How to make a start tile reference the desktop AND modern mode of an app?

I've made an app for the Windows desktop and also created it for the modern (metro) interface in Windows 8.1. I wanted to group them under the same start tile and have a setting that allowed the user to open the app in the chosen mode by clicking the start tile. I got this idea from Chrome, which has both modes referenced by the same tile in the start menu or the link on the taskbar. I thought that maybe when the setting was changed I would delete the current one and replace it with one that referenced the other mode, but positioning is a problem, as a new tile always appears at the far right of the start screen. How would I resize the tile correctly and how would I delete and replace a link on the taskbar? I am using VB right now, but I can write C# and C++ so feel free to post code or links to code that are written in these languages.
If you have any suggestions, please post a reply or a ask a question in the comments.
I also should note that I prefer to use native libraries only and do not like using third-party dlls.
Thanks in advance for the help.
P.S. I've already tried Google.

I've figured it out!
The best way to do this is to create two registry keys referencing the two interfaces but make both the desktop and modern version not have a start tile! Then create a third app that has a tile and make it open the files, check for the active interface, and send the data to that interface with the file as a param.
Thanks for everyone's help, though :)

Create an editable table using WPF controls

Maybe this is not the right forum for my question, but I'll try anyway.
I am creating an application where I want the user to be able to fill in values in a table/matrix. The values are then going to be saved to a database I have set up. I want to build this application using Windows Presentation Foundation (WPF). I watched the following video on youtube:
https://www.youtube.com/watch?v=_i4mYXSaD4w and it shows very well what features I want my own application to have. The problem is, the example in the video is made in Winforms...
So, my question, which can be split into three parts, is:
Is there a way to build something equal, similar or better, in WPF?
What/which control(s) should I use? Grid? DataGrid?
How do I use this control?
I am new to WPF, and do not have a good picture of what controls to use. I have read many questions about WPF's DataGrid on StackOverflow as well as other QnA's, but I couldn't understand how to do what I wanted, or even if it was possible. Therefore, I'm very thankful to anyone who can explain and lead me onto the right track.

I suggest you to read this article: http://www.codeproject.com/Articles/30905/WPF-DataGrid-Practical-Examples

object traking within a video file

I have an intresting project assigned to me , and I would like if you can provide me with an idea of what I should look for and read and learn.
(Im not asking for solutions )
I have to make a windows application using C# that have an option to load a video file (avi or any) and then the application detect a specific color or an object such as a ball or a face or whatever.
I heard there is a library called opencv and Im learning a lot from it .
I would like to learn more and more , but I want to avoid wasting my time on somthing old or not applicable.
please advice
thank you

Have you tried Googling first? The 3rd result from searching opencv track is this fantastic post:
Tracking colored objects in OpenCV
If you’re new to image processing, you’ll enjoy this project. What we’ll attempt to achieve in this tutorial is tracking the location of a coloured object in an image. In our case, it’ll be a yellow colored ball.

Image gallery swipe UI in MonoTouch

I am looking to create a UI experience almost identical to swiping through images in the Camera Roll on the iPhone. I have 5 images that I simply want to be able to swipe through. This view will be the first view of a Tab Bar Controller that I have in place. This is my first iPhone (iOS) app attempt so if anyone feels this question needs to be broken down into smaller chunks, please let me know.

Here's an example of the paging control for MonoTouch I developed some time ago: https://github.com/escoz/monotouch-controls
Take a look at the PagedViewController. That code is actually used in my app, Quicklytics.

Use Pagecontroller.
In this example they have add label, instead of that you add your imageView.
EDIT:
For Monotouch.

The Photos module of Nimbus is exactly what you are looking for.

The MonoTouch bindings can be found here.

c# Tree/MindMap GUI

i am trying to research some gui technology for c# where i can display a tree view (opposed to the standard one provided.)
Essentially i want to have the gui draw a tree of data (as if you were going to draw a binary tree on a piece of paper or something) Then making each of the nodes clickable.
If this isnt available does anyone know of something where i could have a mindmap type GUI which shows links between elements and those are clickable?
I can guess people will say make one yourself, in which case i give up already ;) thats too advanced for me and as i am on a work placement i dont think i would be granted the time to make it as there are more pressing issues to get working first, like actually making the programme work!
Thank you

You can take a look at the controls in Kevin's WPF Bag-o-Tricks which has a WPF mind map style layout. Here is a nice example. If you want to use more professional components take a look at the product from Nevron Software, they have some great controls. There is also an opensource WPF graphing library - graphsharp (which I have no experience with, but I found a nice article by Sacha Barber). Since it's used in nDepend it must be pretty mature.
I hope you get some inspiration from those links :)

I also found XMind API for C#
https://xmindapi.codeplex.com/
It's free and looks easy to use.
