[EDIT: 20110722 11:00 CDT - reformat - WDR]

I have an array of strings,i would like to display that string in listbox,so i use,

contents = get(hObject,'String')
selectedText   = contents{get(hObject,'Value')};
switch selectedText 
    case'(default)'
        set(handles.listbox7,'string',[])
    case 'Simply Supported Beam'
    set(handles.listbox7,'string',['432';'3234';'534']) 
    case'Cantilever Beam'
    set(handles.listbox7,'string',['436';'768';'3463'])
    case 'Truss'
         set(handles.listbox7,'string',['324';'886';'435']) 
    case 'Plate'
        set(handles.listbox7,'string',['546';'4534';'576'])
    case 'Shear Building'
         set(handles.listbox7,'string',['456';'465';'234'])   

end
guidata(hObject,handles)

When I do that, I get an error saying:

 Error using ==> vertcat

 CAT arguments dimensions are not consistent.

Here's a test program that illustrates the problem:

??? Error using ==> Trial1>popupmenu13_Callback at 618

E.g. "['432';'3234';'534']" is not proper. It would create a CHAR matrix like:

['4', '3', '2';
 '3', '2', '3', '4';
 '5'm '3', '4']

As you see, this is not rectangular. What do you want to appear in the listbox7 object? For a multi-line text use:

{'432';'3234';'534'}
