VS 2008 : Adding Excel Library Reference Is Not Working?
Sep 20, 2009
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'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 have a class library called Encrypt.dll that I added to my project (that class encrypts strings..). I have a problem that when I drag the app out of the Release folder, it crashes, giving me this error:Could not load file or assembly 'Encryption_Class, Version=1.0.0.0...' or one of its dependencies. The system cannot find the file specified.What am I doing wrong?I added it from the Reference tab->Add->Encrypt.dll

I've added a COM reference to one of my projects (the DLL resides in C:Program FilesIntwerwovenWorksiteiManage.dll) but when I view the References in my project the path is something like c:usersusernamedocumentsvisual studio 2008project nameobjdebugiManage.dll..I seem unable to edit this path. I can remove the reference and re-add it using the browse button, picking up the correct dll but it keeps showing as the path of the project.The application works on my development machine but as soon as it's deployed to a client machine it complains of the missing DLL. Of course, the DLL is present but the app is looking in the debug folder.

I am using VS .net 2003 and developing a program that calls Excel. The development computer only has Excel 2003, and the target machine only has Excel 2007. Would it be possible to install Excel 12 Object Library in the development computer without installing Excel 2007?

I have been doing a lot of reading on this topic and most folks seem to agree that having Excel is required to use the COM Interop libraries. However they are never specific as to where that should be installed. Does it need to be installed on the machine I am developing on or does it need to be on every machine that I deploy to?
Edit: I should mention that this is desktop development/deployment targeted for all Windows machines.

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?

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.
[Code]...
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?

If printed = False Then

I was looking at tutorial that was detailing how to Build a Class Library Component and Consumer Client Application. One of the steps involved was how to add a reference to a library. Am I right in assuming that the reason for adding a reference is to show Vb where class library is located. I would also like to know if it is possible to add the reference within the code. In the tutorial the reference was added via the top menu (selecting project and add reference).

The problem I have is that I have a 3rd party add-in working in excel to convert certain info into a barcode.
When I open excel normally, the add in works without a problem, but when I open it through excel it just doesnt work until I manually go into the add-in option, disable the add-in and the reenable it.

This is strange. I tried to create a new project to reference the Outlook Object Library, but I can't get the code references to work. Here's what I'm doing:
Quote:# Start Microsoft Visual Studio .NET.# On the File menu, point to New, and then click Project.# Click Visual Basic Projects under Project Types, and then click Console Application under Templates. By default, Module1.vb is created.# Add a reference to the Microsoft Outlook 12.0 Object Library. To do this, follow these steps:
1. On the Project menu, click Add Reference. 2. Click the COM tab. 3. Click Microsoft Outlook 12.0 Object Library, and then click Select 4. Click OK. If you are prompted to generate wrappers for the library that you selected, click Yes.
# In the Code window, replace the default code with the following code:

Okay normally this was easy to do, but now with IE9 Visual Studio 2010 hangs and crashes. The problem seems to be even worse because you can't build an Interop.mshtml.dll to match version 9. I've tried using the VS command prompt with no luck. Allegedly this is how it is done, but there are no known examples that actually work. If anyone has done this with success

I've created a class library and it's shared by several projects I'm working on.
I added a reference to the DLL - but it appears to have copied it locally - and that's causing problems when I modify the class library. Seems I have to drop the reference and re-add it.
I'm seeing info on the web about adding a PROJECT REFERENCE but can't seem to get that to work.
What is the best method of sharing a class library with several other projects.
Actually - should all my projects be in one SOLUTION? Is that preferred.
It will be 5 projects all working with the same class library...

I am trying to add some style properties to a column but the code I am currently using doesnt seem to work at all?
Dim oApp As New Excel.Application
Dim oWB As Excel.Workbook = oApp.Workbooks.Add()
Dim oWS As Excel.Worksheet = CType(oWB.Worksheets(1), Excel.Worksheet)
Dim style As Microsoft.Office.Interop.Excel.Style
style = oWB.Styles.Add("Style1")
[Code] .....
It's still the same as "default" would look when just opening up excel for the first time.

My module won't run, it can't find the project or library, and highlights: the Date function in: MsgBox (Date).This is happening to several VBA functions, but this is the first one.I have all the libraries referenced that I think I need, especially the Visual Basic for Applications checked.There is a MISSING: Office12 library, but the Date function is part of the VBA library, so I don't think this should be the issue.

I have a solution built of 3 projects:
1. VB.NET Class Library - data access and objects, reusable methods, etc.
2. ASP.NET Web app - web application that references the class library
3. VB.NET Windows Form app - windows app that references the class library
I have no problems with the web app. It referenes the class library and every time the project is built the web app gets a freshly compiled dll from the class library.
My problem is with the windows form app. When I first add the reference to the class library project, I get all of the intellisense I'd expect while coding. When I try to compile, though, it's like the reference disappears and all my code that is based on the class library errors out with "'xxx' is not declared" or "'xxx' is not defined" where 'xxx' is a method or class within the class library. If I go into the project properties, the reference is still there, but the project no longer compiles and I also lose intellisense for all classes within the class library. If I remove and re-add the reference, it works again, until I try to compile. Then the errors occur again.
I've tried creating a separate Windows Forms project and just referencing the DLL created by the class library but get the same problem. HOWEVER, if I create a seperate blank WEB project and reference the dll (or the project), everything compiles fine. It seems to be something with my class library being referenced by a windows forms app.
For reference purposes, my class library has the following references:system, system.cor, system.data, system.data.datasetextensions, system.drawing, system.web, system.xml, system.xml.linq I noticed I can't add a reference to System.Web in my windows forms app, and I wonder if my problem is somewhere in this area. I need the reference is my class library because it passes some HttpContext objects back and forth to a few of the methods.
