Hi,
I have made a MATLAB GUI which has two buttons. I want to perform some tasks on CallBack event of both these buttons.
I have obtained a variable FileName when the first button is pressed. But as soon as the function of first button ends, the variable gets deleted. I want to use this variable when the second button is pressed which is obviously a different function. Since, the first function variable is deleted as soon as the function ends, how can I use this variable within the second button's function.
I know how to do it by saving it as .mat and recalling it but it will make the GUI interface unfriendly. Can you please tell me another way to save a variable before the first function ends and recall it later in the second function?
Thank you.

Hi Asad,
before the "first button" function end use
mydata.value = "directory result"
setappdata(gcf,'mydata',mydata);
At the beginning of the "second button" function use
mydata = getappdata(gcf, 'mydata');
disp(mydata.value); % shows the value

Actually the first button is the browse button. So, in the first button function, I have this code:
[FileName,PathName]=uigetfile
FullPath=[PathName FileName]
Now, I want to use this FullPath variable to be passed to second function. Can you tell me how the above code lines should be modified according to these variable names?
