Regular Expressions are really powerful for identifying areas in strings. Here's a simple example:

 

Dim s As String = tvwBillOfMaterial.SelectedNode.Text
Dim re As New System.Text.RegularExpressions.Regex("\(\d+\.?\d?\d?\d?\d?")  'finds the quantity from the nodes description string
Dim m As System.Text.RegularExpressions.Match = re.Match(s)
Quantity_From_Node_Description = m.ToString

Hope it helps

There are various was to go about this depending on the rigidity of the string.

 

There are two useful functions here; myString.SubString and myString.IndexOf. The former returns part of the string, where you specify the first character to get, and optionally how many characters from that point to get. IndexOf returns the first index of a specific character or string.

 

So, for example, you could Get the first index of "GET", the first index of HTTP, and get the characters between that.

 

edit: or you could use regex :P
