Reading base path from web.config

I have a web application created in MVC5/C#
The app uses jscript to call actions from a controller for certain instances. The problem I am having is that the application is nested deeper on IIS than on my local server.
Local:
var urlForModesl = "/ICS_Requisitions/Details";
IIS
var urlForModesl = "../ICS_Requisitions/Details";
Is there anyway I can grab the base path dynamically . . maybe from web.config or something? So that I don't have to keep switching back and forth. It's making testing a bit cumbersome, as there are similar situations throughout the application.

Have you tried Bundling of Js. If not follow this
// create an object of ScriptBundle and
// specify bundle name (as virtual path) as constructor parameter
ScriptBundle scriptBndl = new ScriptBundle("~/bundles/bootstrap");
//use Include() method to add all the script files with their paths
scriptBndl.Include(
"~/Scripts/bootstrap.js",
"~/Scripts/respond.js"
);
//Add the bundle into BundleCollection
bundles.Add(scriptBndl);
BundleTable.EnableOptimizations = true;

AirConsole View Manager is not defined after uploading for testing

I'm currently building a game, when I tried uploading it to AirConsole the game gives me a error in the preview.
Has anyone had this problem before?
"Uncaught ReferenceError: AirConsoleViewManager is not defined".
var airconsole = new AirConsole({ "orientation": "landscape", "device_motion": 10 });
var vm = null;
window.onload = start;
airconsole.onReady = function () {
//THE LINE UNDER CRASHES
vm = new AirConsoleViewManager(airconsole);
};
ReferenceError: AirConsoleViewManager is not defined

Thank you very much :)

I assume you got the information about AirConsoleViewManager from here (GitHub).
I can't tell for sure because you haven't linked the entire file, but you need to download the airconsole-view-manager.js and include that in your controller script.
The example from the previously linked GitHub example is kind of weird because it doesn't include the JS file in it. Most likely the reason for this is that they assume (which you should never do as a developer) people know it already.
EDIT: Actually, they do include the file but it's not done in JS file, it's in HTML file:
<script type="text/javascript" src="airconsole-view-manager.js"></script>

I do not know what the problem was, but after cleaning the build and transfering code over to another project, then uploading again it worked!

Sync to all CLs within a certain Date/Time range

My documentation and Google-fu is seriously failing me on this one, so:
how do I use P4API's GetChangelist() function to sync a range of files (i.e. all files from #now to #twoDaysAgo)? I can easily construct the command line to do this like so:
p4 changes -s submitted //...#2016/12/01,2016/12/06
but the API wants me to interface with the server via
GetChangelist(Options options, FileSpec[] files)
It's driving me crazy that I have to construct a combo of Options and Filespecs[] to make the request instead, and (AFAIK) can't just pass the actual command line string. Especially because all documentation seems to be non-existent.
Can somebody enlighten me as to what kind of filespec parameters I have to pass along? (I think that's what I need to use to specify the fact that I want to get a range of all CLs inside a certain time?) Thanks!
(As an aside: I was surprised there isn't a "P4API" tag yet, and I can't create one.)

And here's the non-command line version that you really want to use, from the Perforce documentation (once you find it :))
PathSpec path = new DepotPath("//depot/...");
DateTimeVersion lowerTimeStamp = new DateTimeVersion(new DateTime(2016,12,06));
DateTimeVersion upperTimeStamp = new DateTimeVersion(DateTime.Now);
VersionSpec version = new VersionRange(lowerTimeStamp, upperTimeStamp);
FileSpec[] fileSpecs = { new FileSpec(path, version) };
ChangesCmdOptions changeListOptions = new ChangesCmdOptions(ChangesCmdFlags.FullDescription | ChangesCmdFlags.IncludeTime, null, 0, ChangeListStatus.None, null);
IList<Changelist> changes = m_Repository.GetChangelists(changeListOptions, fileSpecs);

Alright, after a couple more hours of digging, I have found that there is a way to feed the actual command line parameters to the command. You create a DepotSpec, and then something like this is working for me to restrict the time range for CLs retrieved from the server:
ChangesCmdOptions changeListOptions = new ChangesCmdOptions(ChangesCmdFlags.FullDescription|ChangesCmdFlags.IncludeTime, null, 0, ChangeListStatus.None, null);
FileSpec[] fileSpecs = new FileSpec[1] { new FileSpec(new DepotPath("//depot/...#2016/12/05 21:57:30,#now"), null, null, null) };
IList<Changelist> changes = m_Repository.GetChangelists(changeListOptions, fileSpecs);
All this might be "indulgent smile" old news to people who've worked with the API for a while. It's just all a bit confusing to newcomers when documentation like the two pages mentioned in this post ("FileSpec object docs", "SyncFiles method docs") are offline now: Perforce Api - How to command "get revision [changelist number]"

Sharepoint - upgrade webpart properties

I'm playing with SharePoint 2010 now and have a problem.
There is a feature that is responsible for webparts - it's scope is web. It's needed to update some properties of already created webparts, for example - title.
So I've overridden FeatureUpgrading event and added custom upgrade action into feature manifest - there is no problem here.
In that feature receiver I plan to have a code that should get the file with needed page, check it out, iterate through all the web parts on it, change property and then check in page back.
The problem is that all my webparts appear as ErrorWebPart with empty title.
By the way, if I use the same code in FeatureDeactivating event - everything works good.
The only difference I've noticed - in featureupgrading HttpContext.Current was null. So I've populated it manually but it didn't help.
While googling, the only two advices were: populate HttpContext and ensure that libs with webparts are in GAC. Both conditions are done in my situation.
The sample code from FeatureUpgrading is as proper:
SPUtility.ValidateFormDigest();
web.AllowUnsafeUpdates = true;
var request = new HttpRequest("", web.Url, "");
HttpContext.Current = new HttpContext(request, new HttpResponse(new StringWriter()));
HttpContext.Current.Items["HttpHandlerSPWeb"] = web;
var fileUrl = web.Url + "/pages/sample.aspx";
var file = web.GetFile(fileUrl);
if (file.CheckOutType == SPFile.SPCheckOutType.None)
{
file.CheckOut();
}
using (var webPartsManager = file.GetLimitedWebPartManager(PersonalizationScope.Shared))
{
foreach (WebPart webPart in webPartsManager.WebParts)
{
Console.WriteLine(webPart.GetType().ToString());
}
}
file.CheckIn("System update");
Would appreciate any help. Maybe there is something I'm missing or there is another variant to accomplish described task?
Regards.

