Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?

View 1 RepliesI am using an application from a book for a shopping application , to adapt for my own learning, but there seems to be a problem with the shopping cart page. This is a section I have not changed as there is no need to but there is an error. In the code behind the only thing new is the namespace:
namespace OIClothing
{
public partial class Cart : System.Web.UI.Page

ShoppingCart cart; // it doesn't like this, giving the debug message the type or namespace 'Shopping Cart" could not be found

if (!IsPostBack)
GridView1.DataBind();
btnCheckOut.Enabled = (cart.Count > 0);
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
cart.DeleteItem(e.RowIndex);
GridView1.DataBind();
}
but when running the page, this error is given: CS1061: 'ASP.cart_aspx' does not contain a definition for 'GridView1_RowDeleting' and no extension method 'GridView1_RowDeleting' accepting a first argument of type 'ASP.cart_aspx' could be found (are you missing a using directive or an assembly reference?)
I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.

And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
We have an old asp application that instantiates a .NET com visible class. In this class, we do some serialization to store our object in the session.
When I call the following line of code in my test class, it works fine.
var cereal = new XmlSerializer(couponApplicator.GetType());
However, when it gets called in the website and I am debugging, it throws the following error:
{"Cannot execute a program. The command being executed was "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe" /noconfig /fullpaths @"C:\WINDOWS\TEMP\rwot-yx9.cmdline"."} System.SystemException {System.Runtime.InteropServices.ExternalException}
I thought maybe it was permissions related so I tried giving 'EVERYONE' full control to the windows/microsoft.net folder as well as the windows/temp folder. For reference, I am running this on a Windows XP machine.

I have implemented the following functionality that connects to webservice and downloads a favicon from a given site and saves it to a byte[] which I store in our database. I now want to set it up so that it saves the icon to the disk. However I am getting a "Parameter is not valid" when I try and create the image from the byte[].My code is as follows..
stream.Write(imageByteArray, 0, imageByteArray.Length);
Image i = Image.FromStream(stream); // EXCEPTION HAPPENS HERE.
i.Save(@"C: mp" + filename + ".ico");
The exception occurs on the middle line. This code works perfectly 9 times out of ten, but for some favicons, even thought the icon is a valid image (or at least it appears to be and it shows in the browser when point at it) I get this exception. Does anyone have any ideas? I am pulling my hair out here!

View 5 Repliesi would very much like to capture certain dal/bll exceptions in my page_error code and turn them into validation errors so they should show up in the validationsummarythis is the code im trying now
[Code]....
the logic is simply to catch only exceptions of type ArgumentException, otherwise it should bubble up (to global.asax handling)what hapens is that after this code block runs, the exception still exists in the system, so it always bubbles up to the global.asaxit there any way to tell asp.net that "its ok, i took care of the exception, just continue with the page"?i tried server.clearerror and context.clearerror but these methods stop the whole page and return a blank empty pagethank you all for your time and patiencep.s. if u have any other ideas 4 improving this code,
