For testing my roaming and/or local settings, I'd like to be able to clear all the settings.
I could do it like so, I guess:
App.roamingSettings.Value["SomeVal"] = string.Empty;
App.roamingSettings.Value["SomeOtherVal"] = string.Empty;
App.roamingSettings.Value["YetAnotherVal"] = string.Empty;
...
etc.
...but I'd rather have some quicker, cleaner (no pun intended) way. Is there one?
Also, relatedly, it would be nice to have a "Settings Manager" utility for quickly verifying they are what you think they are, too. Does anybody know of one?
UPDATE
This is my attempt to "roll my own" based on the answer; so far, no go:
string roamingSettingPairs = string.Empty;
for (int i = 0; i < App.roamingSettings.Values.Count; i++)
{
// Print out whatever you want to verify that everything is as it should be
//string roamingSettingName = App.roamingSettings.Name[i].ToString();
//string roamingSettingValue = App.roamingSettings.Values[i].ToString();
Dictionary<string, object> roamingSettingVals = App.roamingSettings.Values;
string roamingSettingName = roamingSettingVals.Keys[i];
object roamingSettingObj = roamingSettingVals.Values[i];
//roamingSettingPairs = string.Format("{0}{1}={2}{3}", roamingSettingPairs, roamingSettingName,
// roamingSettingValue, Environment.NewLine);
}
You can delete all of your roaming settings using this code:
ApplicationData.Current.RoamingSettings.Values.Clear();
For a Settings Manager, I would probably just use a for loop like so:
for (int i = 0; i < ApplicationData.Current.RoamingSettings.Values.Count; i++)
{
// Print out whatever you want to verify that everything is as it should be
}

I decided to get into coding and am learning c#, after making a few small projects, I decided to step it up a little and make a text adventure game, with saving and loading, and if I get to feeling zany I'll try to add some multiplayer. While I haven't really hit a road block because of it, I can't help but feel that I am doing load function REALLY sub-optimally. The save is fine, I feel like it works for me, but the load I feel can be really simplified, I just don't know what to use.
I also wouldn't really mind, but with this way, if I add other attributes/skills or whatever else that needs to be saved, I will have to add everything to the load function as well, and it will be even longer.
I have tried to search around on here, the c# documentation, and other sites, but can't find a solution that works for this case. can anyone help me find a better way of doing this? Or is this the best I can really do since it's varying data types?
Edit: To simplify and clarify what answer I am searching for, I am trying to find a simpler and more scalable way to save and load the data to a file.
static void LoadGame(CharData PlayerData)
{
Console.WriteLine("Enter the name of the character to load as shown below.");
//getting current directory info, setting to di
DirectoryInfo di = new DirectoryInfo(Directory.GetCurrentDirectory());
//need to initialize these outside of a loop
int SaveFiles = 0;
string DisplayName = " ";
int DisplayNameLength = 0;
//looks through files in working directory ending in '.fasv', displays them in format '{x}. John Smith'
foreach (var fi in di.GetFiles("*.fasv"))
{
SaveFiles++;
DisplayNameLength = fi.Name.Length;
//remove .fasv from displayed name to make it look nicer
DisplayName = fi.Name.Remove(DisplayNameLength - 5, 5);
Console.WriteLine(SaveFiles.ToString() + ". " + DisplayName);
}
string toLoad = Console.ReadLine();
using StreamReader sr = new StreamReader(toLoad + ".fasv");
//the name is easy to get since it's a string. but integers...
