• How to change Teststand UI controls in the Labview example

  Hello community,

  32-bit Teststand 2014

  32-bit Labview 2015

  I'm trying to make changes to the provided Simple Interface for Teststand in Labview called first level VI.vi.

  I want to be able to make changes to the Teststand UI controls and have a difficult time.

  However, I found the brower property for buttons, I can make some changes in the style of text.

  There are a few buttons I disable and came across this link for help, but I did not fully understand it.

  I tried to use 'Ungroup by name' and 'node to invoke. However, I don't think that I did it correctly.

  http://digital.NI.com/public.nsf/WebSearch/3FE78CAEC4AD770286256E9100090900?OpenDocument

  Then I tried to rename the buttons and came across this link.

  http://digital.NI.com/public.nsf/WebSearch/530118071CD7E3B686256E89007BB16D?OpenDocument

  Also, while looking at examples of labview for teststand I noticed that it is possible to go for regular control of labview Teststand UI control. Is it interesting to watch in place?

  I want to make the interface better watch and not be able to make changes for the control of teststand UI holding me.

  Any help or examples on how to make changes to a teststand UI control would be greatly appreciated please.

  Thank you

  These buttons are buttons of ActiveX.

  To change their properties, right-click on it and select property browser...

  

  Please note that the TestStand has.  Changes may be overwritten by TestStand during execution.

  If you use a LabVIEW native button, you can use the method of the ActiveX button => don't click to start the sequence when your button is clicked.

  However, you have to take care of the other properties (such as devil when start run sequence) of your button yourself.

• ActiveX - Reg - led event reminder

  Hello

  I'm building a control for a Laser machine which based its controls in the ActiveX control technology. I had a program in c# that works, but I have because I wanted to change the settings and then connect it to another program Labview, I "translate".

  I start with a very simple operation:

  1. 'Start' ActiveX Server
  
  
  2. "load" a design for the laser.
  
  
  3. program of the "end".

  and then based on event (using the reg event reminder):

  If the "QueryStart" laser signal is activated by a switch, then "run" program.

  If the laser "starts", then light a led

  If laser 'ends', then light a led.

  I have problems to light a led by using the ref (LaserStartedLed) VI. I'm using as a model the Labview example: CWKnob to see a number from the button. But in this case, they use the numbers from the button, in my case are just Boolean, and I try to get data from common event.

  Can you help me with other ideas and corrections?

  Thanks in advance,

• How can I join buttons visible teststand keyboard shortcuts in a labview user interface

  On a normal labview VI, it is possible to configure the desired for example key navigation options assign a keyboard shortcut to a control. Is it possible somehow to assign a keyboard shortcut to the visible controls ActiveX Teststand i.eg. a basic custom user interface labview Teststand button?

  Help, please

  You may be able to do by cloning of each button, assign a shortcut to the clone, and then firing an event and call the method "DoClick' of the TestStand button - I say maybe because I can't verify the DoClick method will do what you want.

  Obviously, you can hide the clones on the front panel if necessary.

  

• Problem with ActiveX / Excel / LV7.1 in the program who has worked on an old installation of LV7.1...

  Hello

  I have a LV7.1 program that worked when ran on an old installation of LV7.1.

  I installed Office XP and LV7.1 and you can open the program without any problem.  After the opening I ctrl + shift + click on the run button to force the recompilation and the arrow becomes broken.

  All the mistakes I found are the same: invoke node contains terminal unwired or bad.

  Here is a screenshot of one of the erroneous block diagrams.  I hope that the error is recognizable.

  Only two issues I can think of are:

  1. I'm running Windows 7 - maybe the ActiveX does not work the same way?  I'm currently installing Windows XP to see if this corrects the problem.

  2. perhaps, there was an Office toolkit or something used with LV7.1 to create this program?  If so, any ideas on what it was and where I can get hold of it?

  Thank you

  Dave

  

  I suppose that the node to invoke in the picture is the node throwing the error.  Have you tried right-clicking on the refnum automation on the front panel control and a link to the ActiveX component.  If this solves the problem, it's probably the version of changing object model.

  Good luck!

• Text message sent by LabVIEW by using ActiveX controls and Internet Explorer

  
  

  MoonMan wrote:

  Well, it sure seemed like it should have worked but not luck. When I try to add FormElement with present in my VI after I wire in the reference he wire automatically changes to a regular feature.  Then he used to run because submit is not an option for item, I need to change back to click submit it.

