MATLAB: Listdlg, giving memory to list dialog from previous execution.

listdlglistdlg memory

Hi,

I am using a list dialog in my code, allowing user to select the desired items. I want to introduce some kind of memory to the list dialog so that it remember the previously selected items.

Right now i am using following code for the list dialog. For example

r = {'Crunchy','Creamy','Natural','Chocolate'};
[Selection,ok] = listdlg('ListString',r);
for i = 1 : length(Selection)
   some operation...
end

In above example if user has selected Crunchy and Creamy Then i want that next time "Crunchy" and "Creamy" should be pre-selected in the list dialog.

Thanks in advance for your suggestions, tips and hints.

Kind regards, \\ Arsalan

Will this do what you want?

r = {'Crunchy','Creamy','Natural','Chocolate'};
Selection=[];
for k=1:3
  [Selection,ok] = listdlg('ListString',r,'InitialValue',Selection);
  % Do more stuff
end

MATLAB: How to get integer data using inputdlg,, or using any other way

Here's a way to force the user to enter an integer:

% Ask user for a number.
defaultValue = 45;
titleBar = 'Enter a value';
userPrompt = 'Enter the integer';
caUserInput = inputdlg(userPrompt, titleBar, 1, {num2str(defaultValue)});
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.
% Round to nearest integer in case they entered a floating point number.
integerValue = round(str2double(cell2mat(caUserInput)));
% Check for a valid integer.
if isnan(integerValue)
    % They didn't enter a number.  
    % They clicked Cancel, or entered a character, symbols, or something else not allowed.
    integerValue = defaultValue;
    message = sprintf('I said it had to be an integer.\nI will use %d and continue.', integerValue);
    uiwait(warndlg(message));
end

Lucky for you, I already have a code snippet for you.

% Ask user for one integer number.
defaultValue = 45;
titleBar = 'Enter an integer value';
userPrompt = 'Enter the integer';
caUserInput = inputdlg(userPrompt, titleBar, 1, {num2str(defaultValue)});
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.
% Round to nearest integer in case they entered a floating point number.
integerValue = round(str2double(cell2mat(caUserInput)));
% Check for a valid integer.
if isnan(integerValue)
    % They didn't enter a number.  
    % They clicked Cancel, or entered a character, symbols, or something else not allowed.
    integerValue = defaultValue;
    message = sprintf('I said it had to be an integer.\nTry replacing the user.\nI will use %d and continue.', integerValue);
    uiwait(warndlg(message));
end

Feel free to adapt as needed.
