The DEVNAMES structure contains strings that identify the driver,
device, and output port names for a printer. The PrintDlg
function uses these strings to initialize members in the system-defined Print
dialog box. When the user closes the dialog box, information about the
selected printer is returned in this structure.
typedef struct tagDEVNAMES { // dvnm
WORD wDriverOffset;
WORD wDeviceOffset;
WORD wOutputOffset;
WORD wDefault;
// driver, device, and port name strings follow wDefault
} DEVNAMES;
Members
-
wDriverOffset
-
(Input/Output) Specifies the offset in characters from the beginning of this
structure to a null-terminated string that contains the filename (without the
extension) of the device driver. On input, this string is used to determine
the printer to display initially in the dialog box.
-
wDeviceOffset
-
(Input/Output) Specifies the offset in characters from the beginning of this
structure to the null-terminated string (maximum of 32 bytes including the
null) that contains the name of the device. This string must be identical to
the dmDeviceName member of the DEVMODE
structure.
-
wOutputOffset
-
(Input/Output) Specifies the offset in characters from the beginning of this
structure to the null-terminated string that contains the device name for the
physical output medium (output port).
-
wDefault
-
Specifies whether the strings contained in the DEVNAMES structure
identify the default printer. This string is used to verify that the default
printer has not changed since the last print operation. If any of the strings
do not match, a warning message is displayed informing the user that the
document may need to be reformatted.
On output, the wDefault member is changed only if the Print Setup
dialog box was displayed and the user chose the OK button. The DN_DEFAULTPRN
flag is used if the default printer was selected. If a specific printer is
selected, the flag is not used. All other flags in this member are reserved
for internal use by the Print Dialog box procedure.
