C# Visio drawing control -- Close stencils

[Pradeep]

I am working on Visio drawing control in my application using C#.
There is a button "Open". On clicking this, I want to close all the stencils
which are currently open and then load the stencil "abc.vss".
Please help me out how to implement this in C#

an algorithm to look at, conversion to C# is left as an exercise...

for all open documents {
if upprecase(file extension) = '.vss' {
close document
}
}
active document openStencil("abc.vss")
