• Base64 encode and decode

  Hello

  I use opennssl for encoding and decoding base 64 and face to face some of the question, he refuses to randomly to encode or decode, to give me a result of 0 and not false BIO_SHOULD_RETRY... I'm trying to put the call in a while if return 0, but it does not work and so I can not decode or encode more...

  The code I am using:

  uint8_t* Tools::base64(uint8_t *input,  uint32_t length)
  {
          BIO *bmem, *b64;
          BUF_MEM *bptr;
  
          b64 = BIO_new(BIO_f_base64());
          BIO_set_flags(b64, BIO_FLAGS_BASE64_NO_NL);
          bmem = BIO_new(BIO_s_mem());
          b64 = BIO_push(b64, bmem);
  
          // write data
      bool done = false;
      int res = 0;
      while(!done)
      {
          res = BIO_write(b64, input, length);
  
          if(res <= 0) // if failed
          {
              if(BIO_should_retry(b64)){
                  continue;
              }
              else // encoding failed
              {
  
                  qDebug("error while encoding base64");
                  done=true;

  Hello
  
  Do we not have out-of-box solution in OSB decode XML that is encoded in URL and encode XML to the URL encoding. If yes how can I do.

• Y at - it a fix for leak of VRAM in Windows Desktop? (Windows media Encoder and photo IE10 Viewer are the root of the problem)

  It seems that Windows media Encoder and photo IE10 Viewer are the root of the problem, and it is about the whole MS Platform in desktop for what anyone associated media.  As easy as it is to use another browser or image viewer I find I like the windows photo viewer ability to preview multiple images and IE10 and 11 are more now then fix everything that exists.

  The issue is having to restart or log out and back in just pass leak VRAM that can go up to 1400 MB and count. What said GPU - Z and ESTR.  The memory of the system seems to be in check most of the time.  Get off my GPU memory Windows.

  I mean leak even with the left running only windows desktop and essential tasks to keep it that way.  I have games that will never saturate 1.5 GB of video memory on my setup. Darn Far Cry 3 does not work.   I'm ranting, namely. At the same time being a little in-depth play play of this recurring problem.

  In case the VP and general manager or anyone else to Microsoft is approaching through it all here is the short version:

  Video memory leak in Windows 8. How can I fix this in the Windows desktop. Is there a way to erase the GPU cache and reduce the use VRAM 160MO? is there a fix? is there a value from regedit?

• How to check a Svchost.exe high memory usage and troubleshoot?

  How to check a Svchost.exe high memory usage and troubleshoot

  Beautiful Basu 'ASK ',.

  I think I know the answer. Visit this link

  And you can download SvcHost Viwer here.

  Run the following command from cmd: tasklist/SVC /fi "imagename eq svchost.exe".

  Focus on the PID that is causing the high CPU.

  Run SC Config = own Type for each service under this PID. It will launch each service with a separate svchost.exe.

  I would recommend for a complete AV scan.

• Double retroactive loop via an encoder and a tachometer

  I'm building a human rotating Chair for research purposes and want to use a double retrospective loop to remove the backslash. The current system, however, includes only 1 Encoder on load (President) and 1 tachometer and the engine due to the geometry of the system, I can not put an extra Encoder on the motor. I would like to know if there is a controller of axes OR which may take a signal encoder and tachometer signal (speed - analog signal) to close the double loop retroactive.

  Please refer to the attachment for the functional diagram of the system.

  Thanks for any help.

  Hi Ron,

  Based on your schema, I don't see a way to do - are you willing to do all the control without firing the values in LabVIEW?  If so, then I don't see a way to do this.  If you pull the tach values in LabVIEW, you have more options, but none is as complete, having a second encoder.

  All movement PCI cards offer analog inputs, so that you could potentially play in the tachometer signal.  However, what kind of signal it is up?  If its RPM, there is a bit of calculation to actually determine the velocity and I worry not with that many steps in the software, you will kill any 'control loop price' that you may have.  I don't think that the system would be too sensitive if you have to shoot these values in the software; and unfortunately it is not "currently a movement card that reads these signals directly."

  I hope this helps.

• Retrigger encoder and acquisition of analog input on the spur of Z?

  I have a card PCI-6232 and use THIS angular Encoder on the counter 1 to provide a base mean angle for Internet high speed (50-100 kHz) measures the analog voltage.  I use a period of CI on counter 2 to measure the duration of the impulse of Z to determine the length of each measure.  It kinda works, but the result is somewhat contradictory.  I get about 1 in three cycles without encoder data.  I need to find a way to trigger the acquisition to record data for each cycle trigger on the pulse of Z.  If you know another way to do this I'd be open to that as well.  Thank you, Steve

  Hi Sara,.

  Thanks for your reply.  What I wanted to do was to trigger an analysis of the encoder and an entry at the same time triggering the pulse of z analog encoder.  It took a lot of digging through similar samples and after a week of fighting, I thought about it tonight.  I'll post this once I clean up the mess.  Problem solved thanks to dozens of you ad info and samples!

