Userpfad für mehrere Nutzer

[zeras]

Hallo,

ich möchte ein Programm schreiben, wo unter verschiedenen Nutzeranmeldungen das selbe Programm genutzt werden kann. Dazu gehören auch noch die Daten. Bei einer Einzelanwendung habe ich immer CSIDL_APPDATA genutzt, aber da hat ja ein anderer User keinen Zugriff. Welches Verzeichnis kann ich nutzen, wo alle User schreiben und lesen dürfen?

Bei den nachfolgenden Konstanten bin ich nicht weitergekommen.


CSIDL_DESKTOP = $0000;
CSIDL_INTERNET = $0001;
CSIDL_PROGRAMS = $0002;
CSIDL_CONTROLS = $0003;
CSIDL_PRINTERS = $0004;
CSIDL_PERSONAL = $0005;
CSIDL_FAVORITES = $0006;
CSIDL_STARTUP = $0007;
CSIDL_RECENT = $0008;
CSIDL_SENDTO = $0009;
CSIDL_BITBUCKET = $000a;
CSIDL_STARTMENU = $000b;
CSIDL_DESKTOPDIRECTORY = $0010;
CSIDL_DRIVES = $0011;
CSIDL_NETWORK = $0012;
CSIDL_NETHOOD = $0013;
CSIDL_FONTS = $0014;
CSIDL_TEMPLATES = $0015;
CSIDL_COMMON_STARTMENU = $0016;
CSIDL_COMMON_PROGRAMS = $0017;
CSIDL_COMMON_STARTUP = $0018;
CSIDL_COMMON_DESKTOPDIRECTORY = $0019;
CSIDL_APPDATA = $001a;
CSIDL_PRINTHOOD = $001b;
CSIDL_ALTSTARTUP = $001d; // DBCS
CSIDL_COMMON_ALTSTARTUP = $001e; // DBCS
CSIDL_COMMON_FAVORITES = $001f;
CSIDL_INTERNET_CACHE = $0020;
CSIDL_COOKIES = $0021;
CSIDL_HISTORY = $0022;

[s.h.a.r.k]

Unter Windows 7 gibts den "User" Default, unter dem z.B. Einträge im Startmenü für alle User eintragen kann.

[fatalerror]

Ich würde einen Ordner in CSIDL_COMMON_DOCUMENTS erstellen und diesen verwenden.

Ich würde einen Ordner in CSIDL_COMMON_DOCUMENTS erstellen und diesen verwenden.

Und da können alle User schreiben/lesen?
Dann wäre es ja dass, was ich brauche.

Ist nicht der korrekte Pfad für Programmdaten aller benutzer CSIDL_COMMON_APPDATA (C:\Documents and Settings\All Users\Application Data)...?
CSIDL_COMMON_DOCUMENTS bezieht sich ja auf den Pfad der Dokumente (C:\Documents and Settings\All Users\Documents), nicht auf Programmdaten.

Anbei noch eine Liste der ganzen Konstanten inklusive Erklärungen, vielleicht hilft sie ja:

        directory that contains shortcuts to the user's most recently used
        documents. A typical path is C:\Documents and Settings\username\My Recent
        Documents. To create a shortcut in this folder, use SHAddToRecentDocs. In
        addition to creating the shortcut, this function updates the Shell's list of
        recent documents and adds the shortcut to the My Recent Documents submenu of
        the Start menu.

      CSIDL_SENDTO                  (0x0009)                The file system

Jetzt verwirrt mich wieder alles.

Ich möchte einige Daten für alle User zugänglich machen. Diese sollen auch ohne Adminrechte geändert werden können. Das Progamm an sich wird direkt im Programmpfad installiert.
Das könnte eine gemeimsame Registrierungsdatei sein oder aber auch Daten, die der ein oder andere User auslesen will oder auch eintragen will.

