Syntax

    DWORD   dwFlags;

Members

dwSize

Size of the DPAPPLICATIONDESC structure, dwsize = sizeof(DPAPPLICATIONDESC).

dwFlags

Not used. Must be zero.

lpszApplicationNameA, lpszApplicationName

Pointer to a string containing the name of the application. Note: This title should not be localized. Use the lpszDescriptionA and lpszDescriptionW members to localize the application name.

guidApplication

Globally unique identifier (GUID) of the application. This should be the same as the value used in the guidApplication member of the DPSESSIONDESC2 structure when hosting a game session.

lpszFilenameA, lpszFilename

Pointer to a string containing the name of the executable to be launched. Note: The use of a stub executable should be avoided when launching from a lobby. In a lobby launch scenario, the stub should be bypassed and the main executable should be launched.

lpszCommandLineA, lpszCommandLine

Pointer to a string containing command line arguments to be passed to the executable when launched by a lobby.

lpszPathA, lpszPath

Pointer to a string containing the path where the executable is located.

lpszCurrentDirectoryA, lpszCurrentDirectory

Pointer to a string containing the path that the current directory should be set to. Typically, this is the same as lpszPath or lpszPathA.

lpszDescriptionA

Pointer to an ANSI single-byte character string containing a localized description of the application. When EnumLocalApplications is called on an ANSI interface (such as IDirectPlayLobby3A), this string will be returned if it is present. Otherwise, the lpszApplicationName data member will be returned. Note: This string should not contain any multi-byte characters. Set to NULL if no localized ANSI description is needed.

lpszDescriptionW

Pointer to a Unicode sting containing a localized description of the application. When EnumLocalApplications is called on a Unicode interface (such as IDirectPlayLobby3), this string will be returned if it is present. If it is not present, the lpszDescriptionA data member will be converted to Unicode and returned. If neither lpszDescriptionA nor lpszDescriptionW is present, the lpszApplicationName data member will be returned. Note: This string must consist solely of Unicode characters. Set to NULL if no localized Unicode description is needed.
