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"

Since I solved my own problem today abiet by accident, here is the cause of the error. You add a c++ class with out Microsoft visual studio (or what ever your compiler of choice is) then save. that creates the missing modules, I guess turn off and reboot the computer then let the program do its thing after downloading the latest c++ distributable. click the project, click yes to rebuild, make sure your hard disk is nice and happy then wait for the program to do the work for you. Silly me after getting my new laptop forgot to download visual studio. Case closed
