Excel VBA: How To Delete Entire Row Or Entire Column

2015-11-07T19:17:00.001+07:00

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

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

2015-11-07T17:53:00.000+07:00

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

2015-11-07T11:39:00.003+07:00

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

2009-12-27T10:16:00.000+07:00

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.

DateAdd(interval, number, date)

The DateAdd function syntax has these named arguments:

Part	Description
*interval*	Required. String expression that is the interval of time you want to add.
*number*	Required. Numeric expression that is the number of intervals you want to add. It can be positive (to get dates in the future) or negative (to get dates in the past).
*date*	Required. Variant (Date) or literal representing date to which the interval is added.

Settings

The interval argument has these settings:

Setting	Description
yyyy	Year
q	Quarter
m	Month
y	Day of year
d	Day
w	Weekday
ww	Week
h	Hour
n	Minute
s	Second

Excel VBA: Determining whether a path exists

2009-03-18T08:41:00.005+07:00

To check whether a path exists or not, we can use Excel VBA's GetAttr function. The following function returns True if a specified path exists, and return False otherwise:

Function isPathExist(ByVal pathname As String) As Boolean
 On Error Resume Next
 isPathExist = GetAttr(pathname) And vbDirectory = vbDirectory
End Function

Excel VBA: Determining Whether A File Exists Or Not

2009-03-10T11:55:00.024+07:00

There are several ways to check whether a file exists. By using Microsoft Excel VBA statements and functions, or by using FileSystemObject (Microsoft Scripting Library). The following function returns True if a particular file exist, and return False if file does'nt exist. This function uses Dir function to check whether a file exists or not.

Function isFileExist(ByVal fname As String) As Boolean
 isFileExist = False
 If Dir(fname) <> "" Then isFileExist = True
End Function

Here's example how to use the function above:

Sub FunctionTest()
 If isFileExist("D:\SomeFile.txt") = False Then
     MsgBox "File not exists."
 Else
     MsgBox "File already exist."
 End If
End Sub

The next function do exactly as previous function, but this function uses FileSystemObject to check whether a file exist:

Function isFileExist2(ByVal fname As String) As Boolean
    Set fs = CreateObject("Scripting.FileSystemObject")
    
    isFileExist2 = fs.FileExists(fname)
End Function

FIN.

Excel VBA: Cell Alignment

2009-03-05T12:59:00.009+07:00

In Excel VBA macro we can control the alignment of cell, both horizontally and vertically. To change alignment, we can use the following properties of the Range object:

HorizontalAlignment. Set to xlLeft, xlCenter, xlRight, xlDistributed, or xlJustify.
VerticalAlignment. Set to xlTop, xlCenter, xlBottom, xlDistributed, or xlJustify.

Following example sets horizontal alignment to justify:

Worksheets("Sheet1").Range("A1:D5").HorizontalAlignment = xlJustify

Excel VBA: Font Formatting

2009-03-03T17:53:00.018+07:00

When we working in Excel, if we want to changes font properties we may use Font tab in the Format Cells dialog box. In Excel VBA, we control the font's appearance by the Font object. The Font object have several properties that correspond to various aspects of the font's appearance. Here are several list of font's properties:

Property	Description
Name	The name of the font.
Bold	True if the font is bold. Read/write Variant.
Italic	True if the font style is italic. Read/write Boolean.
Underline	Returns or sets the type of underline applied to the font. Can be set to xlUnderlineStyleNone, xlUnderlineStyleSingle, xlUnderlineStyleDouble, xlUnderlineStyleSingleAccounting, xlUnderlineStyleDoubleAccounting. Read/write Variant.
Size	Returns or sets the size of the font. Read/write Variant.
Subscript	True if the font is formatted as subscript. False by default. Read/write Variant.
Superscript	True if the font is formatted as superscript; False by default. Read/write Variant.
Strikethrough	True if the font is struck through with a horizontal line. Read/write Boolean.

