sfml.net compiles but doesn't let me use it in a user control

[Shadowblitz16]

does anybody know why my project compiles but when I try to add my SFMLCanvas to my form it throws an error?

I have don't the following..
-added sfmlnet-audio-2 to references
-added sfmlnet-graphics-2 to references
-added sfmlnet-system-2 to references
-added sfmlnet-window-2 to references

-added all extlibs to root of project and set output directory to "Copy id newer"

and this is my code..

Code: [Select]

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using SFML.Graphics;
using SFML.Window;

namespace Zelda_2_Editor
{
    public partial class SFMLCanvas : UserControl
    {
        public RenderWindow renderwindow;
        public SFMLCanvas()
        {
            InitializeComponent();
            renderwindow = new RenderWindow(this.Handle);
        }

        protected override void OnPaint(PaintEventArgs e)
        {
            System.Windows.Forms.Application.DoEvents();
            renderwindow.DispatchEvents();
            renderwindow.Clear(SFML.Graphics.Color.Green);
            renderwindow.Display();
        }
        protected override void OnPaintBackground(PaintEventArgs pevent)
        {

        }
    }
}

here is what it looks like when it happens


can somebody tell me whats wrong and how to fix it?

You need the CSFML binaries to be in the same directory as the .NET libraries.

thats not much help since I have all the dlls copied to the bin/Debug folder

here is the project if you don't believe me.

I don't know if it's the same for .NET as for C++.
Do .NET's debug DLLs also have "-d"?

[Shadowblitz16]

no but I found what the issue is partially.
you can't use external libraries like smfl.net during design time.

I fixed it with the sfmlCanvas by doing..

Code: [Select]

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using SFML.Graphics;
using SFML.Window;

namespace Zelda_2_Editor
{
    public partial class SFMLCanvas : UserControl
    {
        public RenderWindow renderwindow;
        //public SFML.Graphics.Color DrawColor;
        public SFMLCanvas()
        {
            InitializeComponent();
        }

        protected override void OnLoad(EventArgs e)
        {
            if (!DesignMode)
            {
                renderwindow = new RenderWindow(this.Handle);
                //DrawColor = SFML.Graphics.Color.Black;
            }
            base.OnLoad(e);
        }

        protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            if (!DesignMode)
            {
                Application.DoEvents();
                renderwindow.DispatchEvents();
                renderwindow.Clear(SFML.Graphics.Color.Black);
                renderwindow.Display();
            }
        }
        protected override void OnPaintBackground(PaintEventArgs pevent)
        {
            base.OnPaintBackground(pevent);
        }
    }
}
sadly it still crashes when I add that userControl to another userControl and then add that in the designer.

for example this code doesn't work because it has a sfmlCanvas in it.

Code: [Select]

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using SFML.Graphics;

namespace Zelda_2_Editor.Controls
{
    public partial class SFMLButton : UserControl
    {
        public SFMLButton()
        {
            InitializeComponent();
            //Text = "";
        }

        protected override void OnLoad(EventArgs e)
        {
            if (!DesignMode)
            {
                //sfmlCanvas.DrawColor = new SFML.Graphics.Color(BackColor.R, BackColor.G, BackColor.B);
                sfmlCanvas.Enabled = false;
            }
            base.OnLoad(e);
        }
    }
}

I had this exact same issue & came to the same conclusion you did. Sadly this is the case.

You might try taking a look at this workaround and see how it works for you: https://stackoverflow.com/a/6036800

I shouldn't have to add sfml to my path variables

this is obviously a conflict between sfml and winforms if you would like to link a sfml render window control I would be glad to try it.
