After constructing an UI for an app, I need to access certain files that I include with the app to perform calculations for a prediction system. I'm working with Visual Studio (VS) Community and the associated Java Script that is part of the Cordova JS tools for VS. I have tried numerous codes to implement an asynchronous fileReader for text file with several hundred lines. In everything I have tried, the fileReader apparently cannot "find" the file. I have tried this in VS using Windows Phone and Android phone emulators. And I keep getting no file found. The Android Ripple Nexus (Galaxy) html and JS codes are below. Note that there is an href="OAHULONLAT.txt" in the html code, this being the text file I want to read into memory in order to perform some calculations. The JS code is a simple example, although I've tried many more complex fileReader codes. When the Android (or windows) emulator executes, I get the console.log of "no file" (the FileNotFoundException catch). But when I click on the html "Generate you Prediction" line, the file pops right up on the emulator. Can someone help me to get the fileReader to see, open, and read the file?

I have two independent VC2013 projects.
One project is for making a Lib file that I downloaded from internet. I already made the Lib file (Release, 64bits) from that project.
The other project made by my self in Release and 64bits, tries to link to the above library file.
Now, I could not because a lot of link to that library because the project properties are different.
How can I synchronize the project setting so that my project can link the library file?
Thank you very much for your help.
Hello everyone,
I am using Microsoft Visual studio 2013 Ultimate for a while now, but recently I am having trouble to create a project.
When I want to create a project, I can select the template, but when create the project, the "create project"-dialog appears, it runs for a while, but then visual studio crashes and I have to close it by killing the process.
However, I can see the solution in my file explorer, with the project in the same folder, but the project is not recognized by the solution when I open the solution in Visual Studio.
Is someone having the same problem, or does someone know how to solve this problem. Now I am solving it by force-closing Visual studio when it crashes, then opening the solution and creating a new project in the solution, but that is not a good or fast way of working, and I am getting really tired of it.
Hi,
i am becoming a bit desperate about a problem i am facing with Visual Studio 2013 Express w/ Update 4.
I wanted to start porting my Windows Phone 8 apps/games to Windows Phone 8.1/Windows 8.1 so i installed Visual Studio 2013, however, and whatever i do, the designer is not loading and show only this error message:
-
System.Runtime.Remoting.RemotingException
[4536] Designer process terminated unexpectedly!
-
I tried updating everything, including my display driver, but nothing. I tried starting a completly new project to see if something different happen, but no!
My development computer is a Surface Pro 1, used as a desktop replacement, plugged into a Toshiba Dynadock u3.0 with Dual screen using a DisplayLink.
Thanks in advance!
Hi,
I have recently started working on Windows Phone 8.1.
Installed windows 8.1 on my PC and also Visual Studio 2013 Premium Trail (it comes with windows phone 8.1 sdk).
I am facing a weird problem with my Visual Studio.
Initially when i installed i was able to see Universal Apps, Windows Apps & Windows Phone Apps under the Store Apps template.
I had also created a project for Blank App (Windows Phone Apps).
Now after few days my templates have changed and i am not able to find both Universal Apps and Windows Apps under Store Apps. Also, under Windows Phone Apps, i am not finding any template without Silverlight .
I have tried re-installing Visual Studio 2013, Updating Visual Studio 2013, installed Windows Phone 8.1 SDK and also Updating my Windows 8.1 OS.
I have also tried deleting ItemTemplateCache and ProjectTemplateCache folder and re-installed the templates using
devenv /InstallVSTemplates
devenv /Setup
Same installer on other desktops are working fine.
Every time i run the VS 2013 installer, the features list check boxes for Tools for Maintaining Store Apps for Windows 8 and Windows Phone 8.0 SDK is unchecked.
Request suggestion on the same.
Thanks in Advance

