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"

Return Handle from callableBlueprint


I am programming a bluetooth low engergy plugin right now. I already got a hard programmed connection to my heart rate monitor working, but now I want to make it more flexible. For some reason I get a compile error, when I have a function that returns a HANDLE.

my .h file:

     UFUNCTION(BlueprintCallable, meta = (DisplayName = "Return handle", Keywords = "BLE handle"), Category = "Bluetooth LE")
             static HANDLE returnHandle();

my .cpp file:

 HANDLE UBLEBPLibrary::returnHandle()
     HANDLE test = NULL;
     return test;

When compiling Visual Studio throws the following error: OtherCompilationError (5)

This doesn't help me in any way. Any Ideas?

Thanks for your Help!
