Ejecutable cvi 8.0.1

Tengo un problema al crear el ejecutable en CVI 8.0.1 . En la ayuda sale un mensaje de que si algun archivo aparece en rojo es porque ha sido movido o borrado, en mi caso es el propio ejecutable el que me aparece n rojo. adjunto un pantallazo para mostrar el problema. a ver si me pueden echar una mano. gracias

What are you unable to find? The distribution you built, or the application executable? Is this on the target system or the development system that you are referring to?
The distribution will be found in <project directory>/cvidistkit.<application name>/Volume.
The application itself is found at the location specified by Build >> Target Settings >> Application file.

Breakpoint en labwindows/CVI 7.1

Buenos dias,
El tema es el siguiente:
A veces cuando establezco un breakpoint en una línea de código de mi aplicación y selecciono depurar el proyecto (Debug Project), sale un mensaje avisandome de que la línea en cuestión no tiene código. Este mensaje ofrece varias opciones (continuar, cancelar, mover el breakpoint). Si selecciono la opción "mover", posiciona el breakpoint en una línea distinta que a veces es incluso una línea de comentarios.
¿Alguna razón para que haga esto?
Saludos....

Hola Killo,
Breakpoints son válidos cuando se encuentran en una línea ejecutable. Las líneas consideradas ejecutables son casi todas excluyendo declaraciones de variables que no sean inicializadas al igual que comentarios.
Por coincidencia sólo uno de los proyectos que probé en CVI me dió el mismo problema que mencionas. Creo que esto ocurre por algún problema en el projecto. Logré solucionar el problema al copiar el proyecto a otra carpeta. Otra solución es crear otro proyecto en el que incluyas los mismos archivos .c, .ui, .h que utilizabas anteriormente.
Espero que esto te ayude a solucionar el problema,

Cannot display square root symbol in cvi

I don't understand why this would be an issue, but if I'm writing in the source window (with the default font of NIEditor), I cannot display a square root symbol "√" - every time I type alt+251, I get "v". Ok, not a huge deal in the source window, but it is a big deal if THAT is what's being stored in a string variable I'm writing out to a file. Additionally, if I use the following to format a string:
"Fmt(setpointUOM, "%s<W%cT/P3", 251);", then setpointUOM = "WüT/P3". If I display this variable in a string control, it displays as "W√T/P3", which is correct, but if I use it in a Text Box or save it to a sql database, it displays "WüT/P3" which is unacceptable.
I've tried changing the fonts but nothing works or I get even stranger results. I've been dealing with/ignoring this since CVI7 and I'm currently at CVI10. Thanks for any help.
Solved!
Go to Solution.

The difference in the display between W√T/P3 and WüT/P3 has to do with the character set that you select for the UI control. From what I can tell, only the OEM code pages map the √ symbol to character 251, so if you want to see √ for that character, you should pick the OEM character set, in that control.
Entering √ with the keyboard in a CVI window seems like a much more problematic task. When you type Alt+251 on a CVI window, the keyboard driver is converting the 251 to 118 (the letter v). I don't know why it does that, but I noticed that the code that it converts 251 to varies, depending on your input language (which you can change in Control Panel>>Region and Language>>Change keyboards or other input methods). When english is selected in the language bar, it converts it to 118. With other languages, it converts it to other codes. I tried entering the unicode value for √ directly, which is Alt+221A (to enter unicode characters using the keypad, you have to follow the steps described here). But it didn't work. It still converted it to 118. I suspect the keyboard driver is doing this because it tries to map 221A to some symbol that is valid in the code page that corresponds to the input language, isn't able to, and picks what it thinks is the closest match.
In lots of other applications (but not all) you can type Alt+251 or Alt+221A and it works just fine. This is because those applications accept unicode characters directly. Unfortunately, CVI isn't one of them. It uses code pages (a.k.a. character sets, or multibyte sequences) instead of unicode, and symbols don't have a universal meaning; they depend on the code page.
Even if all this were not an impediment, you'd still run into the problem that in CVI 2010 you cannot change the font of the CVI source window to use an OEM character set. So, you'd still see it displayed as a v or a ü. In CVI 2012 you can change the change it, and so if you were using CVI 2012 you could conceivably use the clipboard to paste the √, but there is a bug in CVI that is preventing OEM characters from being pasted correctly (I realize the description says that it affects tree tooltips, but it's also generally affecting clipboard operations of some less commonly used character sets).
So, to make a long story short, I think you should continue entering the code directly with the Fmt function, at least until this bug is fixed. And make sure that all UI controls that need to display this string are using the OEM character set.

