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!

CEP has an API to access Local file.

    This is the default location is "C:\WINDOWS\Minidump.

    Specifically, I have no problem in real-time, but I want to know about it.

    I have also noticed that some MVP suggest that you download the minidump & they inspect it. But how do?

    Do not hesitate to make the technical content, I will try to understand that also.

    I have no OS dependencies so here you can chat on any OS (XP, Vista, win 7).

    It would be good if you give me an example. As an example you can quote all the minidump pre inspected which is uploaded to skydrive files.

  • How to read the file in db sqlite of assets?

    (2) DatabaseFactory

    Does anyone know how can I write the path to the db file in the current folder by one the above cases?

    I thank very you much.

    You have write access to the active folder ONLY when you're in development mode.

    In an application signed output, the entire application / folder tree is unalterable to your application (and not accessible to other applications).

    See http://developer.blackberry.com/native/documentation/bb10/com.qnx.doc.native_sdk.devguide/com.qnx.do... for the background.

    If you want to change such a data base, you must add logic to copy in the application data / folder is the first time the app tracks, or (optional, if it a such writing can never occur for most users) only when you first need to make changes.

    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

    And when I listed the permissions: imac-5 k (1): com.apple.iconservices rfbrost$ ls - ö @

    -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.

  • How to read two files (one updates every second, the other is constant) simoltaneously

    Dear all,

    I'd appreciate if someone help me.

    I want to read two files, one is the temperature that updates every second, and the other is energy hysteresis that has specific lines and is constant.

    I had a program in the discussion forum to read a file as it is updated. I checked this program in my case and it works.

    Then I added playback file hysteresis energy to the existing file. But while I run the program, the energy hysteresis file is read with all the lines.

    But the goal is that every time the updates of the temperature, I need to read a line of the file hysteresis energy.

    in this way every second, so, I have a new temperature data and a row of the other file.

    I tried to use 'for loop' inside the program, but it did not work, because the temperature reading will stop until that end of the loop.

    I joined the program.

    Could someone help me how read only a row of hysteresis energy file every time that the temperature updated?

    IS that what you wanted to achieve?

  • Read/write file in Unicode (UTF-16)

    Hi, I have a problem to write a file in Unicode (UTF-16)

    I have to read a file with LabView, change some settings and write the new data in the same file. The file uses Unicode UTF-16.

    I downloaded a few library here: https://decibel.ni.com/content/docs/DOC-10153

    I can read the file, convert the data to ASCII/UNI/UNI and then write the file. But when I open the new file with an editor like Notepad ++ there is some unexpected characters at the end of the line.

    Even read the file and write exactly the same doesn' data not work.

    I've attached an example.

    Thanks for you the kind of support.

    Right click on your functions read and write text files.  There is an option to "Convert End Of Line".  Who turned off the two functions.

    As a side not, you need not close file functions.  The functions Read and Write Text File will close the file that reference output file is not connected.

  • Read/write file binary change greater than 128 bytes.

    Hi all, maybe a strange question, but I'm scratching my head on this one. There is undocumented behavior in the function of read/write binary file, where U8 a value greater than 128/0 x 80 get automatically converted to 0x3F value?

    I try to use LabVIEW to generate a binary file custom that we'll load in an EEPROM, so all data in the binary file is stored as values of U8. I have a "template" file, and eventually I'll take the logic implemented to replace the fields with the data from the true value. However, I am struck by the anomaly that when I just read the file in LabVIEW and then réécrirait, all the values 0x80 and more are truncated to 0x3F value. Has anyone seen this before, and is there a solution?

    I noticed writing the value 0 x 80 directly to one generates a binary file (such as a U8) 0 x 90, 0 x 70 being written in the binary file. It is also rather undesirable, as it adds additional bytes in the bytestream, and the bytes of EEPROM must be in exact locations.

    Join your data file.

    This program is to give the images below?  Are you sure that LabVIEW is to write the bytes differently?  I really doubt that.
