By VBA for Excel 2016 is fast, but it’s not always fast enough. (Computer programs are never fast enough.) Keep reading to discover some programming examples you can use to speed up your macros. Turning off screen updating When executing a macro, you can sit back and watch all the onscreen action that occurs in the macro. Although doing this can be instructive, after you get the macro working properly, it’s often annoying and can slow the performance of your macro considerably. Fortunately, you can disable the screen updating that normally occurs when you execute a macro. You can instruct Excel to not display these types of alerts while running a macro. The secret trick to avoiding these alert messages is inserting the following VBA statement into your macro: Application.DisplayAlerts = False Excel executes the default operation for these types of messages. In the case of deleting a sheet, the default operation is Delete. If you’re not sure what the default operation is, perform a test to see what happens. When the procedure ends, Excel automatically resets the DisplayAlerts property to True. If you need to turn the alerts back on before the procedure ends, use this statement. Application.DisplayAlerts = True Simplifying object references As you probably already know, references to objects can become very lengthy. For example, a fully qualified reference to a Range object may look like this: Workbooks(“MyBook.xlsx”).Worksheets(“Sheet1”) _.Range(“InterestRate”) If your macro frequently uses this range, you may want to create an object variable by using the Set command. For example, the following statement assigns this Range object to an object variable named Rate: Set Rate = Workbooks(“MyBook.xlsx”) _.Worksheets(“Sheet1”).Range(“InterestRate”) After defining this object variable, you can use the variable Rate rather than the lengthy reference. For example, you can change the value of the cell named InterestRate: Rate.Value =.085 This is much easier to type than the following statement: Workbooks(“MyBook.xlsx”).Worksheets(“Sheet1”). _ Range(“InterestRate”) =.085 In addition to simplifying your coding, using object variables speeds your macros considerably. Declaring variable types You usually don’t have to worry about the type of data you assign to a variable.
