Strange behavior when reading binary file

Similar Questions

• You want to read binary files in some parts of the 500th row in the 5 000th row.

  I have files of 200 MB of 1000561 lines binary data and 32 columns when I read the file and sequentially conspire full memory of the generated message.

  Now, I want to read the file in pieces as the 500th row 5,000th row with all the columns and it draw in the graph.

  I tried to develop logic using functions file advanced set file position and the binary file reading block, but still not get the sollution.

  Please, help me to solve this problem.

  Thanks in advance...

  Hi ospl,.

  To read a specific part of the binary, I suggest to set the file position where you want to read the data and specify how many blocks you must read binary file for reading binary file.VI

  for example, if you write table 2D binary file, and then mention you data type this 2D chart and make your account (5000-500). Then together, you produce position. If you have 32 DBL data type and column then it is 256 to the second row and 256 * 500 for line 501th. Use this number as input into your position.vi file get.

  I hope you find you way through this.

• "Read binary file" and efficiency

  For the first time I tried using important binary file on data files reading, and I see some real performance issues. To avoid any loss of data, I write the data as I received it acquisition of data 10 times per second. What I write is an array double 2D, 1000 x 2-4 channels data points. When reading in the file, I wish I could read it as a 3D array, all at the same time. This does not seem supported, so many times I do readings of 2D table and use a shift with table register building to assemble the table 3D that I really need. But it is incredibly slow! It seems that I can read only a few hundred of these 2D members per second.

  It has also occurred to me that the array of construction used in a shift register to continue to add on the table could be a quadratic time operation depending on how it is implemented. Continually and repeatedly allocating more larger and large blocks of memory and copy the table growing at every stage.

  I'm looking for suggestions on how to effectively store, read effectively and efficiently back up my data in table 3-d that I need. Maybe I could make your life easier if I had "Raw write" and "read the raw data" operations only the digits and not metadata.then I could write the file and read it back in any size of reading and writing songs I have if you please - and read it with other programs and more. But I don't see them in the menus.

  Suggestions?

• Work of doesn´t of reading binary file on MCB2400 in LV2009 ARM embedded

  Hello

  I try to read a binary file from SD card on my MCB2400 with LV2009 Board built for the ARMS.

  But the result is always 0, if I use my VI on the MCB2400. If use the same VI on the PC, it works very well with the binary file.

  The
  access to the SD card on the works of MCB2400 in the other end, if I
  try to read a text file - it works without any problem.

  Y thre constraints for "reading a binary file" - node in Embedded in comparison to the same node on PC?

  I noticed that there is also a problem
  with the reading of the textfiles. If the sice of the file is approximately 100 bytes
  It doesn´t works, too. I understand can´t, because I read
  always one byte. And even if the implementation in Labview is so
  bad that it reads the total allways of the file in ram it sould work. The
  MCB2400 has 32 MB of RAM, so 100 bytes or even a few megabytes should
  work.

  But this doesn´t seems to be the problem for binary-problem. Because even a work of 50 bytes binary file doesn´t.

  Bye & thanks

  I know that you have already solved this problem with a workaround, but I did some digging around in the source code to find the source of the problem and found the following:

  Currently, binary read/write primitives do not support the entry of "byte order".  Thus, you should always let this entry by default (or 0), which will use the native boutien of the target (or little endian for the target ARM).  If wire you one value other than the default, the primitive will be returns an error and does not perform a read/write.

  So, theoretically... If you return to the VI very original as your shift and delete the entry "byte order" on the binary file read, he must run a binary read little endian.

  This also brings up another point:

  If a primitive type is not what you expect, check the error output.

• Help reading binary file

  Hello

  Just hoping someone might be able to help me with the following. I'm new to labview and don't do not have has IT melts so understand binaries and how to read is beyond my capabilities.

  Quite simply, I try to open a series of binary files written in the following format (see attachment data.txt) then in labview, process the data. I tried the examples of binary file reading but seem to be long around in circles. I also enclose examples of the 8sept4.3ld of file format, then the same file in an ascii format which is what I'd like the output in labview to look like.

