How to get a return value from an ActiveX method

[Kirillenseer]

I have an ActiveX-control with the following interface

[code]

[   uuid(C1396B5A-D5E8-4B66-A353-BF66A13B1F58),   version(1.0)

] library ActiveX2Go {

  importlib("stdole2.tlb");

  interface IDisplaySomething;   coclass DisplaySomething;

[     uuid(3E8BB15D-2E76-4285-8950-90DE79CF6931),     helpstring("Interface für DisplaySomething Objekt"),     oleautomation   ]   interface IDisplaySomething: IUnknown   {     [id(0x00000065)]     unsigned int _stdcall DisplayMessage([in] unsigned int Input);   };

  [     uuid(37DB85BC-F974-4647-A6A4-1024873CB1A3),     helpstring("DisplaySomething")   ]   coclass DisplaySomething   {     [default] interface IDisplaySomething;   };

};

[/code]

According to what this looks like, the function DisplayMessage takes an unsigned integer and returns an unsigned integer. Yet the method call node in the attached VI (LV 8.6) refuses to emit any return value while recognizing the interface and method. Can anyone tell me what I'm doing wrong?

Thank you.

Hi,

this is kais from germany.

I saw your VI, I was not sure if you have selected any ActiveX Class. See my Screenshot.

Yes, I selected the class I created (ActiveX2Go seemed to be catchy enough to remember across languages).

[mkais]

you said: you've created a class. can you send me this class to reproduce the same Issue?

Did you use an NI Tool to create your Class? 

Can you describe your Problem with more Information? OS, Software Version, Tools used.

Best regards
