Removal of the IE icon from the desktop on Windows Vista

As I use FireFox as standard internet browser, I would like to remove the IE icon from the desktop.
Unter XP it was quite easy.

Revision Control - Subversion, Mercurial or Git

At the moment I am reading an article on the revision control system Mercurial in a special edition of the german computer magazine c't ("c't extra Programmieren").
I am wondering, which revision control system is the best for my needs. I suppose Mercurial is the one, though I read at some blog that you can not delete unused branches. Everything is from the begining is kept.
A tool that fits to my needs should be easy to learn and easy to use. The students should get used to that tool fast. I also think that the often as disadvantage decribed immutablility of Mercurial could be an advantage in my case. So no one is able to delete branches by mistake.

Documentation of the FFmpeg API

Well, I only know this site as API documentation for the FFmpeg library. cekirdek.pardus.org.tr/~ismail/ffmpeg-docs/
Unfortunateley I have to mention that the documentation is really poor. There exists a better docu for the CLI.

If someone knows a better documentation or description of the classes, methods and so on, please let me know.
Well I just found this wiki.multimedia.cx/index.php?title=FFmpeg_codec_howto, it might help.

VPN and Access Connections

I have just read something about using the software Access Connection in addition with a VPN client.
It seems, that you only have to adjust a few more settings.
Tomorrow I will test the new settings at work.
If the new settings work, I will post the solution with step by step instructions.

Here the Link to the german ThinkPad group and the answer.

Edit from 2009-07-29:
This is really weird. I tried the solution from the mentioned link, but unfortunately it did not work.

Edit from 2010-01-23:
I forgot to mention that I solved the problem.
The problem was caused by the Intel software for the WLAN network adapter. When I had a look at the available network adapters, there were displayed three adapters for the WLAN connection. After deinstalling all components of the Intel(R) PROSet/Wireless Wifi-Software, everything is working fine.

I deinstalled the components as shown in the screenshot above.

My Lenovo ThinkPad X200, Vista and Cisco VPN Client

I have really trouble with connecting my notebook to the WLAN at work. The VPN Client connects successful, but I only get local access and no internet access. The problem does not exist, if I use the LAN adapter and the VPN Client.

I am not sure if the software "Access Connections" causes this trouble.

Building OpenCV using CMake and MSVC90 Express Edition

The Express Edition of the Microsoft Visual C++ Studios do not support OpenMP. But by default this option is enabled, if you use CMake to generate the solution and project files for OpenCV for the Visual Studio.

If you create the solution and projects, the debug version will compile without any errors. But the release version won't.
If you run CMake and load the CMakeLists.txt file there is an option called ENABLE_OPENMP. Disabling this option does not suffer the problem. You also have to remove the value /openmp from the entry OPENCV_EXTRA_C_FLAGS_RELEASE.
Now you may generate the solution and projects for the MSCV90 Express Edition and the release version will compile without any errors.

FFmpeg on Windows

For downloading the FFmpeg library I used TortoiseSVN as SVN client. TortoiseSVN is easy to use.

After installing MinGW and MSYS, I succeeded in runing the configuring and make scripts.

I did not like to install the libraries into a subdirectory of MSYS, because MSYS is installed on the same partition than windows. For my data I use a separate partition.

I would like to know if there is any effort in installing the libaries and dlls into the specified subdirectory of MSYS (I can't remember the name of the directory at the moment).

OpenCV using FFmpeg on Windows (MSVC90)

This topic is driving me crazy.

There are a lot of instructions on how to build OpenCV with FFmpeg support on linux, but none for windows using MSVC90. I searched a lot, but without success.

Indeed there exists a really good instruction for building FFmpeg on windows using MinGW and MSYS. Unfortunately I found it after I had gotten rid of all these things. But if I will have to install MSYS again, I will have a look on this.

I would like to use this blog for knowledge exchange on topics like programming with libraries like OpenCV, FFmpeg and so on.
