For most IDE, such as eclipse, Intellij, Processing, and other, it seems that even after pinning the program to the task bar, when I actually open it, it creates another program that is not pinned to the task bar. As a result, I have multiple icons on the taskbar. I'm guessing that the ones I pinned on the taskbars are kind of like launching applications and they open a separate application, not that I'm sure of this theory, but I'd prefer to have only one application showing up on the taskbar. So, is there a way to set it up so even after I start the program, another doesn't show up on the taskbar? Also, It seems like I can't pin the program that gets opened. Here's a picture of the taskbar. Or, since it seems like I can't post a picture yet, This is what's going on with my taskbar. http://i1320.photobucket.com/albums/u538/jerichoi224/Untitled_zps216034f9.png
This is because IDEs launch instances, which Windows doesn't support taskbar pinning for.
The solution for Eclipse IDE is to add:
-vm
C:/path_to_jre/bin
, to the beginning of the eclipse.ini file, in the eclipse directory, and relaunching the IDE.
