Excel VBA - Basics videos | Excel VBA Part 18 - Creating Functions
Posted by Andrew Gould on 17 February 2014
A VBA function is a procedure that can return a value and this video teaches you how to create them. You'll learn how to declare a function and how to add parameters, including optional parameters and default values. You'll also see several ways to call the functions you've written, including from other VBA procedures and from an Excel worksheet. The video also talks about how to rewrite existing subroutines to replace repetitive code with functions.

There are no exercises for this video.
Making a video bigger
You can increase the size of your video to make it fill the screen like this:
Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.
When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.
Improving the quality of a video
To improve the quality of a video, first click on the Settings icon:
Make sure you're playing your video so that the icons shown appear, then click on this gear icon at the bottom right-hand corner.
Choose to change the video quality:
Click on Quality as shown to bring up the submenu.
The higher the number you choose, the better will be your video quality (but the slower the connection speed):
Don't choose the HD option unless you have a fast enough connection speed to support it!
Is your Wise Owl speaking too slowly (or too quickly)? You can also use the Settings menu above to change your playback speed.
Usually you create a function of a type, such as:
Public Function MyFunc (arg As String) As String
However, I have come across functions such as:
Public Function MyFunc (arg As Someclass) As Dictionary
How does one go about learning this?
The only difference with this sort of function is that it returns an object, rather than a string of text. To set the value for this function, you'd need to include at the end a line of code beginning:
SET MyFunc = ...
Note the SET keyword because you're setting an object variable. If this doesn't make sense, I'd go back to the VBA series of tutorials and work your way through them.
