How to call a VBA-macro in another MS Word document? - vba

in MS Excel I have been distributing a xls-file that contains a macro. From the users "random" current open workbook I have successfully been calling this macro by telling Word in which file to look for it. Like this, when the user clicks a button on the ribbon:
C:\\"'MyExcelFileWithTheMacro.xls'!MyMacroName"
Can I do the same in MS Word?
That is, to call a macro in a Word-file located in any given folder from an instance of Word that has not opened that file?
I have tried, of course, but Word keeps saying it can't find the macro.
The reason I want to do it this way is that it is makes for easy distribution and updating of the macro. Next up is signing the macro. I hope it can be done when doing things this way, but not sure.

No, it's not possible to call and run a macro in any Office application if the file that contains the macro is not loaded in the application interface.
That being said, if you place the macro in a *.dotm template and have the user put the template in the STARTUP folder used by the Word application, then Word will load the template as an "Add-in". And in that case you should be able to access the macro.
Or, if you don't want it in the Startup folder and you have code that automates the Word.Application, anyway, then that code can load the *.dotm as an "Addin", which should make the macro available (and remove it when you're done with it). Research Application.Addins.Load and Addin.Installed in the Word language reference as well as on-line for examples.

Prevent Word macro in Normal.dotm for some templates

I have a Normal.dotm file that contains an AutoNew macro.
This macro is automatically executed each time a new document is created using any other template.
Is there any way I can prevent this automatic behavior for a specific template?
I have a Word VSTO add-in running, so I can hook into Word's events, but so far I havn't found a way to prevent this.
I do know that I can prevent macro execution when using templates programmatically, for example like this:
' Disable auto-macros before opening document
wordApplication.WordBasic.DisableAutoMacros(1)
' Open document
newWordDocument = wordApplication.Documents.Open(template.FullName, ConfirmConversions:=False, [ReadOnly]:=True, AddToRecentFiles:=False, Revert:=True)
' Re-enable auto-macros
wordApplication.WordBasic.DisableAutoMacros(0)
But this solution doesn't work when the user uses a Word template from Windows explorer or the Open-dialog in Word, since in those cases I can't execute code before it's too late already.
Or can I?
I hope someone has a trick for me :-)

Edit: While trying different solutions, I discovered something that might help others in similar situations, though unfortunately it doesn't help me.
It seems that if a template contains a module containing an AutoNew (or AutoOpen for that matter), that local macro is executed instead of the one in Normal.dotm.
Example:
Normal.dotm contains the following macro:
Sub AutoNew()
MsgBox "Normal.dotm"
End Sub
Test.dotm contains the following macro:
Sub AutoNew()
MsgBox "Test.dotm"
End Sub
When executing Test.dotm the message "Test.dotm" is displayed, while the message "Normal.dotm" is not displayed.
If the AutoNew macro is removed from the Test.dotm template, the message "Normal.dotm" is indeed displayed.
So it is possible to easily override the auto-macros.
The local versions of AutoNew and AutoOpen can even be empty subs that do nothing. It still works.
This is not possible in my case though, since the template I use is generated by code, and cannot contain macros (because adding macros to templates programmatically requires the user to manually activate the option "Trust access to the VBA project object model", and that's something I cannot ask my customers to do for all users. It's also a security risk.)
Based on the workaround described in the "Edit" part of the question - providing a template with "empty" Auto-macros - it's possible to use the Open XML SDK to create a template and add the VBA project to it in order to provide this functionality. This approach avoids the user needing to allow access to the VBA project on his installation. The only "macro security" that could be triggered is that for not allowing macros to run. But since the client uses macros, anyway, this should not be a major obstacle.
The simplest method is to create as much of the basic template as possible in the Word UI and use this as a starting point.
Since you're unfamiliar with the Open XML SDK, the next step would be to create one (or more) templates in the Word UI using the basic template as the starting point, saving under a different file name.
You can then use Open XML SDK Productivity Tool to see the code required to generate any one of these files, as well as, using the Compare tool, the code for converting the basic template to the derived version. This should give you a decent start with the SDK and it's object model. Once you get a feel for how the Open XML SDK works, if you're familiar with Word's object model, using that provided by the SDK is relatively straight-forward as an effort was made to make it correspond as closely as possible to the "COM" object model.
The VBA project can be added later, but you can also include it in the basic template. That would be the simplest approach.
Include this "starting point" basic template as part of your solution, installing it as part of the solution.
Within the AutoNew macro you can check the AttachedTemplate property. Only if it is a template where you want to apply the cleaning you can execute the respective macros.
Sub AutoNew()
If ActiveDocument.AttachedTemplate <> "Normal.dotm" Then
Exit Sub
End If
' rest of the macro
End Sub
If you don't control the Normal.dotm you can put an empty AutoNew macro in your own templates. As Word only executes the auto macro in the closest context, the macro in the Normal.dotm file would not be executed.
If you don't control the other templates either, you can tell your users to hold down the SHIFT key while creating a document. This prevents the execution of the auto macro.
Probably it is best, however, if you ask the owner of the other system to find another solution that does not rely on polluting the Normal.dotm file.

