python - system calling with arguments and pipe -


i have text in variable called mytext, , want run command this:

mytext = "this text"     call("echo" + mytext + " | mail username -s subj")

it means want echo text in mytext , pass mail command thru pipe. right way ?

you should have os command such popen allows create pipe make processes communicate between each other. check out page

from subprocess import popen, pipe p1 = popen(['echo', mytext], stdout=pipe) p2 = popen('mail', stdin=p1.stdout)

this should work.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
