• How to compress the data in binary file?

  See some games compressed into bin files and a program to extract these files, I don't know how to compress the game binary form files. I'm not a programmer not so no knowledge of coding, if you can tell me a software suitable for this sick work be grateful.

  I want to compress my games strongly and I noticed this binary format a high compression rate, so I want to compress my files in binary format using a program and extract them easily when necessary.

  Hello

  It doesn't really matter for good compression which is the output format, what matters is the method of compression used to compress.

  I tried some of them and the best compression I've seen is called LZMA2, it practically reduces a file size at least 10 times.

  What you can do to use this compression method is to download and install 7zip free http://www.7-zip.org/

  try to compress the original file (use to create the binary file with the extension BIN) with LZMA2 METHOD ULTRA (it's what we call in 7zip) and then compare the output with the binary size and you should see it is almost the same if they aren't better...

  How ever compression takes awhile.

• Adds data to the binary file as concatenated array

  Hello

  I have a problem that can has been discussed several times, but I don't have a clear answer.

  Normally I have devices that produce 2D image tables. I have send them to collection of loop with a queue and then index in the form of a 3D Board and in the end save the binary file.

  It works very well. But I'm starting to struggle with problems of memory, when the number of these images exceeds more than that. 2000.

  So I try to enjoy the fast SSD drive and record images in bulk (eg. 300) in binary file.

  In the diagram attached, where I am simulating the camera with some files before reading. The program works well, but when I try to open the new file in the secondary schema, I see only the first 300 images (in this case).

  I read on the forum, I have to adjust the number of like -1 in reading binary file and then I can read data from the cluster of tables. It is not very good for me, because I need to work with the data with Matlab and I would like to have the same format as before (for example table 3D - 320 x 240 x 4000). Is it possible to add 3D table to the existing as concatenated file?

  I hope it makes sense :-)

  Thank you

  • Good to simulate the creation of the Image using a table of random numbers 2D!  Always good to model the real problem (e/s files) without "complicating details" (manipulation of the camera).
  • Good use of the producer/consumer in LT_Save.  Do you know the sentinels?  You only need a single queue, the queue of data, sending to a table of data for the consumer.  When the producer quits (because the stop button is pushed), it places an empty array (you can just right click on the entry for the item and choose "Create Constant").  In the consumer, when you dequeue, test to see if you have an empty array.  If you do, stop the loop of consumption and the output queue (since you know that the producer has already stopped and you have stopped, too).
  • I'm not sure what you're trying to do in the File_Read_3D routine, but I'll tell you 'it's fake  So, let's analyze the situation.  Somehow, your two routines form a producer/consumer 'pair' - LT_Save 'product' a file of tables 3D (for most of 300 pages, unless it's the grand finale of data) and file_read_3D "consume" them and "do something", still somewhat ill-defined.  Yes you pourrait (and perhaps should) merge these two routines in a unique "Simulator".  Here's what I mean:

  

  This is taken directly from your code.  I replaced the button 'stop' queue with code of Sentinel (which I won't), and added a ' tail ', Sim file, to simulate writing these data in a file (it also use a sentinel).

  Your existing code of producer puts unique 2D arrays in the queue of data.  This routine their fate and "builds" up to 300 of them at a time before 'doing something with them', in your code, writing to a file, here, this simulation by writing to a queue of 3D Sim file.  Let's look at the first 'easy' case, where we get all of the 300 items.  The loop For ends, turning a 3D Board composed of 300 paintings 2D, we simply enqueue in our Sim file, our simulated.  You may notice that there is an empty array? function (which, in this case, is never true, always False) whose value is reversed (to be always true) and connected to a conditional indexation Tunnel Terminal.  The reason for this strange logic will become clear in the next paragraph.

  Now consider what happens when you press the button stop then your left (not shown) producer.  As we use sentries, he places an empty 2D array.  Well, we dequeue it and detect it with the 'Empty table?' feature, which allows us to do three things: stop at the beginning of the loop, stop adding the empty table at the exit Tunnel of indexing using the conditional Terminal (empty array = True, Negate changes to False, then the empty table is not added to the range) , and it also cause all loop to exit.  What happens when get out us the whole loop?  Well, we're done with the queue of data, to set free us.  We know also that we queued last 'good' data in the queue of the Sim queue, so create us a Sentinel (empty 3D table) and queue for the file to-be-developed Sim consumer loop.

  Now, here is where you come from it.  Write this final consumer loop.  Should be pretty simple - you Dequeue, and if you don't have a table empty 3D, you do the following:

  • Your table consists of Images 2D N (up to 300).  In a single loop, extract you each image and do what you want to do with it (view, save to file, etc.).  Note that if you write a sub - VI, called "process an Image" which takes a 2D array and done something with it, you will be "declutter" your code by "in order to hide the details.
  • If you don't have you had an empty array, you simply exit the while loop and release the queue of the Sim file.

  OK, now translate this file.  You're offshore for a good start by writing your file with the size of the table headers, which means that if you read a file into a 3D chart, you will have a 3D Board (as you did in the consumer of the Sim file) and can perform the same treatment as above.  All you have to worry is the Sentinel - how do you know when you have reached the end of the file?  I'm sure you can understand this, if you do not already know...

