QueryInterface for interface Excel._Application error
We are using Excel 11.0 library in one of my c# project. We instantiate the
excel objects in the c# code and creating excel file on the server side. The code is working fine on the local machine but it is failing on the dev machine with the following description. Both machines are having excel 2003 installed. The QueryInterface for interface Excel._Application failed. I am sending the the excel code to this mail which causes this problem. I am confused why this problem occurs. Please reply me in details. The code as follows: Excel.Application exlApplication = null; Excel.Workbooks exlWorkBooks = null; Excel._Workbook exlWorkBook = null; // Create the Excel application object exlApplication = new Application(); exlWorkBooks = exlApplication.Workbooks; exlWorkBook = exlWorkBooks.Open(strXMLPath,Type.Missing,Type.Mis sing,Type.Missing,Type.Missing,Type.Missing,Type.M issing,Type.Missing,Type.Missing,Type.Missing,Type .Missing,Type.Missing,Type.Missing,Type.Missing,Ty pe.Missing); exlWorkBook.SaveAs(strEXLPath,XlFileFormat.xlWorkb ookNormal,Type.Missing,Type.Missing,Type.Missing,T ype.Missing,XlSaveAsAccessMode.xlExclusive,Type.Mi ssing,Type.Missing,Type.Missing,Type.Missing,Type. Missing); exlWorkBook.Close(null,null,null); exlApplication.Workbooks.Close(); exlApplication.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComO bject (exlWorkBooks); System.Runtime.InteropServices.Marshal.ReleaseComO bject (exlWorkBook); System.Runtime.InteropServices.Marshal.ReleaseComO bject (exlApplication); exlWorkBook = null; exlApplication = null; exlWorkBooks = null; Waiting for your response.... Thanks & Regards Kowshik. |
