Question

大家好我正在开发一款适用于Windows 7的智能卡驱动程序但是在Windows 8.1上有时会弹出一个错误“智能卡需要驱动程序不在此系统上.Pl;轻松尝试另一个智能卡或联系您的管理员。“ 还有一点我注意到智能卡驱动程序的行为在win 8.1上也有所不同。为此，我写了一个简单的应用程序代码，我在下面提供win 7和Windows 8.1的驱动程序登录。

lReturn = SCardEstablishContext(SCARD_SCOPE_USER,
                             NULL,
                             NULL,
                             &hSC);
if ( SCARD_S_SUCCESS != lReturn )
    message("Failed SCardEstablishContext\n");
else
{
    message("context established\n");
    lReturn = SCardGetCardTypeProviderName(hSC,
                                       szCardName,
                                       SCARD_PROVIDER_CSP,
                                       (LPTSTR)&szProvider,
                                       &chProvider);
    if (SCARD_S_SUCCESS == lReturn)
    {
        BOOL fSts = TRUE;
        HCRYPTPROV hProv = NULL;
        message("successfully reads the provider name\n >> %S: \n",szProvider);
        //
        __try
        {
            // Acquire a Cryptographic operation context.
            fSts = CryptAcquireContext(&hProv,
                                    NULL,
                                    szProvider,
                                    PROV_RSA_FULL,
                                    0);
            if(!fSts)
            {
                message("crypt aquire context failed\n");
            }
         }
         __finally
         {
            if (CryptReleaseContext(hProv,0))
            {
                mesage("The handle has been released.\n");
            }
            else
            {
                message("The handle could not be released.\n");
            }

        }

        // Free memory allocated by SCardGetCardTypeProviderName.
        lReturn = SCardFreeMemory(hSC, szProvider);
    }

}

lReturn = SCardReleaseContext(hSC);
if(SCARD_S_SUCCESS != lReturn)
{
    printf("failed in release context");
}

如果我遗漏了什么，请告诉我

在Windows 8.1上，我收到错误＆＃34;智能卡需要此系统上没有的驱动程序＆＃34;
