GetPrinterDriver
The GetPrinterDriver function retrieves driver data for the specified printer.
BOOL GetPrinterDriver(
HANDLE hPrinter,
| // printer object
| LPTSTR pEnvironment,
| // address of environment
| DWORD Level,
| // structure level
| LPBYTE pDriverInfo,
| // address of structure array
| DWORD cbBuf,
| // size, in bytes, of array
| LPDWORD pcbNeeded
| // address of variable with number of bytes retrieved (or required)
| );
|
|
Parameters
hPrinter
Identifies the printer for which the driver data should be retrieved.
pEnvironment
Points to a null-terminated string that specifies the environment. For
example, "Windows NT x86" specifies Windows NT running on an Intel 80386 or 80486
processor. If this parameter is NULL, the current environment of the calling
application and client machine (not of the destination application and print server)
is used.
Level
Specifies the version of the structure to which lpbForm points. This value must be either 1, 2., or 3.
pDriverInfo
Points to either a DRIVER_INFO_1, DRIVER_INFO_2, or DRIVER_INFO_3structure. If Level is 1, this array receives a DRIVER_INFO_1 structure; if Level is 2, this array receives a DRIVER_INFO_2 structure, if Level is 3, this array receives a DRIVER_INFO_3 structure.
cbBuf
Specifies the size, in bytes, of the array at which pDriverInfo points.
pcbNeeded
Points to a value that specifies the number of bytes copied if the function
succeeds or the number of bytes required if cbBuf is too small.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The printer handle identified by the hPrinter parameter should be retrieved by calling the OpenPrinter function.
The DRIVER_INFO_2 and DRIVER_INFO_3 structures contain a full path and filename specifying the location of the
printer driver. An application can use the path and filename to load a printer
driver by calling the LoadLibrary function and supplying the path and filename as the single argument.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
