Analysis Control CWDPS not supported?

[CWDSP]

I tried to use CWDSP.ReFFT in my application, but I got runtime error 30008. It said that I used a function required Measument Studio product for which I am not licenced.

I use Measurement Studio Professional for Visual Basic 6 that come with my Measurement Studio Professional Edition for Windows 2000/XP Ver 7.0 Package.

I don't think that to use CWDPS I have to order another sepecial Edittion.

Do you have any ideal?

Thank You,

Ben,

If you have Measurement Studio 6.0 Professional, you have access to all the base analysis library functions. Please see the product website ( http://sine.ni.com/apps/we/nioc.vp?cid=1413〈=US )for more information about which analysis functions are available for the Professional vs. Enterprise editions.

In your case, the CWDSP.ReFFT() function for 1D-real-array FFT analysis should be available to you in the Measurement Studio Professional edition according to the Product Data Sheet. It looks like you have a corrupt installation, so I would do the following:

1) Uninstall the National Instruments product(s) installed on your computer using the Windows control panel.

2) Double-check that there are no Measurement Studio ActiveX controls rema
ining on your computer at this point by looking in your Windows System32 folder for cwanalysis.ocx, and deleting it if it still exists.

3) Re-install Measurement Studio 6 Professional.

I hope this solves your problem.

Ben,

I tested the CWDSP.ReFFT() function with Measurement Studio 6 Professional edition in VB6, and came up with the same 30008 error that you received! I owe you an apology: according to the Measurement Studio 6 Product Data Sheet, you CANNOT use the CWDSP.ReFFT() function (part of the Signal Processing - Read and complex FFT analysis pkg) unless you have Measurement Studio 6 Enterprise Edition. I read the legend in the bottom corner of p93 wrong.

Again, I apologize for informing you incorrectly about this earlier.

David,

I understand you. I am not very satisfy with the way NI specifies what ActiveX controls and functions are available for Pro Edition. It seems like a secrete.

I wish if there would be the list that details what controls and functions are available for Pro Edition clearly. When I used the Evaluation Version, which I downloaded from the link to Pro Edition, I had no problem to use those controls and functions which until now I figure out that are not available on my real Pro Edition even it is appeared to be.

Well, I am not surprised that you got that confused.

Thanks anyway, David.
