namespace WindowsFormsApplication1
{
    partial class Form1
    {
        /// <summary>
        /// Required designer variable.

            this.num1.Name = "num1";
            this.num1.Size = new System.Drawing.Size(120, 20);
            this.num1.TabIndex = 0;
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(284, 262);

There is only a NumericUpDown control in your form so i'm assuming you want to fetch that value of that control. You'll have to use num1.Value to get it's value.

Try 

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        num1.ValueChanged += new EventHandler(numericUpDown1_ValueChanged);
    }

    void numericUpDown1_ValueChanged(object sender, EventArgs e)
    {
        MessageBox.Show("New value : " +num1.Value);
    }