  I don't understand, it really seems that the click should work, and it seems that the shipment must have also worked.  It was pretty easy to enter text in different areas.

  Have you tried my modified version?  Who uses IHTMLFormElement correctly.  If you then change the name of the element of 'Send Message' to 'txtmsg' (the name of the shape), it seems to work - or at least, it appears a window advertising in Internet Explorer (I have not filled in all the areas that I don't want to give my phone number or e-mail address to some random site, especially one that opens to the ad).

  When you try to change to FormElement, what measures do you take?  You change the type of the entry 'type' to the variant to the data?  You will need to right-click on this constant, select ActiveX class... and IHTMLFormElement.

  As a note of style of LabVIEW, you must close all ActiveX references that you open.  This means that any references (IHTMLFormElement, IHTMLElementCollection, etc.) need a reference close when you are finished with them.

  Again, I think sending an email is a better way to send a text message from LabVIEW, and besides, you might be able to find a better site to do.  TMobile allows subscribers to send SMS messages via their website and it seems that AT & T provides a similar service; Verizon offers a web page to send TEXT messages to their users.

  EDIT: also, the button send is not a named element (it has a "Value" property, but not a 'Name' property) so you can't get a reference to that name.  If you're exploring the output of the IHTMLElementCollection property node element, you will see that it returns a varying empty, this is why the 'click' has no effect.

• How LabVIEW can press a command button in the Access form?

  Situation: access database with a command button, which generate code after you have pressed

  Task: LabVIEW open the access database, you press the command button and read the code

  Status:

  • Use activeX to open data access - ready
  • Press the control button - open
  • code - open reading

  Problem: is there a possibility that LabVIEW automatically press the button in the Access form?

  Dear Mike,
  Thanks for the reply. You are right that MS Access is not really a database. ;-)

  When the operator will push the button, the program generates a serial number and add the new number in the article table.
  Therefore, by pushing the button means process this code.

  Solution
  After that I became the password to unlock the database, I have check the code behind the button and build it with LabVIEW.

  So it is not necessary to press the button :-)

• ActiveX control in CVI Edit substep

  I'm under CVI 2010 (10.0.1.419) and TestStand 2010 SP1 f1 (4.5.1.144).

  I came across a problem today and I know that I must be missing something easy. I am trying to create a step with a stage to change type. The lower level change called a CVI function to its module code. The CVI function opened a panel that contains an ActiveX control.

  When I try to use the lower level edit (by clicking the button in an instance of the step type), I got an error that the DLL cannot be loaded. Changing the setting of adapter CVI to run the steps in an external Instance of CVI let me see that ICB receives an ERROR of EXECUTION NO DEADLY that 'ActiveX controls cannot be created in a thread which the concurrency model is apartment multithreaded (MTA).

  I know that Edit substeps are supposed to use STA threads (there is a post of Doug somewhere around here... ah, here). So I did not know what went wrong. I created the simplest example I could think of nothing else than a control IE WebBrowser on a Panel in a .uir and still have the same error.

  More strange is that I got the error When you run one of the TestStand examples! I tried the example \Examples\StepTypes\CVI\HP34401a and got the same error:

  NON-FATAL RUN-TIME ERROR:   "c:\...\StepTypes\CVI\HP34401a\HP34401aStepType.c", line 356, col 5, thread id 0x00001694:   Library function error (return value == -176 [0xffffff50]). ActiveX controls cannot be created in a thread whose concurrency model is multithread apartment (MTA)
  

  There must be something I am doing wrong, or an option that is out of order. Any ideas?

  -J

  Change substeps are executed in a threaded so executed in the process. If you are running in an external CVI, then you will get a MTA thread. You probably don't want generally be run some edit sub-steps in a CVI outside themselves, that is why there is a checkbox "Always run in the process" on the CVI module specification table (I recommend to all developers step using CVI modules for substeps type use this setting for all of their sub-stages). Your original question was probably unrelated to the COM threading model I recommend that you debug and debug the process of with CVI seqedit.exe rather than your modules running in an external CVI.

  Hope this helps,

• Order Java button in the Web browser - PLEASE HELP!

  Hello

  I just started using LabView and I read almost every post, but I could not find what I'm looking for. Also, if I run the Vi (picture_2) I get in innerHTML indicator HTML structure for my example:

  
  
  
  
  

  Homepage | Onclick = "ExecuteAction('a.wsdl',1) START " href = "#" > START | "   Version: 2,000 Build: 20110110

  Here's where I can't find a way to press the START button with function ActiveX. I know how to simulate the position of the mouse and click mouse but I need the ActiveX function only.

