Denial of permission while deleting SQL Server 2005 Express database file on Vista -

-

i using ms sql server 2005 dbms winforms app. data stored in encrypted archives containing .mdf , .log files. app running admin rights.

while app using given data file, .mdf , .ldf files extracted users temp folder , attached dbms. when file closed app menu, db detached , db files archived original archive file, , deleted users temp storage.

everything has been working fine on win7, xp , vista machines. on of clients vista machines denial of access errors logged, while app moving detached .mdf , .ldf files archive them. @ same time there no such errors on other machines, having same os (vista) , antivirus (avast)

the main things check are:

  • be sure have admin rights. if pcs on different domain, check "administrator" gives rights think you'll get.
  • sql server may still have database files open. may simple waiting few seconds after dismounting sure it's finished before start working on database files.

a better approach may ask sql server handle databases you: restore/backup database from/to archive , drop using sql calls, rather trying modify raw files yourself.

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....
