Default Works under App but not under Windows service

I have a weard problem, I have created a class and instanciate an object for using his methods... Everything works fine if I use the class under a windows APPLICATION, but when I call the method under a windows service... It's failing...
There must be something wrong. I tried putting some [STAThread] without knowing what it does.
I'm very confused (newbie to .Net also) hey hey !

here's my class code.

using System;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Collections.Generic;
using System.IO;
using System.Diagnostics;
using Cvb;

namespace TestCorrelateClass
    public sealed class MainForm
        public Cvb.Image.IMG cvSourceImage;
        public Cvb.Image.IMG cvLiveImage;
        public Cvb.Minos.TPL cvTemplateImage;
        public double liveHeight;
        public double liveWidth;
        public MainForm()
            System.Drawing.Image objImage = System.Drawing.Image.FromFile("c:\\testok91.jpg");
            liveHeight = objImage.Size.Height;
            liveWidth = objImage.Size.Width;
            bool result = Cvb.Image.LoadImageFile("c:\\testok91.jpg", out cvSourceImage);
            writeLogging("Image loaded Source ");
       public bool testCammoved(int X0, int Y0, int X1, int Y1, int treshOld)
            Utilities.TIMEWATCH timerHandle;
            Cvb.Image.TArea area;
            double stopTime;
            int density = 250 + (treshOld * 75);
            double diffPixels = treshOld * 1.5;
            double xPos, yPos, quality, dX, dY;
