The challenge of a progress bar as you noted, server-or client-side, is difficulty of what to base the increment on during the query. Building on the suggestion of the first reply, how an animated gif image that symbolizes the query is running, combined with a counter that increments in seconds as the process running. Also, a message that warns searches could take from X - Y seconds, just so they don't think it's locked up. Those three elements might make the wait more bearable for the user.

I have not used that specific captcha technique I mentioned, but I do use ImageMagick (IM) with ASP.NET. I have a pretty basic article on COde Project about generating previews from uploaded images with IM, Using ImageMagick to Create Previews and Thumbnails from Uploaded Images[^]. This is similar to what you are trying to do by creating a dynamic image and return it to the browser. The key method is CallImageMagick(string fileArgs). You pass your argument, such as the captcha command, which defines the distortions and the output path of the file. The random string used to create the captcha using IM would be stored and used to verify the user response to the captcha challenge. IM is easy to download and install. The latest update which I just installed on our server was "ImageMagick-6.6.0-7-Q16-windows-dll.exe". Make sure to check the last install option - "Install ImageMagickObject OLE Control...", so that MagickCMD.exe will be installed. You will need to provide the path to this file in your code; see my article. There are several other good articles on CodeProject about using IM with ASP.NET. That is where I learned about it.

You could do it on the client-side with jQuery and save a lot of server-side processing and roundtrips. It would be easy to attach an event listener to the checkbox and total all the item's subtotals, etc. Here is a link to an example that updates the total the items in the order table as you add and remove items. It doesn't use Web Forms, but just as easily could: Interactive Form Functionality on the Client-Side Using jQuery[^]. There is a working example at http://altweb.lazerinc.com/jquery/order_dev.htm[^].

Have you considered using ImageMagick? We use it for a number of similar processes. Fred's ImageMagick Scripts contains a captcha sample script: http://www.fmwconcepts.com/imagemagick/captcha/index.php[^]

We have a sales program that allows the user to view the sales report on screen, contained in a paged GridView. The user has the option to print the report. When they select 'Print', the code: 1. Modifies the GridView to display all rows (vs. paging) by changing the PageSize property. 2. Hides all extraneous page elements by modifying their Visible properties. 3. Changes the page's Theme from a screen oriented theme to a theme optimized for printing by modifying (Page.Theme and Page.StylesheetTheme) properties. 4. Calls the browser's print command via JavaScript. Hopes this helps answer your question.

I agree with the previous comment, it seems like your SMTP mail server must be configured incorrectly in your web.config file. I tested your code (slightly modified), using localhost as the mail server; it worked just fine.

//Test Strings
string TxtEmail = "Sue.Smith@123.com";
string TxtName = "Sue Smith";
string TxtMessage = "This is a test email message.";

using(MailMessage message = new MailMessage())
{
message.From = new MailAddress(TxtEmail, TxtName);
message.To.Add(new MailAddress("rohanrajpoot@in.com"));
message.Subject = "This person has contacted us!";
message.IsBodyHtml = false;
message.Body = TxtMessage;
SmtpClient smtpClient = new SmtpClient { Host = "localhost" };
smtpClient.Send(message);
}

I tested your div tag, shortened to 100 px to force a vertical scroll bar, with a DataGrid loaded with data in VS2008. It worked just fine in IE8 and Mozilla 5. There has to be more to the story (code), to 'break' it, as the earlier commenter said.

<div style="height: 100px; overflow: auto;">
<asp:DataGrid runat="server" DataSourceID="LinqDataSource1"></asp:DataGrid>
</div>

If I understand your question, Leveling should inherit CharClasses and use the base constructor characterClass, as follows: Leveling lvl = new Leveling("Warrior");

public class CharClasses
{
public int healthPoints = 0;
public int manaPoints = 0;
public int strength = 0;
public int dexterity = 0;
public int speed = 0;
public int intelligence = 0;

public CharClasses(string characterClass)
{
    if(characterClass == "Warrior")
    {
        healthPoints = 100;
        manaPoints = 10;
        strength = 10;
        dexterity = 5;
        speed = 3;
        intelligence = 0;
    }

    if(characterClass == "Archer")
    {
        healthPoints = 75;
        manaPoints = 10;
        strength = 3;
        dexterity = 10;
        speed = 5;
        intelligence = 0;
    }

    if(characterClass == "Assassin")
    {
        healthPoints = 75;
        manaPoints = 10;
        strength = 5;
        dexterity = 3;
        speed = 10;
        intelligence = 0;
    }

    if(characterClass == "Mage")
    {
        healthPoints = 50;
        manaPoints = 50;
        strength = 0;
        dexterity = 5;
        speed = 3;
        intelligence = 10;
    }
}

