need help creating standalone gui using m-file (no fig file, not using GUIDE)

Asked by Jude Kastens on 24 Feb 2011
I created a GUI in editor (not GUIDE) using just an m-file (no fig file). I then used deploytool to build & package (no problems with this).
Everything installs fine (including MCR) on a non-MATLAB PC, but upon running the GUI EXE, the EXE appears briefly in the task manager process list and then quickly disappears, and the GUI does not appear at all. Also, a beep can be heard, suggesting an error and not just a successful (but really fast) open & close.
Is there some protocol I need to follow when trying to create a Windows standalone GUI in this manner (i.e., not using GUIDE & no fig file)? Do I need to initialize the m-file (and/or any created figures) in some particualr way?
Using R2010a, Windows XP, & Windows 7 (all 64-bit).
Thanks in advance for any advice/suggestions.

Let me add that I have tried to run the GUI EXE from the DOS prompt just to see what happens, and received the following error:
Input argument "h" is undefined.
MATLAB: inputArgUndefined
Here are the beginning lines of my code, in case this helps expose what I'm missing:
function [] = fldplnfigGui
opengl software
scr = get(0,'Screensize'); % Get screensize.
scrctr = [scr(3)/2 floor(5*scr(4)/8)];
% Main Figure object
h.fldplnfig = figure(...
'Color',[0.9608 0.8706 0.7020]); % wheat
From here, I go right into initializing variables & laying out the controls on the figure. 'h' is a structure that I drag around and manipulate everywhere with all the important information that different parts of the GUI need.
Thanks much, Paulo!
Instead of replacing the figure handle, I simply initialized h ("h = struct;"), and the standalone seems to work now.

Paulo answered in comments:
try fldplnfig instead of h.fldplnfig in the figure handle
