If you want to set transparency of a custom mouse cursor bitmap 'on the fly' you may find this function helpful. It uses a color matrix to set the amount of transparency to any given bitmap and will return the modified one. To have just a touch of transparency the TranspFactor should be between 225 and 245, just try it out. (You need to import System.Drawing and System.Drawing.Imaging)

public static Bitmap GetBMPTransparent(Bitmap bmp, int TranspFactor)

{

Bitmap transpBmp = new Bitmap(bmp.Width, bmp.Height);
using (ImageAttributes attr = new ImageAttributes()) {
    ColorMatrix matrix = new ColorMatrix { Matrix33 = Convert.ToSingle(TranspFactor / 255) };
    attr.SetColorMatrix(matrix);
    using (Graphics g = Graphics.FromImage(transpBmp)) {
        g.DrawImage(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height), 0, 0, bmp.Width, bmp.Height, GraphicsUnit.Pixel, attr);
    }
}
return transpBmp;

}
