有关C++的问题

[yibo2010]

刚开始学C++ 有段代码 不知道那里写错了 谁能帮我解决



extern CDriverTestApp theApp;

CString strText(_T(""));;
GetDlgItemText(IDC_BUTTON_GetBatteryLevel, strText);
INT level = theApp.GetBatteryLevel();
int val2 = _ttoi(level);
SetDlgItemText(IDC_STATIC_GetBatteryLevel,val2);

[xiaohuh421]

SetDlgItemText(IDC_STATIC_GetBatteryLevel,val2);//这里第二个参数要是一个LPCSTR吧,即一个字符串指针,你却传了一个整形值.

那该怎么弄 ？

[kbh1984]

CString str;
str.Format("%d",val2);
SetDlgItemText(IDC_STATIC_GetBatteryLevel,str);

CString::Format()

[yibo2010]

好像还不行

[yby4769250]

INT level = theApp.GetBatteryLevel();
int val2 = _ttoi(level);
这两句哪句什么是什么啊？
INT level = theApp.GetBatteryLevel();
CString str;
str.Format("%d",level);
SetDlgItemText(IDC_STATIC_GetBatteryLevel,str);

[yby4769250]

或者用void SetDlgItemInt( int nID, UINT nValue, BOOL bSigned = TRUE );
