Compatibility of NI IMAQ with measurement studio

I would like to know where the NI IMAQ driver software is compatible with measurement studio.

Hello,
NI-IMAQ driver and its API is fully compatible with Measurement Studio. If you have already installed NI-IMAQ with Measurement Studio support, see the following directory (default path) for shipping examples
C:\Program Files\National Instruments\MeasurementStudio\CVI\samples\IMAQ
Let me know if you have further questions on this.

Howdy Biswajit,
The IMAQ and Vision ActiveX controls you are using with Visual Basic 6 do not install with Measurement Studio. They are installed when you install the IMAQ software and include support for Visual Studio 6. Upgrading to Measurement Studio 8.0.1 will have no effect on your IMAQ controls since they are not related to one another. Purchasing Measurement Studio Professional or Enterprise packages allows you Visual Studio 6 support for other ActiveX components. Refer to this link for a list of ActiveX components included in those packages.
If you are asking about using the ActiveX controls in .NET, then take a look at this KnowledgeBase entitled Do NI-IMAQ and NI Vision Support Microsoft Visual Studio .NET?
Hope this clarifies things!

Connect CFP-2000 with Measurement Studio

Hi, I haven't understood how to connect a CFT-2000 module with Measurement Studio and VC++.
Can any one help me to find documentation and sample related this task?
I'm interested into this topics:
- is it possible to manage a CFT-2000 ethernet device with MAX? In ordere to use that device can i use DAQmx?
- which kind of data I will recive over ethernet raw, scaled..
- is it possible to select one particular board of AI?
- is it possible to execute multiple applictions (LabView and Measeurement Studio) connected with the same CFTP-2000 controller into one PC?
Thanks

Dear Bobby60,
First of all I suggest you this FAQ.
You can connect and configure cFP 2000 from MAX through NI-Field Point and Labview Real Time.
You have to use Labview Real Time to program an application on the cFP 2000.
Comms to Labview and Measurement Studio can be realized through OPC Shared Variable and TCP/IP. In the last option you will have to program your own server in labview RT and deal with multiple client stuff.

Program DAQCard-AI-16XE-50 with Measurement studio

Does DAQCard-AI-16XE-50 can works with a application created by Measurement studio? I have developed a data acquisition software base on PCI-MIO-16E-4, but I want swith the card to DAQCard-AI-16XE-50, it likes doesn't work, I don't known why?

Thanks lots to Chris and RamziH,
I have tested DAQCard-AI-16XE-50 on Max, it works fine all analog channels, the device nubmer is 1. So, in my program I am using this device number, checking the sample rate no more than 20kHz and no analog output function in my program, but it still doesn't works. Does CWAI works with DAQCard-AI-16XE-50? The DAQ driver version is 6.9.2.
Thanks again.

DataSocket SelectURL method fails with Measurement Studio and vista

The application uses the datasocket .SelectURL method to browse compact fieldpoint OPC items but the following error is raised:
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
   at NationalInstruments.Net.Internal.Win32.IAxDataSocket.SelectURL(Object startUrl, Object title, Object options, Object filters)
   at NationalInstruments.Net.DataSocket.SelectUrl(String startUrl, String title, SelectOptions options, String filter)
   at NationalInstruments.Net.DataSocket.SelectUrl()
   at DrillSense.Sensors.Sensor.SelectURL() in C:\DrillSense VS2005\DrillSense\cls_Sensor.vb:line 309
This method works with Windows XP Pro however.
The Development Environment includes:
MS Visual Studio 2008 with SP1
Measurement Studio 8.5.0 for VS 2008
Windows Vista Business
Is there a workaround to browse OPC items?
Thanks,
Barrett

Hi Barrett,
I would like to verify that the PC with Vista installed can see the OPC item. Do you have an alternative programming language which you can use to verify communication? If not, you may try Measurement & Automation Explorer (MAX). If you do not see the fieldpoint in MAX, I would try the suggestions outlined in this KnowledgeBase article.
How to Network FieldPoint to a Host Computer with Ethernet
It would also be helpful if you could provide a bit more information about your setup. I'm particularly interested in what .NET language you are using within Visual Studio (C#, VB.NET, C++, etc.). I may have to try and reproduce the behavior on my end, so if you could provide as much detail as possible it would be helpful.  Thanks Barrett!

