-

i'm using vb 2010. problem is:

i can send , display sent command in textbox without problem when try use .exe in cmd can't display in textbox source code is: 

 private results string      'the "delegate" used correct threading issue (can't update control directly in vb.net 08/10), , invokes needed text update.     private delegate sub delupdate()     private finished new delupdate(addressof updatetext)     private sub updatetext()         textbox2.text = results     end sub      private sub form1_load(byval sender system.object, byval e system.eventargs) handles mybase.load      end sub      private sub button1_click(byval sender system.object, byval e system.eventargs) handles button1.click         dim cmdthread new threading.thread(addressof cmdautomate)         cmdthread.start()     end sub      private sub cmdautomate()          dim myprocess new process         dim startinfo new system.diagnostics.processstartinfo          'starts cmd prompt         startinfo.filename = "cmd.exe"         startinfo.redirectstandardinput = true         startinfo.redirectstandardoutput = true          'required redirect         startinfo.useshellexecute = false          'disables creation of cmd prompt outside application.         startinfo.createnowindow = true           myprocess.startinfo = startinfo         myprocess.start()         dim sr system.io.streamreader = myprocess.standardoutput         dim sw system.io.streamwriter = myprocess.standardinput          'runs command entered...         sw.writeline(textbox1.text)          'exits cmd prompt          sw.writeline("exit")          'displayes results...         results = sr.readtoend         sw.close()         sr.close()          'invokes finished delegate, updates textbox results text         invoke(finished)     end sub end class

for example when use command fastboot @ cmd 

usage: fastboot [ <option> ] <command>  commands:   update <filename>                        reflash device update.zip   flashall                                 flash boot + recovery + system   flash <partition> [ <filename> ]         write file flash partition   erase <partition>                        erase flash partition   format <partition>                       format flash partition   getvar <variable>                        display bootloader variable   boot <kernel> [ <ramdisk> ]              download , boot kernel   flash:raw boot <kernel> [ <ramdisk> ]    create bootimage , flash   devices                                  list connected devices   continue                                 continue autoboot   reboot                                   reboot device   reboot-bootloader                        reboot device bootloader                                       show message  options:   -w                                       erase userdata , cache (and format                                            if supported partition type)   -u                                       not first erase partition before                                            formatting   -s <specific device>                     specify device serial number                                            or path device port   -l                                       "devices", lists device paths   -p <product>                             specify product name   -c <cmdline>                             override kernel commandline   -i <vendor id>                           specify custom usb vendor id   -b <base_addr>                           specify custom kernel base   address   -n <page size>                           specify nand page size.   default: 2048   -s <size>[k|m|g]                         automatically sparse files greater th                                            size.  0 disable

but when use program 

microsoft windows [version 6.1.7600] copyright (c) 2009 microsoft corporation. tous droits r‚serv‚s.  c:\users\badro@istambul\documents\visual studio 2010\projects\windowsapplication1\windowsapplication1\bin\debug>fastboot   c:\users\badro@istambul\documents\visual studio 2010\projects\windowsapplication1\windowsapplication1\bin\debug>exit

the syntax output fastboot.exe when ran without arguments displayed through error stream; use redirectstandarderror capture this;

startinfo.redirectstandarderror = true dim se system.io.streamreader = myprocess.standarderror

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
