ADDED. Yes, in essence I want to serialize classes and types.

I feel like what you kind of want is to serialize all your classes as
they are to an XML file? I know this function exists in other
languages but VBA might not have it as it is. (I'm sure you could
force something) – Brad
#Brad, yes, exactly, as one of possible ways – nikaan
Assuming that this method does not exist for VBA (although it is available for VB.NET or VB 2005: http://support.microsoft.com/kb/315703), I would probably try to make a simulation: Write the state of each object / variable (of those needed) to a txt file by using FSO.
I don't know if this is feasible for your project though and I probably wouldn't like to do this with pleasure for a huge amount of code.
dim sFile As string
Dim FSO As FileSystemObject
Dim FSOFile As TextStream
sFile = "U:/Log.txt"
Set FSO = New FileSystemObject
Set FSOFile = FSO.OpenTextFile(sFile, 2, True)
FSOFile.writeline (<Descriptions+Property/variable value>)
FSOFile.Close
set FSO = nothing
Depending on how well you input descriptions (eg. inlcuding boolean values for successful instantiation of objects, etc...), you may be able to see what has happened behind the screen up to the point where your application crashed...
I don't know if this answers your question, as I'm a little bit doubting about what you refer to with "fields" (comments).

When being the owner of a VBA project, you can create a sub routine that exports all the modules in your currenct project.
This link provides the code:
http://edndoc.esri.com/arcobjects/9.0/Samples/Application_Framework/ExportVBACode.htm
For the purpose as you describe it, I don't see a reason to do this.
Personally I would use a lame trick like this one:
Option Explicit
Sub Save_File()
Dim sCur_Path As String
Dim sCopied_Path As String
Application.DisplayAlerts = False
Application.ScreenUpdating = False
sCur_Path = ThisWorkbook.FullName
sCopied_Path = "U:/Copied_New.xlsm"
ThisWorkbook.SaveAs sCopied_Path
ThisWorkbook.SaveAs sCur_Path
End Sub

Can a Variable be stored in an Excel File that can not be accessed through Excel

I just discovered that in MS Word it is possible to store a Variable in a MS Word File that can not be accessed through the regular interface when running Microsoft Word.
Sub SetMyVariable()
Dim VARNAME As String
VARNAME = "HiddenVar"
ActiveDocument.Variables.Add VARNAME, "My special info"
End Sub
This gets saved in the XML Schema under word\settings.xml
I have tried using the ThisWorkbook Object in Excel, but it doesn't seem to have a Variable object that can be added like in word.
I want to know if there is something similar in Excel to store information/varialbes that get saved with the file.
PS: the closest thing I can think of (and use in codig) is a hidden named range.
You can try with the CustomXMLParts property of the Workbook which from the link seems a generic feature of Office products and available in Excel. Given you noted that a user would have to manually inspect the XML within the unzipped xlsx files then this seems to map to the Word Variables feature. The code sample just substitutes ThisWorkbook for ActiveDocument:
Option Explicit
Sub TextXMLPart()
Dim objXMLPart As CustomXMLPart
'add
Set objXMLPart = ThisWorkbook.CustomXMLParts.Add("<foo>bar</foo>")
'inspect
For Each objXMLPart In ThisWorkbook.CustomXMLParts
Debug.Print objXMLPart.XML
Next objXMLPart
End Sub
The accepted answer to this question (which focuses on Excel and vsto) states that:
Custom XML parts For an application-level add in, this is my preferred method of storing any application data that needs to be persisted in a saved xls file without ever being visible to the user.

Use DBEngine with Run-time Access

i try to connect my xls with access database. Below code work greate when i have installed full access program on my machine. Problem is when i try tu use it on machine what have only installed Run-time version of access.
I have use this references:
Visual Basic For Applications
Microsoft Excel 14.0 Object Library
OLE Automation
Microsoft Office 14.0 Object Library
Microsoft Forms 2.0 Object Library
When i try to run below code i get error: ActiveX component can't create object or return reference to this object (Error 429)
Sub mcGetPromoFromDB()
Application.ScreenUpdating = False
Dim daoDB As DAO.Database
Dim daoQueryDef As DAO.QueryDef
Dim daoRcd As DAO.Recordset
'Error on line below
Set daoDB = Application.DBEngine.OpenDatabase("K:\DR04\Groups\Functional\DC_Magazyn\Sekcja_Kontroli_Magazynu\Layout\dbDDPiZ.accdb")
Set daoRcd = daoDB.OpenRecordset("kwPromoIDX", dbOpenDynaset)
Dim tempTab() As Variant
For Each Article In collecArticle
daoRcd.FindNext "IDX = " & Article.Index
Article.PromoName = daoRcd.Fields(1).Value
Article.PromoEnd = "T" & Format(daoRcd.Fields(2).Value, "ww", vbMonday, vbUseSystem)
Next
Application.ScreenUpdating = True
End Sub
Is IDX an indexed field?
Is kwPromoIDX optimized for this specific purpose? I mean does it only contain the fields required for this update, or are you pulling extra useless fields? Perhaps something like "SELECT IDX, [Field1Name], [Field2Name] FROM kwPromoIDX" would be more efficient.
Since you are only reading the table records, and don't seem to need to actually edit them instead of dbOpenDynaset, use dbOpenSnapshot.
Just throwing out an idea here, you'd have to test to see if it made any difference, but perhaps you could try to reverse your logic. Loop through the recordset 1 by 1 and locate the IDX within your worksheet.
Another thing I've done in the past is use .CopyFromRecordset and copied the entire recordset into a temporary worksheet and done the juggling back and forth entirely within Excel, to eliminate the back and forth.
Lastly, another approach can be to quickly loop through the entire recordset and populate an array, collection, ... and then work with it instead of Access. This way the data is all virtual and you reduce the back and forth with Access.
You'll need to do some testing to see what works best in your situation.

