c# - Showing Difference between two datetime values in hours -

-

i retrieving 2 date time values database. once value retrieved, need difference between 2 values. that, create timespan variable store difference of 2 date values.

timespan? variable = datevalue1 - datevalue2;

now need show difference stored in timespan variable in terms of number of hours. referred timespan.totalhours couldn't apply same reason. how do that? using c# on mvc project. simple need show difference value in hours?

edit: since timespan nullable, couldn't use total hours property. can use doing timespanval.value.totalhours;

i think you're confused because haven't declared timespan you've declared timespan? nullable timespan. either remove question mark if don't need nullable or use variable.value.totalhours.

delphi - TJvHidDeviceController "DevicePath" always showing "\" -

i'm using tjvhiddevicecontroller class retrive hid device information. have plugged 2 hid devices, i'm trying ge "devicepath" of sp_device_interface_detail_data_a structure getting device path '\'. ican't open createfile function. please me solve issue. os win7. all. this guessing! the 1 thing can think of is: tjvhiddevicecontroller calls windows api call without using or w suffix. structure used sp_device_interface_detail_data_a, ansi version. now, if use delphi 2009 or higher, routine expect sp_device_interface_detail_data_w. size same looks ok. strings stored usc2 encoded (widechars) instead of ansi encoded -> after every ansi character there null byte. tjvhiddevicecontroller converts character array pascal string using function strpas , hence, see first character. check: set breakpoint after function call fills structure , use cpu window view content memory dump. if see ansi characters every other byte , null bytes in between, ca...

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,...
