System.Windows.Forms.ToolStripMenuItem privado aAAToolStripMenuItem;

System.Windows.Forms.ToolStripMenuItem privado bBBToolStripMenuItem;

Botón de anulación privado1_Click(remitente del objeto, EventArgs e)

{

this.menuStrip1 = nuevo System.Windows.Forms.MenuStrip();

this.aAAToolStripMenuItem = nuevo System.Windows.Forms.ToolStripMenuItem(

this.bBBToolStripMenuItem = nuevo System.Windows.Forms.ToolStripMenuItem()

//

// menuStrip1

//

this.menuStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {

this.aAAToolStripMenuItem});

this. menuStrip1.Location = nuevo System.Drawing.Point(0, 0);

this.menuStrip1.Name = "menuStrip1";

this.menuStrip1.Size = nuevo System.Drawing .Size(524, 24);

this.menuStrip1.TabIndex = 3;

this.menuStrip1.Text = "menuStrip1"

//
