Target vba excel описание

Событие Worksheet.SelectionChange, используемое в VBA Excel для запуска процедур при выборе диапазона на рабочем листе, в том числе отдельной ячейки.

Синтаксис процедуры, выполнение которой инициируется событием Worksheet.SelectionChange:

Private Sub Worksheet_SelectionChange(ByVal Target As Range) ‘Операторы процедуры End Sub

Эта процедура VBA Excel запускается при смене на рабочем листе выделенного диапазона (SelectionChange). Она должна быть размещена в модуле рабочего листа Excel, смена выбранного диапазона ячеек которого будет инициировать ее запуск.

Аргумент Target — это новый выбранный диапазон на рабочем листе.

Шаблон процедуры можно скопировать и вставить в модуль рабочего листа, но не обязательно. Если открыть модуль нужного листа, выбрать в левом верхнем поле объект Worksheet, шаблон процедуры будет добавлен автоматически:

У объекта Worksheet есть и другие события, которые можно выбрать в правом верхнем поле модуля рабочего листа. Процедура с событием SelectionChange добавляется по умолчанию.

Примеры кода с Worksheet.SelectionChange

Пример разработчика

Замечательный пример дан на сайте разработчика:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)    With ActiveWindow       .ScrollRow = Target.Row       .ScrollColumn = Target.Column    End With End Sub

При выборе на листе любого диапазона, в том числе отдельной ячейки, лист автоматически прокручивается по горизонтали и вертикали, пока выделенный диапазон не окажется в верхнем левом углу экрана.

Эта процедура работает и при выборе ячейки через адресную строку (слева над обозначениями столбцов), и при выборе из кода VBA Excel, например:

Выбор одной отдельной ячейки

Инициируем выполнение основных операторов процедуры с событием Worksheet.SelectionChange выбором одной отдельной ячейки:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)     If Target.Address = «$E$5» Then         MsgBox «Выбрана ячейка E5»     End If End Sub

Основной оператор MsgBox "Выбрана ячейка E5" будет выполнен при выборе ячейки E5.

Примечание:
В условии примера используется свойство Address переменной Target, так как в прямом выражении Target = Range("E5") по умолчанию сравниваются значения диапазонов. В результате этого, при выборе другой ячейки со значением, совпадающим со значением ячейки E5, равенство будет истинным и основные операторы будут выполнены, а при выборе более одной ячейки, будет сгенерирована ошибка.

Выбор диапазона с заданной ячейкой

Выполнение основных операторов процедуры при вхождении заданной ячейки в выбранный диапазон:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)     If Not Intersect(Target, Range(«B3»)) Is Nothing Then         MsgBox «Ячейка B3 входит в выбранный диапазон»     End If End Sub

Основной оператор MsgBox "Ячейка B3 входит в выбранный диапазон" будет выполнен при выделении диапазона, в который входит ячейка B3, в том числе и при выделении одной этой ячейки.

Выбор ячейки в заданной строке

Инициируем выполнение основных операторов процедуры с событием Worksheet.SelectionChange выбором любой отдельной ячейки во второй строке:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)     If Target.Count > 1 Then Exit Sub         If Target.Row = 2 Then             MsgBox «Выбрана ячейка во второй строке»         End If End Sub

Дополнительный оператор If Target.Count > 1 Then Exit Sub необходим для выхода из процедуры при выделении более одной ячейки. Причина: при выделении произвольного диапазона, ограниченного сверху второй строкой, выражение Target.Row = 2 будет возвращать значение True, и операторы в блоке If ... End If будут выполнены.

Ввод даты в ячейку первого столбца

Автоматическое добавление текущей даты в выбранную ячейку первого столбца при условии, что предыдущая ячейка сверху не пустая, а ячейка снизу – пустая:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)     If Target.Count > 1 Or Target.Row = 1 Or Target.Row = ActiveSheet.Rows.Count Then Exit Sub         If Target.Column = 1 And Target.Offset(—1, 0) <> «» And Target.Offset(1, 0) = «» Then             Target = Format(Now, «DD.MM.YYYY»)         End If End Sub

Этот код VBA может быть полезен при ведении реестра, базы данных на листе Excel с записью текущей даты в первой колонке.

Условие If Target.Count > 1 Or Target.Row = 1 Or Target.Row = ActiveSheet.Rows.Count Then Exit Sub завершает процедуру при выборе более одной ячейки, при выборе ячейки A1 и при выборе последней ячейки первого столбца.

Выбор ячейки A1 приводит к ошибке при проверке условия Target.Offset(-1, 0) <> "", так как происходит выход за границы диапазона рабочего листа.

Ошибка выхода за пределы рабочего листа происходит и при проверке условия Target.Offset(1, 0) = "", если выбрать последнюю ячейку первой колонки.

