It is common to create a big wall of declaration in a module such as this:
|
1 2 3 4 5 |
Private strCompanyName As String Private dteOrderDate As Date Private lngOrderID As Long Private objEmail As Object Private objOutlook As Object |

VBA is quite very loose in what it deems “truthy” and “falsy”. For example, this procedure can produce surprising result:
|
