"key down" event dynamic detection called screw

Similar Questions

• key down event

  I have a question about the structure of the event.
  If you are doing an event for "key down", where can you specify which key is pressed.

  instead of any key

  It intercepts all keys.  But there are nodes on the left side of the structure of the event for the tank or scan code. They will tell you which is pressed.  You can compare it to your character or scancode of interest and if they match, run the code in a housing structure.

• [CS2/CS3] - Mouse wheel & key down events in the Listbox

  Hello, I use a dialog box to display the ListBox with the elemets. Is it possible to work arrows (up/down) to navigate in the list box, or use the mouse wheel?  I tried to connect eventHandler to dialogue and I was able to get the mouse-related events (e.g. LButtonDn,...), but my MouseWheel & KeyDown overrided method do not work?  Thanks for you answers!

  IPanelControlData-> SetKeyboardFocus(). To get the window to the front, you will need to write to platform-specific code, but look IPanelMgr - I'm not sure that the dialog boxes are part of the list window.

  In any case you do more for me sounds like something that should be on a Panel. Or maybe you need to collect the selections that the user makes in your list box and apply, when the dialog box is close. This way you can also get a button cancel in your dialog box. A few suggestions...

• Enter key down and write a simultaneous control

  I am creating a dialogue with a field with behavior such that, once the user fills in the field and press the Enter key or return the new value is returned.  However, the problem that I am running is the key down event cancels the entry to the control doesn't happen.  I can't use the event value change because the user has the choice to leave the same fair value press enter (without change).  Any ideas or suggestions?

  Right-click on the control of the 'chain' and select "Update of value while typing".

• Cannot dynamically include called subVIs in construction

  Hi, I have a VI that calls some Subvi - i.e. by reference dynamcally.

  I am now building an application and loking for this manual for help (I'm using LabView 2012):

  

  This link http://digital.ni.com/public.nsf/allkb/410F2EC66F60F9B0862569EE006F4FA0 has similar instructions:

  

  However, my problem is that I can't click on the arrows in the window. This window for me looks like this:

  

  and no arrows are clickable and no help by adding the dynamic subVIs!  For example, when the application is built, it is malfunctioning.

  Would appreciate any help you can provide on how to address the issue.

  Thanks in advance!

  Hi SensLab,

  When you use a project LV then you would be able to include all the necessary screws when building!

  BTW. Dynamically called screw should be included in the project too...

• How to determine the Boolean value selected in a mouse down event pane?

  I have a lot of Boolean controls and indicators in my VI and I would determine what boolean is selected (left click) on a mouse down event pane.  Can I do this without having to specify each of the Boolean in the case of event configuration?

  Thank you.

  Jim

  If you get a ref to your Boolean all they have properties that define it location and size. Compare the location click with the limits of each boolean and where

  Left< click=""><>

  AND

  Back to top< click=""><>

  you have found the Boolean value that ended the click.

  It may be easier to use the Boolean refs table to create a dynamic event and then use the ref returned by the mouse down to get the label of the Boolean value that has been clicked.

  Have fun

• Injection of the event to answer call waiting

  Hello

  I am trying to answer a phone call using injection of the event, I saw a few discussions about this, and it seems that the method I use is correct is a sense. I can answer a call on callIncoming, but not on callWaiting. I can answer both using the Simulator, but the device does not respond on callWaiting.

  This is my method:

  In callIncoming/callWaiting, I create a timer with a delay of 100 ms, which calls a function that sends KEY_SEND up and down events. Simple, but it only accepts a standard appeal, not an appeal pending.

  Can someone advise?

  Concerning

  Lionel

  Figured this out, increasing the timer time solves the problem.

• [C++] Events to detect changes to text in the document

  Hi all

  I use C++ to develop a plugin for InDesign. During development, I want to catch the events of changing text in the document open in InDesign. The events are something like adding or deleting certain characters or words or phrases in the document. Those can be understand that the events occurred when the user change or remove the text in the document.

  When the events are detected, they should provide what characters, words or phrases are added or removed from the document. In addition, they should provide the index of the text changes if they are able to do.

  Please help me with this problem by providing methods, functions or libraries can detect changes to text in InDesign.

  Sincerely,

  Tri Dung

  Hi Tri Dung,

  Check the API TextPreProcessService and TextPostProcessService. You can write your own services and implement the interfaces ITextCommandPreProcess and ITextCommandPostProcess.

• With the help of dynamically called screw in TestStand deployment

  I write code to interface with a & Rohde Schwarz ZNB Network Analyzer.  I use LabVIEW 8.2 and TestStand 3.5.  For reference the ZNB driver is available here: R & S of ZNB Driver.  I use a slightly older version of the driver, some before they needed to LabVIEW 2009.  I am writing all the code on a development machine that has the full version of TestStand/LabVIEW and it works on another machine that has the TestStand deployment license.

