• How can I limit the number of rows in a text input field?

  I don't want to have it scrolling. For example If the field has four lines the user is writing the fourth lineand give such ENTER or continue type up to are no longer on this line, I don't want to create in the fifth line text field. Il a do?

  An approach here is to limit the number of lines, someone else might have a different approach... "tf" is the name of the instance of the textfield object.

  tf.addEventListener (Event.CHANGE, checkNumLines);

  function checkNumLines(evt:Event):void {}
  If (TF.numLines > 4) {/ / deletion of the last typed character}
  TF. Text = String (tf.text).slice(0,tf.length-1);
  }
  }

• Limit the number of characters in a text based on the first digit field

  Hello and thank you in advance for your help!

  I want to limit the amount of characters in the text field based on the first digit of the number (the text field is limited to a number format... no decimals, no comma).

  For example, if the number starts with a 3, I would limit the text field to allow only ten characters. I have three scenarios but if I could start with code and what is the best place to add (key combination or validation?) I can take it from there. Thanks again for your help!

  I wrote this code for you that does this. Use it as a typo of the custom field code:

  // Validate that only digits are entered
  if (event.change) {
      event.rc = /^\d+$/.test(event.change);
  }
  
  // Validate string length if it starts with 3
  if (/^3/.test(AFMergeChange(event))) {
      event.rc = AFMergeChange(event).length <= 10;
      if (!event.rc) app.alert("If the number starts with \"3\" it may not be longer than 10 digits.",1); // optional error message
  }
  

  You can duplicate the second part of it for additional terms, but keep in mind that this code won't let you even remove the first character in the field if the result is not valid.

  For example, if you enter "234567890123456" then you can't remove the "2" at the beginning because that would result in a number not valid. You can delete all the other numbers, even if and when it is 10 digits or less, then you can remove the departure "2" as well.

• Can I limit the number of lines of text entered into a TextArea?

  Hello

  I use Flex Builder 2 to create an application that allows users to enter text in different TextAreas and eventually create a PDF file with their different text. My only problem is that I can't limit the number of lines of text used in each text box. I can limit characters by using maxChar, but this does not take into account a user entering multiple presses "return" - this does not affect the character limit, but can result in the final PDF layout (spitting the text on page 2).

  Is there a way to keep track and limit the number of lines of text in a text box (in Flex 2)?

  (Ideally I won't disable the ability for users to use the 'back' button to create several paragraphs)

  Any help would be appreciated.

  Thank you

  Ben.

• Zoom in French - to the acrobat reader do not reduce the number of words per line to fit screen

  Zoom in French - to the acrobat reader do not reduce the number of words per line to fit as screen micorsoft Word knows to extend this feature is the free acrobat reader - or only exist in a paid product Adobe - and how is - this product called from adobe on its less expensive way for Windows 10 .it.

  You don't ask to convert to word. You seemed to ask if you could zoom in on a pdf document and have the text reformatting "As Microsoft Word can do". The answer is higher. Drive abyy fine will not redistribute the text either. Is neither Adobe Acrobat

  But you touched kind on your answer. With ExportPDF or Adobe Acrobat, you can convert the PDF file to a Word document that will be redistributed as you want. But this is not a pdf file. It will be a Word document.

• Limit the number of characters on the Master Page?

  language: php

  Question: In regard to the master page, does anyone know how to limit the number of characters to display only 250 in Dreamweaver CS4?

  That is easily fixed. Use this custom instead of the function:

  function extractChars($text, $chars = 250) {
       if (strlen($text) < $chars) {
            return $text;
       } else {
            $pos = strpos($text, ' ', $chars);
            return substr($text, 0, $pos) . '...';
       }
  }
  

  Put this function definition in your page and use it like this:

  echo extractChars($row_recordsetName['fieldName']);
  

  If the text is less than 250 characters, you will have just the full text. If it is more than 250, you get the shortcut text.

  The function has an optional second argument, which determines the number of characters you want to use as a boundary. So, if you want only the first hundred, follow these steps:

  echo extractChars($row_recordsetName['fieldName'], 100);
  

• Need to limit the number of columns

  When a tab in the last cell of the row, I want the cursor to the next line down. Instead, it creates a new useless column. Can't seem to find a setting that allows me to limit the number of columns in a page - someone ' one knows how to do this?

  Thanks for your wisdom shared, Oh wise Ones.

