All,
How should we refresh the current aspx frame? I disabled caching using this
command on Page_Load():
Response.Cache. SetCacheability (HttpCacheabili ty.NoCache);
but it didn't help.
The problem is that this page shows the client Logo image, then asks to
upload a new one if required, finally it should show the uploaded picture.
The problem is that it doesn't. If I press F5, then I can see the updated
image, but if I didn't press F5, then I see the previous image.
The aspx page (frame) has the following code:
<asp:Image id="ImageLogo" style="Z-INDEX: 106; LEFT: 145px; POSITION:
absolute; TOP: 163px" runat="server" ImageUrl="Image r.aspx"
BorderColor="Li ghtBlue" BorderStyle="So lid" BorderWidth="1p x"></asp:Image>
When I trace in debugger I see that after uploading the child frame
mentioned in this control (ImageUrl="Imag er.aspx") is not calling. When I
press F5 to refresh the frame the child frame is called and refresh the
image.
How can we refresh the frame from C# to renew the image?

It is possible that images will cache, when named the same, even if the page
does not cache. It is one of those cute browser quirks. If the image has a
different name, you should not have a problem, unless your code is set to
make certain decisions prior to checking for the newer image.
You can set up the page to automatically refresh, using a meta tag perhaps,
but you still end up with the same issue if the image is being cached.

Gregory,
Wow, if this is a "feature" then in this case it's easier to generate the
control name on the fly using the current datetime, maybe it will make the
page cache useless. I think it's possible although takes a few lines of
code.
Thanks for this info, I was thinking that I'm crazy.

Hi,
I have a private website for 20 people that is similar to a web email client
like hotmail.
There are two frames, one on the left with links for "New", "History",
"Todays" and a frame on the right with a table for viewing the contents of
these messages. The left pane checks back with the server every few seconds
to see if any new messages need to be processed and updates count
accordingly.

Hi guys,
I want to refresh some pages every 2 seconds.
however, these html pages are not in my site, they could be any pages from
yahoo.com or msn.com.
I can create a page, which redirect to public internet html page, but how
can I do this in a loop?
do I need to write a console application to make it work?
thanks
