How to pass a structure variable from callback to other callback .

Asked by Vinay kumar Reddy on 17 Feb 2013

Help Needed.

In a GUI M file I got a situation where I should pass a structure Variable form callback to callback.

Here is my code

function Run_Button_Callback(hObject, eventdata, handles)

for i=2:length(sc);

    des=sc{i,2};
    str=sc{i,3};
    Requestor(1,i).UID=regexp(str, '(?<=Requestors UserID:).*(?=Requestors Email Address:)', 'match');

% extracting value and removing spaces....

       Requestor(1,i).UID=strtrim(Requestor(1,i).UID{1,1});
end;

handles.Requestor.UID=Requestor.UID;

guidata(hObject, handles);

function Generate_Button_Callback(hObject, eventdata, handles)

Requestor.UID=handles.Requestor.UID;

Routed_Array=[ ];

for i=1:length(sc)

         Sort_routed=strcmpi(Requestor(1,i).UID,Id(i).Manager);
        Sort_routed=sum(Sort_routed);
       switch Sort_routed
           case 1 
               Routed_Array=[Routed_Array i];
       end;

end;

I need help , I following got error

Reference to non-existent field 'UID'.

Error in ==> MailSend>Run_Button_Callback at 385 handles.Requestor.UID=Requestor.UID;

Please Help

you can use global variables easly to transfer data from one function to another one.

function main
myfun1
myfun2
function myfun1
global a
a.a=5;
a.b=10;
function myfun2
global a
a.a=a.a+a.b
