Hardware matters. Invest in a faster PC and your Microsoft Access databases will run faster. Be alert for sellers packaging fast processors with minimal memory and a slow hard drive to keep prices low. Look at all aspects of the purchase when database speed is a priority. A faster hard drive is worth the investment…

I was working on a design for an Order Management Database, and one of the tasks I dealt with involved dynamically Enabling or Disabling one of the form’s Command Buttons’ using VBA. This gave me the idea for the present Access tip. The command button was located on a Customer Details form which had an Orders…
Once you have created an Access Database Application to be used by other people, it may well be important for you to prevent users from gaining access to any of its design features. By this I mean, you may not want users to modify your tables, forms and queries etc in design view (inadvertently or…
When you use code to refer to Excel (and other programs as well) you need to be careful not to use any code that does not refer back to the instantiated application object. If you do so then you will find that Access instantiates another Excel (or other program) object which is not visible to…
A number of objects may have extra properties or something where it might not exist for all instances. A good example might be finding Controlsource property on an Access.Control variable:
|
1 2 3 |
For Each ctl In Me.Controls Debug.Print ctl.ControlSource 'A potential error Next |
Not all controls have a ControlSource property and thus can fail to run. A common approach is to use OERN:
|
1 2 3 4 5 |
For Each ctl In Me.Controls On Error Resume Next Debug.Print ctl.ControlSource 'A potential error On Error GoTo 0 Next |
This will work…

In VBA, there are several features that allow us to do things that may not be checked at the compile time. In particular, it is possible to write several late-bound expressions which means that it can potentially contain run-time errors. One common misconception about late-binding is that it’s a matter of adding a reference and…
Custom functions work the same way as MS Access built-in functions such as DateAdd, DatePart and DSum, but are instead created ourselves as database developers. We do this by creating a public function with the VBA programming language and save it inside a global module within the database. Today I am going to explain how custom functions can be…
