Hey, I've been trying to get the xWinForms 3.0 library (a library with forms support in xna) working with my C# XNA Game project but I keep getting the same problem.
I add the reference to my project, put in the using statement, declare a formCollection variable and then I try to initialize it.
whenever I run the project I get stopped on this line:
formCollection = new FormCollection(this.Window, Services, ref graphics);
it gives me the error:
"
System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
Source="Microsoft.Xna.Framework"

In a project I downloaded that used the xWinForms, I put the following code in and it compiled and ran no error.
but when I put it in my project I get the error.
Am I making some stupid mistake about including dlls or something? I've been at this for hours and I can't seem to find anything that would cause this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Media;
using Microsoft.Xna.Framework.Net;
using Microsoft.Xna.Framework.Storage;
using xWinFormsLib;
namespace GameSolution
{
public class Game2 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
FormCollection formCollection;
public Game2()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
}
protected override void Initialize()
{
// TODO: Add your initialization logic here
base.Initialize();
}
protected override void LoadContent()
{
// Create a new SpriteBatch, which can be used to draw textures.
spriteBatch = new SpriteBatch(GraphicsDevice);
formCollection = new FormCollection(this.Window, Services, ref graphics);
}
protected override void Update(GameTime gameTime)
{
base.Update(gameTime);
}
protected override void Draw(GameTime gameTime)
{
base.Draw(gameTime);
}
}
}
Any help would be greatly appreciated ._.
