Old drag and drop code no longer works in windows 7

I have some code that allows me to drag and drop a hyperlink from a webpage onto a windows form, and it seperates the URL and the Title 开发者_如何学Pythonand puts them in two different text boxes.

This works on windows XP fine, but on windows 7 it no longer works. I'm not sure where the difference lies.

object data = e.Data.GetData("UniformResourceLocator");

data will always be null, but when i use

 string[] fmts = e.Data.GetFormats();

one of fmts will always be UniformResourceLocator, along with a bunch of other ones that I can never seem to get any data from. If anyone has an resources to point me to or something I would greatly appreciate it, this is really confusing for me.

Thanks.

UPDATE:added method code that used to work

  string hyperLinkUrl = null;
        string hyperLinkText = null;

            hyperLinkUrl = e.Data.GetData(typeof(string)) as string;
            // some browser deliver url and text
            // in UniformResourceLocator (Firebird)
            string[] tokens = null;
            if (hyperLinkUrl != null)
            {
               tokens = hyperLinkUrl.Split('\n');
            }
            if (tokens != null && tokens.Length > 1)
            {
                hyperLinkUrl = tokens[0];
                hyperLinkText = tokens[1];
            }
            // we have to read FILEGROUPDESCRIPTOR to get the text (IE)
            else
            {             

                System.IO.Stream ioStream =
                (System.IO.Stream)e.Data.GetData("FileGroupDescriptor");
                byte[] contents = new Byte[512];
                try
                {
                    ioStream.Read(contents, 0, 512);
                }
                catch (Exception x)
                {

                }    
                ioStream.Close();
                System.Text.StringBuilder sb = new System.Text.StringBuilder();
                //The magic number 76 is the size of that part of the
                //FILEGROUPDESCRIPTOR structure before
                // the filename starts - cribbed
                //from another usenet post.
                for (int i = 76; contents[i] != 0; i++)
                {
                    sb.Append((char)contents[i]);
                }
                if (!sb.ToString(sb.Length - 4, 4).ToLower().Equals(".url"))
                {
                    throw new Exception("filename does not end in '.url'");
                }
                hyperLinkText = sb.ToString(0, sb.Length - 4);
            }
            tbLinkTitle.Text = hyperLinkText;
            tbLinkAddress.Text = hyperLinkUrl;

drag and drop a hyperlink from a webpage

That page wouldn't be in a web browser running in low integrity (e.g. IE Protected Mode), would it? Drag-and-drop doesn't work across integrity levels.

• http://en.wikipedia.org/wiki/Mandatory_Integrity_Control

What happens if you use icacls to set your executable's integrity level to low as well? If drag-and-drop starts working, this was the problem.
