error inserting activex object

[BENIO]

Hi,

We've developped a dll in Visual C that registers an ActiveX server.  Now we want to integrate this activeX server in Labview 7.1.  We get the following error message:

"error inserting activex object : No such interface supported. we tried the following step as explaine in the link http://digital.ni.com/public.nsf/websearch/4F811A9B23F1D46E862566F700615B7A?OpenDocument but doesn't work.

Does anybody know how to solve this issue?

Thanks in advance for the help.

Are you using the ActiveX container control? As far as I know that only handles ActiveX controls and documents, not ActiveX servers. Just out of curiosity, does it work with a Visual C program?

Correct, you'll probably need to use the Automation Open in the ActiveX palette (block diagram) instead. The front panel container is only for ActiveX controls.

Hello Brian,

I am using a full development version of labview7.1 I cannot find the ActveX palette so cannot find the Automation Open as well, what version of labview should I use?is it possible to install drive for such application like ActiveX?

Look under All Functions->Communication->ActiveX in the block diagram palettes. I don't remember when ActiveX was added, but it was several versions ago so you're fine with 7.1. Also, take a look at examples\comm for examples with ActiveX, such as axevent.llb and actxpp.llb.
