Yes you can use session value

You either need to buy a book or use Google. That is a very basic question.

ASP.NET is broken on my machine

Help,
Something happened and IIS has decided that it can no longer process ASP.NET pages. Instead, it just sends the text of the aspx page to the browser. This is on XP Pro SP2 running a solution built in Visual Studio 2005. The virtual directory in question has its .NET version set to the 2.0 framework. How do I fix this?

Cool. Thank you. That fixed all but one of them. And that one is probably installed improperly.

How to renew the value stored in Cache (Asp.net 1.1)

Hi guys,

I try to use Cache to store email's content which is used frequently throughout whole Web application,

The email was designed to put into a htm file, everytime when the application send email the system will read from the htm file, so the Cache is going to reduce some of IO overhead.

Cache("LINKASCHOOLEMAIL") = "emaill content"

But the problem is if I want to change the content of the email, the changes won't be reflected to cache until I reboot IIS (I can't do in this way because there are several Web applications in that IIS).

So is it any ways to resolve my problem?

Many thanks

What happens if you just write:
cache ("key") = "New email content"

Why would you need to restart iis?

because only when IIS is restarted, the cache can be emptied. The reason I want to renew the cache is I want the changes on email being able to be reflect to cache.

'Save email to cache<br />
      If Cache("LINKASCHOOLEMAIL") Is Nothing Then<br />
          Cache("LINKASCHOOLEMAIL") = "Read email from file"<br />
      End If<br />

Many thanks

I think im missing something
I dont get it
Why cant you just change the value of a cache element??

Doesnt 1.1 have this method?

Cache.Remove("Key")

Thanks Alexei,

Image that when I tried to deploy another version of application, which the email content(physical file) used by application has been updated, but the code still reads old value from cache instend of the new email file because cache("key") is not Nothing.

Im not sure if you can use this in 1.1

Take a look at CacheDependency
Add you email file as a cachedependency
Ass soon as you change that file, the cache item will be removed from the cache

When saving some special chars in SQL one needs to use a nvarchar instead of varchar datatype

There must be some datatype in mysql that can hold unicode chars

Dear All

I have a dropdownlist called ddlProduct (it will be fill by productName from product table)

I have two button called btnADD, btnFinish

First time : when you click the btnAdd then will fill a grid view called gvProduct (without adding data into database)
Second time: when you click the btnAdd then it will fill a grid view called gvProduct (without adding data into database)
trird time...........
.
.
.

Last Time

Now I will click btnFinish
when i click btnFinish then it will insert all data into OrderDetails (database table)

The project I want to do is simillar to OrderPlacement like Customer can select Product name from the DropDownList when customer click Add button
then it will shows on the right panel (customer will add more that 5 product) what he added into his basket including price

When he click submit then all data will be added into database and order will be placed

Any instructions will be really helpful

Thanks in advace
