I've been having problems extracting the value of a Regex in a String. I have a string with several regex expressions and I need to get the value of each expression's match. The thing is though, it's not returning the last match correctly. For example:
Regex Pattern: I play (S+.*?) and (S+.*?)
String: I play the guitar and the bass The program is returning the value of the first expression as "the guitar" but it's returning the value of the second expression as "the" instead of "the bass".
Does anyone know of a way that you can get the string that is held at this reference point (its the contents of a registry value that corresponds to a string - see this thread for more info [URL]

I am trying to test bit 7 (87654321) in the byte DB2 to check if its true. The below code does not seem to be working:
If DB2 And &H40 = &H40 Then Label1.Visible = True If DB2 And &H40 = &H0 Then Label1.Visible = False TextBox6.Text = Hex(DB2 and &h40)
I do see the value of DB2 changing from &h00 to &h40 in the textbox, but when evaluating in the two if statements, it never evaluates to true (for testing, the only possible values for DB2 right now are &h00 and &h40)
