New category – “wiki”

Posted by Raffael on Posted in Personal stuff, Wiki Tagged

 
Hello together,
I’ll just want to inform you that there’ll be soon a new category. The category will be named “wiki” and gradually filled with articles, which on the contrary to my other articles on this blog, will completely missing my personal touch. The articles should be seen as pure knowledge articles which are totally free from any comments of mine or my personal opinion.
If you now ask yourself, “Why does he do that?” I’ll say, “let me explain it to you.” A couple of times there have been articles where I used techniques and terms whiche are not very common. So as not to bloat these articles with all that nerdy stuff, I will create wiki articles on specific topics, which you can work through, to get the necessary background knowledge for the main articles.
 
 
Greetings,
Raffi

A webcam. For example this one:No products found.
Basic C#-knowledge. If not exists, read this: No products found.

At first you have to reference the both dlls and write the using-statements […]
