your particular code sample is too complex to be answered here. We can only comment on particular code snippets.

BUT when you call ShowDialog(), you basically hand over control to the form. Whatever you want to change must now occur from "inside" the form, either event driven (i.e. timer), or from logic inside your form. In addition, to actually display UI changes, you may also have to refresh the UI elements to give them a chance to redraw.

It may be much easier for you to use WPF, depending on the .NET framework version your systems support.