Using Excel with Visual C++ 6.0 (need a graph control that behaves as much like the one in CVI as possible)

I hate to beat this to death but I was unable to find a
clear answer to this question. Does NI provide Excel control from within
Visual C++ 6.0?
I read that NI supports the ANSI-C library only for Visual C++ 6.0 users:
Thread : "Re: Benifits of using measurment
studio for VC++ 6.0?"
NI REP : drohacek
Quote : "we made the decision to support Visual
C++ 6.0 users only through the ANSI-C interface and not through the Measurement
Studio MFC-based class libraries."
If there is a suggested way of controlling Excel from within Measurement Studio
for Visual C++ 6.0 then I’d love to know it.
If not, can a plain statement be made basically stating that if you want
to control Excel you can’t use a Visual C++ 6.0 environment even with Measurement
Studio support?
With .NET of course you can just decide to have Excel support added during
project creation. CVI can act as an ActiveX server and easily control
Excel just by building off the examples shipped with CVI. I see that
there is support, using the Measurement Studio for Visual C++ 6.0 Project Wizard,
for taking existing CVI projects and converting them to Visual C++ 6.0 projects
or for calling CVI libraries from a .dll from within Visual C++ 6.0. I suppose I could do the work
in CVI and then convert the project but I'm so deeply tied into all my MFC calls that I don't see
how I can cleanly include the CVI libraries into my existing VC++ 6.0 projects.
What I'm really after here is a visual graph control like the one in CVI that I
can use from Visual C++ 6.0. I purchased a 3rd party graph control for use
in VC++ 6.0 that works well but isn't really visual. I mean you can't
enter any values in it until you run the program and fill it out programmatically.
Then you can see which columns are two narrow, quit the program, adjust the
column width of your now empty control, and repeat, until you get the thing
looking the way you want. If I could call into Excel from within Visual
C++ 6.0 the way I do from within .NET
then I could use Excel to hold the table and just read in the values into my table
control at run time. Basically I'd use Excel as a visual development tool
for all my tables.
I do all my coding from within CVI and Measurement Studio for Visual C++
6.0. I'd use CVI for everything if I didn't depend so heavily on certain
outside controlled C++ .dll's. Could you please suggest then what I can
do to get Excel support for Visual C++ 6.0?
Last question :
Is there any plan to ever have a NI table control like the CVI table control for
use in Visual Studio? One that you can
completely set up before you do any compiling?
I imagine that the way Microsoft sets up their environment makes this idea impossible. Otherwise someone would
have come up with a truly “visual” table control before now.
Thanks,

Hello Grant
You can most certainly use Excel with VC++ 6.0. Measurement Studio won't provided you with any classes to talk to Excel in VC++ 6.0. This is because Excel allows control via Automation and you can use its automation API to do anything you need with Excel. This is what CVI uses as well.
You can see this MSDN article on how to set this up. This mentions VC.NET, but it should work the same way.
Here is one that talks about VC 6.0 and Excel.
Here is a code project article about this.
Even with .NET, you have to do thru the Excel Automation support. Excel started shipping with Primary Interop Assemblies (PIA) which are .NET wrappers about the Excel Automation object model. C++ Automation is definetely not as nice as .NET, BTW
See this document for more information about the Excel object model.
I would not recommend using the CVI Excel libraries if all you want to use them for is Excel automation. You will end up creating un-necessary dependencies and go through extra layers that way. You can make calls straight to Excel from VC++ without requiring CVI.
One quick observation about your excel approach. If you decide to use Excel as your table, you might be requiring everyone who uses your application to have Excel installed on their machines. Just wanted to make sure this was acceptable to you.
Have you looked at the Datagrid Activex control, which is one of the common controls that ships with Visual Studio? You can add it to Visual Studio by right-clicking and picking it from the list of installed activex control. If you have not already, you should check it out.
Microsoft has made significant improvements in the number of controls they provide with .NET. They have a Datagrid control that seems to be what you need.
Measurement Studio did add some high level classes for Excel and Word Automation that simplify some common tasks, but these exists for VS 2003 C++ and VS 2005 C++, not for VC 6.0. Underneath, we end up using the same Excel automation classes, so you can easily setup something similar for VC 6.0. Plus you can find alot of references online on how to use the Excel Automation object model with C++.
We currently have no plans in Measurement Studio to create a table control unfortunately. I am assuming when you said graph, you actually meant table, since Measurement Studio already provides a ActiveX graph controls for VC++ 6.0 that is very similar to the CVI graph.
On a side note, VC++ 6.0 is really really old. Have you considered upgrading?
To summarize
- Yes, you can use Excel with Vc++ 6.0 without mstudio.
- Try using the Datagrid Activex control if you just need a table.
- Measurement Studio provides high-level excel and word classes for VC++ 6.0
- Measurement Studio provides a graph control for VC++ 6.0 which is very similar to the CVI graph.
- Measuremnt Studio does not have a table control.
- VC++ 6.0 is really really old. Have you considered upgrading?

