parent-child

What is the preferred method for creating children objects? Adding the child to a collection on it's parent and calling update on the parent, or Creating the child explicitly, add the child to a collection on the parent, and updating the parent? I'm struggling with #1. And it's hard enough that I'm thinking #2 is preferable (less "magic"). Radim Köhler Not sure what would be the "preferred method" (it could depend on who does prefer) . But I can share my way If the parent is a root entity, then we should save all the reference tree in in one shot: session.SaveOrUpdate(parent) . E.g. Employee

I am pretty new to the WinApi calls although familiar with VBA. What I am trying to do is to hook to a child class SysTreeView32 of VBE window (Project Explorer TreeView). I would like to expand/collapse the tree view elements by modifying the registry keys (or alternatively sending the mouse clicks (mouse_event) although I prefer the first option). I can find the Excel Main Window by using this code: Declare Function FindWindow Lib "user32" Alias "FindWindowA" _ (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Sub Find_Window() Dim hWndExcel As Long hWndExcel = FindWindow(

I have a non-modal child form which opens up from a parent form. I need to center the child form to its parent form. I have set property of child form to CenterParent and tried this: Form2 f = new Form2(); f.Show(this); but to no avail. This works with modal form, but not so with non-modal forms. Any simple solution, or need I go through all that mathematical calculation to fix its position to center? I'm afraid StartPosition.CenterParent is only good for modal dialogs ( .ShowDialog ). You'll have to set the location manually as such: Form f2 = new Form(); f2.StartPosition = FormStartPosition

I have this jQuery: $(this).parent().parent().find(".license_tooltip").stop(true, true).fadeIn(200); The $(this) object is nested within two div s like this: <div> <div> <a href="">$(this) object</a> </div> <div> <a href="">object to fade in</a> </div> </div> Can someone point me in the right direction to making my jQuery more streamlined? The structure presented above is replicated multiple times, so using classes and IDs is impossible. You can use a class (or any other selectable attribute) and .closest() to claim to the parent you want, like this: <div class="container"> <div> <a href="">$

How would I go about starting a new process without it being the child of the calling process. Example: Main Program (Caller.exe) process.start("file.exe") Image: Josh If the spawning process (parent) ends before the spawned process (child) does, then the parent-child chain is broken. To make use of this, you'd have to use an intermediate stub-process like so: Caller.exe → Stub.exe → File.exe. Here Stub.exe is simple launcher program that ends just after starting File.exe. If you start a process, then you'll be its parent. Maybe you could try to start your process from cmd.exe instead, so cmd

I'm having trouble overcoming an issue with react router. The scenario is that i need to pass children routes a set of props from a state parent component and route. what i would like to do is pass childRouteA its propsA , and pass childRouteB its propsB . However, the only way i can figure out how to do this is to pass RouteHandler both propsA and propsB which means every child route gets every child prop regardless of whether its relevant. this isnt a blocking issue at the moment, but i can see a time when i'd be using the two of the same component which means that keys on propA will

I have this problem for a long time now, I have searched the web and SO in and out and didn't find a solution yet. I hope you can help me on that. I have a parent-child relationship between two entities like the following: @Entity public class Parent { // ... @OneToMany(mappedBy = "parent", fetch = FetchType.LAZY, cascade = CascadeType.REMOVE) private Set<Child> children = new HashSet<Child>(); // ... } @Entity public class Child { // ... @ManyToOne(fetch = FetchType.LAZY) private Parent parent; // ... } The thing is that when I create a new child and assign it to a parent, the parent doesn't
