I am trying to access a method in another VB6 application from my C# app. If
I add a reference to the relevant DLL it all works, and one bit where I need
to set a DB connection works by doing:
MyObj.setSolCon nection(ref ADOConn)
Because clients may have different versions of our app though, I need to
adjust to using late binding. Originally I was getting unknown name type
exceptions, but if I InvokeMember on SolConnection instead of
setDBConnection it cures that one... however I get a new problem. First, I
cannot pass the ADOConn with "ref", however on it's own I get an error
saying the number of parameters is incorrect. According the object browser,
the item is defined as:
void set_SolConnecti on(ref ADODB.Connectio n __p1)
Member of OPS._Case
Any ideas? Not sure what the __p1 bit on the end signifies, other methods
don't seem to have this.

Just to answer my own question...
I needed to use the "PutRefDispProp erty" bindingflags, and it seems to work
(at least in a quick test app I hacked up)

I can use dlopen/whatever to convert the function name into a pointer to that function, but actually calling it, with the right number of parameters, isn't easy.
