• [Oracle 8i] How to convert a string (timestamp) in a date?

  I find it difficult to know how to convert a string to a date time stamp (or possibly several).
  
  The timestamp is 20 positions, character (NOT NULL, CHAR (20))
  in the format: YYYYMMDDHHMMSSUUUUUU
  where Y = year, M = month, D = day, M = Minutes, S = seconds and U = microseconds
  
  The reason why I want to convert it is so that I can compare a timestamp to each other (that is, I want to be able to find the MIN (timestamp), MAX (timestamp) and make comparisons of inequality).
  
  Is this possible?
  
  Thanks in advance for the help on this!

  Hello

  As Damorgan said, if all you want to do is find which is the earlier or later, then you can just compare the strings: they are in a format where it works.

  If you need to do other things, such as compare to today date or see the difference between two of your lines of days, you will need to convert it to date. (He has no reason to convert them to numbers).

  A new TIMESTAMP data type, which manages the fractions of a second, was introduced in Oracle 9.
  Since you use Oracle 8 (depending on your subject line), or it must be
  (1) ignores the microseconds, or
  (2) use a separate column for microseconds.

  Whatever it is, use TO_DATE to convert the first 14 characters in DATE:

  TO_DATE ( SUBSTR (txt, 1, 14)
          , 'YYYYMMDDHH24MISS'
          )
  

  where txt is your column of type CHAR.
  To convert microseconds to a number (between 0 and 999999):

  TO_NUMBER (SUBSTR (txt, 15))

• How to convert java.sql.ResultSet to intradoc.data.DataResultSet

  I used a MS jdbc driver to perform a query and got a java.sql.ResultSet.
  Now when I try this

  ResultSet rs = stmt.executeQuery (sqlString);
  Drs.Copy ((intradoc. (Data.ResultSet) rs);
  
  I get an error "ClassCastException.
  But they compile even without the cast.
  
  I also tried this:
  
  {while (RS. Next())}
  trace ("CPC" + rs.getString (1));
  String s = rs.getString (1);
  Vector v = new Vector < String > < String > ();
  v.Add (s);

  and I get an error

  Is there a way to do it (or something)? Y at - it the javadoc for intradoc.data.DataResultSet?

  If this does not work, you can always try something like this

  public static DataResultSet toDataResultSet(
       final java.sql.ResultSet p_resultset,

  ) throws SQLException {
  
       final ResultSetMetaData rsmd = p_resultset.getMetaData();

       final int[] columnTypes = new int[ columnCount ];
       for ( int i = 0 ; i < columnCount ; i++ ) {

            columnTypes[ i ] = rsmd.getColumnType( i + 1 );

• How to convert the object Bitmap to byteArray.

  Hi all

  I had a problem in the conversion of the bitmap object to. BMP file.

  (Real need: capture the screen shot and convert that turned to the screen.) BMP image and I have to keep this image in the SCARD

  I shouldn't use any PNGEncodedImage or JPEGEncodedImage )

  I capture the screen shot using the

  Bitmap BM = new Bitmap (width, height);

  Display.screenshot (WB);

  to get the data from [] bytes of this bitmap object that I use

  Byte [] _bytes = getBytesFromBitmap (bitmap);

  public byte [] getBytesFromBitmap (Bitmap bmp) {}
  try {}
  int height = bmp.getHeight ();
  int width = bmp.getWidth ();
  int [] rgbdata = new int [width * height];
  ByteArrayOutputStream Bos = new ByteArrayOutputStream();
  DataOutputStream back = new DataOutputStream (bos);
  Graphics g = new Graphics (bmp);
  bmp.getARGB(rgbdata,0,width,0,0,width,height);
  for (int i = 0; i)< rgbdata.length="" ;="" i++)="">
  If (rgbdata [i]! = - 1) {}
  dos.writeInt (i);
  back. Flush();
  //l++;
  }
  }
  Bos.Flush ();
  Return bos.toByteArray ();
  }
  catch (Exception ex) {}
  Dialog.Alert ("getBytesFromBitmap:" + ex.toString ());
  Returns a null value.
  }

  If I use this byte array in the Sub statement I get the "IllegalArgumentException".

  BMPEncodedImage.createEncodedImage (_bytes, 0, _bytes .length);

  all can help me how I can get the byte [] data from the bitmap object?

• Convert byte [] to bitmap

  How convert byte [] bitmap and convert bitmap to byte [] image and when to get the image of the server back to a string how to parse this string for byte [] exmple in android it parse like that

  Thanks in advance

  Hello

  You can use the method createBitmapFromBytes of the Bitmap class to convert an array of bytes to a Bitmap image. If you know that the image will be in PNG format you can even use createBitmapFromPNG

• How to convert the Bitmap Image in BlackBerry

  Hello

  In my application, I get the picture from the server. Now, I want to convert this Bitmap Image to display on the screen. For this I use below codes. But it doesn't give me the same image does not mean with the clarity and the exact size. He's smaller than the picture.

  I used the codes below:

  private Bitmap getBitmapFromImg(Image img) {

          try {
              Logger.out(TAG, "It is inside the the image conversion        " +img);
              Image image = Image.createImage(img);
              byte[] data = BMPGenerator.encodeBMP(image);
              Logger.out(TAG, "It is inside the the image conversion---333333333"+data);
              bmp = Bitmap.createBitmapFromBytes(data, 0, data.length, 1);

  Where an error in my code? Is there another way to do the same thing?

  Why you want to use a bmp image?
  You can just use png, jpg or whatever of the original image is.

• Don't know how to read the results of netstat EI s list? If I received 860592506 bytes sent from 43421482 how to convert MB? And does this mean byte received?

  Don't know how to read the results of netstat EI s list? If I received 860592506 bytes sent from 43421482 how to convert MB? And does this mean byte received?

  Hello

  This shows the total number of bytes transmitted and received via the Ethernet card. This is the total of the amount of use up to this day.

  This includes all the Web sites you have visited and emails you sent, etc..

  You can calculate using one of the following methods:

  Method 1:

  860592506 / 1048576 = 820,72 MB

  Method 2:

  Multiply 860592506 with 9.53674316 * 10 ^-7 that will give us the result in mega bytes.

  860592506 bytes = 820 MB 9MB not, accept my apology for the miscalculation.
  Similarly 43421482 acroos = 40MB
