Re: MessageBox in C#

Hi
You use

ASP.NET Syntax (Toggle Plain Text)
MessageBox.Show("This is a message");
MessageBox.Show("This is a message");

Re: MessageBox in C#

Hi.
If I do so Am gettin this error
Error The name 'MessageBox' does not exist in the current context
Do we hav to create a separate function or to use any namespace for this.

Re: MessageBox in C#

I guess the Call is done within a Form?
The MessageBox is included in the namespace System.Windows.Forms
Do you have this in your using at the top?
Or have you tried to write

ASP.NET Syntax (Toggle Plain Text)
System.Windows.Forms.MessageBox.Show("This is a message");
System.Windows.Forms.MessageBox.Show("This is a message");

Re: MessageBox in C#

MessageBox is only available in Window Applicaitons. In ASP.NET, you cannot use the MessageBox class or MsgBox function like you can in a Window Applicaitons, but you can emulate this functionality by streaming out a javascript alert instruction like this:

ASP.NET Syntax (Toggle Plain Text)
Response.Write(@"<script language='javascript'>alert('This is my Message')</script>");
Response.Write(@"<script language='javascript'>alert('This is my Message')</script>");

Re: MessageBox in C#

Okai..
This is my sample code for Palindrome checking.
Got a string in textbox 1.

ASP.NET Syntax (Toggle Plain Text)
TextBox2.Text = StrReverse(TextBox1.Text)
            If TextBox1.Text = TextBox2.Text Then
                MsgBox("String is palindrome", MsgBoxStyle.OkOnly)
            Else
                MsgBox("Not a palindrome", MsgBoxStyle.OkOnly)
            End If
TextBox2.Text = StrReverse(TextBox1.Text)
            If TextBox1.Text = TextBox2.Text Then
                MsgBox("String is palindrome", MsgBoxStyle.OkOnly)
            Else
                MsgBox("Not a palindrome", MsgBoxStyle.OkOnly)
            End If

This code is done in Asp.Net webapplication with VB code behind.
Can u say how to use message box with C# code behind
