Colin 'Blob has been modified' is a variation of the old familiar theme of 'Index out of Date'. It's basically the same problem - blobs are references in one database file to stuff in another database file - and the BDE has mechanisms in place to detect when the reference and the contents get out of synch. usually the problem happens on windows networks when some buffers get flushed and some don't. There has been a lot written about this problem. Take a look at Borland Tech document TI3342. There is a reference to it here http://community.borland.com/article/0,1410,15209,00.html Anyone who has done any nontrivial app using the BDE and Paradox tables has lost some sleep over this - you are in ample, if not good, company. <g> good luck ns -----Original Message----- From: Colin R Dillicar <[EMAIL PROTECTED]> To: Multiple recipients of list delphi <[EMAIL PROTECTED]> Date: Saturday, 30 September 2000 09:28 Subject: Re: [DUG]: BLOB Problem Hi all, Suggestions please, Some time ago I had occassion to ask for help in setting up a BLOB field in a Paradox database and transferring data to and from an area of memory set up as an array of byte. The transfer has been operating fine except that on a couple of occassions I have had an exception report :- Project (Whatever) raised exception class EDBE Engine Error with message 'BLOB has been modified' Process stopped. Use Step or Run to continue when attempting to run the program.I have established that the size of the array hasn't changed and I have temporarily fixed the problem by copying backup database files into the directory and carying on. This hasn't been too much of a hastle in the past but the database is growing and the problem now has to be fixed. Question - What might be causing this ? May be related ? - At compile time the compiler (Delphi III ) reports - Variable 'BStream' might not have been initialised. Question - What have I missed doing ?
