VBA Downloads for AutoCAD

I have uploaded a couple of additional sample VBA projects to my website that can be downloaded.  Below is an overview of the 4 samples that are currently available.

CustomDblClickEdit - This example is used to demonstrate how you can replace the standard functionality of the Double Click Editing inside of AutoCAD of your own handler. This allows for changing the default editors and the way objects are handled. Some what out dated with AutoCAD 2007, but if you are using a previous release and what to customize the actions that are performed when double clicking objects, you will want to check this one out.  Last updated for 2004, but will still work with 2005 and 2006 though.

SheetCount - This example is used to demonstrate how to create a custom sheet set property that holds the total number of sheets for all the sheets in the sheet set file. Project was originally developed with AutoCAD 2005 and later tested under AutoCAD 2006. A new version is now available for download that will work with AutoCAD 2007.

SummaryInfo - This example shows how to list, create and modify both standard and custom drawing properties for the current drawing. This is a great example to build on if you want to automate the population of custom properties that you want to use with fields in text objects.

The VBA sample code download page is available by clicking here. Check back once in a while as I will be uploading new samples as I have time to clean some of them up.  You never know what might show up on the site.  Stuck on trying to figure something out in VBA, just let me know and I will see what I can do about putting together a sample project file for you.  Looking for some AutoLISP sample code, well click the jump to access our AutoLISP downloads page.

AutoCAD ActiveX History Reference

Do you find yourself maintaining multiple releases of AutoCAD and need to know what ActiveX functions existed in which release? Maybe you are on an older release and want to know what might have been added. A fellow read and visitor of my web site has shared with me his cross reference table of all the ActiveX Methods and Properties from AutoCAD 2000 through 2006.  Many thanks to Marc for sharing this.

Chapters 11 - 13 all wrapped up

I have finished putting the final touches on Chapters 11 - 13 for my VBA book this past weekend.

Chapter 11: Storing & Retrieving Data for Future Use
This chapter focuses up working with System Variables, Windows Registry, XData and XRecords.

Chapter 12: Modifying Objects in a Drawing
This chapter focuses up on modifying objects that are already in a drawing.  It covers things like Mirroring, Copying and many other methods that are used for modifying objects.

Chapter 13: Formatting with Colors, Linetypes, Lineweights and Layers
This chapter focuses on formatting properties of an object.  These include work with True Colors along with Layers, Linetypes and Lineweights too.  I also take a look at Layer States and how they can be used to help working on drawings.

I will give an update on what is going on for the next chapters once they have been completed.  As you can see the chapter outline has been revised compared to the original list of chapters that I put together.  As I was working through many of the chapters, things came up before they were talked about so I had to revise the order of some of the content.  If you have any questions or comments just let me know.

Sincerely,
  Lee

Chapters 1 - 10 are Complete

I have completed the first 10 chapters of the VBA book that I am working on.  This month has been very busy with the new addition to my family and some other things going on.  Below is a breakdown of what is in the first 10 chapters that span almost 200 pages, 198 pages to be exact.

Introduction

Chapter 1: AutoCAD Commands for VBA
Covers the commands that are available in AutoCAD for working with VBA projects.

Chapter 2: Visual Basic Editor
General look at the various tools that are in the Visual Basic Editor (IDE)

Chapter 3: Code Modules
A breakdown of what you can find in a code module and what a code module is.  You will learn how to work with procedures, variables, data types and general error handling.

Chapter 4: UserForm (Dialog Boxes)
You will learn how to add controls to a UserForm and how to manipulate both controls and the UserForm at design-time.

Chapter 5: Basic VBA Functions & Conditional and Looping Statements
A look at some of the most widely used functions that VBA has to offer.  These include string and data conversion procedures, and working with mathematics.  The chapter also covers working with While and For loops, among much more.

