The DRIVER_UPGRADE_INFO_2 structure is used as an input to a printer interface DLL's DrvUpgradePrinter function.

Members

pPrinterName

Pointer to a NULL-terminated string that specifies the name of the printer. For more information, see the Comments section.

pOldDriverDirectory

Pointer to a NULL-terminated string that specifies the local directory in which the old printer driver files can be found.

cVersion

Specifies the operating system version for which the driver was written.

Value	Operating System
0	Windows 95/98/Me
1	Windows NT 3.1 through Windows NT 3.51
2	Windows NT 4.0
3	Windows 2000 and later

pName

Pointer to a NULL-terminated string that specifies the name of the driver (for example, "QMS 810"). For more information, see the Comments section.

pEnvironment

Pointer to a NULL-terminated string that specifies the environment for which the driver was written (for example, "Windows NT x86" or "Windows Itanium").

pDriverPath

Pointer to a NULL-terminated string that specifies a file name or full path and file name for the file that contains the device driver (for example, "pscript.dll").

pDataFile

Pointer to a NULL-terminated string that specifies a file name or a full path and file name for the file that contains driver data (for example, "qms810.ppd").

pConfigFile

Pointer to a NULL-terminated string that specifies a file name or a full path and file name for the device driver's configuration dynamic-link library (for example, "pscrptui.dll").

pHelpFile

Pointer to a null-terminated string that specifies a file name or a full path and file name for the device driver's help file.

pDependentFiles

Pointer to a NULL-terminated string that specifies the files the driver depends on. Each file name in the string is also terminated with a NULL (for example, "pscript.dll\0qms810.ppd\0pscrptui.dll\0pscrptui.hlp\0pstest.txt\0\0").

pMonitorName

Pointer to a NULL-terminated string that specifies a language monitor (for example, "PJL monitor"). This member can be NULL and should be specified as non-NULL only for printers capable of bidirectional communication.

pDefaultDataType

Pointer to a NULL-terminated string that specifies the default data type of the print job (for example, "EMF").

pszzPreviousNames

Pointer to a NULL-terminated string that specifies any previous printer driver names that are compatible with this driver (for example, "OldName1\0OldName2\0\0").

Comments

When DrvUpgradePrinter is called with its pDriverUpgradeInfo parameter pointing to a DRIVER_UPGRADE_INFO_2 structure, the pPrinterName member points to a string containing the name of the printer to be updated. The pName member points to a string containing the name of the printer driver to be updated, which is not necessarily the driver for the printer whose name is pointed to by the pPrinterName member.

To see how this can occur, suppose that a computer is connected to two printers, one whose driver is named "Acme Plotter" and the other whose driver is named "Acme RasterMaster". Suppose also that both drivers share a common driver file, plotui.dll. When the "Acme Plotter" driver is updated by a call to the AddPrinterDriverEx function (described in the Microsoft Windows SDK documentation), DrvUpgradePrinter is called for both printers, because both drivers use files affected by the upgrade. In both calls, the pName member points to "Acme Plotter", the name of the printer driver used in the call to AddPrinterDriverEx. The string pointed to by the pPrinterName member is different in both calls to DrvUpgradePrinter, however. In each call, pPrinterName points to the name of the printer being updated.
