VBA to Import Updated Forms in Text Files


Board Regular
Dec 19, 2014
Hi all,

I have an ongoing need to update every form in a database by replacing the production file paths to folders, reports and whatnot with file paths to testing environment folders, reports, etc. I am constantly updating this database, and have been copying my changes from a text editor into every form in a production version of my database. I have been using the text editor's find and replace all function for these strings. My goal is to automate this process, and I have created code that exports all the forms and queries to text files, as well as a PowerShell script that automatically performs the regex replacements I need.

However, my import procedure is not working. Each time it breaks on the .LoadAsText line. I am posting the links I used to create this code. Any help identifying my problem is appreciated.

Note: I also attempted to just write a VBA code within Access that would perform this path replacement for me, but cannot think of an equivalent regex / replace function. I am open to the easiest approach.





And here is my attempt to import:

         Option Compare Database
         Option Explicit
  Private Const VB_MODULE               As Integer = 1
  Private Const VB_CLASS                As Integer = 2
  Private Const VB_FORM                 As Integer = 100
  Private Const EXT_TABLE               As String = ".tbl"
  Private Const EXT_QUERY               As String = ".qry"
  Private Const EXT_MODULE              As String = ".bas"
  Private Const EXT_CLASS               As String = ".cls"
  Private Const EXT_FORM                As String = ".frm"
  'Private Const EXT_FORM                As String = ".vb"
  Private Const CODE_FLD                As String = "code"
  Private Const mblnSave                As Boolean = True               ' False: just generate the script
Public Sub importAllAsText()
            Dim oTable                  As TableDef
            Dim oQuery                  As QueryDef
            Dim oCont                   As Container
            Dim oForm                   As Document
            Dim oModule                 As Object
            Dim FSO                     As Object
            Dim strPath                 As String
            Dim frmPath                As String
            Dim strName                 As String
            Dim frmName                As String
            Dim strFileName             As String
            Dim frmFileName             As String
            Dim tmpName As String
            Dim dlgForms                As FileDialog
            Dim I As Integer: I = 0           ' iterator for file name array
            Dim vFileList() As String ' array for file names
            Dim db As DAO.Database
    'On Error GoTo errHandler
    On Error GoTo 0
    Set db = CurrentDb()
    strPath = CurrentProject.Path
    'Set FSO = CreateObject("Scripting.FileSystemObject")
    Set dlgForms = Application.FileDialog(msoFileDialogFolderPicker)
        With dlgForms
            .Title = "Forms Folder"
            frmPath = .SelectedItems(1)
        End With
    vFileList = GetFileList(frmPath)
    Set oCont = db.Containers("Forms")
    For Each oForm In oCont.Documents
        strName = oForm.Name
        'strFileName = strPath & "\" & strName & EXT_FORM
        For I = LBound(vFileList) To UBound(vFileList)
            If StrComp(strName, Left(vFileList(I), Len(vFileList(I)) - 4), vbTextCompare) = 0 Then
            tmpName = Left(vFileList(I), Len(vFileList(I)) - 4)
            frmFileName = frmPath & "\" & vFileList(I)
                If mblnSave Then Application.LoadFromText acForm, tmpName, frmFileName
                Debug.Print "Application.LoadFromText acForm, """ & vFileList(I) & """, """ & frmFileName & """"
                'GoTo EndLoop
            End If
            I = I + 1
    'If mblnSave Then MsgBox "Files saved in  " & strPath, vbOKOnly, "Export Complete"
    MsgBox "Complete!!"
Exit Sub
    MsgBox "Error " & Err.Number & ": " & Err.Description & vbCrLf
    Resume Next
End Sub

Function GetFileList(pDirPath As String) As Variant
On Error GoTo GetFileList_err
    ' Local constants / variables
    Const cProcName = "GetFileList"
    Dim objFSO As Object
    Dim objFolder As Object
    Dim objFile As Object
    Dim c As Double           ' upper bound for file name array
    Dim I As Double           ' iterator for file name array
    Dim vFileList() As String ' array for file names
    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set objFolder = objFSO.GetFolder(pDirPath)
    c = objFolder.Files.Count
    I = 0
    ReDim vFileList(1 To c)  ' set bounds on file array now we know count
    'Loop through the Files collection
    For Each objFile In objFolder.Files
        'Debug.Print objFile.Name
        I = I + 1
        vFileList(I) = objFile.Name
    'Clean up!
    Set objFolder = Nothing
    Set objFile = Nothing
    Set objFSO = Nothing
    GetFileList = vFileList
    Exit Function
    Debug.Print "Error in ", cProcName, " Err no: ", Err.Number, vbCrLf, "Err Description: ", Err.Description
    Resume Next
End Function

And here is what I've used to export the code to text. I was exporting with the ending ".vb" so my text editor could open up the file with specific formatting. But in this case, I tried both exporting with no file type id as well as ".frm".

Option Explicit

    Dim queryPath As String
    Dim dlgQry As FileDialog
    Dim db As Database
    Dim Qry As QueryDef

    Dim QryText As String

        Set dlgQry = Application.FileDialog(msoFileDialogFolderPicker)
            With dlgQry
                .Title = "Queries Folder"
                queryPath = .SelectedItems(1)
            End With
    Set db = CurrentDb
        QryCount = FreeFile()
            For Each Qry In db.QueryDefs

                QryText = Qry.SQL

                    Open FileName For Output As [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=QryCount]#QryCount[/URL]

                    Print [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=QryCount]#QryCount[/URL] , QryNames, vbNewLine, QryText

    Set db = Nothing
MsgBox "Created source files in " & formPath
MsgBox "Created query files in " & queryPath
End Sub

And here is the powershell code, in case it changes the formatting or encoding of the text files:

$OldString = 'C:\TEST_DB\EXAMPLE\'
 $NewString = 'C:\TEST_DB\NAME_CHANGE\'
 Get-ChildItem C:\DESKTOP\FORMS_PROD\* -recurse |
    Foreach-Object {
        $c = ($_ | Get-Content) 
        $c = $c -replace [RegEx]::Escape($OldString),$NewString
        [IO.File]::WriteAllText($_.FullName, ($c -join "`r`n"))

okay good.
Note that I chose to declare the base_directory as a variant because it's easy and convenient to check its status as Empty. That way I don't have to worry about Null strings or empty strings or blank strings :) As you can see from the sample sub, it works whether or not the calling function expects a string or a variant/string. It also tends to work well in Access generally since we have database data types and vba data types and that can be confusing in its own right.
