I am your instructor Richard Rost.In today's video, I'm going to show you how to deal with missing or broken references in your Access databases. Have you ever gone to start up your database, or you got a database file from a colleague or a friend of yours, and this happens? Boom. It says your database name, TechHelp Free Template in my case, or project contains a missing or broken reference to the file whatever. It says to ensure your database or project works properly, you must fix this reference. What is a reference? What is this file and how do I get rid of this error message? I will hit OK and the database loads up, but you'll notice right away some stuff does not work that should normally work. This is just a simple date field for example and it is not working. So what are references? If you got this database from someone else, chances are they used a third-party reference or a reference to a different file that is not normally part of Access. It could be something simple like an Acrobat Reader to view PDF files or an Outlook plugin to view and send emails. How do you find these different references? Go into Design View. Go to Form Design and in the Tools section, find this little guy here. It says View Code. That will bring up the VB Editor. Now right up top here on the Tools menu, you will see References. This is a long list of all kinds of different stuff that you can plug in to Access. This Outlook stuff, there is SharePoint stuff, you name it. There is a bunch of stuff in here and what is in here is completely dependent upon what is installed on your system. You may have some of this stuff, you may have none of this stuff. You should have some of this stuff. Some of the things are installed by default with Access, Visual Basic for Applications, Microsoft's Access 6.0 Object Library that comes with this version of Access. Yours might be different. As you can see right here, I'm missing something: HyperSnap 8. HyperSnap is a screen capture utility that I have on my system, and I intentionally broke this reference by renaming that file something else so that Access would cause this error message. This usually happens because someone else who gave you this file installed this component in their Access database to use it, but you do not have that file. You might not have HyperSnap 8 installed. You might not have Acrobat Reader installed, whatever. Or you might have it installed, but you might have a different version. You might have an older version of Access or an older version of Excel or whatever the plugin is for. This is one of the reasons why I really, really, really, really hate third-party references. I try to tell people whenever possible, use features that are built into Access. Avoid third-party plugins because you cannot guarantee that everyone else is going to have the same files and in the same locations. You might have installed HyperSnap in a different folder, for example. The good news is all you really have to do is uncheck that box, hit OK, and then restart your database. So I will shut it down and then open it back up again. I named it Missing References. Open it back up. The error message goes away and now look, that date field is working again. Missing references can cause any number of weird problems in your database. I got rid of that error message by simply removing the reference file, and now the database opens. Any features that are dependent upon that reference file are not going to work. So if I have some kind of a HyperSnap plugin in a form somewhere in my database, that is not going to work. But at least the rest of the database will open and you can use it, open the forms and reports and all the normal Access stuff. That is how you get rid of that error message. As far as getting that HyperSnap thing working again, all I have to do is go and rename that file that I just changed. If you do not have whatever application that person had installed and Access to begin with, it is just not going to work. You have to talk to them, get the same software installed, or find out whatever they did that you have to do to your computer to make that reference work. That is how you can get rid of the error message. That is how you can get into the database and that is it. I hope you learned something. We will see you next time. QuizQ1. What is the primary cause of a "missing or broken reference" error when opening an Access database from someone else?A. A corrupt Access database file B. A third-party reference or file used by the original creator that is missing on your system C. Too many fields in a table D. An expired Access license Q2. How can you access the References dialog in Access to see missing references? A. By right-clicking the database icon B. By opening the VB Editor from the Form Design Tools menu and selecting References from the Tools menu C. By opening the Options menu in Access D. By running a special macro Q3. What does a missing reference typically affect in your Access database? A. Only the look and feel of reports B. Any features that depend on that reference may not work correctly C. The database security settings D. It prevents any data from being stored Q4. What is the suggested way to resolve a missing reference error if you do not need the referenced feature? A. Ignore the message and keep using Access B. Reinstall Microsoft Office C. Uncheck the missing reference in the References dialog and restart the database D. Remove all code from your database Q5. Why does the instructor recommend avoiding third-party references in Access databases? A. They are too expensive B. You cannot guarantee that other users will have the same files or in the same locations C. Microsoft does not allow their use D. They slow down Access databases Q6. If you want to restore a missing reference related to a specific application like HyperSnap, what should you do? A. Rename the Access database file B. Reboot your computer several times C. Install or restore the missing application file as used by the database creator D. Delete and recreate all forms Q7. What is the likely outcome if you remove a missing reference but keep using the database? A. All third-party functions will be replaced with built-in Access functions B. Any features in the database that depend on that reference will not work C. The database will be permanently corrupted D. You will lose all of your data Q8. What is the first indication that a missing or broken reference exists when you open a database? A. The database opens without any notification B. You receive an error message about a missing or broken reference C. The computer reboots unexpectedly D.

SummaryToday's video from Access Learning Zone focuses on handling missing or broken references in your Access databases.Sometimes when you try to open a database, especially one you've received from someone else, you might be greeted with an error message stating that your project contains a missing or broken reference to a particular file. Access will warn you that in order for your database or project to work correctly, this reference must be fixed. To understand this, let's talk about what a reference actually is. References point to external libraries or files that your database uses to provide extra features beyond the standard ones built into Access. For example, someone might have added a reference to Acrobat Reader to deal with PDF files, or an Outlook library to handle emails. If you do not have these same files or libraries installed on your computer, Access will generate this error. When the database loads up after you dismiss the error, you'll often find that certain things don't work as expected. In this example, something as simple as a date field was malfunctioning because of the missing reference. To see which references your database is using, open the database in Design View, then go into the Visual Basic Editor. In the Tools menu, you'll find a section called References. This brings up a long list of available references that you can add to your project. The list you see depends entirely on which software and plugins are installed on your computer. Some references, like the core Access and VBA libraries, are included by default. Others, such as third-party plugins, might not be present. In my case, I had a missing reference to "HyperSnap 8," which is a screen capture tool I use. I broke the reference on purpose for this demonstration by changing the name of its file, so that Access would trigger the missing reference error. These problems usually occur when you get a database from someone who has added extra functionality through components you do not have installed. Even if you have a similar component, it might be a different version, or it might be installed in a different folder, causing Access to fail to find it. This is why I always try to avoid using third-party references in Access databases. Relying on built-in features is much safer because you know everyone running Access will have them. Using outside plugins or references can easily result in errors if someone else tries to use your database on a different computer setup. The solution to this problem is usually straightforward. In the References window, simply uncheck the box next to the missing reference and click OK. After closing and reopening your database, the error message should disappear. Any features in your database that depended on that missing reference, such as a form or report using HyperSnap, will not work until you restore the reference, but the rest of your database should function normally. If you ever need to get a specific feature working again, you'll need to make sure you have the same software installed as the person who created the database, and possibly adjust the file location or version if necessary. To sum up, that's how you resolve missing or broken references in Microsoft Access databases. This approach lets you clear the error, access your database, and restore basic functionality, even if some advanced features are dependent on files or components you do not have.
