Courses - Microsoft Access 313
Description: Advanced Access
Running Time: 72 minutes
Pre-Requisites: Access 312 very strongly recommended
Previous Lesson: Access 312
Next Lesson: Access 320
Main Topics: Product Category Form, Filter, Zoom, Macro, Convert to VBA, Job Cost, Split DB
Versions: This course is valid for Access 2000 through 2003. If you are using Access 2007 or 2010, you will still benefit from this course. You will find that the concepts are the same, but there are cosmetic differences between the versions.

We'll begin by creating a Product Category Master Form where we can see a list of product categories, and then next to it a list of products in that category. These will both be in subforms on the main Master form. When you click on a category, it will update the other subform and show you just the products in that category. Then we'll add the ProductF form below those, and the product details will be shown down below - three forms in one.

 

Next, I want to be able to select a Category on my order form, and then have the product combo box list filter its results based on that selection by rewriting the SQL RowSource in the combo box.

 

Next we'll see how to automatically Zoom in to fields when they receive the focus (like a notes field) or if you double-click on them. I'll teach you how to create a Macro and then convert it into VBA code so you can figure out all kinds of new stuff.

We'll see how to hide items on our Invoice - like put cost-only products or services on an invoice and hide them from the customer (but still calculate them in our Job Costs). Our invoices are also looking really cool by this point.

 

Finally, we'll split the database intro front-end and back-end files as we did back in Access 307, but this time we'll walk through it in more detail, and I'll discuss the ramifications of sharing your database with other users, and over a local area network.

Student Interaction: Microsoft Access 313

Richard on 1/1/2008:  Access 313 covers making a Product Category table and form; a Master Form that shows all of the categories - you click on a category to show all of the products in that category on a second subform - then you click on the product to show the product details in a third subform; making a product category combo box on the order form that will filter the long list of products and automatically open it for us; automatic zoom into a field using VBA code; how to create a macro and then convert the macro to VBA code; how to hide specific items from your invoices so customers can't see them (if you need to add items for job costing); finally we'll split the database and go into database sharing in more detail.
 Twila Mitchell on 9/16/2008: What I really need is an easy way to print out a word document from vba. For instance, I have a policy that is over 60 pages long. Only page 1 and page 4 have information needed from my database so I would like to make a button that prints a report that is page 1 then will print a word document which will give me pages 2 and 3. Then I will print a report that is page 4 and finally, I will print a different word document that gives me pages 5 through the end.

I can't find information anywhere that helps me. Can we include this in a future class?

Richard Rost on 9/17/2008: Twila, what you need is AUTOMATION. It's a way of controling one MS Office application from another. You can use Automation, for example, to open a Word document and print it from your Access database, or open Outlook and send an email. YES, I will be covering Automation in a future class.
  on 3/5/2009: Your lessons are very helpful for me,a beginner.
Currecy$ is shown in UnitPrice of ProductCombo. How can I apply currency to a field in Combobox.
Thank you.

Richard Rost on 3/6/2009: Currency format in a combo box: The easiest thing to do is to format your field as CURRENCY type in a query and then use that query to feed your combo box. Or you can use the Format function to manually force it to Currency.
Richard on 11/5/2009: Here is some information from Microsoft's web site on the benefits of splitting your database:

Benefits of a split database

The benefits of a split database include the following:

* Improved performance The performance of the database usually improves significantly because only the data is sent across the network. In a shared database that is not split, the database objects themselves — tables, queries, forms, reports, macros and modules — are sent across the network, not just the data.

* Greater availability Because only the data is sent across the network, database transactions such as record edits are completed more quickly, which leaves the data more available to edit.

* Enhanced security If you store the back-end database on a computer that uses the NTFS file system, you can use NTFS security features to help protect your data. Because users access the back-end database by using linked tables, it is less likely that intruders can obtain unauthorized access to the data by stealing the front-end database or by posing as an authorized user. By default, Windows XP, Windows Vista, and Windows Server 2003 use the NTFS file system. If you are not sure what file system your file server uses, ask the system administrator. If you have administrator privileges on the file server, you can run the msinfo32 command to determine the file system yourself.

