save data as csv or excel
-
im using VC++6 MFC, i want to create and save some data out to a file such as a csv file or even better a excel file. I know of CFileDialog to bring up a save dialog but how do i pump out data in a csv or excel format thanks

have your data as comma seperated values each row seperated by newline adn then jsut give the file .csv extension. That's how I used to do it.
how did you write the data out thou, i see there is CArchive but doesnt appear to do much!!

To communicate with Excel, you can use its ODBC driver, or Excel automation.

CFileDialoghas nothing to do with how the data is saved. It is for filename selection only.

There must be at least dozen ways to write a file. I suppose if you want something MFC there is CFile or CStdioFile? Perhaps even this http://www.codeproject.com/file/stdiofileex.asp#xx1295590xx[^] if you want some unicode support.

im wanna go down the csv route. i am using the CArchive as follows CFile f; char strFilter[] = { "csv Files (*.csv)|*.csv|All Files (*.*)|*.*||" }; CFileDialog FileDlg(FALSE, ".csv", NULL, 0, strFilter); if( FileDlg.DoModal() == IDOK ) { f.Open(FileDlg.GetFileName(), CFile::modeCreate | CFile::modeWrite); CArchive ar(&f, CArchive::store); ar<< m_Make << m_Model << m_Year << m_Mileage << m_Owner; ar.Close(); } else return; f.Close(); the above is coming out in one cell with a rectangular box after each string how do i get ride of those retangular boxes and have a string in a seperate cell thanks

But what does it look like when viewed with Notepad? Try:
CStdioFile f;
...
ar << m_Make << ',' << m_Model << ',' << m_Year << ',' << m_Mileage << ',' << m_Owner << endl;

still get the boxes as seen below a,b,c,d,e

Which implies that
m_Make,m_Model,m_Year,m_Mileage, andm_Ownerhave an odd character in them. Yes?

CString m_Make="a"; CString m_Model ="b"; CString m_Year ="c"; CString m_Mileage ="d"; CString m_Owner="e"; for testing purposes i have them as above, so where is this box coming from!!!

Unicodedness of your program without writing the unicode-header? A decent file editor (as opposed to a CEdit-gone-application like notepad) like Ultraedit would show it.