Hi,
I would like to build an application that runs the same ASP.NET version that was shipped with VS2010 (I think it's ASP.NET 4, .NET framework version 4). Will installing VS 2013 Community and selecting .NET framework 4 as target environment allow me to do so?
That is, can you use the latest VS, just changing the .NET framework version when creating projects, so that you can develop and run and applications with a previous ASP.NET version but having the latest tools, source code editing features, etc.? Is there anything I should be aware of before starting the development process? (Such as updating some properties before deploying the application, needing something on the server...)
Knowing the pros/cons will help me to chose the right VS version and avoid future problems.
(I have no experience on web development or targeting previous versions of .NET, forgive me if it's an obvious question :)).
Thanks
I've recently converted my solutions to 2012. On a whole it's okay, however one problem/change is really bad and I hope there is a fix or workaround. I publish to servers using FTP Publish. In 2010 if the 'delete' option was not checked Publish would sensibly only update the files that had changed.
However now with 2012 it is updating every file on every publish. As you can imaging a site with a large bin & image directory that this take a long time. Not everyone has the luxury of being connected to a T1 network with MB+ upload speeds.
Please tell me there is some config setting to turn off upload every file.
Hi,
I've read the Community Edition's license terms, and as my company doesn't qualify as an enterprise (<250PCs, and definitely < $1MM) and there'll be less than 5 people working on it, we want to use VS 2013 community edition instead of the Web express edition.
We'll be selling the application to one of our customers, but I understand with our small team this is allowed. I think we can even complete this with the 5 basic users of visual studio online and have an exciting development pack. Is that right?
Thanks in advance
Hi,
I'm about to embark on a project which will end with a website that gathers users info (name, email, description, youtube address etc), then will display that info to other users via filtering.
My initial instinct is to create an empty website, then create a standard membership site with a database (See here) then to add a few tables that will allow me to gather the extra data.
Should I:
Or something else completely?
(ps, When I click on online templates I get 'No Items Found'
Thanks

I have restarted, turned off, updated the computer, waited some days and nothing.
I have removed temp files
I have checked privileges of Program Files and Program FIles (x86)
I have removed the "shadow cache"
I have created a new blank project and same exception in the xaml designer
I have executed devenv /installvstemplates
I have used repair installation of Visual Studio 2013
I have installed Visual Studio 2015 Technical Preview and same exception
Any idea?
Thank you.
For some reason, when one of my students double-clicks on an object and goes into the code window, the student sees the code that creates the form and objects. Most students see only the code they create (the Public Class Form1, End Class, and the click event procedure header and End Sub). I've not found a way to "hide" the code that VS creates when the form and objects are created. Does anyone know how to "hide" that code?
Thank you.
I am running Visual Studio 2012
I am getting a return code of 0x80070091. This happens when I do a Build 'Deploy Solution'.
Visual Studio 2012 worked, until I did a Visual Studio download Visual Studio 2013.
Hi!
I am attempting to create a program that converts speech to text when you click a picture, but it always crashes at the last line. Can somebody help me with this? Here's the code. Thanks in advance!
Private Sub PictureBox14_Click(sender As Object, e As EventArgs) Handles PictureBox14.Click
Dim engine As New Speech.Recognition.SpeechRecognitionEngine
Dim dictionGrammar As New Speech.Recognition.DictationGrammar
Dim recognitionResult As Speech.Recognition.RecognitionResult
Dim timeSpan As New TimeSpan(0, 0, 10)
engine.SetInputToDefaultAudioDevice()
engine.LoadGrammar(dictionGrammar)
recognitionResult = engine.Recognize(timeSpan)
TextBox1.Text = recognitionResult.ToString
End Sub
The toolbox is empty.
If I click Show All the items appear, but are greyed out and cannot be used.
Reset toolbox changes nothing.
Choose Items shows the components that should be in the toolbox all checked. Have reset from the Choose Toolbox Items window without any change as well.
I have tried using devenv /Safemode with no change.
I read that I could try removing the .tdb files, but I cannot find them in a search and the path used in the examples I cannot find in my windows explorer.
I am using Windows 7 64bit
Any help anyone can give me would be appreciated
Hello,
Can somebody please explain "Add Reference in Solution Explorer " concepts ?? IF I browse and add a .dll will it be bundled with the .exe automatically or need to provide the referred dll-file separately ??
Thanks in advance ..
Hi,
I'm trying to add reference to an external dll into my VB project ("Project>Add Reference" in Visual Studio 2013 Community) and get the "...please make sure that the file is accessible and that it is a valid assembly or com component".
I already successfully added several other dll from the same manufacturer into my project but can't figure out why some of them give me that message and fail to be added.
I tried using Tlbimp to modify the DLL but the modified DLL, created by Tlbimp, still refuses to be added
Is there a way around this? Another way to import that DLL?
Thanks.
Hi All,
I have a requirement where I am suppose to read around 100 text files.Each file has around 10000000 records. I need to read these files and calculate average of each text file. Right now, it takes around 2 minute to do so.This is performance specific application so I need to do this in a second or less.Any help appreciated.
I am using C# for this. Total data from all the files would be around 6GB.
