This is incredibly niche, but in case somebody knows I'm wondering if it's possible to get that "unsaved" marker to show in VS Code for the Web . I'm writing an extension with a custom FileSystemProvider to communicate with a remote storage service. As multiple people may have access to these files this auto-save behaviour is not appropriate.
Turns out auto save is on by default. Had to add .vscode/settings.json in the FilesystemProvider. I'll edit this answer if I find another place to override this default.

I would like to tell to ASP.NET Core application that even if appsettings.json file is there - ignore it.
I would prefer to write this as a comment but I'm still a newby here so I cannot ask questions.
I would like to understand what is the specific problem you are facing right now.
In general the usage or not of the appsettings file depends on your application.
For example, if you create a Web API using default .NET template, you can see that the appsettings file only has some configuration for logging, which you can even delete and nothing happens. You can run the application anyway and it works.
So, coming back to your question, it dependes on what your application is doing. If you have a specific library that needs to read configuration from this file, then you'll need to research how to change that default value.
If you are reading from that file, then you could set value in code instead. (this is obvious but since you didn't provide any more context I don't know what you are struggling with)
I am currently looking through the options of creating an offline indication for the nuxt/pwa project. Since this moment, app is running perfectly offline, but what I want to do is to push a small notification when there is no connection saying something simple such as "you are currently offline".
I can see that there are multiple ways of doing this such as writing the event listener directly in the default layout, but my question is which one is the most suitable and reliable for the nuxt setup.
I think you don't need to write your own event listener, as this seems to be taken care of by the nuxt already. The network status seems to be accessible via $nuxt helper's isOnline and isOffline properties. Check out this example:
https://nuxtjs.org/api/$nuxt/
I have not worked with this yet, but I think it might be what you are looking for.
Note: Make sure to copy the whole link, as stackoverflow cuts it off at /$nuxt.
I built a virtual filesystem (not a namespace extension) for Windows which acts as a frontend of our document management server consisting of files and folders. In order to be able to display some metadata of the DMS objects in Windows Explorer as additional selectable columns, I successfully provided properties to the Windows Property System by implementing a COM Property Handler. Wheras normal property handlers focus on specific file types for which they feel responsible, my Property Handler adds properties to all files regardless of their type. Because Property Handlers can only be registered on the file type level, I registered my handler for about 30 types under
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\PropertyHandlers\<.Extension>
However, I did not manage to register the Property Handler for folder objects. Since all objects in our file system are virtual I build the property store (IPropertyStore) by implementing IInitializeWithFile instead of IInitializeWithStream. The properties are requested from our DMS with the path of IInitializeWithFile acting as key and were not read from an objects content. This concept would work for folders as well.
For getting called on folders I tried to associate the handler by registering under different well known identifiers like Folder, Directory, AllFileSystemObjects and * instead of the file extension without success.
I also didn’t find anything in the MSDN documentation regarding this aspect.
Is there a way to register a Windows Property Handler on folders? Or is there some other way to add custom columns to folders in Windows Explorer?
I'm not sure if it is possible to do this.
Property handlers are clearly not the right approach, they are system wide and there can only be one per file extension. They should only be implemented by the software that "owns" the file extension and can parse the file to extract properties.
The old column handlers would have been your best bet (IMHO) but they are officially dead and you already said you can't use them.
Have you considered creating a namespace extension? Either as a root item somewhere (Desktop or My Computer) the way My Documents used to work in 2000/XP or maybe something more along the lines of how OneDrive works?
I'm not sure if desktop.ini files work in the root of a drive but it might be worth looking into. You would then find yourself in the poorly documented land of [.ShellClassInfo] and its CLSID, CLSID2 and UICLSID members. The general idea would be to act as a IShellFolder proxy on top of the "real" IShellFolder so you could create a multiplex property store. I think there are some (undocumented?) property keys you can override to change the folders default columns and tooltips as well.
There is also something called a delegated folder that allows you to play with nested PIDLs but the documentation is once again pretty useless so I'm not sure if this is something worth looking into.
A 3rd option is to pretend to be a cloud storage provider. I don't know if this gets you any closer to your goal and you would still have to implement some NSE bits to get to the point where you can layer yourself on top of the underlying IShellFolder. This feature is rather new and only documented to work on Windows 10.
The inner workings of how Explorer/IShellBrowser is connected to the IShellFolder/IShellView is one of the least documented parts of Windows. There are hundreds of undocumented interfaces. Explorer gives DefView special treatment leaving other 3rd-party implementations out in the cold.
My feeling is that there is no clean solution to implement this on top of a drive letter but you might get lucky, if Raymond Chen drops by he might have some tips for you...
I have been working on a Windows Store app where I have to support multiple configuration parameters for my app. One of the parameters is the URL the app is talking to.
For example development environment, test, acceptance and finally production.
One of the things i'm currently thinking about is what is the most efficient way of supporting all these environments with the least effort. Because there isn't some kind of config file that we can change to update these parameters I came up with some ideas. I'm curious about other options that I might have not seen.
Here are the things I came up with:
1
Adding multiple configuration to the app and than using them in code to get the correct parameter like this:
private string webserviceUrl;
#if DEV
webserviceUrl = "devUrl";
#elif TEST
webserviceUrl = "testUrl";
#endif
2
With the approach in number 1 there are a few more options available like including a config xml file bases on the configuration, or fetching configuration settings from a webservice the first time the app is running.
3
Using a branch/merge strategy and update the config files in the branch. Advantage is that the code is clean and only contains the settings it needs for the build it's created for. And the package can be build by the build server. Disadvantage is that you need to branch/merge alot.
The last option feels like the most 'clean' solution to do this. Am I missing any options, or do you have experience with any of these methods? What would you prefer?
I think the assumption is that apps in the store will always point to production.
But, in saying that, I'm facing the same issue as we're side loading the application onto devices that we control, and not using the Windows Store at all.
To answer your question, I prefer option 1.
Option 2 and the xml/json config file seems like the best option though.
The webservice option probably won't work. What webservice URL do you use? And how will it work if you want some instances pointing to different environments as they will all be fetching the config from the same URL.
Another option you might want to consider would be options in the settings charm menu. For example, use radio buttons for the environments, and allow the user to configure which environment they want to target.
The issue would be locking it down in production for end users so that it isn't modifiable any more. Perhaps once "PROD" radio is selected, all the radio buttons are then hidden.
If you're deploying the application through side loading, then these settings could probably be configured during the install process.
I'd be interested to hear other opinions as well. This is also an old question, so I'd like to know what solution you decided on implementing.
Is it possible to write a key logger in Visual Basic.NET? Is this the right language to be using?
So far, I've gotten a console app to read input and append to a file.
1)How can I make a .NET program "catch" all keyboard input?
2)How do I make a process not show up in Task Manager?
This is not for a virus, but rather a parental control program for a specific clientele. No malicious intent here.
You need to set a Keyboard Hook.
This is extremely difficult and is not possible on 64-bit editions of Windows.
If you're really doing this with consent, this shouldn't be necessary.
Here's a sample of how to write a key logger in .net. http://www.scratchprojects.com/2008/09/csharp_keylogger_p01.php
Your best bet for making it not show up in Task Manager is to make it look like something that belongs. Call it "svchost.exe". :-)
