1. BUG:

     In vfp9, the Page Setup Dialog Box has no the Printer button on Windows Vista or later.

     There is no the bug in vfp6, vfp7 and vfp8.

     Please refer to the picture pagesetup9.jpg:

2. CAUSE:

     In vfp6, vfp7 and vfp8, it call the PrintDlgA Windows API to show the Page Setup Dialog Box.

     In vfp9, it call the PageSetupDlgA Windows API to show the Page Setup Dialog Box.
     But for some about security reasons, the Printer button has been removed on Windows Vista or later.


3. RESOLUTION:

     We can write some code to fix the BUG.

     vfpa_pagesetupdlga proc

     push ebp
     mov ebp,esp
     sub esp,48h
     push eax
     push ebx
     push ecx
     push edx
     push esi
     push edi
     pushfd

     mov esi,dword ptr [ebp+08h]
     lea edi,dword ptr [ebp-48h]
     xor eax,eax
     cld
     movsd
     sub dword ptr [edi-4],(54h-42h)

     movsd
     movsd
     movsd

     stosd

     movsd
     ; PD_PRINTSETUP (0x00000040) + PD_ENABLESETUPTEMPLATE (0x00008000)
     mov dword ptr [edi-4],00000040h+00008000h

     stosw
     stosw
     stosw
     stosw
     stosw
     add esi,4*2+4*4+4*4

     movsd
     mov dword ptr [edi-4],00400000h
     movsd

     stosd
     movsd
     add esi,4

     stosd
     movsd
     mov dword ptr [edi-4],0616h

     stosd
     movsd

     lea eax,dword ptr [ebp-48h]
     push eax
     call PrintDlgA

     mov dword ptr [ebp-04h],eax

     lea esi,dword ptr [ebp-48h]
     mov edi,dword ptr [ebp+08h]
     xor eax,eax
     cld
     movsd
     add dword ptr [edi-4],(54h-42h)

     movsd
     movsd
     movsd

     add esi,4

     movsd
     ; PSD_DISABLEMARGINS (0x00000010)
     mov dword ptr [edi-4],00000010h

     add esi,2*5
     add edi,4*2+4*4+4*4

     movsd
     movsd

     add esi,4
     movsd
     add edi,4

     add esi,4
     movsd

     add esi,4
     movsd

     popfd
     pop edi
     pop esi
     pop edx
     pop ecx
     pop ebx
     pop eax
     mov eax,dword ptr [ebp-04h]
     mov esp,ebp
     pop ebp
     ret 04h

     vfpa_pagesetupdlga endp

     We can use the vfpa_pagesetupdlga() function instead of the PageSetupDlgA Windows API,
     then the Page Setup Dialog Box will show the Printer and Properties buttons.
