It works for me - I just tried a new project in VS2017 (a .NET console since it's the simplest), added the reference to System.Management, and added your code:
namespace ConsoleApp1
{
class Program
{
private static ManagementScope oManagementScope = null;
static void Main(string[] args)
{
oManagementScope.
}
}
}At the ".", intellisense lists all the properties and methods I would expect.
What am I doing that is different to you?

You're adding a reference to the assembly.

Probably, but ... is ManagementScope in .NET Core?
We don't know what exactly he is doing, so find one that works, and see how it differs is a start at least...

Typing in System.Management. Intellisense only displays "Instrumentation" as a member for me. It is the only member....
|
|
|
|
|
What kind of project are you working on?
I get the full list (including Instrumentation).
Have you tried turning it off and back on again?
(I know, I know - but it's worth a try - I hear a few bad things about VS2017 getting confused at times.)

THanks, I closed VS and opened it again and no better.  I created a new Console app like you did. Under C#, I selected "Windows Classic Desktop", then "Console App(.NET Framework). added using System.Management;
still it does not recognize ManagementScope.
Could it be that I need to install/add an assembly or something to VS2017? Just guessing here....

Just adding the using does not reference the assembly. Right-click on the project, go to references, and add it.

As Eddie says - and I mentioned in my original answer - you need a reference:
Quote: ...added the reference to System.Management...
Open the Project in the Solution Explorer pane, right click "References", select "Add Reference...", then tick the checkbox to the left of the "System.Management" assembly under the "Assemblies...Framework" selector on the left hand side. Click OK, and it'll appear in the references list for the project.

I have an Ink Canvas control on my application. Is it possible that whenever i draw a line, there's a value that appears between on that line by the use of C#?
Here is my code, XAML:
<DockPanel>
<StackPanel DockPanel.Dock="Bottom">
<Button x:Name="ClearButton" Content="Clear" Click="ClearButton_Click"/>
<Button x:Name="SaveButton" Content="Save" Click="SaveButton_Click"/>
</StackPanel>
<InkCanvas x:Name="DrawingPane" Cursor="Cross" Background="White"/>
</DockPanel>
And here is my C# code:
namespace WpfApp1
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.WindowStartupLocation = WindowStartupLocation.CenterScreen;
}
private void ClearButton_Click(object sender, RoutedEventArgs e)
{
DrawingPane.Strokes.Clear();
}
}
}
I hope you can help me out for this. Thank you.

Since this is not "just" C#, you should post this in the right forum: Silverlight / WPF Discussion Boards[^] for the best results.

This is from the top of my head so you'll have to work out the details yourself.
Catch the events mousedown and mousemove. If the mouse moves AND mouse button is down you're drawing (or so I assume).
You'll need to find out the coordinates from your canvas where top-left = 0,0 and x moves up to the right and y moves up going down! It might be you need to fiddle with it to get the right coordinates as windows tends to work with multiple sets (your window, your control, the screen, ...)
Once you have the correct coordinates and you start drawing a line (= first point is known) you can calculate the length of your line: sqrt((x2-x1)^2 + (y2-y1)^2) use your mouse location to get the second point.
To set that value on screen, draw a string on the location (x2+x1)/2 and (y2/y1)/2.
This solution should at least get you a bit further, but again, this is on top of my head, you'll need to figure out a lot of it yourself.

You don't draw "between" an object (i.e. the line); only "over" (or under).
Determine "where" the "value" should go, and simply place a Label, TextBlock, TextBox, Image, etc. with the appropriate styling (e.g. Margin; transparent background) there.

OK I install it and I give you the rest
thank you for your promptitude
|
|
|
|
|
Thank you thank you and thank you you just relieved me of a problem that tired me for a long time. I followed your advice and walk. But my question is the following, if I will have to burn it on a CD to give it to a friend or mm has everyone how to go about it so that in the course of installatoin the sytem.data.sqlite installs automatically?
|
|
|
|
|
You need to follow the instructions of your setup builder. I think external libraries need to be added as dependencies.
|
|
|
|
|
I use inno setup. i made a comment when i was installing my program on the pc it asked me the framwork .NET 3.5 which is launching once i have accepted but for the system.data.sqlite no ...
|
|
|
|
|
SQLite is not part of the standard .NET framework, it must be downloaded from the SQLite website.
|
|
|
|
|
Hello sir and thank you for your answer ...
I will like some advice about my program. If I want to give it to friends, I have to ask them to install system.data.sqlite on their pc? But is there not another alternative?
|
|
|
|
|
The alternative is that you add the requirement to your setup program, so it is automatically installed. Check the documentation for the setup generator that you are using.
|
|
|
|
|
Thank you I use inno setup, I will document and make you a continuation of my research
|
|
|
|
|
I just realized that although I managed to connect to my database thanks to you, I can not register ... here is the error message:
Failed to connect to the data source attempt to write a readonly database
