How to create a very simple Message Box in webform1.aspx >.<

[Man]

Forgive for my noobness... i try msgbox or even MessageBox.Show(), but none of them seems working...
Anyone got a simple code or simple sample to show? thanks a lot

MessageBox is a Windows Form component and can't be used in ASP.NET. If you want to display a message box (javascript alert) you can do this

Dim strScript As String
 
strScript = "<script>"
strScript = strScript & "alert('Test');"
strScript = strScript & "</script>"
 
Page.RegisterStartupScript("ClientScript", strScript)