  I found this function Onclick in ActiveX, but I can't make it work (do I need to write in (?) and if I need of more data in order to properly control the function.)

  Can anyone help me please with my DIF?

  Thank you

• Management of Popups in Excel using ActiveX

  I'm having a problem similar to the problem that is referenced in this post:

  https://forums.NI.com/T5/LabVIEW/handling-popups-of-Excel-while-editing-it-via-Active-X-control/TD-p...

  The difference being...

  My company has a "database" Excel that stores all our product information. At the start of my application, I read this database using ActiveX. Recently this Excel sheet has been updated to include new features by someone else in my company.

  Now, when you open this particular spreadsheet, I get this message:

  

  It does not come to the front of the screen, and unless the user realizes that it is for the LabVIEW program seems to hang up, causing the user to close the LabVIEW program, because they do not realize that LabVIEW is waiting on Excel, which is waiting on the user to make a selection on this popup.

  In the post that I quoted above, they get around this by using a knot of property with the property 'Alerts', set to false. This works to hide mistakes but doesn't seem to work for this instance.

  Is it possible, via ActiveX, to "click" the button "Update only ' without the user having to do this.

  OR

  The worst case scenario, is there a way to bring this popup forward to alert the user that Microsoft Excel requires an entry?

  Thank you

• Several Media Player ActiveX controls

  I have a system that displays video files 'live' and those historical at the request of the user. To do this, I use the Windows Media Player ActiveX controls.

  The 'live' (not really streaming, just a new video file all few seconds) display is part of my main façade, while the historical files play in a pop-up (also a VI) when the user requests them.

  Control 'live' works very well until a historic video is required and the pop-up appears. As soon as the second WMP ActiveX control appears on the screen, two of them ceases to display the video!

  They try - when either one of them has to play a file, "playing...". "appears in the status bar and reading progressive count time - but there is no video.

  The problem persists even after the closure of the pop-up window.

  No idea how to solve this problem?

  I push the files for the ActiveX control by first calling "newMedia" in an Invoke node, then put the reference that in the property 'currentMedia' of a property node. What is the right way to do it?

  (LabVIEW 8.2, WMP 10, WinXP SP2)

  Thank you!

  Hi Ian,

  I had a glance on this issue and I am unable to reproduce your problem.

  It is possible that the problem is due to a codec problem, what format are the video files? They use standard codecs?

  I built a program example runs a video the main vi and appears a second video when you press a button.

  If you change constants for path of file for videos that you use and test them using the sample program this will eliminate video formats as a problem.

  I structured the ActiveX interface slightly differantly to how you described, nor your problem however re-created method.

  Have a play with the sample program and let me know what happens.

  Best regards

• Is it possible to connect my Application ' Stop' button with the "Run" button of LabVIEW?

  Problem - one of my clients recently tested my new LabVIEW application and asked how the arrested LabVIEW application can be restarted without clicking on the "Run" (right arrow) button.

  Is possible solution - possible to connect my Application ' Stop' button with the "Run" button of LabVIEW?

  Thank you!

  Barry

  The big problem is in your Acquistion to stop audio event. You run the LabVIEW stop sign which is the equivalent of hitting the Cancel button in the toolbar.  (See contextual help on that).  You can stop the acquisition, but you don't want to stop your LabVIEW program.  You need this case in the event your computer to transition state in a sleep mode when you do not make any purchase.  Then hit the purchase button to start again transitions the machine state in the acquisition.

  In your case of program output, you want really to leave LabVIEW it.  You want to run and stop commands like closing the com port and one of these activeX references.  Then allow it to stop the while loop.  Turn the LabVIEW out outside the loop so that once everything is cleaned, your application may close.  You probably want to wrap this command in a case structure so that if you are in the execution environment, it leaves your application.  But if you are in the development environment, you don't want to cause your LabVIEW environment stop.  Another thing is that right now, you actually have a race condition in the Exit event.  The com port will close first or LabVIEW will come out.  There is no defined order of execution.

  Alternatively, you can have an event to close panel? in this way, you haven't accidentally short circuit all your program by pressing the X key.  You want to capture this event, discard it.  And if you want to not actually closed, did trigger the Exit Program button so that you can gracefully shutdown.