PlayerData.Name = sr.ReadLine();
//... not so much. i hate all of this and i feel like it's gross, but i don't know how else to do it
int hp, xp, level, toughness, innovation, mind, empathy, spryness;
Int32.TryParse(sr.ReadLine(), out hp);
Int32.TryParse(sr.ReadLine(), out xp);
Int32.TryParse(sr.ReadLine(), out level);
Int32.TryParse(sr.ReadLine(), out toughness);
Int32.TryParse(sr.ReadLine(), out innovation);
Int32.TryParse(sr.ReadLine(), out mind);
Int32.TryParse(sr.ReadLine(), out empathy);
Int32.TryParse(sr.ReadLine(), out spryness);
PlayerData.Health = hp;
PlayerData.Level = level;
PlayerData.XP = xp;
PlayerData.Toughness = toughness;
PlayerData.Innovation = innovation;
PlayerData.Mind = mind;
PlayerData.Empathy = empathy;
PlayerData.Spryness = spryness;
sr.Close();
InGame(PlayerData);
}
static void SaveGame(CharData PlayerData)
{
using (StreamWriter sw = new StreamWriter(PlayerData.Name + ".fasv"))
{
foreach (System.Reflection.PropertyInfo stat in PlayerData.GetType().GetProperties())
{
//write player data properties to file line by line, using stat to iterate through the player data properties
sw.WriteLine(stat.GetValue(PlayerData));
}
sw.Close();
}
}
If you aren't set on a particular data format for the file data, I would recommend using a serializer such as JSON.NET. You can use NuGet to add newtonsoft.json to your project, and that would allow you to just do something similar to:
using (StreamWriter file = File.CreateText(pathToPlayerFile))
{
var serializer = new JsonSerializer();
serializer.Serialize(file, playerData);
}
And then your code to read from the file would be pretty similar:
using (var file = File.OpenText(pathToPlayerFile))
{
var serializer = new JsonSerializer();
return (CharData)serializer.Deserialize(file, typeof(CharData));
}
I borrowed those code snippets from newtonsoft.com. CreateText will create (or overwrite) the file and write the object as a JSON object.
I'am using [Akka.Net 1.3.1] a mix of ReceiveActors and ReceivePersistentActors and now I want to write tests for my actorsystem.
MyPersistentActor inherits from ReceivePersistentActor and MyActor inherits from ReceiveActor.
I also installed Akka.TestKit using version 1.3.1 .
But it seems that only ReceiveActors can be tested by Akka.TestKit.
IActorRef myActorRef = this.Sys.ActorOf<MyActor>(); // is fine
IActorRef myPersistentActorRef = this.Sys.ActorOf<MyPersistentActor>(); // is a problem
I also found the nuget package Akka.Persistence.TestKit version 1.2.3.43-beta . The beta wasn't changed since three month and only support akka 1.2.2 . Is it still in development or is it dead. I can not find any kind of information regarding that.
How do you test your persistent actors?
Thanks for your help!

Akka.Persistence.TestKit has been renamed to Akka.Persistence.TCK and it is used only for testing custom event journal and snapshot store implementations for compatibility with Akka.Persistence protocol. It doesn't bring any utilities for testing user actors.
There are no built-in methods to cooperate with journals/snapshot stores for testing purposes beside having implementations of them working in-memory. With that being said, you can actually work with journal/snapshot store just like with any other actor. If you look into implementations of persistence TCK specs like JournalSpec, you may get some insights into how that protocol works.
For example, if you want to initialize your journal with some events before firing the test case, you can do it like following:
void InitWithEvents(string persistenceId, params object[] events)
{
var probe = CreateTestProbe();
var writerGuid = Guid.NewGuid().ToString();
var writes = new AtomicWrite[events.Length];
for (int i = 0; i < events.Length; i++)
{
var e = events[i];
writes[i] = new AtomicWrite(new Persistent(e, i+1, persistenceId, "", false, ActorRefs.NoSender, writerGuid));
}
var journal = Persistence.Instance.Apply(Sys).JournalFor(null);
journal.Tell(new WriteMessages(writes, probe.Ref, 1));
probe.ExpectMsg<WriteMessagesSuccessful>();
for (int i = 0; i < events.Length; i++)
probe.ExpectMsg<WriteMessageSuccess>();
}
PS: There is clearly a missing part in the persistence TestKit API, any contributions on that field are more than welcome.
I know this is an ols answer, but I couldn't find any better resource. In my tests I am actually only interested if the correct event(s) is (are) persisted after I give my command. Multiple events could be raised by starting a saga. Most of the time I am only interested in the last persisted event.
