Caching in Forms application
I am wanting to use caching in a Windows Forms app. The help for the Cache

was designed and tested for use in ASP.NET to provide caching for Web
applications. In other types of applications, such as console applications
or Windows Forms applications, ASP.NET caching might not work correctly."

Performing FTP operations in .NET through proxy server

operations should be performed through a proxy and hence the .NET
application should be capable of using a proxy. The proxy server is an
ISA server, which is an HTTP proxy.
The .NET class FTPWebRequest has a property to which the proxy can be

How to scroll a WebBrowser control?
Hi all.
I have a form with a WebBrowser control on it, and I easily get it to
display a certain web page by setting its Url property.
However, the interesting part of the page is out of view, because it is
located much further down the page (below the visible part displayed). So I
need to programatically search for a specific word (or phrase) on the page
and scroll that word (or phra...

papersources and papersizes really slow on some systems.
On some systems, particularly Vista x64 systems, it takes forever (5 to 15
seconds if compiled for x64, 10-20 seconds if compiled for x86) to enumerate
either the papersources or papersizes collection of a printersettings object.
Almost all of that time is spent before the first iteration, that is, I
guess it is setting up the enumerator. Once into the for loop, each
subsequent iterati...

Why is my Console Application limiting itself to half the screen?
I have a Console Application, and when I do a "Start Without Debugging" to
test it, everything works, but it will not allow me to make the window wider
than half my screen. Even if I maximize it, it takes the full height, but
only half the width. This is very annoying, because sometimes lines are
longer than half the screen. Why is this, and is there any way to allow me
to make it take u...
