SCard Transmit response = '6700'

Hi Oliver,
I'm checking the GemCard project for card reader OMNIKEY 3121.
After successful connecting the first APDU command (SELECT APPLICATION) returned with 0x6700 status.

I attempted to test it in two environments, with the same result.
I could not find the explanation of this error (invalid length?), probably can you help me?..

1. environment:
Windows XP, VS2003, .NET 1.1, 32 bit
2. environment:
Windows 7, VS2010, .NET 2.0 32 bit

Test code:

static APDUCommand apduSelectApp = new APDUCommand(0x00, 0xA4, 0x04, 0, null, 0);
    ...
    try
    {
        APDUResponse apduResp;
        CardNative iCard = new CardNative();

        // get driver name
        string[] readers = iCard.ListReaders();

        // Check existing of card reader
        if (readers == null || readers.Length == 0)
            throw new Exception("No smart card reader found!");

        // Connect to the card
        iCard.Connect(readers[0], SHARE.Shared, PROTOCOL.T0orT1);
        Console.WriteLine("Connects card on reader: " + readers[0]);

        // Select the single application
        byte[] ba = Utils.HexStringToByteArray("A0000000043060");
        APDUParam apduParam = new APDUParam();
        apduParam.Data = ba;
        apduParam.Le = 0x00; // or 0xFE, the same result...
        apduSelectApp.Update(apduParam);
        apduResp = iCard.Transmit(apduSelectApp);
        // here I get the error status...

The console output (debug):

Connects card on reader: OMNIKEY CardMan 3x21 0
APDU Buffer  : 00A4040007A0000000043060
APDU Response: 6700
Maestro (Debit) read, SW=6700

Note, that this card was successfully processed (select application, read record, etc.) by Smart Card Console (Java application).

Thank you in advance,

Serge