How do I use msinfo32 to check the file system?
1. Click the Start button, and then click Run.
2. In the Run dialog box, type msinfo32 and then click OK.
3. Under System Summary, click the plus symbol next to Components.
4. Under Components, click the plus symbol next to Storage, and then click Drives. The dialog box displays information about the available drives in the panel on the right.

* Improved reliability If a user encounters a problem and the database closes unexpectedly, any database file corruption is usually limited to the copy of the front-end database that the user had open. Because the user only accesses data in the back-end database by using linked tables, the back-end database file is much less likely to become corrupted.

* Flexible development environment Because each user works with a local copy of the front-end database, each user can independently develop queries, forms, reports, and other database objects without affecting other users. Similarly, you can develop and distribute a new version of the front-end database without disrupting access to the data that is stored in the back-end database.

Terry Hopper on 11/10/2009: When controlling a form from a form, can this be done with a list box as well? I would like to use a list box in place of the 'ProductCatagoryF' but have the same effect on the 'ProductListF'.
Richard Rost on 11/11/2009: Terry, sure. You would just need to use an AfterUpdate event for the list box, and refer to the list box value.
Terry Hopper on 11/11/2009: That is what I thought, but it's not working.
Here is my code...
Forms!CustomerCenterF!CompanyInformationF.Form.RecordSource = "SELECT * FROM CompanyT WHERE CompanyID=" & CompanyID

What am I not getting?
I have the company list with the id hidden (0") and I am referencing the form by name & property of that form. Sorry, just don't get it.

Richard Rost on 11/13/2009: That should work. Make sure everything (form, fields, etc.) is spelled right. Aside from that, I'd have to look at your database to tell you for sure.
Terry Hopper on 11/18/2009: Regarding the Zoom property. Can you make a button to Zoom into a field like notes but use the button as an option?
Richard Rost on 11/19/2009: Terry, I don't understand your question. Do you mean the SHIFT-F2 Zoom feature? Yes, you can control that with a button. There is a VBA command for it: DoCmd.RunCommand acCmdZoomBox
Terry Hopper on 12/4/2009: I have been working with this for weeks (11/14/09) and it still doesn't work. I have a EmployeeList box with EmployeeID, Active, FName & LName. The code is...

Private Sub lstEmployees_AfterUpdate()

On Error Resume Next

Forms!frmEmployeeCenter!sfrmEmployeeContact.Form.RecordSource = _
"SELECT * FROM qryEmployees WHERE EmployeeID=" & EmployeeID

End Sub

And I can't seem to figure it out. I have watched the video at least a half a dozen times and tried all different names for the fields to update.
Please help.

Richard Rost on 12/14/2009: Terry, your code looks fine. I'd have to see your database to tell you for sure why it's not working. You might want to try putting the full name of the EmployeeID in the code to...

...WHERE EmployeeID=" & Forms!MyForm!EmployeeID

If that doesn't work, let me know.

Or... is your listbox lstEmployees the field that contains your EmployeeID? If so, you need to say:

...WHERE EmployeeID=" & Forms!MyForm!lstEmployees

I'll bet that's it... unless EmployeeID is a separate field on that form.

Relja Koprolcec on 1/24/2013: Hey,I have just finisher 313 class and am ready for 314.Let me know if you already produced the alleged lesson.Regards Relja

Reply from Richard Rost:

Nope. There is no 314. The next lesson in the series would be 320.

Relja K on 1/24/2013: Great! So I need to get along with record sets next couple of months!

Reply from Richard Rost:

Yeah, it's not JUST recordsets. That's the main focus, but we build an order entry / invoicing system that's really cool. Lots of new techniques covered in it.

James Gray on 1/25/2013: Richard,

Does the size limitation of Access databases include the data files or just the size of the front end?

Reply from Richard Rost:

The 2 GB limit is PER FILE (MDB or ACCDB). BUT, you can effectively increase that by moving tables to another file and then linking them in.
