Hi all,
There are times when excel users need to detect when a cell is being mouse-clicked ... The worksheet Selection_Change event is often used for this purpose but it has two main problems :
A- it doesn't differenciate between keyboard and mouse selections
B- It doesn't work if the same cell is repeatedly clicked without first having activated another cell
The following small Class (C_CellClickEvent) uses the CommandBars _OnUpdate event in combination with a few API calls to overcome the issues mentioned above ... Once the Class is instantiated, the custom and easy-to-use Wb_CellClick(ByVal Target As Range) event handler located in the workbook module becomes available
Workbook Download demo
1- Here is the Class code : (Class name = C_CellClickEvent)
2- And here is an example of how to implement the Class : ( Code to be placed in the ThisWorkbook module)
Code Written and tested in Excel 2010 Win 10 (64bit)
