XOJO ARRAY NUMBER OF VALUES CODE
Remember - Live code will index from 1 rather than 0! occurrence = 0 desired_value = inputbox(“Please enter the age that you would like to keep count of”, “Enter Age”) For counter = 0 To 9 If age(counter) = desired_value Then occurrence = occurrence + 1 End If Next ("There were " & occurrence & “occurrences of ” & desired_value) It is possible to use a different object for output. In this example it is presumed that the array has already been populated.Ī list box is used to output the number of occurrences found. Once you get the hang of this, you’ll find that your programs will have more and more structures (arrays, dictionaries, etc) containing objects of your own design and fewer structures of less-meaningful intrinsic types, which makes your programs more concise, more readable and more powerful.Examples of count occurrences Visual Studio 2010 (Similar to VB5, VB6 and Subsequent Visual Basic.NET languages) When you need to store a bunch of cars, you’ll make an array of cars, instead of a bunch of arrays storing car properties. Or you can add methods to the Car class that allow it to do things to itself, so you have the more self-contained M圜ar.Recharge instead of Recharge(M圜ar). Now if you have a method that does something with a car, you can just pass a car object as a parameter to that method instead of having to pass all the properties of the car separately. so you can make a new car object using New and some parameters. Add a constructor method with parameters like color, make, model, etc. Now give it some properties, like color, make, model, number of doors, horespower, whatever. You don’t set its super to anything, it’s just an abstract object. For example, if you’re writing an app to do with cars, just make a Car class. But in fact, classes are something you can (and should) just toss together all the time as part of your everyday programming, as a way to encapsulate related properties and methods. That can be the case if you’re making, say a new control that might be useful to others. The thing I had to get over was the mindset that creating a class was a Serious Endeavor, and that The Class had to be finely crafted and passed down to generations of future programmers.
XOJO ARRAY NUMBER OF VALUES HOW TO
I have not created a class before and am unfamiliar with how to go about it Or add up the values of some numbers, or… Once you have a class you can add methods to it…for example you could add a method that sets all the strings to say “custard” (It may instead have named strings like my car, if that array actually contained things like an address) You Class will have an array of strings as a property. Instead you must do this: Dim M圜ar as new objCarĬarDictionary.value ("CarRegistration1") = SomeCarĬarDictionary.value ("CarRegistration2") = SomeCar Because unlike an integer or double, Xojo hasnt made a memory allocation for it yet. (you already know that for your original purpose this would be something(24) as string, right?) So right click on the class and ‘Add to objCar’ … Property Now, like a window, we can add properties
In the properties, rename Class1 as objCar If you need to deal with 10 cars, you might have thought:Īnd to set up the first car CarMake(0) = "Ford"īut better to group the variables together in a class.
You right click on it and can add properties, methods, and functions In a way, you can think of every window you add as a class.