Chapter 6:  AutoCAD Entities - Part 1
A look at some of the basic entities that can be added to a drawing and are found in the AutoCAD Object Library.  These are objects like AcadObject and AcadEntity which are the base for objects that can be added to a drawing file.  Then it starts covering objects like Lines, Circles, Arcs and many others.

Chapter 7: AutoCAD Entities - Part 2
A continued look at entities that can be added to a drawing, but these are the complex entities.  Objects like Polylines, Hatches, Splines and many others can be found in this chapter.

Chapter 8: Document Object
This chapter focuses on the Document object which represents the Document window and the database objects that hold the contents of an open drawing file.  It also takes a look at the preferences of the Database, Drawing Properties, File Dependencies and how to work with collections.

Chapter 9: Application Object
This chapter focuses on the Application object which represents the actual AutoCAD session and allows for accessing all the open drawings.  You can also find information about the application preferences, which normally you find under the Options command of AutoCAD.

Chapter 10: User Input Outside of a UserForm
You can find information on how to get information from the user at the Command Line in this chapter.  I have also included some information that I have gathered through out the years to help improve the process of working with the Command Line based input methods.

I should be complete with the next three chapters over the next couple of days and will post an update after they are complete.  Thanks to everyone that has posted comments or have sent me an e-mail on what they would like to see included in the book, so keep the information and concerns coming.

Sincerely,
  Lee

VBA Book Project in Progress

I have been working on and off for some time on whether or not to release a VBA book that covers in great depth from what I have ventured down the path in the past.  I am proud to announce that I will be going forward with this project and if anyone out there has any feedback to what they would like to see I am open to listening to them.  Below is a summary of the chapter titles that will be included in the VBA for AutoCAD book.  The book once completed should be some where in the neighborhood of 26 chapters and over 450 pages.  I am hoping to have it completed in the next couple of months.

Chapters
Introduction
1. AutoCAD Commands for VBA
2. Visual Basic Editor
3. Components of a VBA Project
4. Error Handling and Debugging Code
5. Conditional and Looping Statements
6. Basic VBA Functions
7. Object Browser and Getting Help
8. AutoCAD Entities - Part 1
9. AutoCAD Entities - Part 2
10. AutoCAD Document
11. Application Object
12. User Input Outside of a UserForm
13. Storing & Retrieving Data for Future Use
14. Modifying Objects in the Drawing
15. Formatting with Colors, Linetypes, Lineweights and Layers
16. Annotation - Text, Tables and Dimensions
17. Blocks and Xrefs
18. Selection Sets
18. Views and Zooming
19. Layouts and Plotting
20. Manipulating the AutoCAD UI (Menu bar and Toolbars)
21. Responding to Events
22. Accessing Files and Folders
23. Working with the Internet
24. Accessing Other Applications from AutoCAD
25. Odds and Ends
Appendixes, Glossary and Index

I have read many different VBA books throughout the years and some just seem to be way to intense or just not very basic for the beginner.  I hope to be able to bring a blend of content that will help those that are new and familiar to VBA programming in AutoCAD.  I have been using VBA with AutoCAD since R14 so I have been using it since the beginning.  I hope to show a variety of samples that some might have never seen before.  Like I mentioned earlier I would like to hear what people would be looking for in a book that they might be interested in purchasing on VBA for AutoCAD.

Sincerely,
  Lee

Mini Guide for Intro to VBA for AutoCAD

   For sometime now I have had some people asking about whether or not I would do an eBook on VBA for AutoCAD.  I have had one for a while, but until recently it wasn't up to date.  A new version has been created that is a total of 17 Chapters and 169 pages.  Typically people want to see a copy of it before buying it which is understandable.  So What I have decided to do instead was publish a Mini Guide which contains certain sections of the full version.  Below are two links to a scaled down version of the eBook that is titled "Introduction to VBA for AutoCAD".

  If you are interested in purchasing a copy of the full version just e-mail me, otherwise enjoy the Mini Guide to VBA for AutoCAD without any strings attached.  Hope you enjoy the Mini Guide on VBA to AutoCAD.
