I'm guessing they do the co-ordinate grabbing with javascript, not a java applet. Then they just crop on the server. That part is obviously trivial, once you have the coordinates.

He gave you an idea how they might do it. Makes sense and shouldn't be that difficult to implement.

I'm not sure what you want, or how it relates to ASP.NET.

I would suggest that if you don't know, you're not likely to pass. I personally have no idea.

Amit,
I don't think that this is right community where you can get an answer to your question. 
In between, as you said you want to do some project on Firewall, but it is itself a huge topic to discuss. What I would suggest will be to select a topic on your own(that means what exactly you want to do).
Technology / Language is the secondary thing which could be decided after you have the requirements.

Write a javascript function which can check the extension of the file before uploading.

hi friends,
I have a sp for delete like this
ALTER procedure [dbo].[pr_DeleteCampus]
(
@campuscode smallint
)
as
delete from campus
where campuscode = @campuscode
but when i pass the parameter in the method and do NUit test like this
public void deletecampus(int campuscode)
{
campuscode = 7;
Assert.That(7, Is.Not.EqualTo(campuscode));
}
It throws an error
Sql Error Exception:Exception Procedure or Function sp_name expects parameter '@campuscode',which was not supplied.

This code doesn't call the proc, so a piece is missing.

I have a dll which calls the procedure. The same method works for select stored procedure option.

Hello,
I'm doing bit of fire fighting here on an old piece of code written by someone else. Its an application in Arabic.
In the application currency is formatted using VisualBasic functions and string formatting. Example:
FormatCurrency(amount, 3)
This is how currency is displayed now: 123،34.342 ر.ع
But they want it to displayed with different group separator and decimal separator, like 123,34/342 ر.ع
I have created a function like this:
Private Sub SetCulture(ByVal culture As String, ByVal useUserOverride As Boolean)
Dim cultureToUse As New System.Globalization.CultureInfo(culture, useUserOverride)
cultureToUse.NumberFormat.CurrencyDecimalDigits = 3
cultureToUse.NumberFormat.CurrencyDecimalSeparator = "/"
cultureToUse.NumberFormat.CurrencyGroupSeparator = ","
cultureToUse.NumberFormat.CurrencySymbol = "ر.ع."
Threading.Thread.CurrentThread.CurrentUICulture = cultureToUse
Threading.Thread.CurrentThread.CurrentCulture = cultureToUse
End Sub
I call this function like
Me.SetCulture("ar-OM", False)
But Currency group separator is still the old one. The regional settings of server where I'm testing this app is set to English. I tried with English and Arabic(Oman) in my local PC regional settings, currency is displayed the way I want only if I set English settings. But here in Oman, people mostly set their Windows for Arabic language. Could someone point out what I'm doing wrong here?
Regards,
Blumen

hi
how can i use onmouseover i want to show large image size. my image is filled from database and show in grid view. and how i apply this javascript.
I will do my best?

The javascript needs to change the size of the image tag, so the image grows.

for shoppigcart I use session or cache?whitch on is better?why?
(a customer select the item and can go to shoppingcart page and edit the order and then when the customer click the save button ,orders save in database.)
|
|
|
|
|
Session or cache ? It shows you have no idea about what it is. Please purchase a book and learn ASP.NET.
Session : Specific to user
Cache : Available to all users
|
|
|
|
|
In this case you have to use session, because Session is based on user. where cache is common for all user.
you can use Cache where data for all user same.
cheers,
Abhijit

A more reliable implementation would be to have a temporary orders table you can save selections to this table up until the "check out" procedure.
A vistior comes, you check for a cookie (shopper=1234), if they have the cookie you can query the temp table for previous orders, if they don't have the cookie, tag them with one.
Any selection is saved to the temp table using the shopper id from the cookie. Once at check out, their cart would have items from the temp table, push these items to the real store/basket table. Once the order has been processed - do whatever.. removing the entries from the temp table. Once a month, once a week or every 24 hours, purge the temporary table to relieve bloating.
Something like that should work and it would be more reliable. Relying on session or cache is never a good idea - both can expire unexpectedly.
