What exactly are you having trouble with? Are you getting compiler errors and/or warnings? Is the code not working as expect (and if so, how)?

The code you posted is C, did you mean to post on the C++ board?

it is c# but i compile it in c++. i have compiler errors. but i have no idea how to fix them.

C# and C++ are completely different languages. This looks like cobbled-together C code from various sources with a few errors sprinkled in.

How about you post your error messages.
