  If time machine is incremental how it removes previous versions when the disk is full, without breaking the chain, so do not be able to restore the file with any changes made since the full backup first file...

  If the TM drive storage is full TM automatically deletes the version the oldest files for the new incremental backups can be made. Thus, in this case you cannot restore the versions that TM deleted because it takes more storage.

• How to remove line empty when the data are not for a text field

  I created a PDF with Acrobat Pro 11 model. This model has an address of the employer with the address line 1, address line 2, city, State, zip code, country. The requirement is to show address line 1 and line 2 address in separate lines and address line 2 cannot be present always. If address line 2 is not present then the PDF should not show a blank line. How do I get there?

  These data are populated through xml by a publisher of BI. New line characters do not work.

  Appreciate your help on this.

  Hi sprphoto123,

  If you do not enter data in the text field 2 then you can set the form field property to is not mandatory, but if you want to disable the 2nd text field, you can add a check box in front of it to turn off the field. This can be achieved using JavaScript.

  Kind regards

• How to stop Audio recording when no sound is detected

  Hello friends,

  I want to develop the application which is record audio (implementation of this part, I already had)... but I want to stop recording when device has been not detect any noise over 2 sec audio...

  I already convert the data byte in data short tosigned that is giving me the length of the sound...

  int level = (signedShortToInt (b) * 100 / 32767); b is the data buffer

  mutable public static int signedShortToInt (byte [] b) {}
  result int = (b [0] & 0xff). (b [1] & 0xff)<>
  return the result;
  }

  I'm familiar with the sound of noise of air is in normal recording...

  Air noise level not more than 100 (im guessing).

  so I had checked the voice level is below 100 it will stop recording...

  My idea is correct or not?

  private void jesuissuper (byte [] buffer) {}
   
  for (int i = 0; i)< buffer.length;="" i++)="">
  Byte [] b = new byte [] {[i] buffer, buffer [i + 1]};
  int level = (signedShortToInt (b) * 100 / 32767);
  If (100 > level) {}
  Voice.StopThread ();
  }
  }
  }

  My Question is... How can I stop the recording when the level is low up to 2 sec and it is the Correctmethod to find the sound level?

  Hello guys,.

  I have not found any Solution for this so I drop this idea...

  I had found my solution up to convert PCM ampltude data... Using the Amplitude level I can is find the noise data and hat is given voice. and stop Audio in usin it

  But not audio recorded in the camera store...

  Thank you...

• How to remove a step with the polygon Lasso tool

  How to remove a step with the polygon Lasso tool

  In PS, all you have to do is to hit the DELETE key and you can go back a little with the polygon Lasso tool. How to accomplish this in Fireworks?

  Another option that gives you a lot of control is to use the tool pen instead of the polygon lasso. Because it's a vector path, you can refine the outline very easily using the tools of feather and Subselects and when you are satisfied with the result, click on modify > convert a path to the top. You can even choose to keep or delete the vector path in the preferences panel.

• How to remove a Word from the default dictionary of firefox?

  How to remove a Word from the default dictionary of firefox?
  If I wanted to remove the word 'dog' or 'and' for example

  There may be a range of reasons for wanting to do this, including the deletion of the words you use rarely as similar to other common spellings used words for example. "minute" and "Minuet", delete the words that you find personally offensive, or removing words that, because of linguistic or cultural background, you would not consider words at all.

  Note that I'm not asking how to remove my 'dictionary' words, words that I added myself.

  Hello

  I talked to a few people and I think I'm able to help you with this.

  There are two dictionary files, the default that comes with your version of Firefox and personal 'custom' that you create yourself with phrases and words.

  If you want to change the personal;

  1. Copy Subject: support and paste into the address bar.
  2. Next to the profile folder, click the marked File Show
  3. Find the file persdict.dat. Rename a text file, open, modify, re save it as persdict.dat and replace.

  If you want to change the default dictionary, it could be more of a problem and a lot more technique to do. I would recommend that you look at the problem differently and consider filtering of pages based on inappropriate content using Add-ons such as ProCon Latte Content Filter.

  I hope this helps, but if not, please come back here and we can look at another solution for you.

• case structure: to run once when the condition is true

  I have a case structure in my program. I use this to count the number of cycles in my experience. I have a knot of feedback (image of the program here attaced) within a box structure. I want the case structure to run only ONCE when the condition is "TRUE". Each "TRUE" represents each cycle. The problem that I'm facing here is that the box structure is permanently running as long as it is 'TRUE' instead of running once and wait for the next 'TRUE '.

  Temporaritly I use a timer inside (as you can see in the picture) to contain the program for the next 'REAL' to come. I hold as by case so I know exactly the time. Is it possible to make the case structure running only once when the condition become ' TRUE and wait for the next "REAL"?  OR is there any other loop that case structure that make this work?

  Hi aneps,

  PtByPt_BooleanCrossing is your friend!

  You really need to work on the analysis/description of your problem: you don't want to run the case as long as the entry is set to TRUE, but you want to run the case at the entrance of the past from FALSE to TRUE!

• How to remove a shortcut with the command line?

  How to remove a shortcut with the command line?

  How to make a backup of the local users and groups with command line?

  You delete a shortcut, just as you would remove any other file.  A shortcut will end with the extension ".lnk".  So assuming you are trying to remove the shortcut named "Shortcut.lnk" which appears to the user 'Bob's Office, you use the button Delete (del) or 'clear' command by specifying the full path to the file.  (Remember to put filename in quotes if there is a space anywhere in the path or name) as in:

  del "C:\documents and settings\Bob\Desktop\Shortcut.lnk".

  What kind of a backup 'users and groups' you want to do?  If there is a backup of the users and groups as written in the registry, a good registry as C:\WINDOWS\ERUNT backup program that will make the command line.  If you are trying to backup all users and their data as well, then you are better off with a backup program.

  Hi Piya,

  I run your code, and according to your logic that it works correctly.

  It's adding that line only once because according to your logic that one line can be added to MDT, if you do not want to add line on each click on the button, follow these steps:

  selectedindex1 = chart [obj1.getSelectedIndex ()];
  selectedindex2 = shade [obj2.getSelectedIndex ()];
  selectedindex3 = rolls [obj3.getSelectedIndex ()];
  selectedindex4 = cuts [obj4.getSelectedIndex ()];

  Lbl1 LabelField = new LabelField("");
  Lbl2 LabelField = new LabelField("");
  LabelField lbl3 = new LabelField("");
  LabelField lbl4 = new LabelField("");
  If (LBL1. GetText(). Equals("") | LBL2. GetText(). Equals("") | lbl3. GetText(). Equals("") | lbl4. GetText(). Equals(""))
  {
  LBL1. SetText (selectedindex1);
  LBL2. SetText (selectedindex2);
  lbl3. SetText (selectedindex3);
  lbl4. SetText (selectedindex4);
                  
  GFM. Add (LBL1);
  GFM. Add (LBL2);

  GFM. Add (lbl4);

  How to remove all information from the computer so I can sell it?

  Hello

  You will want to format the hard disk:

  1. you can use DBAN - http://www.dban.org/

  or

  2. you can follow this tutorial to clean install up to the step where you format the disk, in which you would then STOP (because you just want to get rid of the files on the hard drive, do not install Windows) - http://www.sevenforums.com/tutorials/1649-clean-install-windows-7-a.html
