Question

Does someone know how to write VBA code in outside file, which is “imported” into Excel 2003 VBA macro every time you run this macro in Excel – like self updating code?

The idea is I write code in outside editor (VIm), and every time I start Excel macro, macro checks for newer data, import that code inside if necessary and then run it (may be one or more functions/subs).

The steps are: open Excel, open XLS file, click on the button, the macro starts, checks for newer outside data (code I have written in outside editor), if data is new, delete old code, import outside code and then actually run macro itself.

Anyone?

Found solution (partly from http://www.cpearson.com/excel/vbe.aspx) 10x Scott:

Sub AddOutsideCode()
    Dim VBProjekt As VBIDE.VBProject
    Dim VBKomponenta As VBIDE.VBComponent
    Set VBProjekt = ThisWorkbook.VBProject
    Call DeleteAllButThis(ThisWorkbook, "Fixed")
    Set VBKomponenta = VBProjekt.VBComponents.Import(Filename:="C:\bat\bat.bas")
    VBKomponenta.Name = "OutsideCode"
End Sub

'Delete all modules but named
Private Sub DeleteAllButThis(ByVal wb As Workbook, ByVal CompName As String)
    Application.DisplayAlerts = False
    On Error Resume Next
    For Each komponenta In ThisWorkbook.VBProject.VBComponents
        If komponenta.Name <> CompName Then
            If komponenta.Type = vbext_ct_StdModule Then
                ThisWorkbook.VBProject.VBComponents.Remove komponenta
            End If
        End If
    Next komponenta
    On Error GoTo 0
    Application.DisplayAlerts = True
End Sub

But how to check if the outside code changed or not?
