Site with truckload of Lenovo Service and Support Training information (including ThinkPad FRU, videos and specs)

Posted by jpluimers on 2011/04/15

Browsing the Lenovo web-site always takes a long time, and sometimes it is hard to find the right search phrase to soom in quickly.

The Lenovo Service and Support Training site has a nice treeview on the left that allows you to quickly find what you are after.

For instance, a friend wanted to know if 12.5 mm HDD’s would fit in the Serial Ultrabay Enhanced spot on a W70x series ThinkPad.

Presto: the treeview quickly lead me to http://www.lenovoservicetraining.com/ion/PSREF/O-W700.pdf

PS: 12.5 mm HDD drives do fit, but you need a 3rd party caddy for them (see search query below) or use the official caddy for 9.5 mm drives and live with a small gap.

Search query: 12.5 mm SATA HDD Caddy LENOVO Thinkpad Serial Ultrabay Enhanced, then follow the link and search for W701 or W700.

PS2: if you want to add a 2nd 9.5 mm HDD in a regular HDD bay, then you need at least the HDD Rubber Rails as specified in the ThinkPad W700, W700ds, W701 and W701ds Hardware Maintenance Manual on pages 92 and 105 (FRU part number 41V9756), but it is better to follow the Drive Rails and Caddys for the ThinkPad W700’s internal drive bays guide and get you this combination or browse to the million parts webshop , then in the “Shop Search”, search for “Lenovo Thinkpad T60 T60p Hard Drive Caddy Cover”.

Visual Studio 2010: you should run the Remote Debugging Monitor from a local drive to avoid 0x8007000E E_OUTOFMEMORY

Posted by jpluimers on 2011/04/14

Setting up remote debugging is always a precarious thing, no matter what kind of development platform: the online documentation tells you the standard steps, but usually they don’t suffice.

This case is Visual Studio 2010 remote debugging, where the development environment is on a workstation running Windows 7, and the debug target is on Windows Server 2008 R2.
Both are x64 versions.

There is a remote desktop connection to the server, and the server can see the workstation files on the \\TSCLIENT\C share.

This is the error when running msvsmon.exe from \\tsclient\C\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger\x64:

[Visual Studio Remote Debugging Monitor]
The following error occurred: Not enough storage is available to complete this operation.

View Msvsmon's help for more information.
[OK]

(Funny BTW that the x64 Remote Debugging Monitor is in fact in an x86 path).

The solution is simple: copy the x64 directory local, then start it from there.

The reason in that the user credentials on the server don’t have enough rights on the \\TSCLIENT\C directory tree, so Windows barfs on it.

This pointed me into the right direction when I started Process Monitor from the same \\TSCLIENT\C share: Read the rest of this entry »

Entity Framework 4 – security warning popup workaround: Do you trust all the T4 “text templates” on your system, even future ones?

Posted by jpluimers on 2011/04/13

When using Entity Framework 4, your transofmrations (model to classes, DB to model, etc) are performed by T4 Text Templates.

Those templates are executed all over the place (when saving your project, building your project, changing your model, etc).

Since anyone can insert a T4 Text Template into Visual Studio, and those are scripts, it is a potential vulnerability.

The default Visual Studio behaviour is to show you a dialog like this:

[Security Warning]

Running this text template can potentially harm your computer. Do not run it if you
obtain if rtom an untrusted source.

Click OK. to run the template.
Click Cancel top stop the process.

[X] Do not show this message again

[OK]  [Cancel]

Some blogs mention Just click OK and feel free to check “do not show this message again.”

I’m not sure I want that: it would indicate I always trust T4 Text Templates, even the ones added in the future (T4 Text Templates are executable content, malicious software could find it’s way into your development environment; anyone remember the virus that hooked itself into the run-time library sources of a development system so it would spread through anything compiled on that system?).

But I also don’t want to click OK on that dialog.

It would be so nice if the dialog:

  1. Showed which template is about to be executed
  2. Allowed me to skip only for that particular template

Anyone better thoughts on this?

c# – List of new features in C#2.0, 3.0 and 4.0 – Stack Overflow

Posted by jpluimers on 2011/04/12

When maintaining software, you can’t always use the latest versions of your tools and languages.

Since C# has added a lot since version 1, it is handy to know what changed in which version.

Of course nothing beets the (paper and electronic!) editions of C# in Depth (covering C# 1, 2 and 3) and C# in Depth second edition (covering C# 2, 3 and 4).

Those books are thick (they need to, there is a truckload to cover!).
(The publisher (Manning) actually did a very good job on the e-book versions. Highly recommended, as it makes searching stuff so much easier).

The answers to the c# – List of new features in C#2.0, 3.0 and 4.0 Stack Overflow question contains a few concise lists of major changes in the language.

