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"

About Create Proc

I have an executable file "process1.exe". For this file, when it is start up, it will automatically, start up another executable file "process2.exe"

Below codes allow me to execute "process1.exe" in UE4, but cannot start up "process2.exe"

 FString Test = TEXT("D:\\projects\\p_name\\exe_folder\\process1.exe");
 process = FPlatformProcess::CreateProc(*Test, NULL, false, true, true, NULL, 0, NULL, NULL);

"process2.exe" is not start up, would probably because of the incorrect working directory. So, I modify the code as below:

 FString Test = TEXT("D:\\projects\\p_name\\exe_folder\\");
 test = FPlatformProcess::CreateProc(TEXT(".\\process1.exe"), NULL, false, true, true, NULL, 0, *Test, NULL);

However, "process1.exe" and "process2.exe" both are not start up.

What is wrong for my code?

Thank you.
