I have not done any programming for quite some time, so apologies if this is simple. I have had a look on several forums but haven't found quite what I am looking for.
I have Microsoft Office 365 ProPlus with Excel Version 1902. The Office version was pushed centrally form IT; a click to run type deployment so I didn't have options to ensure PIAs were enabled.
I am using C# in Visual Studio Community 2017.
I am wanting to include the Microsoft.Office.Interop.Excel reference to allow me to do certain operations in Excel from within my application.
When I attempt to Add the reference to my project, under assemblies there are non of the PIAs available.
However when I look under the COM options there is the "Microsoft Excel 16.0 Object Library" available.
How do I install or enable the PIAs so that I can use these with Office 365?
I am needing to create an Excel spreadsheet from a c# project, but I cannot add the reference to the Excel COM object.
I am using Visual Studio 2010 and office 2013. I've clicked on the References folder and selected Add Reference, and then navigated to the COM tab, setting them in alphabetical order. I looked through, but there was no reference to Microsoft.Office.Interop.Excel.
Trying to resolve the issue, I downloaded and installed the PIAs for Office 2010, but references still were not added. I'm not sure where these files would be located on the hard-drive, so I cannot just browse to them (or copy one to the project Resource folder and reference it there).
Does anyone have an idea as to why I cannot see the references?
Additional Information
I managed to get the Microsoft.Office.Interop.dll file from a coworker for Office 2013, but I was not able to reference it from my project since I am working in .NET 3.5. My manager does not want me to update the project to .NET 4.0, so it looks like I will need to use the Office 2010 PIAs I installed. Unfortunately, installing them did not add them to the list, and I haven't been able to find the dll's to add them by browsing to them.
I doubt that it will make a difference, but my dev system is Windows 8.
I am trying to integrate Microsoft Word with C#. But when i am trying to add Assembly "Microsoft.Office.Interop.Word" I couldn't find this in the reference list:
What am I missing? I'm using Visual Studio Ultimate 2012.
Please help...
To add a reference to a primary interop assembly:
Open your Visual Studio Tools for Office project and select the project name in Solution Explorer.
On the Project menu, click Add Reference.
On the .NET tab, select the primary interop assembly you want in the Component Name list. For more information about the available Microsoft Office primary interop assemblies, see Office primary interop assemblies.
Click OK.
The assembly name appears in the References folder of Solution Explorer.
You need to install MS office to your computer.
Or download the Primary Interop Assemblies from here.
http://www.microsoft.com/en-us/download/details.aspx?id=3508
Then add it to your project reference.
I'm running Visual Studio 2010 Express, and in C# I'm trying to display Excel workbook.
I'm trying to use
Microsoft.Office.Interop.Excel
I have office 2007. Why doesn't this show up when I go to add> reference and navigate to the .NET or COM tabs?
Why doesn't this show up?
How can I add this as a reference or is there a better to show a workbook to the user in Excel?
For whatever reason VS 2010 doesn't like to show it in the .NET tab of the Add Reference window, you have to manually browse for it. The path to the assembly is C:\Windows\assembly\Microsoft.Office.Interop.Excel.
Go to Add Reference
Click on the Browse tab
Browse to C:\windows\assembly
Choose Microsoft.Office.Interop.Excel
I've had decent luck using EPPlus. It was awhile ago but I chose it since at the time the interop library was specific to a single version of Office whereas epplus was compatible with any version supporting the Open Office Xml format
Using the example provided in codeproject I am struggling to work out where I can find the reference to the library Microsoft.Office.Core.
I am getting the error "The referenced component 'Microsoft.Office.Core' could not be found."
I only have office 2007 enterprise edition and outlook 2003 installed on this system. Could this be the cause of this? Otherwise which specific dll am I supposed to be referencing?
You can add reference of Microsoft.Office.Core from COM components tab in the add reference window by adding reference of Microsoft Office 12.0 Object Library. The screen shot will shows what component you need.
None of the above answer helped me, i was using Visual Studio 2017. What I did is, installed Office/SharePoint Development using Visual Studio Installer.
After that, I was able to see 'office', this assembly contains Microsoft.Office.Core.
Hope this helps you.
You need to download and install the PIA (primary interop assemblies) for the version of Office you are using. Once installed you can then add a reference to your project and they will be available from the add reference dialog. Here are the links to download them...
Office 2010 PIA
Office 2007 PIA
Office 2003 PIA
After installing the Office PIA (primary interop assemblies), add a reference to your project -> its on the .NET tab - component name "Office"
If someone not have reference in .NET . COM (tab) or not have office installed on machine where visual was installed can do :
Download and install: Microsoft Office Developer Tools
Add references from:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Visual Studio Tools for Office\PIA\Office15
Now there is a nuget package for that.
https://www.nuget.org/packages/NetOffice.Core.Net40/
First I didn't find office in COM, so tried this nuget and it worked!
You can use this NuGet package which includes the interop assemblies in addition to the office assembly.
https://www.nuget.org/packages/Bundle.Microsoft.Office.Interop/
Have you actually gone to your references and added a .NET reference to the 'Microsoft.Office.Core' library? If you downloaded the example application, the answer would be yes. If that is the case, follow the advice in the article:
If your system does not have Microsoft Office Outlook 2003 you may have to change the References used by the "OutlookConnector" project. That is to say, if you received a build error described as "The type of namespace name 'Outlook' could not be found", you probably don't have Office 2003. Simply expand the project references, remove the afflicted items, and add the COM Library appropriate for your system. If someone has a dynamic way to handle this, I'd be curious to see you've done.
That should solve your problem. If not, let us know.
In case you are using Visual Studio 2012, for this to work and in order to make reference to Microsoft Office Core, you have to make the reference through Visual Studio by clicking on the top menu's Project, Add Reference, Extensions button and checking office which is now (14.0).
If you are not able to find PIA for Office 2013 then follow these steps:
Click on Solution Explorer in Visual Studio
Right click on your project name (not solution name)
Select 'Manage Nuget packages'
Click on Browse and search for PIA 2013, choose the shown PIA and click on Install.....
And you are done.
I have the same trouble. I went to Add references, COM tab, an select Microsoft Office 15.0 Objetct Library. Ok, and my problem ends.
part of my code is:
EXCEL.Range rango;
rango = (EXCEL.Range)HojadetrabajoExcel.get_Range("AE13", "AK23");
rango.Select();
// EXCEL.Pictures Lafoto = (EXCEL.Pictures).HojadetrabajoExcel.Pictures(System.Reflection.Missing.Value);
EXCEL.Pictures Lafoto = HojadetrabajoExcel.Pictures(System.Reflection.Missing.Value);
HojadetrabajoExcel.Shapes.AddPicture(#"D:\GENETICA HUMANA\Reportes\imagenes\" + Variables.nombreimagen,
Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue,
float.Parse(rango.Left.ToString()),float.Parse(rango.Top.ToString()), float.Parse(rango.Width.ToString()),
float.Parse(rango.Height.ToString()));
I faced the same problem when i tried to open my old c# project into visual studio 2017 version. This problem arises typically when you try to open a project that you made with previous version of VS and open it with latest version.
what i did is,i opened my project and delete the reference from my project,then added Microsoft outlook 12.0 object library and Microsoft office 12.0 object libraryMicrosoft outlook 12.0 object library
In my case when I added "Microsoft Excel Object Library" and "Microsoft Office Object Library" from Reference->COM then the reference error goes away.
