I have a list of items, and each item have a list of instructions. Each item will be printed out into a PDF file with each instruction occupying one page and saved locally. What i have now is a for loop which queries the database for the instructions of each item, and after populating the PDF pipe it out to a path. The problem is due to the query being async, only the last PDF being piped can be opened, the rest are corrupted. How do i overcome this? My code is as shown below.
var counter = 0
for (var o=0; o<itemList.length; ++o){
Steps.find( {itemid:itemid[o], sort: "sequence asc"} ).exec( function(err,steps){
doc[counter] = new PDFDocument();
if(!err){
doc[counter].pipe( fs.createWriteStream(path + "DocName" + counter + ".pdf") );
for (var x=0; x<steps.length; ++x){
doc[counter].text("Instructions: " + steps[x].instruction.font('Times-Roman', 13);
}
***/*if (counter == itemList.length-1){
doc[counter].end();
}*/***
//That is the problem, i shouldn't have done the check and end the doc immediately, that solved the issue.
doc[counter].end();
++counter;
}
}
}
Edited the question to show the working solution. A careless mistake where i only do a doc.end() after the last file is written, instead of ending it after every single file.

its for a unity research project, I dont want to have to press control v exactly 400 times. I just want to paste it in another .txt file
this is the text
http://pastebin.com/m1u4AFAr
Thank you for you help
Use Unity. Go to that link and copy the text. Run this script in Unity and it will duplicate the text for 400 times and save it. It will show you where it saved it. Any text you have in the clipboard will be duplicated 400 times.
void Start()
{
//Get Clipboard
string fileInfo = GUIUtility.systemCopyBuffer;
if (fileInfo == null)
{
Debug.Log("Clipboard is Empty. Exited");
return; //exit
}
//Multiply by file 400
System.Text.StringBuilder crazyfileX400 = new System.Text.StringBuilder();
for (int i = 0; i < 400; i++)
{
crazyfileX400.Append(fileInfo).Append("\r\n");
}
string filename = Application.persistentDataPath + "/" + "crazyFile.txt";
System.IO.File.WriteAllText(filename, crazyfileX400.ToString());
Debug.Log("File written to " + filename);
}
Have a look at this open source macro-creation and automation software.
You can use it to write a script that does the job for you. Here's a a script for simple copy and paste:
#c::
Send, {CTRLDOWN}c{CTRLUP}{ALTDOWN}{TAB}{ALTUP}
sleep, 300
Send, {CTRLDOWN}v{CTRLUP}{ENTER}{ALTDOWN}{TAB}{ALTUP}
return
You could adapt it to your situation by adding a loop.
I have a Google Apps script which replaces placeholders in a copy of a template document with some text by calling body.replaceText('TextA', 'TextB');.
Now I want to extend it to contain images. Does anybody have idea how to do this?
Thank you,
Andrey
EDIT: Just to make it clear what my script does. I have a Google form created in a spreadsheet. I've created a script which runs upon form submission, traverses a sheet corresponding to the form, find unprocessed rows, takes values from corresponding cells and put them into a copy of a Google document.
Some fields in the Google form are multi-line text fields, that's where '\r\r' comes from.
Here's a workaround I've come up with by now, not elegant, but it works so far:
// replace <IMG src="URL"> with the image fetched from URL
function processIMG_(Doc) {
var totalElements = Doc.getNumChildren();
for( var j = 0; j < totalElements; ++j ) {
var element = Doc.getChild(j);
var type = element.getType();
if (type =='PARAGRAPH'){
var par_text = element.getText();
var start = par_text.search(new RegExp('<IMG'));
var end = par_text.search(new RegExp('>'));
if (start==-1)
continue;
// Retrieve an image from the web.
var url = getURL_(par_text.substring(start,end));
if(url==null)
continue;
// Before image
var substr = par_text.substring(0,start);
var new_par = Doc.insertParagraph(++j, substr);
// Insert image
var resp = UrlFetchApp.fetch(url);
new_par.appendInlineImage(resp.getBlob());
// After image
var substr = par_text.substring(end+1);
Doc.insertParagraph(++j, substr);
element.removeFromParent();
j -= 2; // one - for latter increment; another one - for increment in for-loop
totalElements = Doc.getNumChildren();
}
}
}
Here is a piece of code that does (roughly) what you want.
