VB.NET - Provide predefined creation settings in a class -


i'm writing theming class called formtheme vb.net form application. contains colour scheme information can applied @ runtime form controls. there 3 ways instantiate object:

public sub new()

creates new theme default system colours.

public sub new(byval forecolor color, _                       byval backcolor color, _               byval bordercolor color ... )

creates new theme provided colours.

public sub new(byref existingtheme formtheme)

creates new theme doing 'deep copy' of existing theme.

i provide fourth option create theme based on pre-defined settings, example:

public sub new(byval scheme colorscheme) 'usage: dim mytheme new formtheme(colorscheme.night)

was wondering best way implement this? considered using enum , select case statement in constructor theme based on enum value, work:

enum colorscheme   day   night   city   candy   ... end enum  public sub new(byval scheme colorscheme)   select scheme     case colorscheme.day       'set colors     case colorscheme.night       'set colors     case colorscheme.city       'set colors     ...   end select end sub

before forge ahead, there more standard or 'better' way of doing this?

looks ways of doing it.

you preload colorsccheme in dictionnary

dim colorschemelist dictionnary(of colorscheme, formtheme)

loaded in static constructor , them new like

public sub new(byval scheme colorscheme)     new(colorschemelist(scheme)) end sub

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).
