Excel VBA: How To Delete Entire Row Or Entire Column

On previous post, I've explained how to delete cells shift to left and up, now i will explain how to delete entire row or entire column:

To delete entire row:

Sub deleteShiftLeft()
    Thisworkbook.Activesheet.Range("B10").EntireRow.Delete
End Sub

To delete entire column:

Sub deleteShiftUp()
    Thisworkbook.Activesheet.Range("B10").EntireColumn.Delete
End Sub

That's all. Fin.

Excel VBA: How To Delete Cell Shift Up and Shift Left

    Thisworkbook.Activesheet.Range("B10").Delete Shift:=xlToLeft

Excel VBA: How to check whether a sheet exist or not

Sometimes we need to check whether a sheet exist or not to avoid run time error. Below is a simple function to do that task:

Function isSheetExist(ByVal workbookName As String, ByVal sheetName As String) As Boolean
Dim ws As Worksheet, ss
Dim vbR As Boolean
   
    vbR = False
   
    Set ss = Workbooks(workbookName).Worksheets
    For Each ws In ss
        If (ws.Name = sheetName) Then
            vbR = True
            Exit For
        End If
    Next ws
    isSheetExist = vbR
End Function

And this is an example to use that function: 

Sub FunctionTest()
 If isSheetExist(ThisWorkbook.Name, "Sheet1") = False Then
     MsgBox "Sheet is not exist."
 Else
     MsgBox "Sheet is exist."
 End If
End Sub

I hope this example help you.

Excel VBA: Connect to Microsoft Access Database (MDB) using ADODB

First, you have to enable Microsoft ActiveX Data Object Library. Follow this instruction:
1. Open Visual Basic for Application, click Tools, then click Add References

2. Search for   Microsoft ActiveX Data Object Library

This is an example code to connect to ADODB:

Private Sub CommandButton1_Click()
Dim adoConn As New ADODB.Connection
Dim adoRS As New ADODB.Recordset

    adoConn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=test.mdb; Persist Security Info=False"
    adoConn.Open

    adoRS.Open "SELECT COUNT([employee_id]) AS empID FROM [Table1]", adoConn, adOpenKeyset, adLockOptimistic
   
    ActiveSheet.Range("A1").Value = adoRS!empID   
    If adoRS.State = adStateOpen Then adoRS.Close
    If adoConn.State = adStateOpen Then adoConn.Close
   
End Sub

Excel VBA: Find And Replace String Using VBA Code

There are several ways to replace string using VBA code,  by looping each cell or by using VBA Replace function.

Let's say that we want to replace "Macrosoft Excel" with "Microsoft Excel" from A1 through A500.

This first example loops from A1 through A500 and replace "Macrosoft Excel" with "Microsoft Excel".

Sub Find_Replace1()
    Dim I As Integer
    Dim SFind As String
    Dim SReplace As String
    
    SFind = "Macrosoft Excel"
    SReplace = "Microsoft Excel"
    For I = 1 To 500
        If Cells(I, 1).Value = SFind Then
            Cells(I, 1).Value = SReplace
        End If
    Next I
End Sub

The following example is more efficient than previous example:

Sub Find_Replace2()
    Dim SFind As String
    Dim SReplace As String
    
    SFind = "Macrosoft Excel"
    SReplace = "Microsoft Excel"

    Range("A1:A500").Replace _
        What:=SFind, Replacement:=SReplace, _
    LookAt:=xlWhole, MatchCase:=False
End Sub

If you to make the search case sensitive you can change the MatchCase property to true. And also if you want to replace data that contain part of the searched data you can change the LookAt property to xlPart.
