Cannot Create ActiveX Component - EXCEL - Does Server Have To Have Excel Installed
Apr 1, 2009I have read some of the other posts on this and seem to be a little different than my situation. Trying to print out some reports into an excel document on the clients machine - of course it works fine on my local (heard that before right). I went in and set my references Ms.Office.Core and Ms.Office.Interop.Excel to 'Copy Local' = True so the .dll are in the servers bin folder.

Asp.net Using Oledb To Export Excel File Returns Empty Excel File
Feb 24, 2010I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

View 1 RepliesOpen Excel File And Reusing Existing Excel Instance?
Jul 13, 2010I have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.

How To Export To Excel From WinForm Without Office Installed
Sep 9, 2009I am building a windows form application using visual basic (visual studio 2008). The idea is to query a MySQL DB and export the results to an excel document. I managed to do this using this code (I will just show the export to excel part):
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.IO
Imports System.Data
Imports MySql.Data.MySqlClient
Imports System.Configuration
Imports System.Runtime.InteropServices

And it works fine on my laptop (which has office 2003 installed), but when I create the setup package and install it on the server where I am going to use it (which does not have office installed), I get this error:
"Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154."
