• When using the 'tools', 'Interactive objects', 'Add a button', how to make the text for the button name is displayed? I have tried everything and only the background, or lacxk, appears.

  I created a pdf document using Adobe Acrobat XI base and want to put a link on each page, return to the table of contents. However, the tool "Add a link" I cannot place this link on each page at a time. Accordingly, I used the tool 'Add a button' interactive Actions that allows me to do what I want. However, when I enter the name of the button, add background color (or not) and register, the name of the text for the button does not show, only the background appears (or nothing if I select no background). The button works, it just is not labeled. Any help will be appreciated.

  This is the area of the label, under Properties - Options.

• Acrobat 9 - Filliable text in the fields does not.

  We have to fill a form that we send to clients for donation requests. We recently received one that looked empty, so we had the customer fill it again. He came in a vacuum again even if the customer said they could see the text in the fields. I have opened the form to fill out and when I click in the field, he text appears but when I tab to the next field, it disappears and only shows the text in the current field. I looked everywhere but can't find an answer. It is as if it does not appear when you click in this field. Any thoughts?

• Adding new SCSI controller: "error string: invalid operation for the '0' device.»

  Hello

  I have a problem when I try to add a SCSI controller to a virtual machine.

  I have this error:

  Error string: invalid operation for the device '0'.

  Lack of details: InvalidDeviceOperation

  Here is my code:

  my $info = Description-> new (label = > summary of "" SCSI controller 2 ' = > 'LSI Logic parallel' ");

  my $controller = VirtualLsiLogicController-> new)

  deviceInfo = > $info,

  scsiCtlrUnitNumber = > '7'.

  sharedBus = > VirtualSCSISharing-> new ('noSharing'),

  busNumber = >-1,

  key = >-1,

  backup = > $backing_info,

  controllerKey = > 100,

  );

  My $devspec = VirtualDeviceConfigSpec-> new (operation = > VirtualDeviceConfigSpecOperation-> new ('add'),)

  device = > $controller,

  fileOperation = > VirtualDeviceConfigSpecFileOperation-> new ('create').

  );

  My $vmspec = VirtualMachineConfigSpec-> new (deviceChange = > [$devspec]);

  {eval

  $vm_view-> ReconfigVM (spec = > $vmspec);

  Util::trace (0, "Controller has been created. \n") ;

  };

  I don't know how to handle, or even how to solve problems.

  Any ideas would be greatly appreciated.

  Kind regards

  I finally found a solution.

  It seems that it fails if you give a marked as mandatory parameter (scsiCtlrUnitNumber, hotAddRemove)... Theses parameters seem to be set automatically, a dump of the device which will show.

  Here's the code used:

  My = $controller_spec

  VirtualDeviceConfigSpec-> new (device-online VirtualLsiLogicController-> new (key-online 0

  device-online [0],

  busNumber => $scsi_controller.

  sharedBus => VirtualSCSISharing-> new ('noSharing')),

  operation => VirtualDeviceConfigSpecOperation-> new ('Add'));

  My $vmspec = VirtualMachineConfigSpec-> new (deviceChange-online [$controller_spec]);

  {eval

  $vm_view-> ReconfigVM (spec-online $vmspec);

  };

  From my understanding a CLOB leave maximum string size of 2 GB.

  Not exactly:
  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/datatypes.htm#CHDDCGEE

  but this isn't the real problem.

  The error is about the "string literal" size, there is a limitation too:
  http://docs.Oracle.com/CD/E11882_01/server.112/e17766/pcmus.htm#sthref18132

  PLS-00172: string literal too long
      Cause: The string literal was longer than 32767 bytes.
      Action: Use a string literal of at most 32767 bytes.
  

  For the above, I fault the XML into several parts and run the PLSQL, then it gives no error.

  Is this a real case of production or you just test?
  In practice, we should first save the file in a variable/column CLOB (or XMLType) and then reference the content from there.

• REGEXP_REPLACE &gt; need to isolate only part of a string

  Hello world
  
  I hope someone can help me with this REGEXP_REPLACE building that I am on it for about 5 hours and I think I'm going crazy. :)
  
  So, I have a field in my DB that is populated by many lines like this:
  
  BREAKFAST 15: 00
  DINNER 30.00
  CITY TAX 1,50
  SPA 150.00
  
  
  It is an example.
  The field can be filled with this information, with lines, fewer lines, can be empty.
  
  What I have to do is to isolate only the price of the TOURIST tax. In this example, I need to get only the string "1.50'.» If the field is empty or if I don't have a line with tax, I need to go back to 0.
  
  My test is as follows:
  I made only one line and removed the spaces like this:
  
  Replace (replace (: RATE_PACKAGES, ' ', "), Chr (10),")
  
  Being the field of my DB RATE_PACKAGES that contain the information I need.
  
  With this replaces 2 I have: BREAKFAST15.00DINNER30.00CITYTAX1.50SPA150.00
  It's a bit ugly, but it seemed to me the best way to do it for me. :(
  
  And after that I did a single line without spaces, here's my REGEXP_REPLACE:
  
  regexp_replace (replace (replace (: RATE_PACKAGES, ' ', "), Chr (10),"), ' ([[: graph:]] *)([CITYTAX]) ([[: graph:]] {4})([[:graph:]]*)', '\3')
  
  I used [[: graph:]] * to exclude all printable characters from the string before tax then [[: graph:]] {4} to isolate the 4 characters (1.50) following the TOURIST tax and finally [[: graph:]] * yet to exclude all printable characters in the string that follows the price of the TOURIST tax.
  I'll be back only what I need with \3.
  
