Hi,
I have created an assembley in vb.net by adding a class based on the
component tempate to my project. I have a public function called send
that has some parameters and returns a long type.


I have built the project and used regasm.exe to generate a type library

that is a COM Callable Wrapper.


My problem is that my public function is not visible as a method in the

COM interface. I have declared the public function as follows.


Public Function Send(ByVal MsgId As Long) As Long


Is this correct? if so is there anything else I have missed?


Thanks
Nigel
 
When you say "visible" by the meaning of Intellisense pop-up list while
coding, yes, Intellisense will not work with the COM interface of a .NET dll
by default. It is by design. However, there is a way to make it work. See

Click to expand...

In addition to what Norman wrote, you should avoid using Long in your
method signature since VB6 doesn't support 64-bit integers.
