I use BCB and OLE object "Excel.Application" to open an existing Excel file.
Could I open this existing excel file and set it to be read only through OleProcedure or OleFunction directly?
By the moment, my code is:   Workbook=Workbooks.OleFunction("open", "c:\\test.xls");
it will open an Existing file and could modify data.
I know FileSetAttr Function may make it? But I hope open an file by OleProcedure and set it ReadOnly directly..

There is no need to do it through OLE.
You can use "FileSetAttr".
extern PACKAGE int __fastcall FileSetAttr(const AnsiString FileName, int Attr);
Internal help will guide you.

Thank you! I know FileSetAttr may do it just I mentioned before. But I wonder Does OLE procedure can do it only change some parameter? If so, I don't need to use FileSetAttr.

My opinion is that when you can use native borland calls it is better to do it that way...
Right now I'm working with OLE with Internet explorer and its hell to try 2 find my way due 2 error messages when I link Microsoft's headers.

I read MSDN for opening Excel like the following paragraph:
Sub OpenUp()
    Workbooks.Open("C:\MyFolder\MyBook.xls")
End Sub
and
expression.Open(FileName, UpdateLinks, ReadOnly, Format, Password, WriteResPassword, IgnoreReadOnlyRecommended, Origin, Delimiter, Editable, Notify, Converter, AddToMRU)
How do write in BCB

Suppose you have pro or enterprise version >= 5 of BCB.
At the servers page of objects there is ExcelAplication.
The help file (must download as office97 help file) gives explaination on how it is wrapped and how you can work with them...
It will be better if you use the VCL rather than MFC.
To tell the truth for myself I didn't find a way myself YET but I hope in a few days I will.
