Hi Graham! I very much appreciate you responding to my post, since I often seem to pose questions that don't generate many responses (I was beginning to get a complex).

Anywho, after further research I was able to figure out how to do what I needed to do. ...And the results of my findings are as follows (Peter Criss, drum roll please) :

(1) Your suggestion on using the MouseRow/MouseCol properties work best when you want to grab (read) the data at one particular cell; this is good to know, but not what I wanted to do for this problem. What I wanted to do is find the starting and ending row for the range of rows the user selected. The starting row is given by the Row property and the ending row is given by the RowSel property.

(2)When I say I want to "extract" data, I mean I want to read the data that's in a particular cell so I can stick it in a variable and use it for further processing. To do this, you have to set the Row and Col properties of the grid, then the content is given by the Text property.

My real project is at work, but here at home I slapped together an example that will do what I want:

Code:
'command button clicked after user selects a range of rows ...
Private Sub Command1_Click()

Dim intFirstRowSelected As Integer
Dim intLastRowSelected  As Integer
Dim intX                As Integer
Dim strItem1            As String
Dim strItem2            As String

intFirstRowSelected = MSFlexGrid1.Row
intLastRowSelected = MSFlexGrid1.RowSel

For intX = intFirstRowSelected To intLastRowSelected
    MSFlexGrid1.Row = intX
    MSFlexGrid1.Col = 1
    strItem1 = MSFlexGrid1.Text
    MSFlexGrid1.Col = 2
    strItem2 = MSFlexGrid1.Text
    Debug.Print strItem1, strItem2
Next

End Sub
Again, Graham, I appreciate your efforts and hopefully we both learned something about MSFlexGrid.
