So, I am making a custom plugin for my server, and one of my features requires me to set an integer in a gui that shows how many 'CommonPackages' a user has. The issue that I am having is that when I am getting the String from my config (My config uses a custom file creation/management class that was given to me by a friend) it is saying that it is null in the gui, I do not get any errors in the console, please may someone help me? The item in the gui and the code for setting the item in the gui.
Item in the gui
gui creation code:
public static Inventory WhiteBackpack(Player player) {
UUID uuid = player.getUniqueId();
Inventory inv = Bukkit.createInventory(null, 27, (inventoryname));
ItemStack common = new ItemStack(Material.INK_SACK);
common.setDurability((byte) 8);
ItemMeta commonMeta = common.getItemMeta();
commonMeta.setDisplayName(Utils.chat("&fCommon Packages &8ยป &f&l" + Main.pl.getFileControl().getConfig().getString("players." + uuid + ".Packages.Common"))); //How I access my custom configs.
common.setItemMeta(commonMeta);
inv.setItem(10, common);
return inv;
}
Without the code of your method to get the config I can only say that the string in the actual file is not present.
As the Bukkit documentation states:
If the String does not exist and no default value was specified, this will return null.
So either the key just does not exist in the file or you pointed to the wrong file. The configuration should be well formated, too. (no tabs, only spaces)

Can someone please help me with this, am trying to use OpenFileDialog class from System.Windows.Forms to open a file dialog and read the selected file. Then, this error showed up. I've referenced it but still the same, below is the code.
`using UnityEngine
using UnityEngine.UI
using System.Windows.Forms;
public class OpenFileButtonScript : MonoBehaviour
{
public TextFieldScript textFieldScript;
public void OpenFile()
{
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "Text Files (*.txt)|*.txt|All Files (*.*)|*.*";
openFileDialog.FilterIndex = 1;
openFileDialog.Multiselect = false;
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
string filePath = openFileDialog.FileName;
string text = System.IO.File.ReadAllText(filePath);
textFieldScript.inputField.text = text;
}
}
}`
It may look like you have access to all of the native Window system libraries, but it just looks like it. In actuality, a lot of the time you're simply given stubs, or shims, that look like the full Window libraries, because there's a certain element that Unity wants to use from those namespaces. If you think about it, the code you present above, what do you think it should do on Android or Nintendo devices? The simple answer is, it simply won't work.
Generally in cases like this, you have to gain access to the native operating system, and perform those calls directly. For example, there is a file browser asset on the Asset Store, that does this for you. It's not free, because the process isn't trivial.
Depending on how much effort you want to put in, you CAN read files from the local file stores (to varying degrees based on platform). It's possible to read the list of files in a location, and use either uGUI or UIToolkit to create your own File Open Dialogue box. Again, this isn't a trivial task either. So you have to be sure that you'd want to go down that path.
Is it possible for a visual studio code extension to make a file-path use a specific language, like files.associations.
This is to associate a json schema with a specific unusual json file, with its schema. The schema association is working fine, but only if I manually set the file grammar to json. Is there any way to do this automatically with the extension (not for example by adding an association in user settings).
Edit: 6th October
Still unresolved, cannot see an official way to do this, however, I have got it working by doing:
let config = vscode.workspace.getConfiguration()
if (config.get("files.associations")["*.mcmeta"] == undefined && !context.globalState.get("mcmeta- updated")) {
let object = config.get("files.associations");
object["*.mcmeta"] = "json";
config.update("files.associations", object, true);
vscode.window.showInformationMessage("...");
}
context.globalState.update("mcmeta-updated", true);
Which is essentially a massive hack to update the files.association property in the global settings
I am doing a simple createAsync() with my ZooKeeperNetEx nuget package and it is throwing an exception which is triggered by a MARSHALLINGERROR.
Here's is the two-line summary (between these lines, the connection successfully confirmed to Zookeeper):
var Zoo = new ZooKeeper("localhost:50002", 5000, new ClusterWatcher());
. . .
var parentNode = Zoo.createAsync("/election", null, null, CreateMode.PERSISTENT).Result
I do not get it. ClusterWatcher is my own class derived from Watcher, of course. Yes, I am writing this in C# but this such a simple matter, I would not think it mattered. The host machine is running Windows 10 Pro, if that matters.
This exception can be triggered by not specifying the ACL mode (you seem to pass null). In Java you can pass the predefined list ZooDefs.Ids.OPEN_ACL_UNSAFE (for example, or one of the others in that class) for the ACL mode; for C# there will probably be a similarly named constant.
In the Java client library this is a convenience constant that is defined as:
/**
* This is a completely open ACL .
*/
public final ArrayList<ACL> OPEN_ACL_UNSAFE = new ArrayList<ACL>(
Collections.singletonList(new ACL(Perms.ALL, ANYONE_ID_UNSAFE))
);
I have been attempting to figure out how to make the EF Power Tools - Reverse Engineer Code First use a different name for the generated Context-file, than what it uses now.
