How do diffrent reconnection

[setur]

Hi.
I need to modify source code for that thing: vnc client show one server, after 30 sec client close connection and open connection to another server from list.
I'm so bad in uvnc source and Win C programming and so i need help.

I'm see 2 ways.

Modify App object and WinMain functtion. First App object shows one server. After 30 sec it sends a special message and kill itself. WinMain msg cycle recives a message and create new app object.

Or modifing clientconnection object. But i don't understand how it works. I tried to use this:
_this->KillThread();
_this->DoConnection();
but it doesn't work.

Please help me with an advice and describing of the clientconnection Run DoConnection KIllTherad and other functions.

[setur]

I have a progress with that.
But I have a new problem.

///Force break after timeout
DWORD threadID;
ThreadSocketTimeout = CreateThread(NULL,0,SocketTimeout,(LPVOID)&m_sock,0,&threadID);
res = connect(m_sock, (LPSOCKADDR) &thataddr, sizeof(thataddr));

This socket timeout doesn't work and i don't know why.
