Working with BLOB data

The following code fragment demonstrates how to use the ULColumn.GetByteChunk method to get BLOB data.

For more information, see GetByteChunk method.

' eMbedded Visual Basic
Dim offset As Integer
Dim nBytes As Integer
Dim chunk(1024) As Byte
ll = col.GetByteChunk( 0, chunk, 1024)
If nBytes <> 1024 Then
   ' only got nBytes bytes, expected 1024
Else
   ' have 1024 bytes
End if

// JScript
var offset;
var nBytes;
var chunk = new Array();
nBytes = col.GetByteChunk( 0, chunk, 1024);
if ( nBytes != 1024 ) {
  // only got nBytes bytes, expected 1024
} else {
  // have 1024 bytes
}
