• vCO and reading/writing files

  Hello community,

  I am a newbie with vCO, sorry for the basic question perhaps.

  I created a "workflow" for automatic deployment and customization of VMs. job well enough, the model is cloned, sysprep, vCPUs and RAM set and so one. But the final customization tasks is to assign a unique IP address that is in a list in a plain text file. vCO should open the file, take the first IP address in the first line, remove it and close the file (DHCP is not an option). I can open and read the file with the options of '.readall' and a 'player', but which is not exactly what I want. I tried a few '.readline' which translates as "cannot find function readline" and after I I thought to split the entire string that resulted in "no defined split." I really don't know if this is the right way.

  Can someone please guide me in the right direction, perhaps with a few code snippets?

  Thank you very much!

  S.

  OK, here's another example, which reads the entire file into a string, and then use split() for areas exploded in the elements of an array:

  var fr = new FileReader("C://vcoscripts/demo.txt");
  fr.open();
  
  var complete = fr.readAll();
  System.debug("complete: " + complete);
  var lines = new Array();
  lines= complete.split(/\r\n|\r|\n/);
  System.debug("lines: " + lines);
  for (var linenr in lines) {
      var currentLine = lines[linenr];
      System.debug("currentLine: " + currentLine);
      }
  

  With this, you can use methods of standard table (push(), pop()), which might be easier to use.

  The regular expression to split the lines that I got:

  http://StackOverflow.com/questions/1155678/JavaScript-string-newline-character

  (good reading...)

  Edit: I forgot: with Array.strip (), you can remove an element of a table (in your case the IP address used before writing it back to deposit via FileWriter...)

  Hey derizz,

  Welcome to the Microsoft Answers site.

  If you cannot copy files normally, try to copy guest rather using Xcopy command.

  1. click on start, principally made programs, click Accessories and then right-click on command prompt, click Run as administrator.
  2. type the following command line and press ENTER. In the command line, drive is the letter of the CD drive or DVD drive.

  xcopy drive:-*. * /s > c:\test1

  See if that helps to successfully copied the files on your hard drive.
  Kind regards

• reading / writing file of computer network

  HelloW!

  I have to read pc specific network, save/display the path file and then write back the file I've already read, and then after confirmation that the file written is correct I have proceed please guide me steps in order to achieve this... Although this is a very basic question, but I ask you to start as I've never used before network with cvi. Please provide us with some examples of code if possible

  Thanks in advance

  A lot depends on how you get the path to the original remote file.

  If the process starts with the operator interactively by selecting the file (for example with FileSelectPopupEx), you can simply use the path returned by the function and process the remote file somehow on your PC.

• How to read/write files in Photoshop CC?

  Hi all
  I have plugin for Photoshop CC2014 and above using node.js to reading/writing files, download remote files and restful calls. It does not in Photoshop CC because CC uses 4 CSXS and node.js is not available here. So is it possible in javascript to perform these operations (reading/writing/download) in CSXS4? I think I can use XMLHttpRequest to download files, but how to read and write? Thank you!

• How can I specify the options of folders and files to memory cards in LR4?

  Hello!

  I read the sections Set import and file management preferences and settings to specify Auto Import in the manual. But they do not seem to answer my question. Other things that are written about importing files in Lightroom seem to relate only to importing photos to the Lightroom Catalog, that is not my main concern, although I do not want them imported into the catalog as well. But before the pictures can go to the Lightroom Catalog, they need to be improted, in other words copied from the memory card on the local hard drive. In short, all I want is for Lightroom to take over the responsibility of Canon EOS Utility and behave in the same way during the import/copy of the files on the local hard drive. How is Lightroom sets for this?

  I want to just this type of file and folder structure:

  J:\2010_08_02\IMG_0037.JPG

  J:\2010_08_02\IMG_0039.JPG

  J:\2010_08_22\IMG_0372.CR2

  J:\2010_08_22\IMG_0372.JPG

  J:\2010_11_29\IMG_1405.CR2

  J:\2010_11_29\IMG_1405.JPG

  J:\2011_06_17\IMG_2887.CR2

  J:\2011_06_17\IMG_2887.JPG

  ... etc!

