What exactly do you mean by "to clear" in this case?
To clear a string, you can replace it by string.Empty or null. To clear a numeric value, you can replace it by a zero value.
If you want to remove the key from the session variables collection, use the Session.Remove method.

Hello!
I have a major problem and I hope you can help me.
I have a multipart/form-data where I am browsing a picture file and then submitting it to upload.asp file. My animated progress bar is not getting displayed in upload.asp file because server is trying to complete the asp codes first and then it is displaying the html content.
How can I show an animated image or a text message in the upload.asp file during uploading process?
Thank You!
Bedri.

Hello
I think what you need is to flush the response object, using Response.Flush() after adding the animated stuff. This will output the html to the browser, while you can continue to do more processing on the server side.

Hello,
How do you test if the web service is available? Is this simply doing a
try {...} catch(System.Net.WebException) {...)
in every block of code where I try to access the web service?
Thank you for your help,

Hi,
Do you want to test whether the webservice is available or to know whether the available webservice is running??
When you want to test whether the avilable webservice is running:
1) It will throw a runtime exception as soon as you instantiate the Websevice in your implementation page.
When you want to test whether the webservice is available:
1) It will not allow to connect to the particular URL if it is not avaialbel from the WebReference dialog box.
Regards

Hi guys,
I would like to inquire how to get the webpage/url address in real time from the back button. As we can see, when we push (down) pull down button in the back button, we can view the previous webpage visited. Is there a way to retrieve the url address in the back button without clicking on a link or a button using javascript?
your help would really be much appreciated.

The window.history property is an array of URL strings which reflect the entries in the History object
the previous property contains the complete URL of the previous element in the History list, and is the equivalent of the URL the user would go to if they selected Back in the Go menu.
Syntax: history.previous

There are also many web hosts tha wil give you free web space, however you wont get a .com address but a very long address, more like a page inside a web site. Go to your search engine Google.com and start looking. These web site also give step by step instructions on deploying your web site

I don't think you can. The quota for otherwise useless websites has been met (and exceeded), so web hosts are taking proactive steps to prevent the exponential increase of idiot wanna-be web masters.

Hi Guys,
We have an app with 3 tiers a data,bussiness and presentation layer(asp.net 2.0). Any exceptions thrown by the data layer are caught and logged by the business layer, which then throws a custom exception to the ui which displays a simple message to the user which does not divulge any sensitive information to the user.it is unwanted to have a try catch block for every method in the business layer which is growing considerably so i want to catch the unhandled exception in one generic catch for the business layer (see below), this method would log the exception,send out notifications and create new custom exception which would be thrown to the presentation layer. All classes in the business layer would subclass a base class which would have the code that assigns the unhandled exception delegate in its constructor. the code works in an console application but it does'nt work in a Class Library Project which is what our bussiness tier is. The Application_UnhandledException is called if it's in console,or normal windows app but i need this method to be called in a class library project. Any assistance is greatly appreciated,it become very urgent to get this working. Thanks guys
e.g
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
public static void Application_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
if (e.ExceptionObject is System.Exception)
{
//TODO LOGGING CODE,notifications ETC
}
}
The Global.asax file in the presentation layer would catch the final custom exception in the application error method. The message the user would see is simple e.g An Error Occured. The Error was logged and the support team has been emailed details of the error, please contact you admnistrator for further assistance.So The ErrorPage.aspx would use the innerexception of the exception object (CustomException) and display the simple message contained in it
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
Exception exc = Server.GetLastError();
Session.Add("LastError",exc);
Response.Redirect(@"~\ErrorPage.aspx", true);
}

The Application_UnhandledException will be called at application level if you don't catch the exception. As you catch it in the presentation layer, it's never unhandled.
You can't make the Application_UnhandledException work in a library, as a library is not an application.

Do you want to match it for validation, or to extract data? Something like this?
"^(\d+(-\d+)?)(,(\d+(-\d+)?))*$"