  This driver is dynamically linked to some things he needs.  I am able to operate with simple LabVIEW EXEs but not in TestStand deployments.  The following excerpt comes from their documentation, explaining a little about how the driver works and how to use in LabVIEW EXEs.

  3.4.2 How to generate executables or libraries in LabVIEW driver kernel drivers instrument based on attributes is dynamically bound to any VI performed during execution. This can be recognized by the LabVIEW application builder. The LabVIEW application builder follows all the static dependencies and include them in the package distributed at the generation of an executable file.

  To create an executable in LabVIEW, please manually add all the screws in the \PREFIX \_utility\callbacks folder to the LabVIEW project. In the case of project based please add private to your project folder. With this reference manual, the driver core is included in the compilation and the driver core is accessible during execution.

  I can't get this to work in TestStand deployments at all.  I can't even connect to the device since the VI Init has these issues.  I get the same error for all the various attempts that I made.  The same error is that when you add manually the screws for the LabVIEW EXE.

  Error-1073807346

  VISA: (Hex 0xBFFF000E) the given reference of session or the object is not valid.

  So far, I tried the following, all solutions producing this same error.  I struggled with this and turned off for awhile then maybe there are other solutions attempts I forget.

  (1) it looked like a lot of the report to go to the private folder were finished in SupportVIs.  I manually pasted the rest there, too.

  (2) I added all driver files on my workspace and included in the files with the rest of my deployed screws.

  (3) I added all driver files on my workspace and said pilot TestStand to deploy them to the original location in Program Files.

  Someone at - it ideas?  R & S didn't even know what was TestStand, so that they could not help me.

  I was finally able to solve this problem on mine, the other day.  I brought the Network Analyzer to my office and did a lot of tests in this way.  Eventually, I discovered that I needed to include the folder private pilot deployment, what I was doing in one of previous attempts.  It turns out that you must also maintain the original of this file directory structure when you include it, otherwise dynamic calls are not looking in the right place.  Once it worked on my PC, I got it on the machine test and worked as well.

• Combine events "Key Down" and "ValueChange?

  Hello

  I have a string control box where a bar code is entered. I want to discover two events that should trigger the same action:

  Event 1: Loss of Focus (= change value)

  For example, someone focuses on the channel control unit and changes a number, and then puts the focus (without pressing). At the time where the focus is more, this event is raised.

  Case 2: Enter"" key.

  In any time you press the key "enter" in the area of control of chain. I can filter Vcle to check whether or not it is the "enter" key. For example, a user could bring out the code bar and press ENTER to specify the barcode must remain unchanged.

  My problem is, I need to trigger the two events, but only once.

  If I have two events separate case, 2 event will raise also 1 event, so my action will be spooled twice. Not good.

  I'm not yet sure how to combine two cases of event in a unique event, which triggers only once on 'enter keypress' or "lost focus, change the alias value". Any suggestions?

  See below. Thank you!

  

  Switch to dynamically registered events:

  

  Note that you must pass the dynamic events in the event sources list:

  

  Then, after each event, unregister and then register again for events.  If there was an event in the queue's duplicate, this will destroy it.

• Drop-down menu dynamic - "initially selected.

  Would appreciate some advice here because I can't find a solution

  I have some MySQL tables in a database that I use with PHP to make a billing page based on the web that retrieves data from other tables based on selections made using dropdpwns.  Using an "onChange" event handler, make one selection (other than one already shown dependent) calls a Javascript function that queries a database through a PHP page called. Then fill another predefined with the query results.

  For example: -.

  • the user makes a selection in the drop-down list of 'Product ID' (this is filled using dynamic data to a products table)
  • Once the selection is made, the javascript and PHP work to fill another area of the page with the result returned.

  Now the problem I have is that when loading the page, the 'initially selected' on the dynamic drop-down list shows the last entry of the table.

  Sorry to take if long development, but here goes...

  What I want to achieve is the loading of the page, dynamic drop-down menus are filled with the data in the table, but each has then a "select..." rather than the last record in the table display. "  This requires the user to make a change.  This is necessary because the "onChange" event handler must be changed so that it calls the function.

  Is there a way to do it, or am I barking the wrong tree, so to speak.

  Would appreciate your collective knowledge.

  Thank you very much

  First of all, in the dynamic dialog where you select the table and assign the value and labels, delete anything that may be in the text box set the value below. This is used to display a previously selected value that is part of a Recordset or another value. Then, add a static selection option above - all you need is a text as you please select and the value can be left blank. Save, then highlight the static label and make it like the option chosen initially. You will need are also posting to make a required selection. List of menus is the rule that you need something formulated thing lik "first step". Given that the first option is the static label, please select, the user cannot use it as a selection and validation will fail. The effective implementation of the validation of the form varies depending on what you are using, as some ther are built in DW, Spry validation more several third party extensions, you can use the functions.

