)

Remarks

It is recommended that the whole implementation of this method is encapsulated in a try-catch block like this: try { // implementation } catch (Exception ex) { RememberHtmlExceptionMessage(ex); } The RememberHtmlExceptionMessage(Exception) method will store any error data and provide it later for formatted output to the client. Using the RememberHtmlExceptionMessage(Exception) method also allows to collect multiple errors' data in order to diagnose possible problems more easily.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