Normal.dotm equivalent in Excel for referencing the same single VBA code

Just curiosity.
The only way I know so far is to create an add-in with code, put it in some trusted directory and hope it opens when you need it. The drawback is that it sometimes does not open together with application (e.g. I have a custom UDF in the add-in, I use it in the worksheet and an error is what I get, because the addin hasn't started). For this I have a button on my ribbon which calls a sub in the addin which does nothing, but then the addin is activated the UDF works.
Is there any other efficient way to reference code in another workbooks, like in Word we have normal.dotm template?
Indeed, Excel DOES have a common code file, similar in concept to Word's normal.dotm. It is called Personal.xlsb. I use it myself for common functions that I need for several linked yet independent spreadsheets.
Using Personal.xlsb has some disadvantages too, so you'll have to decide if that works better than the Add-in approach. Note that Personal.xlsb works best when its just one person needing common functions across spreadsheets; its not well suited for multi-user access to the spreadsheets in an enterprise environment.
Some useful links are below to get started. Also just google search "excel Personal.xlsb" and you will find a lot more information:

To create an equalevant to normal.dot in Excel do this (at least ver. 2016):
Record a macro from the Developer tab (you likely have to enable this tab first)
This will create the file %appdata%\Microsoft\Excel\XLSTART\PERSONAL.XLSB which is Excel's equalevant to normal.dot
Now unhide the hidden workbook called "PERSONAL.XLSB"
Press Alt+F8 or Alt+F11 to edit the VBA code

