Simple DTE macros-accelerator c/cpp - h navigation

Introduction

How many times c/c++ programmer swaps between source and header files? Hundreds times per a day! Simple macros in DTE essentially accelerates swapping action.
Create new module, or use existing one, in my case "CommonMacros". To convenience, it is necessary link up this macros to hot key, see picture.

 

Macros code

    
Option Explicit On 
Imports EnvDTE

Public Module CommonMacros
    Sub SourceHeaderJumper()
        'splitted file name
        Dim SArr As System.Array
        'new filename generated by macros
        Dim NewFN As String
        'file name base (without extention)
        Dim FNBase As String
        'file extention
        Dim Ext As String
        'simple counter
        Dim i As Integer

        If DTE.ActiveDocument() Is Nothing Then
            Exit Sub
        End If
        SArr = DTE.ActiveDocument().Name().Split(".")
        'has file extention?
        If (SArr.GetLength(0) < 2) Then
            Exit Sub
        End If

        'file name base
        FNBase = DTE.ActiveDocument().Path()
        For i = 0 To SArr.GetLength(0) - 2
            FNBase = FNBase + SArr(i) + "."
        Next

        'file extention
        Ext = System.Convert.ToString(SArr(SArr.GetLength(0) - 1)).ToLower()

        'business logic
        If (Ext = "cpp") Or (Ext = "c") Then
            NewFN = FNBase + "h"
        Else
            If Ext = "h" Then
                NewFN = FNBase + "cpp"
                If Not System.IO.File.Exists(NewFN) Then
                    NewFN = FNBase + "c"
                End If
            End If
        End If

        'if you don't want add file to tabs uncomment next line
        'DTE.ActiveDocument().Close()

        'opens needed file
        If System.IO.File.Exists(NewFN) Then
            DTE.ItemOperations.OpenFile(NewFN)
        End If
    End Sub

End Module

Try this feature, this macros will save hours of you time during programming from month to month.
