Is it possible to convert LabView data into OLE variant?

Hi. I'm using Activex Data Objects (ADO) to communicate with MySQL. Some ActiveX methods give OLE variant output, with "Variant Type" like "VT_ARRAY|VT_UI1", "VT_UI1" or "VT_BSTR". With some deduction and trial and error is relatively simple to extract data from this OLE variants and convert them to LabView data types. The problem is when I try to input variant data to some ActiveX methods, it almost always give me errors, I suppose because it expects the same type of the outputs, this is: OLE variants. Now, the question is: ¿Is there any way to convert LabView data into OLE variant data? ¿How?
I've been searching and found a lot of posts about problems when passing variant data into ActiveX, saying that sometimes SAFEARRAYs are needed, sometimes saying that there were some bugs in LV6, giving some workarounds to this bug and saying that it is fixed in LV7.1, but the supposed workarounds don't work and the bug is still present in LV7.1, if it is really a bug.
I think that if I could put LV data into OLE variant shape I may find an answer and solution to this matter.
Thank you

Below I describe how to handle OLE Variants, but I wanted to mention that LabVIEW does have a Database Connectivity toolkit (http://sine.ni.com/nips/cds/view/p/lang/en/nid/6429) that has already created a set of VIs for ADO. You might check that out first.
However, handling OLE Variants in LabVIEW is automatic. LabVIEW itself has a variant datatype. When you use the ActiveX property or invoke nodes and one of the parameters is an OLE Variant, it is automatically converted to a LV Variant. You can then use the LV Variant VIs (such as "Variant to Data" and "To Variant").

Can some body help me to develop labview code for generating pulse to drive ac servo motor

can some body help me to develop labview code for generating pulse to drive ac servo motor... i am using NI 9401 card ....tnx

Driving an AC servo motor would (I missed AC on the previous msg) requires some complex hardware. This is generally done by drivers specifically designed for this purpose. I doubt you will be able to accomplish this with the hardware you currently have and it might be cheaper to just buy a driver for it and control the speed through the driver.

How to convert LabVIEW 2.2 for Mac to PC

Need to convert labview software from MAC to PC.
Moved files from mac to pc. No files with .vi extension. several resource.frk files in sub directories. Is there any instructions for conversion or is this not possible?

I've heard of people doing this before. It's been a couple of years but the process involved going from LV 2 to 3 on the MAC. Then from 3 MAC to 3 LV. Then use the LabVIEW converion kit. You may be able to bypass the 2 to 3 on MAC step.
From my understanding you can open LV 4 and onwards VIs with LV 6. Here's a Knowledgebase entry you might find useful:
http://digital.ni.com/public.nsf/websearch/6f80a168949d5799862569310076f14b?OpenDocument
Another KB entry discusses how to move files between the PC and MAC:

NI LabVIEW 2014 Digital Electronics FPGA Board Driver

Hello all,
When NI LabVIEW 2014 Digital Electronics FPGA Board Driver Release date?
Thanks.

Hi mlewis1973
We have no information regarding the next release of this driver yet. As you mention, the 2013 version is available, so, for now, the solution would be to use LabVIEW 2013 until R&D gives us an update regarding this topic.
Thanks!

You will need to replace the front-panel graph. Downconversion sometimes corrupts graphs.

Has Apple ever fixed the fan issue that results from upgrading the hard drives on 2009-2010 iMacs?

Has Apple ever fixed the fan issue that results from upgrading the hard drives on 2009-2010 iMacs?
My CPU fan defaults to 3000RPM. I can rev the fan higher with 3rd party Fan controllers, but no lower than 3K.

OR you can short out the original temp sensor, to make the fans rev at quieter speeds.
You can also install an optical temp sensor in place of the old one, it will still read temps and adjust the fans accordingly, just not as good as an internal sensor.
Use something like this:http://www.ebay.com/itm/New-922-9229-Cable-Temp-Sensor-Optical-iMac-27-inch-Late -2009-2010-/111106349896

Good Luck!

How can I use a labview VI as a CVI instrument driver

I have a VI for the Keithley 485 that would like to convert into a form usable by CVI. I don't have labview so I cannot generate a DLL based on the VI.

daquiry:
I've downloaded the 485 driver from both the NI Instrument Driver Network and the Keithley site, any they are both written natively in G (LabVIEW). The driver is rather simple, and is just making 488.2 / VISA calls. Keithley's site also doesn't offer drivers for the 485 in any language other than LabVIEW. This surprises me. I would suggest contacting Keithley and verifying that no C driver exists for the 485. If that's the case, then you may have to write a driver yourself. The 485 Quick Reference guide should have a description of all the available GPIB commands, along with sample code. Since you probably won't need the full range of functionality of the GPIB interface, writing a driver for what you do need shouldn't be t
oo bad.
I've written a short instrument driver which contains only a simple read() function. In implementing this, I've endeavored to translate the G code into C, but unfortunately, I don't have an instrument, so I haven't been able to test it.
Hope this helps..