Converting a Labview time into a string with Measurement Studio C++

In my Measurement Studio-based C++ application, I'll be sent a Labview
time in the format of a double, which I believe is seconds since 1904.
Does Measurement Studio for Visual C++ contain a function that will
convert that time value into a string format? I'd like to end up with
something like "hh:mm:ss:msec". I'm basically looking for the
equivalent of the Labview vi, "Format Time/Date String". If Measurement
Studio doesn't provide this, is there some other (hopefully simple) way
to do this?
I can request that the Labview application send me time in a string
format as well as a double; this will require several changes to the
Labview application sending the timestamp, but if that is a simpler
solution that's the option we'll take.
Thanks in advance,
Adam

Measurement Studio does not have a function for this, but you can do
this yourself by first converting from LV epoch (1/1/1904) to Unix
epoch(1/1/1970) and then using c runtime time functions
UNIXEpochOffset is the difference between the 2 epochs at GMT. To
convert to a UNIX system clock value, just subtract the sum of this
number and your time zone offset in seconds
lvTime is the value returned by LV timestamp
#define UNIXEpochOffset 2082844800
int _tmain(int argc, _TCHAR* argv[])
    __int64 lvTime = 3214396284; //10:48:13.173 AM 11/9/2005
    //GMT offset for Central Time is -6 (3600 seconds). You will need to account for daylight savings time.
    int offset = -3600;
    time_t unixTime = lvTime - UNIXEpochOffset - offset;
    struct tm *newtime = localtime(&unixTime);
    printf(asctime( newtime )); //prints out the time in a string format.
    return 0;

Frequency sweep with vb6 and measurement studio

hello! i hope you can help me with my problem
im using:
-PCI-MIO-16E-4 Daq-Card (at the moment, later i will get the PCI-6115 Daq-Card)
-Visual Basic 6.0 with Measurement Studio
my Problem: i want to stimulate a mechanical system with sine-waveforms of differernt frequencies, because i want to measure the resonance frequency of the mechanical system. For that i want the Daq-Card to output a sine waveform, the frequency should be swept from one frequency to an other frequency (i think the real values dont matter at the moment). The Problem is that the sine-waveform must not be interrupted when you change the frequency, because this would disturb the movement of the mechanical system.
I allready tried (without Measurement Studio) to use the fifo buffer (regeneration of thewaveform in the fifo) to be independent of the delays caused by the pc-system, but when i change the updaterate (change of the frequency) of the DAC there is again a dependence on the pc-system and the waveform goes to zero Volts for a while.
And i also tried to use the Chirp-Function (CWDSP.Chirp) of the measurement Studio, but with this function i have the problem, that i cant define how long the DAQ-Card outputs the actual frequency.
greetings A.Herman

Hello SG_ENGINEER,
So that is possible, but it is a completely different approach than that mentioned above. You would have to use a continuous analog output program and change the output waveform. Check out the attached example. I modified a shipping example to do an analog output and increment the frequency of the output waveform.

Problems with cwStats (MS 6) after evaluating Measurement Studio 7

I have the Full version of Measurement Studio 6 installed on my development machine. I recently installed Measurement Studio 7 to begin migrating our application to .NET. While recently doing some upgrade work on our VB6 project I started receiving an error when using the "full" capabilities of the cwStats control. It basically tells me that I do not have a license for the "full" version. I have installed the latest updates for MS6 but am still having the problem. Is this a known issue and is there a workaround?

Hello,
With Measurement Studio 7.0 we shipped a utility called ActiveX License Fixer. This was due to this known issue that the license of a released 6.0 will go into evaluation mode for 30 days if someone installs 7.0 released over the controls.
You should run this utility from the Measurement Studio 7.0 CD (it has a readme) and it will fix everything up for you.

Measurement Studio NumericEdit Control is Not Working

I installed Measurement Studio 2013 with Visual Studio 2012 Professional yesterday and imported my previously developed projects on (VS 2010 Express). Web controls and C# coding working fine.
I started Measurement studio chapter 2 first exercise to add control WaveformGraph, Gauge and Legend on my page and working but when add NemericEdit control then it gives me JavaScript critical error …….. SCRIPT1014 Invalid character. I am using window 7 and IE11 cleared cache already.
Please help.
Best regards
Bashir.

