ADS_ESCAPE_MODE_ENUM enumeration

The ADS_ESCAPE_MODE_ENUM enumeration specifies how escape characters are displayed in a directory path.

Syntax


typedef enum  { 
  ADS_ESCAPEDMODE_DEFAULT  = 1,
  ADS_ESCAPEDMODE_ON       = 2,
  ADS_ESCAPEDMODE_OFF      = 3,
  ADS_ESCAPEDMODE_OFF_EX   = 4
} ADS_ESCAPE_MODE_ENUM;

Constants

ADS_ESCAPEDMODE_DEFAULT

The default escape mode provides a convenient option to specify the escape mode. It has the effect of minimal escape operation appropriate for a chosen format. Thus, the default behavior depends on the value that ADS_FORMAT_ENUM uses to retrieve the directory paths.

Retrieved path format	Default escaped mode
ADS_FORMAT_X500	ADS_ESCAPEDMODE_ON
ADS_FORMAT_X500_NO_SERVER	ADS_ESCAPEDMODE_ON
ADS_FORMAT_WINDOWS	ADS_ESCAPEDMODE_ON
ADS_FORMAT_WINDOWS_NO_SERVER	ADS_ESCAPEDMODE_ON
ADS_FORMAT_X500_DN	ADS_ESCAPEDMODE_OFF
ADS_FORMAT_X500_PARENT	ADS_ESCAPEDMODE_OFF
ADS_FORMAT_WINDOWS_DN	ADS_ESCAPEDMODE_OFF
ADS_FORMAT_WINDOWS_PARENT	ADS_ESCAPEDMODE_OFF
ADS_FORMAT_LEAF	ADS_ESCAPEDMODE_ON

ADS_ESCAPEDMODE_ON

All special characters are displayed in the escape format; for example, "CN=date\=yy\/mm\/dd\,weekday" appears as is.

ADS_ESCAPEDMODE_OFF

ADSI special characters are displayed in the unescaped format; for example, "CN=date\=yy\/mm\/dd\,weekday" appears as "CN=date\=yy/mm/dd\,weekday".

ADS_ESCAPEDMODE_OFF_EX

ADSI and LDAP special characters are displayed in the unescaped format; for example, "CN=date\=yy\/mm\/dd\,weekday" appears as "CN=date=yy/mm/dd,weekday".

Remarks

Special characters must be escaped when used for any unintended purposes. For example, LDAP special characters, the comma (,) and the equal sign (=), are intended as field separators in a distinguished name, "CN=user,CN=users,DC=Fabrikam,DC=com". When an attribute value uses such special characters, for example, "CN=users\,last name\=Smith", these special characters must be escaped as shown. This ensures that an LDAP-compliant directory, such as Active Directory, will parse the path properly. However, an escaped path string may not appear to be user-friendly on a display. In this case, you can set the ADS_ESCAPE_MODE_ENUM in such way that shows the path as an unescaped string, "CN=users,last name=Smith".

Similarly, the ADSI special character, slash mark (/), separates ADSI-specific elements, "LDAP://server/CN=Jeff Smith,CN=Users,DC=Fabrikam,DC=com". Although it must be escaped when used for any other purposes, for example, "LDAP://server/CN=Jeff Smith\/California,CN=Users,DC=Fabrikam,DC=com". You can choose an ADS_ESCAPE_MODE_ENUM option to display this escaped string in a human-readable form: "LDAP://server/CN=Jeff Smith/California,CN=Users,DC=Fabrikam,DC=com".

Presently, the slash mark (/) is the only ADSI special character. ADSI escaping and unescaping applies to ADSI special characters only. The operation will not affect any LDAP special characters, that is, they are neither escaped nor unescaped. For more information and a list of special characters defined by LDAP, see LDAP Special Characters.

To show unescaped path string, use the IADsPathname interface and its methods. All other ADSI APIs return the escaped path string.

To obtain correct behavior, the LDAP special characters must be escaped before the ADSI special characters are escaped. The IADsPathname interface will escape the characters in the correct sequence.

Note Because VBScript cannot read data from a type library, Visual Basic Scripting Edition (VBScript) applications do not recognize symbolic, as constants defined above. Instead, use the numerical constants instead to set the appropriate flags in your VBScript applications. To use the symbolic constants, write explicit declarations of such constants, as done here.
