Java has variable-length argument lists.

THREADPARAMS * pSocket;
pSocket->m_sServerSocket.Accept(m_sClientSocket);

pSocket is not initialized. You need to assign a valid value first.

for (j = 0; j < playerNum; j++)
{
for (k = (playerNum - 1); k > j; k--)
{
// j==k test not needed, k>j
...

Visual Basic
- easier to learn

C++
- better performance
- more game libraries available
- can be portable to other platforms

Look in MSDN for GetOpenFileName and SetSaveFileName functions.

System.out.println(Math.cos(Math.toRadians(90)));
System.out.println(Math.cos(Math.toRadians(270)));

gives

6.123233995736766E-17
-1.8369701987210297E-16

good enough for most purposes.

You have to use Music OCR techniques. Check http://www.musitek.com/ for a product doing something similar. For the xml to midi part you have to look for the file format or library for writing midi...

Look for "Win32 Binary (MSI Installer)", download, run setup program, fallow the setup instructions.

Computers can solve many math problems with the right algorithm and resources. It depends a lot on what kind of problems you want to solve and the available hardware.

Math.cos is using angles in radians. Try Math.cos(Math.toRadians(90)).

Second - I don't understand.

Try jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