(there are probably other ways to do that and it surely needs some enhancements but the general idea is there)
I have chosen to use '###" in the doc to mark the place where the image will be inserted, the image must be in your google drive (or more accurately in 'some' google drive ).
The code below uses a document I shared and an image I shared too so you can try it.
here is the link to the doc, don't forget to remove the image and to put a ### somewhere before testing (if ever someone has run the code before you ;-)
function analyze() { // just a name, I used it to analyse docs
var Doc = DocumentApp.openById('1INkRIviwdjMC-PVT9io5LpiiLW8VwwIfgbq2E4xvKEo');
var image = DocsList.getFileById('0B3qSFd3iikE3cF8tSTI4bWxFMGM')
var totalElements = Doc.getNumChildren();
var el=[]
for( var j = 0; j < totalElements; ++j ) {
var element = Doc.getChild(j);
var type = element.getType();
Logger.log(j+" : "+type);// to see doc's content
if (type =='PARAGRAPH'){
el[j]=element.getText()
if(el[j]=='###'){element.removeFromParent();// remove the ###
Doc.insertImage(j, image);// 'image' is the image file as blob
}
}
}
}
EDIT : for this script to work the ### string MUST be alone in its paragraph, no other character before nor after... remember that each time one forces a new line with ENTER the Document creates a new paragraph.
I have a very simple ExtendScript script which creates a new document out of a subset of the current active document:
var sourceDocument = app.activeDocument;
var i, j;
for(i = 0; i < sourceDocument.layers.length; i++) {
sourceDocument.layers.item(i).locked = false;
}
for(i = 0; i < sourceDocument.spreads.length; i++) {
for(j = 0; j < sourceDocument.spreads.item(i).textFrames.length; j++) {
if(sourceDocument.spreads.item(i).textFrames.item(j).locked) {
sourceDocument.spreads.item(i).textFrames.item(j).locked = false;
}
}
}
var destDocument = app.documents.add();
var firstPageIndex = 0; // In the actual script, this is chosen by the user.
var lastPageIndex = 5; // In the actual script, this is chosen by the user.
destDocument.importStyles(ImportFormat.paragraphStylesFormat, new File(sourceDocument.filePath + "/" + sourceDocument.name), GlobalClashResolutionStrategy.LOAD_ALL_WITH_OVERWRITE);
destDocument.importStyles(ImportFormat.characterStylesFormat, new File(sourceDocument.filePath + "/" + sourceDocument.name), GlobalClashResolutionStrategy.LOAD_ALL_WITH_OVERWRITE);
destDocument.viewPreferences.horizontalMeasurementUnits = sourceDocument.viewPreferences.horizontalMeasurementUnits;
destDocument.viewPreferences.verticalMeasurementUnits = sourceDocument.viewPreferences.verticalMeasurementUnits;
destDocument.documentPreferences.facingPages = sourceDocument.documentPreferences.facingPages;
destDocument.documentPreferences.pageHeight = sourceDocument.documentPreferences.pageHeight;
destDocument.documentPreferences.pageWidth = sourceDocument.documentPreferences.pageWidth;
destDocument.documentPreferences.pageSize = sourceDocument.documentPreferences.pageSize;
destDocument.documentPreferences.allowPageShuffle = true;
var range = sourceDocument.pages.itemByRange(firstPageIndex, lastPageIndex);
range.duplicate(LocationOptions.AFTER, destDocument.pages[destDocument.pages.length - 1]);
destDocument.pages[0].remove(); // An empty spread containing an empty page is added when the new document is created and we cannot remove it before other pages are inserted (Documents must have at least one page)
This script works perfectly on many documents. But when I execute it against one particular document (let's call it foo.indd), InDesign becomes unresponsive when executing the duplication: range.duplicate(LocationOptions.AFTER, destDocument.pages[destDocument.pages.length - 1]);. From then on, the only thing I can do is force InDesign to quit.
Is this an InDesign bug? How can I find which part of this particular document is creating the problem?
