I agree with Brji...
But there may be another way.
I try to stay away from client side JavaScript. It's too hard to debug and test. But you could always have the "Next" button postback and make a decision to continue (Response.Redirect(whatever.aspx) or to not continue based on the entered information. I do it quite frequently, but I come from a WinForms background where I'm used to having fine control over the actions of the user. I think anytime you rely on JavaScript, you will get burned in the long run with compatibility issues anyway.

hey,
I got a problem related with mail server. i tried to send email from asp.net. my code is
MailMessage message = new MailMessage("sm@hotmail.com", "sm@hotmail.com");
message.Subject = "Project Request";
message.Body = "Project named " + txtProjectTitle.Text + "has arrived";
message.Priority = MailPriority.High;
SmtpClient client = new SmtpClient("localhost");
client.Send(message);
But i doubt in the smptclient part. I gave localhost but it is giving error like
<pre lang="msil">System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:25 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace --- at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) at System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpTransport.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) --- End of inner exception stack trace --- at System.Net.Mail.SmtpClient.Send(MailMessage message) at ProjectRequestTest._Default.btnSubmit_Click(Object sender, EventArgs e) in C:\Documents and Settings\sm\My Documents\Visual Studio 2008\Projects\ProjectRequestTest\ProjectRequestTest\Default.aspx.cs:line 50</pre>
How to solve it ? or what client name do I have to give and how do I know that name ?
Thanks in advance,

Are you running a smtp service on your pc? Probably not.
In most cases you should use the smtp relay host that your ISP has assigned to you. If you are in a corporate environment, ask you mail administrator which servers to use, and what the the restrictions are.
And last, don't put your email address in your post, if you don't want to get spammed to death with male erectile enhancers, cheap diplomas, and Nigerian dictators who need someone to cart their fortune out of the country.

hii friends, my line of code is
dv.RowFilter = "Date=" + Convert.ToDateTime(reportdate);
Date is the name of a column in my table and is of type Datetime.
reportdate is a variable of type string.
I am getting this SyntaxErrorException.
Syntax error: Missing operand after '12' operator.
plz help me to solve this error.
Thanks.
|
|
|
|
|
try this
dv.RowFilter = String.Format(CultureInfo.InvariantCulture.DateTimeFormat,
"Date = #{0}#", Convert.ToDateTime(reportdate));
It should work.
|
|
|
|
|
now it is saying like this
Cannot perform '=' operation on System.String and System.DateTime.
|
|
|
|
|
your Date column is of which time? string or Datetime. Both should be same.
And also one more in which format the date is in dataview. Both should be same.Accordingly convert the datetime object.
|
|
|
|
|
the Date column is of datetime type.
reportdate is of type string and contains "01/01/10"
in the dataview the format of Date is as follows
#01/01/2010 00:00:00#
|
|
|
|
|
As I suggested put the use the dataetime objects in same format at both end.
Have a look to this link
|
|
|
|
|
Enclose the date in single quotes
dv.RowFilter = string.Format("Date='{0}'", Convert.ToDateTime(reportdate));
I know the language. I've read a book. - _Madmatt
|
|
|
|
|
now am getting
Error: String was not recognized as a valid DateTime.
dv.RowFilter = string.Format("Date='{0}'", Convert.ToDateTime(reportdate));
the reportdate contains "01/01/10"
and in the dataview the format of date is:
Date='1/1/2010 12:00:00 AM'
is this error because of the date formats? if so how to make them compatible.
|
|
|
|
|
DateTime dt;
if(DateTime.TryParse(reportDate, out dt))
{
dv.RowFilter = string.Format("Date='{0}'", dt);
}
or the overload
if(DateTime.TryParse(reportDate, IFormatProvider, Style, out dt))
I know the language. I've read a book. - _Madmatt
|
|
|
|
|
If you don't care about the time portion use this
<br />
dv.RowFilter = string.Format( "Date='{0}'", reportdate.ToString("dd/MM/yyyy");<br />
|
|
|
|
|
still i could not solve it.
i am getting the following error when i am trying this..
dv.RowFilter = string.Format("Date='{0}'", reportdate.ToString("dd/MM/yyyy"));
The best overloaded method match for 'string.ToString(System.IFormatProvider)' has some invalid arguments
|
|
|
|
|
Sorry, I didn't realize that you were using the string value. To use the string, use
<br />
dv.RowFilter = string.Format("Date='{0}'", Convert.ToDateTime(reportdate).ToString("dd/MM/yyyy"));<br />

You need to work on CSS. Need to create different css class insted of giving direct value in aspx page.

hi , iam using asp.net with c#
iam displaying images using Handler.ashx but when there is no image present in a database i want to display nopic.jpg picture
can you correct my code which helps me
using System;
using System.Web;
using System.IO;
using System.Data;
using System.Data.SqlClient;
public class left1old : IHttpHandler {
public void ProcessRequest (HttpContext context)
{
int branchid = 0;
if (context.Session["branchid"] != null)
branchid = Convert.ToInt32(context.Session["branchid"]);
else
throw new ArgumentException("No parameter specified");
context.Response.ContentType = "image/jpeg";
Stream strm = ShowImage(branchid);
byte[] buffer = new byte[4096];
int byteSeq = strm.Read(buffer, 0, 4096);
while (byteSeq > 0)
{
context.Response.OutputStream.Write(buffer, 0, byteSeq);
byteSeq = strm.Read(buffer, 0, 4096);
}
}
public Stream ShowImage(int branchid)
{
SqlConnection con = new SqlConnection(" Data Source=.; Initial Catalog=SafaView;User ID=sa;Password=nsg_ss_0103;");
string sql = "SELECT imgleft1old FROM tblImages WHERE BranchId = @branchid";
SqlCommand cmd = new SqlCommand(sql, con);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@BranchId", branchid);
con.Open();
object img = cmd.ExecuteScalar();
try
{
return new MemoryStream((byte[])img);
}
catch
{
return System.IO.Stream("~/images/NoPic.jpg");
}
finally
{
con.Close();
}
}
public bool IsReusable {
get {
return false;
}
}
}
in page load
=============
protected void Page_Load(object sender, EventArgs e)
{int i=0;
i= Convert.ToInt32(Session["branchid"]);
if (IsPostBack == false)
{
Image1.ImageUrl = "left1.ashx?BranchId=" + i;
Image2.ImageUrl = "left1old.ashx?BranchId=" + i;
}
can you correct my code which helps me
|

Why tyou are using try catch, it is performance overhead, its better you return the nopic image from db itself, put it in some common table, if there is noimage for that record return nopic image, also you can read as you are doing, just check if there is nothing in image read it from localdrive and send it in the same format.
try to debug the code you'll get to know the exact problem

What u can do is keep a blank image in ur websites image folder and just check
MemoryStream strm = new MemoryStream((byte[])img);
if (strm.Length <= 0)
{
//Then load the blank image
}

I can see a couple of issues with the code:
developerit wrote: return System.IO.Stream("~/images/NoPic.jpg");
Should this be:
return new System.IO.Stream(Server.MapPath("~/images/NoPic.jpg"));
It would help if you could tell us what the error is that you're seeing...
