Downconvert VI Requests

[BSGMike]

Many thanks Gerd.

GerdW,

Thanks for the suggestion...

I wasn't really expecting someone from NI to expose their big secrets! 

I decided to exercise my brain and try to re-create the function of the "Application Directory.vi" in LV 8.6 since NI has hidden the block diagram and the help includes no details.  I haven't tested this extensively, but my "Application Directory 8.6.vi" seems to function as desired.  However, I haven't tried it in an EXE yet.

I hate it when a project requires me to work in older versions of LabVIEW; I get used to having the new features.

Dear All

Just wondering if a kind someone could convert the attached 8.6 VI (That's what labview told me when I tried to load it.) and convert it to 8.5.

Apologise for posting this request in wrong message.

Thanks very much.

Regards

Nigel

Every time I tried to downconvert it LabVIEW crashed. I always have this happen when trying to downconvert VIs that use a private .NET assembly, and the assembly is not available. Perhaps someone else may have luck. As a consolation prize I've uploaded the VI documentation which shows the code. You should be able to recreate the ring controls directly from the methods by right-clicking on the method's parameters and selected Create -> Control.

But....

The VI has numerous flaws:

• It was written without a main loop. This means the Run Continuously button in the toolbar is used. This is BAD.
• The VI uses the Abort function to stop, because it has no main loop. Also another BAD. 
• Errors get dropped along the way.
• The Connect button is a latching-type which means it needs to be placed inside the event handler for it so that LabVIEW can read the state of the button and thereby change it back to false. 
• There's a breakpoint on one of the methods.

I wouldn't use it without fixing it first.

Thanks for trying.

The programming code pictures will enable me to start recreating it.

I've got the DLL and library that goes with it.

Need to put Labview wrapper around them.

Once again thanks very much for all you've done.

Dear All,

I am looking to convert the drivers provided with the Keithley Model 3390 50MHz Arbitrary Waveform/Function Generator, from Labview 8.0 as they are provided to Labview 7.1

I have attached the Zip folder that is provided from the website.

Thank you very much for any help you can provide.

I get a !   Keithley 3390(2).zip: The archive is either in unknown format or damaged
