How to pass data in the_widget()

I opend a thread, which was already closed by the community.

I want to pass data by using the_widget() function of wordpress. For example in the 404.php file.

Normally you are able to use

<?php the_widget($widget, $instance, $args); ?>

I tried it this way and my widget comes only with the default settings, which i insert in the get_widget_form(). If i use the SiteBuilder, everything works like a charm!

But not when i tried to insert the widget in a site without a SiteBuilder.

It’s clear to me how to pass data, but i want to use the widgets also in areas where a SiteBuilder is not available.
