Visual Studio or LabWindows/CVI?

I have a bit of a dilemma.
I currently own Visual Studio 2010, IMAQ Vision Development Module 2013, and Measurement Studio (not sure of version). I currently do all of my programming in VB.net. Because IMAQ VDM is stuck in .Net framework 3.5 and there will be no further .net development by NI, I need to plan for the future. My applications need run on Win 8, 9, 43, or whatever my company decides to migrate to from Win 7.
My understanding is that the NI modules I currently own will work with LabWindows/CVI. Correct? I also believe I can use them with C++ using the VS IDE. Is this also correct?
Within my applications I do a lot of interfacing with Excel, writing text files, and interfacing to non-NI devices (cameras, DAQs, scanners, etc). I am able to do these things pretty easily using VB.net using vendor-provided SDK's.
Therefore, my question is this...given the investment I have in software already, do I gain anything by migrating to LabWindows/CVI? What do I lose?
I should point out that regardless of the path I choose I will need to bone up on my programming skills in the corresponding language.
Thanks for all your help!

Hello Steverino!
Here are some advantages when using LabWindows/CVI over Visual Studio, which make the product more suitable for various industry-related applications:

How do I send e-mail to a distribution list using LabWindows/CVI?

I need to be able to send e-mail to a user-defined distribution list using LabWindows/CVI? Has anyone done this? Any ideas where I could look?

I commented on something similar to this awhile back. My issue was that I had the base version and didn't have the Internet classes. So this external app worked like a charm
It has a lot of command-line inputer options to use as well.

How to use CAN256 and CAN257 in Labwindows CVI?

I am trying to learn about CAN programming in LabWindows CVI. None of the samples do anything other than generate cryptic error messages. I do not have a card or interface device yet, but reading in the help files I found this:
"NI-CAN provides a virtual CAN card with two interfaces, CAN256 and CAN257. The two virtual interfaces are connected by a virtual bus. When you write CAN frames to one virtual interface, those frames are received by the other virtual interface, and can be read as channels. This feature allows you to read and write CAN data in the same manner as two real CAN interfaces connected by a real CAN cable. The conversion does not require real NI CAN hardware, and your application is not required to check for specific CAN IDs."
I modified the Waveform ouput project and add CAN256 to the dropdown in the uir file. However when I run it, I get the same error message as always, error -1074388725.
Is there an example CVI code someplace to demonstrate the use of these virtual channels?

Thanks Drew.
Ultimately, my customer provided me with a WriteCAN256.vi and ReadCAN257.vi that were perfect for my needs. The WriteCAN256.vi along with my NI USB 8473s allowed me to provide data collection on multiple CAN devices and to verify that my Software can handle all data types from CAN devices.
Note: My customer allowed me to share his .vi's. They are enclosed ...

How to use the checksumdll.lib in LabWindow/CVI to create CRCChecksum();

Hi All,
Any one know how to use the checksumdll.lib in LabWindow/CVI to create CRCChecksum() ?
Thank you.

Do you ave some documentation about that dll?
Have you looked into dll properties searching for vendor name? Maybe you can look int vendorìs site and obtain some help.
Ultimately: are you forced to use that dll or can you use any software to calculate the checksum? There are several CRCs that you can use: provided you know which is the type used you could find an algorithm to calculate the CRC and check an existing one.

How to set a DMA transfer type for PXIe-6536 in LabWindows/CVI?

I have a PXI chassis PXIe-1078 with a controller PXIe-8115 running under Windows 7. The digital output board is PXIe-6536.
I use a function DAQmxSetChanAttribute to set a property DAQmx_DO_DataXferMech to a value DAQmx_Val_DMA, since I want to use a direct memory access data transfer. This wokred well with a PCI-6534 board using the same LabWindows/CVI code before migrating it to the PXIe system.
Unfortunately, running this code on the PXIe system reports a DAQmx error -200452: "Specified property is not supported by the device or is not applicable to the task".
The task is created in the following simple way (the board name in MAX is 'Dev1'):
   DAQmxCreateTask ("digTask", &digitalTask);
   DAQmxCreateDOChan (digitalTask, "Dev1/port0:3", "DIG_CHANNELS", DAQmx_Val_ChanForAllLines);
   DAQmxSetChanAttribute (digitalTask, "", DAQmx_DO_DataXferMech, DAQmx_Val_DMA, 15);
How can I solve this problem? How is it possible to choose between different transfer types?
Thank you in advance for any hint!

Hi CavityQED,
The PCI-6534 is a "Digital I/O" board while the PXIe-6536 is a "High Speed Digital I/O" board, that's why they don't have the same properties.
By the way you can use DMA transfer with this method :

How to get bar graph in word in labwindow/CVI ?

how to get bar graph in word in labwindow/CVI ?

ashwinic9,
spawning your question over more and more threads (the present one, this one and this other one) won't give you a faster answer; instead, it will irritate forum users!
Especially if you have at your disposal a fast way to perform a test. I pointed you some days ago to word report example, that writes a table to a word document: did you tried changing the graph into a bar graph and generating the report? I have done it for you and the result is OK, as you can see in the attached document.
Now, since the example works well, there must be something in your particular situation that prevents the graph to be shown; that is: you must add some more data on your actual problem and maybe a small example that exposes the problem.
But please: keep active only this discussion and let the other threads die!

I used to working with Labwindow CVI and i would like to know how can i use the commands "loadpanel" and "Displaypanel " in Labview. Using Invoke Nodes?

