Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Can't Open ws2_32.lib

I'm having problems getting Unreal to work correctly. I am running Windows 10 and this computer has only run Windows 10. Before I installed Unreal, I had VS Community 2015. Once I installed Unreal 4.17 I saw that it was meant to work in VS 2017 so I installed VS Community 2017 with the Game Dev option that includes the Unreal Engine (I didn't re-install Unreal at this time). After that I uninstalled VS 2015 using the default uninstaller. Later when I tried to compile the code in my projects I kept getting link errors trying to open ws2_32.lib My computer has 4 copies of WS2_32.lib. I tried uninstalling and reinstalling the Unreal Engine (just through the Epic Games Launcher) and I was able to open a project and work with it until I needed code then it said that I would have to do something to get the code integrated or something (sorry I can't remember). After playing around a bit I found I still couldn't compile my code in VS or Unreal because of the same error. I also found that Unreal despite being 4.17.1 is still using VS 2015 as default despite VS 2015 being uninstalled. I switched it to use 2017 as default and now I can't create any new project of the type Basic Code and I can't open my original project because it needs to rebuild because it's using an old version of the engine. Here's an error message for when I tried to create a new basic code project.

Try reinstalling visual studio 2015 with all the C++ tools. This worked for me.