This example sets font name of range A1:B4 to Tahoma in ActiveSheet in ActiveWorkbook:

ActiveWorkbook.ActiveSheet.Range("A1:B4").Font.Name = "Tahoma"

The Color property uses an RGB value, which identifies a color in terms of its red, green,
and blue components. To set this property, use the RGB function:

RGB(r, g, b)

The next example sets font color of range B4 to Blue in ActiveSheet in ActiveWorkbook:

ActiveWorkbook.ActiveSheet.Range("A1:B4").Font.Color = RGB(0, 0, 255)

We can also use predefined constants to sets font color, they are vbBlack, vbRed, vbGreen, vbYellow, vbBlue, vbMagenta, vbCyan, and vbWhite.

This example do exactly as previous example:


ActiveWorkbook.ActiveSheet.Range("A1:B4").Font.Color = vbBlue

Excel VBA: Changing Row and Column Size

2009-03-02T14:06:00.007+07:00

Sometimes, in Microsoft Excel we need to change width of columns or height of rows in a worksheet to accomodate data they contain. In Excel Visual Basic for Application (VBA macro), to change columns width we can use ColumnWidth property. Following excel macro code sets width of column C in "Sheet1" worksheet to 24:

Sheets("Sheet1").Columns("C").ColumnWidth = 24

To change columns width to fit data in columns, we can use AutoFit method. The following example uses AutoFit method to change the size of C:F in the "Sheet1" worksheet:

Sheets("Sheet1").Columns("C:F").AutoFit

RowHeight property is used to change rows height of a range. For example:

Sheets("Sheet1").Rows(2).RowHeight = 56

Excel VBA: Number Formatting in Excel VBA Macro

2009-03-01T07:34:00.007+07:00

Number formatting controls how numbers on cells are displayed, it has no effect on cells that contain text. In Microsoft Excel, if we want to apply number formatting we can use Format Cells dialog box. To format numbers in VBA macro we can use the NumberFormat property. Following are some number formatting codes to format numbers.

Number Formatting Codes

Character	Meaning	Code example	Format example
#	Significant digit	##.#	10.78 displays as 10.9
0	Nonsignificant 0	#.00	5.4 displays as 5.40
.	Decimal point	##.##	14.55 displays as 14.55
$	Currency symbol	$#.##	56.78 displays as $56.78
%	Percent symbol	#.#%	0.075 displays as 7.5%
,	Thousands separator	#,###	123000 displays as 123,000

Here is the example VBA code to display numbers with no commas or special characters, and no decimal places:

Sub NumFormat()
 Range("A1").NumberFormat = "0"
End Sub

We can display positive and negative numbers differently. Following number format code will display negative numbers in red color.

#.##;[Red]#.##

To specify a display color, include the color name enclosed in square brackets at the start the format code. The available color names are:

Black
Blue
Cyan
Green
Magenta
Red
White
Yellow

Excel VBA: How To Delete Cells That Contain Certain Word

2009-02-16T19:57:00.016+07:00

Sometimes, when we working with excel we need to delete cells that contain certain word. In this section, we will create excel vba macro code to delete cells that contain certain word.

Firstly, we have to create a function that we need for our next procedure. This function will count number of certain word in active sheet.

Function countText(ByVal searchText As String)
Dim rS As Range, counter As Long

counter = 0
Set rS = Cells.Find(searchText, LookIn:=xlValues, LookAt:=xlWhole)

If Not rS Is Nothing Then
    fAddress = rS.Address
    Do
        counter = counter + 1
        Set rS = Cells.FindNext(rS)
    Loop While Not rS Is Nothing And rS.Address <> fAddress
End If

countText = counter
End Function

And then, here is the main part of the procedure that will delete cells that contain certain word.