I really like the Bluffer’s Guide to C# 2, and the Bluffer’s Guide to C# 3 that Jon Skeet mentioned in his answer (and wish he wrote a Bluffer’s Guide to C# 4 as well), as they focus on some essential stuff in a very concise way.

If you want more detailed info, start with these stackoverflow questions:

Since stackoverflow wasn’t there when C# 2 was introduced in 2005, start with this nice C# 2 overview article on CSharpCorner.

Note: contrary to popular belief, there is no C# 3.5. There is .NET 3.5 (adding LINQ) and .NET 3.0 (adding WPF, WCF and WF) all based on the C# 3.0 and CLR 2 SP1 features.
(Yes, some expression tree features don’t work on CLR2 RTM, as that one has a few bugs, see Jared’s comment on this answer).

avast! antivirus 5: if you updated your engine/virus definitions to 110411-1, then please update them to ‎110411-2

Posted by jpluimers on 2011/04/11

The 1104011-1 engine/virus definitions of Avast contains a problem; it marks a lot of web-sites as and programs as false positives ago.

Right now, their web-sites and download servers are flooded with people frantically trying to update.

Be patient, but do update when you can. The past has shown the flood doesn’t really take that long.

From their Facebook page:

A few minutes ago: ‎110411-2 UPDATE IS OUT! PLEASE UPDATE YOUR DATABASE.

About 20 minutes ago: PROBLEM WILL BE FIXED WITH NEW DATABASE UPDATE SOON, PLEASE BE PATIENT. THANK YOU.

Oh BTW: If you use the FREE version of avast, then you will have a low priority and receive 403-errors while updating for some while:
Last encountered error: Other HTTP error (403)

Spellen is lastig: Het is weer mis met de Chicagostraat – Almere – WebRegio.nl

Posted by jpluimers on 2011/04/11

In Almere is voor de 2e keer een bord met een foute spelling voor Chicagostraat opgehangen (eerst Chigacostraat, nu Chigagostraat).

Gerrit de Jager (Doorzon Daily) wijdde er zelfs een cartoon aan.

Dit doet me denken aan mijn schooltijd; de woorden “Mississippistraat” en “San Franciscostraat” schoten me meteen te binnen: daar moet ik altijd 2 keer over nadenken voor ik ze goed spel.

Gelukkig komen die een stuk minder voor als “Kerkstraat” of “Dorpsstraat” (hoewel “Dorpstraat” ook bestaat).

Spellen blijft moeilijk, en niet alleen Nederlandse woorden :-)

SharePoint 2010 error: Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 800703fa – SharePointWiz

Posted by jpluimers on 2011/04/11

Somehow in a production environment I did get this error too:

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 80040154.

These two posts helped me to solve it:

SharePoint 2010 beta error: Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 800703fa – SharePointWiz – Site Home – MSDN Blogs.

Rhythmic Coding: Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 80040154.

The solution is deceptively simple:

Resolution: It is because you are trying to build a x86 application. Go to project properties and set type to x64 everywhere. Then rebuild and debug. The Error Vanishes!

The SharePoint 2010 dll’s are all x64, and Visual Studio 2010 by default still starts .NET projects in x86 mode for both Release and Debug settings.

Got my Linksys WRT54GL working as a Client Bridge using dd-wrt: Client Bridged – DD-WRT Wiki

Posted by jpluimers on 2011/04/08

My primary wireless router is at the ground floor.

They made a small error when building our house some 15 years ago: all the spare PVC pipes running up stairs that were meant for additional cabling are full of concrete, so no way to get any network cabling upstairs.

I don’t need a lot of band width upstairs, but some of the devices are wired.

Solution:

  1. dig up my old Linksys WRT54GL router with hardware version 1.1
  2. ditch the Linskys firmware from my good old
  3. install dd-wrt mini as described on the dd-wrt Linksys WRT54GL pageI installed build 13064, the currently recommended build in the router database.
  4. run the steps in the Client Bridged – DD-WRT Wiki article (this YouTube video was also instructive, but the steps are better)
  5. connect a wired appliance

In fact, I had to make one change: the primary network is on 192.168.0.X, so the Linksys dd-wrt router is now on 192.168.0.50 (which is outside of the DHCP range of the primary router).

And I took a shortcut: I joined the WLAN of the primary router (on the site survey page)  instead of entering all the WLAN info manually.

It works, and took me less than 15 minutes total.

I could have gone one step less (Client only, which puts your LAN behind a NAT) or one step further: configure it into a Repeater Bridge (instead of a Client Bridge).
That would allow WLAN clients to my WRT54GL as well as LAN clients.
Right now I don’t need that.

Another option is Repeater Mode (where the WLAN and LAN clients of the WRT54GL are on a different subnet than the primary router).

Finally, if you run into trouble, read this thread on the dd-wrt forum on Broadcom based devices it contains a truckload of info in a very concise way.
