Then either it's not an image in JPEG format, or you are doing something wrong when you create it.
What is your code for writing the file, and what is the first few bytes of the data?
Despite everything, the person most likely to be fooling you next is yourself.

Here is the code. Please take a look.
byte intnum;
string hexnum;
string s;
s = "0xFFD8FFE000104A46494600010101013101310000FFDB004300050304040403050"
FileStream fs = new FileStream(@"F:\\users\irfan.ali\\Practice\\HotelImage.jpg", FileMode.Create);
for (int i = 1; i <= s.Length; i++)
{
hexnum = s.Substring(i,2);
intnum = Convert.ToByte("&H" + hexnum);
fs.WriteByte(intnum);
}

No wonder that doesn't work...
You have to skip the first two characters, as that is the hexadecimal prefix. If it's not present, you should start from zero, not from one.
You are decoding two characters at a time, but you are only advancing the counter by one. That means that you first decode "FF", then "FD", then "D8", then "8F", and so on.
Despite everything, the person most likely to be fooling you next is yourself.

Have you configures your SMTP correctly ?. If yes check your SMTP logs to see if the mail has been actually sent.
Thanks

In your IIS. Go to SMTP > Right Click > [Tab] General > Check Enable logging is Enabled > Properties
In that one log file directory

Hello
Do you know any way to generate asp.net page on the fly? On the fly means when user goes to page like this www.test.com/Survey it will load data from database for Survey...
I've been using redirection on the 404 error in my webconfig and then I parse aspxerrorpath to see what user want to access. But this thing works on my IIS from VS and not on the webhosts I used (bizhost.com, quantasoft.eu)
Do you know any other way how to handle that? Ah and I dont want to use query string (www.test.com/generator.aspx?id=Survey)
Below is part of my web.config:
<code> <customerrors mode="On" defaultredirect="GenericErrorPage.htm">
<error statuscode="404" redirect="Survey.aspx" />
</customerrors></code>

Hello Friends...
In my application i have to generate reports using PUSH Model.I have used the following code in my app.
public void BindReport()
{
SqlConnection myConnection = new SqlConnection();
myConnection.ConnectionString = "server=.;database=Test;uid=sa;pwd=test; ";
SqlCommand MyCommand = new SqlCommand();
MyCommand.Connection = myConnection;
MyCommand.CommandText = "Select * from EmployeeMaster";
MyCommand.CommandType = CommandType.Text;
SqlDataAdapter MyDA = new SqlDataAdapter();
MyDA.SelectCommand = MyCommand;
DataSet2 myDS = new DataSet2();
//This is our DataSet created at Design Time
MyDA.Fill(myDS, "EmployeeMaster");
// CrystalReport1 oRpt = new CrystalReport1();
// This is the Crystal Report file created at Design Time
//oRpt.SetDataSource(myDS);
// Set the SetDataSource property of the Report to the Dataset
CrystalReportViewer1.ReportSource = oRpt;
// Set the Crystal Report Viewer's property to the oRpt Report object that we created
}
But the problem is that i am not able to access the report that i have created at the design time.
Thats the main problem that i am having plase help me out.......

Dear all,
Here i have a problem with text changed event.
I have a popup calender which i will select in a textbox.
I want to check the selected date with the date, which is already entered before this record.
I want to check after selecting one date from calender, that the selected date is greater than the inserted date.
Here on textchanged event,that means user should enter data into the textbox,then only the event is firing.but it is not happening at the time of date selectd from popup calender.
My requirement is the event has to be fired on both cases,ie if the user enters date from keyboard or selects from pop-up calender.
i have tried using querystring,on databinding etc.It is not working.can anybody give me some idea.
Thanks in advance

Hi,
Try this
if (this.GridView1.Rows(rowIndex) != null)
{
//some action
}
else
{
//some action
}
where rowIndex is the index that is required to be checked.
