Tjekke forbindelse

Hey.

Jeg er igang med at lave et Remote Admin Tool (Ikke fordi jeg vil hacke - vil drille folk på netværket ;))
Det er ikke til ulovligt brug - kun sjovt .. :)

Men jeg vil bare høre hvordan man kan tjekke om man har fået forbindelse ?
Altså - man skriver en IP i et tekst felt, hvorefter den tjekker om der er forbindelse .. Hvis der er, ændre den en Label's baggrundsfarve til grøn .. Kan det lade sig gøre ? :)

Mvh
Thomas Genster

Hej Thomas

Hvis du har administrator rettigheder på dit netværk, kan du bare åbne stifinder skrive \\maskinenavn\c$ i adresse felt, og du har nu adgang til c drev på denne maskine, så kan du jo lege alt det du vil med denne maskine.
Regedit kan også åbnes andre maskiner registreringsdatabase.

Her på dette site kan du finde noget legetøj

Here er lidt kode til reboot en maskine over netværk
Lav en form "Parameter" med beskrivelse af parameterne.
/M: Message
/N: Servername ( if no name, then this server )
/S: sec. to wait for a shutdown/reboot
/C Close all application before shutdown/Reboot
/R Reboot
Ex.
NT_Shutdown /M:'10 sec. to server reboot' /N:Exchange /S:10 /C /R

Lav et Modul "Reboot" med flg. kode
