BackButton Windows Phone 8 (VB) - vb.net

I have a Program with 2 Frames ("MainPage" and "Inicio", "Inicio" is the first one on be opened).
"Inicio" Has a Link to open "MainPage" and, when the user is on "MainPage", I want to make an event that when the BackButton (the <- of the phone) is pressed, the Program go back to "Inicio", but instead of it, the program is suspended and the Phone go back to the Windows Home.
I'm working on VB and I can't find any tutorial or Event to VB, all that I found on google was to C# and I don't know how to convert code from C# to VB for now.
Please Note that I'm working with VB for Metro (Or VB For App Store) and I had to define the event on the XAML, and there is the problem, because, not like when we code on .VB, I don't have suggestion or error marks. I can write "aigwiuagwa_aiuwdaiu as Handler..." and for the builder that Event exists.

The problem is that I was ussing "Blank Page", and I needed to use "Normal Page". "Normal Page" has Navigation Helper that detects if there is another Page/Frame to go back or not. Another thing is that NavigationHelper has a lot of "#IF WINDOWS_PHONE_APP Then" and it doesn't detects that it is actually an Windows Phone Apps, so the Back Button doesn't works either. The solution was to Delete that IF, and below of then is allways an "ElseIf", the thing is to replace that "ElseIf" with "#IF WINDOWS_APP then". I needed to do it 3 times. Now my app is working fine.

Adding GroupBox into VB program causes the program to crash

So here's a head scratcher. Recently I finished a program in VB that have several GroupBox to place my buttons in. And during testing in my PC everything worked out fine.
But when I want to test it on user PC, the program immediately pop up a "The program is not responding" message and stops process immediately without even showing the form. The user PC does not have Visual Basic 2010 installed.
After experimenting further I found out that the GroupBox were the cause, when I removed them the program can run in user PC fine.
So yeah... Till now I don't know why GroupBox doesn't want to play well like this. Is this a common problem in general?
P.S. I don't know if this is the right place to ask this. If not please let me know and I'll remove this question. Thanks.

VB.Net application highlights all files in background when running / getting focus

I have an App that I inherited in VB6 and have ported mostly to VB.net
When I compile / run the app - it highlights all the files in the current selected folder.
What makes it worse, is it's very difficult to search online as what search terms does one use?
The app was ported to VS 2005 - quite successfully - but this has me stumped...
I have tried commenting out all the code that's run on startup and it still does it, so it must be some sort of background thing...
Any ideas?
I can't find an old version of my app to see if it's changes I have made and I don't know where to begin. See the image:
The top part is before I run the app, the bottom is once the app is running and has focus. I hope it makes sense
Also, if I'm browsing and then run the app, and go back to the browser, when my app gets the focus again, the webpage goes back to the top...
The folder is just an example - Basically when I compile (or later run) my App, if I go to Windows Explorer - when the app gets focus - whatever folder I am in has all its files highlighted. If instead of going to Windows Explorer, I go to a web browser, when the app gets focus the browser goes to the top (similar to Home).
There is Windows Integratio, but I have commented out what I can and still am no closer.
Does this info help?
I found the problem - after going back to the vb6 project and removing everything except for the 5 modules needed to startup and I eventually tracked the problem.
There was some code being called when two edit boxes received focus which called send keys home and end - hence it would go home - select all files to the end. I had deactivated one of the edit boxes to not receive focus and it helped temporarily(obviously until the other box got focus), but since deactivating the send keys when they get focus has helped. Albeit an arbitrary problem, maybe it will help someone in the future..

No taskbar icon for application

So I have this application I have made in VB. The problem is that when I start it it does not show up in my taskbar. It only shows up if I maximize another window infront of it and then minimize it. Also it has the basic VB icon even though I changed the icon in the properties.
There is no relevant code for this issue.
I found the same thing; no icon was showing in the taskbar. I had to go into Task Manager and Switch To the program to get it to show. I could ' maximize another window in front of it and then minimize it as well.'
Found the solution that worked for me. The 'Main' form did not have anything in the 'text' property because I was doing that and a Ver number in the program. As soon as I put text into the 'text' property, it started working. The problem was only with VB2015. Worked fine in VB2010.

Why is my VB app invisible to the screen recorder?

I have written a VB application in VS2010. When I try to record its operation for a demo video with Windows Media Encoder x64 or Apowersoft free screen recorder, I get a recording of everything on the desktop except my application. It's like the application is invisible to the recorder. It has worked in the past (2 weeks ago). It must be something I have done but I'm baffled. Is there a "feature" in VB that can prevent you from recording the Form?
BTW, a still screen capture works fine and sub forms I bring up are captured. Only the main form is invisible to the recorder.
Thank you for your help and time.
Not a VS or VB problem after all. What I found was that windows 7 was switching me from Aero Theme to Windows 7 Basic. The message that showed up was that I was low on display memory. (A quick pop-up in the bottom right corner that I was ignored during the recording). However, I have 4.75 G of display memory?
BTW on a video conf call it produced the same invisibility "feature" until I found the Theme switch.
I haven't actually fixed anything but now know to watch for the tell tale screen blink as it switches mode. I pause the recording, and switch it back before restarting the recording. Got through the recordings I needed for now. I was using MS Media Encoder. I have now replaced it with Adobe Premier elements but haven't tried it yet to see if I still have the problem. Need to get the "how to" videos out the door first.
Thanks again. I have read many of your Answers to others in the past that have helped me solve numerous other VB and VS problems.

That's weird since it's recording forms from the application and not other forms (main form) from the same application.
Make sure you run the recorder as administrator and not the application.

Silverlight - Lync Application nested in a table

I'm very new in Silverlight and the Lync-SDK. So sorry for the question from a beginner.
Long time ago, i wrote al little web application, based on php for reading out contacts from a sql database.
Now the customer expand his envoirement and place Lync. Now he want the little Lync-Status-Square in the webapplication for click to call features.
I playing a little bit with the SDK of lync.
The following problem comes up. The square of Lync is nested in a td of my table. But the Lync-Silverlight-Applet need dynamical space for hover effects or single clicks. But in my table, i have no space, specially dynamic space.
So i switch off all hover and click functionality and place the follwing buttons in the StackPanel separate.
PresenceIndicator
StartInstanceMessagingButton
StartAudiCallButton
SendEmailButton
Two of them are fine.
Clicking on the IM-Button, The Lync Client opens the right Contact in IM-Mode and i can directly type a message. Perfect!
Clicking on the Mail-Icon, an Mail-Client will open, perfect.
The PresenceIndicator just display the color, not the exactly state, thats a problem, when the color is yellow. I can display the state in a TextBlock, but i prefer a label appears while hovering over the icon.
But my mainproblem is the StartAudioCallButton. This Icon is an dropDown-Icon. And i have no space for dropdowns. I would be so nice if this icon has the same behavoior like the IM-Button. The Lync Client will open in Call Modus and i can select, which callernumber i will use. Is that possible?
Thank you for Your time!

If you're having trouble with the layout of the standard Lync SilverLight controls, then the best thing to do is implement your own SilverLight controls for the function you're having difficulty with.
User Controls are really simple to create, there are plenty of tutorials on how to get started if you're not familiar with the process.
The Lync SDK has some great walkthroughs to get you up and running with signing in to Lync and placing an audio call
I don't know of any way to get Lync to open in a Call Mode as you suggested, but if you're limited with screen space, maybe you could have your custom StartAudioCallButton open a popup with the phone numbers in?
