  • How to clear the content of a bitmap

    I created a bitmap that contains the contents of a charger.

    I want to clear the contents of the bitmap image whenever the loader loads an image.

    Here is the code:

    var theContent:Bitmap;
    
    function display(xml:XML):void
              {
                   var provider:DataProvider=new DataProvider();
                   for(var i:int=0;i < xml.shape.length();i++) 
                   {
                        provider.addItem({label:'image '+(i+1).toString(),source:xml.shape[i],data:i}); 
                }
                   collection_shapes.direction = ScrollBarDirection.VERTICAL;
                   collection_shapes.dataProvider = provider;
                   collection_shapes.columnWidth = 100;
                   collection_shapes.rowHeight = 100;
                   collection_shapes.columnCount = 2;
                   collection_shapes.rowCount = 2;
                   collection_shapes.addEventListener(Event.CHANGE, select_img);
              }

                   e.target.selectedItem=null;
              }
              function viewImage(n:int):void
              {
                   shapeLoaderArr[selectedRestricted].unload();
                   shapeLoaderArr[selectedRestricted].load(new URLRequest(xmlData.shape[n]));

                   shapeLoaderArr[selectedRestricted].contentLoaderInfo.addEventListener(Event.COMPLETE, on_shape_complete);
                   
              }
    
    function on_shape_complete(e:Event):void
              {
                   theContent = null;     //it dosen't work.
                   theContent = e.target.content;
                   theContent.x-=theContent.width/2;
                   theContent.y-=theContent.height/2;
                   
                   view_mcArr[selectedRestricted].addChild(theContent);
                   view_mcArr[selectedRestricted].width = 70;
                   view_mcArr[selectedRestricted].height = 70;
                   view_mcArr[selectedRestricted].x = this.restrictedArr[selectedRestricted].x;
                   view_mcArr[selectedRestricted].y = this.restrictedArr[selectedRestricted].y;
                   this.restrictedArr[selectedRestricted].addChild(view_mcArr[selectedRestricted]);
              }
    

    Please help me solve the problem.

    If the content is the content property of your loader that loads a bitmap, use:

    function on_shape_complete(e:Event):void
    {
    Bitmap (content). BitmapData.Dispose ();
    content = e.target.content;
    theContent.x = theContent.width/2;
    theContent.y = theContent.height/2;

  • How to clear the contents of my old iPad without also erase it from my other?

    I backed up my new iPad Air2 use iCloud and now want to delete all the contents of my old iPad. How can I do this without also deleting the content of my new iPad?

    Manipulation of content on the old iPad will not affect the content on the new iPad

    Following the instructions here should take care of it

    What to do before you sell or give away your iPhone, iPad or iPod touch - Apple Support

    Explanation: I am usually concerned about things such as notes and images - but if they are on the new iPad - and that is synchronized in the cloud, then signing of iCloud on the old device will not affect anything

  • How to clear the contents of a file

    Hello

    I have a file that includes some characters written in it, I want to delete the file, how can I do this?

    Say that I called "LabVIEW" Word, I need to erase this word and end result should be the empty file.

    I need to replace the content by writing "OR" in the file, but when I do this I still find other characters of the word of LabVIEW.

    Thanks in advance

    There is a difference between your method and mine. My method will move the EOF marker so that it gets placed after all what I have written in the file, which in this case is the empty string. With your method the EOF marker is not moved. To perform the equivalent operation with your code, you will need to use the right to set file size after the write function to set the file size to the length of the string that you wrote in the file. Or, you can use the unique feature that I did.

  • How to drive the content of a text field or table from a drop-down list selection cell?

    Users will choose an option in a menu drop-down. I want their selection to control the contents of the cells in a table or text elsewhere on the form fields.

    For example, 'The coldest season of the year' by selecting 'winter' in the menu drop-down displays in a table cell.

    Thanks in advance for the help.

    Hi Nick,

    Here are some examples:

    https://Acrobat.com/#d=pxtis4z3OxCqWxajZwDS2Q

    https://Acrobat.com/#d=20lQl9JfL19aBtbPC1WYbw

    https://Acrobat.com/#d=Hi0ZwVgVB1PWbxc6OJ0z4A

    If you open these in LC Designer, you can view the script by selecting the menu drop down and looking at the script at the top of the window Editor. If the script editor is a single line, you can drag the lower edge to make it bigger.

    Good luck

  • Display the contents of a text file in the control of the chain without changing the format

    Hi all

    I need your help!

    Planning the content of the text report file in labview control chain of the GI.

    When I read the text file and update the chain control, alignment of text was not appropriate.

    but when I open the same text file in Notepad, alignment looks good.

    How to solve this problem of text alignment?

    Gramy

    You experience the same problem before.

    Just use a .net textbox control to display text, instead of the string of LabVIEW.

    There is NO need to re - format the string.

  • How to find the largest number of text file

    I use the "Read from the text file" block to read the data in my .txt file in labview.  It is now in the string format.  I have a lot of numbers in the file.

    For example:

    0.45

    0.35

    0.12

    1,354

    1.56

    2.89

    5.89

    0.56

    That's what might look like a text file.  I want to find out which of these numbers is larger and do calculations with this number.  I have problems with channels/number/berries formats, etc.  Thank you

    Try to read that the file with File.vi reading worksheet with transposes the True value. Then use the table Max & Min to get the biggest number in the table.

  • How to clear the contents of a cube

    Hello. How can I completely erase the data in a cube, preserving the sketch?
    Note that I do not mean substituting values with zeros, because I need VALUES LIST and no zeros.
    Thanks in advance.

    Do you mean completely erase a database?

    You can do this via EAS by right-clicking on the database and selecting 'Clear data'-> 'all data '. This will erase all the data and keep the outline, calc scripts, etc..

    You can use MaxL alter reset database for ASO bases and BSO.

    Or do you mean deleting selective bits of a data base, using something like CLEARBLOCK (BSO) or CLEARDATA calc script commands? In the land of the ASO, you can use MaxL clear aggregates of database change or delete order data from the region.

    Kind regards

    Try this then and you can replace the blur with an event of jquery as you like

    $("#P16_ENG_CTRY").blur(function() {
    //clear the value
      if ($(this).val()==null || $(this).val()=="") {
         $("#P16_ENG_STATE").val('');
      }
     }
    });
