• Phones unlocking password box smart blackBerry. Keyboard allows only numeric characters.

  I choose aA which is at the top right, but this disappears 123 boxes and in the top right of the screen is displayed when you try to unlock the keyboard.  The 123 box does not turn off when the unlocking password box is displayed. Alphabetic characters in my password may not be seized at all from the table, only those digital.

  I can't unlock and therefore to use the phone.

  I removed the battery and restarted a couple of times without change.

  Ideas welcome!

  The problem is only with the normal box saying "Enter PIN Code".

  There is your idea, he wants the PIN SIM lock code, it does NOT have a password, I promise you.

  If you do not know your PIN, call O2 and ask. It's NOT the same as a smart phone BlackBerry PIN (which is eight alphanumeric characters. He wants a digital code to four digits.

• I'd do the signature field read only until something is entered in the required fields.

  I'd do the signature field read only until something is entered in the required fields.

  Attached a sample file that has two text fields and field of signature, the signature field allows only when certain values are typed in two text fields.

  Steps to achieve this:

  (1) disable the signature field when the form is loaded

  (2) to activate when the two text fields values are not null

• Regular experssion Unicode: allowed only numbers and letters

  What is the best way to write the query that generates the data according to the rules:
  (1) input string may include only numbers or letters, other symbols are not allowed,
  (2) numbers must be positive integers together: 0. 9 paper, no point or a comma or a space allowed in numbers.
  (3) letters may be lower or uppercase, regardless.
  (4) letters/characters may come from an English alphabet and can come from an Estonian alphabet, see BOF MCet alphabet letters he
  http://en.Wikipedia.org/wiki/Estonian_alphabet
  Thus, the symbol of the alphabet "Has two chief points" must also be accepted. Would be preferable that the German alphabet is allowed too and any alphabet is allowed, if possible.

• InDesign Page allowed only eight characters article?

  In the page of my document with the prefix to more than eight characters. How to handle this scenario?

  example of number of myPage = 475, 1-23, 1-75

  Pagno = 1

  prefix: 475, 1-23, 1-75, 1

  Please advice. Adobe needs to fix this.

  This is the limit. Yes. You can't do anything.
  Other than to request a feature and hope for the best.

  Work-around would be possible.
  Change the content of the page on every page of script name according to your rules.
  But it is not flexible.

• Check that only one box to advance to the text field

  I work in Acrobat Pro ms, I created a form and I have the following problem. The application form concerning the rental income, either monthly or annual (the format is less).

  What I want to happen, is if possible, if the user clicks on the checkbox monthly (monthly) the cursor goes to the 2 text and the user has entered the monthly amount.

  If the user clicks on the annual check (per year), the cursor goes to Text1, the user enters the annual amount. This amount is automatically divided by 12 and shows in the Text2 text field; and the cursor goes in the following text, Text3 field.

  Naturally, I don't want the user to click on the two boxes, but I don't know that the coding would take care of that, just do not know how come with the coding.

  £ Rental income monthly

  £ Annual if, Yes $ Text1 / Text2 $12

  Thanks for the help.

  You have 3 separate issues here:

  -Exclusive box

  -Jump to another field

  -Calculate the monthly payment

  -Exclusive box: you must give the two fields of the same name (say "times"), but the different export value, say "Monthly" and "annual".

  -Jump to another field: As the MouseUp event of the 'Monthly' box enter this script:

  this.getField("Text2").setFocus();
  

  As the event MouseUp "Annual" box enter this script:

  this.getField("Text1").setFocus();
  

  etc.

  -Calculation of the monthly payment: so you want this value to be entered by the user if the "Monthly" option is enabled, but being calculated if the "Annual" option is selected? It's a little complicated to implement in a single field, but you can try to use something like this as the "Text1": custom validation script

  if (event.value && this.getField("RentalPeriod").value=="Yearly")
       this.getField("Text2").value = Number(event.value)/12;
  

• Use matching of regular expressions to search for parentheses

  Hi all

  I am currently looking for a particular pattern in a string, I can't display the exact string, but say its something like that.        corresponds to regular_pattern (5000): 0

  I'm also looking for the a different model at the same time, so I have to use the corresponding regular expression and the | function.  I can't understand how to match this model because the regular expression function allows parentheses unless I put them in the legs, and that does not help me for this.

  Any advice?

  Thank you

  Matt

  Have you tried to escape the bracket?

  

• Regular expression matching is not what matches Pattern

  I read a lot of posts on how match model does not match what match regular expressions will be due some characters does not.

  However, I found a problem with the other way. A simple Reg - Ex who works in the match pattern but not regular Expression match.

  What I have here is just an example. I want to use regular Expression Match then I can specify some matches under.

  The reg - ex's: one or more non-numeric characters, a space, one or more numeric characters. At the beginning of the string.

  How can I get this to work in regular expression matching? I work in LabVIEW 2010f2 32 bit. Here is the code snippet and the results:

  

  Rob

  One of the subtle differences is the operator of negation for the character classes.  In match pattern is ~, but for the Match RegEx is ^.

• AFExactMatch and regular Expressions

  Hello

  I'm working on something similar to this http://forums.adobe.com/message/4215772#4215772.

  My first shot at it.  Found it useful messages of try67 and George.  I'm almost there and now, I'm stumped.

