vbHelloWorld | A simple hello world program that illustrates a basic VB program as well as the command button and timer control. | Saul Greenberg |
FirstProject | We use this nonsense program as a first VB exercise for students to do. The left figure shows when it looks like when the program is executed, while the right shows what happens after the user has clicked the button 3 times and selected the checkbox, and moved the mouse over the form. Try to program this yourself. It uses a command (or button), a label, and a checkbox. | James Tam |
vbImages | These two vb Projects illustrates two ways to cycle through images stored in a local directory. Each demonstrates different controls for accessing files, while both show a control for displaying images. | Saul Greenberg |
vbMarquee | A marquee (an automatically scrolling text region) is used to illustrate a Timer, a status bar and a checkbox control, and simple graphical repositioning, | Saul Greenberg |
vbMoveList | An example of how to use listboxes (as well as how to put images into buttons). This example lets you move items between lists. | Rod Stephens, modified by Saul Greenberg |
vbPlaysound | Illustrates how to play a wave file in Visual Basic. It works by declaring a function to the WIN32 API sndPlaySound . Don't be intimidated: its two lines of code! | Saul Greenberg |
vbSketchpads | Illustrates two simple sketchpads. The first one is only about 6 lines of code, and just illustrates some very basic graphics and event handling. The second shows how one can dynamically create controls at run time (the items on the palette), how controls can be positioned at runtime, and how controls can be resized when the window is resized. Its a longer program, but well worth going through to see how these features work. See Tutorial 2 for step by step instructions for how these programs work. | Saul Greenberg |
vbDrawpad | A simple object-oriented drawing editor that allows a user to create, move and erase squares. You can easily extend this to include different graphical classes e.g., circles, lines, etc., or to any interactive graphics. The program illustrates
| Saul Greenberg |
vbDynamicQueries | This program is similar to the drawing editor above, but used for completely different purposes. It illustrates how to do dynamic queries on city attributes, where cities on a map are filtered immediately as a person moves a slider or checks a checkbox. While the example is simple, the possibilities of how you can enhance it are endless. Click on the image to view it in full size. | Saul Greenberg |
vbTableLens | Illustrates how to create a very simple table lens that toggles cells between graphical and textual views. Click on the image to view it in full size. | Rod Stephens |
vbDragPicture | Illustrates how to Bitblit a picture on another picture, and how to drag it around. | Rod Stephens |
vbDragTreeNode | Illustrates how to use the Tree control and how to drag items around different parts of the tree | Rod Stephens |
vbMoveControls | An example application that lets a user interactively move different kinds of controls on a display. Illustrates interactive graphics. | Saul Greenberg |
vbclassexample | Illustrates how to create a simple class that raises events | Saul Greenberg |
vbFlexdata-example | Illustrates a database with the flex control. The database just has two fields: name and phone. This example lets you add and remove records. To make the grid sorted, we set the data control's record source property to the SQL statment: Select * from friends order by FirstName. The record is just added to the end of the file, but the flex grid shows it sorted. See also Tutorial 3 and Tutorial 4 for other ways to access databases. | Shaun Kaasten |
vbShapedControls | Illustrates how you can clip the shape of a control or form to a variety of regions. | Shaun Kaasten |
ActiveX Controls
Project | Description | Author |
HelloWorld | A tutorial and example project that shows you how to build a minimalist VB ActiveX Control Component. It just contains a label saying "Hello World" and has no code attached to it. However, it does have a toolbox control icon. Includes an example program. | Saul Greenberg |
TickerTape | A tutorial and example project that shows you how to build a TickerTape control out of a label. It also illustrates the ActiveX Control Wizard. | Mike Rounding |
ElusiveProfessor | A VB ActiveX Control that creates a 'new' type of button (actually a standard but augmented command button) that moves away from the person who is trying to click it. Includes an example program. The design was based upon a class project where students had to design a button that reflected their personality. | Saul Greenberg |
FollowMe | This program creates a command button that will follow the mouse around. This simple but very useful example illustrates
| Michael Rounding |
vbRangeSlider | Illustrates a very crude range slider written in ActiveX. I include it to
It is limited. It does not scale its size, and I did not spend any time doing all the things that one normally does to package up a control. This is really just a quick hack. Feel free to improve it and pass it on to the class. To use: Unzip the file into a directory. Check out the test program in a sub directory that I included. In your own project, you can include the range slider by going into project/components and then selecting Browse. Navigate to the OCX file that will be in the unzipped directory and select it. You will see a new control that you can select. | Saul Greenberg |
PictureClip | A tutorial program that shows you how to use the PictureClip component for creating animations. | Dave Miller, 581 student |
ShowNeighbours | An activeX control plus exe that shows you how to find the other controls in a form from inside an ActiveX control. Saul Greenberg used this example to build a Mr. Popularity button, where all the other controls on the form gravitate towards a Mr Popularity ActiveX button. | Chris Bradley, 581 student |
xparent.zip | Illustrates how you can build a transparent ActiveX Control that lets you detect clicks on a non-rectangular image (in the figure on the right these would be the red letters). See Tutorial 8. | Mike Rounding, |
tranparent.zip | Similar to xparent.zip, except this version follows your mouse wherever it goes around the screen - very fun. | Mike Rounding, |
MovingControl.zip | This example includes a user control that will move itself towards any other control. This example illustrates some custom events and properties in a user control, and shows how to do do simple control animation with a timer. | Mike Rounding |
Third Party Examples
We've found these on the web or in books, and they are too good not to include
Project (as zip or .bas) | Description | Author |
animation | Bitmap Animation: Shows how to build a simple bitmap animation. | Rod Stephens |
Transparent.zip | Transparency: A tool library to do transparency, including transparent controls. | Doug Gaede |
vbRangeTool.zip | An ActiveX control that implements a range slider. Looks pretty good! | Author unknown |
VB-ScreenCapture.BAS | Capturing bitmaps: A BAS library for capturing various portions of a screen. |