Примечание:
Текущая дата будет введена в следующую пустую ячейку первого столбца при переходе к ней от заполненной в том числе нажатием клавиши «Enter».

Пример без отслеживания Target

Если необходимо, чтобы процедура запускалась при любой смене выделенного диапазона, аргумент Target можно не отслеживать:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)     If [B1] > 100 Then         [A1].Interior.Color = vbGreen     Else         [A1].Interior.Color = vbBlue     End If End Sub

После ввода значения в ячейку B1, можно нажать Enter или кликнуть по любой другой ячейке рабочего листа, и событие Worksheet.SelectionChange сработает.

You may want to run your macro/VBA snippet when a cell changes its value, when a double click happens, when a sheet is selected, etc. In all these cases we use Worksheet Event Handler.  The Event Handler helps us run VBA code whenever a certain event occurs.

In this article, we will learn briefly about each Worksheet Event Handler.

What is a Worksheets Event Handler?

A worksheet event handler is a subroutine that is local to a worksheet module.

Where to write Worksheet Event Handler Code?

The worksheet Events are written in sheets objects only. If you write a worksheet event in some module or class module, there will be no error but they will just won’t work.

To write in the sheet object. Double click on it or right-click and click on view code. The code writing area will be shown.

How to write code for a specific event on the worksheet?

Now when you are in the editing mode, in the top-left corner dropdown menu you will see general. Click on the drop-down and select worksheet. Now in the top-right corner dropdown, all events will show. Choose whichever you need and a skeletal code for that event will be written for you.

Each event has a fixed procedure name. These are the reserved subroutine names. You can’t use them for other subroutines on a sheet. In a module, they will work as a normal subroutine.

Important: Each subroutine from that list will run on the specified event.
One type of worksheet event procedure can be written only once on one sheet. If you write two same event handling procedures on one sheet, it will result in an error and none of them will be executed. Of course, the error will be ambiguous subroutines.

Let’s learn briefly about each of the events.

1. The Worksheet_Change (ByVal Target As Range) Event

This event triggers when we make any change to containing worksheets (formatting excluded). If you want to do something if any change made in the entire sheet then the code will be:

Private Sub Worksheet_Change(ByVal Target As Range)
  'do somehting 
  Msgbox "done something"
End Sub

The «Target» is the Active cell always.

Another example: You may want to put date and time in Cell B1 if A1 changes. In that case, we use the worksheet_change event. The code would look like this:

Private Sub Worksheet_Change(ByVal Target As Range)
 If Target.Address = "$A$1" Then
  Range("B1").Value2 = Format(Now(), "hh:mm:ss")
 End If
End Sub

This will target only the cell A1.

If you want to target a range then use the below example:

Run Macro If Any Change Made on Sheet in Specified Range

2. The Worksheet_SelectionChange(ByVal Target As Range) Event

As the name suggests, this event triggers when the selection changes. In other words, if your cursor is in Cell A1 and it moves to some other cell, the code in this subroutine will run.

The below code will change the active cells color if whenever it changes and if it is an even row.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
 If Target.Row Mod 2 = 0 Then
    Target.Interior.ColorIndex = 22
 End If
End Sub

Now, whenever my cursor will move on even row, it will be colored. Odd row cells will be spared.

3. The Worksheet_Activate() Event

This event is triggered when the event code containing sheet activates. The skeletal code for this event is:

Private Sub Worksheet_Activate()

End Sub

A simple example is showing the sheet name when it gets selected.

Private Sub Worksheet_Activate()

  MsgBox "You are on " & ActiveSheet.Name

End Sub

As soon as you will come on the sheet that contains this code, the event will run and will be shown a message that «You are on sheet name» (sheet2 is in my case).

4. The Worksheet_Deactivate() Event

This event triggers when leaving the code containing sheet. In other words, if you want to do something, like hiding rows or anything when you leave the sheet, use this VBA event. The syntax is:

Private Sub Worksheet_Deactivate()
'your code
'
End Sub

The below example Worksheet_Deativate event will simply pop up a message that you have left the master sheet, when you will leave this sheet.

Private Sub Worksheet_Deactivate()
  MsgBox "You Left The Master Sheet"
End Sub

5. The Worksheet_BeforeDelete() Event

This event triggers when you confirm the deletion of the VBA event containing sheet. The syntax is simple:

Private Sub Worksheet_BeforeDelete()

End Sub

The below code will ask you if you want to copy the content of the about-to-delete sheet.

