半城伤御伤魂 提交于 2021-01-18 04:34:14
问题 i am writing a code which try to collect information about system-process performance. I have some counters like %Cpu, RAM, etc. but i am not able to get info about handles (like Process Explorer does). To get handles count of a process we can use GetProcessHandleCount() but i need "something" that tells the global count of handles used in the computer and the type of those handles(File, Key, Event, Directory, etc) Does anybody know if there is some function that get that information? Thanks

问题 I have an android application which lists installed and system applications separately. When the user tries to reboot the device from my application it will open my application instead of default home launcher. But when the device is rebooted to 'safe mode' all logic crashes .ie, the device rebooted to my application in safe mode but it does not list any installed applications and stops its working. Is it possible to make my application work in 'Safe mode' also? Is there any way to prevent

Bloc: is it possible to yield 2 time the same state?

久未见 提交于 2020-05-17 08:40:45
问题 In the login view, if the user taps on the login button without having inserted his credentials, the LoginFailState is yield and the view reacts to it. If he taps again, this LoginFailstate is yield again, but the view doesn't react to it. So, is there a way to yield more times the same state? There is some code to better explain my situation: class LoginBloc extends Bloc<LoginEvent, LoginState> { @override LoginState get initialState => LoginUninitialized(); @override Stream<LoginState>

Comparing filehandle with glob returned by IO::Select::can_read()

半世苍凉 提交于 2020-04-13 20:41:09
问题 I am trying to manage three filehandles via IO::Select in perl. I have 1 input handle, 1 input/output handle, and 1 output handle. Im having a little trouble determining which filehandle is which when processing Select's return arrays of can_read() and can_write(); Example below Any advice on how to actually compare these two filehandles? I've tried scalars, i've tried references, no references, etc. I can't think of why this isn't working. #!/usr/bin/perl use strict; use warnings; use IO:

Delphi Application.CreateForm is the Handle Unique for each Form?

廉价感情. 提交于 2020-01-25 09:13:11
问题 I have a TreeList , with many Items , each item has it's own unique ID . I allow the user to open multiple IDs at once . But I would like to prevent the user from opening the same ID twice . So I thought about creating a simple Dynamic Array where I store which TreeList ID is connected to which Form HWND . If I find a ID on my list with a Matching HWND, then I simply bring the Form which is already Created to Foreground. Application.CreateForm(TChapter, Chapter); Chapter.PopupParent:=Main;

问题 This question already has an answer here : Matlab - Handle object properties of unique objects refer to the same object? (1 answer) Closed 3 months ago . I am trying to used updatable object (class) in Matlab with nested class. I observe a behavior that seems to be due to the handle status. I write the 2 classes testA and testB . testB is a the main class that calls the class testA as a property: classdef testB properties objA=testA; end methods function obj=testB() obj.objA if isempty(obj

wxPython won't close Frame with a parent who is a window handle

巧了我就是萌 提交于 2020-01-23 17:59:10
问题 I have a program in Python that gets a window handle via COM from another program (think of the Python program as an addin) I set this window to be the main Python frame's parent so that if the other program minimizes, the python frame will too. The problem is when I go to exit, and try to close or destroy the main frame, the frame.close never completes it's execution (although it does disappear) and the other program refuses to close unless killed with TaskManager. Here are roughly the steps

Get function handle of fit function in matlab and assign fit parameters

夙愿已清 提交于 2020-01-23 14:02:28
问题 I'm fitting custom functions to my data. After obtaining the fit I would like to get something like a function handle of my fit function including the parameters set to the ones found by the fit. I know I can get the model with formula(fit) and I can get the parameters with coeffvalues(fit) but is there any easy way to combine the two in one step? 回答1: This little loop will do the trick: x = (1:100).'; %' y = 1*x.^5 + 2*x.^4 + 3*x.^3 + 4*x.^2 + 5*x + 6; fitobject = fit(x,y,'poly5'); cvalues =
