thanks for the reply. The problem is that the BeginStoryboard is in a Trigger, which is far nested into a DataTemplate so I cannot give it a key. I got to the BeginStoryboard through code by navigating through the template and registering everything that I need. So when I finally call story.Storyboard.Begin(this); I get no errors, the code is run (checked via tracing through it) but the animation doesn't happen. Any reason for this? Wrong containingObject? rather have something you don't need, than need something you don't have

Another issue is newbies who learn the lazy way and never learn the "better" way, and therefore wind up giving more access to their classes because they don't know any better.

OK, about no vendor. I am not familiar with WPF, ButtonChrome and such. But my basic question remains: I assume your touchscreen generates some events when touched/dragged/etc., can't you just turn these into the regular Windows commands and inject them with SendMessage or something similar (or are these all gone in WPF ?) ? In Win32 and everything before WPF (and maybe, not sure, also in WPF) events get sent to a Window, and if necessary that window will forward the events to its controls, so you typically never have to "dispatch" them yourself. Turning your touchscreen events in mouse events should give you the same thing. I suggest you have a look at the old mouse_event function, and the recent SendInput function. That is the way I would investigate. If that makes things easier, you could do first experiments on a regular PC, just turn some keyboard actions into mouse actions with one of the functions I mentioned; then substitute the touchscreen for those keyboard events.

ah,great quote! no i'm not having trouble with the code.i just feel the touchframework and touchcanvas code can be improved,it all just feels so innefficient. i want to find the code issues at the beginning of the project,rather than the end. rather have something you don't need, than need something you don't have

thanks to both of you, seems both solutions would be able to solve my problem! thanks again donovan rather have something you don't need, than need something you don't have

In C#, multiple inheritance is not an option, you may only inherit from one base class. If you are not satisfied with the "interface" approach, then you might consider extending one class and creating a member of the new class of the type implemented by your second class. That way, you'll be able to benefit from the methods of the second class. SkyWalker

NP :) Here's the code for singletons I personally use in C#: http://www.codeproject.com/cs/design/GenericSingletonPattern.asp[^] I've found it does eveything I want it to most of the time.

Hi, if your app is basically a C# program that calls a C++ dll, and that dll needs to call back some method in the C# exe, then AFAIK you need to pass a delegate and use it as a function pointer (or whatever it is called nowadays) in the C++ part. Since the delegate type must be known to both the exe and the dll, it seems it must be defined in the dll (again I dont know the details). A more general approach would be to create an additional dll that holds the C# code that is needed by both the C# main part and the C++ dll. Doing so allows the C++ project (and the main C# part) to add a reference to the new C# dll. :) Luc Pattyn [My Articles]

thanks a lot, it is working 100% now. i might have referenced an older version of the dll somehow, and after a simple clean solution for the c++ dll and c# project made it work. thanks again rather have something you don't need, than need something you don't have

silverlight is WPF/E, right ? So, it's a framework on top of C#. Silverlight is a cut down version of WPF, WPF writes complete apps. I can't see how it could be more than trivial to create an app that is a viewer, even if it's just a web browser control.
