Visual Basic Concepts

• VB is a Visual programming language
• 3 steps in constructing a program
• Build the User Interface
• Customize the properties of the interface
• Attach Program Code
• VB is Event Driven.
• VB is also an Object-Oriented programming
  language.

VB Project Contents

• Form Files (.frm)
• contain all interface controls and associated VB
  code
• Module Files ( .bas)
• store procedures, functions, constant and
  variable declarations available to every form in
  the project
• MDI Parent Form Files (.frm)
• container window that can hold several forms
• Class Files (.cls)
• objects created in VB

Standard VB Controls

• Label
• Text Box
• Command Button
• List Box
• Combo Boxes
• Frame
• Image Box
• Picture Box

Visual Basic for Applications (VBA)

• programming language which can be found in a
  number of Microsoft Windows applications
• developed by Microsoft as a variation of VB to
  provide a Windows-compatible programming
  environment

VBA Set Up for Intellicad

1. Define an Intellicad object.
2. Establish link between Intellicad and VBA.
3. Create subroutines which can be loaded from
   Intellicad.

VBA Set Up for Intellicad

• Step 1 Define an Intellicad object.
• Intellicad object defined is the Intellicad
  Document.
• Global Doc As IntelliCAD.Document
• Object is defined in VBA Module File(.bas) so
  that it can be accessed anywhere in the project

VBA Set Up for Intellicad

• Step 2 Add VBA object to project.
• VBA object (.frm) is added to the project in a
  manner similar to VB (drag drop).
• UserForm.frm is added to project.

VBA Set Up for Intellicad

• Step 3 Establish link between Intellicad and
  VBA.
• Bind Intellicad document Doc to drawing file in
  use (drawParts.DWG) whenever VBA UserForm1.frm is
  called.
• Private Sub UserForm1_Initialize()
• Set Doc drawParts.ThisDocument
• End Sub
• Intellicad objects such as lines, circles,
  blocks, layers, etc. can now be added and drawn
  to the drawing file.

VBA Set Up for Intellicad

• Step 4 Create subroutines which can be loaded
  from Intellicad.
• Public Sub main()
• Load UserForm1
• UserForm1.Show
• End Sub
• This function loads UserForm1.Public functions
  defined in module files (.bas) can be called from
  the Intellicad interface.
