I am trying to avoid the old atof function.

That's the wrong direction.

If you use sprintf to convert from string to double, please show me how.

double myValue = 23.2;
CMyDialog dlg;
dlg.m_myDouble = myValue;

Remove these from the Header File and put in a separate CPP File.

I can not do that. This is dll header file... I didn't see any dll headers files with cpp file.