Sub DeleteCells(ByVal sText As String)
Dim r As Range

While countText(sText) > 0
    Set r = Cells.Find(sText, LookIn:=xlValues, LookAt:=xlWhole)

    If Not r Is Nothing Then
        r.Delete
    End If
Wend
End Sub

Here is an example how to use the procedure above. This example will delete cells that contain word "blablabla" in active sheet.

Sub TheExample()
DeleteCells ("blablabla")
End Sub

Excel VBA: Find A Particular Text Within Ranges And Return Its Row Position

2009-02-15T07:02:00.012+07:00

In Microsoft Excel, sometimes we need to find the row position of particular text or even formula, to be able to insert certain of data below the corresponding text or even to delete row that contain the corresponding text.
This is an excel vba macro code to return row position that contain specific text.


Function rowPosition(ByVal searchText As Variant, _
    Optional ByVal stLookAt As XlLookAt = xlPart) As Long
    
    Dim rPos As Long, rS As Range
    
    rPos = 0
    
    Set rS = Cells.Find(searchText, LookIn:=xlValues, LookAt:=stLookAt)
    
    If Not rS Is Nothing Then rPos = rS.Row
    
    rowPosition = rPos
    
End Function

The function above have two arguments:

searchText : the text you are searching for
stLookAt : use xlWhole if you want to search the whole text, or use xlPart if otherwise

Here is example how to use the function above. This example deletes entire row that contain word "Test".

Sub RunExample()
    Dim rwPos As Long
       
    'Find row position
    rwPos = rowPosition("Test", xlPart)
    
    'If found then delete entire row
    If rwPos > 0 Then Rows(rwPos).Delete
End Sub

Excel VBA: Check Whether Workbook Is Already Open Or Not

2009-02-14T21:10:00.007+07:00

I often transfer data from current excel workbook to another excel workbook repeatedly. And I prefer creating vba macro to automate the task rather than doing it manually, which is very time consuming. So, before I open the destination excel workbook, I need to check whether the destination excel workbook is already open or not.

The following vba macro code is the function to check whether a workbook is already open or not. This function is quiet simple, it just do looping in Workbooks collection to check all opened workbook, if there is a workbook that have same name with the workbook we are looking for, then the function will return True or False if otherwise.

Function isWorkbookOpen(bookName As String) As Boolean
Dim vbResult As Boolean
Dim wbs As Workbook

vbResult = False
For Each wbs In Workbooks
    If UCase(wbs.Name) = UCase(bookName) Then
        vbResult = True
        Exit For
    End If
Next wbs
isWorkbookOpen = vbResult
End Function

This example show you how to use the function above.

Sub openWorkbook()
If isWorkbookOpen("macroexcel.xls") = False Then
   Workbooks.Open "d:\macroexcel.xls"
Else
   MsgBox "Workbook macroexcel.xls is already open."
End If
End Sub

Excel VBA: Protect & Unprotect Worksheet/Excel File

2009-02-14T13:46:00.020+07:00

Imagine this; you are working with protected excel file, so only authorized user can access the file. Let's say you are the authorized user, and you are going to create macro excel that need an access to the protected file.

This vba macro example, sets password to excel file named "excel.xls". This example assumes excel file named "excel.xls" already open.

Sub ProtectExcel()
'write password
Workbooks("excel.xls").Password = "macroexcel"

'save workbook
Workbooks("excel.xls").Save
End Sub

This example opens the protected excel file named "excel.xls" on the D:\ drive.

Sub OpenProtectedExcel()
'open protected excel file
Workbooks.Open Filename:="D:\excel.xls", _
  Password:="macroexcel"
End Sub

This example remove protection from worksheet named "Sheet1" and protect it with new password.

Sub xProtect()
'Assumes excel.xls already open
'unprotect sheet
Workbooks("excel.xls").Sheets("Sheet1").Unprotect "password"

'protect sheet with new password
Workbooks("excel.xls").Sheets("Sheet1").Protect "vbamacro"

'save changes
Workbooks("excel.xls").Save
End Sub
