GDViewer Image to SQL Database

[rwebster]

I have an application that users scan a Drivers License into and Displays on screen using GDViewer. How do I go about getting that image saved into a Microsoft 2008r2 SQL Database.

Thanks

Does anyone have information on getting the image to any other Databases? Any help is better than nothing.

Thanks

Well you're going to have to put it into a byte array. SQL Server has a image variable you can use if you want, or varbinary(max). This probably isn't the forum for this, but I have this code handy. I could probably put in a few more usings in my code too, but here it is.

public static int InsertImage(byte[] imageData, byte[] imageThumbData, int userId, string fileName)
{
string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["arDBserver"].ConnectionString;

using (SqlConnection conn = new SqlConnection(connectionString))
{
string cmdText = @"INSERT INTO nd_images
(ImageData,ImageThumb,UploadDate,UserId,FileName)
VALUES(@ImageData,@imageThumbData,GETDATE(), @UserID,@FileName) SET @Identity = SCOPE_IDENTITY()";
SqlCommand cmd = new SqlCommand(cmdText, conn);

SqlParameter identityParam = new SqlParameter("@Identity", SqlDbType.Int, 0, "ImageID");
identityParam.Direction = ParameterDirection.Output;

cmd.Parameters.AddWithValue("@ImageData", imageData);
cmd.Parameters.AddWithValue("@imageThumbData", imageThumbData);
cmd.Parameters.AddWithValue("@FileName", fileName);
cmd.Parameters.AddWithValue("@UserID", userId);

cmd.Parameters.Add(identityParam);

conn.Open();
cmd.ExecuteNonQuery();

return (int)identityParam.Value;
}
}

If you want to insert into a varbinary(max) for a regular file that could be an image too or maybe a blob in other database, here is code for inserting a file:
public static int InsertFile(byte[] data, string description, int userId, string fileName)
{
string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["arDBserver"].ConnectionString;

using (SqlConnection conn = new SqlConnection(connectionString))
{
string cmdText = @"INSERT INTO nd_files
(fileName,data,description,userId)
VALUES(@fileName,@data,@description,@userId) SET @Identity = SCOPE_IDENTITY()";
SqlCommand cmd = new SqlCommand(cmdText, conn);



SqlParameter identityParam = new SqlParameter("@Identity", SqlDbType.Int, 0, "fileNo");
identityParam.Direction = ParameterDirection.Output;

cmd.Parameters.AddWithValue("@data", data);
cmd.Parameters.AddWithValue("@description", description);
cmd.Parameters.AddWithValue("@fileName", fileName);
cmd.Parameters.AddWithValue("@userId", userId);

cmd.Parameters.Add(identityParam);

conn.Open();
cmd.ExecuteNonQuery();

return (int)identityParam.Value;
}
}
