c# - Change of folder Icon takes longer time to show the updated icon -


i on windows 8 , have c# code changes folder icon.

this works fine takes long time refresh. i've been trying methods such as:

intptr path = marshal.stringtohglobalauto(@"[folderpath]");  shchangenotify(hchangenotifyeventid.shcne_attributes,      hchangenotifyflags.shcnf_patha, path, intptr.zero);  shchangenotify(hchangenotifyeventid.shcne_updateimage,      hchangenotifyflags.shcnf_dword, intptr.zero, intptr.zero);  shchangenotify(hchangenotifyeventid.shcne_assocchanged,     hchangenotifyflags.shcnf_idlist, intptr.zero, intptr.zero);

this doesn't seem have affect on folder icon. refresh screen icon still same icon. several minutes later can press f5 , change folder icon specified.

i've seen ugly ways around know tell windows 'refresh' folder icon programmatically. i've seen dropbox seems instant , i'm thinking there solution.

to change folder icon needs 2 steps achieve this:

step 1. create desktop.ini file inside folder create icon (the "target folder"). step 2. set target folder's attribute "system".

to accomplish these steps, create 2 classes i.e. foldericon, orchestrates steps , iniwriter, has 1 static method called writevalue() wraps writeprivateprofilestring() win32 api function.

to getting these things done in right way, follow code project tutorial:

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).
