Introduction Event programming is a very powerful tool that you can use within your VBA code to monitor user actions, take appropriate action when a user does something, or monitor the state of the application as it changes.If you are programming with your own custom classes, you can extend the functionality of these classes by defining and raising your own custom events, broadcasting the event message to any object that is listening for events from your class.
Screen Updating = False at the beginning of your code, then if any user runs the code, they will not know what is going on and think that the computer system is not responding.
You can ask the code to display a status message on the status bar so that the user is informed about the current status of the code.
To unzip, right-click and select whatever Windows suggests to unzip the archive. You can do it "automatically" by putting code in the worksheet's code sheet.
The Work Sheet_Change procedure is activated every time something is changed in the worksheet. The next two macros are examples of what I call "automatic code," because they execute automatically, if a certain condition is met.
Events and Event Procedures were introduced in Excel97. Events and event procedures are the same for versions 97 through 2007.
No significant changes have been made to the event model since its introduction in Excel97.
If you write a 0 (zero) all hidden rows will be visible again, and old values in column A are deleted.
In the last example you can type something in cell A1, and all rows (except row 1) that have the same value in column A will be hidden.
A few new events have been added, but the overall structure of the event system is unchanged.
