How can I open a file in a compiled application?

I have a trial license for the Matlab compiler. I would like to build an application to display .fig files. I have created an application that opens a Figure window. However, when I try to open a .fig file, I get an error message "Warning: The Open function cannot be used in compiled applications". Is this a limitation of the trial license, or does it apply to all compiled applications in general?

"when I try to open a .fig file" - please post the corresponding code.

Just to confirm, Jan's suggestion is correct. To compile a standalone Figure viewer:

• Create a file (e.g., FigViewer.m) with the code below:

[fileName,dirPath] = uigetfile('*.fig','Select a figure (.fig) file');
openfig(fullfile(dirPath,fileName));

• Then compile it in the main command window with the compiler:

mcc -m -v FigViewer.m 
% or, version without prompt 
mcc -e -v FigViewer.m

The error message is clear in this point: You cannot use open in compiled applications. This is not a limitation by the trial version.

What about openfig?

The compiled application is very simple - it just opens a figure window. The issue is not being able to use the "File | Open" functionality in the figure window. The aim here is to provide people who have no Matlab license, no Matlab knowledge or experience, and no command-line skills with a tool they can use to view .fig files. If it can't be done, then I will look for other approaches.

Again: Please post, with which code you try to open the figure. This would allow to suggest a solution.

Sorry; I guess I wasn't clear. There is no code. It's a figure window. The "Open File" button in the figure window, when clicked, causes a "File open" dialog to pop up, but when a file is selected and OK is clicked, nothing happens. In the terminal window from which the figure window compiled application was launched, I see the error message, "Compiled applications cannot use the File Open function."

It is clear that I'm barking up the wrong tree here, and I don't want to waste any more of anyone's time. Thanks for trying.

@Tom: Please do not post comments in the section for answers. Use the section for comments instead. Thanks.

"I would like to build an application to display .fig files" - this is possible and not hard to implement.
