How to handle cursor position when x axis is updateing
Hi, i have an applicatio that receives data and plot it in real time. I want to have a cursor that will show y value, but the problem that have is with the fixed x value for the cursor. My x axis is a timescale that is constantly moving, i have set a cursor but it disappears when data start coming in, because the x axis is incrementing. Is it posible make cursos relative to the x values? Or can i somehow bind it to the mouse cursor and to have it show me y value when i point my mouse cursor to a specific point on the graph?
Thanks

VS2019 C# NI-VISA driver issues
I am workling with the latest Visual Studio Pro 2019 and C#. I have gone oveer a lot of VISA and GPIB information and am working up a VISA/GPIB driver for NI and IVI compliance. They IVI one seems fairly straightforward, just hard to decipher some of the commands needed for advanced features. On the NI side the older NationalInstrumewnt.ViasNS is no longer valid or buildable. The newer NationalInstruments.Visa is considerably different and older code generate a lot of errors as so much has changed. Anyone have any background using the newest VISA .Net assembly and can advise some. Or IVI.VISA. Or if you have an example c# VISA driver that would be cool. The latest .Net NI page mentions the changes but they have not updated their example.
Thanks in advance.

Sell and Deploy Applications Using Measurement Studio Libraries
Hi,
I am currently evaluating Measurement Studio and have a question concerning licencing and application deployment.
If I own a Measurement Studio Professional licence and write an application on a PC on which Measurement Studio is installed, would I be allowed to sell and able to deploy this application to a user who has not bought a Measurement Studio licence?
And if yes, are there any obligations to include a licence notice in the application?
In case it's relevant: I only need the TDMS-Libraries for writing and reading TMDS files.

3D style LEDs don't show in published app (MS2019 + VS2019 + Win10LTSB2016)
I've downloaded the trial version of MS2019 and I've faced up with the issue that 3D Style LEDs don't show in the published application that is running on another computer.
What is the root cause of this issue? Is it a trial version issue (no actual license)? Some DLL is absent or not included in the published application?
The all working fine on local (developer's computer).
Thanks in advance!

Calculation and Display of over time period avareged values
Hello dear community,
I want to add to my data aquisition software in .NET the feature to calculate and display the avarege value for every x second. For that purpose i have implemented in my reading loop a loop that stores the data in an array, calculates the avarage every x seconds and transfers the data to an dataobject, that is beeing read in the Plotframe. Unfortunately i get Error -200279. I tried different thing, raising buffer size, reading more samples, but nothing worked.
I think it must be said that i have two channel groups. The aquisition begins by starting the Programm:
Private Sub butStartProgramm_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butStartProgramm.Click
Me.butStartProgramm.Enabled = False
Me.ButStartMessung.Enabled = True
Me.butEndeProgramm.Enabled = True
setFenster() ' here i call the Frameplots
objScan_Teil2.Start() 'here is beeing started the aquisition of the second channel group, executed throug a separate class
iniKanaele() ' here the channels of group 1 are beeing initialisated
'starting the aquisition of channel group 1

analogCallback, Nothing)
Catch exception As DaqException
MessageBox.Show(exception.Message)
taskRunning = False
Me.butStartProgramm.Enabled = True
Me.butStopMessung.Enabled = False
myTask.Dispose()
End Try
End If
End Sub
the async.callback looks as follows:
Private Sub AnalogInCallback(ByVal ar As IAsyncResult)
Dim Messdaten_Teil1 As Double(,) 'Aquisition array
Dim MittelwMessdaten_Teil1 As Double() 'Array for loop avareged values
Dim PeriodenmittelwertOsz As Double() 'Array for over time period avareged values

Point-by-Point Filter
Hello,
I would like to know how to do a point by point filter, in the Help the point-by-point filter is referred but it mentions LabView and I do not find how to implemented in C#.
I am using a NarrowbandFirLowpassFilter and NarrowbandFirHighpassFilter. FilterData accepts only arrays
publicdouble[] FilterData(double[] inputData )
If not possible with this filter, can you recommend me which filter to use?

Undo Problem
As we know that the WPF graphs use Shift+Right-click for Undo like the Windows Forms graphs in the Measurement Studio 2015 release. I use a TabControl to show different graphs. After Zooming,i change to other tabitem, and then i change back to first tabitem, I can not undo last operation.

Measurement Studio Runtime License
I am developing an application using VB.NET and Measurement Studio. I built the installer using the Measurement Studio Installer Builder, but when I run the application, I see the attached error.
I may have misunderstood the license. DO I need a separate license for each installation of the executable that I want to have? Or is it covered by my development license and I built it wrong?

Exercising a Simulated PXI-6529
Summary: Attempting to use C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DotNET4.5\Digital\Generate Values\WriteDigChan\CS or C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DotNET4.5\Digital\Generate Values\WriteDigPort\CS to access a simulated PXI-6529 results in error -200012 "Specified physical channel does not support digital output."
Steps to recreate:
- Open NI-MAX
- Right click on "Devices and Interfaces"
- Select "Create New..." from the context menu
- Select "Simulated NI-DAQmx Device or Modular Instrument" from the "Create New..." dialog
- Click the "Finish" button
- Type "6529" in the "Create Simulated NI-DAQmx Device" dialog and select the resulting "PXI-6529" entry
- Click the "OK" button
- Click "Reset" and observe "The device was reset successfully"
- Click "Self-Test" and observe "The self test completed successfully"
- Click "Test Panels..." to reveal test panel. Note that all configuration buttons are disabled.
- In NI-MAX, click "Settings" tab and note "Name" (in my case, it's "PXI1Slot2")
- Make a copy of C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DotNET4.5\Digital\Generate Values\WriteDigChan\CS and open in Visual Studio
- Build and run WriteDigChan
- In the WriteDigChan "Lines" combobox, replace "Dev1" with the "Name" copied from the simulated PXI-6529 "Settings" tab in NI-MAX. For me, this results in "PXI1Slot2/Port0/line0:7"
- Click the "Write" button on the WriteDigChan dialog and observe a MessageBox reporting error -200012 "Specified physical channel does not support digital output."
Does this example work for anyone else? Am I even using example code that should work?
Any advice is very much appreciated.

Measurement Studio (2019 C#) connection to Instrument Studio
Dear NI support,
Your Instrument Studio seems a software worth investigating, so I have a couple of questions:
- At the moment I’m using C# with Measurement Studio (2019) with a lot of inherited code. Your website (video) says that I can connect my C# code to IS as an out-of-process server. What can I do that way – collect data, control device parameters, or both? Is there a protocol with example code on how to do that from C#?
- Your panels (virtual devices) in IS look nice but is there a plugin standard, so I can write my own panels? In case there is: a link to the protocol would be great and some example code too (preferable C#)
- The virtual instruments are connected to the hardware via drivers (depending on device type). If In case of non-NI device and lack of a driver, is there a protocol including code examples to create such a driver (what language)?
Thank you
Theo

Reading and writing from VB.net Text boxes to network variables
Using VS13 and Latest Measurement Studio
Has anyone got an example, I have tried all day and failed.
I have a LabVIEW program as follows
I really need a VB.NET form that reads Network_Double to TextBox1.Text and writes from TextBox2.Text to Network_String
There seems to be no examples for this basic thing, they all seem to be binding from Network Variables to National Instruments components but not to native VB components.
This sort of thing must be a doddle for someone
