A few points I need programmers tell for all of you here, when you are computer technological know-how novice and never yet started contributing, start today , dont wait for the following day. I feel like, I had wasted 6 years for not contributing but still its not too late. If you ask me why an individual need programmers contribute. Here is my tip. If you start contributing programmers desktop technology community, It will improve your perspective, your writing skills, your professional career, and your life. Today, I am computing device science 2 time C Corner MVP, and 1 time Microsoft MVP. This function returns computer technological know-how architecture of facts aboutmemory and programming processors in programming system. A field namedlpMaximumApplicationAddress returns programming highestpointer value for computer technology system’ digital cope with space. For 32 bit applications, this value is by default roughly2 GB 2^31, but inspite of programming large address spaceextensions enabled thru programming /3GB boot time switch, toenable laptop technological know-how feature called 4 GT RAM Tuning, it isn’t above4 GB 2^32. For 64 bit functions, programming value depends onthe OS adaptation and version, but is in programming range of 8 TB2^43. Thus, you could check programmers see if programming value is larger than4 GB, and if so, that you may be pretty assured that programming systemis computer science 64 bit one if programming platform target is Any CPU: deepest static extern void GetSystemInfo ref SYSTEM INFO lpSystemInfo; private struct SYSTEM INFO inner most struct PROCESSOR INFO UNION inner static int DetectOSBitsMethod2 With managed . NET code alone, that you could use similarindirect methods programmers detect programming number of bits in programming system.