• services.exe memory consumption and therefore 15 minutes to start

  services.exe memory consumption and therefore 15 minutes for bootProblem Description: it seems that since the installation of updated KB973687 my Dell Inspiron 640 m takes an age to start. I am running XP SP3 with all updates installed, have 2 x 512 MB memory installed and the basics of microsoft security is enabled and no virus detected.

Maximum memory use reaches about 500 000 to 600 000 k and the size of the virtual memory increases to more than 2,000, 000 k. Once the VM reached approximately 2 200 000 k it starts to release very slowly and finally reduced to a size of about 6 000 - 7, 000 k, then just a race of user object. It is not until that time where the system becomes usable. What is happening at each startup and lasts about 15 minutes for the system be usable. I have read many articles on this issue, and the other that a clean reinstall which I do not, cannot find a solution. Your help would be greatly appreciated. Operating system: Windows XP

  Your list is very different and much longer than mine. My first thought is that you have the programs loading at startup that might as well load up on request. A useful tool for watching the startup items is Autoruns.

• Problems pictures copies of Flash memory card and USB drive under Vista 64 files

  Hi, when I insert a flash memory card (SanDisk 8 GB SDHC or SanDisk 2 GB Compact Flash) either by inserting the card into a card reader, AutoPlay comes on but the image transfer stops after a few images have been copied to any program (Windows, Picasa, etc.). I chose to copy the files. Same experience when I connect the camera with the memory card in the camera using the USB cable to the PC. I tried to re - format camera memory cards, but it has no effect.
  Also, I feel the same when I try to copy from a USB flash drive (the drive is basic, not a U3 key).
  I have a HP Pavilion m9400t Elite desktop running Vista Home Premium 64-bit. I own this desktop computer for a year and I've always had this problem. I have no problem using these flash memory cards and a USB drive on my old XP PC or an Apple Mac Book. For what I can tell, my Vista desktop is set for automatic windows and updates from HP. Everything about the plan of updating drivers, etc., which would solve this problem would be appreciated.
  Thank you
  Srini

  Hi Srini,

  one) that you get specific error messages when images are arrested to copy?

  (b) what is the file format of the pictures\files that are not copied? What images are copied with success?

  To narrow the problem, please follow the steps mentioned below:

  O copy the pictures manually on the flash memory card Office.

  O connect the flash memory card\ camera to the back of the computer (for a different USB (port universal serial bus) and try to copy the pictures\files.)

  O check if the photos are in double version:

  Windows detects your newest pictures and doesn't matter the duplicate versions of the old photos that you've already copied to your computer

  Hello

  The attached file of the DMP is to bug checking THREAD_STUCK_IN_DEVICE_DRIVER (ea) .

  This indicates that a thread in a device driver that runs constantly.

  Essentially, a device driver is rotating in an infinite loop, most likely waiting for hardware to the idle state. This usually indicates problem with the hardware itself, or with the incorrect programming hardware device driver. Often, it is the result of a bad video card or a bad display driver.

  Video various AMD/ATI driver called ^^, outside of Direct X MMS and/or core.

  ---------------------

  1. make sure you have the latest video card drivers. If you are already on the latest graphics card drivers, uninstall and install a version or a few versions behind the last to make sure this isn't a last number one driver. If you have already experienced with the driver of the card later and earlier versions, please try the driver beta for your card.

  2 in your list of drivers loaded, dtsoftbus01.sys figure who is the driver for Daemon Tools. Daemon Tools is a very popular cause of BSOD in 7/8 base systems. Please uninstall Daemon Tools. Alternative imaging programs are: MagicISO, Power ISO, etc.

  3 if you are still blocked after various troubleshooting and #2 display driver, the video card itself you have recently installed is defective.

  Kind regards

• C240 M3 blocked "memory configuration and test..."

  Hello

  This server was returned by just us to Cisco, which had lent because it was new.   We try to return to service, but have encountered the following problem.

  At first startup, the server receives as much as 'memory configuration and test..' message.  Just this message, it shows no progress in actually memory test.   After a few seconds it turns off, and then turns upward again, repeat that a few times before sit down you with the "memory configuration and test.." message at the top of the screen, but now also showing the address IP of MMIC inside.   The four led above the power button shows green fixed and switch ID unit than the blue LED power buttons, as they should.

  I can get to the MMIC login screen, but the password to the default password so can't get farther in this direction until we discover the new username/password details.  Unless anyone knows how to reset the default MMIC.

  I tried the following recovery steps...

  (1) if we set the J2065 ' Clear CMOS' jumper, the server doesn't work.  It powers up to the day before, but does not respond when you press the power button.

  (2) to the "recovery" of the J2068 rider don't seem to have any effect, the server does not read the USB key recovery file.

  Any ideas?

  Thank you

  Tony S

  I remove the CMOS battery for a while, put back in place, try again and if still nothing... I would look for a motherboard replacement.
