This is what I have : Code: var filehandle; ... function check_file_existence () { filehandle = file_open_read ("gameresults_1.txt"); if (filehandle > 0) { do } else { do } } The engine does not find the file and says so. Quote: W1518 Can't find file .................. What is the correct code for this situation?

My code is: Code: filehandle_n = file_open_read (Map_name); //�ffne Map.txt if(filehandle_n != 0)//falls es existiert { do something } else { printf("Map existiert nicht!"); } and it works finem even without file. I think that problem is in an other part of your code

In the manual under warn_level : 0 - no warning messages. 1 - warnings about problems with some hardware configurations (default). 2 - warnings about bad texture sizes and wrong parameters in engine functions. 3 - warnings about missing files in file functions. 4..6 - even more warnings. so you probably have warn_level at 3 or higher and everything works as planned ^^ get the C# wrapper: for A7.85.4 and A8.30.4, Version 2.3.9 at http://acknexwrapper2.matthias-auer.net/ or visit the thread
