C# - EnumDisplaySettings() returns a wrong dmPelsWidth

[FIXED] C# - EnumDisplaySettings() returns a wrong dmPelsWidth

Hi,
I tried making my own plugin for Sharpcraft but it's not working the way i want to.

The Plugin is meant to get the screen resolution and sets the mousecursor in the middle of the screen and it's working in general...the only thing is, that dmPelsWidth is set to '32' and not '1050' as it should be...dmPelsHeight is set to '1680'.

Does somebody has an idea, what could be wrong?

Does this work?

EnumDisplaySettings(null, -2, ref vDevMode);

Also, do you need EnumDisplaySettings for some reason or can you use another method of getting the resolution?

 

[Cataract92]

changing to -2 didn't work.
I'm not really into C# and the only two function i found on the internet were EnumDisplaySettings() and Screen.PrimaryScreen.Bounds, but Screen.PrimaryScreen.Bounds is just for a window.form which Sharpcraft doesn't have, afaik.

Here's the output i get:

 

[deathismyfriend]

I'm not sure about sharpcraft but this is what I use to display the resolution in any of my programs. It is in C#

System.Windows.Forms.MessageBox.Show("Height = " + System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height.ToString()
                        + " Width = " + System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width.ToString());

Without the message box i use to show the screen.

System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height
System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width

 

[Cataract92]

Yeah...i tried it, but i got an error, that Sharpcraft couldn't find the "Forms" in System.Windows and i looked it up and it said, that it's just for C# Windows Presentation Foundation (WPF) and because Sharpcraft doesn't have any GUI i think that sharpcraft isn't a WPF-project

 

[deathismyfriend]

I don't use WPF. Did you try to include the reference ? It may need an additional dll file that you are not using.

 

[Cataract92]

okay, I did a bit of research. To use screen class i have to add the System.Windows.Forms.dll, the only problem is that it isn't in sharpcraft yet. So I have to add the .dll on the fly to my .cs file to get the class Screen. I got to the point where i have to use the Assembly-class, but i can't find anything about adding a class to the code...everything i can find is just adding a method to the code. For Example
Does somebody of you has any idea how to do it?

 

[Crazed_seal2]

Add a reference to your project.

 

[Cataract92]

The problem is, that I only have one .cs file...no project.
And if I release my map I just want the player to download the additional plugin and copy it into the sharpcraft/plugins folder and I have no idea in which file the refernces of a project are saved so I can put it which my plugin in a .rar file.

 

[Crazed_seal2]

So Sharpcraft handles the compiling and stuff..

This MIGHT work:

public const int WIDTH = 0;
public const int HEIGHT = 1;
[DllImport("user32.dll")]
public static extern int GetSystemMetrics(int nIndex);

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace Resolution
{
    class Program
    {
        public const int WIDTH = 0;
        public const int HEIGHT = 1;
        [DllImport("user32.dll")]
        public static extern int GetSystemMetrics(int nIndex);
        static void Main(string[] args)
        {
            Console.WriteLine("Width: " + GetSystemMetrics(WIDTH));
            Console.WriteLine("Height: " + GetSystemMetrics(HEIGHT));
            Console.Read();
        }
    }
} // Full Example Code, for Console Application.

It's working perfectly
Thanks alot!

Why didn't i find it on my research?
Everybody was just talking about GetEnumDisplaySettings() and the Screenclass...

Maybe i should have had a closer look to the user32.dll because it's already a references...

It's usually not indicated anywhere since it's a non-managed library, and as such many programmers don't even know about it's existence, not to mention it's functions.

Also, I wonder what it returns on multiple screens for width - it may just display the sum of the screen width, but never tried getting the screen resolution with it.

It only returns the primary monitor, if you want the width of all the screens then you can:

Width: 78
Height: 79
