Courses - Microsoft Visual Basic 103 |
| Description: |
Using Microsoft Visual Basic |
| Running Time: |
72 minutes |
| Pre-Requisites: |
Visual Basic 102 strongly recommended
|
| Versions: |
We use Microsoft Visual
Basic 6.0, but lessons are valid for most earlier
versions of VB, including 4 and 5. If you have VB.NET or
VB 2005, the Visual Basic code we use is similar, but
the programming interface has changed. These VB courses
do NOT cover VBA (Visual Basic for Applications) which is
what you need for Microsoft Office programming. For VBA, see the
individual Office applications (Word,
Excel, Access, etc.) Click here for

Notice: this course covers
the older Visual Basic 6.0 programming application. Microsoft no
longer sells VB6. If you want to learn VB6, you'll have to find a used
copy somewhere like eBay or Craigslist. We will be updating this course
for use with Visual Basic 2013 soon. If you've purchased this
course within the last year, you'll get a free upgrade when it's
released.
This course picks up where VB102
left off. We will begin by talking about Events and Properties,
such as GotFocus, LostFocus, ForeColor, BackColor, and FontBold. We'll
look at the Object Browser, color constants (such as vbRed, vbBlue,
etc.) and how to get any color into your objects.
In this example, the Last Name field
changes
color using the GotFocus event as the user
tabs to it, or clicks on it.
Next we'll learn about the different variable
types, such as Date, Integer, Single, and so on. We'll learn about
valid variable names and naming conventions. We'll learn how to Dim
variables, and the difference between public and private
variables. We'll learn how to find the length of a string with the
Len function. And, we'll learn about the Option Explicit
keyword and what it does.
In this example, we add up the
length of the
First Name and Last Name boxes with LEN function
Next we'll learn about a powerful programming
technique called the Select Case statement which can be used to
eliminate huge blocks of If/Then code.
We'll use the Select Case to create a Student
Test Score application where we'll figure a student's average and
letter grade based on his test scores.
Next we'll learn about the Form Load event,
the Form Resize Event, and see how different properties such as
the Caption, Width, and Height of a form can be changed at
runtime. We'll make a button so the user can resize a form.
In this example, when the user
clicks the resize button
the form opens up. Notice the pink label also resizes!
Next we'll learn about the Border Style and
Startup Position properties. This will allow us to change the way
our forms look on the screen, and where they first pop up when the
program loads. I'll show you how to manually place your form on the
screen where you want it to start.
The Form Layout Window allows you to
manually
position your forms anywhere on the screen.