I can't really say what's wrong in your example but if indesign hangs, that might caused by the loops ( to infinity and beyond :) )
So you may try to avoid issues by outputting the loop limit to avoid InDesign re-calculation
var limit = …
for ( i = 0; i<limit ; i++)…
Additionally you could try to write info on the console to get info where InDesign is actually being stuck. So write informations on the fly on a report file and you might finally identify the issue area.
Also, you can try to interrogate every key items to see if the file has some issue.
Last but not least, try a manual export to idml of this file, re open and run again the script. Sometimes files become clunky and passing by idml fix most of them.
Give this script a try onto your probleamtic file. If it fails, please have a look at the report it should have generated onto the desktop.

my code :
object c = "d:\\1.doc";
if(File.Exists(c.ToString()))
{
File.Delete(c.ToString());
}
error :
The process cannot access the file 'd:\1.doc' because it is being used
by another process.
How close ? with code
first of all use string instead of object, so:
string c = "d:\\1.doc";
now as the message indicated the file being used by another process. either by windows process, or you are opening the file stream and forget to close it. check in your code where you are interacting with the file.
Edit: Since you are using Microsoft.Office.Interop.Word make sure you close the file(s) open first like:
Word.ApplicationClass word = new Word.ApplicationClass();
//after using it:
if (word.Documents.Count > 0)
{
word.Documents.Close(...);
}
((Word._Application)word.Application).Quit(..);
word.Quit(..);
I had the same type of issue when I wanted to Delete File after Open/Read it using Microsoft.Office.Interop.Word and I needed to close my document and the application like that :
private void parseFile(string filePath)
{
// Open a doc file.
Microsoft.Office.Interop.Word.Application application = new Microsoft.Office.Interop.Word.Application();
Document document = application.Documents.Open(filePath);
// Loop through all words in the document.
int count = document.Words.Count;
for (int i = 1; i <= count; i++)
{
// Write the word.
string text = document.Words[i].Text;
Console.WriteLine("Word {0} = {1}", i, text);
}
// Close document correctly
((_Document)document).Close();
((_Application)application).Quit();
}
You have that file actively open in this or another program, and Windows prevents you from deleting it in that case.
Check if the file still running (opened) by another application
1- Microsoft Word
2- WordPad
I save a node with images which is beeing filled by a service. I write the image with drupal_write_record and the pictures appear in the node already. But when - at the end of the script - I call a node_save the image disappears again.
My Code:
$file_drupal_path= $filedata['location'];
$file = new stdClass();
$file->filename = $filedata['name'];
$file->filepath = $file_drupal_path;
$file->filemime = $filedata['mime'];
$file->filesize = filesize($file_drupal_path);
$file->filesource = $filedata['name'];
$file->uid = 1;
$file->status = FILE_STATUS_PERMANENT;
$file->timestamp = time();
$file->list = 1;
// fid is populated by drupal_write_record
drupal_write_record('files', $file);
$imageData = field_file_load($file->fid, TRUE);
return $imageData;
and the node_save
function transport_service_save($node) {
$node = (object) ($node);
$node->promote = 1;
node_save(node_submit($node));
return print_r( $node , TRUE );
}
in the cck image field in the node there are keys with unset values as well.
Andreas,
Had the exact same problem.
Using drupal_execute() as described here fixed the problem immediately:
// Save the node, updated or new
// Get the node object as an array the node_form can use
$values = (array)$node;
// Save the node (this is like pushing the submit button on the node edit form)
drupal_execute('abc_node_form', $values, $node);
Source:
http://www.drupalisms.com/gregory-go/blog/use-drupalexecute-instead-of-nodesave-to-save-a-node-programmatically
But a fair warning: it ran like a charm for the first few rounds, but now I get tonnes of errors type:
warning: call_user_func_array() [function.call-user-func-array]:
First argument is expected to be a valid callback, 'node_form' was given in ...
Can't see what changed. All I did was call the page that did the saving a few times to test it.
And a final (hopefully!) edit to this reply. It seems that including the node.module file that contains node_form is needed, so adding this:
module_load_include('', 'node', 'node.pages.inc');
in your code (like in hook_init()) will do the trick.
Worked here, and now my nodes save with images intact.
