View 1 RepliesI need to produce a list of checked entries from a CheckedListBox whenever an item changes, but that ItemCheck event gets thrown before the item's status is actually changed so the checked items list is incorrect.I found a forum post telling to use the SelectedIndexChanged event instead, but that won't work if the user checks the item using the space bar.My two alternatives are to :1. Use the ItemCheckEventArgs to figure out what item changed and how. Since the code that gets the list of checked items is a few methods down on the calls hierachy, I would need to pass the event args around (or more likely an homemade representation of its data for consistency).
2. Use a class member boolean to see if I'm in the ItemCheck event handler and set the item's checked state to its correct value before calling the method that does the processing. The boolean is used to avoid an infinite call of the event handler, it would just return without any processing in the case the event handler is in the call stack itself.

I know how to handle a single objects property changed event very easily. I want to handle a objects property changed event that is part of another object.
Given Object:
[ObjectY = Y]
+ Public WithEvents X As ObjectX
I would like to do something like:
Private Sub XPropertyChanged() Handles Y.X.PropertyChanged
Right now I need to create a object that equals the object inside that object and then handle this variable pointers property changed, but that is just annoying.

1. The cmd window normally shows various status messages in colour, whereas the RichTextBox shows all messages in Black (on a white background). How can I get the RichTextBox to show the messages in the same colours that the cmd window displays?
2. As the RichTextBox fills with data, filling the box, and beyond, and the scrollbar starts to shrink, I notice that the data at the top of the RichTextBox stays there, and you would have to scroll down to see the last status message, whereas I would like it to do the reverse, i.e the last status message is at the bottom of the visible RichTextBox, and if I wanted to see the earlier messages I would have to scroll up. How can this be achieved?
