How to hide excel application using C# excel automation?

For Word 2007 automation the following code makes the winword app invisible.

C#

WordApp.Visible = false;

But when i'm using the same logic for Excel 2007 to hide the app, the property

C#

ExcelApp.Visible = false;

does not make it invisible.
Please suggest why this property is not being set to false/ some other way to work around.

VS -2008
.NET - 3.5
Office - 2007 are versions of tech used for working.
OS - Windows 8.

The Visible property of an Excel Application is a bool not a string.
You should use

C#

ExcelApp.Visible=false;

Sorry for that, it is a printing mistake, in code I am using App.Visible = false;

Well that *should* work. However there is a "feature" of excel that if you manually open a spreadsheet then the invisible copy becomes visible - it's not something like that is it?

After a few testing over different OS, I found-
In Windows 7, initially it remains invisible but, after a while sometimes if I refresh(F5) on desktop it becomes visible.
In Windows XP also same as above.
But in Windows 8 it remains visible as soon as application launches.
