【MFC】MFC文本框中显示浮点数

CString strNumber;

strNumber.Format("%0.2f",tim.getTimeMilli());

SetDlgItemText(IDC_TIME_USED,strNumber);

 error C2664: 'voidATL::CStringT::Format(const wchar_t *,...)' : cannot convertparameter 1 from 'const char [6]' to 'const wchar_t *'

解决方法：

采用了UNICODE编码， 

可以用 

a.Format(L "%d ",  b); 

或者 

a.Format(_T( "%d "),   b);

即：strNumber.Format(_T("%.2f "), tim.getTimeMilli());

OK！
