Compile Error: Can't find project or library (missing Add-in)

[Guest]

I have built a workbook that call subroutines in an add-in (.xla). If the
workbook is run on another PC for the first time I get the above compile
error, because the add-in is missing and my workbook code crashes. Is it
possible to check in a macro that the add-in is present and exit gracefully
(perhaps displaying a message saying the Add-in is missing)?

If you've set a reference in your workbook to the add-in there is no way to
trap an error if it is not present, as far as I know. But if you're running
add-in code in some other way (like using RUN) you could check whether the
add-in is open like this first:

Function AddinPresent() As Boolean
Dim WBName As String
On Error GoTo NotPresent
WBName = Workbooks("YourAddin.xla").Name
AddinPresent = True
NotPresent:
End Function

Jim,

Thankyou for the reply. I have set a reference to a .xla, I have not used
the RUN method before, if I did what are the disadvantages if I changed
everytrhing to use RUN? (I presume you are talking about a .xlm?) I have no
idea how to even create one of these.

Life wasn't meant to be easy was it?

I don't know of any disadvantage except that it's a little more cumbersome
to call a sub via Run than directly. In theory Run is a little slower but I
don't see a difference as a practical matter.

I don't know what you mean by "xlm". All I'm saying is replace a direct
call to the add-in's sub:

SubInXLA

with

Run "MyAddin.xla!SubInXLA"

Of course this requires that the add-in is open in Excel.

It will take you only a few seconds to switch one or two call and test how
it works for you. check out the Run method for moe on it.

Jim,

Thank you again for your reply. But I am still having problems:

This is the main workbook:

Option Explicit
Option Private Module
Public Const DCMaster = "Customer Data Collect Master v6.37.xla"

Sub Auto_Open()
If AddinPresent Then
Application.Run DCMaster & "!test" <----- This says it can't find
the macro
Else
MsgBox "Addin Not Present"
End If
End Sub

Function AddinPresent() As Boolean <----- This works great thankyou
Dim WBName As String
On Error GoTo NotPresent
WBName = Workbooks(DCMaster).Name
AddinPresent = True
NotPresent:
End Function

This is the macro in the .xla:

Public Sub test()
MsgBox "test"
End Sub

Hi Tefor,

Application.Run DCMaster & "!test" <----- This says it can't find

Look at the syntax suggested by Jim and look at the Run method in VBA help.

Try:

Application.Run "DCMaster.xla!test"

 

[Norman Jones]

Hi Tefor,

Please ignore my previous post; I did not see your public constant.

Try instead changing:
to:
Public Const DCMaster = "'Customer Data Collect Master v6.37.xla'"


The additional single quotes are required because of the spaces in the file
name.

Norman/Jim,

Yes I worked that bit out, found it another thread, and you were spot on. I
was just coming back to let Jim know and saw your reply.

Ok, my next problem in converting my files to use RUN, is calling a macro
from a command button. Originally the button said:

'Customer Data Collect v6.37 test.xls'!Menu_New_Site

I tried changing it to the .xla as per the RUN:

'Customer Data Collect Master v6.37.xla'!Menu_New_Site

In both cases it says it can't find the macro, any ideas?

 

[Norman Jones]

Hi Trefor,

With the XLA file open, try:

Menu_New_Site

Norman,

Interestingly after my last edit (to 'Customer Data Collect Master
v6.37.xla'!Menu_New_Site), it reverted to your suggestion anyway. And I get a
slighty different error message but essentially the same problem.

Hi Trefor,

And I get a slighty different error message but essentially the
same problem.

What error message do you get?

I created an addin and named it:
Customer Data Collect Master v6.37.xla'

I added a macro and named it: Menu_New_Site; I assigned the macro to the
button using Menu_New_Site as the macro reference. Clicking the button the
macro (which comprised a banal message) ran as expected.

 

[Guest]

Error message is:

"The macro 'Menu_New_Site' cannot be found"

 

[Norman Jones]

Hi Trefor.

Is the addin loaded?

Are you sure that the macro name is spelt correctly?

Is it possible that the macro is present more than once, perhaps in
different modules in the addin.

Norman,

I have checked everything you suggested and all appears to be in order.

As a final check, I added a reference (VBE - Tools > References) and the
button's work fine. I went back in and removed the Reference and it stopped
working.

Perhaps as a variation to my original question, is it possible to code the
adding and removing of a Reference? I now this is a bit defeatist but it all
seemed to work fine with a reference added.

Before I had a permanent Reference which was fine as long as the reference
was actually there. Now with all this playing I have managed to check for the
xla, load it and use with RUN's from the main workbook. If my main program
can add the reference and remove it before closing/saving I will have
achieved my original goal.
