• How to get the property of the image on the width and height?

  Hi, all, I import image from the outside with the following method, but how to get the w3c_main.png on the width and height property? I will appreciate for your answer.
  
  var mcLoader = new MovieClipLoader()
  mcLoader.loadClip (" http://www.w3.org/Icons/w3c_main.png", image);
  
  or an image. LoadMovie (" http://www.w3.org/Icons/w3c_main.png")

  in the first case use the method onLoadInit() to a listener for your mcl before trying to access your target movieclip laborious and _height properties.

  in the second, use the preloader code to ensure your png loading is completed before attempting to access the _width and _height of your target movieclip properties image.

• How to get the Subvi (the virtual path is in .exe) reference in Run Time System

  Hello world

  The problem is how to get the reference of the Sub - VI in run time system, when the Subvi is in .exe after construction.

  More details:

  Top of page vi called the Subvi dynamically, so that the Subvi is always included, and the source object is the application.exe.

  After the above configuration, the Sub - VI will be the application.exe. For example, the path of Subvi est...\application.exe\SubVI.vi

  So, how to get the reference of the Subvi in Run Time System?

  I can't do it when you use 'open reference VI' with le...\application.exe\SubVI.vi path in the run time system.

  In fact, I can create a file to include the Subvi, rather than build the Subvi in application.exe, then I can get the convenintly reference. But this isn't my favourate average.

  Thank you

  That is the problem. Call a Subvi dynamic means users could change, but it is also very attractive.

  The dynamic call should be used in a user control, but some parade can avoid problems.

  It depends on why you use dynamic calls...-online 2 main ways:

  -Dynamic call are used to maintain a scalable framework for the code without acting on the executable file-online a single VI distribution managed by the administrator/developer

  -Dynamic call are used to provide a collection of "external" characteristic that could be enriched by the administrator/developer. For example, you provide your customers a set of selectable custom signal filters in the executable.

  In 2 cases, you are only able to assess the skills of the users to know if there is a risk of damage, if there is a change.

  So to stay only master a parade might be to provide dynamic VI without a schema, but with the problem of maintenance, since no in-place editing and more attention to manage distribution.

  Another way is to hide the actual distribution to user-online call dynamic VI but it without name as *.vi but others (a repellent name as system of OS name ) or simply without extension in order to attract not user... but that's debatable...

  Another more difficult but more secure method is to create a consistency check before your routine (version, user, modified date,...)

• How to get a reference to the delivery of the program (not at base of LV)?

  Hello

  I need to create a LV application which will be:

  -Run external executable and not on LV. It has a window of the UI which will open

  -Open PS (no title, menus, etc.) and position it under the user interface

  -If the user moves main UI, LV app FP follows the window

  -If the user closes the main user interface, LV app closes and ends.

  App - LV does not display in the bar of tasks

  So, basically, I need to develop an application that will add-on to an existing GUI, so that together they look and behave like a single user interface.

  The main thing I am struggling with now is how to get a reference to the execution of UI that I call using the exec.vi system

  Help, please!

  What operating system? If you are on Windows, you can try to use the Windows API. Specifically, FindWindow to get a reference to both windows and SetParent to set the parent of one of the windows. This example gives you the basic idea.

• How to get the bar display of title in pixels text length?

  Hello

  Does anyone know how to get the length of the title bar text (in pixels) display?  Just to clarify, that's what I'm looking for:

  

  I don't see a CVI function for this.  The attribute ATTR_TITLE_FONT for GetPanelAttribute (...) is only valid for the panels of the child which prevents me from using the GetTextDisplaySize (...) to get the size.  Dive into the Windows SDK I can not even find an answer here.  Any ideas?  Thank you.

  Figured out how to do this.  Go to the SDK to get the font properties - is kind of nonobviousness.  But once you have the font properties, you can create a font of meta in CVI, with properties, and once you have the meta font you can use GetTextDisplaySize (...) to get the size.  For any future reference:

  //define a NONCLIENTMETRICS structureNONCLIENTMETRICS ncmtest;//We have to set the cbSize parameter to the size of the passed structure before retrieving it
  ncmtest.cbSize = sizeof(NONCLIENTMETRICS);
  //Get NONCLIENTMETRICS structure
  result = SystemParametersInfo(SPI_GETNONCLIENTMETRICS, 0, &ncmtest, 0);
  
  //copy the title font name to a c-string
  while(ncmtest.lfCaptionFont.lfFaceName[i] != 0)
  {
      thefont[i] = (char)ncmtest.lfCaptionFont.lfFaceName[i];
      ++i;
  }
  
  //null terminate
  thefont[i] = '\0';
  
