A better way to write to a range:Filling a range
Sub LoopFillRange()
Dim CurrRow As Long, CurrCol As Integer
Dim CurrVal As Long
CellsDown = 3
CellsAcross = 4

CurrVal = 1
Application.ScreenUpdating = False
For CurrRow = 1 To CellsDown

Next CurrCol

" Display elapsed time

Get the last cell

Is a cell empty
Sub ShadeEverySecondRow()
Dim i As Integer
i = 2
Do Until IsEmpty(Cells(i, 1))
Cells(i, 1).EntireRow.Interior.ColorIndex = 15

Magic Squares

Moving the pointer to the cell containing the greatest value
Sub GoToMax()
Dim WorkRange As range

Nest If statement in Do Loop Until for cells

Dim I As Integer

Transposing is taking a rectangular block of data and rotating it so that columns become rows and vice versa.
Public Sub Transpose()
Dim I As Integer
Dim J As Integer
Dim transArray() As Variant
Dim numRows As Integer
Dim numColumns As Integer
Dim colIndex As Integer
Dim rowIndex As Integer
Dim inputRange As Range

colIndex = inputRange.Column
rowIndex = inputRange.Row
numRows = inputRange.Rows.Count
numColumns = inputRange.Columns.Count
ReDim transArray(numRows - 1, numColumns - 1)
For I = colIndex To numColumns + colIndex - 1
For J = rowIndex To numRows + rowIndex - 1
transArray(J - rowIndex, I - colIndex) = Cells(J, I).Value
Next J
Next I
inputRange.ClearContents
For I = colIndex To numRows + colIndex - 1
For J = rowIndex To numColumns + rowIndex - 1
Cells(J, I).Value = transArray(I - colIndex, J - rowIndex)
Next J

End Sub
Use arrays to fill ranges faster
Sub ArrayFillRange()
Dim TempArray() As Integer
Dim TheRange As range
CellsDown = 3

StartTime = timer
ReDim TempArray(1 To CellsDown, 1 To CellsAcross)

CurrVal = CurrVal + 1
Next J
Next I
TheRange.value = TempArray
Application.ScreenUpdating = True
MsgBox Format(timer - StartTime, "00.00") & " seconds"
End Sub
Uses nested For/Next loops to count the total number of cells used in all open worksheets:
Public Sub numCells()
Dim I As Integer
Dim K As Integer
Dim numCells As Long
For K = 1 To Workbooks.Count "Loop through workbooks
Workbooks(K).Activate
For I = 1 To Worksheets.Count "Loop through worksheets
numCells = numCells + Worksheets(I).UsedRange.Count
Next I
Next K
MsgBox (numCells)
End Sub
