Hi Ehsan ,
Thanks for the below.
If for example I have a global class :
CExample List;
void CExample ::Increase()
{
m_Variable++; //this is variable declared in header
if(m_Variable==20)
AfxMessageBox("reached..");
}
void CExample ::SetValue(int Value)
{
m_Variable=Value;
}
The above is just an example, but if my main thread was accessing
Increase(), and the OnTimer() called Clear(), it seems possible for the
m_Variable to access the variable the during the Increase routine from my
main thread. I want to make sure only 1 function is accessed at a time,
Neil
