• Calling shell script program SQL and passing parameters

  Hi guys,.
  Greetings from Toronto. Is it possible to move one or more strings as parameters to a sql from shell script program?
  
  Shell script

  # Accept system input parameters
  p_user_id=$1
  p_job_id=$2
   
  sqlplus.exe -s $p_user_id @$RD_PATH/rd_test.sql $p_user_id $p_job_id

  SQL program (rd_test.sql)
  

  -- Accept system input parameters
  define p_user_id = &1
  define p_job_id = &2
  
  -- Wondering if its possible to pass these 3 parameters from a shell script program.
  -- (1) rd_test-$p_job_id-3-1.lis
  -- (2) RD_PRINTER(rd_test,3)
  -- (3) t_data
  
  select
  t_data=''rd_test-'||'''$p_job_id'''||'-1-1.txt''
  t_data_dir=''.''
  ksh $RD_PATH/another_shell_prog.sh $p_user_id $p_job_id '||a.rd_value||' '
  ||b.rd_value||' rd_test-$p_job_id-3-1.lis $RD_PRINTER(rd_test,3) '||

  from rd_job_parameter b, rd_job_parameter a
  where a.job_id = &2
  and a.jp_module_id = 'RDTEST'
  and b.job_id = a.job_id
  and b.module_id = a.module_id
  /

  As always, this is not something I have to solve that minute. Any help would be appreciated
  and I will think of the problem.
  
  Thank you

  OK, just a few pointers possible if you need to go the way of shell script.

  I suggest that you have a separate SQL script for each of your options, which retains the fairly well-defined lines and keeps the maintenance as simple as possible. Therefore, in your shell script, you can have something like:

  #!/bin/ksh
  # Accept system input parameters
  p_user_id=$1
  p_job_id=$2
  
  # Deduce which script you'll call here
  # using if statements, or even a case:
  
  if [[ p_job_id -eq 1 ]]
  then
    SQL_SCRIPT=sql_script1.sql
  else
    SQL_SCRIPT=sql_script2.sql
  fi
  
  # Or using case
  
  case $2
    in
      1)     SQL_SCRIPT=sql_script1.sql;
  
      2)     SQL_SCRIPT=sql_script2.sql;
  
      3)     SQL_SCRIPT=sql_script3.sql;
  
      *)     SQL_SCRIPT=sql_script4.sql;
  esac
  
  export ${SQL_SCRIPT}
  
  #If you need to query the database at all to deduce which script to cal
  #Then something like this:
  
  SCRIPT_VAR=`sqlplus -s username/password << EOF
  set heading off
  set feedback off
  set verify off
  SELECT * FROM DUAL;
  EOF`
  
  export {SCRIPT_VAR}
  
  SQL_SCRIPT=sql_script${SCRIPT_VAR}.sql
  
  # Then just call your script:
  sqlplus. -s $p_user_id/password @${SQL_SCRIPT}
  

• Need help with a script (o - o8) *, see the Virgin if there is no

  Hi all what I need help with a script I can't find an example.

  I'm trying to subtract 2 numbers and then multiply this product. (o o8) * one but I just want to do the calculations if all fields have the numbers IE field o, o8 of field and field one.

  Thank you in advance. I was stuck on this days searching the Internet.

  Assuming you want to affect the outcome of this calculation in another text field, use this code as a custom field calculation script:

  var o = this.getField("o").valueAsString;
  var o8 = this.getField("o8").valueAsString;
  var a = this.getField("a").valueAsString;
  if (o!="" && o8!="" && a!="") event.value = (Number(o)-Number(o8))*Number(a);
  else event.value = "";

• Need help with custom script to rename the layers

  Hello world.

  I need help to write a custom script (because I suck at it) that will allow me to go through all the layers and sous-calques for a specific name ('X') and give it a new specific name ('Y').

  I have had success using the script below, but it does not work on any text layers names where the text layer was previously particularly well-known in 'X' and now changed needs.

  Any help is greatly appreciated.

  * Note: this script was originally used to find any layer with 'Copy' in its name and remove with anything after (to correct the problem of duplication of layers by adding this text).

  This is why the function is named removeCopy. It works for renaming layers also - just not a layer of text unfortunately.

  #target illustrator

  	function removeCopy() {}
  	If (app.documents.length == 0) return;
  	var app.activeDocument = docRef;
  	recurseLayers (docRef.layers);
  	}
  	removeCopy();
  	function recurseLayers (objArray) {}
  	for (var i = 0; i < objArray.length; i ++) {}
  	ObjArr [i] .name = ObjArr [i].name.replace (/ \s*current name\s*\d*/, 'new name');
  	If (objArray [i] .layers) recurseLayers (. layers.length > 0 ObjArr [i]);
  	}
  	}

  I finally found something after searching forums for a week. My confusion was related to the way Illustrator treats real layers against text/path/object "layers." Instead of layers, I had to use the pageItems in the script. The code below works. Thanks to Gustavo for his answer in another thread and Carlos I thank you for this looking too good! You're great to be ready to help models do more advanced things with Illustrator.

  	var doc = app.activeDocument;
  	var items = doc.pageItems;
  	for (var g = 0; g)
  	elements [g] .name = elements [g].name.replace ('Century Schoolbook text line', ' MonogramText: Century Schoolbook ");
  	};
  	App.Redraw ();

• Need help with windows scripting/media literacy

  It's kind of a strange question. I have a program at the same time a different video each month. every time that it runs, it checks to see which month it is and play the appropriate video. I have downloaded with the .mp4 extension videos and the program is just a batch file. I need the program to run whenever I start my computer, but after I connect. There should be a little late after that I connect to avoid crashing everything (my computer is a bit slow). I'm ready to use other programs. Help, please. BTW, I'm not quite sure which forum to post this in, let know me if I should change.

