Hi, u should check out the Microsoft.WindowsMobile.Status-Namespace. The SystemStatus-Class provides several fields which could be useful to getting the cradled-state and network-status. Best Regards, David

Hi Jun, normally u should use the MDC (currently v6.1: http://www.microsoft.com/download/en/details.aspx?id=3182[^])... im working with that on different win7 machines - never failed installing on those. but im admin on all of them... so no clue, if not beeing admin is a problem... best regards, david
