RE: [DUG]: Streaming Data to/from BLOBs

[Carl Reynolds]

Use TDataSet.CreateBlobStream to get a TBlobStream for a TBlobField; then you can use the methods of streams to transfer information as you need.  The help on CreateBlobStream and TBlobStream has examples.   Cheers, Carl   -----Original Message----- From: Colin R Dillicar [mailto:[EMAIL PROTECTED]] Sent: Sunday, 4 June 2000 12:47 PM To: Multiple recipients of list delphi Subject: Re: [DUG]: Streaming Data to/from BLOBs Hi, I need some help,   I am having difficulty passing information between a BLOB field in a database and an array in memory and would appreciate it if someone familiar with the process would provide me with some sample code.   The array I have is "Program Data", as follows :-   type        DataLocations  = record           Data  : array[1..6] of byte;         { Can I define the array as byte or should I pack two bytes into integers ?}       end;   var       ProgramData  :  array 1..200 of DataLocations;       When accessing any record in the database I need to get the data in its Blob field into Program Data, maybe modify it, then put it back when done with the record.     I believe I have to first Create then later Destroy the buffer, but don't really understand how this is done. I imagine it's pretty simple but its got me beat.     TIA        Colin
