How To Export To Excel From WinForm Without Office Installed
Sep 9, 2009
I 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):
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."
And for the record, I need the excel file, not a CSV.

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:
I have a function in my application which exports data to excel. It works fine when it is installed in a pc where office is installed. How can I run in a pc where Office is not installed? Do I need to install full Office in user computer? Are there any redistributables which makes my work done??
[URL] using this method results in a modal dialogue box which the user must manually close by pressing end or debug or the VBA (and consequently the VB) code will hang.I am unsure how to get the message box to close.
I am writing a WinForm app on Visual Studio .Net 2005 which will be a rudimentary "unit tester" for various MS Excel 2003 applications...basically, it will ensure the integrity of the VBA code which fires off in the event lifecycle of the workbook.As a test for a "unit test failure," I created a simple workbook which generates a runtime error at the Workbook_Open event in the VBA code (an intentionally placed out-of-index call to an array). I have no problem opening workbooks via the .Net WinForm using the Excel Object library. My problem is that the run-time error is not captured by the WinForm app -- instead, it throws the runtime error directly on the Excel thread which the WinForm app starts.Is there a way for the WinForm app leveraging office interop to catch that excel runtime exception?
I've tried encasing the call in a Try-Catch block using a general Exception a COMException (via the System.Runtime.InteropServices library) catch...I've also tried instantiating the workbook directly using CreateObject(sPath) and instantiating an Excel Application, then using that to open the workbook...all with the same results...instead of the .Net app catching the exception, the runtime error bubbles up directly to the Excel application.Is there any way, either on .Net or the VBA code, for the WinForm app to catch and handle an Excel run-time error?
I have a software that writes data to Excel sheet. I'm using Microsoft Excel 11.0 Object Library for this. Everything is working fine so far, but apparently the drivers require Microsoft Office installed onto the computer.
Is there a way to write data to Excel format without having Microsoft Office installed?
I am working with Vb.net and this code below works fine. However, when I review the data exported to excel I have a problem with one particular field i.e., sort code,( Columns (2) ) Sort code in the database it is in the format 00-00-00. Therefore if it is 12-11-09 or 11-01-66, a look alike of a valid date it is displayed as 12/11/2009 and 11/01/1966 in excel after the export. Excel thinks its a date which is incorrect. I expect it to show 12-11-09 and 11-01-66.

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 have created a Customized Excel template for Office 2007 using VSTO. currently i am showing this template under my templates. is it possible to show under Installed templates?
like we have in office 2007 Billing Statement, Blood Presser Tracker, Time Card , etc. Is it possibe to show the template which is created by me; under Installed templates?
So I'm guessing it has something to do with the fact that I don't have office loaded on my computer. Now I have another laptop, with office that I loaded this project on, and it works fine. So do I have to load office on this computer, or can I just reference something?
Background: I have a winform application written in VB.NET that uses a WebService to send out different invitations to users based on the marketing company they select to take different interviews. The winform app is pulling string values from a variety of textboxes, listboxes, and dropdownlists to create some XML and push it to a web service called AcompServiceClientQuestions:

i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type
I'm working on a VB2008 project that references two Access databases using Provider=Microsoft.Jet.OLEDB.4.0; It would seem if the user does not have MSOffice on their machine, the program crashes with a "XXX stopped working" on startup on Vista and Win7.I thought that Windows had XP and above had Jet functionality built in?
I am working on a legacy VB.NET application that uses Microsoft.Office.Interop.Word, with Office 2003 installed on the server. When I publish my site, even though my config file clearly shows v11: The site will crash saying v12 couldn't be found: Could not load file or assembly 'Microsoft.Office.Interop.Word, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Note: I currently have Office 2003 & 2007 installed on my dev machine, also, when looking @ references I am given the option of selecting v11 or v12 (so v11 is def. there). Within a page on the site the page does an import statement for Microsoft.Office.Interop.Word. Is it possible to specify the version at this point, or any way to force it to use v11 without me uninstalling my v12?
I have office 2007 installed on my development PC but would like to include Office 2003 Object library in the project as a COM reference. Can I download the required files from anywhere for this or do I have to install Office 2003? |+--JDMils|+--VB6 & XL VBA+--VB Dot Net 2K8|
I installed the API redist [URL] for Office 2010 (Office 2010 was already installed). Then I tried to use code from MSDN [URL] just to see how it worked. I included the code here, since it's short. At the top of the file:
Code: Imports Outlook = Microsoft.Office.Interop.Outlook
... and in the class:
Code: Private Sub SendSalesReport() Dim mail As Outlook.MailItem = CType(Application.CreateItem( _ Outlook.OlItemType.olMailItem), Outlook.MailItem)
[code]....
Unfortunately, VS2010 balks at the very first line, not recognizing the namespace. What do I need to do?Oh, and I can't find Microsoft.Office.Interop.Outlook.dll anywhere, either. Shouldn't that have been installed?
I have a WinForm program developed in VB.Net with Visual Studio 2005. The program needs Microsoft Office Runtime installed atleast on the computer to allow the application to run without any errors.
Is their a way to check the computer to see if the minimum of the Runtime or Microsoft Office is installed on the computer? If either isn't I would like to display a message to the user on the startup of the application that states to atleast go to Microsot's site (I have full link to Runtime Download) and download the runtime for free.
Or is their a way to include the runtime as a component with my install for the application so if it isn't installed on the computer already it will install when the application is installed?
I 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.
I have a project that has a need to display a Excel file in second window, but because other controls are needed, simply launching excel is not sufficient. Right now I do not know if the target machines have excel installed but I know with certainty that if they do it would be 2010, is there any method or library that allows you frame your own form around an excel window?
I am uploading an excel file to my app and want to read it. Do I need to have excel loaded to read this?I am getting an error of Object reference not set to an instance of an object.

I tried to read excel file using the method i found here [URL] But i get an error on ADODB.Connection saying "Type 'ADODB.Connection' is not defined" in the following code:

Question: How do I programmatically determine which provider to use (Microsoft.Jet.OLEDB.4.0 vs Microsoft.ACE.OLEDB.12.0) when my app runs as a 32-bit process on a machine with Office x64 installed?
I'm developing a VB.net WinForms app in VS 2010 and targeting both x86 and x64.The app processes data from xls, xlsx, mdb and accdb files using System.Data.OleDb:Dim oConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...")
The x64 version of the program works as expected. The x86 version works as expected on a system with Office x86.When I run the x86 version on a machine with Office 2010 x64, I get the following exception when trying to open a connection:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.I believe this is because I'm running Office 2010 x64 so the x86 data access components are not installed.I can get it to work for Office 2003 files (*.mdb and *.xls) by changing the provider to Microsoft.Jet.OLEDB.4.0.
How do I figure out which provider to use when running as a 32-bit process on a machine with Office x64 installed?Ideally, I'd like a function:If ProviderIsAvailableFor("Microsoft.ACE.OLEDB.12.0") Then
Else If ProviderIsAvailableFor("Microsoft.JET.OLEDB.4.0") Then
I am exporting data from vb.net to excel and it is dropping the leading zero when its displayed on excel. How can I avoid the dropping of leading zero? I read the solution of adding a single quote but it makes my excel sheet column ugly. Also users will complain if they see a single quote on zip code field.vb.net code
adding a single quote or manipulating excel sheet with column formatter (general/numbers ) etc. I don't want user to make any changes on excel to get the display properly when the excel is displayed from web page it should be all set with proper formatting. also we have no control over client excel software?
I'm trying to export a datagridview to Excel and open the Excel spreadsheet (not SAVE the worksheet).
Public Sub ExcelRpt(ByVal DgvName As GridView, ByVal url As String) Dim xlApp As Microsoft.Office.Interop.Excel.Application Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.