[blackfin]

CSIDL_COMMON_APPDATA ist der richtige Ort für Programm-Daten, die für alle Benutzer gleichermaßen verfügbar sind.
Allerdings ist das Verzeichnis per Standard ohne Schreibrechte für Nicht-Admin-Benutzer.
Wenn auch von allen Benutzern Dateien verändert werden dürfen / müssen, dann hat das Installations-Programm dafür zu sorgen, den angelegten Unterordner in CSIDL_COMMON_APPDATA mit den entsprechenden Rechten zu versehen.

Das gleiche (keine Schreibrechte für nicht-Admins per Standard) gilt übrigens auch für CSIDL_COMMON_DOCUMENTS, nur dass das der falsche Ort für Programmdaten ist.

Genau so wie oben beschrieben ist es auch von Microsoft vorgesehen:

Zitat:

# CSIDL_COMMON_APPDATA

This folder should be used for application data that is not user specific. For example, an application may store a spell check dictionary, a database of clip-art or a log file in the CSIDL_COMMON_APPDATA folder. This information will not roam and is available to anyone using the computer. By default, this location is read-only for normal (non-admin, non-power) Users. If an application requires normal Users to have write access to an application specific subdirectory of CSIDL_COMMON_APPDATA, then the application must explicitly modify the security on that sub-directory during application setup. The modified security must be documented in the Vendor Questionnaire.

Der Text kommt direkt von Microsoft selbst, nachzulesen (mit vielen weiteren nützlichen Informationen über Datenspeicherung in Windows) unter folgendem Link:

http://msdn.microsoft.com/en-us/library/ms995853.aspx

Du legst also deine Programmdaten in einem Unterordner von CSIDL_COMMON_APPDATA ab und fügst diesem Schreibrechte für alle Benutzer während deiner Programm-Installation hinzu, dann ist alles in Ordnung.

[Sir Rufo]

Schau mal hier Beitrag #31

Da findest du eine Unit, mit der du auf alle "Special Folders" einfach zugreifen kannst.
Die beiliegende Demo listet alle Verzeichnisse auf inkl. der entsprechenden Rechte.
Such dir da das passende Verzeichnis aus und gut.

[fatalerror]

CSIDL_COMMON_APPDATA oder CSIDL_COMMON_DOCUMENTS welches ist nun das richtige Verzeichnis?

Das hängt _meiner_ Meinung nach von der Art der Daten ab, die dort gespeichert werden.

CSIDL_COMMON_APPDATA ist ein verstecktes Verzeichnis, das normale User also nicht zu sehen bekommen. Sollen also zum Beispiel User mit Hilfe eines Opendialogs Daten holen, sind diese Daten für normale User in diesem Verzeichnis nicht greifbar. Es empfiehlt sich hier also Daten abzuspeichern, die von deinem Programm direkt gelesen werden (zb.: Verbindungseinstellungen zu Datenbanken, Pfadeinstellungen, ...)

In CSIDL_COMMON_DOCUMENTS gehören Daten wie zb. Reports, Dokumentenvorlagen, ... die User während der Arbeit laden, verändern und speichern können sollen.

In beiden Ordnern haben aber Userspezifische Einstellungen wie Fensterpositionen, zuletzt geladene Dokumente, Skineinstellungen, Userspezifische Menu- oder Toolbareinstellungen nichts zu suchen. Diese gehören definitiv ins spezifische Userprofil.

Ich habe mal 2 Rechner auf Schreibrechte in dem Pfad überprüft. Bei beiden Rechnern (kein Admin) konnte ich mit dem Explorer einen Pfad erzeugen und auch Dateien darin ablegen. Bei dem einen Rechner habe ich einfach einen User als "Nicht Admin" angelegt und der andere ist aus meiner Firma, wo man eigentlich immer "zuwenig" freischaltet als zuviel. Auf der genannten Homepage von MS steht aber auch, dass dieser eigentlich schreibgeschützt ist.
Da werde ich wohl man in den Innosetup Info nachschauen, wie man die Pfade als "schreibend" anlegen kann.
