Origin Ver. and Service Release (Select Help-->About Origin):
OriginPro 2021 (64-bit)
9.8.0.200
Operating System:Win10 64bit 19044.1415
I use the example code on the official website to realize the connection between external python and Origin. But the problem is that the connection between external python and Origin can only be realized every time the Origin is reopened. It always takes a lot of time to open Origin each time.
I know that using the Originpro package can implement data processing and drawing in the background, but I need to manually adjust the detail styles every time I draw.
I want to use external python for some reasons. I know that the built-in python can easily connect.
So I would like to ask if there is a way, or with the help of OriginPro, to realize the connection between external python and Origin. |

Please use the code below to link to an existing Origin instance. Make sure your originpro module needs to be 1.0.8 or later.
import originpro as op
op.attach()

Thanks, it works as the code below
if op.oext:
op.set_show(True)
# YOUR CODE HERE
origin_output()
op.attach()
set.show() must be added and set the ture value.
and is this attach() function just used for the running python runned by external python? how about the origin runned by click the link on the desktop? Is there some function to realise this?

Yes, it can connect to the Origin launched from desktop.

Following on from this question, please would you advise me if there is a recommended way to accomplish the below task?
1. Check whether there is a running instance of Origin.
2. If so, connect to that instance, so that plots will be generated within in it.
3. If not, start a new instance of Origin.
The context is that I am also trying to automate Origin using the external Python connection. |

This script is doing exactly what you expect:
op.attach()
You can also show the Origin window: op.set_show(True)
or release Origin: op.exit()

Hi James,
Thank you for your reply however I am still having some trouble with this.
I adapted the example Origin code from the website, and based on your answer came up with the code shown below.
However, this fails in that if I run the code without an instance of Origin open, it completes successfully (Process finished with exit code 0) but no Origin project is shown.
I have tried various tweaks but none of these solved the issue. Please would you advise me of what changes are required in order for this to work as described in my previous post?
Thanks and regards,
Conrad
import originpro as op
import sys
def origin_shutdown_exception_hook(exctype, value, traceback):
'''Ensures Origin gets shut down if an uncaught exception'''
op.exit()
sys.__excepthook__(exctype, value, traceback)
if op and op.oext:
sys.excepthook = origin_shutdown_exception_hook
# Try to attach to existing Origin instance
try:
op.attach()
# If this fails, it means there is no existing Origin instance. So create a new one, and make it visible.
except:
if op.oext:
op.set_show(True)
op.new()
# Add a test folder to make sure it is working
op.po.RootFolder.Folders.Add("Test") |

op.attach() will always execute either you attach to an existing Origin instance or create a new one. So you can't use Try...Exception... here. Maybe you can use op.get_show() to check if it connects to an existing instance (return true), or create a new one in the background (return false). See if it works.

Thank you for this suggestion, based on this I tried the following code:
op.attach()
if not op.get_show():
if op.oext:
op.set_show(True)
op.new()
However this also has a problem, because if I run this while an Origin instance is open, it closes it and opens a new instance.
Please would you advise me if I did something wrong, or if there is another way to accomplish this? |

If you have an Origin instance open, op.attach() will connect to that instance. Then the code in the block if not op.get_show(): will not execute. This is what I get when running the code. If I change it to if op.get_show():, then a new project is created in that Origin instance. Is this what you expect?

Thanks again for your suggestion James, but this did not accomplish my goal. When I make your change and run the code with no Origin instance open, it does not open a new instance.
I was hoping for this block of code to function the same way as ApplicationSI in the automation server: https://www.originlab.com/doc/en/COM/Classes/ApplicationSI
That is, open a new instance of Origin if none is open. But if an instance of Origin is already open, generate the Test folder inside it. |

OK. Can you try the code below with and without an Origin instance open, see if it does what you expect?
import originpro as op
op.attach()
op.set_show(True)
op.po.RootFolder.Folders.Add("Test")

I gave this a try, and it successfully attaches if there is an Origin instance open. But if I run it without an Origin instance open, it does not open a new instance.
However I believe that I came up with a solution:
op.attach()
if not op.get_show():
op.exit()
op.new()
op.set_show(True)
op.po.RootFolder.Folders.Add("Test")
I realise this is inefficient, but it was the only way I could get it to behave as required. So if you have a better way please do let me know, but for now I believe this achieves the goal. |

Hi ChemistryGuy,
Would you mind to check if your originpro package's version is 1.1.0?
If not, would you mind to upgrade it to latest first and then re-try Yiming's script?
And what is your Origin version?
PS, you can use following method in originpro package to create a folder
#create a subfolder "test" in same level as current active folder
op.pe.mkdir("../test")

Hi Minimax,
I can confirm my OriginPro version is 1.1.0.
I tested Yiming's code again, and the same thing happened: When I ran it with an Origin instance open, it worked as expected. When I ran it without Origin open, it executed without error, but did not create a new Origin instance.
In case it helps, my other details are:
Origin Version: OriginPro 2022 (64-bit) Beta5
Operating System: Windows 11
Also, thank you for sharing that code and documentation, this was very useful. |

Hi ChemistryGuy,
How did you execute the py code?
like in Windows' Command Prompt? IDLE? PyCharm? or what else? |

I am running the code from PyCharm.
In case it makes a difference my Python version is 3.9 |

OK.
We can reproduce the problem with PyCharm.
We will check soon and update you later. |

Hi
Would you mind to try if following script works in PyCharm?
import time
import originpro as op
op.attach()
time.sleep(1)
op.set_show()
wks=op.new_sheet() |

This code worked the first time I ran it.
But when I ran it twice in a row, Origin crashed.
I submitted the crash report, mentioning that I ran the code provided on the forum.
Also, I am happy to keep testing code if it helps you fine tune the Python library. But if you have other priorities, then the solution that I came up with earlier in this thread works for my needs :) |

Hi ChemistryGuy,
It is appreciated you can help to verify the problem.
We made some changes on the package and would you mind to try following?
1.open the originpro package files folder in Windows Explorer, like following
2. replace the 2 py file with attached modified ones. (it is good to backup the original first)
https://my.originlab.com/ftp/forum_and_kbase/Images/newpy.zip
3. Then retry Yiming's script. Does it work? |

Sorry for my slow reply, I tested these new Python files and Yiming's code (the version with time.sleep(1)) now works.
However, after I run the code, I cannot close Origin because I get the following error: "Origin cannot be closed because it is being controlled by another application".
I do not have this problem with the code that I came up with. So my feedback is that this new Origin library works but it would be great if Origin could be closed afterwards, without using Task Manager. |

Hi ChemistryGuy,
Never mind, it is fine.
The time.sleep(1) script should be not necessary with the new py file.
As to the can-not-close issue, would you mind to add "op.detach()" as the last sentence and then check if Origin can be closed? |

| I tried the code without "time.sleep(1)", and adding "op.detach()" as the last line. It worked perfectly, thank you for fixing it so quickly! :) |

Hi ChemistryGuy,
Origin 2022b is available!
The issue you reported in this post,
py attach failed to work in third party IDE like PyCharm (ORG-24938)
has been fixed in this version.
Please download Origin 2022b from the link below, install and try it.
http://www.originlab.com/demodownload.aspx
We are looking for your feedback! Any suggestion will be appreciated!
Thanks,
Amanda

Hi Amanda,
Thank you for letting me know about this new version. I updated to Origin 2022b and also updated the library to OriginPro 1.1.1.
I then tested the code mentioned above, both for attaching to an existing project and opening a new project. My experience was that both cases now work perfectly!
So thank you for solving this issue and for letting me know! :) |

How to connect external python with running Origin
