flicker of the cursor when you close or flushing a file

I write about a timestamp to a file each time in a loop in my main program (to save during the last of data analysis).  I do this so that if the program stops when it is restarted, it can say how long the program has been down for.

Anyway, if I write/open/close the file on each loop, I get a flicker of the slider (the normal cursor to an hourglass).  If I simply open the file on the first call and simply write the file on each loop, I don't get a flicker.  But then I need to empty the file on each loop to make sure that data gets written.  Can I get the flicker when Flush is called.

I tried this, use a datalog file and a text file.  Is there another file that I could use that would not cause this behavior?  Or is there a way to prevent the modification of the file IO screw slider?

Found out what the problem was.  The data file I wrote for was in my LabVIEW project.  So I guess he tried to update the project whenever I updated the data file.  Once I deleted the file from project data, everything was fine - no flicker hourglass on the slider.  Thanks for all the answers.

  • Why you put "Open a new tab" on the right side of the browser, when you close a tab on the left and you type a new URL in the browser on the left?

    I changed my computer from XP to Windows 7 and migrated my FF browsers. But... now the tabs at the top of the page are all right (they were upper-front left - where I loved her)

    The most important is the "open a new tab" + - is on the right. But that is not sensible. Why you put "Open a new tab" on the extreme right of the browser, when you close a tab on the left and you type a new URL in the browser on the left?

  • Problems with the cursor when you type

    I don't know if it's something in Vista, but I have terrible problems in Word and when typing emails. I can touch type and normal type without looking at the screen. However, I find when I look at the screen, the cursor inexplicably himself stuck about4-6 rear lines and hit the last piece in the middle of the existing text. In fact it just happened again - when I type ing he climbed to the title: why!

    I feel responsible because I don't get it in the older microsoft software that I use at work and it has never done in internet cafes - didn't have it a few months, but it drives me crazy: why it does this?

    Patjom, make sure that you do not have to hide when you type the value of the mouse pointer. Here are the steps:

    Open mouse by clicking the Start button, click Control Panel, clicking hardware, and then clicking on the mouse.

  • How I have a lively symbol follow the coordinates of the cursor when you click it?

    Similar to this example: http://forums.Adobe.com/thread/1162104

    I can't find the simple code to make my cursor play a symbol where the cursor is. I'm doing a Brush tool that changes colour and fades with time, like chem-routes colors in the sky.

    Thank you!

    Hmm.

    How to use createChildSymbol?

    http://Ciruelo.jp/js/edge/CS/cursor2.html

    1: create a symbol called "Symbol_1".

    2: Add this code on Symbol_1 - Timeline.complete.

    //delete this instance when timeline complete.
    sym.deleteSymbol();
    
    

    3: Add this code to document.compositionReady.

    //on/off mousemove event handler method
    sym.$("Stage")
      .mousedown(function(){
        sym.$("Stage").on("mousemove",draw);
      })
      .mouseup(function(){
        sym.$("Stage").off("mousemove",draw);
      });
    //create instance of Symbol_1 on stage.
    function draw(evt){
      var instance = sym.createChildSymbol("Symbol_1", "Stage");
      instance.getSymbolElement().css({
        position:"absolute",
        top:evt.clientY,
        left:evt.clientX
      });
    }
    
    

    The basic method is like that. If you want to adjust the pos of the instance, number of instances, etc...

    Calc evt.clientX and evt.clientY, record the number of instances, calc distance between the instance that created before and so on.

    Good luck.

  • Lose the italics of the word when you are exporting FrameMaker 11 files

    When I import a Word file into image - the italics and boldface are maintained. But if I save the file as HTML or XML - that they disappear. If I retag them with character tags, they are maintained, but work in a science paper the italics are everywhere. Is it possible to find the italic origin and replace with label of character?

    I use FrameMaker 11.

    Are applied in the form of tags in Word character attributes or are they fair substitutions? Check the FM file to see if the items in italics and bold character applied tags. If this is not the case, use the search/replace to quickly label elements.

    1. first create the appropriate character tags.

    2. apply the tag to a single instance.

    3. use the copy > special to pick up the tag of characters to the Clipboard.

    4. use find it > Format characters to find the attribute setting in the shape you want to tag (SHIFT + F8 sets at AsIs ensure you selectt only Hat properties that you need to look for, i.e. italic or bold).

    5. use by gluing... option in the change for you apply character tag to all instances found.

  • When to use the cursor for loop and the cursor (open, fetch, close)

    Hello world
    I have a small doubt about when to use the cursor for loop and when to use the cursor for loop and the cursor (open, fetch, close).
    Well, I'm not the difference between implicit and explicit cursor. So please tell me how I got to know, what to use and when?

    All SQLs are analyzed, stored and executed as cursors. Thus, you will always use a cursor.

    The problem is that languages, such as PL/SQL, provide different interfaces to interact with the SQL cursor. As the ref, the slider interface, the interface DBMS_SQL slider interface and so on.

    Each of these interfaces offers different features. For example, using the interface DBMS_SQL allows binding dynamics and dynamic recovery. The Ref Cursor interface allows your code PL/SQL pass a handle to a reference pointing to the SQL cursor, to an external client. Etc.

    The fundamental reason for the use of an explicit cursor interface is mainly that you own and manage bulk made extraction output provided by PL/SQL cursor.

    With a cursor FOR , the motor loop of PL/SQL optimize the loop by extracting block a 100 lines both. However, you cannot access this collection in bulk directly inside the loop.

    With an explicit cursor interface, you specify the size of the extraction in bulk via the clause LIMIT , and you set the variable of collection to use. This allows you to use the collection directly variable inside the loop.

    However, the need to do - code manually in bulk collection - rarely occur in the daily programs in PL/SQL. A line of treatment is both slow and not well fits. And even if your bulk code collects lines, these lines must still be processed one at a time in your code. It is much more efficient and scalable rather write SQL code, and make the engine SQL the line of treatment for you.
