Delete worksheet if cells are empty - vba

Question

This would be a very simple question.
But I am not sure why this is not working in my excel vba code.
Sheets("I- ABC").Select
If IsEmpty(Range("A3").Value) = True And _
IsEmpty(Range("A4").Value) = True And _
IsEmpty(Range("A5").Value) = True And _
IsEmpty(Range("A6").Value) = True Then
Sheets("I- ABC").Delete
End If

Answer 1

What type of error do you get? I tried this code and Excel displays only warning message:
You can avoid this message by adding:
Application.DisplayAlerts = False
and
Application.DisplayAlerts = True
at the beginning and at the end of your code respectively.
--Edited code
Sub Example()
Application.DisplayAlerts = False
With Sheets("I- ABC")
If Application.WorksheetFunction.CountA(.Range("A3:A6")) = 0 Then
.Delete
End If
End With
Application.DisplayAlerts = True
End Sub

Answer 2

Try Similiar to This
Sub Test()
Application.DisplayAlerts = False
With Sheets("Sheet1")
Columns("A:A").SpecialCells(xlCellTypeBlanks).EntireRow.Delete
End With
Application.DisplayAlerts = True
End Sub
PS: It works for me and deletes rows containg empty cells in `A:A``
Approach Suggested by #Tim Williams also works for me as per following code in my situation
Sub Test6()
Dim r As Range, rows As Long, i As Long
Set r = ActiveSheet.Range("A3:A6")
rows = r.rows.Count
For i = rows To 1 Step (-1)
If WorksheetFunction.CountA(r.rows(i)) = 0 Then r.rows(i).Delete
Next
End Sub
It works even if we use Application instead of WorksheetFunction

Answer 3

If If Application.CountA(Range("A3:A6")) = 0 Then is not working as Tim suggested then that means the cells have blank spaces or unprintable characters.
Try this
Sub Sample()
Dim pos As Long
With Sheets("I- ABC")
pos = Len(Trim(.Range("A3").Value)) + _
Len(Trim(.Range("A4").Value)) + _
Len(Trim(.Range("A5").Value)) + _
Len(Trim(.Range("A6").Value))
If pos = 0 Then
Application.DisplayAlerts = False
.Delete
Application.DisplayAlerts = True
Else
MsgBox "The cells are not empty"
End If
End With
End Sub

Answer 4

With skkakkar's idea expanded.
Sub Hello()
Dim rng As Range
Application.DisplayAlerts = 0
On Error GoTo er
Set rng = Range("A3:A6").SpecialCells(xlCellTypeConstants, 23)
Exit Sub
er: MsgBox "ActiveSheet.Delete" 'delete sheet
End Sub

Answer 5

If the spaces are the issue, then you can try this code:
Public Sub RemoveIfEmpty()
Application.DisplayAlerts = False
With Sheets("I- ABC")
If Trim(.Range("A3") & .Range("A4") & .Range("A5") & .Range("A6")) = "" Then
.Delete
End If
End With
Application.DisplayAlerts = True
End Sub
