asp.net gif as progress bar

Question

hello everyone :-)

i have a button that runat="server" and i want to show a progress GIF while the send process is running.
i tried to do that with img="bla.gif" visible=false and true. it doesn't working.
then i tried to do that with 2 Threads that running together - doesn't working at all.

do you have any other suggestion for this case? pay attention that the button must run on server because it is an email sending.

thank you!!!
Ido.

Answer 1

I think you want once anybody have read email ,you will find notification.

I think you need to send a link with a mail to confirm,

otherwise its not possible ,because its not allow from gmail. 

Answer 2

There is no direct way to get the Mail read status from outside of the email box. However, there is a hack for this and refer the below link for more details.
