error opening excel sheet in c#

Dec 6th, 2008

i'm trying to open an existing excel worksheet. my code is:

 Help with Code Tags 
 c# Syntax (Toggle Plain Text) 
Microsoft.Office.Interop.Excel.Application excelApp;
Microsoft.Office.Interop.Excel.Workbook excelWorkbook;
Microsoft.Office.Interop.Excel.Worksheet ExlWrkSheet;
private object Opt = Type.Missing
 
excelApp = new ApplicationClass();
 
excelWorkbook = excelApp.Workbooks.Open("..//..//Data.xls", Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt);
Microsoft.Office.Interop.Excel.Application excelApp;
Microsoft.Office.Interop.Excel.Workbook excelWorkbook;
Microsoft.Office.Interop.Excel.Worksheet ExlWrkSheet;
private object Opt = Type.Missing

excelApp = new ApplicationClass();

excelWorkbook = excelApp.Workbooks.Open("..//..//Data.xls", Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt);

on the last line i get an exception that he cannot find the file.
i placed the file in the project directory.
i tried also "Data.exl" path when the file is placed in the debug directory, it didn't helped.

Why not use a pathname like @"C:\....\Test.xls" ?

i tried it with an absolute path like "c:\Data.xls" and it works fine.
the problem is with relative path.

Read this http://weblogs.asp.net/pwelter34/arc...e-snippet.aspx
it might help.
It is also possible that Open only accepts absolute paths.

Open does except relative paths, however, you have to be sure of where you are vs where your file is which is often unlikely.

So, if you have your app, and you are sure you are in your exe's directory, then opening "Data/file" will work - but, for example, excel may not be in the apps directory but its own, you can tell by using the filemonitor from microsoft (seeing as they bought the company out) which will show you where it was trying to find the file.

Did I just hear "You gotta help us, Doc. We've tried nothin' and we're all out of ideas" ? Is this you? Dont let this be you! I will put in as much effort as you seem to.