  Try this:

  1. Press +R to open the run.  Type : startup of the shell and click OK.
  2. Put here your batch file (or a shortcut)

  Now, when you connect, the batch file will run once the computer is recording in.

• Need help with a script customized for processing in Photoshop CS4 of images in batches. Really grateful for the help thereby.

  Hi people.

  So I have a boatload of pictures that I have to deal with as I'm moving off Ebay and open my own online store and the images that I have on Ebay, although excellent quality are not square, and unfortunately, the model that I use in Wordpress requires square photos.

  Basically, what I need is a script that I can use in batch mode, which will focus on the size of the image and change the canvas size to be square corresponding to the current long image side. Resize the image to 1600 square pixels and finally save for web in JPEG quality 60.

  Normally I would muddle my way through this trying to teach myself but I already do so much with this new project that I can't afford to pay developers for help that I would really appreciate if someone could help me with this script. I use Photoshop CS4 if it made a difference.

  Thanks much for any help you can offer.

  See you soon,.

  A simple gesture can do that. What you need to do is that the action of lot.   With the help of Photoshop Image Processor script.  The Action is a two-step

  N ° 1). File menu > automate > fit Image.  In the dialog box Image Fit you assign Width and Height 1600 pixels.

  Step 2.) Menu Image > canvas size.  In the canvas size dialog box, you assign Width and Height 1600 Pixels.

  Record the action in some action with a name like 1600PxSquare

  Then use the file menu to Photoshop > Scripts > image processor. In the dialog to the Image Processor script. Select your image source folder. Set where you want your jpeg images. Set it to save jpeg files quality 6.  Set it to include your 1600PxSquare action.

  Step adjustment image resize your image to fit in a 1600 x 1600 pixels are while keeping image proportions of images. Portrait image will be high 1600px and landscape image will be 1600px wide.  The step size canvas will add the canvas to make the place of the image.  Portraits will have a border on the left and right images of landscape will be confined to the op and downs.

• I need help to write script

  I was doing a form fillable Friday and I had someone to help him, but it does not quite work. I need a field to be is the difference between two fields, OR, if this difference is 0 or a negative number, it must be '0 '. The code we have written has worked to do simple subtraction, but he was always playing the negative number, AND more important still, it wouldn't "Refresh" I've changed numbers (I had 36-30, so it was show 6, but even when I started to clear the fields, he would remain at 6)

  Here is my domain names and needs:

  If exchangetotal-returntotal < = 0, then the value I show is 0 in the "sub-total" field (IE, you do not get a credit or refund if the value of the goods you are returning is greater than what you are in Exchange for)

  If exchangetotal-returntotal > 0, then the value is what is this difference. (IE, you will pay the difference if what you are sharing costs more expensive than what you have returned)

  (I had planned to paste the code that we had, but my stupid work computer won't let me paste half the time)

  In addition, this will of 'Custom calculation Script,' correct?

  
  Thanks in advance!

  ~ Heather

  You can use this script as "Subtotal" custom calculation script It will update automatically whenever you change a value of a field in your file (However, he won't like you, change only when you leave, because that's when the value actually takes effect):

  var v1 = +this.getField("exchangetotal").value;
  var v2 = +this.getField("returntotal").value;
  if (v1<=v2) event.value = 0;
  else event.value = (v1-v2);
  

• Need help please this script... LucD? :-)

  Everything works as expected, but I have a problem with the two parts of the script. They are the bits where he itterates the NETWORK card and hard drives (pink and blue sections below).

  Thanks for your help

  PS. I'm a complete NOOB with Powercli, so try to find my way around it yet.

  PPS - if someone has a better VM inventory script - please be so kind as to pointing me to it...
  

  Thought as well, but I'm afraid he wil cover the possibilities.

  Assume the following:

  VM1, 3 cards, 2 hard drives

  VM2, 2 cards, 5 hard drives

  The order will be VM1, VM2 with the effect that you get 2 hard drives for VM2.

  The alternative I came with us to make Dummy entries and always use the maximum columns for network cards and hard drives.

  If you want to get

  NIC1 NIC2, NIC3 HD1 HD2 HD3 HD4 HD5

  VM1 x x x x x na na na

  VM2 x x na x x x x x

  See if it works for you.

• Need help with a script of Fade Transitions

  I'm new to scripting so apologies if I've made a few obvious mistakes.

