VC++ 6.0 and DX8.0 application compilation problem.

[lucky6969b]

I need to re-compile an old DX8 application. Temp I don't want to recode it.
So I compile it in my XP VM with VC++ 6.0.

I got this

C:\DXSDK\samples\Multimedia\common\src\d3dapp.cpp(1308) : error C2664: 'DialogBoxParamA' : cannot convert parameter 4 from 'long (struct HWND__ *,unsigned int,unsigned int,long)' to 'int (__stdcall *)(struct HWND__ *,unsigned int,unsigned int,long)'
        None of the functions with this name in scope match the target type

How can it be fixed?
Thank you very much
Jack

Could you show how you call this function and what parameters pass in it?

static INT_PTR CALLBACK SelectDeviceProc( HWND hDlg, UINT msg, 
                WPARAM wParam, LPARAM lParam );

typedef long INT_PTR, *PINT_PTR;


// Prompt the user to change the mode
    if( IDOK != DialogBoxParam( (HINSTANCE)GetModuleHandle(NULL),
                                MAKEINTRESOURCE(IDD_SELECTDEVICE), m_hWnd,
                                SelectDeviceProc, (LPARAM)this ) )

Why do you redefine INT_PTR?
By design of Microsoft it is mapped to int on 32-bit platforms, not to long!
You have to remove your typedef (or, at least correct it)

Hi Victor,
I did not redefine it. It was contained inside the application framework of DirectX 8.1 SDK.
Thanks
