Hi all,

With your help I have a perfectly working console application.
Now I need to do it a bit more flexible.
So far I have the file paths for all files involved in the applications execution hardcoded.I need to be able to execute the console application from anywhere. i.e the file paths to change dynamically .Meaning to be able to pass the input file names , output file names for the application fro cmd prompt.Is that possible.
I am posting the code :

Imports System
Imports System.IO
Imports System.Xml

Module Module1
    Public Sub ImportXML(ByVal FileName As String, ByRef Names() As String, _
 ByRef CountStart() As Integer, ByRef CountEnd() As Integer)
        Dim FStream As FileStream
        Dim XReader As System.Xml.XmlReader
        Dim XNav As XPath.XPathNavigator
        Dim XDoc As XPath.XPathDocument
        Dim XIter As XPath.XPathNodeIterator
        Dim TempStr As String
        Dim TempInt As Integer
        Dim TempCount As Integer

        TempCount = 0
        FStream = New FileStream(FileName, FileMode.Open, FileAccess.Read)
        XReader = New Xml.XmlTextReader(FStream)
        XDoc = New XPath.XPathDocument(XReader)
        XNav = XDoc.CreateNavigator()

        XIter = XNav.Select("descendant::Strings/String")
        While XIter.MoveNext
            ReDim Preserve Names(TempCount)
            ReDim Preserve CountStart(TempCount)
            ReDim Preserve CountEnd(TempCount)
            ' Name    
            TempStr = XIter.Current.SelectSingleNode("descendant::Name").Value
            Names(TempCount) = TempStr
            ' CountStartPosition    
            TempStr = XIter.Current.SelectSingleNode("descendant::CountStartPosition").Value
            If Integer.TryParse(TempStr, TempInt) Then
                CountStart(TempCount) = TempInt

                CountStart(TempCount) = -1
                ' -1 indicates invalid value    
            End If
            ' CountEndPosition    
            TempStr = XIter.Current.SelectSingleNode("descendant::CountEndPosition").Value
            If Integer.TryParse(TempStr, TempInt) Then
                CountEnd(TempCount) = TempInt
                CountEnd(TempCount) = -1
                ' -1 indicates invalid value    
            End If
            TempCount += 1

        End While


    End Sub

    Public Function MatchString(ByVal OneLine As String, ByVal StringToMatch As String, ByVal StartPos As Integer, ByVal EndPos As Integer) As Boolean
        If String.IsNullOrEmpty(StringToMatch) OrElse String.IsNullOrEmpty(OneLine) Then

            Return False
        End If
        If StartPos < 0 OrElse StartPos >= EndPos Then

            Return False
        End If
        If StringToMatch.Length <> ((EndPos - StartPos) + 1) Then
            Return False
        End If
        If StartPos >= OneLine.Length OrElse EndPos > OneLine.Length Then
            Return False
        End If
        If String.Compare(OneLine.Substring(StartPos, (EndPos - StartPos) + 1), StringToMatch, True) = 0 Then

            Return True
           End If

            ' No match    
            Return False
        End If

    End Function


    Sub Main()

        Dim Names(0) As String
        Dim CountStart(0) As Integer
        Dim CountEnd(0) As Integer

        ImportXML("FilePath.xml", Names, CountStart, CountEnd)

        Console.Write("Reading Started")

        Dim FileToSplit As FileStream
            FileToSplit = New FileStream("C:\FileToSplit.txt", FileMode.Open)
        Catch ex As Exception
            'Couldn`t find the input file.Please check if the input file exists!
            Exit Sub
        End Try

        Dim stream As New StreamReader(FileToSplit)
        stream.BaseStream.Seek(0, SeekOrigin.Begin)

        Dim FileMatch As FileStream
            FileMatch = New FileStream("C:\FileMatch.txt", FileMode.OpenOrCreate)
        Catch ex As Exception
            'Couldn't open the output file.
            Exit Sub
        End Try
        Dim filetosplitstream As New StreamWriter(FileMatch)


        Dim i As Integer 
        ' Loop counter
        Dim bMatch As Boolean
        Dim Line As String

        ' Indicates if we found a match
        While stream.Peek() > -1
            Line = Console.ReadLine()
            bMatch = False
            ' Loop xml file  
            For i = 0 To Names.GetUpperBound(0)
                ' Check for a match   
                If MatchString(Line, Names(i), CountStart(i), CountEnd(i)) Then
                    ' It's a match. Set the flag and exit inner loop      
                    bMatch = True
                    Exit For
                End If
            Next i
            If bMatch Then
                ' We had a match so write the line to the output stream    

            End If
        End While
        MsgBox("Finished Writing the File")
    End Sub

End Module

Ok so bits that are in green I need to be able to pass from command line , like
applicationname <filetosplit> <xml > <filematch>
I read that I can use GetFullPath method , but I don`t think that this will work here .
I will have to be able to change name of the input file, output file and xml file name.Structure of the all Three will remain the same.
If anyone can give a clue how that can be done will be greatly appreaciated.
Would that be a kind of function or is there any orher way of declaring the files paths to be read from the cmd line each time?
Thanks in advance:)
