View 1 RepliesI tried this link to generate verification Image [URL] ..... It works fine.
But I'd like to put a button in page for regenerating captcha for example. When the image was unreadable for user.
So I put an updatepanel in page and this is my code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<tr> <td colspan="2">
<asp:Image ID="imCaptcha" ImageUrl="~/Captcha.ashx" runat="server" />
[Code] .....
Although the image changes but the whole page is refreshed. Whether this is due to incompatibilities httphandler and updatepanel?
I am using the ASPNET_Captcha control for my login page. It works fine. However when i implement the forms authentication, the catcha image does not appear.

I have a web form that will send a message fine to every email address other than gmail (this one I know for sure) the message is " Delivery to the following recipients failed. " I know this email works since it is mine. I have my own e-mail server and when I send to the same gmail account the message goes through fine (using the same e-mail address in for form and in the e-mail client). Is there some coding I need to add to prevent this form message from being blocked?

Sometimes I would like to be able to update during day time my ASP .Net application. I noticed that quite often updating DAL's (.xsd files) that are in used will block my application (and users). The only way, I found to recover, is to restart IIS but my users do not like it.
Is there some more clean way to update an online server without disrupting the users ?
Could I identified the DAL which are in used and the users using them, so that I could somehow disconnect only these users (My application uses Windows authentication).

I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box

XP Pro,aspnet 2, IIS, Oracle I have a primary webpage that displays a tab and some summary data. The tab uses an iframe and the summary data is loaded by an async WebMethod call back to C#. The iframe page takes a short while to load depending on how much data is in there (sometimes upto 20 seconds?). The WebMethod call, or at least the content of it, is very fast. BUT, the WebMethod call won't return until basically the iframe has finished loading.
I've verified through Fiddler that the browser is initiating both requests at basically the same time. It's initiating the iframe call first followed immediately by the WebMethod call within the same second. My understanding is that browsers are limited to only two calls at once.
If I set a breakpoint at the end of my WebMethod call (even commenting out ALL it's guts so it just returns an empty string), that breakpoint won't fire until the aspnet page serving up the iframe has finished. Using threads window, I see both calls at the server. I just don't understand why the server won't actually run the Webmethod call until the first call has finished. I've searched the code looking Monitor.Enter, lock, etc to make sure nobody has inserted any other type of blocking code and I can't find anything. I've basically emptied out the WebMethod call and it just returns a string, but no matter what I do, it just won't return as fast as it can. If I comment out the iframe, then the WebMethod call returns within 2 seconds. With the iframe, it "looks" like the the webmethod call won't return until the iframe has finished.
1) Does aspnet only process one request per aspnet session id? Is it FIFO? I figured the webserver would just process requests and return each request as fast as it can.
2) What else can I do to get that summary data to return faster (but not actually loading and putting the data into the very first primary page) ?
I am working on a website that draws fractals on the screen. It was my intention that with a right mouse click the picture could be saved to the visitor's computer. But that I get an error message "filetype blocked".The file is called test.jpg and is drawn to the screen as a bitmap. Could anybody tell me how to 'unblock' the right mouse click so that a visitor can save a picture he or she likes?Maybe it would be possible to let people download the image? But how would that work?
