"Bitmap Image is not valid" raised when displaying TDBImage

Hi guys,

I moved my paradox tables to SQL and I am trying to access the new Database using the same Application thru ODBC. I cannot access the bitmaps stored in the blob fields using the TDBimage controls.
An error raises: "Bitmap Image is not valid" for every record when a TDBimage refers to one of its fields.
On the other hand, if I paste an image on one of them, they work fine.
I´ve tried hard to look for a solution by myself, but It´s beyond my knowledge, so I´d appreciate some help.

How were the images stored in paradox (i.e., GIF, BMP,etc.). As I recall, default bitmap viewers (TImage or TDBImage) in Delphi only support windows bitmap and JPEG by default, you have to add extra code to support GIF, etc.
How did you move the tables and what datatype are you using bor the bitmap column?

I created an ADOCommand with run-time created parameters like that:

for k:=0 to table1.FieldCount-1 do
with AdoCommand1.Parameters.AddParameter do
case table1.Fields[k].DataType of
{... other stuffs...}

I use a SQL sentence like bellow:
Insert into <table> (field1,...,blobfield,...,fieldn) values (:field1, ...,:tblobparameter,...,:fieldn)

I am using "image" datatype for the table field
for the tblobfield.blobtype property I am using "ftblob"

Either I use an ADOTable with OLEDB or I use TTable with ODBC I get the message, then I suppose something wrong has occured during the moving of the tables.

I remeber this is a bug in some versions of the ODBC drivers that cause problems when moving blobs that are greater than 64K in length. Does this seem likely?

Most of the images where captured from a scanner. Some of them thru paint.

I'm sorry I didn´t answered it before. It took me some time to test the hipotesys of using other format than BMP in the tdbimage component. I was using an extended version of it which could accept JPG and GIF formats. It seems the extended version was prepared to deal with those format if they come from a paradox database, but not from MSSQL.