Application.Dialogs(xlDialogSaveAs).Show

Standalone code for Excel

Can VBA code be written to perform actions on any Excel file?
When I create a project in Visual Studio, it asks for an Excel file to be linked to it. All the code that I write is in ThisWorkbook.vb and hence acts only on the Excel file linked to the project.
Ideally, I want a script that:
When the user double-clicks, he/she should be allowed to select an Excel file of choice for the actions to be performed on that file.
If the above is not possible, I'd at least like to invoke the VBA script from within an Excel file.
Basically, the VBA code should be independent of any Excel file.
I looked at VBScript, but the syntax for it seems to differ slightly.
You've mentioned Visual Studio, VBA, and VBScript. The solution I'm outlining works directly with VBA rather than Visual Studio or VBScript. (However, you might adapt Visual Studio (C# or VB) along the lines of what I'm outlining below.) Hope it's helpful, so here goes:
Here's what I do, and, it ultimately results in an .xlam Excel AddIn as #chris above has commented.
Overview
I start with ordinary .xslx workbook, to which I add a VBA project, making it an .xlsm. Then create some VBA Subs (macros). Then create some Excel QAT (Quick Access Toolbar) buttons for the workbook, which are bound to (i.e. they invoke) the VBA subs/macros. Then convert the workbook (with VBA in it) to an .xlam, which is an Excel AddIn. When you're all done, the buttons are accessible from any workbook (and the VBA code has access to any user workbooks as well as those originally in your .xlsm). Further, the workbook associated with the .xlam is invisible. So it just looks like you've added some buttons to the QAT that appear on all users .xlsx windows. The .xlam is pretty easy for users to install (though I provide a buttons to uninstall/reinstall/check version). You can upgrade an .xlam independently of users' workbooks; users' workbooks can thus be data only (.xlsx, no VBA).
Details
Write some Excel Subs you want to use later
You need to be aware that the buttons can only invoke macros (VBA Subs) without parameters, so the macros will have to check things like ActiveSheet and ActiveWorkbook and Selection to figure on what sheet the button was pressed, hence what user data to really operate on. (If you need to refer to your workbook with the VBA code in it, use “ThisWorkbook”). You should be aware that there can be naming conflicts, so try to name the parameterless subs with rather long names, such as MySomewhatUniqueProjectName_button1, etc…
Add Buttons to your .xlsm
Using Excel 2010 (I think this works with 2007 or later), I put workbook-specific buttons on the QAT part of the ribbon, which connect to macros (VBA subs) in the VBA code.
To do this, you from the Quick Access Toolbar customization drop down (the tiny down arrow at the very top row of the Excel window, the last icon from left to right) choose "More Commands…". When the “Customize Quick Access Toolbar” dialog box comes up, from the (2nd) "Customize Quick Access Toolbar:" heading (top to the right), choose "For XYZ.xlsm" from the dropdown instead of the "For all documents (default)". And from under "Choose Commands From:", use "Macros" (instead of “Popular Commands”) from the dropdown. Once you have those two things selected, you can move VBA subs from the left box to the right box using “Add >>”. Each so moved will become buttons visible in your QAT. As you’re doing this you can also edit the icon and text for the buttons, add a separator as needed (I always end with a separator in case other .xlam’s use the QAT). (Now is a good time to save this .xlsm.)
Convert the .xlsm into a .xlam
Then I convert the .xlsm to an Excel add-in, by merely saving it as an .xlam file. This will end up (1) hiding the workbook associated with the code you have (though it is still accessible to itself.). Further, now, (2) the (invisible, as now it's an .xlam) workbook will load whenever Excel is loaded. (To keep this fast for when users use Excel but don’t run my VBA code, I don't run any code when the .xlam is loaded, I only run code when a button is pushed.)
You can manage the AddIn using Excel’s AddIn manager. To update the AddIn, you have to use some trickery. While you can copy over it when Excel is not running, on the other hand, you cannot directly uninstall the AddIn, you can only disable it from Excel. But once disabled, you can delete the .xlam, and relaunch Excel, go to the AddIn manager to try to work with the (now gone) AddIn and you’ll get Excel saying it can’t find it, so do you want to delete it. Say yes, and it will be uninstalled.
FYI, Notes
I keep the .xlsm to edit later, but you can actually debug and edit the .xlam and later convert it back to an .xlsm with a minor bit of trickery: find its "ThisWorkbook" entry in VBA, and then the "IsAddIn" property, set to false, its workbook will suddenly appear and you can save as .xlsm, or edit its workbook and set the property back to true to resave as .xlam directly.)
Answer 1
You can do that in VB.Net too. Just make a regular project. (comment by #SLaks)
This worked for me very well and was exactly what I was looking for.
Answer 2
The very descriptive answer posted by #ErikEidt
I haven't tried this, but it seems like a good and alternative way of getting macros to work.

Excel VBA - Call macro using add in

I have added a toolbar menu for my macro, so I can just press the button and it runs my macro from any excel document. Every time I run the macro though, it opens the source file containing the macro. Is there a way that it won't open the source file and just run the macro? (even opening and closing wouldn't too much of an issue, but I'd prefer not opening it at all)
I haven't been able to find any information about this, so all help to get me started is appreciated.
You can't pull code out of the air to run it; Excel's going to have to open the file the code's stored in to run the code.
If I understand it correctly, you can create an Excel add-in from your code and have the add-in load automatically when Excel starts. Your code will always be available in that case.
This seems like a good place to start:
http://msdn.microsoft.com/en-us/library/aa140990(v=office.10).aspx
USE YOUR PERSONAL MACRO WORKBOOK
Open the VBEditor and find the module containing your macro.
Copy that code.
Now in the VBProject Panel on the left, locate your PERSONAL.XLS or PERSONAL.XLSB project. This is the project where you store macros you want available at all times. Add a module to that project and put your code into it.
Now update your "button" so that it points to the macro in that workbook and you're good to go.
On the off chance your PERSONAL.XLS project does not exist, use the macro recorder to record a "junk" macro and be sure to set it to "Store Macro In: Personal Macro Workbook"... that will create it for you the first time.

Using Word automation, is it possible to find out if the active document contains VBA code?

Using Word Automation, I want to save the active document programmatically. In Office 2007/2010, the document needs to be saved explicitly as "macro enabled" to preserve any VBA code in that document.
Rather than asking the user to choose, I would like my application to be able to determine if there is VBA code in the active document. Is that possible?
Yes this can be determined via the HasVBProject property. For example:
If ActiveDocument.HasVBProject = True Then
'Code to save as .dotm
Else
'Code to save as .dotx
End If
For those who might stumble upon this post later, it is worth noting that this code should be placed outside the document being tested for the presence of macros (otherwise it would detect itself). Two often-used options would be to access the code from an external application or from a template stored in Word's Startup folder.
