jQuery show, fadeIn, queue -


i've got html form. user can click on, let's say, 2 buttons: 1 - first buttons fires odata request server (it's not ajax) 2 - second buttons fires other logic.

now show progress bar when action 1) or action 2) executed.

in case of action 2) i've used $(loadingimageid).show() not work, it's if it's not executed immediately. however, if use:

                        $(loadingimageid).fadein().queue(function(next) {                         next();                         self.onsaveorderpress(oevent);                     });

it works expected. can explain why show() not work , fadein() does? besides, when computation ends pop-up shown (and takes few milliseconds show in screen). during waiting time spinning wheel (animated gif) freezes. there way prevent this?

finally, how can catch odata requests? i've tried ajaxstart , ajaxstopand correctly catch of ajax requests. in case i've got odata request server. how work out? thank you.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
