还是继续上一篇Unicode的问题，各种LPTSTR，LPCTSTR问题

终于明白Unicode下整型数与字符串，CString 转换例程如下：（vs2005）

//////////good code from CSDN
//int num1,num2,num3;
// WCHAR ch1[10],ch2[10],ch3[10]; //WCHR
//

// GetDlgItem(IDC_EDIT1)->GetWindowText(ch1,10);
// GetDlgItem(IDC_EDIT2)->GetWindowText(ch2,10);

//   num1=_wtoi(ch1); //_wtoi
//   num2=_wtoi(ch2);
//   num3=num1+num2;

// _itow(num3,ch3,10); //_itow

// GetDlgItem(IDC_EDIT3)->SetWindowText((LPTSTR)ch3);

//good code from CSDN
  /*int num1,num2,num3;
    TCHAR ch1[10],ch2[10],ch3[10];
    GetDlgItem(IDC_EDIT1)->GetWindowText(ch1,10);
    GetDlgItem(IDC_EDIT2)->GetWindowText(ch2,10);

    num1=_ttoi(ch1);
    num2=_ttoi(ch2);
    num3=num1+num2;

_itot(num3,ch3,10);

GetDlgItem(IDC_EDIT3)->SetWindowText(ch3);*/

/////////good code From CSDN

// int num1,num2,num3;
//CString str1, str2, str3;
//GetDlgItem(IDC_EDIT1)->GetWindowText(str1);
//GetDlgItem(IDC_EDIT2)->GetWindowText(str2);
//
//num1=_ttoi((LPCTSTR)str1);
//num2=_ttoi((LPCTSTR)str2);
//num3=num1+num2;
//
//_itot(num3,(TCHAR*)str3.GetBuffer(10),10);
//str3.ReleaseBuffer();
//
//GetDlgItem(IDC_EDIT3)->SetWindowText(str3);

//当调用GetDlgItemText（）时上述三种情况如下

//int num1,num2,num3;
//TCHAR ch1[10],ch2[10],ch3[10];
//GetDlgItemText(IDC_EDIT1,ch1,10);
//GetDlgItemText(IDC_EDIT2,ch2,10);
//num1=_ttoi(ch1);
//num2=_ttoi(ch2);
//num3=num1+num2;
//_itot(num3,ch3,10);

//SetDlgItemText(IDC_EDIT3,ch3);

//int num1,num2,num3;
//WCHAR ch1[10],ch2[10],ch3[10];
//GetDlgItemText(IDC_EDIT1,ch1,10);
//GetDlgItemText(IDC_EDIT2,ch2,10);
//num1=_wtoi(ch1);
//num2=_wtoi(ch2);
//num3=num1+num2;
//_itow(num3,ch3,10);

//SetDlgItemText(IDC_EDIT3,ch3);
int num1,num2,num3;
CString str1,str2,str3;
GetDlgItemText(IDC_EDIT1,(LPTSTR)str1.GetBuffer(10),10);
GetDlgItemText(IDC_EDIT2,(LPTSTR)str2.GetBuffer(10),10);
num1=_ttoi((LPTSTR)str1.GetBuffer(10));
num2=_ttoi((LPTSTR)str2.GetBuffer(10));
num3=num1+num2;
_itot(num3,(TCHAR*)str3.GetBuffer(10),10);
str3.ReleaseBuffer();

SetDlgItemText(IDC_EDIT3,str3);
