The file has already been opened in the plugin_host?

#1

I created a file with a plugin ,when I opened it with Shellexecute ,an alart window pop up say:the file has already been opened in the plugin_host.
Can the file be disconnected from the plugin_host?

presumably you just need to close the file handle in your Python code after creating the file

code is below

    1. They work fine outside plugin, try to close the file in plugin ,error message is :str object has no close attribute.

from ctypes import *
import subprocess
import tempfile
import os
import re
from threading import Thread
import time

if os.name == “nt”:
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
startupinfo.wShowWindow = subprocess.SW_HIDE

pdf_filename = tempfile.mkstemp(prefix=‘sublime_text_graphviz_’, dir=None, suffix=’.pdf’)
file_full_path = “F:/study/Proprac/mytest/atool/graphviz/record.dot”
args = [‘dot.exe’, ‘-Tpdf’, file_full_path, ‘-o’, pdf_filename[1]]

process = subprocess.Popen(args, cwd=os.getcwd(), stderr=subprocess.PIPE, startupinfo=startupinfo)
print(pdf_filename)

def get_output(out, process):
for line in iter(out.readline, b’’):
# queue.put(line)
errstr=re.sub(’\r\n’,’’,line.decode(‘utf-8’))
print(errstr)
print("#"*102)
print("#"*30, “‘end print’”, time.asctime(time.localtime(time.time())), “#”*33)
out.close()

t = Thread(target=get_output, args=(process.stderr, process))
print("#"*102)
print("#"*30, “‘start print’”, time.asctime(time.localtime(time.time())), “#”*32)
t.daemon = True # thread dies with the program
t.start()

def open_graphics(pdffile):
try:

    shelldll = WinDLL("C:/Windows/System32/shell32.dll")
    nret = shelldll.ShellExecuteW(None, 'open', pdffile, '', '', 1)
    print(nret)
except Exception as e:
    raise e

open_graphics(pdf_filename[1])

    1. * To append two line to block try,change the try block as below ,the plugin works ok now.

try:

shelldll = WinDLL("C:/Windows/System32/shell32.dll")
nret = shelldll.ShellExecuteW(None, 'open', pdffile, '', '', 1)
print(nret)

os.close(pdffile[0])
os.unlink(pdffile[1])
