c# - Settings randomly not available -

-

i've started visual c#, surprising success, i've run issue, drives me crazy.

this problem applies i've tried write , i've not yet managed formulate successful google search answer question.

i use tabs form, various tabs "work" plus 1 tab contains bunch of textboxes config data, servername, logins, , on.

i've managed save settings using builtin settings feature.

now here's problem: launch application, access settings tab, enter settings, close application. when restart application previous settings retained. far good.

however, these textboxes contain correct info whenever click on settingstab, return empty string when accessed method. behaviour random, launch application, settings can accessed, close it, restart settings gone, next time they're there gone again.

but, if access settings tab, prior running method fine.

does make sense anyone? define application settings , assign them textboxes in settings tab , save them properties.settings.default.save(); when form closed. i've tried manually loading them form ie: setsqlserver.text = properties.settings.default.setsqlserver; behaviour stays same. method run, prior me clicking on settings tab, randomly receives empty string. when happens textboxes settings tab return empty strings.

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...

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 .
