InvokeDispMethod fails intermittently

[RichB]

Hello,

I've developed an object that late binds to COM objects using
Activator.CreateInstance and <Type>.InvokeMethod.

The object is held within a ASP.NET application which is used heavily, thus
requiring the late binding to be activated regularly. Unfortunately, on
more than once occasion RuntimeType.InvokeDispMethod has thrown an
unspecified error.

Has anybody encountered similar problems and can anybody offer any kind of
solution?

Thanks in advance,

Richard Bower.

Hi Richard,

Hello,

I've developed an object that late binds to COM objects using
Activator.CreateInstance and <Type>.InvokeMethod.

Could you please explain what kind of COM object your instantiating?
It could be that the problem really exists there, and not in the late
binding/calling.

Lars,

Pretty basic C++ COM object, no transaction or state, IDispatch interface
that is sat in a COM+ package.

Thanks

Richard.
