Starten von Programmen aus einem Service ...

[thenoname]

Hallo,

nachdem ich nun einen Service erzeugen konnte,
habe ich das Shellexecute ausprobiert und festgestellt, das
dieses aus einem Service heraus keine Wirkung hat
Wie macht man es dann ?
Es geht praktisch darum, das man OHNE eingeloggt zu sein
ein Programm mit einem Benutzerkonto starten kann.
Oder so ähnlich ...

Teste mal eine der Beiden Funktionen aus folgender Datei (code in ne .h datei speichern un din Projekt einbilden) ... in meinen Service funktionierts so ...
hab diese Funktionen mal von www.codeguru.com geloadet ... hab sie also nicht selbst geschrieben! (damit keiner denkt ich würd code stehlen und ihn für meinen ausgeben ) ...

Ja,
die CreateProcess habe ich nun auch verwendet ...
Klappt gut, auch ohne weitere Prameter. Die zwei letzten
Strukturen sind bei mir mit zero gefüllt, dürfen aber nicht
NULL sein.
Habe allerdings festgestellt, das bei fehlender Datei es einen
Crash des Services gibt ...
Nun kann ich also ohne logon Programme starten, wenn ich eine
Joysticktaste drücke. (naja, wers halt braucht)

Desweiteren gibt es noch CreatProcessWithLogonW und CreateProcessAsUser.
Die sind allerdings erst ein Studium wert, um Nutzen ziehen zu können.

Danke für den Code ...

Freut mich, dass ich Dir helfen konnte,
aber wollte mal fragen, ob Du auf folgendes Problem, was ich grad habe ne antwort hast:

Ich bastle grad einen Service ... hat bis jetzt auch gut geklappt, wollte
jetzt allerdings ein Client Programm schreiben was den Service Verwaltet (Einstellungen ändert usw.) deshalb hab ich eine CAsyncSocket klasse geschrieben. ich hab die Klasse in einer "normalen" Dialogfeld Anwendung getestet, sie funktioniert einwandfrei (is nur zum test, die sendet wenn man irgendwas an sie sendet einfach ein "hallo" zurück, dieser Send befehl steht inder überschriebenen OnReceive Funktion) , wenn ich diese Klasse aber in dem Service Einbinde kann man zwar connecten, aber die überschriebene OnAccept Funktion wird nie ausgeführt, wodurch man ja nich richtig connectet ist ... ich hab die Vermutung, dass in einen Service solche ereignisse, wie Connecting und Receive nicht augelöst werden, oder liege ich da falsch ?!? (hab bis jetzt mit Services keine Erfahrung, und mit Sockets nur nen bisschen *g* ) ...

hab das schon allgemein als Thema gepostet, hat noch keiner geantwortet, aber ich dachte du hättest vielleich davon Ahnung ????!!!!???

[acer]

post mal den code den du bis her hast!
dann können wir besser analysieren!

ja ich poste erst mal nen Teil .. is nämlich viel .... ich glaub dass es daran liegt, dass so was wie die MessageMap von nen "normalen" Windows Programmen dort fehlt (is aber nur so ne Vermutung ... ich bin nich soo der Held, was WinAPI Programmierung angeht ) ... aber hier erst mal der Code:
