When we create a simple script with gui, it should be nice to puts the icons in the source script,
so whe can diffuse the code without any packaging.
This code create a ruby source which declare some file-content coded in ASCII/.base64
In the source, he put get_icon_filename(name) which put content to a temporary file and return
the filename created :
# usage: ruby gene.rb ../angel.png face_crying.png face_smile_big.png > icons64.rb
require 'base64'
require 'tmpdir'
str=<require 'base64'
require 'tmpdir'
$icons={}
EEND
lvar=[]
ARGV.each { |fn|
varname=File.basename(fn).split('.')[0].gsub(/[^a-zA-Z0-9]+/,"_").downcase
File.open(fn,"rb") { |f|
str+= "\n$icons['#{varname}']=< lvar << varname
}
str+=<<'EEND'
def get_icon_filename(name)
raise("icon '#{name}' unknown in #{$icons.keys}") unless $icons[name]
fname=File.join(Dir.tmpdir,name+".png")
puts "#{name} ==> #{fname} / #{$icons[name].size}" if $DEBUG
File.open(fname,"wb") { |f| f.write($icons[name].unpack('m')) } unless File.exists?(fname)
fname
end
EEND
puts str
STDERR.puts "#{lvar.join(", ")} done size=#{str.size}."
This generate a code like :
require 'base64'
require 'tmpdir'
$icons={}
$icons['angel']=<iVBORw0KGgoAAAANSUhEUgAAAFAAAAB9CAYAAAA1I+RFAAAABHNCSVQICAgI
....
Hc7GYuTuE23+EVbG/wE7dk77N6cYpQAAAABJRU5ErkJggg==
EEND
$icons['face_crying']=<iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAABHNCSVQICAgI
fAhkiAAAAAlwSFlzAAAN1wAADdcBQiibeAAAABl0RVh0U29mdHdhcmUAd3d3
...

LtAAAAAASUVORK5CYII=
EEND
$icons['face_smile_big']=<iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAABHNCSVQICAgI
.....
IQlXZwKuzrjtNLc0aDs1ABcd0k6ypVidf+6Owx6Eu22ZAAAAAElFTkSuQmCC
EEND
def get_icon_filename(name)
raise("icon '#{name}' unknown in #{$icons.keys}") unless $icons[name]
fname=File.join(Dir.tmpdir,name+".png")
puts "#{name} ==> #{fname} / #{$icons[name].size}" if $DEBUG
File.open(fname,"wb") { |f| f.write($icons[name].unpack('m')) } unless File.exists?(fname)
fname
end
Here a little Shoes app for use raster content
require 'green_shoes'
<< "contents of 'icons64.rb' here" >>
Shoes.app do
stack {
background "#A0A0B0".."#A0A0FF"
$icons.keys.each { |name|
para name
image get_icon_filename(name)
}
}
end
Or a Ruiby app (see https://github.com/raubarede/Ruiby):
require_relative 'Ruiby/lib/ruiby.rb'
<< "contents of 'icons64.rb' here" >>
class X < Ruiby_gtk
def component()
stack do
$icons.keys.each do |n|
flow {
slot(label(n))
slot(label("#"+get_icon_filename(n) ))
}
end
end
end
end
Ruiby.start { X.new("test",100,100) }

Following is grid view code for aspx page.
Width="100%" OnRowDataBound="gv_RowDataBound">
Following code evaluates each row of grid:
protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblStudentName = ((Label)e.Row.FindControl("lblStudentName"));
Image imgControl = ((Image)e.Row.FindControl("imgControl"));
lblStudentName.Text = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "StudentName"));
imgControl.ImageUrl = (Convert.ToBoolean(DataBinder.Eval(e.Row.DataItem, "Present")) ? "Images/Checkmark.png" : "Images/Cross.png");
}
}
