我们可以使用Windows CE里支持的 GetVersionEx 函数和 OSVERSIONINFO 结构体实现对平台版本的检测如下面的代码：

#define DESKTOPID  500

#define SMARTPHONE2003ID  403

#define SMARTPHONE2002ID  402

#define POCKETPC2003ID  303

#define POCKETPC2002ID  302

#define POCKETPC2000ID  300

#define OTHERWINCEID  100

#define UNKNOWNID  0

BOOL rb;

int rc;

int iDevice = 0; 

OSVERSIONINFO osvi;

TCHAR szPlatform[MAX_PATH];
 

osvi.dwOSVersionInfoSize = sizeof(osvi);

rb = GetVersionEx(&osvi);

if (rb == FALSE)  // GetVersionEx failed.

{
    rc = MessageBox(NULL, _T("Could not create main window."),

                    _T("Error"), MB_OK);

    if (rc == 0) 

        return E_OUTOFMEMORY;

    return E_FAIL;  // Replace with specific error handling.

}

switch (osvi.dwPlatformId)

{

    // A Windows CE platform.

    case VER_PLATFORM_WIN32_CE:

        // Get platform string.

        rb = SystemParametersInfo(SPI_GETPLATFORMTYPE,

                                  MAX_PATH, szPlatform, 0);

        if (rb == FALSE)  // SystemParametersInfo failed.

        {

            rc = MessageBox(NULL, _T("Could not create main window."),

                            _T("Error"), MB_OK);

            if (rc == 0)  // Not enough memory to create MessageBox.

                return E_OUTOFMEMORY;

            return E_FAIL;  // Replace with specific error handling.

        }

        else  // SystemParametersInfo succeeded.

        {

            if (0 == lstrcmpi(szPlatform, TEXT("Smartphone"))) 

            {  // Smartphone devices.

                if (osvi.dwMajorVersion == 3)

                    iDevice = SMARTPHONE2002ID;

                else if (osvi.dwMajorVersion == 4)

                    iDevice = SMARTPHONE2003ID;

                else  // Unknown device.

                    iDevice = UNKNOWNID;

            }

            else if (0 == lstrcmp(szPlatform, TEXT("PocketPC")))

            {  // Pocket PC devices.

                if (osvi.dwMajorVersion == 3)

                    if (osvi.dwMinorVersion == 0)

                        iDevice = POCKETPC2000ID;

                    else if (osvi.dwMinorVersion == 1)

                        iDevice = POCKETPC2002ID;

                    else  // Unknown device.

                        iDevice = UNKNOWNID;

                else if (osvi.dwMajorVersion == 4)

                    iDevice = POCKETPC2003ID;

                else  // Unknown device.

                    iDevice = UNKNOWNID;

            }

            else

            {  // Some other Windows CE–based device.

                iDevice = OTHERWINCEID;

            }

        }  // SystemParametersInfo succeeded.

        break;

    // A desktop Windows platform.

    default:

        iDevice = DESKTOPID;

    break;
}