  My Custom Format Script is the following:

  Custom Format script for the text field

  If (event.value) event.value += '% ';

  My typing a custom Script is the following:

  Custom keystroke script

  DigOnlyKS();

  My custom calculation script is the following:

  If (event.value == "") event.value = 0;

  My Javascript Document is:

  function DigOnlyKS() {}

  Get everything that is currently in the field

  var val = AFMergeChange (event);

  Refuse entry if other thing that the figures

  Event.RC = AFExactMatch (/ \d* /, val);

  Event.RC = AFExactMatch (/^100\.0| [1-9] {1,2}\.\d{1}|0\.\d{1}$/, val);

  }

  Valid entries must be: 100.0, 1.0 to 99.9, and 0.1 to 0.9.

  The regular Expression seems to work on the Regex testers online.

  However, I can't enter anything in the field with the foregoing.

  If replace my Regex with the link above - ^ \d+\. ? \d{0,2}$ - I can enter data in the field.

  However, if I remove the? the - ^\d+\.\d{0,2}$ - regex to require (I think) the decimal places, I can't enter anything in the field.

  Clearly, Miss something.

  Thank you.

  Regular expression is not appropriate for a typo script until the value has been committed, and even in this case, it may be too restrictive (for example, does not allow for ".") 9 »).

  The way I would be inclined to implement would be to put the strike and Validate Format (not calculate) scripts to call the following functions, respectively.

  // Custom Keystroke script calls this
  function percent_ks() {
  
      AFNumber_Keystroke(1, 1, 0, 0, "", false);
  
  }
  
  // Custom Format script call this
  function percent_fmt() {
  
      AFNumber_Format(1, 1, 0, 0, "", false);
      if (event.value) event.value += "%";
  
  }
  
  // Custom Validate script calls this
  function percent_val() {
  
      if (event.value === "") event.value = 0;
  
      // Only allow numbers from 0 to 100
      if (+event.value >= 0 && +event.value <= 100) {
          // round to nearest tenth
          event.value = util.printf("%.1f", event.value);
      } else {
          event.rc = false;
          app.alert("Your error message goes here.", 3);
      }
  
  }
  

  It lets you enter values outside the valid range, but the validation script takes care of it. It also allows more than one digit to the right of the decimal, but the validation script it rounds up to the tenth closest. Make sense?

• Regular expression to remove a single carriage return character

  Hi all
  
  What is the regular expression to remove only one character to return to a text string. I have something like this:
  
  1
  
  (two returns)
  
  2
  
  and I want to delete only one of the characters turn it over so I'll go
  
  1
  2 (one after the other
  
  I know / r but ot deletes all of the text string.
  
  Thanks a lot for any help
  

  Try something like:
  (in my message window):
  s = "a" & RETURN & RETURN & "two".
  placed s
  l = [s]
  put re_replace (l, "(?)")<=\r)\r", "g",="">
  Place the [1]
  (exit):
  -"a".

  two ".
  -1
  -"a".
  two ".

  I don't know how effective the situation described above could be for research, but
  You can also try:
  put re_replace (l, "\r\r", "g", RETURN)
  or:
  put re_replace (l, "\r{2"}, "g", RETURN)
  However, these last 2 only work in the situation where there
  exactly 2 returns you want to replace with a single DECLARATION - the first
  replaces any number of multiple returns with one RETURN

  It is possibly more effective than the first - it will replace again
  all multiple with a single; but it will unnecessarily replace one
  RETURN character with one character in RETURN - but I'm not a regular expression
  Expert:
  put re_replace (l, "\r+", "g", RETURN)

• Complex regular expressions without multiple passes

  Does anyone know of a tool that can handle more complex regular expressions without chaining of multiple copies of the VI regular expressions?

  For example, if I have a XML string as

  Power supply error has occurred.

  Sorensen SGA166/188

  and I am interested in the tag method to retry only, I could write a regular expression something like

  .*.*

  to parse the string inside the tag.

  kc64 wrote:

  For example, if I have a string like

  My email address is [email protected].  Please no spamming not me.

  and I am interested in the domain name of the email only address, I could write a regular expression something like

  @(\w)*\. (com: net | org)

  to parse the string 'gmail '.

  Forgive me if I am away from base, but I'm flying blind at the moment (not LV to test what I say).  You can add to the power of a regular expression using submatches or capture groups.  The regular expression you wrote will grab (I think) @gmail.com for the entire game.  Let's say you want to get 'gmail' without a second function call.  You can do the first group of a little dishonest selection by moving the * inside the parentheses.  Then, on the BD pull down on the bottom of the function of regular expression matching to expose a variable number of submatches (both should be in this case).  The first should be 'gmail '.   The second one should be "com."

  In summary, @(\w*)\.) (com: net | org) should give you gmail in the first submatch.  Of course, my Perl is a little rusty and LV cannot apply in the same way.

• Search for a string using "Game Plan" or "Regular Expression to Match."

  Hello

  I would use the 'game plan' or the vi "Expression regular game" simply because the products that provide these vi. The result that interests me is the substring 'after '. I want to be able to specify a "substring" and get everything after the substring of the input string. However, I'm getting all confused and/or watered upward when it comes to "regular expressions". Is there a way to create a "regular expression" which acts as a 'substring' to find within the input string?

  The substring is a path of partial directory that contains a colon, backslashes, etc. which are part of a directory path.  If some how the "regular expression" entry must ingnore all special characters and simply to understand if the substring in the string entry and give me 'all things' after the substring in the output of 'after the string.

  Use Regular Expression Match instead of match pattern; It's better.