  I'm not aware of do what you want.  You can post your comments directly to Apple using the menu item "numbers > provide Feedback numbers.

  You can still use the key combinations:

  < command > + < right arrow > to access at the end of a line

  < command > + < left arrow > to move to the beginning of a line

  < command > + < down > to pass at the end of a column

  < command > + < arrow > to move to the beginning of a column

• How can I limit the number of attempts to print a web page

  I am trying to find a solution to a problem on our network.
  We run several kiosk machines that allow customers to print documents and web pages. However, we find that we are wasting a lot of ink because of the user frequently sending the same print job on the printer.
  Yesterday we had someone print more than 70 pages, because they just keep clicking on print.
  I tried looking for an add-on that would solve this but was not able to find one.
  My question is this, is there an internal setting that can be changed in firefox to limit the number of prints is trying to say once every 30 seconds, or even a way to make a dialog box turns on screen saying that the print request is currently dealing and does nor print before completing the task at hand.

  Sorry, there no setting in Firefox to avoid that from happening. Once the user sees the "native print dialog" box (which is seen when you Ctrl + P for print), the operating system and the printer drivers are here.

  I saw something similar to that on kiosk / PC rental stores Office of FedEx, which inform the user of the cost per page, the user wants to send to a printer, and when the user click again to the same pages again, he asked if you want to spend another $x.xx to print a second copy. Would not too different to simply cut the printing of multiple copies of the same document and warn the user of this action.

  My advice is to discuss it with anyone who put in place these kiosks to be with.

• How can I limit the number of Web sites on the new tab page?

  Is there a setting where I can limit the number of thumbnails / Web sites that appear on the new tab page? When I opened a new tab - I don't want to see tons of sites I have visited - but also, I don't want to delete them all. For example - there is a setting where the new tab page displays the last ten sites I've visited - with all my pinned sites?

  There are two settings 'hidden' for this 'grid '.

  Browser.newtabpage.Columns
  
  and
  
  Browser.newtabpage.Rows

  Type of topic: config in the URL bar and press ENTER.
  
  So put . browser.newtabpage in the top search bar.

  Each of these preferences in the lower panel right-click and select Edit. Then change the value default of 3 for each of these preferences to what you prefer, for "pinned" both sites all browsing history you want to appear in the 'grid '.

• How can I limit the number libraries which is to find Photos

  How can I limit the number libraries which is to find pictures?

  I have about 10 libraries I've migrated opening today.

  I followed the advice I got from leonie, (level 10) below.

  Photos will create a new library of Photos in your iPhoto library.  The new library will be named as the iPhoto, with the extension ".photoslibrary" library and your original library will have a new file name extension ".migratedphotolibrary".  Rename the resulting ".photolibrary", so you will always be able to open in Aperture. The icons of libraries will change also. New photo library will display an icon of 'fan photos' with the flower of the Rainbow.

  
  

  So, I have now two files in my folder "Images".   One is called "Photo library" (these are ALL of .photoslibrary) the other is 'BACKUP ONLY iPhoto libraries' (these are ALL of .photolibrary).

  When I hold down the option key and start the Photos is to find all the libraries of two files above. How can I say Photos don't not to look in the old folder "iPhoto library"?

  This isn't a feature of Photos

  You can request that Apple itself - http://www.apple.com/feedback/photos.html - but not, it is not an option

• Is it possible to have the number of words together to always display?

  I use the statistics feature a lot of Pages and I think in a previous version, it was still visible. Now whenever I go to or create a different document that I have to manually switch to the view / display Word Count - go further down in the document, and then switch the display of 'character' to display 'words '.

  Is there a way to control this so the number of words on 'words' is the default view for any document I'm working with? Terminal command?

  Thank you!

  Rick

  You should always express what specific version of Pages with OS X that you are currently running. You can actually receive a community response more precise and punctual.

  There is no way to "sticky" user configurable to force Pages v5 on always display a number of words. It was a preferences: General option in Pages ' 09.

  Pages remembers a lot about your last use of it and stores this information in its list of preference file. When you choose the view menu: Show Word Count, the default is to show the characters in the bottom floating panel. This group contains each element with an integer value, that it stores in a variable update in the preferences file. When you change the characters, words, this value is updated and stored in the list of preference file. The next time that you are using Pages, he remembers this last variable parameter, and the floating panel shows words rather than characters. It is my experience test here.
