On Error Resume Next
Dim lLastRow As Integer
lLastRow = Cells.Find(What:=”*”, after:=Range(“A1″), SearchOrder:=xlByRows, _
If lLastRow = 0 Then
lLastRow = 1
End If
lastUsedRow = lLastRow

End Function

Function lastUsedCol() As Long
On Error Resume Next
Dim lLastCol As Integer
lLastCol = Cells.Find(What:=”*”, after:=Range(“A1”), SearchOrder:=xlByColumns, _
If lLastCol = 0 Then
lLastCol = 1
End If
lastUsedCol = lLastCol

End Function

Prompt for a file name using VBA

Function prompt4FileName(Optional sFolder As String = vbNullString, Optional sDefaultName As String = "Untitled") As String

Looking for a row using Find method against the Selection object

Function myFindRowPos(sText As Variant, oSheet As Worksheet, _
  Optional SearchDirection As XlSearchDirection = xlNext, _
  Optional SearchOrder As XlSearchOrder = xlByRows, _
  Optional sFindRange As String = "A1:A10000", _
  Optional LookAt As XlLookAt = xlWhole) As Long

  Dim lResult As Long, oRg As Range

  On Error GoTo errLabel

 Set oRg = Selection.Find(What:=sText, after:=ActiveCell, LookIn:=xlValues, LookAt:= _ LookAt, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:= _ False)   If Not oRg Is Nothing Then
     lResult = oRg.Row
     lResult = -1 'not found
        End IferrExit:
    myFindRowPos = lResult
    Set oRg = Nothing
    Exit Function
    lResult = -1
    Resume errExit
End Function

Increase VBA performance

If your macro include code to make many change in sheets, document, jumping in/out of them then you need to consider to turn off screen update to turning performance of your code. Consider following snip-set example. Comment out the red line to see the effect

Sub myMacro ()

    On Error Goto errLabel
    Application.ScreenUpdating = False

    for i =1 to 1000 

        With Sheets("Sheets1")
        End With
        With Sheets("Sheets2")
        End With

    Application.ScreenUpdating = True
    Exit Sub

    MsgBox "System stop processing with error: " & Err.Description, vbOKOnly + vbCritical,"HotIce Soft"
    Resume exitLabel
    Resume Next
End Sub

Quickly goto a row in Excel with VBA

Sub scroll2aRow(Optional lRow As Long = 0)
    On Error Resume Next

    Application.Goto ActiveSheet.Range("A" & lRow), True

End Sub

Use an Open File dialog in VBA with both Mac and Windows

Function myGetOpenFileName(Optional sPath As String) As String

            sPath = "the path to documents folder"
            sPath = " alias """ & sPath & """"
        End If
        sMacScript = "set sFile to (choose file of type ({" & _

            "return sFile"
         Debug.Print sMacScript
        sFile = MacScript(sMacScript)

    Else 'windows

        sFile = Application.GetOpenFilename("CSV files,*.csv,Excel 2007 files,*.xlsx", 1, _
            "Select file to import from", "&Import", False)

    End If

    myGetOpenFileName = sFileEnd Function
