This is ASP.NET Forum. There is nothing to do with it in ASP.NET. You should ask it in C# Forum. Smile | :)

Hi all,

Does anyone know of how to (or point me to some information on how to) send and email using X.509 PKI with attachments. There are a lot of posts around the Internet on using X.509 without attachments but it fails for emails with attachments.

I would like to do this myself with native C# code and not use a third party product if possible.

Thanks,
Maurice

Hi all.

So here is my problem. The application is hosted in Windows Server 2008 with IIS7.

I have a button (from Silverlight page) that calls a new webpage (asp.net page, ext .aspx) that contains Response.OutputStream.Write(blahblahblah) which then should prompt a download box to allow user to save an image.

Now the page basically creates a stream and then is supposed to output the stream to the user using Response.Outputstream.Write.

Then the user is supposed to be prompted to open or save the document. This works fine in Firefox but it does not work with IE7 or 8

Also this exact same code works with IIS6 on a Windows 2003 server.

So the only differences is the IIS6 and Windows 2003 Server to IIS7 and Windows 2008 Server.

And what happens is when I clicked the button, the page did pop up but disappear 1-2 seconds later without prompting the download box to the user.

Here is the code that launches for Reference

//e.g file = 123424_43535.jpeg
FileInfo myFile = new FileInfo(Server.MapPath("mapImage/") + file;
using(var fs = myFile.Open(FileMode.Open, FileAccess.Read))
{
byte[] buffer;
int read;
buffer = new byte[(int)fs.Length];

Response.AddHeader("Content-Disposition", "attachment;filename=" + file);
Response.ContentType = "application/x-force-download";
Response.AddHeader("Connection", "Keep-Alive");
Response.AddHeader("Content-Length", fs.Length.ToString());
while((read = fs.Read(buffer, 0, buffer.Length)) > 0)
{
this.Response.OutputStream.Write(buffer, 0, read);
}
}
Response.End();

I have tried to replace Response.AddHeader with Response.AppendHeader, however the result is still the same.
Also, I have tried to replace the Response.ContentType with application/octet-stream and image/jpeg, I also faced the same result.

Is there any setting/modification on server/code that I need to look on?

This problem has bugged me for a long period and a quick reply/solution will be very much appreciated.

Thanks and have a nice day.

Regards,
Kent

Hi,
In my gridview i have added the following field to view (summary) of a particular order number.
<asp:buttonfield buttontype="Link" runat="server" text="View" commandname="View">
The summary is displayed in the same page. I have used rowcommand event of gridview for the control.
My code works well but i want to change the text of control from view to *view once it is clicked so that one recognizes the order that is being viewed.
I tried searching but am not sure as wat to search. Please provide guidence in this regards.

Thankyou

Hi
One of my project i need a generic parser. The requirement is as follows

1. Should be a Fast forward only parsing
2. Child Nodes of a given nodes need to be parsed. (Different XML formats are supported)
eg : Root1\Root2\Root
Child1\Child2\Child
3. Traversing through each Sub nodes in selected Child nodes
and store value into database

My Question is XPath supported in Fast Forward only parsing. i would to know about the best ways to solve this issue with a better performance.

Cheers
