Welcome there !

As soon as Sharepoint was available, I tried to install it on a virtual box running a fresh Windows 2008 Web Edition.

Got the following error : Application Server Role, Web Server (IIS) Role: configuration error

Based on log, it appears that the role "Application Server" is mandatory, and of course, this role is not available on Web Edition of windows 2008 Server so you must run at least Standard Edition, that's it !

Also, if you wonder changing your virtualization platform, before running to VMWare (which has poor performance for me), I advise you to look around VirtualBox (free, fast, x64 support, snapshot...)

Update :
Anyway, it seems that we can get around this limit by editing the installation files : http://msdn.microsoft.com/en-us/library/ee554869%28office.14%29.aspx

A year after the 1st release of the document library treeview webpart, I decided to improve the webpart to provide a better interface/ergonomic experience.

Expected result is something that looks like Windows Explorer and that remove all those annoying postback/refresh of pages.

The video talks by itself !

As good geek discussion, with some colleagues we were wondering how was implemented the string conditional operator in C#.

Here's a quick comparaison between a "classical" if-then-else and a string ? condition. The analyze focus on the MSIL code generated.

Basic C# condition :

String foo = "myString";
String aa;
  
if (foo.Length > 0)
    aa = foo;
else
    aa = String.Empty;

and the MSIL code :

   1:  .method private hidebysig static void  Main(string[] args) cil managed

   2:  {

   3:    .entrypoint

   4:    // Code size       34 (0x22)

   5:    .maxstack  2

   6:    .locals init ([0] string foo,

   7:             [1] string aa,

   8:             [2] bool CS$4$0000)

   9:    IL_0000:  nop

  10:    IL_0001:  ldstr      "myString"

  11:    IL_0006:  stloc.0

  12:    IL_0007:  ldloc.0

  13:    IL_0008:  callvirt   instance int32 [mscorlib]System.String::get_Length()

  14:    IL_000d:  ldc.i4.0

  15:    IL_000e:  cgt

  16:    IL_0010:  ldc.i4.0

  17:    IL_0011:  ceq

  18:    IL_0013:  stloc.2

  19:    IL_0014:  ldloc.2

  20:    IL_0015:  brtrue.s   IL_001b

  21:    IL_0017:  ldloc.0

  22:    IL_0018:  stloc.1

  23:    IL_0019:  br.s       IL_0021

  24:    IL_001b:  ldsfld     string [mscorlib]System.String::Empty

  25:    IL_0020:  stloc.1

  26:    IL_0021:  ret

  27:  } // end of method Program::Main

String conditional operator :

String foo = "myString";

String aa = foo.Length > 0 ? foo : String.Empty;

MSIL code :

   1:  .method private hidebysig static void  Main(string[] args) cil managed

   2:  {

   3:    .entrypoint

   4:    // Code size       26 (0x1a)

   5:    .maxstack  2

   6:    .locals init ([0] string foo,

   7:             [1] string aa)

   8:    IL_0000:  nop

   9:    IL_0001:  ldstr      "myString"

  10:    IL_0006:  stloc.0

  11:    IL_0007:  ldloc.0

  12:    IL_0008:  callvirt   instance int32 [mscorlib]System.String::get_Length()

  13:    IL_000d:  ldc.i4.0

  14:    IL_000e:  bgt.s      IL_0017

  15:    IL_0010:  ldsfld     string [mscorlib]System.String::Empty

  16:    IL_0015:  br.s       IL_0018

  17:    IL_0017:  ldloc.0

  18:    IL_0018:  stloc.1

  19:    IL_0019:  ret

  20:  } // end of method Program::Main

What can we conclude ? The conditional operator is not that bad and may help you to optimize a little bit more your code. One argument in favor of the classical if-then-else is that it may be more readable (I don't necesssary agree) but on the other side, does slightly more operations and instantiate one more variable in the stack.

To finish, I think that no-one will notice a difference of performance between the two methods so use the one you feel the more confortable.

Have a look at XPath Query Helper, a very simple tool that will help you to build your XPath queries. Project was sleeping on my hard drive and I thought that someone may be interested in.

Sick of hiring monkeys to type paragraphs, use the =rand(x,y) feature of Word (x = number of paragraph, y= number of lines of each paragraph).

You can also use the =lorem() function that will type the following :

Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas porttitor congue massa. Fusce posuere, magna sed pulvinar ultricies, purus lectus malesuada libero, sit amet commodo magna eros quis urna.
Nunc viverra imperdiet enim. Fusce est. Vivamus a tellus.
Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Proin pharetra nonummy pede. Mauris et orci.

A small but usefull screen-capture tool. Just a small exe, manage the Vista's transparent mode ...

I used to think that Ad-Adware was surely the best removal tool for trojans & spywares and I felt very disappointed where it failed on a well known spyware (Hotbar). I tried Spybot : Search & destroy and then spyware went to the paradise of malwares !

A 5 star award for Spybot-S&D !
