        private static extern bool cdtInit(ref int width, ref int height);
 
        [DllImport("cards.dll")]
        private static extern bool cdtDraw(IntPtr hdc,
                                            int x,
                                            int y,
                                            int card,
                                            int mode,

        public Form1()
        {
            InitializeComponent();
 
            int iWidth = 100;
            int iHeight = 300;
            if (!cdtInit(ref iWidth, ref iHeight))
                throw new Exception("cards.dll did not load");
        }
 
        private void Form1_Load(object sender, EventArgs e)
        {
 
        }
 
        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            //base.OnPaint(e);
            hdc = e.Graphics.GetHdc();
            Draw();
            e.Graphics.ReleaseHdc(hdc);
 
        }
 
        private void Draw()
        {
            cdtDraw (hdc, 35, 10, 1, 0, 0);
        }
 
 
 
 
    }
}

VB Code:

PInvokeStackImbalance was detected
Message: A call to PInvoke function 'Card Test!Card_Test.Form1::cdtDraw' has unbalanced the stack. 
This is likely because the managed PInvoke signature does not match the unmanaged target signature. 
Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

i figured it out. cdtDraw does not take longs...only ints
