Answers and help about c# / c++ using Visual Studio 2010

Hi there! I am a student of C# / C++ and I am still learning how to code in this language. In fact I am already coding in another language but I decided now to learn c#/c++ syntaxes I know that we have a lot of forums and tutorial over the internet, however I would like to establish a communication with some professional who can answer my emails quickly with my doubts. Basically, I am not interested in coding Interface, just DLL and I have created one in Borland c++ 5.5.1, but it is not working properly, perhaps because of this language is too old , so I decided to move forward with VS2010 . So in the begin, I do not want just to fix this code,but understand the syntaxes as well and make my own questions, like difference between char and char*, useing std::xxx , etc. Please contact me via PMB and let me know your offer Thanks!
