                    {
                        if (MinVal > c.Location.X)
                        {
                            MinVal = c.Location.X;
                        }
                        if (MaxVal < c.Location.X)
                        {
                            MaxVal = c.Location.X;

int min=0;
int max=0;
foreach (Control c in this.Controls)  
            {  
                if (c.GetType() == typeof(PictureBox))  
                    {
                        if (MinVal > c.Location.X)
                        {
                            MinVal = c.Location.X;
                            continue;
                        }
                        if (MaxVal  < c.Location.X)
                        {
                            MaxVal = c.Location.X;
                            continue;
