Dim success As Boolean
success = False

Dim sb As New Chilkat.StringBuilder
success = sb.Append("www.chilkatsoft.com")

// The GetBefore method returns the contents of the string up to but not including
// the marker string.  If the remove flag is True, then both the returned string AND
// the marker are removed.
Dim removeFlag As Boolean
removeFlag = False
Dim marker As String
marker = "."
Dim substr As String
substr = sb.GetBefore(marker,removeFlag)
System.DebugLog("substr = " + substr)
System.DebugLog("sb contains: " + sb.GetAsString())

// Output:
// substr = www
// sb contains: www.chilkatsoft.com

removeFlag = True
substr = sb.GetBefore(marker,removeFlag)
System.DebugLog("substr = " + substr)
System.DebugLog("sb contains: " + sb.GetAsString())

// Output:
// substr = www
// sb contains: chilkatsoft.com

// If the marker is not found, and the removeFlag is True,
// then the entire string is returned and the sb is cleared.
// For example:
sb.Clear 
success = sb.Append("111--222--333--444")
marker = "--"
removeFlag = True
While (sb.Length > 0)
    substr = sb.GetBefore(marker,removeFlag)
    System.DebugLog("substr = " + substr + ", sb contains: " + sb.GetAsString())

// Output is:
// substr = 111, sb contains: 222--333--444
// substr = 222, sb contains: 333--444
// substr = 333, sb contains: 444
// substr = 444, sb contains:
