Drag Drop Operation in QTreeWidget not copying the dropped item

I want to copy an item from a QTreeWidget-parent under another parent via a drag & drop mouse operation. For this, I have implemented the dropEvent() and am setting the dropAction to Qt.CopyAction. But anyway, the item I am dropping is not being copied under the new parent. E.g. -> dragging the user "schmidt" under the group "LON". Expected behaviour: the item I am dropping is being copied under the new parent. (e.g. user "schmidt" will be added under group "LON"). Full working code example: #!/usr/bin/env python3 # coding = utf-8 import sys from PyQt5 import QtCore, QtGui, QtWidgets class

IBM MQ cmit and rollback with syncpoint

Infra-Overview: I have a setup where I am reading a set of messages from IBM MQ and processing those messages in k8 cluster env and sending it to the destination host. Issue: I observed that sometimes the flow of the messages is huge and before sending it to the destination host our pod gets failed and restarts, by this we are losing all the messages as we are following a read-and-delete approach from ibmmq example Expected Solution: I am looking for a solution where, until these messages are sent to the destination host, we don't lose the track of the messages. What I tried: We have a concept

Static member error with instance member, xUnit

"An object reference is required for the non-static field" I have a static member which cannot be an instance member. This static member uses an instance of an object that is initialized in the constructor of the class through dependency injection, so it cannot be static. How could I solve this error? public class My { private readonly Fixture _fixture; public MyClass(Fixture fixture) { _fixture = fixture; } public static IEnumerable<object[]> TestCases() { yield return new object[] { Urls.BuildUrl(_fixture.WebAppUrl)}; } [Theory] [MemberData(nameof(TestCases))] ... public static class Urls {

How to make BundleTransformer work on Windows Server Core

Ever since we found dotLess stopped working for us our ASP.NET MVC project has been using BundleTransformer for our LESS bundling and minification. We are trying to migrate our CI build agents to use Windows Server Core (headless) and away from Windows Server Standard. When we did this we started receiving Internal Server Errors when trying to hit our pages. This seems to be blowing up inside of BundleTransformer. We initially were using BundleTransformer with http://www.nuget.org/packages/JavaScriptEngineSwitcher.Msie From reading this post I thought maybe it was that we were missing the
