• Get a string from a selected path

  Hello

  I have the following piece of code in my script (which works fine)

  Dim result: result = DirListGet ("C:\","*.adf","filename","FullFileNamesRecursive")

  Instead of simply using the phone book "C:\". ", I would like to invite the user to choose one.

  I tried to use Application.DlgPathSelect as PathNameGet select a path, but I don't know how to put a string representing the path selected in the above DirListGet method.

  Thanks in advance,

  Omar

  Hello Omar.

  Use it like this

  If "IDOk" = PathDlgShow ("select a directory for the adf files", "C:") then
  
    Dim result: result = DirListGet (OutPutPath, "*.adf", "filename", "FullFileNamesRecursive")
  
  end if

  Here is my code...

  I have 3 files in my directory... When I run the code I can open a file and read it... but the while loop get blocked after the first iteration... can someone me help or give some indications

  try {}

  FileConnection fc = Connector.open("file:///store/home/user/documents/BSM/") (FileConnection); "

  If (fc.exists ()) {}

  Enumeration e = fc.list ();

  While (e.hasMoreElements ()) {}

  }

  If (fconnRead! = null) {}
  try {}
  fconnRead.close ();
  } catch (Exception e) {}
  System.out.println (try ());
  }

  }

  }

  You can recode this treatment so that it uses only:

  e.nextElement ())

  Once a loop iteration.

  Directly at the start saying something like:

  String fileName = e.nextElement ());

  and use fileName everywhere in your loop.

  Also be aware that printStackTrace() will do nothing in your situation, it only works if you catch Throwable.  So make sure you something output all your catches exception and also have a catch (Throwable t) to catch the things you miss, as follows:

  {} catch (Throwable t)

  t.printStackTrace ();

  System.out.println ("Eception exception:" + t.toString ());

  }

  I think your code is thrown an exception and you don't see it.

• How to get the external Bitmap of URL object

  Hi all!

  I'm a developer starting with components of BlackBerry, I try to get a Bitmap of the outer object
  URL, but my getImage method does not work correctly. I think that the problem lies in the getImage method. just at the moment where I try to
  create form of Bitmap bytes. Note: J2me with the Image object, that it works!

  could someone help me please?

  Sorry for my bad English & thank you for helping me!

  Code:

  SerializableAttribute public class MainForm extends form {}

  private String url = "http://user-xxxx/json.js";
  private String [] imageURLs = new String [5];

  public MainForm() {}

  try {}
  getJSON (url);
  } catch (IOException e) {}
  e.printStackTrace ();
  }

  try {}
  Add (GetImage(this.imageURLs[0]));
  } catch (Exception e) {}
  e.printStackTrace ();
  }
  }

  Public Sub getJSON (String url) throws IOException {}
  StringBuffer sb = new StringBuffer();
  InputStream is = null;
  HttpConnection hc = null;
  try {}
  long bytesLength = 0;
  int ch = 0;
  HC = (HttpConnection), Connector.open (url);
  is = hc.openInputStream ();
  bytesLength = hc.getLength ();
  If (bytesLength! = - 1) {}
  for (int i = 0; i)< byteslength;="" i++)="">
  If ((ch = is.read (())! = - 1) {}
  SB. Append ((Char) ch);
  }
  }
  } else {}
  While ((ch = is.read (())! = - 1) {}
  bytesLength = is.available ();
  SB. Append ((Char) ch);
  }
  }
  parseJSON (sb.toString ());
  } {Finally
  is. Close();
  HC. Close();
  }
  }

  {} public void parseJSON (String sb)
  try {}
  JSONObject jo = new JSONObject (sb);
  If (jo! = null) {}
  JSONObject channel = jo.getJSONObject ("channel");
  If (channel! = null) {}
  JSONArray points = channel.getJSONArray("item");
  If (items! = null) {}
  for (int i = 0; i)< items.length();="" i++)="">
  JSONObject point = items.getJSONObject (i);
  this.imageURLs [i] = item.getString ("image");
  }
  }
  }
  }
  } catch (Exception e) {}
  e.printStackTrace ();
  }
  }

  I think that the problem lies in this method.

