vba calculate length of line selected help

I have avba project i am working on which asks the user to select apolyline on the drawing. The code then gets the length of the line but rturns to abiut 6 decimal places.
Question 1.
How do i get it to return the length to 2 decimal places only?
Question 2.
If the user selects anumber (ie 2, 3, 4 etc) from a combobox on a user form in the project, how do i get the length of the line multiplied by the selected number?
I have listed the code i have at present below. I think that is all.

Debug.Print Round(25.345243985744, 2)
or if you're dealing with strings look at the Format function

hth

form in the project, how do i get the length of the line multiplied by the
selected number?

now I'm not sure what you're exactly asking cause I'm sure you know...
dLen = 25.25
lNum = 4
dRes = dLen * lNum
so I think i'm missing something in your question...
