a network volume's name can changed.

to change network name, do

  • write new name in registry.
  • attach network volume using functions definedosdevicew. in timing, windows explorer read registry in guessing.
  • shchangenotify(shcne_driveadd, shcnf_path, root, null); // sure.
  • sendmessagetimeout(hwnd_broadcast, wm_devicechange, message, (lparam)(&dbv), - smto_abortifhung, 200, &dwresult); // sure again!

it works, doesn't work though use shchangenotify , wm_devicechange sure. sometimes, new name not applied in windows explorer.
if terminate explorer , re-execute, name applied.

i'm finding interface having windows explorer refreshed.(is correct syntax? sorry, can't express sentence well.)
there proper function? explorer should re-read registry , refreshed.

unfortunately, explorer can't refresh every time told so. because way many apps behave badly, , use shchangenotify() shcne_allevents. imagine if explorer refresh every time receives notification (yes, several times per second!).

that's why doesn't work.

but here's how can 'trick' explorer: send notification more 1 path, bottom up. it's enough first send notification e.g. n:\folder , n:\ refresh n:\.

and should send wm_devicechange message first, call shchangenotify().

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....
