sorry, i couldn't understand this.
An example:
If you have this text:
Text with "funny" characters.
and put that in a string in the code, it would be written:
string s = "Text with \"funny\" characters."
This is the way that the watch windows show it. It does so to be able to show unprintable characters like line breaks.

If a string contains quotes - which are interpretted by the compiler as start/end of string - you have to escape them to tell it that they are part of the string and not delimiting it.
Don't know about C, but in VB you can do this by by sinply doubling them - viz:
Dim str As String = ds.Tables[0].Rows[1][1].ToString.Replace(Chr(34), Chr(34) & Chr(34))
(Since Chr(34) = the quote character)
Hope that helps

This doesn't seem to help, im afraid.
istead the following seems to be a step to the solution
char[] strArr = ds.Tables[1].Rows[1][1].ToString().ToCharArray();
here strArr doesn't have the extra slashes or quotes, but now how to use this char array instead of string in my code.
As casting it back to string will get me the string with extra slashes as before.

I'm using AJAX to write Web application, there have two client (client1, client2) and server. Now i use XmlHttpRequest to send request to Server from Client1, after that, i want server send the response to Client2. But if i use Response.write(something here), Server always send to Client1, not Client2. How can i do???
Thanks!

You can't do that. The HTTP protocol simply doesn't work that way. You have to send a request from the client to be able to send a response back from the server.

So are there any way to do that? example some game online ?

Just do a request every N seconds that will ask the server if it has anything for the client. Of course you will have to write the code at the server side that will be able to do that.
But if you will only have two clients then you should defenitly write a windows application!

Hi laks here,i want some help regarding stored procedures usage,how we can use stored procedure in ASP.net,plz explain me with example
|
|
|
|
|
Stored procedures have nothing to do with ASP.NET directly.
Stored procedures are stored on a databse server, and you can call them from .NET using ADO.NET

hey i'll give you an example asp.net ( VB.net ) for executing a stored procedure in sql server 2005 but it same in another database
1) the stored procedures to add record and take the paramters from textboxes
the code for stored procedures in sql is :
create PROCEDURE SP1
(
@ID bigint ,
@Name nvarchar(50),
@Description nvarchar(500),
@ProjectID bigint
)
AS
INSERT INTO [TBASE].[dbo].[TaskType]
([ID]
,[Name]
,[Description]
,[ProjectID])
VALUES
(@ID ,@Name,@Description,@ProjectID)
RETURN
2) to execute this stored procedures from asp.net
Imports System
Imports System.Data
Imports System.Data.OleDb
Dim con As New OleDbConnection("Provider=SQLNCLI.1;Data Source=DADAX\DADAX;Integrated Security=SSPI;Initial Catalog=TBase")
con.Open()
Dim MyCommand As New OleDbCommand()
MyCommand.Connection = con
Dim proc As String
proc = "EXEC SP1 " & TextBox1.Text & ",'" & TextBox2.Text & "','" & TextBox3.Text & "'," & TextBox4.Text
MyCommand.CommandText = proc
MyCommand.ExecuteReader()
I wish that help you

Why are you using OleDb to connect to a SQL Server. Why not use a SqlConnection?

This is a security nightmare. You are advising people down the route to a SQL Injection Attack. Don't do this! See: SQL Injection Attacks and Tips on How To Prevent Them[^]

very dangerous!
using these code instead:
[C#]
SqlCommand cmd = new SqlCommand("SP1", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@ID", TextBox1.Text);
cmd.Parameters.Add("@Name", TextBox2.Text);
cmd.Parameters.Add("@Decription", TextBox3.Text);
cmd.Parameters.Add("@ProjectID", TextBox4.Text);
cmd.ExecuteNonQuery();

To show an image in an IB, just set the "ImageSrc" property.
What do you mean by "appear in another page", and show some source code and can help

hi
that's the code to retrive the image from a Ms-sql databse
===================================================
Dim stream As MemoryStream = New MemoryStream()
Try
connection.Open()
cmd = New SqlCommand("select img_name from Product_image where imageID='16'", connection)
Dim image() As Byte = CType(cmd.ExecuteScalar(), Byte())
stream.Write(image, 0, image.Length)
Dim bitmap As Bitmap = New Bitmap(stream)
Response.ContentType = "image/gif"
Bitmap.Save(Response.OutputStream, ImageFormat.Gif)
Finally
connection.Close()
stream.Close()
End Try
============================================================
the problem that i can't retrive this image in an image box it retrives in another page and i want it to appear in the same page in an image box
thanks

OK - looks like what is happening is that you're just writing the bitmap to the response stream....so essentially, what you're seeing is that the browser is "redirected" to a page with just the image on?
In order to show the image in the image box, you'd need to do something like imageBox1.ImageSrc=Bitmap
Google can help further...

Hi there,
You can place your sample code to read the image data from DB in a web page, say ShowImage.aspx, then in the web page containing the Image control, you can simply specify the ShowImage.aspx in the ImageUrl property of the Image control.
