I built an app in IronSpeed Designer that works fine when I am just looking at it using localhost.  It's a table that has columns, one of which is a button.  When you click on the button, it looks in the db for a file that you have uploaded, and downloads the file for viewing.

Everything is working fine when I am on the machine that is hosting it and I look at it using localhost.

It even looks fine when I have it inside an IFrame.  I can do all of the functionality except the downloading.  The event code is in the clicked event of the button.  As I said, it works fine when I am outside the IFrame.

Any ideas?  This is pretty much it as far as what I have to do before I deploy this thing.


 

public override void Initial_Click(Object sender, EventArgs args) 
{
    try 
    {
        DbUtils.StartTransaction();

        // Get the record.
        LegalContractSubmitRecord  rec;   
        rec = this.GetRecord();
        if (!(rec == null))
        {	
        	this.Page.Response.Write("Inside rec !=null");
            // Get the name of the attachment.
            string filename = rec.initialFileName;
            byte[] contents = rec.initialFile;
            
            // Store the contents of attachment temporarily in a file.
            // Delete the temporary file if it exists already.
            if (System.IO.File.Exists(filename))
            {
                System.IO.File.Delete(filename);
            }

            // Create the temporary file and store contents.
            System.IO.FileStream fs;
            fs = new System.IO.FileStream(filename, System.IO.FileMode.CreateNew);
            System.IO.BinaryWriter bw;
            bw = new System.IO.BinaryWriter(fs);
            bw.Write(contents);
            bw.Flush();
            bw.Close();
            fs.Close();

            // Set up download parameters.
            this.Page.Response.ContentType = "APPLICATION/OCTET-STREAM";
            string disHeader;
            disHeader = "Attachment; Filename=\"" + filename + "\"";
            this.Page.Response.AppendHeader("Content-Disposition", disHeader);
            System.IO.FileInfo fileToDownload;
            fileToDownload = new System.IO.FileInfo(filename);
            this.Page.Response.Flush();
            this.Page.Response.WriteFile(fileToDownload.FullName);
            this.Page.Response.End();
        }
    }
    catch (Exception ex)
    {
        DbUtils.RollBackTransaction();
        
        // Report the error message to the user.
        BaseClasses.Utils.MiscUtils.RegisterJScriptAlert(this, "UNIQUE_SCRIPTKEY", "There is no file loaded.  Edit the record and upload a file.");
    }
    finally
    {
        DbUtils.EndTransaction();
    }
}