  I'd appreciate any help with this, especially if it's stupid guide!

  See you soon,.

• Issues coming out of "sleep mode" and strange behavior when restarting with GPU

  I use a desktop computer HP P7-1240 completely stock except for a GPU EVGA GeForce GTX 750 TI SC. The GPU works well when the computer is running (which is strange because the forums have several other discussions mentioning the 700 series must be incompatible with my BIOS).

  However, there are two main strange problems that have arisen since the installation of the GPU. One is that, every time that the computer enters mode "sleep", he refuses to wake back up correctly. It seems to me that the computer active but sends all the signals back panel (at the very least, no video because my monitors remain blank). On rare occasions, he wakes back correctly, but at least 90% of the time, it must be restarted. Upon reboot, the same problem sometimes (not), and the computer must be rebooted a second time until it will start again.

  This leads to the second problem. During startup, the computer goes to a black screen, listing the specifications of basic computer skills (see attached photo. In this screen, the computer does not meet any entry.  He proceeds to beep 3 times, all the same length and height spaced about 30 seconds of gap. After the third beep, the screen goes black and then the computer starts normally with no other strange behavior.

  Without the GPU, none of these problems occur. At the very least, not regularly.

  I saw another thread mentioned that, while the HP support for my office page lists not her, there is an update of the BIOS for my motherboard which has fixed issues related to the GPU more modern. By nature it is an update of the BIOS that does not (seem to) officially support Windows 7, I am reluctant to go forward with this potential solution.

  Although I intend to build myself a new computer from scratch at a certain point, I was hoping to get at least another year out of this machine, if not 2.  While this question does not seem to be immediately threatening the stability of the computer, I can't help but think that it is a question should I go quickly to avoid future problems (not to mention it would save me a good amount of electricity to be able to enter the mode 'sleep' on a regular basis).

  Any suggestions would be greatly appreciated!

  

  Problem has been solved!

  For those of you who have trouble sleeping with the p7-1240 or computers with a card mother identical (MSI Jasmine Ms 7778 ver 1.0), I suggest that you follow this thread:

  http://h30434.www3.HP.com/T5/desktop-hardware/unable-to-boot-with-new-graphics-card/TD-p/3930544/highlight/true

  It is to use an update for your BIOS that is intended only for PC under Windows 8, but that seems to work perfectly well with Windows 7 PC. It solved my problems of sleep and makes the computer to behave at least semi normally while restarting.

  However, as indicated in the wire, an update of the BIOS should be a last resort because it can turn your machine into a very heavy and expensive paperweight if something does not work. Do not forget that you have the worm 1.0 card mother MSI Ms 7778 Jasmine and remember that you update the BIOS version 8.18.

  As I am looking for 2aeo on HP.com currently (according to the thread leading up to), I'm not find the same links I found last week when I went through the update. However, you can find elsewhere.

• Java Fx: strange behavior when trying to write a vertical label

  I've noticed some strange behavior on the rotated texts (Label,...) in JavaFx...

  Originally, I just wanted to be able to display labels vertically in a GridPane. The first problem is that there is no simple way to indicate a label to display its content in one direction and given orientation. It would be nice to have something like the property on the side of the tabPane allowing to easily turn the text...

  In any case, I quit then myself to use the rotation function to turn my Label. It's when the strange thing began to happen... I put my label in a cell of the grid that is not large enough to display the full text if it is not turned, but the text must be able to adapt rotated once. The problem is that the text appears wrapped even when it is turned as if packaging test have been done until the text is actually shot... The problem can be seen on this screenshot http://hpics.li/e210f2f : the text to be displayed is written in the ToolTip and we can see that only the first letter of the rotated text is displayed in the grid of the cell even if there is more than enough space to display all...

  Anyone has an idea on how to solve this? Is this the intended behavior or it's just a small bug?

  Thanks in advance for your answers.

  Another workaround solution seems to be to wrap the labels into groups and spin groups. If you don't have enough space in the grid, although bad things happen.

