Pulling Files from Web site

Question

I need to be able to run a program that checks a web site for the current version of another program. if the local version is older than the current version i need to replace the exe and dll file with files on the web server. how do I from windows forms pull the files down to the local machine? TIA

You'll need to call Application.DoEvents() before Thread.Sleep(), otherwise the color changes will be cached by GDI+ and won't take effect until the method ends.

Here's how I'd do it. I'm assuming that the buttons all have different colors to start with and you want them to retain their colors when they are in sorted order. You don't need to deal with the case i == 5 as it will never be called:

        public void SwapColor(Button b1, Button b2)

        {

            Color tempColor = b1.BackColor;

            b1.BackColor = b2.BackColor;

            b2.BackColor = tempColor;

        }

        public void BubbleSort(int[] array, int Size)

        {

            int temp;

            for (int pass = 1; pass < Size; pass++)

            {

                for (int i = 0; i < Size - pass; i++)

                {

                    if (array[i] > array[i + 1])

                    {

                        if (i == 0)

                        {

                            SwapColor(btn1, btn2);

                        }

                        if (i == 1)

                        {

                            SwapColor(btn2, btn3);                       

                        }

                        if (i == 2)

                        {

                            SwapColor(btn3, btn4);

                        }

                        if (i == 3)

                        {

                            SwapColor(btn4, btn5);

                        }

                        if (i == 4)

                        {

                            SwapColor(btn5, btn6);

                        }

                       

                        Application.DoEvents();

                        Thread.Sleep(1000); // 2000 is a bit long 

                        temp = array[i];

                        array[i] = array[i + 1];

                        array[i + 1] = temp;

                    }

                }

            }

            a();

        }
