These pages collect example tutorials, programs and ActiveX controls
displaying particular programming techniques in Visual Basic. 

We cannot offer any further help with these examples. Most were
developed by students who are no longer present. Our current students have
moved onto programming in C#, and thus no longer use VB. Please do not
contact us for further help, although feel free to tell us that this page
was useful to you!

These tutorials contain step by step graphical guides to several visual basic
programming concepts and tools. Note that they are not necessarily in
progressive order!

Project  Description Authors 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

  • how to do simple object-based interactive graphics in VB
  • how to use a collection
  • how to use a class

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.

vbShapedControls

Illustrates
how you can clip the shape of a control or form to a variety of regions.

Shaun Kaasten

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
Rod Stephens

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

  • using the Extender object in a VB UserControl to access
    outside properties and methods
  • the use of calls from
    the Win32 API for finding mouse cursor coordinates
  • scaling those
    coordinates in terms of a container object (be it a form or another
    control container)

Michael Rounding

vbRangeSlider Illustrates a very crude range slider
written in ActiveX. I include it to

  • show you how you can do interactive graphics (well, at least some
    simple stuff), 
  • how you can make an active x control that you can include in a
    project. 

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

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.