  1. let's all start, where the heck can I specify the destination for the new photos folder?

  There is an option called see the import dialog when a memory card is detected under the general tab in Preferences, but there is no option of destination of the file associated with this.

  2. how can I tell Lightroom to leave the original file names as they are (i.e. IMG_2887.CR2) and place them in a new subfolder (i.e. 2011_06_17) in the destination folder (J:\), named after the date of the photo capture (17 July 2011)?

  There are a few options on the management of the files tab in the Preferences, but they do not seem to affect the import of files on the local hard drive.

  3 it maybe should have been the first question really. Lightroom is able to import files from the camera or card to the local hard disk drive at all?

  Of course, I expect to be able to do, but from the looks of him, I'm not too confident in this respect.

  To begin I would just copy my picture files, directly from the camera or a card reader in a destination folder of my choice, in the same way as Canon EOS Utility it. I didn't wat to simply import the files into the Lightroom Catalog and start working with the files directly from the camera or memory card. Hell no! It is not an external drive for the love of God!

  Please advise!

  I think what you want is on the right side of the screen import, down. There is a Destination area. It can be reduced. Just click on the small triangle next to 'Destination' to develop. Everything you need is there.

• Reading/writing data to files in the directory "data" of the application

  I'm trying to write and then read a little data, and it does not work. The size of the file is back by '0' because I wrote the file:

  char* ptr = NULL;
  write_file("./data/test.txt", "testing!");
  read_file("./data/test.txt", &ptr);
  fprintf(stderr, "HERE: %s\n", ptr);
  
  void write_file(char* file_name, char* data)

      {

      }
      else
      {
          fprintf(file, data);
      }
  
      close(file);
  }
  
  int read_file(char* file_name, char** data)

      {
          fprintf(stderr, "Cannot read from file: %s\n", file_name);

          *data = malloc(num_bytes + 1);
  
          fread(*data, 1, num_bytes, file);
  
          (*data)[num_bytes] = NULL;
      }
  
      close(file);
  
      return 0;
  }
  

  Don't know what I'm doing wrong here...

  No idea, but a few tips:

  • Have you created the directory data?
  • Put an exit if the entry is successful, so you can be sure that your code is executed
  • Close the file only if opened successfully
  • Close the file with fclose. Close may not do and cause it is not emptied, the content can be empty. See http://www.cplusplus.com/reference/clibrary/cstdio/fopen/
  • Add a fflush (normally not used) after writing

• Read a file from SD card

  I have problems to read a file from SD card. I watched EmbeddedMediaDemo sample and I changed the line:

  InputStream is = getClass().getResourceAsStream("/media/BlackBerry.mp4");
  InputStream is = getClass().getResourceAsStream("/SDCard/BlackBerry/videos/VID00019.3GP");

  "' and I get the message:" flow Eception exception: null ".

  I also tried so:

  InputStream is = getClass().getResourceAsStream("file:///SDCard/BlackBerry/videos/VID00019.3GP");

  but same problem

  I try to include VID00019.3GP in the proj, then use this line:

  InputStream is = getClass().getResourceAsStream("/media/VID00019.3GP");

  It works.

  Please urgent help.

  Thank you

  Passing the uri is the easiest way.  You can open an input stream of the file using the FileConnection system:

  InputStream inputStream = null;
  FileConnection fileConnection = (FileConnection) Connector.open( "file:///SDCard/BlackBerry/videos/VID00019.3GP");
  if (fileConnection.exists()) {
      inputStream = fconn.openInputStream();
  }

  Thanks for the information

  Hello

  When we try to edit any PDF file that is stored on a MicroSD card, then, first of all, the file must be saved in the internal memory to cause permissions defined by Android for external storage.

  Due to limitations set by Google in Android 4.4 and above, it is not possible to change files that are stored on the SD card in system no App.

• Problem writing external file on the disk mounted outdoors in Windows

  People,
  
  I have a strange problem with a simple OWB mapping where I am dumping the contents of a table to an external file.
  The versions are OWB v 11.2.0.2 64 - bit on Oracle RDBMS 11.2.0.2 2007 Windows 64 - bit Enterprise Server.
  
