How to search through VBA code files

问题

I just started a job with a new company where previous developers had created many automated tasks. Of course, there is virtually no documentation and I didn't have a chance to work with the previous developer so now I'm trying to sift through all these processes looking for one that modifies some specific files.

I've scripted all the stored procs in SQL and used a search tool and didn't find what I was looking for, so now I am wondering if the process I need is located in one of many Access databases that are used. With SQL Server, it was easy to write a C# app to script the procs so I could search through them, but with Access it looks like I'm confined to opening each db individually to search through the code files.

Is there any way to programatically search through VBA code files?

If your interest is searching code modules in an Access database file, you can use the VBE object model. This sample searches for a word in all the modules of the ActiveVBProject of the current database. If the database includes more than one VBProject, you can enumerate the VBProjects collection and search the projects one at a time by name:

For Each objComponent In Application.VBE.VBProjects(ProjName).VBComponents

Or if you prefer to reference the project by number rather than name, just be aware the numbering starts with 1 rather than 0.

Public Sub findWordInModules(ByVal pSearchWord As String)
    'Dim objComponent As VBComponent
    ' VBComponent requires reference to Microsoft Visual Basic
    ' for Applications Extensibility; use late binding instead:
    Dim objComponent As Object
    Dim strMessage As String
    Dim strModuleList As String

    strModuleList = vbNullString
    For Each objComponent In Application.VBE.ActiveVBProject.VBComponents
        If objComponent.CodeModule.Find(pSearchWord, 1, 1, -1, -1) = True Then
            strModuleList = strModuleList & "; " & objComponent.Name
        End If
    Next objComponent
    strMessage = "Text '" & pSearchWord & "' found in "
    If Len(strModuleList) > 0 Then
        strMessage = strMessage & "modules: " & Mid(strModuleList, 3)
    Else
        strMessage = strMessage & "no modules"
    End If
    Debug.Print strMessage
End Sub

Review the Access help topic for that Find method; you may prefer different options than I used.

If you want to target multiple db files and search the modules in each, you could automate this using the OpenDatabase method. I'll leave the details of that part up to you.

Another option, not previously mentioned - is to just print the Project Code, from the context menu, in the VBA Editor. The steps below, can be modified, to suit applications available, but the result is the same - searchable text.

From the VBA Editor, right click the project name, and click print, from the context menu that appears. Make sure "Code" is checked, and click "OK". The printer can be changed, from the "Setup..." menu, available in the last dialog.

On a side note - stand alone modules, SQL, tables, etc, are available for printing, from the "Database Documenter", in the "Analyze" group, of the "DATABASE TOOLS" tab.

Very useful, for sorting and outlining underlying SQL, of Access queries.

Best to download the free MZ-Tools for VBA and use their search/replace function.

Edit

MZ-Tools for VBA is no longer available. The paid version works with newer office installations.
