Count Function in Visual Basic (VBA)
Lecture description
Learn to use the Count function using Excel VBA and CommandButtons! We'll use a small data set to count how many cells are numeric using Application.WorksheetFunction.Count, or total number of cells that are not blank using CountA function. The cool thing about this approach is there's no formula to be overwritten or updated, just a static number thanks to Visual Basic in Excel!

Now we're going to show you the Count() function which is basically going to count everything in column C. Again we could use a more dynamic range if we felt like it. So we're going to do the same thing, we're going to go into design mode. And in fact I'm going to go into this and I'm just going to copy what we've already done because you guessed it, the count function is going to be really similar. Now if you don't know what the Count() function is - the SUM function is taking all these numbers and adding them together 20, 45, 300, 40 - that's going to equal 405, but the Count function will actually just give you the number of cells. So one two three four. So let's try this and then we may have to tweak it because look there's actually another cell to be counted. If we're taking C:C (the entire column). So let's take a look and we'll start our adventure here we go. I'm going to paste. So we want.. not F2 but F3. So let's tweak that a little bit. F3 is going to be equal to the Application.WorksheetFunction And in this case we're going to say .Count So let's see if there is a .Count Ah yes there is so dot count range. C:C - let's see what that does. Let's go ahead and click it and see what our result is at first. So we're going to get 4. OK. Now let's see what happens if we change it to CountA() . So there's a CountA() function in Excel as well. And that would give us 5. So the Count() function is actually just counting. Anything that's a number and the CountA() is counting anything that's not blank in this instance. So I would probably want to change this back to Count() and not CountA() But there's different uses for both functions. So play around with that and make sure you get which everyone tests well for what you're looking for . So the cool thing about this is once again click a couple of buttons or run your procedure and everything is there. And if it's erased it doesn't matter because you can run your procedure again. That's the Count() Function!
