I have a query being created using oledb from access and need to get the information to an already existing excel spread sheet. I am using VS 2010 with vb.net, access and excel are 2010. I have been running in circles for the last two days and cannot figure out how to get the data from a datareader into excel. This is a vb.net console app, so no web tables or grids can be used.

I wont to export query results from Access to Excel.From my Access app i execute this function
Public Sub qExcel(pQuery As String)
DoCmd.Hourglass True
Dim dbs As ADODB.Connection[code]......
Everything is OK when I run this function for the first time. But when I try to run it the second time I get method range of object _global failed error.Also I've noticed that first execution creates excel process that is in my process list even after I close excel. Second execution creates second process and after error when I close excel both processes are gone.Third execution creates no error fourth creates errors .... and so on
I have this working on VB6 that saves a query in a excel sheet:

The XLSNombre is a variable with the name of the excel file that has been set before. The connection I have in .NET is to SQL server (but is the same). How can I use this code (or..how can I make this code work for .NET) or what is the equivalent of this for .NET? I found some solutions but with inserts of single rows or I have to set the title of the columns, I dont find any "simple" solution to do an "insert into" (like the code I use in VB6).
I'm running into a bit of a roadblock here. I have tried to search the web/forums for answer for last several hours to no avail and I'm not the expert VB Programmer.However, I was able to write an app to do the following:
1) read Outlook emails for particular emails containing xml link in which I was able to download the file and save to my hard drive.
2) opened the Excel spreadsheet to run the macro which import those XMLs into existing XLS spreadsheets to refresh the data.
3) Those XLS spreadsheets are linked in my MS Access in which I join all four XLS sheets to create one report via Query which I have created in the past prior to this app development.
I have manually done a File Export of this query via ALT+F then E and what I'd like to do is to either take control of menu commands OR alternate method of performing a File Export to a new Excel spreadsheet (version 2003).I've seen two different methods, one via DoCmd OutputtoFile and another is TransferSpreadsheet.Here's my Access coding I have in my VB 2010:
Imports Microsoft.Office.Interop
Public Class OutlookOfflineEmailExtractor
Dim wsAccessApp As Access.Application

I 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 RepliesI have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls

"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid.

I need to export Chart(image) and grid (tabular) row data into excel file. I can not use automation because Office tools are not installed in my server. I've found a bunch of free/proprietary tools like:

JetCell (DevTrio)
Aspose.Cells (Aspose)

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

I have done a google and see that many people have asked the question on how to export a Datagridview to a Excel (.xls) file. For some reason I cannot seem to get it to work (i have gotton the program to open an Excel and save it, all hidden in the background). I use a bit of the coding from this source code [URL] but modified it and incorporated it into my program. It connects an OLE Database connection with the excel sheet... but what i want to do is beable to alter the sheet in the datagridview and export it back to an excel sheet. I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..
