createobject

I seem to be having trouble getting my COM class library (.NET-based) to support early binding. I am creating a class library in VB.NET 2003 for use in Office 2003 VBA (and later for Office 2010). Documentation @ StackOverflow and elsewhere has brought me to this bit of code: Imports System.Runtime.InteropServices <InterfaceType(ComInterfaceType.InterfaceIsDual), _ ComVisible(True), _ Guid("<some valid GUID>")> _ Public Interface _TestCOMClass Function Test() As String End Interface <ClassInterface(ClassInterfaceType.None), _ ComVisible(True), _ Guid("<another valid GUID>"), _ ProgId(

Hey all this is my first time creating a COM object for a classic asp page. The process I followed when creating this COM DLL is this: 1) Used the Strong Name Tool (sn.exe) and placed the .snk file within the app. (sn -k myKey.snk) 2) Added: [assembly: AssemblyKeyFile(@"myKey.snk")] [assembly: ComVisible(true)] to the AssemblyInfo.cs.

In Visual Basic.net, can I create an Object, or a List of T with the type from another object.

VBA code works great: Sub testVBA() Dim wb As Object ' Lotus123.Document Set wb = GetObject("S:\Temp\T\0375D.WK3", "Lotus123.Workbook") End Sub VB.net code fails: Sub TestVBNet() Dim wb As Object ' Lotus123.Document wb = GetObject("S:\Temp\T\0375D.WK3", "Lotus123.Workbook") End Sub In VB.net I get a FileNotFoundException: "File name or class name not found during Automation operation." As I can run it from VBA that means the file exists and that the class name exists. So why doesn't it work and how can I fix it in VB.net. EDIT: I guess I'm not sure how to start diagnosing this: Obviously the
