CarrotSticks a great way to train math skills for kids

I love math and knows the importance and value of it. I can definitely recommend this for your kids. You can play CarrotSticks here and try it out first without even registering. Kids can practice and play for themselves or compete with peers and learn the fun of math.

Run-time error '429': ActiveX component can't create object solution for VBA 64-bit

Code like this will result in error in AutoCAD Architecture 2010 64-bit:
Set SchedApp = New AecScheduleApplication

Or this in AutoCAD 2010 64-bit:
Set SSM = New AcSmSheetSetMgr

One method that seems to work is to move the code from within a sub to the declaration like this:
Private SchedApp As New AecScheduleApplication

Another method is to replace it using GetInterfaceObject like this:
Set SchedApp = ThisDrawing.Application.GetInterfaceObject("AecX.AecScheduleApplication.6.0")

The reason is that VBA runs as an out-of-process client in 64-bit applications.

Unfortunately this also means that Sheet Set Manager API cannot be used in 64-bit applications because it is a COM server that cannot be called from another process as opposed to an ActiveX server.

Another 64-bit related problem is in AutoCAD Architecture 2009/2010 and AutoCAD MEP 2009/2010. In Tools>References the AutoCAD tlb shows up but not for the verticals. The same problem is also in .NET if you look at the COM tab when adding references.

The solution for this is a fix in the registry that look like this:

@="C:\\Program Files\\Common Files\\Autodesk Shared\\AecXBase60.tlb"

It needs to be done for each tlb you want to use. There is a win64 key but the win32 key is missing so it needs to be added.

Here is also a Microsoft KB describing similar problems with Office.

Speed up Windows 7 logon with 30 seconds

Consider the following scenario:

  • You have a computer that is running windows 7 or Windows Server 2008 R2.
  • You set a solid color as the desktop background.
  • The Desktop Window Manager Session Manager service is running.
  • You log on to the computer locally.
In this scenario, the Welcome screen is displayed for 30 seconds during the logon process.

See details in this hotfix or just change the background to using a picture that can be a solid color.

Decode FlexNet/FLEXlm license files

Everyone having a reason to look at a FlexNet license file knows that it can be pretty cryptic as well as to know what all Feature Codes are.

The License File Parser site Autodesk has put up allows you to easily convert the contents of your Autodesk license file into an easy to read report. Among other pieces of useful information, the report contains the full name of the licensed product, the serial numbers, and the number of seats.

Simply go to, click the "Browse" button, locate your license file and then click the "Submit License File" button.

Here is what the result might look like:

If you also want reports for license usage either historically or for the moment take a look at JTB FlexReport where you for example can produce an HTML report like this.

I wonder what stats is?

Distributed File System (DFS) Problems in AutoCAD 2010

DFS have never been officially supported even though I my experience have not had any problems. But now there is issues if you use an AutoCAD 2010 product.

Knowledge Base document: Distributed File System (DFS) Problems in AutoCAD 2010

You are experiencing problems with AutoCAD 2010 (or a vertical product based on AutoCAD 2010) not working with DFS.

Although Autodesk does not officially support using the Windows Distributed File System with AutoCAD and AutoCAD-based vertical products, it has been known to work properly in the past and many customers use DFS with our products.  We have recently identified two separate issues that can affect DFS usage.

The first problem is the inability to open a DFS folder from the File Navigation dialog in AutoCAD 2010.  This problem has been corrected in Update 1 for AutoCAD 2010.  If you are using AutoCAD LT 2010, or a vertical product, you should apply the Update for that product that includes Update 1 from AutoCAD.  For most vertical products, that will also be Update 1 however, for AutoCAD Civil 3D, that will be Update 2.

The second problem is the inability to open folders on a DFS share by double-clicking.  This is mostly seen on Vista SP2 and Windows 7 and is due to changes Microsoft made in those operating systems to change a folder to a link.  For file folders that won’t open using double-click, the recommended work-around is to pick the Open button instead.

SmartPurger update available

After the posting SmartPurger 3.0 for AutoCAD scripting now with 64-bit support there is now available an update of SmartPurger with version number 3.0.4 that fixes some of the regression bugs from 3.0. Update is available free for existing customers.

Retrofits game by Autodesk for Greener Buildings

Autodesk wants to raise awareness about the benefits of greener, more sustainable buildings and of course to sell some software (nothing wrong with that though).

Buildings are the leading cause of green house gas emissions so it makes sense to “Don't Just Stand There. Make Buildings Better” as the slogan is.

Follow on Twitter at and
visit to play the game. You won’t see me make it to the leader board as I’m not that good.

Is Google Public DNS useful for me?

Google has released Google Public DNS recently so I decided to give it a try and here is my review and result.

I wondered if I should switch to it or not in case it would speed up my Internet browsing experience. Are my DNS nameservers impeding my Internet experience?

To the rescue comes the Domain Name Speed Benchmark that was an excellent tool and that actually informed me that my local ISP provider were much quicker. At least right now and here. I also had “Obtain DNS server addresses” selected but the tool found in the conclusion that the second in the list was quite quicker than the first one so I decided to add them manually in the best order and hopefully things will runs smoother now than before.

Autodesk University Virtual

I won’t be at AU 2009 in person but virtually. See you there.

Good thing too that Autodesk invited all ADN members to AU Virtual at no charge.

PS. I noticed that the date on the banner is showing only December 1-3 while it should be December 1-4.