If somebody is hitting the same issue as me, this is how I fixed getting the last message, based on Bartosz initWithEvents.
private void InitWithEvents(string persistenceId, IList<object> events)
{
var probe = CreateTestProbe();
var writerGuid = Guid.NewGuid().ToString();
var writes = new AtomicWrite[events.Count];
for (int i = 0; i < events.Count; i++)
{
var e = events[i];
writes[i] = new AtomicWrite(new Persistent(e, i+1, persistenceId, "", false, ActorRefs.NoSender, writerGuid));
}
journal = Persistence.Instance.Apply(Sys).JournalFor(null);
journal.Tell(new WriteMessages(writes, probe.Ref, 1));
probe.ExpectMsg<WriteMessagesSuccessful>();
for (int i = 0; i < events.Count; i++)
probe.ExpectMsg<WriteMessageSuccess>();
}
private object GetLastPersistedMessageFromJournal(string persistenceId)
{
var repointable = journal as RepointableActorRef;
var underlying = repointable.Underlying as ActorCell;
PropertyInfo prop = typeof(ActorCell).GetProperty("Actor", BindingFlags.NonPublic | BindingFlags.Instance);
MethodInfo getter = prop.GetGetMethod(nonPublic: true);
MemoryJournal jrnl = getter.Invoke(underlying, null) as MemoryJournal;
var read = jrnl?.Read(persistenceId, 0, Int64.MaxValue, Int64.MaxValue);
return read?.Last().Payload;
}
I am using C# with Microsoft.Web.Administration to remove all of the apps inside of a site. I do not want to remove the site app itself (path = "/").
Here's the code:
ServerManager manager = new ServerManager();
for (int i = 0; i < manager.Sites[siteName].Applications.Count; i++)
{
if (manager.Sites[siteName].Applications[i].Path != "/")
{
manager.Sites[siteName].Applications.RemoveAt(i);
}
}
manager.CommitChanges();
What happens with this code is that some apps get removed and others don't, and which apps get removed and which don't are different each run.
manager.Sites[sitename].Applications.Clear();
will work, but it will also remove the application with path = "/", which I don't want.
I tried doing something like this, too:
Application baseApp = null;
for (int i = 0; i < manager.Sites[siteName].Applications.Count; i++)
{
if (manager.Sites[siteName].Applications[i].Path == "/")
{
baseApp = manager.Sites[siteName].Applications[i];
}
}
manager.Sites[siteName].Applications.Clear();
if (baseApp != null)
{
manager.Sites[siteName].Applications.Add(baseApp);
}
manager.CommitChanges();
But that didn't work either. The app with path = "/" was never re-added, or wasn't added properly.
Is there anyone with more experience with Microsoft.Web.Automation who has some insights on removing more than one app at a time that can help me out with this?
As it turns out, I was making the classic stupid mistake of altering the collection while enumerating through it. The first app would be removed and the count would go down. Some apps were never getting looked at. The randomness of the removal was simply due to the unordered nature of the collection. Silly me!
This works:
List<Application> appsToRemove = new List<Application>();
for (int i = 0; i < manager.Sites[siteName].Applications.Count; i++)
{
if (manager.Sites[siteName].Applications[i].Path != "/")
{
Console.WriteLine("Removing {0}", manager.Sites[siteName].Applications[i].Path);
appsToRemove.Add(manager.Sites[siteName].Applications[i]);
}
}
foreach (Application a in appsToRemove)
{
manager.Sites[siteName].Applications.Remove(a);
}
manager.CommitChanges();
Suppose I have a program which allows a user to upload any kind of file. Along with getting generic information such as file type and file size, I would like to attempt to grab any extra information (such as document properties like author, last revised, etc) that may be transported along with the document.
Since I don't have any knowledge about the incoming document/file ahead of time, I can't simply use classes that are specific to, say Microsoft Office docs. I need to do this generically and then construct a dynamic object or dictionary to hold any found key/value results.
