Title: Topics for a VBA Tutorial
Post by: CmdrDuh on May 03, 2005, 05:31:35 PM
Please post what kind of topics you would like to see in a VBA tutorial.  Please try to keep this thread on topic.  EX. I would like a utility to turn all my graphics to Color=ByLayer and Linetype=ByLayer

for tutorial topics i would like a tutorial on how to 'use' the utility created.
for specific utilitiesi would like a utility to create layers.
"" to insert blocks from specified location

both of those are good topics.  Espically the first b/c VBA doesn't offer an EASY way to make a shortcut.

1 ) Entity manipulation and creation.

2 )  File I/O.

In that order.

I would like a utility to ...

How 'bout start a new job/open existing job.
New job would give an interface (dailog?) to enter pertinent info like job name, number, customer, etc. and create a folder, populate the titleblock info & save everything to a drive location.  Existing job would either open an existing dwg for editing, or add a new dwg to the existing folder.

IOW, no more creating folders or browsing thru them in windoze.

Ok, that's easily do-able Birdy.  Although, isn't this what the wonderful folks at Autodesk gave us the Sheet Set Manager for? :D  J/k.

The entity manipulation is also a very good one.  VBA gives us almost total control over all the aspects of a drawing object's properties, but very few of the modifications are available directly. (ex. trim, break, move, copy)  You can still do all of those, but you have to know your way around to be able to pull it off.

For file I/O, are you talking about text files, or dwg files?

heh, "blocks" will be fun.  Since "blocks" and "blockreferences" are two terms that don't come into AutoLisp very often.

As a given, any tutorials will seem easier for those versed in V-Lisp vs. those who only know AutoLisp.  V-Lisp uses many of the same terms as VBA, and the way of manipulating objects is also somewhat similar.

I think that we can also work in the topics that Mark mentioned (private and public subs and functions) at the same time.

No, but maybe. Depends on how cruel you want to be to your non-conformists.  Say for instance they created a wrong layer name, you can search the entire drawing for non standard names, and move all the graphics on those layers to another layer.  Then they would have to sort out the mess on the correct layers.  Or you could just delete it and make them do it again.

Well, you "could" do something a little more sneaky .... how about turning off the ability to create layers altogether .. force users to use a template with the layers already defined. It can be done ... but it won't be pretty

Like undefining the commands or deeper than that?
Title: Topics for a VBA Tutorial
Post by: Keith™ on May 04, 2005, 09:55:47 AM
Well, like an API that disables the "new" button in the layer dialog, removes the "new layer" option from the popup menu and intercepts the "layer" command from the command line.

Unfortunately, the only real way to prevent the making of layers is to have an event fire when a layer is created, check against a list of authorized layers then have the unauthorized layer deleted. The question becomes how to deal with any entities on the layer when you want to delete it ... such as when inserting a block .. any layers in the block are automatically created

Personally CMDuh, I think if you started with the basics, like how to use and test code in the ide, how to use the watch window, and other debugging tasks and the importance of indenting and commenting code. That would be a great start. You'll have some heavy hitters like Keith and Ben, but the majority of us are mush brained when it comes to starting vba. Myself, being knowledgeable in Vlisp, it wouldn't take too long to grasp this after getting through the basics, but until then, I'm a mush brain with vba.

Thats hard b/c that would be my opinion... There are the obvious ones like COMMENT you code, but we all know that, we just dont always follow thru.  There are some good guidelines that I'm putting in the getting started guide I'm making.  Hopefully that is what your looking for.

You can count me in as far as offering advice from time to time ... I won't soon be able to actually manage teaching a class, but I MIGHT over the course of the next few weeks put together an API primer ... Those who are familiar (intermediate) with VB(A) will likely want to look toward expanding its usefulness.

Keith:
I hope to see something like this from you. The Windows API is something I've yet to venture into in VBA and a primer course would be very nice. Judging by what I've seen from you in the past I'm sure it would be a worthwhile read.

MP, its funny that you sent me there, b/c I read that just this morning.  Whats also funny is I teach by that very principle.  What I meant about being a hacker is I have no formal trainging in VB(A) so the methods I will be showing are what I know. (Which is sometimes not the best way to get the job done)  Also, I dont program for a living, so by someothers standards, that makes me a hacker not a programmer.  Either way, I dont care, because if it helps me get my job done faster or more efficiently, its a program.

Has anyone tried applying VBA in other programs? I have several macros in Excel as well and quite frankly, enjoy it more then CAD at times.

The irony is that it helps me approach programming better in AutoCAD.

Anyone who is in this forum is very fortunate. I have learned a bit from different people and a lot from others.

I still have a long way to go but I have also come a long way in VBA. So anyone in this forum (with persistence) can learn just as I am.

OK, this is jumping ahead, but here is that program.  I will have to look to see who gets credit for this.

Code: [Select]

Private Sub AcadDocument_EndCommand(ByVal CommandName As String)

'***Below code is to AUTO save the drawing every 25 commands,
  If ThisDrawing.GetVariable("DWGTITLED") = 1 Then 'don't use on new, unsaved drawings
  Select Case CommandName
    Case UCase("undo"), UCase("u"), UCase("zoom"), UCase("z"), UCase("pan")
        command_count = command_count
    Case UCase("QSAVE"), UCase("SAVE")
        command_count = 0
    Case Else
        command_count = command_count + 1
        If command_count = 25 Then 'change this to any number you want
            ThisDrawing.Save
            command_count = 0
        End If
    End Select
  End If
End Sub

It needs to be placed in the ThisDrawing module of the Acad.dvb (or any dvb that will always be loaded)  For those of you who do not know where that is, I will be covering that in an upcoming handout.

I use VBA in Word, Excel, AutoCAD, Access, in fact only today I developed a small application in Word for my colleagues over in the US.

truth be told, I'm a lazy sonofa.... so if I can develop something that will save me doing something twice, then I'll do it.
