Thanks for your help Paul, but I still haven't quite got it right...
My .odl file is as follows:
[uuid(86DB0EBB-848B-11D3-A474-00C04F34CF6A)]
library IDispatchTest
{
importlib("stdole32.tlb");
[dllname("IDispatchTest.dll")]
module test{
[entry( "test" )]
void test( [in] IDispatch* test_stand_context );
};
};
For completeness, here is my function definition too:
void __declspec( dllexport ) test( struct IDispatch *test_stand_context
)
{
AFX_MANAGE_STATE( AfxGetStaticModuleState() );
AfxMessageBox( "Testing 1..2..3.." );
}
When I build my DLL, and use it from Test Stand 1.0, using the function
test() returns an error message "The parameter information for this
function could not be read. It may contain an unsupported parameter
type." The IDispatch pointer seems to be causing this problem, since I
can change it to a long* in the .odl file, and the parameter
information is successfully read from Test Stand.
Any other hints are much appreciated...
Cheers,
Jeremy
