using find in excel from C# code

Hi,

I am working to make an aplication that open an existing excel file, search 
for some text and notifies the result. Now, when I run it, before the excel 
file's opens  get this error: 

COMException Types mismatch (Exception HRESULT: 0x80020005 
(DISP_E_TYPEMISMATCH))

My code is:

object oMissing = System.Reflection.Missing.Value;

                Excel.ApplicationClass oExcel = new Excel.ApplicationClass();
                oExcel.Visible = true;
                Excel.Workbooks oBooks = oExcel.Workbooks;
                Excel._Workbook oBook = null;

                oBook = oBooks.Open(path, oMissing, oMissing,
                    oMissing, oMissing, oMissing, oMissing, oMissing, 
oMissing,
                    oMissing, oMissing, oMissing, oMissing, oMissing, 
oMissing);

                Object cad = Cadena.Text; 
                Object LookIn = "xlValues";
                Object LookAt = "xlWhole";

                Microsoft.Office.Interop.Excel.XlSearchDirection xlApp = new 
Microsoft.Office.Interop.Excel.XlSearchDirection();

                Object resultat = oBook.Sheets.Application.Cells.Find(cad, 
oMissing, LookIn, LookAt, oMissing, xlApp, oMissing, oMissing, 
oMissing).Activate();
                
                // Quit Excel and clean up.

                oBook.Close(false, oMissing, oMissing);
                
System.Runtime.InteropServices.Marshal.ReleaseComObject(oBook);
                oBook = null;
                
System.Runtime.InteropServices.Marshal.ReleaseComObject(oBooks);
                oBooks = null;
                oExcel.Quit();
                
System.Runtime.InteropServices.Marshal.ReleaseComObject(oExcel);
                oExcel = null;


Another problem I probably will have is to run the find function for all 
sheets.

thanks for advanced.

Marc

Auto-format in Microsoft Excel.
Each time i try to enter a number range, for example, 8- 10, in Excel, it constantly re-formats it to a date. If I change the formatting to "General" it turns it into a random number, usually 38209. I would like to turn off ALL auto-formatting, but that's probably asking too much. How do I disable this frustrating feature? thanks. Hi Paul When you enter "8-10" in a cell, that's not strictly a number but Excel thinks you mean a date so converts it as such. A date is a number and in your example the number 38209 represents August 10 2004 which is not a ra...

Unexpected error message on closing an Excel file
Suddenly I am getting the following message when I try to close a workbook: "Your formula contains an invalid external reference to a worksheet. Verify that the path, workbook, and range name or cell reference are correct, and try again" The mysterious thing is that it does not happen consistently and that, after I click OK after the above message, I can still save the file. What might be the cause of this error message and can the "invalid reference" be tracked down using one of the utility add-ins such as J. Walkenbach's PUP? If it only happens when you close ...

Excel DNS query
