This works for MBCS.

CString tempS;
GetDlgItem(IDC_FILE_NUMBER_EDIT)->GetWindowText(tempS);
CT2CA pszConvertedAnsiString (tempS);
std::string strStd (pszConvertedAnsiString);

This should work for Unicode with minimal modifications if at all necessary

CString tempS;
GetDlgItem(IDC_FILE_NUMBER_EDIT)->GetWindowText(tempS);
std::string s((LPCTSTR)tempS);

To check whether you are using Unicode or MBCS, go to Project Properties -> General -> Character Set
