Question
Binary field in SQL Server
Hi,
I'm using CRecordset to open a SQL server table through ODBC. I have encountered a problem with a binary field. The binary data retrieved will always be different from what I have added to the table. I have added the CRecordset using the "insert new class" and the variable type of the field is CByteArray. Is there anything wrong with this? The codes generate in the DoFieldExchange function is :
RFX_Binary(pFX, _T("[Data]"), m_Data);
Thanks.

Hi,
I finally get back the correct data.
Previous when adding of new record to database, I have tried to :
m_Data.RemoveAll(); //clear all objects
m_Data.Add(1); //add until the max length(10)
.....
This does not work so I try with :
m_Data.SetSize(10);
m_Data[0] = 1;
..........
This works fine. Isn't adding and setting size the same as long as the final array size is 10?

>>RFX_Binary(pFX, _T("[Data]"), m_Data);
You don't have a max size.
Example:
RFX_Binary(pFX, _T("[Image]"), m_Image, 8000000);
