Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.

I'm investigating and exploring what technology to recommend for our development team's mobile application development. I have previous experience using Xamarin.Android (but not Xamarin.Forms), and my manager has previous experience with Telerik Platform (but not NativeScript).
We're looking to build fairly straight-forward apps with limited use of the device's capabilities in the future (e.g. the camera). The apps we have are currently responsive web pages but we want to start using some of the device features hence why we want to write apps.
From my own explorations thus far.
- Uses C# which we are already familiar with
- I have previous experience with Xamarin.Android
- It's part of Visual Studio
- It has great integration with the .NET ecosystem
- You need to write separate code for all device specific functionality
- You need to download and install the Windows Phone emulators to develop for the Windows Phone (which has thus far failed on my dev PC as I need to enable virtualisation in my BIOS)
- You need a Mac to develop for iOS
At the time of writing I have only managed to get a basic Android device running in the VS IDE
- One codebase for all mobile platforms
- Access to the NPM ecosystem of modules
- No support for Windows Phone (although Telerik have stated that this will be addressed in a future release)
I really like Xamarin.Forms but so far Telerik NativeScript seems easier to use with some great debugging tools and clean and consistent UI.
I've been looking into both tools over the last few days and they both have their pros and cons, so I'd appreciate any thoughts from others who may have ideas, suggestions, thoughts etc.

I select Blank App (Xamarin.Forms.Portable) and click OK. It then starts creating 4 projects.
I get prompted to connect to a Mac. No.
I get prompted for the target (Win 10 is the only choice)
I get the message "A problem was encountered creating the sub project 'App1.Windows'. This project requires a Visual Studio update to load. Right-click on the project and choose "Download Update"."
VS is still busy creating things so I can't click Download Update yet so I click OK
VS finishes creating things.
I look for "Download Updates" on the Windows project - it's not there
All 4 projects are there - PCL, Droid, iOS, and Windows. So I try to compile.
Now the fun begins. I get 37 compilation errors, all in the Android project.
OK - today isn't the best day - I'm in and out a lot - but lets see what we can do.
Where are you are the moment?
What is installed, what is working, what isn't?

I have a MC45 Motorola device an I install On it a windows mobile application with a database Microsoft SQL Server Compact 3.5, I need to view this database on this mobile device if it is possible using any tools (free or not free).
Hello guys.I recently traveled somewhere in a certain city and i discovered that their happens to be a lot of phone snatching especially to passengers in vehicles.What i discovered is that phones are snatched over the bus window without the passengers aware since most of them are busy texting on social media.
A thought came to me of whether their could be an app which detects the current user location and sends an sms alert telling him to be carefully.Like a message warning him that the location you are now entering is insecure.Please take care of your phone .This would make sure that once users get that sms they can stop for some minutes what they are doing.Imagine loosing your expensive phone ?Its so sad.Can their be such a solution?
Here was my thought.Users can mark those locations that are insecure and would save the coordinates of those areas.So once the app detects you are in a certain area which is marked unsafe in our database,then an sms can be send .My major point of concern is the workability part.
1)How can such app communicate in a real time manner considering yo have to ensure the user's battery charge is not wasted?
2)Does it mean that with such an app it needs to be on everytime checking the user location against the locations in the db?
Those are some of major points of concern am worried about.
Basically what happens is the phone snatchers knock the bus windows so fast that by the time you get to hide your phone,they have already managed to open the window and grabbed the phone.They have mastered the art of opening the windows and this happens when the passengers are stuck in a traffic jam hence becoming an opportunity for the phone snatchers.
I currently use a couple of Mobile banking apps.
Benefit - convenience e.g. being able to transfer money immediately
Risks - I'm concerned about using them except via mobile data for security reasons. In theory if I lose my phone no-one can access my bank details ... in theory!
I also use an app called Duolingo as I'm re-learning French (39 years after last studying it!).
Benefits - convenience and I get daily reminders to do my practice. I can do the practice anywhere, anytime.
Risks - not really a "risk" in the real sense but it can be buggy and the pronunciation isn't always accurate.
Benefit - easy to share photos and convenient to communicate (without talking)
Risk - it's been hacked in the past.
Benefit - keeps me up to date with the soccer scores
Risks - Depression when my team(s) keep losing
Benefit - can adjust my heating when not at home (saves money, gets house warm before I return)
Risks - none that I can think of.
There's a few others - benefits are generally convenience. I don't use unsecured apps if I need to provide any personal info.
Risk is generally that I'm never off my phone so RSI and neck aches are likely to result
Sadaf, Many thanks for your feedback. Have you ever came across anyone having issue with Banking Apps? Also we usually ignore (including myself) to read the licensing terms of these Mobile Apps. Have you ever read them? Now there has been speculation about all the data being tapped in to. Do you think if this is an issue with any of the Apps?
You have posted this 3 times so I am going to tidy up the duplicates for you. Your messages keep appearing in the moderation queue so be patient before attempting to repost.
You gave a lot more detail when you attempted to post this question as a Article - I suggest you Edit this post to add the extra detail that you had before - again be patient and wait for the site to update.
I want to read .dbf file on Network such as
Windows Mobile 5.0 Windows CE using C#
This my Code but it does not work
SqlConnection con = new SqlConnection("Data Source=//192.168.0.16/Ovnbol1000/"); // give your path directly
SqlDataAdapter da = new SqlDataAdapter("select * from KUND.DBF", con); // update this query with your table name
DataSet ds = new DataSet();
int i = ds.Tables.Rows.Count;
know I'm dumb... really... but what am I missing here - (apart form a screw or two...)
I've never developed an app for a mobile device in my life, but every time I look into it, it seems so incredibly... complicated.
Suppose I want to build a simple app that asks you to enter your name, click a button, and it will say Hello to you.
SO... my question then is: what else (avoiding sledgehammers) do I need to do to wrap this up as an open cross-platform app for smartphones? Or am I barking up the wrong tree (in the wrong forest, even)...?
Thanks again though.
