I figured out most of my previous problems and did encounter a new one. This is how far I got until now. I found a database which is prodviding the coordinates for each "zip code" within Germany my other SQL database contains. Now i want to map the sales figures onto the map and create charts within the boundaries from the states of Germany.
I also am trying to do all this with C# and in the source code.
I hope one can understand, what I am trying to do.
Thanks in advance for any help
