Want to get a Value

[Hasch2o]

Hello Everybody,

my problem is that I want to make a window, where a user can put information.
After that I want to calculate with this information, the information-variable
is a double. I got the Program as a Console-file, but I want to do it with the
MFC Appwizard.
I have no Idea if anyone understands what im writing here, but if so, Pleae help

Hi,
in asking questions like this it's highly recommnded that you tell about your knowledge of C, C++, VISUAL C++ !
windows programs work quite different then console (maybe DOS) programs, in inputting data as well as in outputting !

Hi Fheyn

All Right then:

I'm in a Apprenticeship and I started with c++ in school 3 months ago. Visual C++ is just something I do for fun, more or less. Now I started to do a win32 console apllication which allows me to bring out the 2 solutions of ax^2*bx*c=0 . This worked really well and I had no Problems with that. And now I want to do the same with Visual C++. But I've got no great Idea, so I'm just trying.
But now I've got the problem that I started with the Appwizard and I've got the DIALOG like I wanted. but now I want that I can get the Value (a,b,c) from the equation i've written allready. But I don't know how I can get these Values for calculations I Have to do.

I hope it is written a little bit more understandable.

OK
Here is what you do :
you'll create three edit-controls for inputting your values a, b, c. Use Class-Wizard to create a member variable for
each control.
Create a button-control which will start your calculation.
On the buttons click-event call your calculation-function.
create an edit-control with member variable for showing the functions result.
Try it out ! it's fairly easy.
And don't forget : UpdateData(TRUE) writes the control-value
(that's what you see) to the associated member-variable.
UpdateData(FALSE) updates your control (if the member-variables value has changed).

Include it in your dialogs headerfile.
and it's math.h
