Communicate between C# window application and Labview.
Hello all!
Now what I shall do is to use both labview application and C# window application for my project. Basically it's that the state change in labview triggers an event in C#. As a short description, my labview application receives UDP message from an external device and shows them on the front panel. I'd like that when the received message reaches for example 10, the C# application is triggered to implement a switch.
I got the idea to use .Net object in labview, a constructor node to get a reference to my C# app, and in my C# app expposing public methods telling the app something happened in the LV app. I think that would help but I don't know how.
Anybody could give me an example of that. The importance for me is to know how should I set the constructor node in labview, and what is to add in C#, like "using labview" in the header.
Thanks in advance!

Once you constructed the .NET parent object (the one which provides the access to your "reaction code"), you can use invoke and/or property nodes to call into the .NET assembly.
So if your object exposes a method which should be called once you hit 10 samples, you simply count the number of samples available in LV and once 10 are available, you use an invoke node to call the appropriate method.
There are a bunch of examples provided with LV, for instance one called "Task Monitor Using .NET Objects".

I am storing a block of data inside plc registers and reading this group into labview as a continuous set of datapoints. I am counting the number of scans in the plc and sometimes the number of points collected inside labview doesn't match.
To explain a a little bit about tag updating:
The LabVIEW DSC tag engine is not just updated on any change of the value within the plc. There are, in fact, several "deadbands" that must be crossed before those tags are updated:
1) The OPC Server has a deadband - where the plc register value has to change a certain % before it is recorded.
2) In the LabVIEW DSC moduel, there is an I/O Group Deadband that determines when the tag engine is actually updated.
Both of these deadbands must be satisfied before a new "value" is recorded in the LabVIEW DSC tag engine.
Therefore, I would check your OPC Server's deadband (configurable in the OPC Server configuration utility) and also the I/O Group deadband for those tags (configurable in the tag configuration
editor).
If this doesn't resolve the issue, please let me know. Thanks. -

What is the difference between Microsoft Speech API Dsktop and Windows Runtime versions?
There is a text-to-speach funtionality on Windows Desktop and on Windows RT and Windows Phone. I want to know what is the difference of TTS APIs (SAPIs)?
Hi TIKSN,
Based on your description, it seems that you want to know the difference of the TTS APIs among the Windows Desktop and Windows Store/Phone app. If so in Windows Desktop it uses this
System.Speech.Synthesis APIs to implement the text-to-speech function. But in Windows Phone Runtime and Windows Store 8.1, it uses the
Windows.Media.SpeechSynthesis APIs to implement the text-to-speech function.
For the difference between the "Windows.Media.SpeechSynthesis" and "System.Speech.Synthesis", please try to check the reply which posted by @Rob Caplan - MSFT in here:

My photo stream has always synced just fine between my Windows 7 PC and my iPhone 5. However, just a month or so ago it stopped automatically syncing. I turned it off and on in the iPhone settings in two places, deleted all the photos manually, signed out of iCloud on my PC and even uninstalled iCloud on my PC. Now it appears to be partially working. If I add or delete photos from my Photo Stream on my iPhone, the changes are reflected on my PC. However, if I delete photos or add photos to my Photo Stream folder on my PC, the changes are not reflected on my iPhone. I can delete all the pictures out from my Photo Stream on my PC but they are all still there in my Photo Stream on my iPhone. How do I get the two devices to sync properly again?
Hello snoopy016,
Thank you for using Apple Support Communities.
For more information, take a look at:

I added some photos into My Photo Stream on my Windows PC, but they don't appear in My Photo Stream on any of my devices.
Have a nice day,

Has anyone here successfully managed to connect a LabView VI to an action initiated from within a Unity 3D developed virtual world (or game)?
I have been successful in transferring a signal from an Open Sim (think Second Life) 3D world to a LabView VI which in turns activates a robot motor.
But no luck replicating this in Unity.
Just trying my luck here :-)

It sounds like it is all about building correct interfaces between the third party software and LabVIEW.
To do that, you can look at the following link even though you may already have cheked it out.

There are differences between the two version of Office. If you need to be exactly like the Windows version, you will have to run Windows on your Mac.

