[excel] How to suppress Update Links warning?

I'm trying to write a script that opens many Excel files. I keep getting the prompt:

This workbook contains links to other data sources.

I want to keep this message from appearing, so that my script can just automatically go through all the workbooks without me having to click Don't Update for each one. Currently I'm using the following:

function getWorkbook(bkPath as string) as workbook

Application.EnableEvents=False
Application.DisplayAlerts=False
getWorkbook=Workbooks.Open(bkPath,updatelinks:=0,readonly:=false)

end function

However, the message is still appearing. How can I suppress it?

EDIT: It appears that this message is coming up for workbooks that have broken links; I wasn't seeing the This workbook contains one or more links that cannot be updated message because I'd set DisplayAlerts to false. The workbooks are linked to equivalent files in a folder on our Windows server, so when the matching file is deleted from that folder (which happens as part of our business flow), the link breaks. Is it possible to suppress the warning when the link is broken?

Also, I'm using Excel 2010.

(I don't have enough rep points to add a comment, but I want to add some clarity on the answers here)

Application.AskToUpdateLinks = False is probably not what you want.

If set to False, then MS Excel will attempt to update the links automatically it just won't prompt the user beforehand, sorta counter-intuitive.

The correct solution, if you're looking to open a file without updating links should be:

Workbook.Open(UpdateLinks:=0)

Excel 2016 I had a similar problem when I created a workbook/file and then I changed the names but somehow the old workbook name was kept. After a lot of googling... well, didn't find any final answer there...

Go to DATA -> Edit Link -> Startup Prompt (at the bottom) Then choose the best option for you.

UPDATE:

After all the details summarized and discussed, I spent 2 fair hours in checking the options, and this update is to dot all is.

Preparations

First of all, I performed a clean Office 2010 x86 install on Clean Win7 SP1 Ultimate x64 virtual machine powered by VMWare (this is usual routine for my everyday testing tasks, so I have many of them deployed).

Then, I changed only the following Excel options (i.e. all the other are left as is after installation):

• Advanced > General > Ask to update automatic links checked:

• Trust Center > Trust Center Settings... > External Content > Enable All... (although that one that relates to Data Connections is most likely not important for the case):

Preconditions

I prepared and placed to C:\ a workbook exactly as per @Siddharth Rout suggestions in his updated answer (shared for your convenience): https://www.dropbox.com/s/mv88vyc27eljqaq/Book1withLinkToBook2.xlsx Linked book was then deleted so that link in the shared book is unavailable (for sure).

Manual Opening

The above shared file shows on opening (having the above listed Excel options) 2 warnings - in the order of appearance:

WARNING #1

After click on Update I expectedly got another:

WARNING #2

So, I suppose my testing environment is now pretty much similar to OP's) So far so good, we finally go to

VBA Opening

Now I'll try all possible options step by step to make the picture clear. I'll share only relevant lines of code for simplicity (complete sample file with code will be shared in the end).

1. Simple Application.Workbooks.Open

Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"

No surprise - this produces BOTH warnings, as for manual opening above.

2. Application.DisplayAlerts = False

Application.DisplayAlerts = False
Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"
Application.DisplayAlerts = True

This code ends up with WARNING #1, and either option clicked (Update / Don't Update) produces NO further warnings, i.e. Application.DisplayAlerts = False suppresses WARNING #2.

3. Application.AskToUpdateLinks = False

Application.AskToUpdateLinks = False
Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"
Application.AskToUpdateLinks = True

Opposite to DisplayAlerts, this code ends up with WARNING #2 only, i.e. Application.AskToUpdateLinks = False suppresses WARNING #1.

4. Double False

Application.AskToUpdateLinks = False
Application.DisplayAlerts = False
Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"
Application.DisplayAlerts = True
Application.AskToUpdateLinks = True

Apparently, this code ends up with suppressing BOTH WARNINGS.

5. UpdateLinks:=False

Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx", UpdateLinks:=False

Finally, this 1-line solution (originally proposed by @brettdj) works the same way as Double False: NO WARNINGS are shown!

