我刚自己写的CODING..
CFileDialog l_SampleDlg(TRUE,NULL,NULL,OFN_OVERWRITEPROMPT,"Text Files (*.txt)|*.txt|Comma Separated Values(*.csv)|*.csv||");
int iRet = l_SampleDlg.DoModal();
CString l_strFileName;
CString strText;

l_strFileName = l_SampleDlg.GetPathName();

CFile cSplitFile ;
while(!cSplitFile.Open(l_strFileName,CFile::shareDenyWrite))//打开文件
continue ;
int nFileLen = cSplitFile.GetLength();
LPTSTR lpText = strText.GetBuffer(nFileLen+1) ;

m_Input = lpText;
UpdateData(FALSE);

if(iRet == IDOK)
MessageBox(l_strFileName);
else
MessageBox("No File Selected!");
但是M_INPUT还是读不到TXT文件里面的文字,为何呢?a

m_Input = lpText;
UpdateData(FALSE);

这是我的读取文件方式,但具体不知道怎么搞?请帮忙下!