Incompatibility between JDK 1.4 and Windows XP Fax and Picture Viewer
I have noticed an incompatibility between JPG files that are output from Windows XP Fax and Picture Viewer and read in by JDK 1.4 (or 1.4.1). In particular, when an image is transfered from a digital camera to a Windows XP machine, then rotated and saved in the Windows XP Fax and Picture Viewer, the resulting image file appears with corrupted colors when read and saved by the ImageIO class in JDK 1.4.
Here is my code:
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;
BufferedImage buffImg = ImageIO.read (new File ("in.jpg"));
ImageIO.write (buffImg, "jpg", new File ("out.jpg"));
I have also output the file with graphics format PNG and seen similar apparent corruption of colors.
This is an image that was loaded onto Windows XP from a digital camera then rotated 90 degrees and saved with the Windows XP Fax and Picture Viewer:
http://www.adigitalsolution.net/pics/verticalOrig.jpg
Here is the same image read and written by JDK 1.4 ImageIO.read() and ImageIO.write():
http://www.adigitalsolution.net/pics/verticalJavaOut.jpg
Note that the colors appear corrupted in the above image.
This is an image copied directly from a Sony Cybershot DSC - P71 digital camera:
http://www.adigitalsolution.net/pics/horizontalOrig.jpg
Here is the same image read and written by JDK 1.4 ImageIO.read() and ImageIO.write():
http://www.adigitalsolution.net/pics/horizontalJavaOut.jpg
It appears fine (brilliant tropical colors).
Note that both images contain the "EXIF" header, which is the JPEG-like format used by many digital cameras. Some may say that the JDK 1.4 spec does not support EXIF, but the image not touched by Windows XP was read successfully. And other image editing programs read in both successfully, such as PaintshopPro and the Mozilla 1.0 web browser. But there is a specific incompatibility with JDK 1.4.
I have reproduced this problem on Windows NT 4 and Red Hat Linux 7.3 using an image file that was saved on Windows XP.
Here is a warning from Nikon about the behavior of Windows XP Fax and Picture Viewer:
http://www.dpreview.com/news/0112/01121402nikonxpwarnings.asp
Does anybody know a workaround?This is scary and explains why some of my Exif headers are trashed.
I would guess the problem has something to do with XP not writing the file back out 100% true to the JPEG spec.
Really annoying that they do this. They think they can just hack up and change standards that are not their own. Take their FTP client in Windows XP. Talk about a broken client.
My suggestion is to dis-associate jpegs with XP's image and fax viewer. Instead associate them with Mozilla. -
Drag and Drop between two windows
I would like to implement Drag and Drop between two windows for example in Windows I can take URL Address form browser and drag it and drop it in to any control that excepts String like TextField.
I would like to have the same behavior with my Java Text Controls.
What can I do to achieve this?There is no configuration for it. It should work.
Can you try it in a different user account. If it works in a different account, then it is likely something in your current user account that is messed up. If it doesn't work in another user account, then it is likely something with Mail, itself.
You could try downloading and installing the 10.6.7 combo update. That may repair what is wrong. -
What exactly is the diff between main window and variable window
what exactly is the diff between main window and variable window in SAP script?
hi,
MAIN WINDOW :- In a main window you display text and data, which can cover several pages (flow text). As soon as a main window is completely filled with text and data, the system continues displaying the text in the main window of the next page. It automatically triggers the page break.
You can define only have one window in a form as main window.
The main window must have the same width on each page, but can differ in height.
A page without main window must not call itself as next page, since this would trigger an endless loop. In such a case, the system automatically terminates after three pages.
VARIABLE WINDOW :- The contents of variable windows is processed again for each page, on which the window appears. The system outputs only as much text as fits into the window. Text exceeding the window size is truncated; the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different form pages.
As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike. The only difference is that constant windows have the same size throughout the form.
hope this will be useful.
If useful then reward points.

Hello,
How to I increase the space between the top of tabs and the frame of the entire window? It was fine until Firefox updated and since it updated it reduced the space. Now the space is too thin which makes it more difficult to move the open window frame around when I need to grab something from Desktop. Image attached.In the image, see how thin the space is right above the tab? It was much wider before Firefox update so if any know how to make it wider again, please let me know. Thank you
