Creating UserForms
You can’t use Excel very long without being exposed to dialog boxes. Excel,
like most Windows programs, uses dialog boxes to obtain information,
clarify commands, and display messages. If you develop VBA macros, you
can create your own dialog boxes that work very much like those that are built
into Excel. These dialog boxes are known as UserForms.
Why Create UserForms?
Some macros that you create behave exactly the same every time that you execute
them. For example, you may develop a macro that enters a list of your sales
regions into a worksheet range. This macro always produces the same result and
requires no additional user input. You may develop other macros, however, that
perform differently under different circumstances or that offer options for the
user. In such cases, the macro may benefit from a custom dialog box.
The following is an example of a simple macro that makes each cell in the
selected range uppercase (but it skips cells that have a formula). The procedure
uses VBA’s built-in StrConv function.
Sub ChangeCase()
For Each cell In Selection
If Not cell.HasFormula Then
cell.Value = StrConv(cell.Value, vbUpperCase)
End If
Next cell
End Sub
This macro is useful, but it can be improved. For example, the macro would be
more helpful if it could also change the cells to lowercase or proper case (only the
first letter of each word is uppercase). This modification is not difficult to make,
but if you make this change to the macro, you need some method of asking the
