c# - How do I call a DLL which does a time consuming task? -


enter image description here

in wpf application, have communicate datastor on serial port. want separate communication class library simplicity.

in dll, issuing command datastor , wait 10 seconds receive response back. once response datastor, compile data meaningful info , pass main application.

my question how make main application pause while data external dll , continue processing data dll?

i use .net 4.0

consider calling dll method in new thread

thread dllexecthread = new thread(dllmethodtoexecute);

and providing callback main program dll can executed when complete (this prevents locking on gui).

edit: or simplicities sake if want main program wait dll finish execution subsequently call:

dllexecthread.join();

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).
