A GUID is a Globally Unique ID, a 128-bit number that can be quickly generated with one method call, producing a hexidecimal string that can be used as a random password. To create a new GUID, use the System.Guid structure's NewGuid() method. Then, the .ToString() method can be used to create a string version of this. Here's some example code: Result = System.Guid.NewGuid().ToString();]]> 0 0 C# /PreviewSnippet.aspx?SnippetID=c52f008d-7fc8-4dbc-970b-42f215c2b777 Javascript to close a popup and refresh the parent window /PreviewSnippet.aspx?SnippetID=c52f008d-7fc8-4dbc-970b-42f215c2b777 Javascript to close a popup and refresh the parent window [HTML & Javascript] Greg Gamble Wed, 21 Mar 2007 14:07:07 GMT /PreviewSnippet.aspx?SnippetID=c52f008d-7fc8-4dbc-970b-42f215c2b777#comments de2012da-757e-4af6-8537-6799adb7bce1 Javascript to close a popup and refresh the parent window 3/21/2007 2:07:07 PM Greg Gamble ####################################################### Call the closeMe() function in the popup window and parent window will be updated, then popup will closed.
