python - Subprocess crashes unexpectedly from PyDev, works fine from double click in windows explorer -


i've spent quite bit of time trying figure out. i'm trying invoke line run abaqus (an fea program):

popen = subprocess.popen(callcommand, cwd=workdir, creationflags=subprocess.create_new_console) popen.wait()

when double clicking on .py file everthing works fine. on running eclipse, abaqus crashes:

this application has requested runtime terminate in unusual way. please contact application's support team more information.

then later "smapython.exe has stopped working".

i've played around admin privilege settings no avail. don't have rep tag abaqus.

the solution (which i've come accross after writting draft question) found here:

http://sourceforge.net/p/pydev/discussion/293649/thread/94a76ecb/

basically, pydev adds environment variables don't play abaqus, turn them off following code can used:

import os try:     os.environ.pop('pythonioencoding') except keyerror:     pass # call abaqus...

hopefully of use someone, i've spent 2 days fixing this. bit of niche use of pydev (i'm not programmer, i'm civil engineer) think more powerful have eclipse take care of source files. abaqus cae files binary , proprietary source control , custom edits pain otherwise.

i guess in case solution trace problem taking bits of off , checking works , differences are.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
