Maybe you deleted the warning too, here's the words right off of the editor
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.binary_text = new System.Windows.Forms.TextBox();
... notice the do not modify in the summary.
If you want to have some initialization code do this: Create a new method, call it InitializeThis(), put your code in it, and call it in the constructor right after the initializeComponents call.
