i have generated an executable file of a python code.then i called that .exe file from roborealm using EXECUTE_PROGRAM. i need to access the result from .exe file into ROBOREALM.
My issue is how to use variable value (generated in .exe file ) into roborealm.
Please give suggestions.

If you read the docs at

http://www.roborealm.com/help/Execute_Program.php

you will read about the 'Receive sequence'. Entering something like

[program_response]<cr><lf>

would enter your programs output that it prints to stdout into the 'program_response' variable. Note I just made that variable up ... you can call it anything you want.

Or do you need to transfer binary data?

i just want to update a roborealm variable with integer value like either 1 or 2...
one more confusion..please clarify..
whatever i print in exe file , get stored in "program_response " variable in roborealm?
Thankss alot for  your reply and help

Yes, you can use 'print 1' or 'print 2' in your app to output text that then gets stored in the variable ... give it a try!

Make that

print '1\r\n'

based on the receive sequence (forgot the newline).

The order of the modules is relevant ... I can't tell if that is your issue unless you post your robofile. Its also possible something else is going on but I can't tell since I'm not sure what you are doing. Can you post your robofile? I don't need the file you are executing though as I can simulate those results.

in the file, pop4.exe(created from pop4.py file,attached here) is called upon motion detection.if user selects YES ,1is returned in RR variable res. if user selects NO ,2 is returned in variable res. next res value is checked using if condition...if user selects YES ,another exe file(a7) is called which again gives output either 1or 2 similar to pop4 code. a7 return is taken into res1 variable. next if res1 is 1 COG is calculated and has to be transmitted using serial module, else notjhing to be done. here, various variables like decision has been used just to check the results(no use in main algo)

code for pop4.exe is(exe generated from python code as below)
from Tkinter import *
from tkMessageBox import *
def close_after_2s():
    root.destroy()
if askyesno('MOTION DETECTED!', 'Do You Like To Trigger'):
        print '1\r\n'
else:
        print '2\r\n'

Can you check quickly what happens when you select the "wait for program exit" on the second execute? You have it on the first but not on the second.

Also, select the "latch" condition for the first If statement otherwise even while movement is happening the scripts will be run. Using the latch forces the movement to stop and then start again before those python files are executed.

See if that  helps ...

when   ''wait for program end " is selected, the stdout data is not coming(neither times showing on execute  program console)
please help me out with the issue.

The Execute module wasn't written to accept input not immediately available (such as a person typing in a response). We've re-ordered the module and confirmed that it now works with your python script. Can you download the latest version and give things a try again?

Note, the popup request will stop the pipeline processing which will make the entire app appear frozen until someone provides input.