Example
I have a database called My_Awesome_Dev_Database. When I run Reverse-engineer against that, the file that is generated will be called:
My_Awesome_Dev_DatabaseContext.cs
What it would like to do is specify what the file is to be called, for instance:
MyAwesomeDatabaseContext.cs
Attempts so far
I have tried looking through the EF.Utilities.CS.ttinclude file, to figure out how the filename is generated - but I have been unsuccessful so far.
Does anyone know ?
Thanks in advance!
Currently the generated context file naming convention is hard-coded and non configurable.
All the logic is inside the ReverseEngineerCodeFirstHandler class (the source is on CodePlex).
It sets the context file name and path with
var contextFilePath = Path.Combine(modelsDirectory,
modelGenerator.EntityContainer.Name + contextHost.FileExtension);
var contextItem = project.AddNewFile(contextFilePath, contextContents);
So the file name is coming from modelGenerator.EntityContainer.Name which gets created upper in the method with:
var contextName =
connection.Database.Replace(" ", string.Empty)
.Replace(".", string.Empty) + "Context";
var modelGenerator =
new EntityModelSchemaGenerator(storeGenerator.EntityContainer,
"DefaultNamespace", contextName);
So as you can see the tool just takes the db name removes the spaces and dots and use it as the context name which will end up as the generated file name.
You can open an issue or - because Entity Framework is open source - take the code, add this configuration option, and send back a pull request.
I am playing around with creating a T4 template for the "DDL Generation Template option" (model first) process in Visual Studio 2010 RC. Is it possible to retrieve the connection string that is associated with that process? If I right click on the .edmx file and choose "Generate Database from Model..." I have the option of choosing a data connection. That connection string is saved to the app.config (assuming that the option is checked). So I am wondering if it is possible to retrieve that connection string inside the T4 template. I would like to generate different information from the template based on the connection string.
More generally, is it possible to get any context information in this situation? So far, the only thing I have successfully retrieved is the .NET data provider name.
Note - I have studied the ideas provided by Craig but am only getting the name of the IDE (devenv.exe), which quite possibly means I am just doing something wrong.
In case this helps anyone else, here is a snippet I created to read the Entity Framework connection string from inside T4. You pass it the model name (which is also the name of the connection string). It finds and parses just the connection bit I need. It also throws helpful errors when it does not succeed.
To use:
A. Paste this at the top of your template if you aren't already referencing these assemblies:
<## assembly name="EnvDTE" #>
<## assembly name="System.Configuration" #>
B. Paste this ugly (but compact) code at the end of your template:
<#+
string GetEFConnectionString(string modelName)
{
string file = null, key = "provider connection string=\"";
foreach (EnvDTE.ProjectItem item in ((EnvDTE.Project)((Array)((EnvDTE.DTE)((IServiceProvider)this.Host).GetService(typeof(EnvDTE.DTE))).ActiveSolutionProjects).GetValue(0)).ProjectItems)
if (System.Text.RegularExpressions.Regex.IsMatch(item.Name, "(app|web).config", System.Text.RegularExpressions.RegexOptions.IgnoreCase)) {
file = item.get_FileNames(0); break;
}
if (file == null) throw new Exception("config file could not be found");
var config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(new System.Configuration.ExeConfigurationFileMap() { ExeConfigFilename = file }, System.Configuration.ConfigurationUserLevel.None);
var cn = config.ConnectionStrings.ConnectionStrings[modelName];
if (cn == null) throw new Exception(modelName + " connection string could not be found");
string s = cn.ConnectionString;
int pos = s.IndexOf(key,StringComparison.OrdinalIgnoreCase);
if (pos<0) throw new Exception("could not find value '" + key + "' inside connection string");
pos += key.Length;
int pos2=s.IndexOf('"',pos);
if (pos2 < 0) throw new Exception("could not find ending \" in connection string");
return s.Substring(pos,pos2-pos);
}
#>
C. Use it like such:
using(var connection = new SqlConnection(GetEFConnectionString("Database"))) {
..
}
I posted my question on one of the MSDN forums and got a response from Lingzhi Sun who pointed me in the direction of a couple of links at skysanders.net. The second of these links has a very nice example of getting to the app/web.config file and, specifically the part I wanted, the connection strings. It doesn't give any information on the specific connection string for the scenario I described in the original question, but this gets me close enough.

Well, the EF connection string will always have the same name as the model, right? The DB connection string will be embedded in the EF connection string. So I'd say you should be able to get it, at least indirectly, via the EF connection string.
Because you're not running in the assembly, have to specify the config file name.
So it would be something like:
var config = ConfigurationManager.OpenExeConfiguration(name);
var cs = config.ConnectoinStrings[modelName];
Note that name, here, is supposed to be an EXE name. But in the IDE, your config fine is going to be called App.config rather than MyApp.dll.config. So you may have to play around with this to get it to work -- try using "App" as the EXE name!
Worst case is open it as a file and then use the config manager.
