Question

I’ve been looking around and reading about handlers, but I don’t fully understand how to implement them for my situation.

I want display a screenshot from the user’s clipboard. I already have code that retrieves the image from the clipboard into a bitmap format. This is what I have:

var dataobj = new DataObject();
dataobj = (DataObject)Clipboard.GetDataObject();

System.Drawing.Image img = dataobj.GetData(DataFormats.Bitmap) as System.Drawing.Image;
original = (System.Drawing.Image)img.Clone();

img = resizeImage(img, new Size(670, 500));
String s = "c:/Temp/temp.png";
img.Save(s, ImageFormat.Png);
Image1.ImageUrl = s;
Image1.DataBind();

My problem was that I am not able to save the images to the hard disk.

My first question is will an image handler help me in this situation?

if it will, how do I modify that code and tie it into my image handler with this code:

public class getmyimage : IHttpHandler 
{
  public void ProcessRequest(HttpContext context)
  {
    HttpResponse r = context.Response;
    r.ContentType = "image/png";
    // Write the requested image
    r.WriteFile("temp.png");
  }

  public bool IsReusable
  {
    get { return false; }
  }
}

Hello handlers http allow customers to redirect or rewrite requests, format headers of requests for security reasons, or display a banner in some forums. but for your example i think you don’t need http handler
