VBA is quite very loose in what it deems “truthy” and “falsy”. For example, this procedure can produce surprising result:
|
1 2 3 4 5 |
If Me.MyBitField.Value = True Then 'It is true Else 'It is false End If |
At the first glance, it seems expected that if the bit field is set to 1, it would succeed. But in fact, it wouldn’t because True is equivalent to -1, not 1. Unless we…
In VBA, there are several features that allow us to do things that may not be checked at the compile time.

First we need to define what a state is. A state means that the object has variable(s) that may cause it to behave differently, depending on the content of the variables. As an example, the Forms collection is stateful:
|
1 |
Forms("SomeForm").Visible = False |
This is legal code and will compile but we can’t be assured that this will…
I’ve been seeing more and more people having problems with the Unrecognized Database Format when creating or modifying an Access 2007 (accdb) format database in Access 2010 and then trying to open it again in Access 2007. The issue appears to be that Access 2010 does not have its own file format. When you add a…
