CreateDefaultSettings

#include “BlackIceDEVMODE.h”

BlackIceDEVMODE* CreateDefaultSettings(LPTSTR szPrinterName)

Description

Returns a new DEVMODE structure from the specified printer driver by reading the values from the printer’s INI file and current default settings.  This function must be used in conjunction with ClearUserSettings.  Returned DEVMODE can be assigned to the printer as new settings by using SaveDefaultBlackIceDevmode and SaveBlackIceDevmode.  PLEASE NOTE: Memory used by the returned DEVMODE must be freed by the developer using GlobalFree

Parameters

LPTSTR szPrinterName     - Printer Name (string).

Return value

Pointer to the BlackIceDEVMODE structure retrieved from the printer’s INI file settings.

Programming Notes

One should call ReleaseBlackIceDEVMODE for all DEVMODE handles whether it is returned by LoadBlackIceDEVMODE or CreateDefaultSettings

Code Example

None

Using the BlackIceDEVMODE.dll with applications configured for “Multi-Byte Character Set” (ANSI)

The DEVMODE structure returned and used by the BlackIceDEVMODE.dll functions is always Unicode. Internally, the BlackIceDEVMODE.dll uses Unicode. The ANSI functions (functions with a name ending with ‘A’) in the DLL convert the string parameters to Unicode and call the Unicode version of the function, but the DEVMODE structure is kept Unicode for efficiency reasons and to prevent data loss. When passing a DEVMODE structure returned by one of the functions in BlackIceDEVMODE.dll to WinAPI functions, the Unicode version of the WinAPI functions must be used.  You can use the Unicode version of WinAPI functions even if your application is not compiled to Unicode, by appending a ‘W’ character to the end of the WinAPI function name. For example, to call the Unicode version of CreateDC , you can use the CreateDCW function. To convert the printer name or other strings to Unicode, you can use the MultiByteToWideChar WinAPI function.

Sample Code:

       charszPrinterName[256] = "Black Ice ColorPlus";

       WCHAR szPrinterNameUnicode[256];

       MultiByteToWideChar(CP_ACP, 0, szPrinterName, -1, szPrinterNameUnicode, 256);

       HANDLE hPrinter = NULL;

       PRINTER_DEFAULTSW pd = { NULL, NULL, PRINTER_ALL_ACCESS };

       if(OpenPrinterW(szPrinterNameUnicode, &hPrinter, &pd))

       {

              LPBlackIceDEVMODE lpDevMode = LoadBlackIceDEVMODE(szPrinterName);

              if (lpDevMode == NULL)

              {

                     ClosePrinter(hPrinter);

                     return FALSE;

              }

              // Setting TIFF Group 4, 1 bit output for example

              SetFileFormat(FFR_TIFF_G4, lpDevMode);   // FFR_TIFF_G4 = 7

              SetColorDepth(BITS_1, lpDevMode);        // BITS_1 = 0

              HDC hDC = CreateDCW(L"WINSPOOL", szPrinterNameUnicode, NULL, (DEVMODEW*)lpDevMode);

              if(hDC == NULL)

              {

                     ClosePrinter(hPrinter);

                     return FALSE;

              }
