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"

LogVSAccessor: Warning: Couldn't access Visual Studio

Hello all, this issue has been plaguing me for almost a month now. it seems that UE4 cannot recognize Visual studio when it is running. It won't hot compile (I know that hot compile is always a hit or miss, but this is different from normal hot compile issues.) You are also unable to access a running version of Visual Studio because of this:

 InSolutionPath = L"../../../../../Documents/Unreal Projects/MyProject/MyProject.sln"
 Filename = L"C:/Users/minec/Documents/Unreal Projects/MyProject/MyProject.sln"
 //please not these are the values that debugging shows me, and are not hard coded into UE4.    
 FString Filename(OutPath);
 if (Filename == InSolutionPath)
 OutDTE = TempDTE;
 AccessResult = EAccessVisualStudioResult::VSInstanceIsOpen;

This snippet of code is found on lines 221 -228 of VisualStudioCodeAccessor.cpp As you can see the FStrings are similar but not the same and I'm not quite sure why. The if statement always fails of course and so UE4 opens up a new instance of VS, and compiles the already saved code.

Product Version: UE 4.18