• Satellite A300D - FN keys and fan not detected

  Hello

  Crashed my HDD (winlogon, MBR, boot,... deleted. Just a disaster), so I have to format the drive and make new instalation of Windows. And it happened Toshiba utility installation. And I can not find the drivers for the FN key. I googled to be called "Utility Flash Cards", but only what I founded is pdf of it. And also my Everest or Notebook hardware control is none of my fans.

  So I ask, where can I find it? Or better... is a place of grand ' ol pack after the new installation of the operating system? Why my fans are not detected by the system? Maybe I just forgot to install a driver. It is quite possible. So, where is a problem?
  And... I'm just curious, y at - there a programe, utillity... etc. which can control the fans?

  I have the Satellite A300D, Windows Vista 32-bit

  Thank you very much!

  Hello

  Can on mate, you can find all the drivers and utilities on the Toshiba site:
  http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

  You must install Toshiba Value added Package. That's all that you need for the FN keys. ;)

  But I m wondering about your question about the fan. Why do you think the fan isn't recognized? Everything about the fan will be controlled automatically. You can change only the method of cooling between performance and battery optimized in Windows power management.

• How to make the difference between the mouse down events in the control of the chain (click on contour vs click Center)?

  Hello

  I have a control over the chain on my UI and I would like to make the difference between mouse different events, that is to say, to be able to differentiate a click on the outline or the label of the controller vs right-clicking on the Center (between the control in "edit" mode)

  The reason is that sometimes if the user does click not in the Center but in the scope of control, Labview fires the mouse event down but the typed keys are not registered...

  Is it possible to distinguish the two?

  Thanks a lot for your help

  Set the string "update as you type" and use instead a "changed value" event Now, the event fires whenever a new character is entered.

• Dynamic action calling JavaScript with parameters

  I have a DA who called some JavaScript to Hide/Show/cancel 2 P110_PARENT_SOLUTION_ID text elements, P110_ANSWER_TEXT be part of radio P110_DIRECTORY_TYPE.

  DA > settings > Code:

  If ($v ("P110_DIRECTORY_TYPE") == 'R') {}

  $("label[for=P110_HEADER_TEXT]").text ("name of the root directory")

  $x_Hide ('P110_PARENT_SOLUTION_ID');

  $x_Value('P110_PARENT_SOLUTION_ID',"");

  $x_Hide ('P110_ANSWER_TEXT');

  } ElseIf ($v ("P110_DIRECTORY_TYPE") == 'E') {}

  $("label[for=P110_HEADER_TEXT]").text ("header text")

  $x_Show ('P110_PARENT_SOLUTION_ID');

  $x_Show ('P110_ANSWER_TEXT');

  } ElseIf ($v ("P110_DIRECTORY_TYPE") ==' no) {}

  $("label[for=P110_HEADER_TEXT]").text ("directory name")

  $x_Show ('P110_PARENT_SOLUTION_ID');

  $x_Hide ('P110_ANSWER_TEXT');

  $x_Value('P110_ANSWER_TEXT',"");

  }

  This works perfectly, however I need to reproduce this code for 2 more areas on the same page. To do this, I created a JavaScript function with 3 parameters and call it in the dynamic action

  Page header > Javascript > function and Global Variable declaration:

  function ProcessDirType

  (I_DirectoryType

  I_ParentSolutionId

  I_AnswerText

  )

  {

  If ($v (I_DirectoryType) == 'R') {}

  $("label[for=P110_HEADER_TEXT]").text ("name of the root directory")

  $x_Hide (I_ParentSolutionId);

  $x_Value(I_ParentSolutionId,"");

  $x_Hide (I_AnswerText);

  } ElseIf ($v (I_DirectoryType) == 'E') {}

  $("label[for=P110_HEADER_TEXT]").text ("header text")

  $x_Show (I_ParentSolutionId);

  $x_Show (I_AnswerText);

  } ElseIf ($v (I_DirectoryType) ==' no) {}

  $("label[for=P110_HEADER_TEXT]").text ("directory name")

  $x_Show (I_ParentSolutionId);

  $x_Hide (I_AnswerText);

  $x_Value(I_AnswerText,"");

  }

  }

  DA > settings > Code:

  ProcessDirType

  ("P110_DIRECTORY_TYPE"

  , "P110_PARENT_SOLUTION_ID".

  , "P110_ANSWER_TEXT".

  );

  Her DA stopped working correctly, I tried to replace the parameters with single quotes but not joy.

  Can someone give me the correct syntax so that I can make my code more generic and call in three different DA?

  
  

  Concerning

  ADE

  I didn't think there would be syntax errors, everything looks good from here. Single or double quotes can be used.

  Maybe it's something to do with the way in which the dynamic action is called. Is what event listening? Nothing has been changed in order to manage several regions?

  You can add this sort of thing to your javascript to help determine what is invoked and view the output in the javascript console.

  console.log('I_DirectoryType:'+I_DirectoryType);