  This works perfectly if the TAX is the last line in the field = > ' 1.50'.»
  If there is something after, as in the example above, it returns = > 'PA15.
  
  I don't understand why. And there may be a simple way to proceed?
  
  I have tried several combinations in the REGEXP_REPLACE but I never get to get what I want. :(

• Omen of HP 15: Wifi stop working. Win10 shows only a single network and it connects to the WiFi

  Hi guys,.
  Since a few days my wifi stopped working.
  If I click the Wifi icon it shows only a SINGLE NETWORK (two maximum), but not mine!

  

  And I live in a building of 20 + networks, as you can see on the WiFi Analyzer (I'm the only red to the right)
  
  
  
  If I reactive / disable Wifi with fn + f12, it goes back in plane and Wifi mode mode and sees it eventually all networks:
  
  
  
  My Wifi is on top. If it is registered, Windows connects to it and then she abandons the connection; If it is not registered, and I try to connect, it says "you are not able to connect to this network.
  Is fun is that after a few seconds, each network disappears and alone is shown (probably the one next door... I don't know).
  
  I already tried to RESET the laptop MATERIAL by keeping the power button for 10-15 seconds with the laptop is turned off.
  I tried to follow these instructions (http://support.hp.com/us-en/document/c04649175) updated drivers (Intel 18.12.0.3, 18.12.1.2, 18.30.0.9 [10 default Windows], 18.32.0 [last drivers]) without success. Whenever I have install a new driver, I uninstalled the earlier software Wireless + restart.
  
  I tried to uncheked "allow this computer to turn off this device to save power" on my settings of Wifi hardware without success.
  
  HP network support said that I did not choose a Wifi (really? The problem is that I do not see my Wifi on the list!).

  This is unrelated to a new 10 Windows upgrade since I installed it months ago and this is the first time I have this problem :/ It has always worked
  
  I tried different settings too:
  I changed the channel, I put 802.11 g on my router, APSD off on the router.
  I put "Magic off packet, QoS ad hoc off, U-APSD off, fat wide channel, differential flow mode HT off" on the creation of the map without success. Nothing chaned.
  
  The hardware test detects any failure.
  
  Important note: If I close the router, it shows my network connection with full power and he connects to it. Then I come back in my room (probably 3/4 meters away), it MAINTAINS the connection for 30 / 40 min and he drops the connection and I cannot reconnect to it more. It has always worked perfectly in my room during these months (I bought it in March 2015), so the distance is not a problem, I'm 6 / 7 m away from the router.
  In this case, it shows my network (connected) and the nearby... and the other 20 networks +?
  
  The only way I have is USB tethering with my Nexus 5.
  
  Linux: I tried the WiFi on Freya elementary (Ubuntu linux OS base) and it displays 20 + networks available on the list. He has not the connection problem with my Wifi, but sometimes it stops working, Web pages stop loading and I have to restart Wifi to reconnect to the it (usually after 30/40 min of use it).
  
  -------------------------------------------------------------------------------------

  What is the problem? My Wifi card is broken? Should I call Italian support or if you have any suggestions?

  WAWood,
  I took a risk.
  I did a factory restore with recovery HP (I have a drive dedicated for her)... and it worked!
  I had to switch from Win8.1 to 10, but the Wifi problem is solved!
  
  I'm still guessing that was the problem...

  Now, I'm under Intel drivers 18.30.0.9 worm and all the networks work.
  
  In the next few days I'm checking the linux problem (reset deleted primary partition).

• Field validation text for the time format

  Hi all

  I have been breaking my head for almost 2 weeks, but am not able to figure it out... Please help me solve the riddle... here, it will:

  In a text field, I want to perform an operation in the following way:

  > a text default to 00:00:00 is defined at the moment as the text field is for the moment and the length in characters of the field is 8.

  > if the cursor is in position 0 (zero) and if I press a number of key it should replace the value of the 0 position and move the cursor to the next position.

  for example: 00:00:00

  20:00

  explanation : now the cursor is in position 0 and I press the 2 key it should replace the value 0 in position 0 and den move the cursor on the position 1 ie. next position...

  When I press a button not digital it shouldn't replace the value, but the slider should move to the next position.

  This seems to work ok. You need to test more, however. I've added a few properties for the hours, minutes and seconds as well.

• How you format the text in the fields for forms and buttons?

  I can't with that make up a form in InDesign for export in an interactive form in Acrobat. A couple of fields, the text is formatted as myriad as I want. On the rest, it is formatted to Minion and I can't seem to find anywhere to change this. I tried to do a "paragraph style" a character style, formatting a text box and nothing seems to work. Even tried to copy both entitled and their use for the other boxes, but it does not work. They returned to Minion.

  Any ideas?

  Don't know how you ended up with a different formatting, but in all cases, you can only control the choice/the font size in Acrobat, once your form exported in InDesign.
