do you know how to recover these stream handles?
Use CloseHandle() on the handles returned by CreatePipe().

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.

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

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, and m_Owner have 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.

Does either of OPENFILENAME.nFileExtension or OPENFILENAME.lpstrDefExt help?

Ideally for a Save-As dlg output should know the ext type of the document to be saved.
what I feel is it is confusing to display a Save-As dialog with no default extension.
Take the eg of Winword. when you try to save the file, it provides finite set of extensions in the "Save-as TYpe" combobox.
Inshort User can either provide a file with ext or system should provide the ext type in the filter type parameter.
see eg of pdf file save-As dlg:
CString strFilter = _T("PDF Files (*.pdf)|*.pdf||");<br />
<br />
CFileDialog saveDlg(FALSE, _T("*.pdf"), "" , OFN_NOREADONLYRETURN | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, strFilter);<br />
if(IDOK == saveDlg.DoModal())<br />
{<br />
}<br />

Hi everybody!
I have some experience with C++ and Borland Builder, but I`m totally new to Visual C++. Im using Visual C++ 6.0.
I need to load an image into my program, this picture inside a rectangle. This pic will be a .jpg. I need to have the option to put the picture anywhere inside this rectangle, in any time. Then I have to send it to printer, but JUST THE RECTANGLE AREA, not the whole thing that`s displaying in my program frame. The printer should be able to print using the rectangle as if it was the page size.
I just need some help!
- what component should I use to display the pic, one that has the above characteristics?
- Am I able to put this component into a common dialog frame and still be able to select just a rectangle area from this dialog to send to printer? What are the stepes to do that or where can I find the right info about that? Or should I use a Document page from a Single Document MFC Project? In this case, how would I be able to put the pic inside it?
- Finally, how can I send this rectangle to print so the printing process act the way described above?
Im stucked with this problem for a few days now and I just cant find info... Thank you all!

Dear all,
I'm writing a small application that manages the Themes service using WMI.
Unfortunately I have problems with the parameters. The API documentation says that it is a string, but I wasn't able to find a solution.
ExecMethod returns : WBEM_E_INVALID_METHOD_PARAMETERS = 0x8004102f
I have realized that the parameter is not well formatted, but I'm not able to find any tip.
Notice that the same code querying for "Win32_Process" and calling "Create" using CommandLine as parameter and "notepad.exe" as value, runs correctly. To test it, it is enough to replace the strings text.
Thanks
Daniele

Enumerate links? What do you mean by this?
