I just installed Microsoft Office 2010 (I'm guessing this has some references the program needs), and I'm using Visual Studio Community 2017, what reference do I need to add to write and read .xslx files?
Edit:
The Microsoft Excel 14.0 reference just appeared on the COM list, but I still can't make a file. I'm guessing I need to import something now?
This assumes you actually got the reference added as you state.
So then add this at the top of the code window
Imports Microsoft.Office.Interop
and this in your code:
Dim objApp As New Excel.Application
objApp.Visible = True

I'm using vb.net (Visual Studio 15) and have MS Office 16, and when I added the COM reference Microsoft Excel 16.0 Object Library to my project, it didn't take. I actually had to browse (in the add reference window) to the following location an add a dll:
C:\Windows\assembly\GAC_MSIL\microsoft.office.interop.excel\15.0.0.0_71be9bcellle9429c\microsoft.office.interop.excel.dll

Ultimately I want to build a MS Project file using early binding from VBA behind XLS or MPP.
In order to do that, it is my understanding that you should go to Tools--> References and select the Microsoft Project XX.X Object Library.
Unfortunately, it wasn't in the list.
The References pop-up allows you to browse, and select the reference library manually. Great! But, where do I look, and what file do I select to import this reference?
Assuming you are looking in Excel VBA References's list, it should just show up. Here's mine:
Note that I see it as Microsoft Office Project XX.X Object Library, you asked about Microsoft Project XX.X Object Library (lacking Office).
My environment is Win10; both Excel 2016 32-bit and Project 2016 32-bit are installed.
Perhaps try re-installing your Office components? Perhaps try making sure you have both the same bit architecture (32 or 64).
I have a problem with running a VBA in a Excel spreadsheet on a MacOS (Sierra). On Windows everything works like expected. I always get the "Compile error in hidden module: Interpolation ...
I tried to remove the whole content of the module and this is the leftover:
Function interpolate(x As Double, ran As Range) As String
interpolate1 = 1
interpolate = interpolate1
End Function
The VBA code is password protected and I don't use any ActiveX controls.
The references I use are as follows:
Visual Basic For Applications
Microsoft Excel 16.0 Object Library
OLE Automation
Microsoft Office 16.0 Object Library
Microsoft Forms 2.0 Object Library
RefEdit Control
If anyone has any suggestions on how to go about this problem, that would be great.
Thanks,

The RefEdit reference was missing on MacOS. I removed it and now it seems to work.
I've written a piece of kit on Excel 2016 that uses a combination of formula and vba macros.
Basically some of the people that will be using this may be using an older version of Excel (2013 or 2010). When testing out whether the file will run on 2013 the Microsoft Powerpoint 16.0 library was missing and some of the code would not run.
The only fix was to add the Microsoft PowerPoint 15.0 library and then it seemed to work.
Is there any way to add the libraries automatically when I send this file to other people, or add the 15.0, 14.0 and 13.0 library's in my copy so that this is not an issue for other users?
[EDIT] From further reading it appears that older versions of excel use different libraries and it doesn't look like you can "pick and choose" whether to use 16.0, 15.0 etc. (Please correct me if I'm wrong). Apparently there is something called "Early/Late Binding" which might help me out, I assume this is referencing within my actual VBA code so if that is a viable solution any more information would be appreciated.
You have two options.
Develop on the lowest common denominating Office version (references will automatically "upgrade" on newer versions)
Change your code from early binding (using a reference to the library) to late binding (using generic Object declarations for everything related to PPT, replacing all PPT constants with their associated values). You then get a reference to Powerpoint using the CreatObject or GetObject function.
I am using Visual studio 2012 with MySql database .. I am trying to generate simple report using Forms. When click on button the reports will generate in EXCEL sheet. The problem that I am facing is using this library: using Excel = Microsoft.Office.Interop.Excel; when I used it says : One or more types required to compile a dynamic expression cannot be found. Are you missing a reference?
as shown in the figure !!
Please Any Help ??
Thanks in Advance
I have sort out the problem :)
A default project in Visual Studio 2010 should have references to Microsoft.CSharp and System.Core.
In 2012, If they are not referenced in your project you need to add them, and the errors will go away.
Thanks
I am trying to import xml data into excel..
So the first line of the code is
Dim XMLDOC As MSXML2.DOMDocument
and this gives an error "user defined type not defined"
Inside the VBE, Go to Tools -> References, then Select Microsoft XML, v6.0 (or whatever your latest is. This will give you access to the XML Object Library.
Updated with fancy pic!
I had DOMDocument defined which needed Microsoft XML, v3.0 but I had Microsoft XML, v6.0 selected in references which caused the below error
"user defined type not defined".
The solution
The solution was to either change DOMDocument to DOMDocument60 (60 uses ver 6.0) or use the Microsoft XML, v3.0 reference with DomDocument.
Just a quick note, if anyone is using a different version, such as Microsoft XML, v4.0, then DOMDocument40 should be used. This is because the number at the end of the DOMDocument is specific to the version of the library being used.
I work with a VBA Excel Macro that someone else wrote and I was tasked with fixing it after recently upgrading from Windows 7 / Office 2010 to Windows 10 / Office 2016. I started to receive the same "user defined type not defined" compile error. My previous install also had MS XML v6.0 but apparently you have to specifically point to this version in your code on Windows 10 and/or Office 2016 (I wasn't able to confirm which upgrade caused the issue). I was able to resolve the issue by doing a Find/Replace on the following:
"DOMDocument" to "MSXML2.DOMDocument60"
"XMLHTTP" to "MSXML2.XMLHTTP60"
I am using Microsoft Windows 10 & Office 2016.
Using Microsoft XML 6.0 does not fix the problem.
Selecting Microsoft XML 3.0 fixed the compilation error
I had the 3rd and 6th versions installed, and the project uses the 4th one. I installed the 4th version from https://www.microsoft.com/en-us/download/details.aspx?id=15697 and this solved the problem.
