I am using this code in MATLAB 7.11 (R2010b) to create a infobox:

function g = infobox(text, header, notneeded)      
if nargin < 2         
  header = 'Info box';     
end          
relWidth    = 0.5;     
relHeight   = 0.1;     
screenSize  = get(0, 'ScreenSize');     
height      = min(1.1*1024, 
screenSize(4));    
width       = min(1.1*1280, screenSize(3));     
% Position of  is relative to screen resolution     
pos = [width*(1-relWidth)/2, height*(1- relHeight)/2, ...
  width*relWidth, height*relHeight]; 
gColor = [0.92941 0.94118 0.9451];          
g = figure('NumberTitle', 'off', ...
           'MenuBar', 'none', ...    
           'Resize', 'off', ...
           'Name', header, ...                     
           'Color', gColor, ...
           'Position', pos, ...
           'WindowStyle', 'modal');          
set(g,'HandleVisibility','off')          
pp = getpixelposition(g);     
uicontrol(g, 'Style', 'text', ...                     
             'String', text,...                     
             'HorizontalAlignment', 'left', ...
             'BackgroundColor', get(g,'Color'),...
             'FontName', 'Calibri', ...
             'FontSize', 14,... 
             'Position', [0.1*pp(3) 0.05*pp(4) 0.8*pp(3) 0.9*pi(4)]);                        
pause(1) 
end

This infobox should close after a while but this does not work:

infobox('test');
close(gcf)

You set the 'HandleVisibility' property of the figure to 'off'. When you do this, gcf does not see the figure. Here is your code (formatted for others to be able to read it!) and how to call it

function g = infobox(text, header, notneeded) 
if nargin < 2 
  header = 'Info box'; 
end
relWidth = 0.5; 
relHeight = 0.1; 
screenSize = get(0, 'ScreenSize'); 
height = min(1.1*1024, screenSize(4)); 
width = min(1.1*1280, screenSize(3)); 
% Position of is relative to screen resolution 
pos = [width*(1-relWidth)/2, height*(1- relHeight)/2,width*relWidth, height*relHeight]; 
gColor = [0.92941 0.94118 0.9451]; 
g = figure('numbertitle', 'off', 'MenuBar', 'none', ... 
         'resize', 'off', 'name', header, ... 
         'Color',gColor, 'position',pos,... 
         'windowstyle', 'modal'); 
set(g,'HandleVisibility','off'); 
pp = getpixelposition(g);
R = uicontrol(g, 'Style', 'text', ... 
        'String',text,... 
        'HorizontalAlignment', 'left', ... 
        'BackgroundColor',get(g,'Color'),... 
        'FontName', 'Calibri', 'FontSize', 14,... 
         'Position', [0.1*pp(3) 0.05*pp(4) 0.8*pp(3) 0.9*pp(4)]) ;
pause(1) 
end %%%END CODE%%%
