C, C++, Java, VB, and I won't mention the other 3 completely obsolete languages i know. Java is possibly my strongest, dealing with abstraction, inheritence and all that fun stuff that goes along with it.
I have professional experience on the following:
VB6 (Win32/MFC Calls)
VB and C#.net (using it on ASP.Net),
and Java (j2me, j2ee, servlets, spring framework, hibernate, applet, webwork)
SAS (Base and Macro Programming)
