hi, I'm an MCAD developing WinApps. I would like to become MCPD WinApps, vb or maybe c#, don't know yet. I did MCAD using Que Publishing books, which were an excellent preparation for me. Does anyone has info about good prep books ? On the M$ site I saw several books for this upgrade, but are they alle necessary, don't think so. M$ books are not the best preparation also. I went looking the Que website, but didn't find a 70-552 book. Does anyone has other links ? Suggestions ? Thanks! Tafkas MCAD.net
