When installing Eclipse on Kubuntu, install on /usr/local, otherwise you may have issues with the plugins install

CDT
- tab spaces not taken into account (Helios, Ubuntu 64 bits)
- Needed to do a "apt-get update" after installing CDT otherwise, gave me funky compile error messages on printf and stuff
- To access the gdb CLI, select the gdb process node in the Debug view. The gdb command line will then be available in the Console view. Though no prompt is visible, you can enter commands at the bottom line of the Console view. Doing so may desynchronize the IDE and gdb, so be careful when driving the debugger using this interface.
- automatic save: Windows > Preferences > General > Workspace

cmake

create a sibbling directory of the sources root: search-l-2S-build

cd search-l-2S-build

cmake -G "Eclipse CDT4 - Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ../search-l-2S

In eclipse CDT:

File > Import Existing Projects into Workspace > Next

Select root directory => Répertoire "cmakebuild" créé plus haut

Source accessible in "Subprojects".

./eclipse_cdt -vmargs -XX:PermSize=512m -XX:MaxPermSize=512m -Xms1024m -Xmx1024m

J2EE
You just get "Dynamic Web Project" creation menu only when you install J2EE Eclipse version

Useful files
- eclipse.ini

if you get black zones within the Eclipse editor, you will have to switch from GTK3 to GTK2. To do this, add the following two lines to eclipse.ini

--launcher.GTK_version

2

Software sites

maven2 - http://download.eclipse.org/technology/m2e/releases

Problems

when using the maven plugin, the "Java build path" in the Eclipse will take the default JRE Eclipse config unless you specify "maven-compiler-plugin" as artifact in the pom.xml with version 1.8 for example

Formatting
window->Preferences, ensuite choisir Java->Code Style-> formatter et sélectionner "Java conventions [build-in]".

C# survival kit

* C# is the first “component oriented” language in the C/C++ family

* csharp string <--> C++ wchar_t
* to display a string from multiline (somewhat equivalent to the C++ backslash ):
string toto = @"toto
toto";
* One must specify “override” to the method in the subclass if one want to override a virtual method from the superclass (as opposed to C++ where override is automatic)
* Mutexes are of two types: local mutexes and named system mutexes. If you create a Mutex object using a constructor that accepts a name, it is associated with an operating-system object of that name. Named system mutexes are visible throughout the operating system, and can be used to synchronize the activities of processes.

Registry (Windows autologon, colors)

How to do it trough the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
String Value: DefaultUserName=domain/Administrator
String Value: DefaultPassword=up...
String Value: AutoAdminLogon=1

also possible is DefaultUserName=username

If you have a color problem from Remove server client (Ubuntu):

XP Mode with 32 bit color + integration is possible!
I found an easier way to get 24 bit colors with integration on here.
1. Run regedit in XP.
2. Navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services].
3. Add a DWORD Value named "ColorDepth" w/o parenthesis.
4. Right-click it, modify, then put "4" in the Value data.
5. Restart XP mode / Reboot

SVN survival kit

> Hello, somehow when I update the repository, another username/password is being use.

Tortoise SVN | Settings | Saved Data | Authentication Data | Clear

That will clear the stored information, and you will be prompted for
it the next time it's needed.

Other useful commands:
- svn list svn://whatever.com
- svn status --show-updates --verbose | sort -k 2rn | less
- svn log --verbose --limit 10
- svn status -u (same as --show-updates, svn status usually doesn't check the repository, except when using -u, it just add a * when a file needs updating)
- delete directory
- - svn delete directory
- - svn ci -m " " directory

tagging
- svn copy -m " " svn://192.168.0.1/seng/trunk/ svn://192.168.0.1/seng/tags/2.4/
- svn move -m " " svn://192.168.0.1/seng/tags/2.4/trunk svn://192.168.0.1/seng/tags/2.4/2.4.0.a1

Status values
A: Resource is scheduled for Addition
D: Resource is scheduled for Deletion
M: Resource has local Modifications
C: Resource has Conflicts (changes have not been completely merged between the repository and working copy version)
X: Resource is eXternal to this working copy (may come from another repository). See «svn:externals»
?: Resource is not under version control
!: Resource is missing or incomplete (removed by another tool than Subversion)
~: Something is messed up