  //create meta font with title font properties.  lfWeight & 0x700 indicates bold.  CreateMetaFontWithCharacterSet() doesn't recognize DEFAULT_CHARSET so we replace it with VAL_NATIVE_CHARSET(?).
  uir_status = CreateMetaFontWithCharacterSet ("TheTitleFont", thefont, abs(ncmtest.lfCaptionFont.lfHeight), ncmtest.lfCaptionFont.lfWeight & 0x700 ? 1 : 0, ncmtest.lfCaptionFont.lfItalic, ncmtest.lfCaptionFont.lfUnderline, ncmtest.lfCaptionFont.lfStrikeOut, 0, ncmtest.lfCaptionFont.lfCharSet == DEFAULT_CHARSET ? VAL_NATIVE_CHARSET : ncmtest.lfCaptionFont.lfCharSet);
  
  //get titlebar text
  uir_status = GetPanelAttribute (panelhandle, ATTR_TITLE, thetext);
  //get title bar length
  uir_status = GetTextDisplaySize (thetext, "TheTitleFont", &height, &width);

• How to get the text of a SystemPrompt (Cascades)

  Hello

  I've been struggling with this for a few hours now. I followed the example of "dialogues" on github, so I have successfully created a SystemPrompt (the dialog box that allows the user to enter text and accept / reject). Curiously, in this example there is no use of user text input. Do you know how to get the text in my QML? Here you have an example of code that I use:

  My QML:

  // Default empty project template
  import bb.cascades 1.0
  import bb.system 1.0
  
  // creates one page with a label
  NavigationPane {
      id: navigationPane
      Page {
          attachedObjects: [
              SystemPrompt {
                  id: prompt
                  title: qsTr("Enter a text for the label")
                  modality: SystemUiModality.Application
                  inputField.inputMode: SystemUiInputMode.Default
                  inputField.emptyText: "Label text..."
                  confirmButton.label: qsTr("Ok")
                  confirmButton.enabled: true
                  cancelButton.label: qsTr("Cancel")
                  cancelButton.enabled: true
                  onFinished: {
                      if (result == SystemUiResult.ConfirmButtonSelection) {
                          lab1.text = ????? // Here is where I don't know what to do
                      }
                  }
              }
          ]
  
          Container {
              layout: StackLayout {}
  
              Label {
                          id: lab1              text: "Label text"
                  objectName: "lab1"
                  textStyle.base: SystemDefaults.TextStyles.TitleText
                  horizontalAlignment: HorizontalAlignment.Center
              }
  
              Button {
                  text: "Update label"
                  horizontalAlignment: HorizontalAlignment.Center
                  topMargin: 150.0
                  onClicked: {
                      //_appUi.editLabel();
                      prompt.show();
                  }
              }
          }
      }
  }
  

  Be sure to add this in your .cpp file or all of app:

  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  

  and don't forget to include them in your app .cpp file (probably not all are needed, but just in case I leave here for the moment):

  qmlRegisterType("bb.system", 1, 0, "SystemUiButton");
      qmlRegisterType("bb.system", 1, 0, "SystemUiInputField");
      qmlRegisterType("bb.system", 1, 0, "SystemToast");
      qmlRegisterType("bb.system", 1, 0, "SystemPrompt");
      qmlRegisterType("bb.system", 1, 0, "SystemCredentialsPrompt");
      qmlRegisterType("bb.system", 1, 0, "SystemDialog");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiError", "");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiResult", "");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiPosition", "");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiInputMode", "");
      qmlRegisterUncreatableType("bb.system", 1, 0, "SystemUiModality", "");
      qRegisterMetaType("bb::system::SystemUiResult::Type");
  

  Thank you very much

  If you look very carefully by the docs, you'll trip over https://developer.blackberry.com/cascades/reference/bb__system__systemprompt.html#inputfieldtextentr...

  So, replace your? with inputFieldTextEntry() and you will get the text you need.

• How to get the time of the device

  Hello

  I'm developing an application in which I send location of the device in lat, long for every 10 minutes.  I want to send some time also with lat, long. This time must be peripheral situation updates for every 10 minutes.  Can someone tell me how do I do this?

  It is not obvious to your OP exactly what you ask.

  Ask you in a certain way a consistent recording time no matter what time zone are you in?

  Or are you just asking how to get the date and time?

  If it's the last QDateTime is one of the ways to get the date and time...

  http://developer.BlackBerry.com/native/reference/Cascades/QDateTime.html

  If you ask for the first answer more complex, you will probably need to check the time against an external clock (say GMT) and then re-reading use the contact information you have saved to determine what the weather was (including a calculation of DST) at this point in this particular time zone.

  Relying on the phone to change accurately that it is time that you move in time zones will not give accurate results.