}

public class Leveling : CharClasses
{
public int level = 1;
public int experience = 0;

public Leveling(string characterClass)
    : base(characterClass)
{
    if(experience == ((experience + 100) \* 1.5))
    {
        level++;
    }
}

}

If you use inheritance, and don't need to instantiate CharClasses directly, you may want to change you your access modifiers from all public to protected, etc.

I dug up an old (2002 old) classic ASP/VB site I created that required the user to enter a username and password, which is checked against the database. If they are successful, a session variable in the global.asa file is set to true. Each page checks the variable first and bounces the user if the variable returns false. Top of each page:

'Check if user is logged in
Dim LoggedIn
LoggedIn = Session("LoggedIn")
If LoggedIn <> "True" Then
Response.Redirect("login.asp")
End If

global.asa

Sub Session_OnStart
'Create a Session variable to track if the user has logged in
Session("LoggedIn") = "False"
...
End Sub

Hope this helps.

I realize this doesn't answer your code-specific question, but is zipping the files an option? It will provide better speed and reliably, and limit your attachments to a single file. You can use the System.IO.Compression class to compress the stream of files. Advantages of zipping files for email: Zip or unzip a file[^]

If I understand your question correctly, wouldn't setting the columns Visible property to false provide you with the solution you seek (Visible="false"). This is a very common technique.

I've used theMessage.BodyEncoding = Encoding.UTF8; Is using Encoding.Unicode better for Arabic than Encoding.UTF8?

I would use Application.Exit(); after completing the work, to exit the Form and the application. MSDN: http://msdn.microsoft.com/en-us/library/ms157894.aspx[^]

If I understood your question, you have a background you wish to transition (blend) from one color to another, but want the blend to dynamically scale to the height of the menu. I believe this article will solve your problem, using JavaScript: http://www.elctech.com/snippets/javascript-color-fade-function-find-the-hex-value-between-two-hex-values[^]

If I understood your question correctly, you do not want to penalize the user for the time it takes the Page to PostBack. Why don't you add an OnClick() event to the Next button to capture the time remaining and send it to a Session variable, first, before calling the next question, etc. Then once the page has posted back you can retrieve the time remaining from the Session variable?

Regards, Gary

I agree with first two answers. Does it have to be the Enter key? Using the Tab key with TabIndex to indicate a specific indexing of controls is easier and more standard. Enter will cause a Submit on the form?

Yes, the first answer (Computafreak's) is correct, Response.Write(ex.Message); if your writing an ASP.NET Web Application. But, looking at your code, I suspect you are writing a Windows Application due to your reference to Console.WriteLine(). This is a stretch, you want to send a Windows Application generated error message to a web browser window? Who's browser - yours, or a user of the application? At what URL? I think you may want to CLARIFY your question with some more details on the type of application you are writing.

Hidden field, use Request.Form instead:

string fname = "";
if (Request.Form["customer_fname"] != null)
{ fname = Request.Form["customer_fname"]; }
Response.Write("fname value: " + fname);

You point your message to your email server. For example:

using System.Net.Mail;

class Emailer
{
private void SendEmail()
{
MailMessage theMessage = new MailMessage();
MailAddress whoTo = new MailAddress("John.Doe@abc.com", "John Doe");
MailAddress whoFrom = new MailAddress("Sue.Smith@123.com", "Sue Smith");
theMessage.To.Add(whoTo);
theMessage.From = whoFrom;
theMessage.Subject = "Real Important Message";
theMessage.Priority = MailPriority.Normal;
theMessage.Body = "This is a real important email message.";
theMessage.IsBodyHtml = true;

    SmtpClient client = new SmtpClient();
    client.Host = "mail.123.com"; // <- Your email server goes here
    client.Send(theMessage);

}

}
