DEVNAMES structure (commdlg.h)

Contains strings that identify the driver, device, and output port names for a printer. These strings must be ANSI strings when the ANSI version of PrintDlg or PrintDlgEx is used, and must be Unicode strings when the Unicode version of PrintDlg or PrintDlgEx is used. The PrintDlgEx and PrintDlg functions use these strings to initialize the system-defined Print Property Sheet or Print Dialog Box. When the user closes the property sheet or dialog box, information about the selected printer is returned in this structure.

Syntax

typedef struct tagDEVNAMES {
  WORD wDriverOffset;
  WORD wDeviceOffset;
  WORD wOutputOffset;
  WORD wDefault;
} DEVNAMES;

Members

wDriverOffset

Type: WORD

The offset, in characters, from the beginning of this structure to a null-terminated string that contains the file name (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

Type: WORD

The offset, in characters, from the beginning of this structure to the null-terminated string that contains the name of the device.

wOutputOffset

Type: WORD

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

Type: WORD

Indicates 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 dialog box procedure for the Print property sheet or Print dialog box.
