Find Last Cell, Column And Row in Excel Worksheet

Hi All,

Please find below a small code snippet, which you can use to find the last Used Cell, Row or Column.

Public Function LastUsedCell() As Range
    Dim rng As Range
    Dim activeSht As Worksheet
    On Error GoTo ErrHandler
    
    Set activeSht = activeSheet

    Set rng = activeSht.Range("A1").SpecialCells(xlCellTypeLastCell)
    
    'return value
    Set LastUsedCell = rng
    Exit Function
ErrHandler:
    Set LastUsedCell = Nothing
End Function

Public Function LastUsedRow() As Long
    Dim rng As Range
    Dim activeSht As Worksheet
    On Error GoTo ErrHandler
    
    Set activeSht = activeSheet

    Set rng = activeSht.Range("A1").SpecialCells(xlCellTypeLastCell)
    
    'return value
    LastUsedRow = rng.Row
    Exit Function
ErrHandler:
    LastUsedRow = 0

End Function


Public Function LastUsedColumn() As Integer
    Dim rng As Range
    Dim activeSht As Worksheet
    On Error GoTo ErrHandler
    
    Set activeSht = activeSheet

    Set rng = activeSht.Range("A1").SpecialCells(xlCellTypeLastCell)
    
    'return value
    LastUsedColumn = rng.Column
    Exit Function
ErrHandler:
    LastUsedColumn = 0

End Function

Hope this helps :)

Excel VBA : Loop through all the files and subfolders in a Folder

Hi All,

I write this function many many times in my projects. When we have to create a temporary folder which are specific to our application, then I normally have to loop through all the files in a folder and put some validations so that my code should not replace any previous temp or log files. So I thought to share a small snippet of Excel VBA code where I am trying to search all the files in a Folder ( and its subfolders too) and printing in an Excel Worksheet.

Private fileCounter As Integer
Private activeSht As Worksheet
'Display all the files in a folder. Searches all the sub folders.

'Prints Folder Names in Column A and and the file Names in Column B

Sub SearchFiles()
    Dim pth As String
    Dim fso As FileSystemObject
    Dim baseFolder As Folder
                    
    pth = "C:\Projects\" 'the base path which has to be searched for Files
    Set fso = New FileSystemObject
                    
    ''check if the folder actually exists or not
                    
    If (Not (fso.FolderExists(pth))) Then
        'the folder path is invalid. Exiting.
        MsgBox "Invalid Path"
        Exit Sub
    End If
    
    Set baseFolder = fso.GetFolder(pth)
    
    fileCounter = 1
    Set activeSht = ActiveSheet
    
    activeSht.Range("A1").Value = "Folder Name"
    activeSht.Range("B1").Value = "File Name"
    
    On Error GoTo ErrHandler
    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual
    PrintFileNames baseFolder
    
ErrHandler:
    Application.ScreenUpdating = True
    Application.Calculation = xlCalculationAutomatic
End Sub
    
    
Sub PrintFileNames(baseFolder As Folder)
    Dim folder_ As Folder
    Dim file_ As File
    
    For Each folder_ In baseFolder.SubFolders
        'call recursive function.
        PrintFileNames folder_
    Next folder_
    
    For Each file_ In baseFolder.Files
        'print files here
        activeSht.Range("A1").Offset(fileCounter, 0).Value = baseFolder.Path
        activeSht.Range("B1").Offset(fileCounter, 0).Value = file_.Name
        fileCounter = fileCounter + 1
    Next file_
End Sub
    

The above code loops through all the subfolders and the files in a given folder and prints the folder names in Column A and the file Names in Column B.

Write Custom Functions in Excel.

Hi,

We all know that we can write Formulas in Excel. for example, =Sum(A1:A10) to sum the values present in range from A1 to A10. The summation is easy. Right??? But what if we want to tweak our requirements.

Let's assume we have a requirement, that we need to sum only those values which are divisible by 2. I have assumed a very basic example, although we can write an Excel Built in for this requirement, but I want to show to achieve this through Custom Function.

