Hi,
I am writing an mp3 player using wpf, I have three user controls (media
library, media controls and a playlist). Obviously I need these to
interact with each other, I assume the best way to do this is to use
events right ?.
Can I raise an event on one user control and have one of the others
suscribe to it ? or do I need to have the main window suscribe to it and
then pass the message on to the target user control ?.
Any advice appreciated.

Hello,
I am writing an mp3 player using wpf, I have three user controls
(media library, media controls and a playlist). Obviously I need
these to interact with each other, I assume the best way to do this is
to use events right ?.
I don't think the controls should be interacting with each other at all.
Besides the controls, the program should have a data model — some kind of
data structures for the media library, one section of which represents a
playlist, and the current status of the player. The controls reflect the
current state of the data model by the means of databinding, and they change
the model with databinding and commanding. They do not have to know anything
of each other, or of the window they belong to.

I have a datable in the medialibrary control that contains (amongst
other things) the path of every song. Are you suggesting I create a new
object which encapsulates the datatable as well as exposing more
properties (like the play/pause/stop status and the current song, etc.)
I guess all the controls could then just bind to relevent properties of
the object.
I have played about a bit with data binding, how do you go about binding
to an objects property ?.

Is it possible to access controls on other forms when using managed C++? In
VB, it was a simple matter of declaring the form as global, but this is
apperently not possible when using managed code.
How does one modify or read control properties when the scope of the form is
limited to the function level?
I need to have several forms open at the same time and all interacting with
each other.

I have a user control that contains 2 image buttons, when you click one of
them, both must change the image source, the thing is that the first time
you click any one of them the page appears to do a postbak, but the image
source or the image displayed does not change until I click one of the
images a second time, why dows it take 2 clicks for the user to "refresh"?
TIA!

Here is the situation. I'm developing an application where:
I have defined a class (DBClass) to provide an abstraction layer for
interacting with a database. When an instance of the class is created, it
creates a connection to the database. My initial plan was that, at the very
top of each page I would:
1) include the DBClass class file, so the page knows about the class
2) create an instance of DBClass, which I call DB.
