php - Show warning/error to user without using wp_die -

-

I'm currently developing a WordPress plugin to work for my plugin, I need some information on settings information is.

  1. Is there a way to throw a warning / error that the blog administrator can see his message on his dashboard?
  2. Is there any other way to show errors other than wp_die ()? Just in case of my plugins (or someone else's) screws and I want to inform that in a fashion well;)

I would recommend using the admin_notices operation to allow you to display warnings and errors and to direct your users to a page: 

  Add_action ('admin_notices', 'my_custom_warning'); Function my_custom_warning () {if (true == true) {echo '& lt; Div id = "my-custom-warning" class = "error fade" & gt; & Lt; P & gt; This is a test & lt; / P & gt; & Lt; / Div & gt; '; }}

This method ensures that your users can still use WordPress but they will tell them where they can get a potential problem. Html

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
