dynamic

问题 The idea is that given a specific input to the program, somehow I want to automatically step-in through the complete program and dump its control flow along with all the data being used like classes and their variables. Is their a straightforward way to do this? Or can this be done by some scripting over gdb or does it require modification in gdb? Ok the reason for this question is because of an idea regarding a debugging tool. What it does is this. Given two different inputs to a program,

问题 I have an MVC3 site that I've setup for testing another site - most of it has been quick and dirty, and so I've not gone to town creating model and view model types for all the views - only where input is requried from the user. Okay so I have a controller method that projects a Linq sequence and sets it into ViewBag . ViewBag.SomeData = Enumerable.Range(1,10).Select(i=> new { Value = i }); In my view (Razor C#) I then want to read this - quite simple: @foreach(dynamic item in ViewBag

问题 Can we start a dynamic backend programatically? mean while when a backend is starting how can i handle the request by falling back on the application(i mean app.appspot.com). When i stop a backend manually in admin console, and send a request to it, its not starting "dynamically" 回答1: Dynamic backends come into existence when they receive a request, and are turned down when idle; they are ideal for work that is intermittent or driven by user activity. Resident backends run continuously,

问题 I am trying to figure out how to create QPushButton by pressing another QPushbutton so that I can ultimately create buttons dynamically. It seems like the initial method for creating buttons doesn't work in a function. import sys from PyQt5 import QtCore, QtWidgets from PyQt5.QtWidgets import QMainWindow, QLabel, QGridLayout, QWidget from PyQt5.QtWidgets import QPushButton from PyQt5.QtCore import QSize class MainWindow(QMainWindow): def __init__(self): QMainWindow.__init__(self) self

问题 This question already has answers here : Is it impossible to use Generics dynamically? [duplicate] (2 answers) Closed 6 years ago . I'm trying to simplify my methods in creating several variables in a function which is repeated for different types and different actions, eventually I will migrate to a single function that can handle multiple types but I'm doing it in stages. I would like to be able to make a list of objects in their types instead of List without having to copy/paste the object

问题 I've been fighting to get custom error pages to work and keep finding my way back to simply using a static page. Though the static page works, it would require remaking the navigation bar which we would like to avoid at this time. I'm currently using the following to specify custom error pages. Asp.net Error Handling <customErrors mode="On" redirectMode="ResponseRewrite"> <error statusCode="404" redirect="~/404.aspx"/> </customErrors> IIS Error Handling <httpErrors errorMode="Custom"> <remove

问题 I am trying to create the following dynamically, however I am having problems calling the extension method FirstOrDefault : using(var context = new Entities()) { var list = context.Engines.Include("Cars").Select(e => e.Cars.FirstOrDefault()).ToList(); } I have the following Expression parameter = Expression.Parameter(typeof(Engine), "e"); Expression property = Expression.Property(parameter, "Cars"); parameter = {e} property = {e.Cars} Those are good, but I am encountering a problem when I try

I tried this: queryParams: { group.name: group.items[i].param }

问题 I'm trying (without luck) to implement an "Object Dumper" for objects I'm accessing in the Office Type Library. It must be possibly, because VS's debug window has a "dynamic view" for the System.__ComObject objects that effectively does what I want. Any ideas? 回答1: I have also created a method for getting an interface that can be used for accessing the object. Use: using System.Runtime.InteropServices; using System.Runtime.InteropServices.ComTypes; You have to have an IDispatch interface in
