> cds=new COPYDATASTRUCT;

You do not need to create the COPYDATASTRUCT dynamically.  Use it on the
stack instead:

    COPYDATASTRUCT cds = {0};
    //...
    SendMessage(myHandle, WM_COPYDATA, 0, (LPARAM)&cds);

> pDS=(COPYDATASTRUCT*)(&buff);

You are casting the wrong thing.  It should be this instead:

    pDS = (COPYDATASTRUCT*)buff;

> memcpy(&tempbuffer, (unsigned short*)(pDS->lpData),100*sizeof(short));

You can simplify that to this:

    memcpy(tempbuffer, pDS->lpData, pDS->cbData);
