I'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 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 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:
"Warning 1: Namespace or type specified in the Imports 'Excel' 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. (follow by the path of 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.

at the top of every sub routine that I'm going to be using excel in? Isn't that going to open a bunch of different windows and separate my code from the data I'm trying to manipulate?
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.

View 7 RepliesI can reference the local (generic) data directory for an SQL file as follows:
Dim
T01Database As SqlCeConnection =
New SqlCeConnection("Data
Source=|DataDirectory|Test File.sdf")
I get a "file not found" error when trying the same syntax for referencing an Excel file:
Dim
T01Workbook As Microsoft.Office.Interop.Excel.Workbook

correct syntax for referencing an Excel file in this manner?

I am rather familiar with the ins and outs of VB.NET and Database Selects, Updates and Inserts. Not so good with Transactions. (Oracle, MSSQL)
for example, take a Billing System for a hardware store.I create a 'New Order' and select the Cash Customer I start adding items to this order. 1 Rake 1 Shovel Where do I store this information (temporarily) until the user hits 'SAVE'. Maybe the customer decides they don't want the items. Too expensive. I just EXIT. nothign to do.
Or - I open an existing order and make a bunch of changes. Where do I put these changes until the user hits SAVE. I am sure transactions might have something to do with this - or temporary somethings??? I just don't know and need some guidance.
I have Visual Studio 2010 and a VB Project that had a reference to Microsoft.Interop.Excel 12.0. Well recently I changed the reference version to 14.0. That was actually a mistake and now I need to bump it back down to version 12.0. However I get this error in my project now...
Project 'MyProject' requires a reference to version '14.0.0.0' of assembly 'Microsoft.Office.Interop.Excel', but references version '12.0.0.0'
of assembly 'Microsoft.Office.Interop.Excel'.
I tried removing references and adding the com object to, but no avail.
I'm building SQL statements with a bunch of values from a dataset. Obviously that gives some really long names to put inline or even in parameter. addwithvalue code so beforehand I just declare a bunch of variables with really short names and assign them to the DS's exact fields like: [code] but this way I'm putting all the data in the dataset into memory twice by copying it into a new variable, right? So I was thinking, if it's just a string variable representing a field on the dataset, why not declare it by reference so the variable is basically a handy nickname pointing to that field in the dataset.Will it even work to have a string declared by reference and connected to one value inside of a dataset? And if so, will that stop duplicating everything in memory? I forgot how to declare a variable as a reference to another variable instead of the normal way in VB.
View 12 RepliesI have a windows form application and also a exe application that both uses the same dll whic I place in the bin directory The dll is using crystal report and thus I need to reference com objects and other .net drivers. My question is following: Where should I put these references, in the class library (dll) or in the windows form / exe applications. If I put them in the dll, will they automatically be loaded when call the dll (entry point) or do I need to something else (create in installer etc)