  Bob Schor

  PS - you should know that the code snippet I posted is not 'properly' born both everything.  I pasted in fact about 6 versions here, as I continued to find errors that I wrote the description of yourself (like forgetting the function 'No' in the conditional terminal).  This illustrates the virtue of written Documentation-"slow you down", did you examine your code, and say you "Oops, I forgot to...» »

• How to save data in the text file of Spartan 3

  Hi all

  I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

  could you please help me with this

  Thank you

  Rania

  Hi David,

  Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

• Save data to file, and Time Stamp String

  Hello

  My vi use producer/consumer architecture, and when I changed to a regular while loop for two loops he stops writing the data in the file at the end of execution. It creates two files (one for data) and one for the timestamp. Could it be because that the stop on the loop of consumer control (where I save the data) is a local variable (the control itself is on the producer of the while loop)?

  Thank you

  I'm sorry, that was my mistake. I don't connect the wires in the wrong case structure.

• How to determine the size of the binary file data set

  Hi all

  I write specific sets of data in table in a binary file, by adding each time so the file grows a set of data for each write operation.  I use the set file position function to make sure that I'm at the end of the file each time.

  When I read the file, I want to read only the last 25 data sets (or numbers).  To do this, I thought using the position set file to set the file position where it was 25 sets of data from the end.  Math easy, right?  Apparently not.

  Well, as I was collecting data file size as I began the initial tet run, I find the size of the file (using file order size and get number of bytes so) as the size increases the same amount every time.  My size and the format of my data being written is the same every time, a series of four numbers double precision.

  I get increments are as follows, after the first write - 44 bytes, after 2nd - 52 bytes, 3 - 52 bytes, bytes 44 4th, 5th - 52 bytes, 6 - 52 bytes, 7th - 44 bytes and it seems to continue this trend in the future.

  Why each write operation would be identical in size of bytes.  This means that my basic math for the determination of the poistion of correct file to read only the last 25 sets of data won't be easy, and if somewhere along the line after I've accumulated hundreds or thousands of data sets, what happens if the model changes.

  Any help on why this occurs or on a working method, all about the problem would be much appreciated.

  Thank you

  Doug

• Error message on Windows XP, "Windows-Delayed Write failed, windows was unable to save all the data for the file.

  I use windows xp as the operating system. I bought the new 3G huawei data card. While surfing internet, between a pop-up is displayed

  «Windows-delayed write failed, windows was unable to save all data in the file C:\Documents and settings\new\Local Settings\Application Data\Google\Chrome\User Data\Default\Session Storage\004285.log.» The data has been lost. This error can be caused by a failure of your computer hardware.

  After this computer freezes and I have to restart my computer. Please help me how to fix this problem.

  The error basically says that he tried to write something on your hard drive and for some reason that unfinished write operation.  This could indicate a bad sector on your hard disk, damaged disk or a problem with your hardware.

  Whenever a problem involving a disk read or write appears, my first approach is to perform a verify operation of the disc to the hard drive.  Even if this is not your problem, it is a step of good routine maintenance. Run the disk check with the "/ R" or "Repair" option.  Note that the real disk check will be presented at the next reboot, will run until Windows loads completely, cannot be interrupted and can take more than a few hours to run depending on the size of your hard drive, the quantity and type found corruption and other factors.   It is better to perform during the night or when you won't need your computer for several hours.

• Write delay failed unable to save all the data for the file $Mft

  Have a frustrating problem.  Help is greatly appreciated.  Learned the hard way and lost a dwg important issue which was unrecoverable.  Bought a new drive external hard seagate.  Could not back up the entire system with software pre-installed.  Download acronis true image home 2011.  Tried to backup system.  Receive error when trying to backup messages; 'Delay to failure of Scripture; Reading of the sector; Windows was unable to save all the data for the file $Mft.

  I don't know where Microsoft 'Technical support engineers' get their information.

  Write caching without a doubt "does apply to external hard drives", but it is usually disabled to prevent to sort the problem you are experiencing.

  I've seen several positions reporting to the same question that you do.  All of these positions were with SATA drives.  Is your Seagate eSATA drive?

  The disc is recognized as an external drive in Device Manager?  In Device Manager, go to the drive properties dialog box and click the policies tab.  An external drive should have two options: "Optimize for quick removal" and "Optimize for performance".  An internal hard drive shows the options as gray (with 'performance' selected), but there should also be a checkbox "Enable disk write cache" under the second option.

  What shows in your policies tab?

  If I understand correctly, "writeback" or "write behind" is implemented by disc material or its pilot.  If the option is not available on the drive properties > policies tab, I would suggest to contact Seagate support.

  Hello

  As I said on your other thread:

  In order to write in the shared directory/documents, your application should request action "access_shared" and it must be granted by the user. Make sure you have

  access_shared

  in your bar - descriptor.xml.

  Also note that the shared documents folder may not be the best place to write the application log data. There is one connects / in the sandbox to this effect, or the application directory data / directory if the information should be persisted. The documents/shared/folder is designed for documents that the user creates or interacts with.

  HTH,

  Christian
