    <p>Continuing my struggle against GUI's, I have run into another road block.</p> <p>Ive successfully created a button that opens a file as a string, and places it in a text box in my GUI like so. </p> <pre><code> [filename, pathname] = ... uigetfile({'*.m';'*.mdl';'*.mat';'*.*'},'File Selector'); set(handles.Textbox1, 'string', fullfile(pathname,filename)); </code></pre> <p>But now I cannot seem to use a function on the acquired file. Ive tried doing </p> <pre><code> str = get(handles.Textbox1,'string'); Histogram(str); %Histogram is a function that I created. </code></pre> <p>But im getting the following errors</p> <blockquote> <p>??? Error using ==> Histogram Too many input arguments.</p> <p>Error in ==> VarunGUI>pushbutton2_Callback at 94 Histogram(str);</p> <p>Error in ==> gui_mainfcn at 96 feval(varargin{:});</p> <p>Error in ==> VarunGUI at 42 gui_mainfcn(gui_State, varargin{:});</p> <p>Error in ==> @(hObject,eventdata)VarunGUI('pushbutton2_Callback',hObject,eventdata,guidata(hObject))</p> <p>??? Error while evaluating uicontrol Callback</p> </blockquote> <p>Is my code for calling the function to blame, or is the function itself? I'm having trouble understanding how to alter the function to work on the called image, so that may be my problem, the function begins with the following code. </p> <pre><code>function Histogram clear; clc; fid = fopen(''); myimage = fread(fid, [512, 683], '*uint8'); fclose(fid); </code></pre> <p>Is there a certain variable I need to place in the '' to make the GUI act in the manner to which I would like it? Question ran a little long, but please tell me if there is anything else you need to see in order to assist me, any guidance or tips would be great. Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
