Convert CString to int

[Matthias Pospiech]

I have the simple problem to do something like

CString PhaseText;
m_WndEditPhase.GetWindowTextW(PhaseText);
int phase = ConvertCStringToInt(PhaseText);

but I do not know how the ConvertCStringToInt should look like in real code.

atoi(PhaseText.GetBuffer(0));
does not work because of conversion problems and seems to be C-code.

Solution ?

Use _tcstoi to have support in both unicode and non-unicode environments.
But this will not solve your problem. You should do smth like this;
int n = _tcstoi(PhaseText, NULL, 10); // 10 is base

Or an object-oriented approach;
#include <sstream>
std::stringstream ss;
ss << PhaseText;
int n;
ss >> n;

Matthias:

int phase = _ttoi(PhaseText);

_ttoi. No need for GetBuffer at all.

CString s;
...GetWindowText(s);
int n = _ttoi(s);