R&S SMG driver

Hi,
I have downloaded R&S SMG LabView driver, but I failed to open it. I am using LabView 8.5, and the driver is for LabView 5. Is that why I can't open the driver's library? I appreciated your response.

It should be R&S SMHU driver. The driver link is below:

Does anyone know where I can download LabView driver for this instrument?

Convert labview 7 to 6

Hi folks,
I'm developing the automation for analyses and I neet to use a pump
connected via an RS-232. The pump manufacturer gives the driver
fit to LabVIEW 7.1E; unfortunately I have access to LabVIEW 6.1 only.
Would you mind converting the enclosed package to v6.1?
Many thanks in advance.

Need to convert labview files from version 4.0 to 8.6

I have a few labview .iv files that I need to convert to version 8.6. They were created in version 4.0. Can I download an intermediate verison of labview to process the conversion? Or can i order a cd?

Typically, you would need access to several version of LabVIEW to do the conversion.
Open the 4.0 VI in 5.1, save.
Open the 5.1 VI in 7.1, save.
Open the 7.1 VI in 8.6, save.
This example uses the most popular versions - ones you are most likely to encounter. 6.i was also popular, and might work somewhere in there.

How to convert Labview 9.0 vi files to 7.1 vi files?

Hi, I have a set of LabView 9.0 .vi files that I need to convert to 7.1 .vi files, but the current LabView 9.0 version only allows me to save it to 8.0 version. Thus, my questions are:
1) Can a user with LabView 7.1 open 8.0 files?
2) If not, is there any other way to convert 9.0 files straight to 7.1 files?
Many thanks!
Solved!
Go to Solution.

It requires two steps.
You need to open the VI's in LV 2009 and do a Save for Previous version back to LV 8.0
Then open that in LV 8.0 and do a Save for Previous back to LV 7.1.
If you don't have LV 8.0, then you can post the files to the downconvert thread and request there that they be converted to LV 7.1

How to output data when converting labview vi into matlab mex functions

Hi,
I am a fairly new user to labview and am currently working on labview
7.1. I have created a labview vi which can extract data from ni daq
6070e in real time. The problem is that this code has to be converted
so that it can be used with matlab.in order to do that i am using math
interactive tool kit which converts the labview code into mex files
which can then be used in matlab. Unfortunately i have not been able to
figure out how to output this data so that it can be processed in
matlab easily. i cannot afford any loss of information and all the
output must happen in real time. the o/p must take place after the fft
has been done. i am attaching the vi for convenience.There are 10
broken wires ,and this is the place where i want the o/p to be
generated.
Also do let me know if this vi can be further improved.
Regards

Manuj,
You seem to have misunderstood the way in which LabVIEW processes data. The code that you have produced will run in exactly the same way without the need for the case structure.
The code does not actually run the data from the previous case. It is merely processing data from the previous loop iteration, regardless of the case. If you were to remove the case structure, leaving only one copy of the code intact, and remove the toggle switch you have produced, or used the shift register which, I assure you would have worked, then you will have exactly the same functionality.
I have attached an example that uses the shift register to toggle cases, but also iterates that the case structure is not needed by using the same feedback node (and code) without a toggle switch or case structure.
Hope this helps you optimize your code

How to convert labview data into opc tag

Hi all,
Can any one please tell me how i can convert the labview data global into a OPC tag? I have some data globals reading and writing data to the globals. Now i wanted to use a PLC device to send its outputs to the field.
The PLC device will supports the OPC tags so i wanted t create OPC recognised tags in my labview. Is it possible. I saw that labview also having OPC functinalities. Please any one guide me in doing this.
I will be very thankful to them
Ramme..

As I said, I believe you can do this for globals as well by opening its front panel (double click the global) and using a DS connection for the control that represents that specific global.
As for other alternatives:
NI sells the DSC module which comes with an OPC server and with better tags.
You can use a common protocol like Modbus to interact with the PLC.
You can use the custom protocol used by the PLC.
The last two would require that you would change your program structure, so you would only want to use them under certain conditions.
I believe the practical limit for OPC tags with DS is a few hundred tags, but I never used it myself so I didn't run into it. You can try searching the forums to find out more.
Try to take over the world!
