I’ve changed DSixfer.
Before:
private static extern eTwRC DSixfer( [In, Out] cTwIdentity origin, [In] cTwIdentity dest, eTwDG dg, eTwDAT dat, eTwMSG msg, ref IntPtr hbitmap );

After
private static extern eTwCC DSixfer( [In, Out] cTwIdentity origin, [In] cTwIdentity dest, eTwDG dg, eTwDAT dat, eTwMSG msg, ref IntPtr hbitmap );

eTwRC -> eTwCC

And now first:
cc = DSixfer(m_appID, m_srcDS, eTwDG.Image, eTwDAT.ImageNativeXfer, eTwMSG.Get, ref hbitmap);

cc = eTwCC.BadCap

Second:
cc = DSixfer(m_appID, m_srcDS, eTwDG.Image, eTwDAT.ImageNativeXfer, eTwMSG.Get, ref hbitmap2);

cc = eTwRC.Bummer
