Im getting a stack over flow execption its not from an ASSERT but storage on my stack frame is corrupted. I have a thread Waitting on event to be notified when a socket read is pending

I trace socket number upon entry and its ok I initialize a WSABUF which 15 entires and its fine somewhere when I do the WaitforSingleObject the stack frame gets corrupted

I did a data break point on the socket and its was somewhere in UserCallwinprocccheckwow.

best to post my code some where in the WaiforSingleObject sonething happens to my stack frame

here is the code for notification
int ret1 = WSAEventSelect(mysocket, socksevent, FD_READ | FD_CLOSE);

here is the createthread

struct threadparm thethreads;
thethreads.thesocket = mysocket;
thethreads.sendwidow = pFrame->m_hWnd;
thethreads.messge = WM_STORAGE;
thethreads.sockevent = socksevent;
struct threadparm* parmptr = &thethreads;

HANDLE threadhandle = ::CreateThread(NULL, 0, SocketThread, (LPVOID)parmptr, 0, &threadid);


the thread with Waitforsingleobect were somewhere threadptr->thesocket gets corrupted


DWORD WINAPI SocketThread(LPVOID lphadleparater)
{
WSANETWORKEVENTS socknetwork;
struct threadparm* threadptr;
threadptr = (threadparm *)lphadleparater;
WSABUF DataBuf[15];
DWORD recived;
int i, j;
DWORD flags = 0;
WSAOVERLAPPED myoverlap;
char* sendcopy = new char[3825];
char* holdptr = sendcopy;
j = 0;
for (i = 0; i < 15; i++)
{
DataBuf[i].buf = new char[255];
DataBuf[i].len = 255;
}
struct _WSABUF* tcpip = &DataBuf[0];

DWORD dwWaitStatus = WaitForSingleObject(threadptr->sockevent, INFINITE);
switch (dwWaitStatus)
		/* a read is pending */
	    	case WAIT_OBJECT_0 + 0:
	{
		int return_code = WSAEnumNetworkEvents(threadptr->thesocket, threadptr->sockevent, &socknetwork);
