Displaying a MessageBox 1

[nevets2001uk]

On the application I'm developing I'm building in some error trapping systems. During the testing phase I would like to display the error messages in a messagebox.

I believe you can use the following code...

MessageBox.Show(blah blah)

I'm using this from within a class I've written and I'm not sure of what should come before the MessageBox to allow me to use it. At the moment it is saying that MessageBox is not declared.

Thanks in Advance!

Server side events run at the Web Server. Telling the Server to display a MessageBox wouldn't work even if allowed as it's the client you want to see the MessageBox on, (within the Web Browser).

You can't display a MessageBox in the way that you want because there's actually no such thing with ASP.net, basically for the above reasons. There is the javascript 'window.confirm' and 'window.alert' but these are client side scripting, not code behind.

I would look at setting up a basic HTML page that you can send the Error details to, and open, from within the catch blocks of your error handling.

Thanks for the quick reply. I'm testing on the server at the moment. So is there a way to display an error message on the server PC or is that equally as impossible?

Equally impossible I believe. MessageBox is part of Windows Forms and does not exist in ASP.net. There are the client side scripting functions to provide a client side message box, but you'd need to pass them the server side error details, which gets a little complicated for a simple development environment error handler.

I'll log my errors in a different way then. Thanks for you help.

Steve,

I always have a lblError located on my page and then any error that I come across I set the .Text equal to the message of the error or the message that I want displayed.

Hope this helps!

Hope everyone is having a great day!

Thanks - Jennifer

Thanks for the suggestion Jennifer. It's something I may include for some of my testing.

Message boxes ARE available through ASP.Net. This is how you can have the validation summary appear in a message box:

<asp:ValidationSummary
HeaderText="The following errors were found"
DisplayMode="List"
ShowMessageBox = "True"
runat="server" >

Page.RegisterStartupScript()

is a great way to emit client side script to the browser via server side code:

string errorMsg = "Your code blew up. Sorry.";
string script = "<script language=javascript>alert('" + errorMsg + "');</script>";
Page.RegisterStartupScript("error",script);
