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…
There are cases where a table’s primary key is referred to often in the code. In fact, it might have some special meanings in code.

It is common to create a big wall of declaration in a module such as this: While the code will compile and work fine, the discoverability and naming of the module level variables does become difficult and unwieldy. To help cut down on this ambiguity, it is recommended to create a private user-defined type instead….
A common programming mistake is to hard-code literals that corresponds to some property. That is particularly true with certain controls like tab controls & pages. The tab control exposes a property that indicates the current tab and the pages contains a property that indicates its position in the tabs of the control. Thus, it’s common…