• 2.1 RC1 - strange behavior when you change the data in the table

  I recently found a new strange behavior of the SQL Developer. On a small table or a table with a filter where all the data is loaded, but not all lines can be displayed on the screen, trying to change the data in the table. When I confirm the editing with the key enter, Developer SQL jumps always until the end of the data. Quite confusing and boring. The cursor seems to remain in the field that I have edited, then moving upward or downward line force SQL developer to this line.
  
  Appears not to be the case when all the data are loaded instead of punch, but if you force Developer SQL to load all the data, I can reproduce this strange behavior.

• Read binary file

  Hello, I would like to write and read a 2D in a binary table. I get an error in my VI and I have no idea how to solve this problem. Can someone help me?

  In addition, the file extension should be .bin or. dat.

  Thank you

  Zied

  You really need to add the size of the array.  Otherwise you will have no idea of what should be the size of your two dimension.  Then just do a simple reading with a 2D data type table.

  

• BlackBerry 10 functions and characteristics of strange behavior when sending messages/text

  Feature: Passport

  I noticed that some contacts/recipients did not of texts intended for them.

  I sent a test text to a contact. He replied stating that he had not received the text, but when I decided to send a reply message to it, he has been received!

  Is it possible to return to the default settngs to the Messages Settings\Text Hub? Maybe someone has encountered this and has a solution or could suggest a few things to check?

  ATTENTION: Interested readers.

  I think I discovered why some text messages have not been received.

  I noticed when I looked in question contact the House or fixed telephone number is first on the list (to use) and when I looked then the texts themselves, Contact was saying was the number sent.

  Yes it is possible.  Let's not your date mask.  You're masking for 12-hour format when your data is in 24-hour format.  Change the mask of your date to be "YYYY-mm-dd-hh24. MI.ss ".  Notice the change in "BOLD".

• Strange behavior when creating a composite with ' without validating key. '

  Hi all
  
  It's very strange for me. Can you please tell me where I am wrong.
  
  I want to create a composite key for the combination "INT_ID" and "STO_ID" columns in the table "act_ord". because this table contains already more entries in double for this combination, I decided to use 'enable novalidate' to skip validation for records duplicate already existing while creating constraints. But I get the following error "ORA-02260: table can have only one primary key" executing the below statement 1.1. If I create a 1 column with option novalidate constraint means, its working fine.
  

  1.1 Not working:- Giving error ORA-02260: table can have only one primary key
  ALTER TABLE ACT_ORD ADD CONSTRAINT PK_INT_ORD
   PRIMARY KEY   (INT_ID,STO_ID) enable novalidate 

  1.2 Working without any error:
  ALTER TABLE SPL_VAS.ACT_ORDER ADD CONSTRAINT PK_INT_STO_ORD
   PRIMARY KEY   (INT_ID) enable novalidate

  Is there a limitation of use 'enable novalidate' with the creation of composite primary key?
  
  Please take the necessary steps and make your suggestions.
  
  Kind regards

  It is clear to me why you get this error. Here's a unit test where I get a different error (more logical).

  Note: to do this, you must first create a NON-unique index on the columns that you want to be in the primary key. Then use the clause for INDEXING to HELP when you add the primary key.

• Strange behavior when using groupspec in netstreams.

  I started using the groupSpecifier to connect two players in a game I'm developing. Before, I was using a server to swap their farID, now I use the groupSpec netGroup, and it works well... but I got this weird problem:

  The first seconds of 2 to 8 netStream.sends command, I got like 2 seconds delay, after that, communication is almost instantaneous.

  Don't know why this is happening, but I don't want to fully implement netGroup if I'm having this kind weird behaviors...

  All do not know why this might be happening?, when I used NetStream.DIRECT_CONNECTIONS it didn't happen.

  Thank you.

  Update: looks like it's not about how long I have to wait for it to start working properly, it's how sends commands I do (between 0 and 10, seems completely random).

  the delay you see is the delay "pull" mode, while the Group relies (trivial) latency minimum spanning tree for the multicast stream ' push' mode.  probes need push mode any quantity rate data as well as the time to move from the probes to be judged.
