SummaryWelcome to Visual Basic 105 presented by vblearningzone.com. I am your instructor, Richard Rost. In this class, we are going to spend a significant amount of time focusing on various controls such as option buttons, control arrays, list boxes, multi-select list boxes, combo boxes, drop-down lists, scroll bars, and more, including the timer control. Not only will we cover how to use these controls, but we will also examine the different events that are associated with each one. Before you take this class, you should already have completed VB104. I also strongly suggest you take the earlier courses 101, 102, and 103 before proceeding with this one to ensure you have a solid foundation. There is a class website at vblearningzone.com. Visit the VB105 page to download sample project files, look at the course outline, and participate in the student discussion forum. If you have any questions about the material from this class, that discussion forum is the best place to ask. If you are viewing this class using the Amocrine Video Player or the Online Theater, you will see the class page displayed next to the videos. Feel free to join the discussion by posting your thoughts and questions. For this course, I will be working in Microsoft Visual Basic 6.0. If you are using a different version like VB.NET or VB2005, you might notice that the user interface is not the same, but most of the programming concepts and code that I teach here should still apply. My recommendation is to watch each video all the way through once before you try to follow along. Once you have watched the video, go back and work through the examples step-by-step to build each project as I do it. Please do not try to immediately use what you are learning here in other projects you may be working on. It is best to build the sample project alongside me in class, so you can really get the hang of the techniques. You can find a complete video tutorial with step-by-step instructions on everything discussed here on my website at the link below. Live long and prosper, my friends. Topic ListOption buttons and their properties Creating and managing control arrays Using list boxes in forms Implementing multi-select list boxes Working with combo boxes Creating drop-down lists Using scroll bars in forms Adding and configuring timer controls Examining control events and event handling ArticleWelcome to this guide on working with controls in Visual Basic. In this lesson, we will explore different types of controls such as option buttons, control arrays, list boxes, multi-select list boxes, combo boxes, drop-down lists, and scroll bars. We will also cover the timer control and learn about the events associated with each of these controls. Understanding how to use these controls and their events is essential for building engaging and interactive applications. To get the most from this tutorial, you should be familiar with the basics of Visual Basic, including how to create forms and place simple controls like text boxes and labels on them. If you need to review foundational concepts, spend some time going through introductory lessons before continuing. Let us start by discussing option buttons. An option button allows a user to select one choice from a group of options. For example, if you have a form where a user needs to select their gender, you might use two option buttons labeled Male and Female. Only one option can be selected at a time within the same group. In Visual Basic, you can group option buttons by placing them inside a frame or by managing their logic in code to ensure only one is selected. A control array is a collection of controls that share the same name and can be managed as a group, indexed by a number. For example, you might have several option buttons in a control array so that you can iterate through them using a loop in your code. This makes it easier to manage a group of controls that perform similar tasks. List boxes display a list of items from which a user can select. To add items to a list box in code, you use the AddItem method, like this: List1.AddItem "Apple" List1.AddItem "Banana" List1.AddItem "Orange" You can also make list boxes support multiple selections. To do this, set the MultiSelect property of the list box. With this configuration, users can select more than one item by holding down the Shift or Ctrl keys. To process the selections, you can use code like the following: Dim i As Integer For i = 0 To List1.ListCount - 1 If List1.Selected(i) Then MsgBox "You selected: " & List1.List(i) End If Next i Combo boxes are similar to list boxes but they offer a drop-down list combined with a text box so the user can either select an item from the list or type a new value. You can add items to a combo box with the AddItem method as well: Combo1.AddItem "Red" Combo1.AddItem "Green" Combo1.AddItem "Blue" When handling user choices in a combo box, use the Text property to read the selected or entered value. Drop-down lists are a style of combo box where the user must select from the list and cannot enter new values. This is controlled by setting the appropriate property in the combo box so it only accepts list values. Scroll bars allow users to select a value by dragging a slider. There are horizontal and vertical scroll bar controls. You set the Min and Max properties to define the range of the scroll bar. The Value property indicates the current value. For example, you might use a scroll bar to allow the user to select a number between 1 and 100. In the scroll bar's Change event, you can write code to update another control based on the new value: Private Sub HScroll1_Change() Text1.Text = HScroll1.Value End Sub The timer control lets you run code at regular intervals. For instance, you could update the time every second on your form. Set the Interval property, which is specified in milliseconds. For example, an interval of 1000 will fire the event once every second. To use the timer, enable it and write code in the Timer event: Private Sub Timer1_Timer() Label1.Caption = Time End Sub Each of these controls supports a range of events that you can use to respond to user actions. For example, the Click event of a button occurs when the user clicks the button, while the Change event of a text box occurs whenever its contents change. By writing code in these events, you can make your application interactive. When learning about these controls, it is best to start by adding them to your form and experimenting with their properties. Try adding code to their various events to see how the controls respond. For learning purposes, I recommend building the sample projects described here step by step. Do not immediately try to use these controls in your own complex projects. Instead, recreate the sample scenarios using simple forms to ensure you understand how each control and its events work. Once you are comfortable, you will be ready to apply these concepts to your own applications. If you have questions or need additional resources, there are many helpful websites and forums where you can find sample project files, course outlines, and discussion communities. Engaging in these discussions is a great way to deepen your understanding and get help from other learners and developers. By mastering option buttons, control arrays, list boxes, combo boxes, scroll bars, the timer control, and their events, you will be well equipped to build dynamic and user-friendly programs with Visual Basic. Practice building and experimenting with each control, and you will quickly become proficient in creating interactive applications.