Since it is working on Deactivating(), I think the order in which the features are activated is the problem.
You may have to ensure the below:
1. First activate the Feature that adds the webparts
2. Then activate the new feature.
You can change this in package. Or better add a dependency to your new feature.

C# code completion with NRefactory 5

I just found out about NRefactory 5 and I would guess, that it is the most suitable solution for my current problem. At the moment I'm developing a little C# scripting application for which I would like to provide code completion. Until recently I've done this using the "Roslyn" project from Microsoft. But as the latest update of this project requires .Net Framework 4.5 I can't use this any more as I would like the app to run under Win XP as well. So I have to switch to another technology here.
My problem is not the compilation stuff. This can be done, with some more effort, by .Net CodeDomProvider as well. The problem ist the code completion stuff. As far as I know, NRefactory 5 provides everything that is required to provide code completion (parser, type system etc.) but I just can't figure out how to use it. I took a look at SharpDevelop source code but they don't use NRefactory 5 for code completion there, they only use it as decompiler. As I couldn't find an example on how to use it for code completion in the net as well I thought that I might find some help here.
The situation is as follows. I have one single file containing the script code. Actually it is not even a file but a string which I get from the editor control (by the way: I'm using AvalonEdit for this. Great editor!) and some assemblies that needs to get referenced. So, no solution files, no project files etc. just one string of source code and the assemblies.
I've taken a look at the Demo that comes with NRefactory 5 and the article on code project and got up with something like this:
var unresolvedTypeSystem = syntaxTree.ToTypeSystem();
IProjectContent pc = new CSharpProjectContent();
// Add parsed files to the type system
pc = pc.AddOrUpdateFiles(unresolvedTypeSystem);
// Add referenced assemblies:
pc = pc.AddAssemblyReferences(new CecilLoader().LoadAssemblyFile(
System.Reflection.Assembly.GetAssembly(typeof(Object)).Location));
My problem is that I have no clue on how to go on. I'm not even sure if it is the right approach to accomplish my goal. How to use the CSharpCompletionEngine? What else is required? etc. You see there are many things that are very unclear at the moment and I hope you can bring some light into this.
Thank you all very much in advance!

I've just compiled and example project that does C# code completion with AvalonEdit and NRefactory.
It can be found on Github here.

Take a look at method ICSharpCode.NRefactory.CSharp.CodeCompletion.CreateEngine. You need to create an instance of CSharpCompletionEngine and pass in the correct document and the resolvers. I managed to get it working for CTRL+Space compltition scenario. However I am having troubles with references to types that are in other namespaces. It looks like CSharpTypeResolveContext does not take into account the using namespace statements - If I resolve the references with CSharpAstResolver, they are resolved OK, but I am unable to correctly use this resolver in code completition scenario...
UPDATE #1:
I've just managed to get the working by obtaining resolver from unresolved fail.
Here is the snippet:
var mb = new DefaultCompletionContextProvider(doc, unresolvedFile);
var resolver3 = unresolvedFile.GetResolver(cmp, loc); // get the resolver from unresolvedFile
var engine = new CSharpCompletionEngine(doc, mb, new CodeCompletionBugTests.TestFactory(resolver3), pctx, resolver3.CurrentTypeResolveContext );
Update #2:
Here is the complete method. It references classes from unit test projects, sou you would need to reference/copy them into your project:
public static IEnumerable<ICompletionData> DoCodeComplete(string editorText, int offset) // not the best way to put in the whole string every time
{
var doc = new ReadOnlyDocument(editorText);
var location = doc.GetLocation(offset);
string parsedText = editorText; // TODO: Why there are different values in test cases?
var syntaxTree = new CSharpParser().Parse(parsedText, "program.cs");
syntaxTree.Freeze();
var unresolvedFile = syntaxTree.ToTypeSystem();
var mb = new DefaultCompletionContextProvider(doc, unresolvedFile);
IProjectContent pctx = new CSharpProjectContent();
var refs = new List<IUnresolvedAssembly> { mscorlib.Value, systemCore.Value, systemAssembly.Value};
pctx = pctx.AddAssemblyReferences(refs);
pctx = pctx.AddOrUpdateFiles(unresolvedFile);
var cmp = pctx.CreateCompilation();
var resolver3 = unresolvedFile.GetResolver(cmp, location);
var engine = new CSharpCompletionEngine(doc, mb, new CodeCompletionBugTests.TestFactory(resolver3), pctx, resolver3.CurrentTypeResolveContext );
engine.EolMarker = Environment.NewLine;
engine.FormattingPolicy = FormattingOptionsFactory.CreateMono();
var data = engine.GetCompletionData(offset, controlSpace: false);
return data;
}
}
Hope it helps,
Matra

NRefactory 5 is being used in SharpDevelop 5. The source code for SharpDevelop 5 is currently available in the newNR branch on github. I would take a look at the CSharpCompletionBinding class which has code to display a completion list window using information from NRefactory's CSharpCompletionEngine.
