excel - how to wait for xlwings to complete python code in vba? -


i calling runpython in vba xlwings module following code:

sub portfolio_optimze() runpython ("import quotes; quotes.get_quote()") solveradd cellref:="$h$18:$h$24", relation:=1, formulatext:="$j$18:$j$24" solveradd cellref:="$b$15:$g$15", relation:=4 solverok setcell:="$h$16", maxminval:=1, valueof:=0, bychange:="$b$15:$g$15", _     engine:=1, enginedesc:=" grg nonlinear " solversolve

how make solveradd code wait until runpython code finished?

some info start with: excel on mac allows external processes write cells when excel idle, i.e. while no macros running. that's why runpython call on mac runs background process kicks in when calling macro finished running.

i suggest 1 of 2 following solutions:

1) program solver part in python, too, example using scipy.optimize.

2) put solver vba own sub , call python. planned feature next version of xlwings, see here, can work around (assuming wb workbook):

app = xlwings.application(wkb=wb) app.xl_app.run_vb_macro('solvermacro')

update, since v0.7.1 supported:

>>> solver_macro = wb.macro('solvermacro') >>> solver_macro()

powershell Start-Process exit code -1073741502 when used with Credential from a windows service environment -

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
