• Questions about to determine the size of the array of data storage with flexibility

  I try to use the CVI function below to load data from .csv file to the table that I was intending to use later:

  filereturnvalue = FileSelectPopup ("c:\\Users\\Desktop\\FileDirectory", "*.csv", "", 'Select the data file', VAL_LOAD_BUTTON, 0, 0, 1, 0, LoadFilePath);

  FileToArray (DATAArray, VAL_CHAR, LoadFilePath, MaxDataSize, 1, VAL_GROUPS_TOGETHER, VAL_GROUPS_AS_COLUMNS, VAL_ASCII);

  For the data table "predetermined", it is quite straightforward, because the size of the table is already set.  However, I wonder if there is anyway I could use CVI directly import data and determine the size of the array on the fly?  Which means that the user need not know the length of the data, and it could be determined then to import the file.

  Hello

  for ASCII files, you can do so in any first read the file and counting the newline characters, something like:

  int file_handle;
  int index;
  int size = 0;
  char line_buffer [80];

  If (OpenFile (...) > 0)
  {
  While (ReadLine (...) > 0)
  {
  size ++;
  }
  }
  CloseFile(f) (file_handle);

  This way you can determine the number of rows you have, but you must have an idea of how long a line may be, one number per line or 32000 because you must specify the size of your line_buffer.

  In the next step you analyserions monotube for occurrence of your column separator (say a ;) to determine the number of columns (separators found + 1).

• Determine the size of each Dimension of an array of 2D in TestStand

  How can I determine the size of each dimension of an array of 2D in TestStand?  myArray.GetNumElements () refers to the TOTAL number of elements in the table (2D) and does not help me.  I need to iterate on a single dimension.

  Thank you

  Andrew

  GetUpperBounds are but just not in this context. Try something like the following...

  Locals.MyDimensions = Locals.MyArray.Type.ArrayDimensions.GetUpperBounds)

  Where Locals.MyArray represents the 2D table you want dimensions of and Locals.MyDimensions is a 1 d array to store the dimensions. Something like...

  Locals.MyArray.Type.ArrayDimensions.GetUpperBounds () [0]

  ... might work as well, this example returns the number of elements in the first dimension of Locals.MyArray.

• How to determine the size of the screen

  Is there a way in OS Version 4.3.0 to determine when executing what the resolution of the screen of the device on which the application is running?

  Thanks for the help.

  Take a look at the net.rim.device.api.ui.Graphics class

  To determine the size of the screen use the static methods:

  Graphics.getScreenWidth ();

  Graphics.getScreenHeight ();

  To determine the resolution of the screen in pixels per meter (PPM), use the following static methods:

  Graphics.getScreenHorizontalResolution ();

  Graphics.getScreenVerticalResolution ();

• Formula to determine the size of the data store

  Is there a formula or a rule of thumb used to determine the size of a data store?

  For example, if I have 10 virtual computers that will need 20 GB of disk space, how big the data store be? I know that I have 200 GB of space for real virtual machines, but what other factors should be considered when sizing the data store?

  We usually leave 15 to 20% free space on all our datastoes.

• How to determine the size the virtual machine using the VI SDK files

  VirtualMachineFileLayout a lot of files like snapshots, configuration files, log files. I have not found any object determine the size of them, but the VI Client GUI shows the sizes of them.

  Is there a VI SDK objects that provide the size of every file?

  Thank you

  RAM

  The virtual machine, you can find warehouses of data associated with (ownership of the data store). Each data store, you can find the HostDatastoreBrowser corresponding (the property browser). HostDatastoreBrowser object, you can call SearchDatastore_Task() or SearchDatastoreSubFolders_Task.

  When you call one of the methods, a task object is returned. To the success of the task, check the property info.result of the task, the object of HostDatastoreBrowserSearchResults actual result is there. Discover the FileInfo objects - they include sizes and lately of the modified files.

  Good luck.

• determine the size of the components after change

  Hello
  
  I have a little problem. I have Hbox component label inside. When I change the text of the label, hbox size is automatically changed after the code is executed. But how to know size Hbox, or size label (for example width) once after you change the text property of the label... For example...
  
  var myHbox:HBox = new HBox();
  var myLabel:Label = new Sun;
  
  now the Hbox and lablel the width and the height is zero. It is clear.
  
  Now I change:
  
  MyLabel.set_Text = "Some Long Text.
  myHbox.addChildren (myLabel)
  
  But now if I want to determine the actual size of the size of label or hbox, it is always zero.
  
  How can I determine the size at the same time, when I change the text of the label.
  
  Thanks in advance
  

  Once you have made the changes to the child components, the Flex framework through an iteration to measure children and setting the new size of the HBox.

  You have a few choices. First of all, once you set the size of the label you can do: myHbox.validateNow () and then myHbox.getExplicitOrMeasuredWidth () (there is a version of height, too) to get the new size of the HBox. This does not allow the natural process of the Flex framework to sink, but it should do the trick.

  You can also try to add an event listener for the resize on the HBox event. If changes to the child cause the HBox to have its size changed, it must trigger a resize event.

  I recommend doing this first.

• How to determine the size of the binary file data set

  Hi all

  I write specific sets of data in table in a binary file, by adding each time so the file grows a set of data for each write operation.  I use the set file position function to make sure that I'm at the end of the file each time.

  When I read the file, I want to read only the last 25 data sets (or numbers).  To do this, I thought using the position set file to set the file position where it was 25 sets of data from the end.  Math easy, right?  Apparently not.

