Conversion matter

Hi
I ve got an issue with my calculator programme. The calculator is not in cosole but in window by the way.

Anyway I do not know how to get the value which is typed in the display window so the computer understands the number and is able to work with it.

The instruction I am looking for is some kind of

Code:

---

GetWindowText()

---

of course some instruction which works for ints...

Or another choice could be to convert the number from string to an int?

Code:

---

wsprintf()

---

of course this does not work in way from string to int.
Do you have any ideas how to solve this?

In general the only problem is that I am not able to get the displayed number as an int but as a string which does not work so well for calculator does it?

Alternatively you can get it as a string, and then call atoi(), or perhaps more preferably strtol().
