.ForwardCallToInokeMember(String memberName, BindingFlags flags, Object target, int32[] aWrapperTypes, MessageData& msgData) at MyDLL.MyControlClass.get_MyProperty()... Hum... fluoronator |

This problem has been resolved... sort of. A little Googling proved that using an OCX in .NET without a graphic container is impossible for ME and probably pretty difficult for someone of average intellengence! As a work-around (this will come in handy again someday) I created an ActiveX Dll in VB6, placed the OCX on an invisible form and exposed the methods/Properties. Instead of referenceing the OCX from ASP.NET, I referenced this DLL instead. I'm still trying to get over the fact that it WORKED!!!