  In addition, do not know if there is already a feature in AE I don't know which will achieve

  what I'm trying to do, but I want to learn AdobeExtendScript and thought it was a great app for a script.

  I am trying to write a script allowing to adjusts video layers and opacity of the image key fades from 100% to 0% on a

  length of the frameworks determined by the user. Nothing too crazy. I've tested this script with imported parts of first and

  It works, kind of, but only when the first layer in the model is part of the selected layers.

  Here's the script:

  //

  fadeTransitions.jsx (03/12/12)

  Copyright © 2012 Paul Kelly for Perioperative Interactive education. All rights reserved.

  http:pkvisualization.com

  // http://pie.med.utoronto.ca

  //

  This script will be set a series of layers so that the layer opacity fades

  from 100% to 0% over a length of frames determined by the user.

  //

  var theComp = app.project.activeItem; the value of a variable equal to the active composition

  If (theComp == null |) (theComp instanceof CompItem) == false) / / check if the item is selected and make sure it is a CompItem

  {

  Alert ("you must have at least two selected layers");

  } else {}

  var numberOfLayers = theComp.selectedLayers.length; the value of a variable equal to the total number of selected layers

  If (numberOfLayers == null: numberOfLayers < 2) / / make sure there are at least two selected layers

  {

  Alert ("you must have at least two selected layers");

  } else {}

  var startLayer = prompt ("first layer to be affected:", "layer #");

  you want to remove this prompt and set a variable for the above selected layer.

  var startLayer = theComp.selectedLayers [0]; does not work. I want the lowest layer indexed multiple selected layers

  fadeTransitions();

  } //end second otherwise: numberOfLayers test

  } //end first thing: theComp test

  function fadeTransitions()

  {

  app.beginUndoGroup ("FadeTransitions");

  var overlap = parseInt (command prompt ("specifies the length of the fade-off (frames)", "0" "));

  overlap overlap = * theComp.frameDuration;

  for (var i = 1; i < = numberOfLayers; i ++)

  {

  var layerIndex = (startLayer - 1) + i; create the layer index, subtract 1 for compensation of the correct layer

  If (layerIndex > numberOfLayers) {//end before layerIndex becomes more than numberOfLayers

  Alert ("Transitions Fade script');

  break;

  } else {}

  var topLayerEnd = .outPoint theComp.layer (layerIndex);

  If ((layerIndex+1) > numberOfLayers) {//end before (layerIndex + 1) becomes more than numberOfLayers

  Alert ("Transitions Fade script');

  break;

  } else {}

  var btmLayerStart = theComp.layer(layerIndex+1).inPoint;

  var btmLayerEnd = theComp.layer(layerIndex+1).outPoint;

  term var = btmLayerEnd - btmLayerStart;

  theComp.layer(layerIndex+1).inPoint = (topLayerEnd - overlap);

  theComp.layer(layerIndex+1).outPoint = (topLayerEnd + duration);

  theComp.layer (layerIndex).opacity.setValueAtTime ((theComp.layer (layerIndex) .outPoint - overlap), 100);

  theComp.layer (layerIndex).opacity.setValueAtTime (theComp.layer (layerIndex) .outPoint, 0);

  } //end 2nd else

  } //end 1 else

  } //end for loop

  app.endUndoGroup ();

  } //end fadeTransitions function

  #1 problem: I want to eliminate the prompt asking the startLayer, instead, I want the first layer to be the highest of

  a selection of layers, so that at any time, you can select a series of layers and run the script only affect these layers.

  I tried to do this by setting a variable app.project.activeItem.selectedLayers [0]; but it did not work. This function would be really

  required during the later stages of compositing, when there are a lot of layers of subtitles, audio, 3D rendered images, etc. above

  layers of film in the model.

  #2 problem: unless the selected layers are pre-established way cascading, I get some really weird adjustments to the in-

  and outPoints. Not sure what is the cause. This isn't a priority, because most of the time I want to use this script layers

  will be already prepared properly (I import a Premiere Pro sequence), but still, I would like to know how I could solve this problem

  and to better understand how works ExtendScript.

  Problem #3: Right now, the way that these guys down inPoints are adjusted, is the same as if I flew over the inPoint layer with the mouse and

  got horizontally in line with the arrows of face to face and click-slipped the inPoint backward, but what I prefer is the

  equivalent of if I fly in the middle of the layer from the Selection tool and click-and - drag the entire layer L or R, so that it is inPoint

  is always in the same place in the sequence. As problem #2, it is not a great problem, I just want to better understand what is happening

  in the script. I tried to use startTime instead of inPoint in the script, but then it just stopped working completely.

  Any help/ideas would be greatly appreciated, and everyone feel free to use what I have so far if you wish.

  This give a try. I have not tested much, but I think it's pretty close to what you are after. It is not as limited to a selection of contiguous layers.

  This script will be set a series of layers so that the layer opacity fades

  from 100% to 0% over a length of frames determined by the user.

  "selectedLayers" is based on the order of selection, need a different approach to ensure that we are working from top down

  make an array of the indices of layer

  indexArray.push (theComp.selectedLayers [x] .index);