Conclusions

Except a good testing practice and very important solved case (I may face such issues everyday while sending my workbooks to 3rd party, and now I'm prepared), 2 more things learned:

1. Excel options DO matter, regardless of version - especially when we come to VBA solutions.
2. Every trouble has short and elegant solution - together with not obvious and complicated one. Just one more proof for that!)

Thanks very much to everyone who contributed to the solution, and especially OP who raised the question. Hope my investigations and thoroughly described testing steps were helpful not only for me)

Sample file with the above code samples is shared (many lines are commented deliberately): https://www.dropbox.com/s/9bwu6pn8fcogby7/NoWarningsOpen.xlsm

Original answer (tested for Excel 2007 with certain options):

This code works fine for me - it loops through ALL Excel files specified using wildcards in the InputFolder:

Sub WorkbookOpening2007()

Dim InputFolder As String
Dim LoopFileNameExt As String

InputFolder = "D:\DOCUMENTS\" 'Trailing "\" is required!

LoopFileNameExt = Dir(InputFolder & "*.xls?")
Do While LoopFileNameExt <> ""

Application.DisplayAlerts = False
Application.Workbooks.Open (InputFolder & LoopFileNameExt)
Application.DisplayAlerts = True

LoopFileNameExt = Dir
Loop

End Sub

I tried it with books with unavailable external links - no warnings.

Sample file: https://www.dropbox.com/s/9bwu6pn8fcogby7/NoWarningsOpen.xlsm

I wanted to suppress the prompt that asks if you wish to update links to another workbook when my workbook is manually opened in Excel (as opposed to opening it programmatically via VBA). I tried including: Application.AskToUpdateLinks = False as the first line in my Auto_Open() macro but that didn't work. I discovered however that if you put it instead in the Workbook_Open() function in the ThisWorkbook module, it works brilliantly - the dialog is suppressed but the update still occurs silently in the background.

 Private Sub Workbook_Open()
    ' Suppress dialog & update automatically without asking
    Application.AskToUpdateLinks = False
End Sub

Hope to give some extra input in solving this question (or part of it).

This will work for opening an Excel file from another. A line of code from Mr. Peter L., for the change, use the following:

Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx", UpdateLinks:=3

This is in MSDS. The effect is that it just updates everything (yes, everything) with no warning. This can also be checked if you record a macro.

In MSDS, it refers this to MS EXCEL 2010 and 2013. I'm thinking that MS EXCEL 2016 has this covered as well.

I have MS EXCEL 2013, and have a situation pretty much the same as this topic. So I have a file (call it A) with Workbook_Open event code that always get's stuck on the update links prompt. I have another file (call it B) connected to this one, and Pivot Tables force me to open the file A so that the data model can be loaded. Since I want to open the A file silently in the background, I just use the line that I wrote above, with a Windows("A.xlsx").visible = false, and, apart from a bigger loading time, I open the A file from the B file with no problems or warnings, and fully updated.

Open the VBA Editor of Excel and type this in the Immediate Window (See Screenshot)

Application.AskToUpdateLinks = False 

Close Excel and then open your File. It will not prompt you again. Remember to reset it when you close the workbook else it will not work for other workbooks as well.

ScreenShot:

EDIT

So applying it to your code, your code will look like this

Function getWorkbook(bkPath As String) As Workbook
    Application.AskToUpdateLinks = False
    Set getWorkbook = Workbooks.Open(bkPath, False)
    Application.AskToUpdateLinks = True
End Function

FOLLOWUP

Sigil, The code below works on files with broken links as well. Here is my test code.

Test Conditions

1. Create 2 new files. Name them Sample1.xlsx and Sample2.xlsx and save them on C:\
2. In cell A1 of Sample1.xlsx, type this formula ='C:\[Sample2.xlsx]Sheet1'!$A$1
3. Save and close both the files
4. Delete Sample2.xlsx!!!
5. Open a New workbook and it's module paste this code and run Sample. You will notice that you will not get a prompt.

Code

Option Explicit

Sub Sample()
    getWorkbook "c:\Sample1.xlsx"
End Sub

Function getWorkbook(bkPath As String) As Workbook
    Application.AskToUpdateLinks = False
    Set getWorkbook = Workbooks.Open(bkPath, False)
    Application.AskToUpdateLinks = True
End Function
