Hello All,
i am getting the following error when i use the EIF DLL (by creating the TLB
file and all the necessary steps needed) in a VB6.0 application
This is a sample testing that i am doing as my main task is to implement the
EIF in a COM+ application
Someone PLEASE HELP ME

The error message is pasted below

System.InvalidOperationException: Cannot raise events that contain field
types which do not have the 'InstrumentationType' attribute. Ensure that
System.String or one of its base classes has the InstrumentationType
attribute.
at Microsoft.EnterpriseInstrumentation.EventSource.RaiseEvent(Object
eventToRaise, RequestContext requestContext)

How are you creating the TLB file?
EIF is not directly callable from COM (except the
Microsoft.EI.Configuration.dll which is Com callable).
The M.EI.dll has a [ComVisible(false)] attribute to prevent regasm from
seeing it.

Now you could provide some sort of COM callable wrapper - so it thunks from
COM into your .NET wrapper and this calls into EIF.

The error below is indicating that the object you passed to
EventSource.Raise(<thisObject>) does not have the [InstrumentationType]
attribute on it (or one of its base classes). Event objects (see the schema
sample code and the other samples) are passed to the Raise() method.

Hope this helps.

Mike
