由 别来无恙 提交于 2019-12-12 02:57:42
问题 I am talking about making a widget which extends a child widget of WP_Widget. Using this as reference: https://wordpress.stackexchange.com/questions/101438/how-to-extend-a-wp-widget-twice Example: My_WidgetBase extends WP_Widget My_Widget extends My_WidgetBase I want to know how to get My_Widget to show up with my other widgets (it is not currently). I have gotten My_WidgetBase to work. This is important for my framework. I understand that widget(), update(), and form() must be overridden,

问题 I tested code like this: class A { public A() { } public virtual void Test () { Console.WriteLine("I am A!"); } } class B : A { public B() { } public override void Test() { Console.WriteLine("I am B!"); base.Test(); } } class C : B { public C() { } public override void Test() { Console.WriteLine("I am C!"); base.base.test(); //I want to display here "I am A" } } And tried to call from C method Test of A class (grandparent's method). But It doesn't work. Please, tell me a way to call a

How should I clean up hung grandchild processes when an alarm trips in Perl?

问题 I have a parallelized automation script which needs to call many other scripts, some of which hang because they (incorrectly) wait for standard input or wait around for various other things that aren't going to happen. That's not a big deal because I catch those with alarm. The trick is to shut down those hung grandchild processes when the child shuts down. I thought various incantations of SIGCHLD , waiting, and process groups could do the trick, but they all block and the grandchildren aren

问题 I have an association as so: User has many Uploads Uploads belongs to User and has many Upload Images Upload Images belong to uploads <-- Grandchild I create my User before I add Uploads to that User. Uploads are stand-alone files of misc type, but they can also have many Upload Images linked to them to better describe the Upload (hence the seperate Upload Image model). Right now the Upload and Upload_Image persistence takes place in the users update function as they're nested form attributes

Microsoft Access runtime error 2455 when trying to access grandchildren forms from child form

由 ▼魔方 西西 提交于 2019-12-01 21:27:49
问题 I have three forms in an Access 2003 database (developing in Access 2007) that sit in a parent -> child -> grandchild relationship. In the 'Form_Load' sub of the child form, I set some properties of the grandchild (form header, row source, and control logic). When I view the child form, everything works properly. When I view the parent form, I get the error: Run-time error '2455': You entered an expression that has an invalid reference to the property Form/Report. in reference to the line: Me

Regarding background processes using fork() and child processes in my dummy shell

由 家住魔仙堡 提交于 2019-11-30 06:25:10
问题 I'm trying to create a simple shell program in C. What I need it to do is provide the user with a prompt in which they can run other local programs. I can do that part fine, using a fork() in which the parent process waits() on the child,and the child execvp()'s the program. However, if the '&' character is appended to the end of the user's command, I need their program to run in the background, meaning I need the parent to NOT wait on the child process but instead immediately return the

How to call super method from grandchild class?

由 非 Y 不嫁゛ 提交于 2019-11-27 21:49:42
I am working with some code that has 3 levels of class inheritance. From the lowest level derived class, what is the syntax for calling a method 2 levels up the hierarchy, e.g. a super.super call? The "middle" class does not implement the method I need to call. Well, this is one way of doing it: class Grandparent(object): def my_method(self): print "Grandparent" class Parent(Grandparent): def my_method(self): print "Parent" class Child(Parent): def my_method(self): print "Hello Grandparent" Grandparent.my_method(self) Maybe not what you want, but it's the best python has unless I'm mistaken.
