View 3 RepliesI want to read from database where I've stored a image in binary field and display a image.
while (reader.Read())
{
byte[] imgarr = (byte[])reader["file"];
Stream s = new MemoryStream(imgarr);
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
Graphics g = Graphics.FromImage(image);
g.DrawImage(image, new Point(400, 10));
image.Save(Response.OutputStream, ImageFormat.Jpeg);
g.Dispose();
image.Dispose();
}
con.Close();
This piece of code doesn't work:
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?

View 1 RepliesI have stored images in sql in the form of binary data. Now I want to convert it into image for displaying purpose.
I am doing like this
BLLogin blg = new BLLogin();
Is there such a thing? So for eample, on my image load I have the following hooked up to a table where "Image" is a binary image set of data.
protected void Image1_Load1(object sender, EventArgs e)
{
myent logo = new myent();
var query = (from p in logo.tblLogoes
where p.Id == id && p.Id2 == id2
select p.Image).First();
return query.
}
What do I need to return here to populate the image? I have funny feeling, it's not going to be as simple as that.

I want to extract an image from a third party Sybase table which has binary data in it.
To store images they use the following query:

Not sure if this issue should be posed here, but i try anyway:I have a webpage with a button, button click the webpage will write an image (in binary) to the response object, resulting the user can open or save an image.
Code:
response.ClearHeaders();
response.ClearContent();
response.AddHeader("Content-Disposition", "attachment; filename=abc.jpg");
response.AddHeader("Content-Length", binaryImageFile.Length.ToString());
response.BinaryWrite(binaryImageFile);
response.Flush();
response.Close();

I need to display a binary image from database in RDLC report in a table.
View 2 RepliesThe thinking behind the question is that my image current reads it's data from a custom httphandler that gets the image from the database. I want to be able to use a file upload control to "post" a replacement file back to a "write" handler, updating the database. Then I can refresh my image using javascript to the original "read" handler. Is this possible?
I currently have a standard postback model upload process which puts the image into the database and a custom handler to read it back. What I want to know, is can you create a custom http handler to perform the upload so I could asynchronously call the upload handler then refresh the image src to pull it back from the database. At the moment I am using the IFrame approach to make it appear asynchronous, I just want to know the best practice really