Is this possible? If so, how? Any help is appreciated!
I found a few answers on StackOverflow for this, but none gave me a nice, clean dictionary of document properties. Here is what I finally came up with and it seems to be working nicely (you will need to reference "Microsoft Shell Controls and Automation" from the COM folder and add using Shell32; to your code:
public static Dictionary<string,string> GetDocumentMetadata(string fileName)
{
var properties = new Dictionary<string,string>();
var arrHeaders = new List<string>();
var shell = new Shell();
var objFolder = shell.NameSpace(HttpContext.Current.Server.MapPath("~/RawFiles"));
var file = objFolder.ParseName(fileName);
for (var i = 0; i < short.MaxValue; i++)
{
var header = objFolder.GetDetailsOf(null, i);
if (String.IsNullOrEmpty(header))
break;
arrHeaders.Add(header);
}
for (var i = 0; i < arrHeaders.Count; i++)
{
var value = objFolder.GetDetailsOf(file, i);
if (!String.IsNullOrEmpty(value))
{
properties.Add(arrHeaders[i], value);
}
}
return properties;
}
Using the Visual Studio C# Winforms Google Earth plugin, 4 placemarks have been added to the globe as can be seen in the picture below:
My goal is to be able to remove the linestring placemark. The steps would seem to be to get all the placemarks, find the linestring and remove it.
Here is the code being used to create the linestring placemarks (more or less from the API website)
var lineStringPlacemark = ge2.createPlacemark("Line_" + name);
// create the line string geometry
var lineString = ge2.createLineString("");
lineStringPlacemark.setGeometry(lineString);
// add the the points to the line string geometry
double dlat1 = Convert.ToDouble(lat1) / 100000;
double dlon1 = Convert.ToDouble(lon1) / 100000;
double dlat2 = Convert.ToDouble(lat2) / 100000;
double dlon2 = Convert.ToDouble(lon2) / 100000;
lineString.getCoordinates().pushLatLngAlt(dlat1, dlon1, 0);
lineString.getCoordinates().pushLatLngAlt(dlat2, dlon2, 0);
// Create a style and set width and color of line
lineStringPlacemark.setStyleSelector(ge2.createStyle(""));
var lineStyle = lineStringPlacemark.getStyleSelector().getLineStyle();
lineStyle.setWidth(5);
lineStyle.getColor().set("9900ffff"); // aabbggrr format
// Add the feature to Earth
ge2.getFeatures().appendChild(lineStringPlacemark);
And here is the code I ended up using to remove the line. Note that the GEHelpers.RemoveFeatureById(ge2, s); is commented out since it isn't working for me for some reason.
for (int i = 0; i < ge2.getFeatures().getChildNodes().getLength(); i++)
{
var kmlobject = ge2.getFeatures().getChildNodes().item[i];
string s = kmlobject.getId();
if (s.Contains("Line_"))
{
ge2.getFeatures().removeChild(kmlobject);
kmlobject.release();
//GEHelpers.RemoveFeatureById(ge2, s);
}
}
The line you have should work and remove all the currently loaded content.
GEHelpers.RemoveAllFeatures(ge); // removes all loaded features from 'ge'
If you wish to remove a specific placemark, or any other feature, simply specify its ID as the parameter to the RemoveFeatureById method.
GEHelpers.RemoveFeatureById(ge, 'foo'); // remove the feature with the id 'foo'
An ID can be set either when you create the feature via the api or when you define the feature in kml. e.g.
// api
ge.createPlacemark('foo');
//kml id
<Document id="foo">
</Document>
Edit:
You should not have to do anything other than...
for (int i = 0; i < ge2.getFeatures().getChildNodes().getLength(); i++)
{
var kmlobject = ge2.getFeatures().getChildNodes().item[i];
if (kmlobject.getId().Contains("Line_"))
{
ge2.getFeatures().removeChild(kmlobject);
}
}
I think that there is possibly something else going on with your set up, maybe to do with having multiple instances of the plugin running at the same time.
