I need to upload images from client to server as follows:1. Server is passing the client a file name 2. Client is checking file extensins to ensure it's an image then issues a __dopostback to the server. 3. Server uses the FileUpload control to save the image on the server.I have that all covered, but, if image is too large, the upload fails with the following error: 'System.Web.HttpException: Maximum request length exceeded.'Is there a way to check file size on the client (without the use of ActievX which also errors out), before it is passed back to the server?
Sample code will be greatly appreciated.

Hi to all,
I have some things that I want to know. I am right now using a free asp.net webhosting ("somee.com"). The problem is that when I am visiting a page, there's a tendency that values stored in my session variables are lost. Therefore, it causes an error when the requested page is loaded.
1. I am thinking of using sessionState mode="SqlServer". Will it solve my problem?
Actualy Im working on it but Im having problems when connecting to the sql database.
2. Is that a problem in the webhost?
3. Do free webhosting sites provide allow session state in the sql server?. Because ive tried it locally into my computer and error say's i should intall the ASP.NET Session State SQL Server version 2.0 or above.

I am creating a simple shopping cart using a datatable that is passed into a session object. I have a small mini cart that displays the total number of items in the cart as well as the running total - this is displayed in a web control. When the web control starts up I run a try/catch to see if the session object exists, if it doesn't I create the datatable for the cart and store it in the session. I then have a datalist control that contains all the information for my products including an "add to cart" button. When the page loads everything looks fine. If I click on an "add to cart" button nothing happens to the session information. If I click on it again, the session information updates - displaying only one item is in the cart and then counts up correctly there after. Additionally, after adding an item, if I select a different item in the list, the same issue occurs. I am not sure why this is happeing, if anyone can give me an idea I would appreciate it.

What are the issues (if any) of setting sessions to expire after an extended period of time as in 4-8 hours? I'm building an intranet app which is designed so that users will access it once in the morning and then leave it used, possibly, for hours at a time. I'm assuming that there aren't too many since
1) we're running it on a intranet 2) sessions are soley to retain state between requests3) its not like a connection to the DB where you can conceivable run out

Having a very wierd problem. I have an application that uses Crystal Reports and it uses what I have found to be a common scenario (I am not a CR expert in any way). I have an ASPX page that gathers options for the report, and then it goes and gets the data and if there is some, a button appears for them to launch the report. On clicking that button, the code sets some values in the HttpResponse.Context area, then performs a Server.Transfer to another ASPX page that is our Report Template. This page contains the CR stuff and it generates a PDF version of the report. It then does the following code:
With HttpContext.Current.Response .ClearContent() .ClearHeaders() .ContentType = "application/pdf" .AddHeader("Content-Disposition", "inline; filename=Report.pdf") .BinaryWrite(s.ToArray) .End() E

Hi Everyone, I need to detect the size of the user's screen for mobile devices (especially the BlackBerry). I've read a lot of pages that seem to refer me to the Request.Browser object, but I'm finding that this object doesn't have the correct values. For example, I have a BlackBerry and when I use the Request.Browser to get the screen size, it tells me it is 640x480. Well, I know it's not that big since an image of 300px wide just barely fits. Also, when I run on my desktop browser, it also says my screen is 640x480. I can assure you, it is not 640x480! ha!
