IF it's a webpage, use AJAX, you can't call a webservice from the client. Unless you want to do it from the server, of course.
The webservice uses a standard mechanism to make requests via HTTP. It's all hidden from you, that's kind of the point.

thanks Christian,
but to sharpen my misunderstanding :
if i want to use a function that on my server with an application that seats in the client computer :
1.i need a webrefference to the webservice in my client's application to create an instance of it right?
2. the webservice shld have a method that invokes method on the server
so how do i connect to the method on the server with the webservice (using a dll?)
sorry if i'm all upside down ...

Correct.

Well, every method that is marked as such in the webservice, invokes a method on the server. Automatically. .NET hides those details from you, so you call the method and create class instances as if they were local, and the framework handles the job of making calls to the webservice and getting the result. The only difference is you need to anticipate exceptions that can occur if the framework cannot find the webservice to call.

i think my first problem is phrasing 
do these steps are right?
1.i want to use a method that seats on my server with another application
2.so i'm creating a webservice that call that method
this webservice will be part of the server solution so it will have access to the server db.
3.i want the client app to use this webservice so i add webreference to the client app and create instance of it and use its methods.
did i get it?

I was commenting on how my response got a 1/bad answer vote. If it wasn't you, then fair enough, but it seemed likely to me that it was.
Yes, you got it right. The framework handles all the messy stuff for you.

I using System.Collections.HashTable to keep some information about my database.
The information that i collect in my HashTable is -
1. string ( as the key )
2. other string ( as the value )
my problem is that i want to scan the HashTable and when the value string is equal to some parameter i want to stop my scan and check the string key value.
How can i do it ?
Thanks for the help.

By iterating over the Keys collection.

You can iterate the keys collection, and then retrieve and check the value for each key, reacting when you find your sought after value.

Hi All,
I have timespan object:
TimeSpan ts= new TimeSpan(0, 72, 1);
when i say :
MessageBox.Show(ts.ToString());
then i get: 01:12:02
What is that means?? 1 days, 12 hours and 2 minutes???
Thanx.
|

You're using this constructor:
public TimeSpan(int hours, int minutes, int seconds);
so you've created a timespan object for 72 minutes and 1 second.
which just happens to be exactly 1 hour, 12 minutes and 1 second.
(I'm assuming you've mistyped your output. it's 1 second, not 2)

Can Anyone Help
How to Remove the Duplicate Key(Repeated data) in CSV or Excel file using C# .
|
|
|
|
|
Iterate through the entries. Locate the duplicate. Remove it. Save the file.
You could locate it by adding all the entries to the collection, and checking for a clash with .ContainsKey each time.
Simon

|

is it a duplicate row or a duplicate entry in the "key" field?
If it's the latter maybe that attribute needs to be combined with another to form the key for the table

hi
in my solution, i created a table adapter and set select,insert,update,delete actions to my own stored procedures, then for add row, write the following code :
FrmCategory frm = new FrmCategory(false, false);
DsStack.CategoriesRow newRow = this.dt.NewCategoriesRow();
Session.SaveInSession("newCategory", newRow);
if (frm.ShowDialog() == DialogResult.OK)
{
newRow = Session.LoadFromSession("newCategory") as DsStack.CategoriesRow;
this.dt.Rows.Add(newRow);
this.adapter.Update(this.dt);
}
When my table in database is empty :
the first row add to table successfully, but the second row has not been add to database and the following error has shown me :
Concurrency violation: the UpdateCommand affected 0 of the expected 1 records.
where does my problem and how to solve it ?
thanks

Your Update method waiting for 1 record to be updated, but your update sp doesn't update any row.
Check you sp manually, sent the same values by parameter and watch the results.

|

thanks for replies
my sp code is :
Create Procedure [dbo].[sp_Categories_Insert]
@categoryName nvarchar(30),
@description nvarchar(400)
As
Begin
Insert Into Categories
([categoryName],[description])
Values
(@categoryName,@description)
Declare @ReferenceID int
Select @ReferenceID = @@IDENTITY
Return @ReferenceID
End
do i change sp code ?
|
|
|
|
|
When You run this proc, what the value of @ReferenceID?
|
|
|
|

Hi alex
the ReferenceID is PK of Inserted Row