  public BitmapField getImage (String url) throws Exception {}
  InputStream inputStream = Connector.openInputStream (url) (InputStream);
  Bitmap image = null;
  BitmapField bf = null;
  try {}
  ByteArrayOutputStream Baos = new ByteArrayOutputStream();
  int ch;
  While ((ch = inputStream.read ())! = - 1) {}
  Baos.Write (ch);
  }
  Byte [] imageData = baos.toByteArray ();
  Image = Bitmap.createBitmapFromBytes (imageData, 0, imageData.length, 1);
  BF = new BitmapField (image);
  } {Finally
  If (inputStream! = null)
  inputStream.close ();
  }
  return (bf == null? null: bf);
  }

  public String [] getImageURLs() {}
  Return this.imageURLs;
  }

  }

  Finally my fatal mistake was in archive JSON, I change the URL of the images of http://localhost/image.jpg to
  http://user-xxx/image.jpg (MDS - CS available in http://localhost URL: 8080 /), and now it works!

  Ted and arkadyz, your suggestions have been very helpful for me, thank you very much!

• Huawei P9 - I have many issues with getting my pictures from the phone to my Imac

  Huawei P9 - I have many issues with getting my pictures from the phone to iphoto on my Mac.

  Before the summer I bought a Huawei P9 phone, I can easily see the photos on the phone - I can't just them on my mac.  When I connect via a USB cable, it refuses my permissions.

  I try to use my Google account to view on the Mac and move the iPhoto - I can't work either! I can see them, I can't move them!

  I'm pulling my hair out and I have enough to do with! Help, please...

  Jim Hosking

  You need the phone provider support - there is a problem with the way their phone works and how to use it and has nothing to do with the Photos or iPhoto - if pictures is consistent with standards of good Photos and iPhoto won't work with it

  You may need special third party software for your phone load in Photos or iPhoto

• How to quickly get 100 + photos from iPhone in pictures on iMac with the download speed very low broadband?

  Hi all

  I have an iPhone 6 Plus running iOS 9.3.1 and a retina iMac running OSX El Capitan 10.1.4.  I use iCloud photo library and I like the idea of having all the pictures synced across all devices.  This works well for one or two odd photos I take here and there.

  I have just been on vacation and taken 100 + photos with my iPhone and want to create an album of photo printed on my iMac, but the problem I am facing is that it takes so long to get the pictures on pictures on my iMac.

  My download speed high speed is very low - on 0.3Mbit / s, so the photos are always download to iCloud from my iPhone now, and I guess it will be another day or two to complete.

  Is it possible to get the photos from my iPhone to the iMac more quickly without creating duplicates or spoil my library?

  It's so frustrating to have to wait 5 days after her return from vacation before you can start making a photo album.

  Thanks for any help,

  Kind regards

  Ben

  You can connect the phone with USB and import or use iTunes sync or Capture of Image - this can cause a problem with duplicates

  And of course, you can stop by a store StarBucks, Apple (or other WiFi hotspot with good service) and complete quickly

• Is the another way to get the download from the support section

  Is there another way to get the download from the support section?

  Because the download speed is very slow. For example, in the new version of the value-added packaging and its 116 MB big need. A normal download time would be approximately 5-10 minutes. But when I download from Toshiba I need 2 to 6 hours. Not good for a company that manufactures laptops and high-performance computers.

  And the worst thing is that the connection is reset after a few hours... so I'll never get the update.

  Does anyone know help?

  Gruss
  Thomas

  Unfortunately, he has no other way to get the Toshiba drivers from the European pilot of Toshiba page.
  You are right at this moment that the file transfer is too long.
  I get about 10-19KO/s. That s is really very slow.
  Maybe the server is overloaded who knows I hope this will be resolved in the next time.

• How to get the string (specified by row and column) of txt file with labview

  Hello world

  How to get the string (specified by row and column) of txt file with labview

  THX

  As far as I know, a text file has no column.  Be more specific.  Do you mean something like the 5th word on line 4, where the words are separated by a space, and lines are separated by a newline character?  You can read from the spreadsheet String function and set the delimiter to a space.  This will produce a 2D channels table.  Then use the table to index and give the line number and column number.
