Bonjour,

J'ai un problème pour utiliser GetPrivateProfileString afin de récupérer des valeurs dans un fichier INI.

Voici mon code :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
TCHAR   inBuf[80];
int res = GetPrivateProfileString(TEXT("ARCHIVAGE"), TEXT("Repertoire"), TEXT(""), inBuf, sizeof(inBuf), TEXT("Regroupement.INI"));
_tprintf (TEXT("Key: %s %d \n"), inBuf, res);

Le fichier INI en question :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
[ARCHIVAGE]
Repertoire=D:\\Temp

A l'exécution la variable inBuf est toujours vide et res est toujours égal à 0. Le fichier Regroupement.INI est bien dans le même répertoire que mon executable (créé sous Visual Studio 2010).

Il y a forcément quelque chose que je ne fait pas correctement mais quoi?

Cf. Doc MSDN http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx

lpFileName [in]
The name of the initialization file. If this parameter does not contain a full path to the file, the system searches for the file in the Windows directory.

..................

The system maps most .ini file references to the registry, using the mapping defined under the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping

..................

The profile functions use the following steps to locate initialization information:

Look in the registry for the name of the initialization file under the IniFileMapping key.
Look for the section name specified by lpAppName. This will be a named value under the key that has the name of the initialization file, or a subkey with this name, or the name will not exist as either a value or subkey.
If the section name specified by lpAppName is a named value, then that value specifies where in the registry you will find the keys for the section.
If the section name specified by lpAppName is a subkey, then named values under that subkey specify where in the registry you will find the keys for the section. If the key you are looking for does not exist as a named value, then there will be an unnamed value (shown as <No Name>) that specifies the default location in the registry where you will find the key.
If the section name specified by lpAppName does not exist as a named value or as a subkey, then there will be an unnamed value (shown as <No Name>) that specifies the default location in the registry where you will find the keys for the section.
If there is no subkey or entry for the section name, then look for the actual initialization file on the disk and read its contents.

En résumé, n'utilisez plus GetPrivateProfileString, mais la base de registre.
