Hey
I've just been checking out Visual C++ 6.0, and was wondering how can i add,subtract etc, numbers which are inputed into edit boxes,
e.g. i have 4 edit boxes, box1=number1,box2=number2, box3=add,subtract..etc, and box 4 is the sum of number1&number2.
So when the user has inputed the values, he can then click a button which will calculate the value and display it in editbox 4.
how could i go about doing this?

Well, the process is simple:

1) You get the user input from these edit boxes and validate the data.
2) You then convert that text input into a suitable number.
3) You perform your mathematical operations on those numbers.
4) You then display the results.


BTW: This is not really a C++ language question and is off-topic here.

simple approach:
Assign numeric variables to the editboxes 1,2 and 4 (long, double) with the ClassWizard (Ctrl+W) and a string var to editbox 3.

After calling
UpdateData (TRUE)
you can use
your variables. Depending on the value of var3 you add, subtract etc var1 and var2 and store the result in var4
A call to
UpdateData (FALSE) puts the result of var4 into editbox.
