I have a list of names in a listbox. What I would like to do is have a certain selected name change color, from red to green, when I click a button.
Thank you

Don't add the name directly: add the HTML-ized version of the name.
htmlname = sprintf('<HTML><BODY bgcolor="%s">%s', 'red', ThisEntryName);
And in the callback:
namestr = cellstr(get(hObject, 'String'));
validx = get(hObject, 'Value');
newstr = regexprep(namestr{validx}, '"red"','"green"');
namestr{validx} = newstr;
set(hObject, 'String', namestr);

I have already looked at this article and unfortunately it doesnt work for what i want to do...
in the listbox with the names i can either add or delete the names.
the html method would not work for me
any other ideas? thank you

What you are generally describing above should work with HTML... can you post a few pictures of what you envision? Or can you post the cell-string you are using to apply to the listbox... there might be a formatting issue that is preventing it from working.

Walter, i'm not sure what do you mean or what to do with this line or where to add it. By name do you mean string name or listbox name?
Don't add the name directly: add the HTML-ized version of the name.
htmlname = sprintf('<HTML><BODY bgcolor="%s">%s', 'red', ThisEntryName);

@Vincent: You wrote "I have a list of names". Then just add the HTML stuff to one of the names to get it colored.

What i ended up doing is this:
contents = cellstr(get(handles.Names_Listbox,'String'));
NewText = contents{get(handles.Names_Listbox,'Value')};
NewColor = sprintf('<HTML><BODY bgcolor="%s">%s', 'green', NewText);
set(handles.Names_Listbox,'Value',[])
set(handles.Names_Listbox, 'String', cat(1, get(handles.Names_Listbox,'String'), NewColor))
it works great THANK YOU. however, is there a way to move the new colored text to either the top of the list or to stay in the same place that it was initially?
Walter, I tried to follow your exemple in the callback but for some reason didnt do anything for me.
Thank you
