• Error on image from the server and display streaming

  Hi all

  Im trying to read an Image that origin of the server and displays on a screen

  Here's the code I'm using to broadcast the image.

  It is streaming on my Simulator as well as on some devices.

  But on some devices, it's not streaming and throw an exception.

      }
  
      return null;
  }
  

  The underlined part of the code is where the uid is sent as public _.

  Please, look in the code and let me know where the error is, or is there a better way to disseminate the image.

  In the hope that you hear.

  Thank you & best regards

  Krishnan

  Hello

  I found the error.

  It's in the URL sent by the server.

  The URL consisted of http://google.com

  But the format required to retrieve the image on several device would be http://www.google.com.

  Thanks for anyone who tried to help him.

  Hello

  It is more a question of support Adobe Stock for a user.

  I downloaded a few images from the CPD and sent an email to do the download.  Since the conversion window Adobe was already open, I didn't cancel the Adobe window.  How can I access the images associated with the links?  I can access is no longer as there is no code.  I didn't know that the images already chosen by download would be unavailable.

  Thank you

  Craig.

• How to download an image in the folder and view using MySQL?

  Hello

  I want to create a page where a user can upload a picture and then I want to keep the details of the image in MySQL and PHP dynamic text allows you to display the image. Is it still possible? I have so far failed in my quest to find help on google or anywhere else besides.

  Basically what I want to do is create a page where the houses/lodges can save their information: name of the institution, Image of the institution, location, website, price range, etc. I want to allow them to download a picture from their school and the download location to a folder and, as I mentioned earlier, store only the information required to retrieve and display the image in the MySQL DB. Then, when a customer uses the search page, I want to display the results in a way that will allow them to see the image beside the name.

  Please PLEASE please someone help me I will be more than very happy. If someone has a script they let me use or at least a good tutorial or a link to worthy of information please let me know.

  Thanks in advance.

  Cedric

  There are many facts about PHP scripts or tutorials out there (google 'PHP file upload') that help you download the files in a directory on your server, but I ve never pinned scripts/tutorials that are a little "specific Dreamweaver' and you say how to integrate this functionality with insert/update server behaviors recording existing and even save info to files in a database.

  At this point, you can consider using an extension of Dreamweaver as PHP X Upload (by FelixOne) which seems to satisfy all the requirements you mention.

  See you soon,.

  Get rid of PC Cleaner

  I'm trying to download Security Suite from my provider and I get a message that I have to get rid of PC Cleaner. I searched my PC and that you do not find PC Cleaner. If I don't know how I'll remove it. Thanks for your help. The only reference to PC Cleaner is the Microsoft Security on the PC.

  Go to add/remove programs and see if PC Cleaner is in the list. If so, then click to remove.
  Then go into Windows Explorer. Research on Windows/System32 and see fi there is pcsd.dll and delete it.
  Then go to regedit and search for any mention of PC Cleaner, PC Cleaner and remove these entries.

  Change the settings of the REGISTRY can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the REGISTRY settings configuration can be solved. Changes to these settings are at your own risk.

  Then see if you still get an error of PC Cleaner.

  Let us know if that helps.

• Loading/downloading the images from the camera

  I downloaded the images from the camera to the computer, then accidentally deleted from the memory card.  Move them back to the memory card?

  I downloaded the images from the camera to the computer, then accidentally deleted from the memory card.  Move them back to the memory card?

  =====================================================
  FWIW... this task is easier to do than to explain.

  (1) connect the camera via a USB cable and turn it on... or insert the memory card in
  your Media Player.

  (2) go to... Start / my computer... your camera should be attached to a drive letter.
  The reader should be recognized as one or several removable disks... it can
  have several drive letters.

  Removable disk (e :))
  Removable drive (g)
  Removable disk (h :))

  Left 3) click on drive letters... When you identify the drive letter for the camera or
  Media Player... (it will be one that does not launch a dialog box indicating:)
  Please insert a disc in the drive?) ...

  Follow these steps...

  4) navigate to the folder in which the photos are... Open it and go... Edition/select all... good
  Click the group selected (highlighted), then from the menu choose... Send to /.
  Removable disk?

  Only a limited number of files can be copied to the root directory of the card... if you
  Transfer lots of pictures... they must be in one or more folders.

  If these files have been changed in any way, rename, rotate, changing the brightness...
  No matter what... the camera will recognize them is no longer, but they will always be on the map
  If you want to use as a backup. You can click on the left to see what is on the drive letter
  the map.
