Hi Experts,

I am attaching details of an issue I am having with using the Foirmat Function in Access 2016 Runtime.

Although one of the queries provides a workable solution it doesn't provide the desired display with the Team Name Left Zero filled.

Could you please take a look at this issue and advise if there is a way to display the Team Id at the left end of the display with leading zeros?

Thanks,
Bob C.

Hi John,

I'm not sure what you are asking.

If it is why this is different between the two queries (Q45221TeamIdName versus Q45221TeanIdName) it is because I made a typo which doesn't affect the actual operation.

Thanks,

Ok then...
I must say i am not sure what is the issue
Using Format should be enough
Format(SomeValue,"000") should cover all numbers till 999...if your number is greater then you need more zeroes...

Hi John,

The issue is that Access 2016 Runtime does not work correctly with the Format Function.

Note that if you try it with Access Full Version with the /Runtime switch it works correctly.

Therefore I believe that I have identified a bug in the Microsoft Access 2016 Runtime software version as follows which appears to be the latest version.  I also note that this is the same file that is specified for Access 2019 Runtime..
- accessruntime_4288-1001_x86_en-us.exe

I have also determined since opening this question that it also doesn't work correctly with the following two additional Funcrtions.
- CStr(InputFieldLong).
- CLng(InputFieldString).

So the question is whether or not there is something I can use in their place?

Thanks,
Bob C.

Interesting that format doesn't return correctly formatted string in Runtime...i don't know if its reported by anyone
What you can do is to count the Len of the CStr(InputFieldLong) and work with this
For example you want 6 digits
Len(CStr(InputFieldLong)) = 3
FinalOuput ="000" & CStr(InputFieldLong)
so if CStr(InputFieldLong) = "123" this would result
FinalOuput ="000" & "123"
000123

Your problem is more likely a missing reference. The full version may correct this, while the runtime won't.
So, go to menu Tools, References and double-check. Remove any reference not needed and correct any marked as MISSING.

Hi Gustav,

I am familiar with 'References' and this was my first thought.  I'm attaching my documentation in this regard, much of which was developed in conjunction with EE Experts.

The problem with this is that I can't see any way to check the References in the Access 2016 Runtime since there is no Ribbon selections other than File and it isn't accessable through the File option.

Is there a way to get at it?

Thanks,

You can create a test database having the same references set, and then - for example called from an AutoExec macro - code like this:

Are you sure you need the VBA Extensibility reference? That generally is used for working with VBA objects in code (i.e. changing a Module or something like that)? I don't think I've ever deployed an Access database with that reference.

Are you sure you need the ADO Recordset library? What are you doing with ADO? If you're just opening connections and recordsets, you almost certainly don't need that library.

The Scripting runtime can sometimes be blocked by virus engines.

Office references can cause troubles if your machine is running a version higher than the target machines.

Assuming you're using early binding, you can determine if your database needs a reference by doing this:

1. Compile the code. If any errors occur, fix them and continue compiling until the menu item is disabled.
2. Remove the reference. BE SURE to make note of the location of the reference in case you need to restore it.
3. Delete the reference.
4. Compile again. If you have no errors, you almost certainly do not need that reference.

Besides all the nice referencing code posted by Gustav how about going simple
Just create a small test application that formats a number...test it on all cases..if it fails on Runtime then use another computer or VM to recheck it.
Post back the results.

Hi Experts,

Thanks for all the great things to try.  It will take me some time!

John:
I'm going keep your suggestion to 'Create A Small Test Application' for possible future analysis although I can probably use the same one as for Gustav's suggestion.

Scott:
I'm a little leary about doing this however it is worth a try.

Since I don't really have any knowledge with regard to References and what they are doing it is hard for me to answer your questions, however I will try:
- VBA Extensibility.  I don't have any idea what this does and therefore the potential impact of removing it.
- ADO Recordset Library.  Mostly I am opening / closing Databases / Recordsets.  However I do have code that does relinking.
- Early Binding.  I use Late Binding to import Excel Files as I have worked with EE Experts and determine that this is my best option.
 
Gustav
Thanks for the suggestions / code.  I want to try it but I'm not sure about how to actually do it.  What are .bas files?  I'm familiar with DOS. bat files.

