How do I access an ActiveX control's interface when have its generic control refnum in hand?

Perhaps this would be useful.

Perhaps, if I had LV 7.1. 😛 😄

I'm running 7.0

Hi All,So after a lot of time trying to verify how to do this I have been able to find out for sure that I is not going to be possible.  There is no way to look into the class using the reflector in LabVIEW.  Sorry to be the one to bring the bad news.

How do you get that icon with the funky arrow on its left that states ActiveXControl?

As you've found out, when you get the reference via the Controls[] property all you get is a generic reference. Even if you cast it to be an ActiveXContainer all you get is a generic ActiveXContainer. You can cast it to a specific ActiveX control by wiring a (direct) reference to an ActiveX control, but you have no way of knowing if the cast is correct since the casting is likely to give no error.

I don't know if it's possible to do what you want with ActiveX controls. Perhaps Adam may be able to dig something up.

I'm not sure which icon you're referring to, but if it's the one labeled "WindowsMediaPlayer", that's just a reference to the ActiveX container. I'm using 8.2, so the icons may be a little different.

Can't use a reference like that in 7.0.  That was the first thing I tried. 😞

Oh well.

[paul_a_cardinale]

Here it is in 7.0

Hmm, well that means that my ActiveX control has no name then. 😉 Just looking at the data on the png I uploaded shows that the last digit is 0.  Interesting way of determinging the string though. 🙂

Thanks

I once thought I saw an icon that showed that funny arrow on LV7.0 and it was a reference to "this vi".  Was I imagining it?

Thanks
