How to convert CString to int MFC 7.1

[Greg Ellis]

Hi Guys, I am trying to convert a CString to an int in an MFC 7.1 unicode project, but it wont work. Here is what I tried. CString cszNumber = "1234567"; int nNumber = atoi(cszNumber); That didn't compile so I tried this CString cszNumber = "1234567"; int nNumber = _ttoi(cszNumber.GetBuffer(0)); That only brought across the first digit. Any Ideas? This method used to work fine in my old non unicode MFC 6 project. Cheers, Greg

Here's one way. Be sure to check the return status of sscanf_s().

int nNumber = 0;
CString strNumber = "1234567";
sscanf_s (strNumber, "%d", &nNumber);

_ttoi should work without the GetBuffer call, I believe.

Why use scanf? I always prefer to use strtol to accomplish this task. I personally hate scanf so I was wondering why you would recommend it.

(s)scanf() is deterministic - strtol() isn't. Nor is _ttoi() as suggested by CG. /ravi

And one more thing when use of GetBuffer use of ReleaseBuffer ;)

Or you could use the "Generic-Text Routine Mappings" These will work on both Unicode and non-Unicode builds. CString cszNumber = _T("1234567"); int nNumber = _tstoi(cszNumber);
