Global variables / persistant variable between forms and classes
DataClass data;
data.strComPort = "COM1";
How do I have that variable keep it's value after the current form is closed? When I close the form, the value is wiped out, even though strComPort is a public member of a different class (DataClass).
So far, I've been writing to the registry to store variables, but that's not an acceptable solution for this project. I've tried what I can make sense of on the google results to no avail.
