Msgbox

rwalker · February 11th, 2004, 11:38 AM

I'm having trouble using the msgbox function in .net. I get the following error message. It is invalid to show a modal dialog or form when the application is not running in UserInteractive mode. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

Any help is appreciated.
Thanks

You can't use MsgBox in ASP.net. The code is executing on the server. Even if you could use msgbox, when a page request generated a message box, it would pop up on the server not the client's machine. If you want to generate a client-side message box you need to use a javascript alert.

I'm developing an asp.net application using visual studio .net. Can you tell me how to incorporate the java script alert in my program?

Thanks

You need to render out some javascript that looks like the following:

<script language="JavaScript">alert("This is my message box text.");</script>

Or you can put the JS function call in the body's onLoad attribute:

<body ... onLoad="alert('Here is another message.');">

Both of these need to go into the HTML markup. If you need to generate one during run-time, you can use .net's RegisterStartupScript() method. With this you need to pass in a complete script block, like the first chunk of code in this post.

msgbox is for Window app.
in order to have a alertin C# u could use the following code.

Code:

        string sWindow As = "mywindow";
        string jscript;

                jscript = "<script language='JavaScript'>mywindow = window.open('file.aspx','" + sWindow + "','height=350,width=532,toolbars=no,resizable=no')</script>";

        RegisterClientScriptBlock("mywindow", jscript);

For VB.NET, instead of MsgBox, you could use MessageBox.Show instead.

I'm not sure I understand your post bmains. Is that for ASP.NET or VB.NET forms?

VB.NET windows applications also use MessageBox.Show as an alternative to MsgBox; For ASP.NET, you need to do it in a way that planoie has above.

Thanks.

I just wanted you to clarify for other readers since Peter already covered that MsgBox was for VB.NET.

It looks confusing, like -here is another way for asp.net users to use it.

MessageBox.Show is for windows apps; using JavaScript is for web apps. There's probably another alternative or two, but that will make it even clearer.
