一个关于文件读取的问题

[rinoe]

文件——》打开——》弹出对话选择对话框后，

代码要怎么写才可以完成以下功能：

文件选定判断，文件读取后显示在edit box控件内

CString strText;
strText = "Text Files(*.dat)|*.dat|All Filse(*.*)|*.*||";
CFileDialog dlgfileopen(true,"dat",NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,strText);
int structsize =0;
DWORD dwVersion,dwWindowsMAjorVersion,dwWindowsMinorVersion;
dwVersion =GetVersion();
dwWindowsMAjorVersion =(DWORD)(LOBYTE(LOWORD(dwVersion)));
dwWindowsMinorVersion =(DWORD)(HIBYTE(LOWORD(dwVersion)));
if(dwVersion<0x80000000)
structsize =88;
else
structsize =76;
dlgfileopen.m_ofn.lStructSize =structsize;
TCHAR lpstrFilename[MAX_PATH] ="";
dlgfileopen.m_ofn.lpstrFile =lpstrFilename;
if(dlgfileopen.DoModal()==IDOK)
{

CString filename;
filename =dlgfileopen.GetPathName();
CFile myfile;
CString m_disp;
myfile.Open("filename",CFile::modeRead);
myfile.SeekToBegin();
myfile.Read(m_disp.GetBufferSetLength(myfile.GetLength()),myfile.GetLength());
GetDlgItem(IDC_EDIT1)->SetWindowText(m_disp);//在文本框中显示




}

else
MessageBox("dasdsadsa");

}


不知道怎么出错了的啊！
想不到！

大家支持我一下！

还是稍微的回一下才好的啊！

[stoone]

看不出来，提示的什么错误阿

[ghxmagic]

CFile::modeRead
->
CFile::modeRead | CFile::shareDenyWrite

[rinoe]

怎么会说，“没有找到一未命名文件”

这到底是怎么一回事啊！

现在非常郁闷！

[cngonet]

dlgfileopen.m_ofn.lStructSize =structsize;
TCHAR lpstrFilename[MAX_PATH] ="";
dlgfileopen.m_ofn.lpstrFile =lpstrFilename;

m_ofn是你字加的成员变量吗？如果是要说一下啊

把问题说清楚。。。
