View 2 Replieshow I can use excel 2003 and excel 2007 on my application. I add a reference to Excel 12.0 Object but this one is not compatible with Excel 2007 and i think if i add Excel 11 Object it will not run on excel 2007.
Is there any solution that I can use so that my project can be used with either excel 2003 and 2007?

I have both Excel 2003 and Excel 2007 installed on my system. When I call oExcel = CreateObject("Excel.Application"), Excel 2003 is used in the context in my .NET code instead of Excel 2007 (which I need to be used). I have referenced the "Microsoft Excel 12.0 Object Library" but when the code runs, the 11.0 version is used.
Is it because I am using Visual Studio .Net 2003 that Excel 2007 cannot be correctly referenced or do I need to change a reference or setting?
The following code works fine in 2003 but generates an error in 2007:
Worksheets("Sheet1").Shapes("txtTest").TextFrame.Characters.Insert ("ABCDE")
Worksheets("Sheet1").Shapes("txtTest").TextFrame.Characters(6).Insert (",FGHIJK")

Assume all traces of Office 2003 will be removed from the computer.I understand that I will still be able to use .xls files. I'm asking about automating Excel through the COM interop from outside Excel. When I add a reference to Excel to a VB project, it gives me a different version of the dll for different versions of Excel. If a program was compiled with a reference to Office 2003's dll, will it need to be recompiled for Office 2007? Will the code need to be updated to use the new dll?
View 2 RepliesI 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.

how can I let VB.Net writes an excel 2007 file? For example, the data in a TextBox will be written to the excel file every 30 seconds.The enviroment is VS2008, .Net 3.5.I've just started VB for one month, so please give me a piece of code to help me understand. I tried to find the solution on the Internet, but none of the codes worked for me, some people mentioned import "Microsoft.Office.Interop" in the code, but if do that in my code, VS said that "Namespace or type in the Imports 'Microsoft.Office.Interop' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."

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 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:
NPOI
MyXLS
ExcelWriter (softartisans)
JetCell (DevTrio)
Aspose.Cells (Aspose)
But I do not know which one is better for my needs. I need to export not only grid row data but also Chart (image), thats why I am thinking about.
I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008.

I work for a somewhat large company.There are about 160 Windows XP Pro users. We are still using Microsoft Office 2000 for the most part.We have upgraded some users to Office 2003. We are not using Microsoft Exchange.I have to export every users' Outlook 2000 or Outlook 2003 Contacts into an Excel or CSV file every 6 months as a way of backing the Outlook Address Contacts.Currently I am doing this by physically going to every pc and manually exporting the contacts.This is a large pain.I am trying to find out if I can use or create a Visual Basic 2008 Express program or script that will export the contacts from Outlook and save it as an Excel or CSV file.The name of the file should be the same as the computers net name.It should be saved in the same location, on the network, each time.I am new to programming and new to VB 2008 Express.I do not know or have any code to start with.
