How to use MessageBox.Show () method in ASP.NET
I mean what namespace should be added...?
8  20457 
We've had this question several times in the last week or so
The answer is that it is not possible. MessageBox is part of the System.Windows. Forms namespace, but since all ASP.NET code is executed on the server not the client, you won't get a client-side popup. Theoretically, the popup will appear on the server, though I've never tested that. What is for sure is that it won't show up on the client's screen.
You will have to use Javascript for this.

Hi . Thanks a lot for your reply. I am new to the .net. I have no idea about using MessageBox.Show () method.
I tried to import different namespaces including System.Windows. Forms to make it work. But every time i got this error.
" The name 'Messagebox' does not exist in the current context "
So now i have to try this using Javascript.

Firstly" ASP.NET code is executed on the server not the client, you won't get a client-side popup"
You actually cant do that .. Though for testing purpose... u could... it u run your website.. from VS studio... on same PC.. as the web site...
Add reference to
System.Windows. Forms;
and then u can use messagebox.show (); Use only for testing purpose... In real environment the result would be different....

Since I didn't see it mentioned, it might help that in javascript it's called alert()
So in javascript code you would have: -
alert("this is my alert box messages");
-
Thank you all for the replies.....

"MySql.Data.MyS qlClient.MySqlE xception ex"?
You are connecting to Database using root'@'localhos t password: YES)??
then the problem lies with the username n password
"am getting the following error "Access denied for user 'root'@'localho st'(using password: YES)"
You are unable to connect to database with the username n password as far as i can see.

Just so you understand, that really doesn't work. If it worked for you, that's because you are probably using Visual Studio's debugging server, and you're seeing the server popup, not the client.
Simply put, MessageBox does not exist as far as a website is concerned.

Hi,
I know how the show a MessageBox in Form.h module by using VC.NET.
But I don't know how to show the MessageBox at another class such as
task.cpp which called by the Form.h; my question is how to pass the
arguments from Form.h to a MessageBox::Show() which included in a class
method.
Thanks.

I always thought writing a simple diagnostic message in a message box would
be pretty simple. Not in .NET.
First, I wrote this amazingly complex piece of code:
MessageBox.Show("yer mama")
It wouldn't even complile. "Gee...", I mused. "Maybe there's no reference
to that method in my project". I muzed correctly. So I added a reference
to System.Windows.Forms, which is where our beloved "MessageBox" method

Hi at all
i have a web application (in vb.net), and i want to use a message box

One option of the messagebox object indicates it can be placed over a
selected window rather than just appearing centered on the desktop. The
function is "Overloads Public Shared Function Show(IWin32Window, String) As
DialogResult"
I have unsuccessfully tried:
///
Dim winhandle as string
Dim rtn as DialogResult
winHandle = Me.Handle.ToString()

Hi all,
I have a VB.NET windows application that uses MDI form. When I try to delete a datagrid row from one of the MDI children forms, I use a MessageBox YesNo confirmation, which, after confirmed, minimizes the MDI form. Why is this happening and how can I prevent it?
Important thing to say is, if I use just "OK" MessageBox, it DOES NOT minimize the MDI parent.
TIA

Hi All,
I'm working on adding a message box method that will allow me to display a message to the user without waiting for the user to answer. I've done this by starting MessageBox.Show in a separate thread.
I also use a static DialogResult variable to allow me to see the user's result in my calling code. My method also accepts a MessageBoxButtons parameter that is then passed on to the MessageBox.Show method.
The only problem is that I...
