VBA run hangs AutoCAD

Everyone,

I'm currently trying to load and run a VBA with the below command in our acaddoc.lsp. When AutoCAD is launched and a new drawing "Drawing1" is opened the VBA is loaded and runs fine. Then when a drawing is opened the loading of the VBA hangs AutoCAD. The last line in the command window is "-vbarun" and nothing else happens.

Here is what I have been able to figure out... When NOT loading the VBA and everything works fine, I launch AutoCAD and get the blank "Drawing1" drawing, then I open an existing drawing, AutoCAD closes the "Drawing1" (because nothing was done to it) and opens the desired drawing. When loading the VBA in the acaddoc.lsp, I launch AutoCAD and get the black "Drawing1" drawing, then I open an existing drawing, AutoCAD closes the "Drawing1" and opens the drawing desired and hangs. If I launch AutoCAD and manualy close the "Drawing1" drawing and then open an existing drawing it opens and runs the VBA.

If anyone has any ideas please respond.

Here is the command that loads and runs the VBA. And the VBA "Tester" only consists of one MsgBox line letting me know it was loaded and ran.

(command "-vbarun" "Tester.dvb!Tester")

Thanks,

 

Well a lot of verbiage and you didn't tell us what you want the app to do!
To begin with, the only reason AutoCAD is closing Drawing1 is because you
have SDI turned ON. Second, don't mess around using the acaddoc.lsp file -
just use vba. Here are the steps:

1. Create a blank text file and save it as ACAD.RX. In this file write one
line:

ACVBA.ARX [if AutoCAD 2004+] --- or ---
ACADVBA.ARX [if <=AutoCAD 2002]

2. Create a blank AutoCAD VBA file named ACAD.DVB

3. In the ThisDrawing module, create a sub named AcadStartup. Anything
within it will run once whenever AutoCAD is intially started. To have
something run once any time a drawing is opened, add code to an event like:

Private Sub AcadDocument_EndCommand(ByVal CommandName As String)
If UCase(CommandName) Like "OPEN" _
Or UCase(CommandName) Like "NEW" _
Or UCase(CommndName) Like "QNEW" Then
MsgBox "Opening or starting a new drawing", _
vbOKOnly, "Event Test"
End If
End Sub

Place these files somewhere within AutoCAD's search path. For a more
detailed explanation, read my column online this month as I am discussing
the loading aand running of vba commands automatically.

Mike,

Thanks for the information and I will be checking out your column at the end of this week. I'm just getting into using vba so I'll have to "chew" on the steps you suggested.

We do have SDI turned OFF. Even with SDI turned OFF and you launch AutoCAD and get the standard "Drawing1" drawing, as long as you don't modify the drawing in anyway and open another drawing, AutoCAD closes "Drawing1" automatically. That's seems to be the key that causes AutoCAD to hang on the vbrun.

I'll be looking for your column... Thanks,
