ActiveX control "could not be loaded"

ActiveX control "could not be loaded"

G'Day everyone,

I'm having a problem with my activeX controls (SHDocVw.IWebBrowser2 for example) - when I load and run a LabVIEW 6i VI with an ActiveX container on the front panel, I get an error 97 (Unknown System Error in Untitled.vi) out of its method node. If I load the same VI into LabVIEW 6.1, I get the same error, and the container has "Control could not be loaded" written in it. This isn't just limited to the web browser control, but others too. (they used to work a week or so ago, and I can't think of anything I've done to the system since then...) If anyone has any ideas on how to fix this, I'd really appreciate it!

cheers,
Christopher

Re: ActiveX control "could not be loaded"

Try to register it. Run in MSDOS window regsvr32.exe name_of_ActiveX.ocx

Re: ActiveX control "could not be loaded"

Unfortunately, it was *all* of my ActiveX controls that wouldn't load. That said, A user of the Info-LabVIEW list came up with the answer: reinstall the RunTime engine - wierd....

thanks,
Christopher

Re: ActiveX control "could not be loaded"

Christopher,

Also, try repairing the LabVIEW 6.1 installation. Go to Add/Remove Programs, choose LabVIEW 6.1, and then choose Repair. This should fix this issue.

Re: ActiveX control "could not be loaded"

Thanks Randy - what I actually ended up doing (as suggested by a member of the Info-LabVIEW mailing list) was reinstalling the runtime engine: weird...

thanks,
Christopher

Re: ActiveX control "could not be loaded"

OK, this has me very confused! I am using both the common dialog and excel activex controls in vis. They all work fine on my development system (which has VB6 installed) but _none_ of them work on a different system I am using to debug....I get the same story of "error 97" when I try to invoke or set a property and the control on the front panel has "could not be loaded". I have tried regesitering the .ocx, which (appears) to work fine, and have "repaired" labview and reinstalled the RT engine. (labview 6.1)

Am I screwing up here?!
Thanks for your help.

Re: ActiveX control "could not be loaded"

I have had a similar problem recurring with the web browser activeX control. It is in an app. I have delivered to a customer and periodically this error occurs and they have to reinstall. This does not inspire confidence nor make them very happy.

Re: ActiveX control "could not be loaded"

What I meant to ask in the above post is has anyone found a solution? I can't keep telling them to reinstall every few weeks.

Is this likely to be fixed in LabVIEW 7?

BTW, How does one find out the filename (*.ocx) of an ActiveX control to register it?

Thanks,
Mike

Re: ActiveX control "could not be loaded"

In labview you can pull up a list of all active X controls by dropping an active X container on your front panel.

Right click inside the container and select insert Active X Object.

This will give you a list of Active X controls on your machine.

Also, you can look in The System32 directory on most machines and sort by type. All the active X controls will be in alphabetical order and have the extension .ocx.
