Examples

The following code example extends the CreateParams property of a Button derived class. The CreateParams.Style property is changed, which causes the button to display an Icon rather than an Image. This example requires that you have a class that inherits from the Button class.

virtual System::Windows::Forms::CreateParams^ get() override
{
   
   // Extend the CreateParams property of the Button class.
   System::Windows::Forms::CreateParams^ cp = __super::CreateParams;

   // Update the button Style.
   cp->Style |= 0x00000040; // BS_ICON value
   return cp;
}

protected override CreateParams CreateParams
{
    get
    {
        // Extend the CreateParams property of the Button class.
        CreateParams cp = base.CreateParams;
        // Update the button Style.
        cp.Style |= 0x00000040; // BS_ICON value

        return cp;
    }
}
