How do I take the value from a textbox (or a field) and put it into a "double" variable? Do I have to convert the value somehow beforhand? I'm using VC6 and am using the GraphApp programming library.
GetDlgItemText()
and then use the string in an atof() call.
Which header(s) do I need?
uh...
windows.h?
What is the GraphApp library?