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:
You are correct, LabWindows/CVI integrates with the NI platform: NI hardware and software, like TestStand or LabVIEW (e.g. debugging source code from one software to another, seamlessly).
NI hardware and third-party hardware connectivity.
OpenMP support.
CVI integrates with intrument control.
CVI Run-Time benefits from User Protection.
Run-Time checking (e.g. for uninitialized variables).
Scientific User Interface Controls and GUI Editor.
Advanced debugging capabilities:
Remote debugging support from ADE.
Real-Time debugging support from ADE.
Memory leak detection using the LabWindows/CVI Resource Tracking Window.
Just-In-Time debugging.
Deployment: build custom installers and patches that you can ship as stand-alone easy-to-use installers.
LabWindows/CVI libraries: Advanced Analysis, Toolbox, Connectivity (Network Variables, Network Streams, DataSocket), etc.
Support for LabWindows/CVI Toolkits: SQL Toolkit, Vision, PID, RT.

How can I create an application in MSVC 6.0 to access my FieldPoint modules with CVI 5.0 libraries?

I have an application in CVI 5.0 that works. I am trying to export that so I can develop in MSVC. I need none of the UI provided in CVI, all I need are the simple FieldPoint commands provided in FieldPoint.obj. I have been stumped on this for weeks. I would write my own OPC client but the interface isn't even documented on what commands I would send if I did have an interface. I would prefer just to use the CVI libraries in MSVC 6.0. When I call the FP_Open function the program crashes with an RtlSizeHeap error.
Thanks,
Chad

In theory, creating a dll that encapsulates the FieldPoint functions should work in MSVC. However, National Instruments has not tested MSVC interface, nor have we publicized that this type of setup will work, therefore making support unavailable. The other reason for why we do not offer support of FieldPoint in MSVC is that we have not seen a demand for such an interface. Therefore, I recommend that you create an OPC Client that communicates with the FieldPoint OPC Server. One example of such an OPC Client in MSVC is to use Datasockets, found in ComponentWorks++. You can find this example at the following web site:
http://zone.ni.com/devzone/devzoneweb.nsf/opendoc?openagent&8FEAB5F73CFB68278625683A000B06ED&cat=7CDA3E51FEFC4AA2862568B80071A1E2
If you are using the
serial network module (FP-1000/1001), you can communicate with the FieldPoint modules using the Optomux protocol. For a complete listing of the Optomux commands refer to the FP-1000/1001 Programer Reference Manual located at the following web site:

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 can I convert a project from LabWindows/CVI 2010 to a Visual Studio 2011 project?

I have a good sized project, 12 source files, 14 headers, 1 uir, that I want to be able to edit and compile in MS Visual Studio 2011, MSVC++.
I remember being told that LabWindows dropped support for C++ in 2008 and no longer had a wizard for converting projects. I know I can go the DLL route, but I have never created a DLL before and wouldn't know where to begin with it. What would be the best way to go about this conversion?
Solved!
Go to Solution.

CVI 2010 still supports the Visual Studio Conversion Wizard for Visual Studio 2005/2008. We do plan to add support for VS 2010 in a future release.
If you need a VS 2010 project now, you can use the Visual Studio 2008 conversion wizard, then upgrade the VS 2008 project to VS 2010.

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!

Performance issues - CVI 2010

Hi all,
I have code I've compiled on a development machine - XP Pro with SP3 - and I'm seeing some performance issues on a similarly configured test machine. 2GB Ram, Pentium 4 CPU 2.8GHz. I had our IT person clean off another machine for me to use exclusively for testing (the other machine is our Tester's PC) and he gave me one with an Intel Core2 4300 @ 1.80 GHz. My code on my test machine runs like a top with NO problems.
We have another PC running Win7 on an Intel Core i5-2400 @ 3.10 GHz, RAM = 4GB. The code should be screaming on this machine but we're seeing performance problems here, too, that I believe may be due to the OS - Win7 may be a real hog.
Can anyone make sense of this? Is the dual core that much better even though that CPU is rated lower in PassMark Bench Ratings (http://www.cpubenchmark.net/cpu_list.php). We're trying to work all this out so we can advise the customer on which machine he needs to run our software.
Thanks,
Judy

Hi Judy,
Looking at the spreadsheet it seems unlikely that memory or cpu requirements are the root cause of the issue because the second machine in the spreadsheet with poor "performance" has almost twice the CPU clock speed and twice the physical memory of the fourth machine that runs well.
It sounds like your application is a fairly complex application that involves both GUI components and instrument I/O so what needs to be done is determine what part of the application is causing the bottleneck. There are many different factors which if not considered properly when developing applications that can cause performance problems such as thread deadlocks, device driver problems with the instruments or other hardware, needing to adjust the sleep policy for GUI events, writing to TDMS files in CVI versions before 2010 SP1, having memory leaks in the application code, etc. There is also a KB called Improving Performance of LabWindows™/CVI Applications that describes some changes which may help improve performance.
The overall message is that it is not only CPU speed and quantity of RAM available that can cause performance problems. A way to check the amount of RAM used by an application and CPU Utilization is to use the Windows 7 Resource Monitor to watch the application. This can be done by running Task Manager (ctrl + shift + esc), selecting the Performance tab and pressing Resource Monitor. This will open the Resource Monitor window where you can check CPU usage, Memory, Disk and Network usage for the application while it is running.
