Q: I get the following error:
"FATAL ERROR: Unhandled Access Violation Reading 0x0004 Exception at
3009fd10h"
A: This is related to objects from ADT in the drawing. It might also be in
connection with use of dbConnect. It could be either visual or not visual ADT
objects within the drawing. To fix the drawing run RECOVER. Then -WBLOCK using
*.
Q: When using TRIM or EXTEND I get the following error:
"FATAL ERROR: Unhandled Access Violation Reading 0x0000 Exception at 892a7ch".
A: (Fixed in 2004) This
occurs when there is an xref with custom arx-objects (could be from ADT, MDT or
some 3:rd party application) that you try to trim to and you don't have that
application installed or an Object Enabler for it. There is an error in
AutoCAD's TRIM and EXTEND code in which it doesn't handle trimming or
extending against a proxy in an xref properly. Workaround is to draw a
temporary object and trim or extend to that one instead of the one inside
the xref.
+OPTIONS default value doesn't work correctly. (Found in 2002 and is still
there in 2006)
Enter the command +OPTIONS and press enter you would suppose to get to the
first tab but you comes to the second. To solve this you have to enter 0 as
the Tab index to get it correct.
When creating a PDF with Adobe PDF Writer there might be problems if you're
using TTF-fonts. You can notice the bug if you have TTF-text in modelspace
and in paperspace having a viewport that clips the text. The text doesn't
event have to be clipped, just close to the edge to be invisible in the
PDF-file. Solution is to use Distiller instead.
Sometimes Adobe PDF Writer can crop/cut TTF-font-text even in paperspace. Solution is to use Distiller
instead.
Q: True Type fonts plot beyond boundary of floating viewport when plotting
layout. This only affects True Type Fonts.
If you create a connection with dbConnect to a SQL Server you will run
into problems if the table name is starting with numbers. Prefix the table
name with a letter and it will work better.
Q: I have freestanding labels, linked to a database, in a drawing
containing multiple lines of text
(Description, Part Number, etc..). The labels are setup to be a specific
width (i.e. 3").
Is there a way to maintain the width of the labels when they are reloaded or
can you
programmatically restore certain properties of the label (i.e. the width)
after reloading the label.
A: After you reload, open the label edit dialog box and press OK.
Q: The scenario is the following. I have an Access 97 database with values
that is not showed correctly with
dbConnect. To reproduce it make a simple database with a table with values
in a series
like this: 0.01,0.02,0.03,...
When looking at the values in Data View of dbConnect the values shows up
like below:
0.01,2.9999999999999999E-2,4.0000000000000001E-2,....,0.10000000000000001,
etc.
A: dbConnect is just reporting the number that Access stores. Access
is storing the number in industry-standard binary form, which entails
conversion from and to the decimal numbers people keep insisting on using. Many
numbers which are easily represented exactly in decimal form are infinitely
repeating decimals in binary form and cannot be represented exactly in a
finite number of binary digits. When you convert such a number from decimal
to binary and than back again, what you get out is not exactly what you put
in. The ultimate problem lies in the fact that you're using a binary
digital computer. At http://www.fmsinc.com/tpapers/math/
it's described in detail.
There is a bug in AutoCAD 2002 (fixed in AutoCAD 2004) that don't let you save changes to the
registry by code. According to an Autodesk developer: "Looking at the code,
we only save these settings via the Options dialog, closing down AutoCAD, or
when we close all documents and enter a "zero-doc" state."
You will notice the problem by using any API command (Visual LISP or VBA) that
should save the settings to the registry profile.
This workaround solves the problem. Run this code below before exporting a
profile or setting it current or something like that by code, otherwise many
setting will not be saved.
1) (getenv "Toolbars\\ACAD.TB_zoom")
2) Move the toolbar "zoom" manually
3) (getenv "Toolbars\\ACAD.TB_zoom")
4) Nothing happens
5) (startapp "wscript" "R:/OptionsClose.vbs")
6) (getenv "Toolbars\\ACAD.TB_zoom")
7) Now it works and you can see that the changes where saved to the registry!
But the above code will not work within one Lisp/VBA session since Options
command can't be called transparently. The external code has to end with calling
the rest of the internal code.
Below is an example how to do it from within VBA code:
Public Sub subExportProfile()
Shell "wscript R:\OptionsClose.vbs"
End Sub
Public Sub subImportProfile()
Dim preferences As AcadPreferences
Dim currActiveProfile As String
Dim strProfileToImport As String
Set preferences = ThisDrawing.Application.preferences
currActiveProfile = preferences.Profiles.ActiveProfile
preferences.Profiles.ExportProfile currActiveProfile, _
"r:\TestProfile.arg"
strProfileToImport = "TestProfile"
On Error Resume Next
preferences.Profiles.DeleteProfile strProfileToImport
preferences.Profiles.ImportProfile strProfileToImport, _
"r:\TestProfile.arg", True
preferences.Profiles.ActiveProfile = strProfileToImport
End Sub
Save the following code to a vbs file named OpenAndCloseOptions.vbs or you
can make an exe-file in VB of it.
' Start from AutoCAD with
' (startapp "wscript" "r:/OptionsClose.vbs")
' or from VBA with Shell "wscript R:\OptionsClose.vbs"
On Error Resume Next
Set AcadApp = GetObject(, "AutoCAD.Application")
Set AcadDoc = AcadApp.ActiveDocument
AcadApp.Visible = True
Set WshShell = CreateObject("WScript.Shell")
WshShell.AppActivate AcadApp.Caption
WshShell.SendKeys "OPTIONS ", True
WshShell.SendKeys "{Esc}", True
' Call the rest of the VBA code to continue
WshShell.SendKeys "{(}vl-vbarun ""subImportProfile""{)} ", True
I got a problem with the dialog boxes where AutoCAD 2002 and AutoCAD LT 2002
browses for files. It took more time than before and for folders with hundreds
of files it took forever. It was so slow.
I checked with File Monitor from www.systeminternals.com
and found the following. Compared to a PC where this problem where nonexistent
AutoCAD where not reading the file stream information like SummaryInformation on
each file in the folder.

Solution at last!
I hunted this down. I don't know what else this setting is for but by
changing it everything works fine. Do you know what this byte do?
Set the two-digit value in the 17:th byte to 00. Many of the other bytes are
controlled by settings that is controlled via Explorer > Tools > Folder
Options > View.
Observe that you have to manually change this one byte in REGEDIT. You have
to restart AutoCAD to have the effect.
I can't get the all different values extracted from the attributes.
I would like to have the three values
STND-N-YY-1015;STND-N-YY-1010;STND-N-YY-1011 extracted.
The result below means nothing to me. How can it? I don't know in what drawing
'STND-N-YY-1010' comes from and the value 'STND-N-YY-1011' isn't showed at all,
except as a number included in row 1. But that value shows 'STND-N-YY-1010'.
Autodesk answer on the above bug was:
"The reason why the CSV file looked something strange is because the same
Block Name is existed in several files. So the same Block Name after the second
file will append the filename at the end of the Block Name with a '~' in
between. This is the behavior of the design for this command."
Another problem I have in a Swedish environment is that XLS-file from EATTEXT
creates everything in one column instead of multiple ones.
Conclusion is that EATTEXT is useless for at least my needs.
Update: Unfortunately this was not making it to be solved for AutoCAD 2004 or
AutoCAD 2005. But for AutoCAD 2006 it's almost solved. Everything seems to work
well except it's not possible to get the file path and name extracted.