I want to make another panel appears and runs, but i don´t want to use a subpanel. So, i would like to use somenthing similar to Loadpanel and Displaypanel, that you can use in Labwindows CVI, but in Labview, is ti possible?I hope your answers, thank you!!!

Hi Bichillo,
I posted an example here.

How does the URL of DataSocket constitute?And how to use it in LabWindows/CVI ?

Hi ！
There's a problem puzzled me some days.How does the URL of DataSocket constitute ? And how to use it in LabWindow/CVI ?
For example.I have downloaded a code in http://zone.ni.com/devzone/cda/epd/p/id/3787.I want to make it work properly.So I configure my DataSocket Server Manger according to the URL of this statement.
DS_Open ("dstp://weather.natinst.com/weather/current",
DSConst_ReadAutoUpdate, DSCurrentCallback, NULL,
&dsCurrentHandle);
My DateSockket Server Manger is configured as:
However,it could not work properly when I debug it.
There's a introduction at the top of the code."You may need to replace the references to weather.natinst.com to 130.164.140.10 if the DNS isn't working properly."So,I modified the statement into
DS_Open ("dstp://130.164.140.10/weather/current",
DSConst_ReadAutoUpdate, DSCurrentCallback, NULL,
&dsCurrentHandle);
but,it did work properly.
We want to communicate with other computers via the URL of DataSocket in LabWindows/CVI.Whereas,how could we make it ia the URL ?
If anyone could help me solve this problem,I would appreciate it very much !
Best regards.

I wouldn't care success or failure,for I will only struggle ahead as long as I have been destined to the distance.

Hi !
Thank you very much for your reply! I will accept your advice.
Besides,I have another question.If I want to visit other computers or other websites，how does the URL of DataSocket I constitute ? Does the URL has any relation with the DataSocket Server Manger ？If does,how to configure the DataSocket Server Manager to let them connected.If they have no relation,how to use the DataSocket Server Manger ?
After all,I want to know how to use it in LabWinows/CVI ？
Thank you very much !
Best regards!

LabWindows/CVI 2013 SP2 stops working when I try to open a file using the project file menu.

I have windows 7 on my system and sometime late last year I starrted getting a Windows dialog telling me that LabWindows/CVI has stopped working when I try to open a file from the project file menu. I also get an error when I run a project debug mode and use a selectFilePopup in the code. The error says, "The program has suspended execution at address 0x75D5025E. No source line information is available." I've tried removing and reinstalling CVI to no avail. Any suggestions?

Constantin,
Thank you for your response. I've attached screnshots showing the version details for kernal32.dll and ntdll.dll. I also looked at the updates to see which might have been installed when the problem started. Unfortunately there are 15-20 updates every month. I didn't take note of when the error started to occur. At first it only affected my ability to open files from within the project (i.e. file->open->Source, etc). Then I went back to modify a project that had a SelectFilePopup and found that that wouldn't work either.

How to access the result list in teststand after execution using labwindows/cvi

I am developing a user interface in labwindows/cvi that runs multiple teststand sequence files and would like to combine their reports (generated in teststand) into a single file at the end of a UUT. What is the best way to do this? At the moment, I'm trying to access the result list local variable after the execution has ended using API calls from labwindows/cvi and an end-of-execution callback event but those run-time variables do not exist anymore. How do I get a hold of the result list array at the end of an execution? I would like to grab this variable and pass it along from sequence to sequence using labwindows/cvi and not teststand itself. Is this possible? Any help would be great.
Thanks in advance,
Luis

Hey Luis,

Yokogawa UT driver for LabWindows/CVI 6.0 won't translate to LabVIEW 8.6?

The device driver for the Yokogawa UT series furnace controllers is in LabWindows/CVI 6.0 and I would like to use it in LabVIEW. I tried to use the utility to convert from LabWindows/CVI to LabVIEW, but it said it couldn't and that the device driver is from before LabWindows/CVI 5.01.
In any case, here is the series of events.
I downloaded the LabWindows/CVI to LabVIEW Converter, from
the page on LabVIEW's developer's connection that had the driver for the
Yokogawa UT controller.
From an empty LabVIEW Block Diagram, I click
Tools>>Instrumentation>>Create LabVIEW Interface to LabWindows/CVI
Instrument Driver...
This takes a little while to load. During loading an
FC_Interface_Main.vi runs, apparently trying to find a file.
Once that is done, the two options are Basic and Advanced. I leave
basic selected. I click next. browse to find the ykut.fp file from the
driver I downloaded.
I then click next. The error window that is seen in the screen shot is
then shown.
I called a tech support guy at NI about this, and I e-mailed him with all the above, but there was no reply, though the conversion utility is no longer available on the same web page as this specific device driver.
In any case, if anybody could give a little guidance, it would be appreciated.

Hello Screamingzebras,
I converted the .fp file to be version 5.5 and ran the utility that was mentioned. I have attached two files to this post. "ykut.zip" is the converted .fp file (version 5.5). "yut.zip" is the converted instrument driver.

How to edit the list box items in labwindow/CVI?

how to edit the list box items in labwindow/CVI?

Listbox items cannot be edited directly in the control: what you can do is to select a line an, transfer its content to a textbox control, edit text there and move text back to the listbox control. Available interactions with the listbox control are listed in the help.
An alternative to it is to use a tree customized to appear like a listbox: tree item labels can be edited directly in the control, at least those in the base column of the tree. You can look at the example \samples\userint\treelist.cws that shows how a tree can be customized this way. I haven't opened it, but this old example too should show the ability to edit tree cells.
