如何检测WinCE运行平台

            if (lstrcmp(szPlatform,TEXT("PocketPC"))==0)
                iDeviceType= POCKETPCV1; // runs on Pocket PC 2000 and 2002
            else if (lstrcmp(szPlatform,TEXT("Smartphone"))==0)
                iDeviceType= SMARTPHONEV1; // runs on Smartphone 2002
        }    
        else
        { 
            if (GetLastError()==ERROR_ACCESS_DENIED)    //(5)
                iDeviceType= SMARTPHONEV1;       // is a smartphone:
            // Smartphone creates an access denied error on
            // SystemParametersInfo() 
        }
    }
    else
    {
        if (osVer.dwMajorVersion==4)
        { 
            if (SystemParametersInfo(SPI_GETPLATFORMTYPE, sizeof(szPlatform), szPlatform,0)!=0)
            {
                if (lstrcmp(szPlatform,TEXT("PocketPC"))==0)
                    iDeviceType= POCKETPCV2;       // runs on Pocket PC 2003
                else if (lstrcmp(szPlatform,TEXT("Smartphone"))==0)
                    iDeviceType= SMARTPHONEV2;       // runs on Smartphone 2003
            }    
            else
            { 
                if (GetLastError()==ERROR_ACCESS_DENIED) //(5)
                    iDeviceType= SMARTPHONEV2;          // is a smartphone:
                // Smartphone creates an access denied error on
                // SystemParametersInfo() 
            }
        }
    }
    return iDeviceType;
}

在 Smartphone 上，调用“SystemParametersInfo()”可能会因“Access Denied”而失败，这取决于 Smartphone 是否锁定和应用程序签署的证书。
