saving text in a file?

[mpallavi]

Hi cedric i am giving here my code: .......................... CFile flCPhone; CStdioFile fl; char strFilter[] = { "Text Files (*.txt)|*.txt|" }; CFileDialog FileDlg(FALSE, ".txt", NULL, 0, strFilter); if( FileDlg.DoModal() == IDOK ) { if( flCPhone.Open(FileDlg.GetFileName(), CFile::modeCreate | CFile::modeWrite) == FALSE ) { return;} CArchive ar(&flCPhone, CArchive::store); ar<

hey friends .. i did it.. it was simple ................. CFile flCPhone; flCPhone.Open(FileDlg.GetFileName(), CFile::modeCreate | CFile::modeWrite); int len; len=strlen(m_strInput); flCPhone.Write(m_strInput,len); ..................... thanx for showing me the write track.. i was simply running behind CArchive.. (A beginner in vc++.. getting into it..) thanx pal

if you allow the user to choose the file name and position with File dialog, in your flCPhone.open() use FileDlg.GetPathName() instead FileDlg.GetFileName(). regards, Eli

Ouch... Sorry, I have mixed CFile with FILE* :~ But I think your question has already been answered ;)

Hi cedric its ok.. :) I wasn't using the member functions of CFile.. There is no function for appending text to a file..in CFile (..I suppose).. How do i go about it?

[Cedric Moonen]

Then you can use FILE* and open it in appending mode ("-a"). Take a look at fopen in the doc: FILE* pFile = fopen("YourFile.txt","a"); fwrite(.....); // This will append text at the end of the file

Take a look at CArchive's << operator. If the length of the CString object is >= 255 and < 0xfffe, an extra 0xff is written to the archive followed by the length of the CString object.

Insert a CR and/or LF character first.