NumericEdit_ScreenShots.docx ‏298 KB

Hi Bashir,
I was able to reproduce this issue in IE11. Please note, Measurement Studio 2013 supports IE6 - IE10, so we have not tested the Measurement Studio 2013 ASP.NET controls with IE11. However, what you are seeing appears to be a result of IE11 dropping support for conditional compilation for javascript (https://msdn.microsoft.com/en-us/library/ie/121hztk3(v=vs.94).aspx). Because of this, when the Visual Studio debugger is attached to your ASP.NET website, you see an unexpected character exception.
Please note that the documentation for Web Browser Compatibility with Measurement Studio Web Forms Controls says that IE9 and 10 are only fully supported in compatibility mode. I took the liberty of testing IE11 in compatibility mode, and the Visual Studio debugger message stopped appearing.
Let me know if you have any questions.

How to use a Measurement Studio class in MFC

I am new to MFC coming over from VB.NET.
I have created a VISA class to measure something from an instrument and have a simple dialog box with a Button to invoke the measurement and display it to a text box. I changed the ID of the control and made a member variable for the text box and can code the OnButtonClick event to display text in the Text box as a test.
The problem is I cannot seem to create an object of the Visa Class that I built in the OnBnClickedRun()function. I can code the OnInitDialog() to make this measurement:
double power;
CGetBandPower BPower;
BPower.Run(power);
but want to do it when I click on the button. I am using VS.NET 2003 with Measurement Studio 7.0.

Any example for a MFC, WTL or Win32 without Measurement Studio?

It seems that NI wants you buy their Measurement Studio which can easily cost you a fortune. I am looking around a simple example for MFC, WTL without touching the measurement studio. But if you do not have measurement studio, NI only gives you very old examples in ANSI C which is difficult to implement to MFC or WTL. Apparently they want to increase their revenue by forcing you to buy the Measurement Studio. But I will not buy their hardware in the future if this is their strategy.
Anyone successfully implement the ANSI C example to MFC or WTL without measurement studio? Can you share an example?

Junqi,
Im a little confused with this request in general. What development environment are you using? Visual Studio? Also, what language are you coding in? We provide C, C#, VB.net, and legacy VB6 examples with our DAQmx driver that do not require measurement studio. They can be found in documents\National Instruments\NI-DAQ\Examples
Now forgive me if Im misinformed about this, but MFC and WTL are just libraries that have some of the windows API wrapped into them, correct? If so, I dont see how interfacing with them is any different than interfacing with any other library, or why this would cause issues with doing DAQ calls. If you need help with the MFC or WTL library, there are many good places to find help with on the internet. MSDN, codeproject.com, and many others come up as having examples of using MFC in various projects.
The MS examples dont install withough MS because they wouldnt be able to be used because they use libraries that are installed with measurement studio, so they would be nonfunctional and largely useless.

Coding error using measurement studio

hello..
can somebody tell me where can i get help on coding the measurement studio using VB.i'm doing an interface programing with a dc servo motor.i'm using a fuzzy logic controller(FLC) to make the output of the servomotor to follow the input, which i'm using a square wave input.i'm having coding problems on linking the FLC with the harware.i'm not quite good in visual basic, so can anybody help me with the coding?i can send the vb coding of the FLC and the hardware interface coding. i've successfully implement PID controller.. but i can't seem to make the FLC work. i think there's something wrong with the coding.
and how can i make the graph go more faster? output from the graph is very slow, compared if i probe the output from the servomotor harware using a digital oscilloscope.

Hi,
I recommend the Measurement Studio Reference as a resource. This reference is installed with Measurement Studio and can be found on your computer from Start>>Programs>>National Instruments>>Measurement Studio>>Help. The Measurement Studio Reference includes information on the Measurement Studio ActiveX controls and tutorials.
Next, is the FLC you are using part of a Measurement Studio Add On? Are you using the PID Toolset for VB?
Then, if the graph you are using is a CWGraph, you can access the properties of the graph by right-clicking and selecting Properties…. Click on the Graph Tab of the Property Pages window and check that Control Refresh is set to Immediate. This has the graph redrawn as soon as new data is available.

Error when trying to Install Measurement Studio 7.0

I did not mention this before, but the disks, Measurement Studio Professional Edition for Windows XP, Visual Studio.net and the Device Driver Reference CD installed fine. The Measurement Studio Professional Support for VIsual Studio 6.0 did not install properly. Do I even need to install this disk if I am running Visual Studio.net?

