Now i am in a condition, Where I am just displaying the month names and numbers. There is a small issue. I need to get month names instead of month numbers from Oracle.
here's my query
SELECT Count(*),EXTRACT (MONTH FROM DATE_CREATED),EXTRACT (YEAR FROM DATE_CREATED) FROM MyTable GROUP BY EXTRACT (YEAR FROM DATE_CREATED) ,EXTRACT (MONTH FROM DATE_CREATED)
And the result is 3 columns. Count, Month(Number) and year
something like this
3 10 2006
Please anyone help to convert the month number to month name in oracle or C#. Problem is I cannot use the data formatting functions as this is a single number appearing.
Thanks for any help!!!!!!!!!!!!!!!

You mean the ON DELETE SET NULL option in SQL 2005? I don't think there is an equivalent in Access. You should probably run an UPDATE query on your foreign key field before your DELETE query to set any values related to this picture to NULL.

Hi all,
my project is based on inserting and retrieving video files (type :MPEG)
I'm using ASP.NET2.0 and SQL SERVER 2005
my question is how can I insert video files in the database????
bleave in your self
|
|
|
|
|
This question has nothing to do with ASP.NET. The ASP.NET part would be 'how do I upload video files'. You realise that unless you serve the video files without any other HTML, you can't serve them from the database ? It's probably better to store the path to a video on your file system. Having said that, you can store them as a blob.

No, you don't. You can't access any server control at all from Javascript. The code is accessing the html elements that the server control has rendered.
The server controls only exist on the server to create the html page. Once the page is created and sent to the browser, the server controls doesn't exist any more.
mr.mohsen wrote: how can i access to the selected value property of a dropdownlist control with javascript?
You can't. You have to access the properties of the html elements that the control has rendered. Use the selectedIndex property to get the index of the selected item, then use that to get the value of the selected item.
Example:
var sel = document.getElementById('idOfTheSelectElement');<br />
var value = sel.options[sel.selectedIndex];

When your server side code generates the script for the page, it can generate script to call the method in question when the page loads.

When you run in IE, View the page source of IE see the path of that image.
and then as per that path you need to set in code like.
./images/1.jpg like that.

hi , i have build an ASP.net application using Enterprise library 1.1. Curremtly i was using sql server 2000. Now i have to take my DB to sql server 2005. my question is that my current application will work with SQL server 2005??? Is enterprise library 1.1(june 2005) work well with SQL server 2005????? please reply soon...

You've asked this in two forums. The other one is the right one. What DB you use has nothing to do with ASP.NET. Your app should work fine, but you should run your unit tests to be sure, because there are changes to T-SQL, and you never now for sure.

hi
in one of my webform's project , user can select some choice from a list.
after each select, that item insert into a temp table in my database. and ...
at last ,if user click ok button ,all selected things insert into main table.
if page closed or exit with any reason before user click ok or cancel button , in code temp table must be clear.
my problem is can not find any thing such as an event for times when user exit from the page.
how can recognize in asp.net when user exit from a page ?

In ASP.NET, you can't, but you can write AJAX code that sends a message to the server when the browser is closed, and of course you can integrate this into your ASP.NET project, although it won't use any ASP.NET libraries or code behind ( unless you choose to emit your script in your code behind ).

tanks.
exactly this solution was in my mind.
and now found is right

To handle the Browser close event you will have to write a javascript function that handles it and call the function on the OnBeforeUnload client event.