If I understand correctly all I need is a Test Database containing the References.  That I understand.

What I don't understnad is:
- Within it I would have two 'Menu Items' to 'run' the two .bas files.  Is this correct?
- If so what would the code look like to run them?  I haven't done this before.

Thanks All,
Bob C.

Removing the references as a test has no impact. If there are problems, you simply reinstate the reference. As mentioned earlier, all you do is compile your code (to ensure it works BEFORE removing the reference), and the remove the reference and recompile. After the recompile, if you have no issues then you can be sure you don't need that reference, and you can remove it. All in all, you are waaaay ahead of the game if you remove any references you don't actually need.

Of course, you should make a backup of your database first.

The basics for Access references are these:

Visual Basic for Applications
Microsoft Access 16.0 Object Library
OLE Automation
Microsoft Office 16.0 Access database engine Objects

When you create a new Access database, Access adds those references (the numbers may be different depending on the version of Office you're running). The others are ones you've added for one reason or another.

If you're using Late Binding with Excel, then you most likely don't need the Excel reference. One of the major concepts of Late Binding is that your code is NOT version-dependent. It's somewhat pointless to use Late Binding but keep the reference in place.

As mentioned earlier, it is very rare that the VBA Extensibility library is needed in a production deployment. That library is typically only used with developer addins and such, things that actually interact with code modules and such.

Hi Gustav,

Thanks for the update.

A couple of questions:
- Once they are 'imported', am I correct that then all I do is create a Button somehwere to run each of them?
- Is there any disadvantage to keeping this functionality in the application (hidden from Users) ?
- Do I need anything else in the Test Database other than the References and code to run the two Modules?
- Can I simply do this in a copy of my latest .accdb?
- Can I run these Modules on each PC that I use to develop / test?

Thanks,

- As noted, the simplest is to call it from an AutoExec macro.
- You can keep it - to warn the user if anything is not as expected.
- No.
- Yes, but I would create a test application for a start.
- Yes.

And, as mentioned by Scott, in your application, remove any you don't know what does, compile the code, and - when success - run a full test of the application and correct any error that may be caused by a missing reference by adding the relevant reference back.

Hi Gustav,
1. What is an AutoExec Macro?  I don't use Macros at all in the application.
2. Am I correct that you are suggesting that it always run whenever the application is started?  If so are any overhead issues?

The overhead to run this at each launch is absolutely minimal.

Hi Gustav,

Thanks for the update / code.

Late yesterday I proceeded with removing / re-adding the References.  At this point I have 5 setup and testing of the original problems has indicated that they have all been solved.  I need to continue with testing the whole application to ensure there arn't any more required.

I'll provide an update when the testing is complete.

Hi Experts,

Based on the majority of your suggestions I concentrated on the VB References.

I have been able to obtain a solution via the following basic steps.
On my Development PC (64 Bit) with Access 2016 Plus
01. Opened the FE Database.
02. Removed the BE Linkage to my 5 BE Datases by using the Convert To Local Table function.
03. Opened the Visual Basic > Tools > References and deleted all of the References not in use.
04. Closed the FE Database.
05. Opened the FE Database and added a couple of Referecces back in resulting in the 4 listed below.
- Visual Basic For ApplicationsC:\Program Files (x86)\CommonX86\Microsoft Shared\VBA\VBA7.1\VBE7.DLL  
- Microsoft Access 16.0 Object Library   C:\Program Files (x86)\Microsoft Office\root\Office 16\MSAC.OLB
- Microsoft Office 2016.0 Access database engine Object Library  C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE16\ACEDAO.DLL
- Microsoft Office 16.0 Object Library  C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE16\MSO.DLL
06. Tested the FE to ensure that all of the issues were corrected.
07. Split the FE Database Into one BE Database.
08. Create my 5 BE Databases from the single BE Database and linked the FE Database to them.
09. Tested the FE Database.
10. Created an Install EXE using Advanced Installer.

On my Test PC (32 Bit) with Access 2016 Runtime.
01. Ensured that any previous installation had been removed.
02. Ensured that Access 2016 Runtime was installed.
03. Completed the installation from the Install EXE.
04. Tested the installation without incident.

Thanks again to all of you for your asistance with solving this issue.