  Well, as I was collecting data file size as I began the initial tet run, I find the size of the file (using file order size and get number of bytes so) as the size increases the same amount every time.  My size and the format of my data being written is the same every time, a series of four numbers double precision.

  I get increments are as follows, after the first write - 44 bytes, after 2nd - 52 bytes, 3 - 52 bytes, bytes 44 4th, 5th - 52 bytes, 6 - 52 bytes, 7th - 44 bytes and it seems to continue this trend in the future.

  Why each write operation would be identical in size of bytes.  This means that my basic math for the determination of the poistion of correct file to read only the last 25 sets of data won't be easy, and if somewhere along the line after I've accumulated hundreds or thousands of data sets, what happens if the model changes.

  Any help on why this occurs or on a working method, all about the problem would be much appreciated.

  Thank you

• Determine the size of the container when using SizeUnit.PERCENT

  Hello

  How can I determine the width and height of a container, when I use the percentage of the size of the container?

  I have the following code, but this.width and this.height are both 0, causing the background sprite is not to demonstrate:

     public class HeaderContainer extends Container
      {
          private var _imgCategory:Image = new Image();
          private var _lblTitle:Label = new Label();
          private var _matrix:Matrix = new Matrix();
          private var _sprBackgroundColor:Sprite = new Sprite();
          private var _tfmtTitle:TextFormat = new TextFormat();
  
          public function HeaderContainer()
          {
              margins = Vector.([5,5,5,5]);
              debugColor = 0xCCCCCC; // grey
              flow = ContainerFlow.HORIZONTAL;
              align = ContainerAlign.NEAR;
              size = MyConstants.HEADER_SIZE;
              sizeUnit = SizeUnit.PERCENT;
              initializeUI();
          }
  
          public function initializeUI() : void
          {
              with (_sprBackgroundColor)
              {
                  x = y = 0;
                  graphics.beginFill(0x0000FF, 1);
                  graphics.drawRect(0, 0, this.width, this.height);
                  graphics.endFill();
              }
              ...
          }
  

  Have you tried to call the initializeUI method after the container has been added to the scene? You can easily register a handler to do this.

• Determine the size of the component during execution

  I am trying to build a component Paginagion of size fixed. The number of pages which means that the size of the paging is fixed, however depending on the content may vary. Most do not specify how much is displayed on a single page.

  The idea is to use the text as input and push as much as can be displayed on the page. Factors having an influence here is the fonts and formatting.

  To determine the page which you should see that I need to understand the amount of text that can be displayed. To do this, I need to know the size of the element that contains the text (think label). The size of the label is however only determined after that is layouted. So here's what I could do:

      @Override
      public void start(Stage primaryStage) {
          Label lbl = new Label("uitroweigudfgf jkfhgklfsjghslkghs kflgskjgh");
          System.out.println(lbl.getWidth()+","+lbl.getHeight());
          lbl.widthProperty().addListener(new ChangeListener<Number>(){
              @Override
              public void changed(ObservableValue<? extends Number> ov, Number t, Number t1) {
                  System.out.println(lbl.getWidth()+","+lbl.getHeight());
              }
          });
          lbl.heightProperty().addListener(new ChangeListener<Number>(){
              @Override
              public void changed(ObservableValue<? extends Number> ov, Number t, Number t1) {
                  System.out.println(lbl.getWidth()+","+lbl.getHeight());
              }
          });
          StackPane root = new StackPane();
          root.getChildren().add(lbl);
          
          Scene scene = new Scene(root, 300, 250);
          
          primaryStage.setTitle("Hello World!");
          primaryStage.setScene(scene);
          primaryStage.show();
     }
  

  After the third change, I have the dimensions of the label. With this method, I would have to push all of the text in labels to figure out what can be displayed.

  Is there a better way to do it?

  My basic problem was with the size of the labels. Try to find a solution I had a look at LabelSkinBase which uses the Utils class in the same package. This class provides methods (although private package) to calculate the size of the text that results from:

  static Text helper = new Text();
  
  static double computeTextWidth(Font font, String text, double wrappingWidth) {
    helper.setText(text);
    helper.setFont(font);
    // Note that the wrapping width needs to be set to zero before
   // getting the text's real preferred width.
    helper.setWrappingWidth(0);
    helper.setLineSpacing(0);
    double w = Math.min(helper.prefWidth(-1), wrappingWidth);
    helper.setWrappingWidth((int)Math.ceil(w));
    return Math.ceil(helper.getLayoutBounds().getWidth());
  }
  
  static double computeTextHeight(Font font, String text, double wrappingWidth) {
    return computeTextHeight(font, text, wrappingWidth, 0);
  }
  
  static double computeTextHeight(Font font, String text, double wrappingWidth, double lineSpacing) {
    helper.setText(text);
    helper.setFont(font);
    helper.setWrappingWidth((int)wrappingWidth);
    helper.setLineSpacing((int)lineSpacing);
    return helper.getLayoutBounds().getHeight();
  }
  
  static int computeTruncationIndex(Font font, String text, double width) {
    helper.setText(text);
    helper.setFont(font);
    helper.setWrappingWidth(0);
    helper.setLineSpacing(0);
    // The -2 is a fudge to make sure the result more often matches
    // what we get from using computeTextWidth instead. It's not yet
    // clear what causes the small discrepancies.
    Bounds bounds = helper.getLayoutBounds();
    Point2D endPoint = new Point2D(width - 2, bounds.getMinY() + bounds.getHeight() / 2);
    return helper.impl_hitTestChar(endPoint).getCharIndex();
  }
  

  With that, I am able to determine the amount of text can be put into the label, without the chain of ellipsis appears.