  When the external files module is connected to a place that point to a local drive and directory on the OWB server, everything works fine - files are created and written.
  When the external files module is connected to a location that points to a disk mounted on another Enterprise 2007 64-bit Windows Server, I get + "path not valid for the target file, check if the connector is deployed correctly. +
  
  The "File System Path location" in OWB is set to "N" (no slash anyway). ' ' Test connection ' reports OK.
  
  I gave the os user Oracle and "Everyone" (for good measure) all rights on the mounted disk, and I see that the package generated code uses the correct directory, and the directory path is correct on the server. The drive mounted (N :) should appear as a local disk to Oracle I see. I am able to create and delete files on the disk using a command line on the OWB/DB server.
  
  I'm scratching my head on this one...

  Hello Haakon,
  try to specify the directory in OWB with UNC path (instead with a letter, as \\other-server\shared-resource of the drive).
  MS Windows sessions for executed OWB mapping and where you map resource network to the drive letter is different - maybe it's a reson why you can't access the mapping file.

  You close your session to the Oracle database server after network sharing the drive letter mapping?

  Kind regards

  Follow-up: I made a boot SAFE and SECURE connection and was able tot save the iCloud, but no other player, including a USB doesn't stick with 'IGNORE the PERMISSIONS ON this VOLUME' of.  I firmly believe that, despite the error message, this is not a problem of file system permissions, it has something to do with the sand boxed apps and my primary UID.  I created a group called family and I made this my main group by using the utility of directory identifier.  I changed then owners on my hierarchy so that my files were all held by the new group ID.  I noticed that the message an error about a file created from a template generated the error:

  05/12/15 6:53:56.350 PM sandboxd [399]: Numbers (76643) ([76643]) deny-read-data file /private/var/folders/x5/3sxc34k13j12nv9twq2_m_fc0000gn/C/com.apple.iconservices store.index

  -rw - 1 personal rfbrost - 7655424 Nov 25 15:25 store.index

  I noticed that the temporary file is created as the ID of Group staff.  Whence the system get this info?  My primary group ID is now family.  It should not important here because the file does not have still permissions RWX group, but it is strange to me.  What is a latent bug that the default group is always personal?

  Finally, I'm able to drag the file created and saved on the disk to my main iCloud file hierarchy and read it very well.  At other times, in a sandbox application, I am able to duplicate the file and save the duplicate but not the original file (called untitled) created from a template.

• Virtualized temporary Internet Files eat up disk space. How can I stop this?

  Have encountered a problem of memory on my C drive and the holding of all recommendations usual cleaning only manages to free a few hundred MB. My hard drive is partitioned into a C and an E drive (each with 116 GB). I use Vista and Internet Explorer. (As far as I know, this is not a problem of RAM and my computer to not walk slowly.)

  The number of programs and files on my C drive not could represent almost 116 GB of memory, but I could find no other possible reason for my low disk space... until...

  I went to the guest orders and managed to do list all in the C drive. Then I spotted a directory which seems to contain a HUGE 94 GB of memory on the C drive. The exact name/address was as follows: C:\users\Kevin\Appdata\Local\Microsoft\Windows\Temporary Internet Files\Virtualized\C\Users\Kevin\Appdata\Local\FLVService. The list of files in this directory have been mainly youtube and almost all the other videos I've seen last year! (This folder does not appear in Windows Explorer.)

  Then, these videos are stored in virtual memory? They take place that much space? (The term 'virtual' throws me a bit). I can delete this file safely and how? And, finally, how to stop what is happening yet?

  So, thank you for reading this far and I would be really grateful for any help on this matter.

  Kevin.

  What problem you encounter when you try to delete the files?  FreeCorder has some options, you can use to purge or otherwise control the cache / repository it uses? That seems to be the easiest way to get rid of files and recover disk space.  Otherwise, uninstall (and reinstall maybe later) may present you with an option to clear the cache, the program uses.
