POWER PROGRAMMING TECHNIQUE

By Leo Heuser

This procedure provides a workaround for the glaring lack of accessibility
in VBA for manipulating custom number formats. To do this, it hacks into
the Number Format dialog box with SendKeys. It loops through each item,
including those custom number formats that have been orphaned from the
worksheet. The dialog box flickers upon each opening, but it works! If
anyone comes up with a way to eliminate the flicker, let me know.

Sub DeleteUnusedCustomNumberFormats()
    Dim Buffer As Object
    Dim Sh As Object
    Dim SaveFormat As Variant
    Dim fFormat As Variant
    Dim nFormat() As Variant
    Dim xFormat As Long
    Dim Counter As Long
    Dim Counter1 As Long
    Dim Counter2 As Long
    Dim StartRow As Long
    Dim EndRow As Long
    Dim Dummy As Variant
    Dim pPresent As Boolean
    Dim NumberOfFormats As Long
    Dim Answer
    Dim c As Object

    NumberOfFormats = 1000
    ReDim nFormat(0 To NumberOfFormats)
    AnswerText = "Do you want to delete unused custom formats from the workbook?"
    AnswerText = AnswerText & Chr(10) & "To get a list of used and unused formats only, choose No."
    Answer = MsgBox(AnswerText, 259)
    If Answer = vbCancel Then GoTo Finito
