Updating Cells by Clicking Another Cell in Excel using VBA
In this article, we will discuss how to update cells by clicking another cell in Excel using VBA. This technique can be useful when you want to automate certain tasks in Excel or create dynamic user interfaces.
Prerequisites
Before we begin, it is assumed that you have a basic understanding of Excel and VBA programming. You should also have the Microsoft Excel Object Library added to your VBA project references.
The Problem: Updating Cells by Clicking Another Cell
The user wants to update the value in cell A54 when they click on cell A43. They have tried different bits of VBA code but have not been successful. The following code snippet shows an example of what they have tried:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Intersect(Target, Range("A43")) Is Nothing Then
Range("A54").Value = "New Value"
End If
End Sub
This code uses the Worksheet_SelectionChange event to detect when the user selects cell A43. When this happens, the code sets the value of cell A54 to "New Value". However, this code does not work as expected because the value of cell A54 is not updated until the user clicks somewhere else in the worksheet.
The Solution: Using the Worksheet_SelectionChange Event with a Timer
To update the value of cell A54 immediately when the user clicks on cell A43, we can use a timer to check if the user has selected cell A43. The following code shows how to do this:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Intersect(Target, Range("A43")) Is Nothing Then
Application.OnTime Now, "UpdateCell"
Else
On Error Resume Next
Application.OnTime EarliestTime:=Now, Procedure:="UpdateCell", Schedule:=False
On Error GoTo 0
End If
End Sub
Sub UpdateCell()
Range("A54").Value = "New Value"
End Sub
This code uses the Worksheet_SelectionChange event to detect when the user selects cell A43. When this happens, the code sets a timer to call the UpdateCell subroutine immediately. The UpdateCell subroutine sets the value of cell A54 to "New Value". When the user selects a different cell, the timer is cancelled using the Application.OnTime method.
Key Concepts
- Using the Worksheet_SelectionChange event to detect when the user selects a cell
- Using the Application.OnTime method to set a timer to call a subroutine
- Cancelling the timer using the Application.OnTime method with the Schedule parameter set to False
