<![CDATA[printER]]>hi,
hab n problem mit sonem tutorial, der zeigt mir imma nen Fehler bei "printER", kann mir einer weiter helfen??? man muss ne windows application machn und "winspool.lib" mitlinken πŸ‘

#include <windows.h>

HDC GetprinterDC (void) ;

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpszCmdLine, int iCmdShow)

if (hdcprint != NULL)
{
if (StartDoc (hdcprint, &di) > 0)
if (StartPage (hdcprint) > 0 && EndPage (hdcprint) > 0)
EndDoc (hdcprint) ;

DeleteDC (hdcprint) ;
}

return 0 ;
}

HDC GetprinterDC (void)
{
DWORD dwNeeded, dwReturned ;
HDC hdc ;

printER_INFO_5 * pinfo5 ;

und das immer da wo was mit "printER" steht

Somit musst Du die Namen der Funktionen genau so schreiben wie sie deklariert sind und (i.d.R.) auch in der Hilfe stehen!

EnumPrinters

bei

hdc = CreateDC (NULL, pinfo5->pprinterName, NULL, NULL) ;

meint der: 'struct_PRINTER_INFO_5A'has no member named 'pprinterName'
