I am trying to get an Excel reference working and it will not go. I had the working on an xp computer but I got a new laptop with Vista Premium (64 bit), and it is not working here; and I got it from the references and com. In the intelliSense I get only up to "Imports Excel = Microsoft"

I am using vb.net 2005 and my laptop has a reference to excel 8.0. I have created a progam that uses excel 8.0's reference. While excel works fine on my laptop, it does not work on my pc because I have excel 2007 installed. My question is, is there a way to obtain the reference to excel 2007 for my laptop in order to use it in the .net project. I do not want to upgrade my laptop right now and my pc does not have vb.net installed on it.

View 1 RepliesI'm trying to upgrade a VB6 app to VB 2008. I have read the article in the tutors corner about automating Excel from VB but I cannot get it to work. Heres what I have done:
1) set a reference to the Microsoft Excel 12.0 Object Library
2) Added "Imports Excel = Microsoft.Office.Interop.Excel" to the top of the module
3) in a routine I have added: Dim X As New Excel.Application Here's where I get an error: Error 75 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.
I deploy a project under vb.net 2008 express successfully. My code nneds a reference of Excel. But when I run it under Visual Studio 2005 Profession Edition, I am unable to find Microsoft Excel 11.0 Object Library(or any lower version).
View 6 RepliesI have a dataset that I export to xml (using ds.WriteXml) and then use an instance of Microsoft.Office.Interop.Excel.Application to open and manipulate the xml data, then save it as an .XLS file.I have office 2007 (why don't they have help/about in an easy to find place... man I hate those stupid office ribbons and the person who developed them...)Anyway, this code works fine for me. But when I put this on a machine that has office 2003 installed, it crashes.So, what do I need to install, reference, buy, etc. so that I can do the same thing on machines that have 2003 (or before) installed? No, I can't install office 2003 (my first thought).
View 8 RepliesI'm using comboboxes in my user form in Excel. I have two boxes, FromCombo and ToCombo, the first of which I have assigned values to using [Code] Now, my problem is getting the second combobox to work. I want it to drop down a range of values depending on what the user picks for the FromCombo. I have named the ranges List1, List2. Say the user chooses "KA 1&7" from the FromCombo, how do I populate the ToCombo with List 1? I thought it would be easy to use if statements and compare the value in the FromCombo so I use this Code: If FromCombo.Value = "KA 1&7" Then but its not comparing. So how do I compare the value in the FromCombo box?

View 2 RepliesI need to read data from an Excel workbook in my VB2005 application. I've add a reference to the Microsoft Excel 11.0 object (as I'm using Excel 2003). However, I got the following error when I build the project:

So I've been trying to write an Add-In for Excel for a week now. I already have the add-in made up in VBA (CustomUI.xml has been added too for a ribbon). I've been using it for awhile now from Excel's VBA Editor. But I want to get a bit more fancy with it, so I'm going to re-write it in VB.net since it's ribbon designer is nicer than writing XML code by hand. The only problem is, I've been very confused on how Visual Studio sets up all the references to Excel.As I've been looking through examples in threads across this forum I see a lot of people using this code to get access to Excel.

View 3 RepliesI have created a C# .Net DLL add-in for Excel.When I try it on my home machine with WinXP and OfficeXP 2003 it works as expected. When I try it on a couple of machines at work with WinXP and OfficeXP2002 it does not work.I have spent 2 days solid reading up on this subject in general and I still cannot get to the bottom of the problem. As far as I can work out what I am trying to do should work with Excel 2002.
Some details:
- I am using Visual Studio EXPRESS 2008 (C#).
- The assembly is signed with a Strong Name Key File.
- I have installed the OfficeXP (2002) PIAs.
- I have created a class DLL in accordance with many MSDN and other internet posts.
- I have registered the DLL using RegAsm.exe and GACUtil.exe.
- I have added registry entries for Excel for CURRENT_USER so Excel should know about the DLL.
The DLL adds some Automation functions (Tools-Addins-Automation) which can be accessed in cells within Excel (for example you would enter =MultiplyFirstBySecond(2, 3) in a cell and get a result of 6) and also implements the IDTExtensibility2 methods so that when Excel is opened it creates a button on the toolbar which when pressed pops up a message box. It it this functionality (adding buttons with code behind them) that I want to expand on.I have attached the zips of the batch and registry files I have created to register the DLL in the GAC and in the registry. I have also attached a zip of the complete project. I would like to know if there is anything I should check with my machine's setup or my project or my registration/installation of DLLs, PIAs etc in order to make my DLL work on my Excel 2002 machine.
Excel returns a reference of the form
=Sheet1!R14C1R22C71junk
("junk" won't normally be there, but I want to be sure that there's no extraneous text.)I would like to 'split' this into a VB array, where
a(0)="Sheet1"
a(1)="14"
a(2)="1"

I'm sure it can be done easily with a regular expression, but I just can't get the hang of it.
I'm a VBA programmer and can do Office integration in Office applications.I'm programming in VB in VSTS 2008 and following these steps to create an Excell application at runtime: [URL] but it is not working.The issue I'm having is when I add the reference, the library is not recognized by VBE intellisense and compiler, so: the code doesn't run.When I use late binding technique and declare variables as objects, the code runs OK, but I don't want that way.I tried adding the references in two different ways:
1 - Menu Project / Add Reference / tab COM / Microsoft Excel 11.0 Object Library / OK
2 - Menu Project / VB Properties / References / Add / Microsoft Excel 11.0 Object Library
Both methods didn't work.

I have an application that I originally wrote in MS Basic. It has since migrated to VB6 and then to VB Net. It works, but recently I have been unable to rebuild the project and an attempt to convert from VB6 has produced an error on converting and MSMaskEdBox as an array.

If I leave a blank after New, VB Net presents me with a drop-down list, which includes I have recently tried to convert the project on my laptop and the above line of code produces an error. When I try to add a property(?) after New, Excel is not in the list of those available.
