That's a mistake. I did some changes that included renaming the bmp to match the name of the class so they'd match when using the constructor:

[ToolboxBitmap(typeof(NumericTextBox))]
    public class NumericTextBox : TextBox
    {

I've also used:

[ToolboxBitmap(Typeof(NumericTextBox),"EGBClases.NumericTextBox.bmp")]
    public class NumericTextBox : TextBox
    {

And even tried passing the disk path to the file as in:

[ToolboxBitmap(@"C:\Net Proyectos\NetSolucion\EGBClases\Imagenes\NumericTextBox.bmp")]
    public class NumericTextBox : TextBox
    {

But none of them work!
