Nice talking to you.

BYTE *pbyCmd <code>= NULL</code>;   //Always allocate a default value,
                       // or directly assign a value
 
pbyCmd = new BYTE[byCount+1];    //why +1 ?
 
if (pbyCmd) {
    delete<code>[]</code> pbyCmd;
    <code>pbyCmd = NULL;</code>    //this is not done automatically by delete
                      // but you should do it for security, and if
                      // you want to be able to test if NULL or not
}

Thanks. After long time we met .

delete pbyCmd; //or<br />
delete[] pbyCmd;
