Hi Bassem
if you get your data in a dataset using an Using an sqlDataAdapter , then
every thing will be returned as object . if you know that the field you
have in hand is an image then you can cast it to the appropriate type
These links give examples that would help


hope you find what you need in these examples

Thanks Mohamoss....
I read so much in this links and get more ideas.
I implement code to save photo and succeed in that.

The code I Implement in C#. [Using OleDbDataAdapter]

Global field to hold the path of the photo: GSPathImage
The function used to get the path of the photo:
private void EmployeePhoto_Click(object sender, System.EventArgs e)
System.Windows.Forms.OpenFileDialog ofd = new OpenFileDialog();
ofd.Title = "Employee Photo";
ofd.Filter = "Bitmap (*.BMP;*.DIB;*.)|*.BMP;*.DIB|JPEG
(*.JPG;*.JPEG;*.JPE;*.JFIF)|*.JPG;*.JPEG;*.JPE;*.J FIF|All files
(*.*)|*.*" ;
pBEmpPhoto.Image = new Bitmap(ofd.FileName) ;
GSPathImage = ofd.FileName ;
GSPathImage = GSPathImage == null ? "" : GSPathImage ;
byte[] photo = GSPathImage == "" ? new byte[0]: GetPhoto(GSPathImage) ;

OleDbParameter oledbParam = new OleDbParameter("@ImagEmployee"
,OleDbType.VarBinary,photo.Length,ParameterDirecti on.Input,true,0,0,null
, DataRowVersion.Current ,photo);


Example to add values for Employee and his photo:

oleDbDataAdapter1.InsertCommand.CommandText =
"INSERT INTO EmployeeSalary(EmployeeName , ImagEmployee )"+
"VALUES ('"+lsNewEmpName+"' , '@ImagEmployee' )";


Till now everything going ok and no exception.

When retrieving the photo I get exception.
The code of the retrieving:

string EmployeeValue = txtBEmployeeName.Text.Trim();
string myOleDBstring = "SELECT EmployeeName , ImagEmployee FROM
EmployeeSalary WHERE EmployeeName = '"+ EmployeeValue +"'";
DataSet dsTest = new DataSet();
OleDbDataAdapter oledbTest = new OleDbDataAdapter(myOleDBstring
oledbTest.Fill(dsTest ,"EmployeeSalary");
int testrec = dsTest.Tables["EmployeeSalary"].Rows.Count;

if(testrec > 0 )
Byte[] byteBLOBData = new Byte[0];
byteBLOBData =
MemoryStream stmBLOBData = new MemoryStream(byteBLOBData);
pBEmpPhoto.Image = Image.FromStream(stmBLOBData);
And the exception is:
System.ArpumentException: Invalid parameter user.

Thanks for the help.
