c# - Cannot Write to the Registry under HKEY_LOCAL_MACHINE\Software -

-

i'm writing application needs create special user account hidden login screens , control panel users applet. writing dword value of 0 user name registry key below, i'm able accomplish goal:

hkey_local_machine\software\microsoft\windows nt\currentversion\winlogon\specialaccounts\userlist

the problem under windows 7 uac on, no matter try, cannot programmatically write value key above.

it understanding writing keys not allowed on windows 7 uac on, unless running administrative privileges. i've added application manifest requestedexecutionlevel level="requireadministrator" uiaccess="false", accept uac prompt when program run, account member of administrators, yet still unable write above registry key.

what more need do? how possible, in application configuration, write keys , values under hkey_local_machine\software?

further information ... when program runs, no errors thrown , seems write values. guess windows virtualizing location writing. need write actual location, not virtual one, if hide special user account.

probably program runs 32-bit program on 64-bit operation system? in case recommend search values created under wow6432node subkey of hkey_local_machine\software.

you can read more such kind of virtualization here. can use key_wow64_32key flag in api able work full registry without virtualization.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