For example, I want to sum range A1 to A10. I will write a custom Function in Excel VBA. Open VBA editor, add Module 1 and add a function like following :

Public Function SumEvenValues(rng As Range) As Double
    Dim sum As Double
    Dim cell_ As Range
    
    sum = 0
    
    For Each cell_ In rng.Cells
        If (IsNumeric(cell_.Value)) Then
            'the value is numeric. Check the mod
            If (cell_.Value Mod 2 = 0) Then
                sum = sum + cell_.Value
            End If
        End If
    Next cell_
    
    SumEvenValues = sum
    
End Function

In your excel workbook, in Cell b1, type this : =SumEvenValues(A1:A10)

You will see that all the values which are divisible by 2 are summed up and the result is displayed in Cell B1. I have taken a very basic example to show it's use, which can be easily achived in Excel, but we may encounter to include those requirements which we may not be able to achieve within Excel only. So in such a case, VBA is used to handle all those requirements which Excel cannot handle.

Linking Two Pivot Tables

Hi all,

Recently, I was making a dashboard and I had to create two Pivot Tables. My conditional formatting was set in such a manner, that I needed to have both the pivot tables updated @ same time, and the items too, to be shown or hid @ the same time in both the pivot table.

To achieve this, I first noted down the fields which I had to filter. I had three fields to filter and these items were Name, Date, and Month. So I had to make the following code :


Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
'ExpectedHours

If (Target.Name = "MainPivot") Then
      Macro1
End If

End Sub

Sub Macro1()
'

'
'On Error Resume Next
'
      Dim pivotSource As PivotTable
      Dim pivotTarget As PivotTable
      Dim sourceItem As PivotItem
      Dim sourceField As PivotField
      Dim targetItem As PivotItem
      Dim targetField As PivotField
      
      Set pivotSource = Sheet7.PivotTables("MainPivot")
      Set pivotTarget = Sheet7.PivotTables("ExpectedHours")
      
      
    Set targetField = pivotTarget.PivotFields("department")
   
    targetField.ClearAllFilters
    targetField.CurrentPage = Sheet7.Range("Department").Value
   
   
    Set sourceField = pivotSource.PivotFields("Name")
    Set targetField = pivotTarget.PivotFields("Name")
   
    For Each sourceItem In sourceField.PivotItems
            
            Set targetItem = GetPivotItemByName(targetField, sourceItem.Name)
            
            If (Not (targetItem Is Nothing)) Then
            
                  If (targetItem.Visible <> sourceItem.Visible) Then
                        targetItem.Visible = sourceItem.Visible
                  End If
            End If
    Next sourceItem
      
      
    Set sourceField = pivotSource.PivotFields("Date")
    Set targetField = pivotTarget.PivotFields("Date")
   
    For Each sourceItem In sourceField.PivotItems
            
            Set targetItem = GetPivotItemByName(targetField, sourceItem.Name)
            
            If (Not (targetItem Is Nothing)) Then
            
                  If (targetItem.Visible <> sourceItem.Visible) Then
                        targetItem.Visible = sourceItem.Visible
                  End If
            End If
    Next sourceItem
      
            
    Set sourceField = pivotSource.PivotFields("Month")
    Set targetField = pivotTarget.PivotFields("Month")
   
    For Each sourceItem In sourceField.PivotItems
            
            Set targetItem = GetPivotItemByName(targetField, sourceItem.Name)
            
            If (Not (targetItem Is Nothing)) Then
                  If (targetItem.Visible <> sourceItem.Visible) Then
                        targetItem.Visible = sourceItem.Visible
                  End If
                  
                  If (targetItem.ShowDetail <> sourceItem.ShowDetail) Then
                        targetItem.ShowDetail = sourceItem.ShowDetail
                  End If
            End If
    Next sourceItem
End Sub


Public Function GetPivotItemByName(field As PivotField, item As String) As PivotItem
      On Error Resume Next
      Dim pvItem As PivotItem
      
      Set pvItem = Nothing
      
      Set pvItem = field.PivotItems(item)
      
      Set GetPivotItemByName = pvItem
End Function

Hope this helps :)
