Experts, I received some help previously on this topic for another project at Listview Comparer Help.

This worked fine for that particular project, but in a new project that i am working on it does not sort currency properly when there is a wide range of values.

In the attached screen shot i have show what it does with the currencies.

It's comparing by a string rather than by decimal.  

Update your code to ignore the $.

string_x = item_x.SubItems(m_ColumnNumber).Text.Replace("$","")

string_y = item_y.SubItems(m_ColumnNumber).Text.Replace("$","")

I tried this and it does the same thing.
If Decimal.TryParse(Replace(string_x, "$", ""), flags, Nothing, dec_x) And Decimal.TryParse(Replace(string_y, "$", ""), flags, Nothing, dec_y) Then

With the code the way it was to start with, at the break point I can see that the value of dec_x and dec_y are in fact decimal values.

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

Are you using a string format to set the currency?  What if you take that out?  Does it work?

I am using formatCurrency for the item in that column.
lstItem.SubItems.Add(FormatCurrency(reader.Item("IDTCost"), 2))

When i take it out it sorts properly.
I dont know why it is not working the way it is setup already. The TryParse is working using the flags and dec_x and dec_y are converted to decimal properly.

Add this to your flags:

'... = the other globalizations you already have.  Add AllowThousands at the end.

flags = ... OR ... OR System.Globalization.NumberStyles.AllowThousands
