.net - Why is GUID attribute needed in the first place? -

-

what necessity guid attribute? why don't let compiler handle automatically?!

if compiler handled automatically, you'd end 1 of 2 situations.

  • a new guid every time compiled - since guids supposed published, fail.

  • collisions - if guid same every time, based on (say) hash of name, multiple projects end using same guid different purposes.

the existing approach - explicit guid gives developers power control these required.

delphi - When I encode/decode SMS PDU (GSM 7 Bit) user data, do I need prepend the UDH first? -

while can encode , decode user data part of sms message when udh not present, i'm having trouble doing when udh is present (in case, concatenated sms). when decode or encode user data, need prepend udh text before doing so? this article provides encoding routine sample compensates udh padding bits (which still don't understand) doesn't give example of data being passed routine don't have clear use case (and not find decoding sample on site): http://mobiletidings.com/2009/07/06/how-to-pack-gsm7-into-septets/ . so far, have been able results if prepend udh user data before decoding it, suspect coincidence. as example (using values https://en.wikipedia.org/wiki/concatenated_sms ): udh := '050003000302'; encoded_user_data_part := 'd06536fb0dbabfe56c32'; // padding, evidently decodeduserdata := decode7bit(udh + encoded_user_data_part); writeln(decodeduserdata); output: "ß@ø¿Æ @hello world" encodeduserdata := encode7bit(decodeduse...
