EnumPrinterDrivers
The EnumPrinterDrivers function enumerates all of the printer drivers installed on the specified
printer server.
BOOL EnumPrinterDrivers(
LPTSTR pName,
| // pointer to server name
| LPTSTR pEnvironment,
| // pointer to environment name
| DWORD Level,
| // structure level
| LPBYTE pDriverInfo,
| // pointer to an array of structures
| DWORD cbBuf,
| // size, in bytes, of array
| LPDWORD pcbNeeded,
| // pointer to number of bytes copied (or required)
| LPDWORD pcReturned
| // pointer to number of DRIVER_INFO. structures
| );
|
|
Parameters
pName
Pointer to a null-terminated string that specifies the name of the server on
which the printer drivers should be enumerated.
If pName is NULL, the function enumerates the local machine's printer drivers.
pEnvironment
Pointer 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 function uses the current environment of
the caller/client (not of the destination/server).
Level
Specifies the type of structures pointed to by pDriverInfo. This value must be 1, 2, or 3.
pDriverInfo
Pointer to a buffer that receives an array of DRIVER_INFO_1, DRIVER_INFO_2, or DRIVER_INFO_3 structures. Each structure contains data that describes an available printer
driver.
cbBuf
Specifies the size, in bytes, of the buffer pointed to by pDriverInfo.
pcbNeeded
Pointer to a value that the function sets to the size in bytes of the data
that enumerates the printer drivers. If cbBuf is smaller than this value, EnumPrinterDrivers fails, and the variable pointed to by pcbNeeded represents the required buffer size. If cbBuf is equal to or greater than this value, the variable pointed to by pcbNeeded represents the number of bytes stored into the buffer.
pcReturned
Pointer to a value that specifies the number of structures that it stores into
the buffer pointed to by pDriverInfo. This is the number of printer drivers installed on the specified print
server.
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.

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 » |