Hello EE
If you are using Visual Studio .NET 2003 with Measurement Studio, you do not need to install the support for Visual Studio 6 CD. You would only need to install this CD if you are planning to use VB 6.0 and VC++ 6.0
Hope this helps

Using graphs in measurement studio

I have written in multiple languages, and this �easy� �user friendly� software package has left me completely stumped. How on earth do you put data in to a graph and display it????? Can someone please show me code examples of firstly how to shove an entire array of numbers into a graph in VB.net using the new Measurement Studio and secondly how I could update a graph plot with a next acquired sample. Please help

"Where would I find "Creating Measurement Studio Strip Charts, Scope Charts, and Graphs" document. if it is on the website it is extremeley well hidden even from its own search engine. Does this specifically talk about VB .NET and measurement studio"
You can find this topic, as well as several other conceptual topics about the Measurement Studio .NET features with VB.NET/C#, in the Measurement Studio help that installs with Measurement Studio. You can find this help in two ways:
Integrated into VS.ET 2003/MSDN Help - Go to the table of contents, then the "NI Measurement Studio Help" node.
Measurement Studio standalone help - Go to the Start Menu, then Programs->National Instruments->Measurement Studio 7.1 for VS.NET 2003->Measurement Studio Documentation
Once you're in the table of contents, you can find the topic above by navigating to:
- NI Measurement Studio Help
- NI Measurement Studio .NET Class Library
- Using the Measurement Studio .NET Class Libraries
- Using the Measurement Studio Windows Forms .NET Controls
- Using the Measurement Studio Graph .NET Controls
The topic above is the second link in the list. If you have Measurement Studio 7.1 installed, this link will take you directly there.
"Using Measurement Studio ActiveX controls I wouldn't even know where to start, there is no AxCWGraph on any toolbar."
AxCWGraph is the name of the interop wrapper that is automatically generated by VS.NET when you add CWGraph to your project, so you won't see it in the toolbox. WaveformGraph/ScatterGraph is what you should use in .NET applications if you have Measurement Studio 7.0 or higher. I only mentioned CWGraph because this was posted to the Measurement Studio for Visual Basic forum instead of the Measurement Studio for Visual Studio .NET forum, so it wasn't clear if you were using the Measurement Studio .NET controls or the Measurement Studio ActiveX controls.
"If NI could just stick an example of exactly how to use VB.NET with measurement studio on displaying data and the various options available and stick it for all to see on the measurement studio home page it would be great."
There are several examples that are installed with Measurement Studio 7.1. If you installed Measurement Studio to the default location, you can find this examples at:
Program Files
National Instruments
MeasurementStudioVS2003
DotNET
Examples
UI
Graph
"I write in over ten different languages and scripts and fluent in two of them. It worries me that I can't even find the front door let alone open it."
I can understand how this could difficult if you were not aware of the Measurement Studio help and examples. Is it easier now that you know about this content that installed with Measurement Studio? If not, what else do you feel is missing?

Exe file will not start using a Measurement studio 2013 component

Hello,
I use Meausrement studio 2013 with visual studio 2012 and vbnet on windows 7.
On a new project (windows form application), i use a form and a ScatterGraph component. I compile, no errors and it works fine.
Now, i try to start this application on a another Windows 7 station. (The framework 4.5 is installed on its station).
The exe file is in a directory with the natrional Instruments dll files.
The exe file will not start, no errors.
PS: Before, with Meausrement studio 2010 and visual studio 2010 all worked fine.

Hi, virgule
It sounds like you are using the "Publish" feature in Visual Studio (a.k.a., ClickOnce) for deployment, is that correct? If so, unfortunately ClickOnce is not supported by Measurement Studio components.
If you are looking for a good way to deploy Measurement Studio applications, I would highly recommend upgrading to Measurement Studio 2015, which ships with Measurement Studio Installer Builder. You can read more about this here: http://www.ni.com/white-paper/52669/en/
If you cannot update to Measurement Studio 2015 and are using Visual Studio 2013, NI recommends using WiX for creating your installer. More information on WiX deployment can be found here: http://digital.ni.com/public.nsf/allkb/764B727C9BD2C4C686257C970053D059
