Safe Programming

Once doing Code Review I found a code snippet like this and so thought would share my experience here.

CDialog *SomeDialog = new CMyDialog(<<Some Param>>);
SomeDialog->SomeFunction(this);

In the above code we always assume that SomeDialog is always allocated with the CMyDialog class pointer but that may not be the case always and so its always better to have the code as follows.

CDialog *SomeDialog = new CMyDialog(<<Some Param>>);
if(SomeDialog != NULL)
{
    SomeDialog->SomeFunction(this);
}

and it would always make your programming effort safer and subject to less crashes.
