Do not presume to know the mind of someone asking an apparently stupid question. There is a school of thought that says that there are no stupid questions, only stupid answers.

I beg to differ about:
- there being no good reason to act differently.
- there being no good way to tell the difference.

Now, why would I want Print Preview to be different? Because my graphics lines @ 1200 dpi are TOO THIN to show even at 500% Zoom ! So I want to use thicker lines in print preview (and it's also quicker generating a page of bitmapped graphics @ 200dpi rather than 1200dpi).

I don't like flags. The idea of OO stuff is encapsulation.

Good News:
The PrintDocument passed as object sender to XX_PrintPage contains a member 'PrintController' which has a member 'underlyingController' which has a type of {System.Drawing.Printing.PreviewPrintController} or {System.Drawing.Printing.StandardPrintController}.

Bad News:
This is supposed to be hidden from you (thank you Bill and your people who can't think outside the square and mutter "Why would you do anything different").

Good News:
Use Reflection!
//using System.Reflection;
PrintDocument PD = sender as PrintDocument;
PrintControllerWithStatusDialog PC = PD.PrintController as PrintControllerWithStatusDialog;
FieldInfo FI = PC.GetType().GetField("underlyingController", BindingFlags.NonPublic | BindingFlags.Instance);
PreviewPrintController PPC = FI.GetValue(PC) as PreviewPrintController;

Now, if PPC is not null, it's PrintPreview.
If PPC is null, it's not PrintPreview.

Bad News:
It's ugly, brittle, hardly polymorphic, uses undocumented features of dotNet Framework and might stop working in a future release.
Maybe it's not a good way, but it's better than no way.

Good News:
It works for me, and I hope it does for you, too.

Brewman