Private Sub Worksheet_BeforeDelete()
    ans = MsgBox("Do you want to copy the content of this sheet to a new sheet?", vbYesNo)
    If ans = True Then
    'code to copy
 End If
End Sub

6. The Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean) Event

This event triggers when you double click on the targeted cell. The syntax of this VBA Worksheet Event is:

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)

End Sub

If you don’t set the target cell or range, it will fire on every double click on the sheet.
The Cancel variable is a boolean variable. If you set it True, the default action won’t happen. It means if you double click on the cell it won’t get into editing mode.
The below code will make the cell fill with a color if you double click on any cell.

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)

Cancel = True
Target.Interior.ColorIndex = 7

End Sub

The below code targets the cell A1. If it is already filled with the specified color then it will vanish the color. It is much like a like button or check box.

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
   If Target.Address = "$A$1" Then
   
   Cancel = True
    If Target.Interior.ColorIndex = 4 Then
        Target.Interior.ColorIndex = xlColorIndexNone
    Else
        Target.Interior.ColorIndex = 4
    End If
    
   End If
   
End Sub

7. The Worksheet_BeforeRightClick(ByVal Target As Range, Cancel As Boolean) Event

This event triggers when you Right-Click on the targeted cell. The syntax of this VBA Worksheet Event is:

Private Sub Worksheet_BeforeRightClick(ByVal Target As Range, Cancel As Boolean)
   Cancel = True
   '
   'your code
   '
End Sub

The below code will fill the cell with value 1 if you right-click on it. It won’t show the default right-click options since we have set the «Cancel» Operator to True.

Private Sub Worksheet_BeforeRightClick(ByVal Target As Range, Cancel As Boolean)
   Cancel = True
   Target.Value = 1
End Sub

8. The Worksheet_Calculate() Event

If you want something to happen when a excel calculates a sheet, use this event. It will trigger whenever excel calculates a sheet. The syntax is simple:

Private Sub Worksheet_Calculate()
  '
   'your code
   '  
End Sub

6. The Worksheet_FollowHyperlink(ByVal Target As Hyperlink) Event

This procedure will run when you click on a hyperlink on the sheet.  The basic syntax of this event handler is:

Private Sub Worksheet_FollowHyperlink(ByVal Target As Hyperlink)
    '
   'your code
   ' 

End Sub

You can set the target hyperlink if you want. If you don’t set the target hyperlink, it will get executed if you click on any hyperlink on the code containing sheet.

The worksheet event-handler procedures must be in the code module for that worksheet. Put them somewhere else, and they won’t work. You can quickly access that code window by right-clicking the worksheet’s tab and selecting the View Code:

Worksheet_Change event procedure

The Change event triggers whenever any cell in the worksheet is changed. Excel uses the Worksheet_Change event-handler procedure to trap the Change event. The Worksheet_Change procedure accepts Target (the Range object) as the parameter which represents the cell that was changed. The following example displays a message box that shows the address of the Target range:

Private Sub Worksheet_Change(ByVal Target As Range)
 MsgBox Target.Address
End Sub

Try making some changing in cells, every time you make changes, a message box displays the address of the cell that changed.

Monitor changes made to specific cell or range

The Worksheet_Chnage procedure receives the Target as Range object which represents the changed cell(s). In this example, we compare the Target with the given cell range A1:A10 using Intersect method:

Private Sub Worksheet_Change(ByVal Target As Range)
 Dim MyRange As Range
 Set MyRange = Range("A1:A10")
 If Not Intersect(Target, MyRange) Is Nothing Then
  MsgBox ("You've changed the " & Target.Address)
 End If
End Sub

A popup message box appears when a change made in the given cell range:

Worksheet_Change Vs. Worksheet_Calculate

The Worksheet_Change event procedure is not executed by a calculation change, for example, when a formula returning a different value. You must use the Worksheet_Calculate event procedure to capture the changes to values in cells that contain formulas.

Worksheet_SelectionChange event procedure

The Worksheet_SelectionChange event procedure executes when a cell is selected. The following code highlights the active cell with a red color every time a different cell is selected:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
 Cells.Interior.ColorIndex = 0
 Target.Interior.ColorIndex = 3
End Sub

The first statement removes the background color for all cells in the worksheet. Next, the the active cell is shaded with red color.

Take some action when specific cells or ranges selected

In many cases, you need to execute a piece of code when certain cells or ranges selected. To accomplish this, we use the Intersect method on the Target (selected cell or range) and the range containing the specific cell to verify the Target is one of the specific cells or ranges. If the Target is in the range containing the specific cells, you can execute the code.

The following code highlights the active cell with a red color every time a different cell is selected:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
 Cells.Interior.ColorIndex = 0
 Dim MyRange As Range
 Set MyRange = Range("A1:A10")
 If Not Intersect(Target, MyRange) Is Nothing Then
  Target.Interior.ColorIndex = 3
 End If
End Sub
