Pass variable from python script to C program(command line argument) -



Pass variable from python script to C program(command line argument) -

i here issue : have gui (wxpython), has spinctrl, output of spinctrl must sent c file, take command line argument, whenever execute c file using subprocess accepts value gui spinctrl value must sent instead of manual typing.

my code is:

ps = "password" var1 = self.sc1.getvalue() var2 = self.sc2.getvalue() subprocess.call(['echo xsxsxs | sudo "./license.exe"', str(ps), str(var1), str(var2)],shell = true)

whenever run script doesnot show output/error :(

if remove echo xsxsxs| sudo line 4 , execute show error: "you must root user","invalid password", "segmentation fault".

whenever utilize shell=true subprocess.popen (or 1 of convenience wrappers), should pass string way type in shell, not list.

from docs:

if shell true, recommended pass args string rather sequence.

python c wxpython subprocess wxwidgets

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