VBA list of filepaths of linked objects in document

I have a number of large Microsoft Word documents with many linked files from many Microsoft Excel spreadsheets. When opening a Word document, even with the 'update linked files at open' option unchecked:
Word still checks each link at its source by opening and closing the relevant excel spreadsheet for each individual link (so for x number of links, even if from the same spreadsheet, Word will open and close the spreadsheet x times). This means opening documents takes a very long time.
I have found that documents open faster if the spreadsheets containing the source of linked objects are already open, so Word doesn't keep opening, closing, reopening them.
So far, the beginnings of a solution I have is to create a list of all the filepaths of the linked objects, done by following VBA code:
Sub TypeArray()
Dim List(), Path As String
Dim i, x As Integer
Dim s As InlineShape
Dim fso As FileSystemObject, ts As TextStream
Set fso = New FileSystemObject
Set ts = fso.OpenTextFile("C:\MyFolder\List.txt", 8, True)
With ts
.WriteLine (ActiveDocument.InlineShapes.Count)
End With
For Each s In ActiveDocument.InlineShapes
Path = s.LinkFormat.SourcePath & "\" _
& s.LinkFormat.SourceName
With ts
.WriteLine (Path)
End With
Next s
End Sub
'--------------------------------------------------------------------------------------
Private Sub WriteStringToFile(pFileName As String, pString As String)
Dim intFileNum As Integer
intFileNum = FreeFile
Open pFileName For Append As intFileNum
Print #intFileNum, pString
Close intFileNum
End Sub
'--------------------------------------------------------------------------------------
Private Sub SendFileToNotePad(pFileName As String)
Dim lngReturn As Long
lngReturn = Shell("NOTEPAD.EXE " & pFileName, vbNormalFocus)
End Sub
which works well, but can only be used after a document is already open, which defeats its purpose.
So, finally, my question(s) are these:
1) Is there a way to run this code (or any better, more efficient code - suggestions are welcome) before opening a Word document and waiting through the long process of checking each link at its source?
2) Is there a way to avoid all this and simply have Word not check the links when it I open a document?
Sorry for the long question, and thank you for the help!
If I am not wrong there should be Document_Open event according to msdn. This should actually be a before open document and should be fired before updating links (at least it in excel it is fired before calculation).
Try opening the files on document open. Then you will face another problem, and so when to close the files, but that is a much easier thing to do. (probably document_close event...)
EDITTED:
As comments state, this is too late. You can create a word opener (as a single app or as an addin). The logic basically is:
'1) on something_open run GetOpenFileName dialog
'2) before opening the real thing, open all files accompanied
'3) open the document itself
'4) close all files
'5) close the opener itself
This is not the most trivial way, but I use this logic for exampe to make sure, that my applications always runs in a fresh copy of excel etc. But I understand that this is a workaround rather then a solution.
If you are still looking for something on this front, I created the following in a combination of VBA and VB.NET (in VS 2010) to show what can be done quite easily using that system. If VB.NET is no use to you, sorry, but there are reasons why I don't really want to spend time on the pure VBA approach.
At present, it is a "console" application which means you'll probably see a box flash up when it runs, but also means that you are more likely to be able to create this app without VS if you absolutely had to (AFAICR the VB.NET /compiler/ is actually free). It just fetches the link info. (i.e. there's currently no facility to modify links).
The overview is that you have a small piece of VBA (say, in your Normal template) and you need an open document. The VBA starts a Windows Shell, runs the VB.NET program and passes it the full path name of the document you want to open.
The VB.NET program opens the .docx (or whatever) and looks at all the Relationships of type "oleObject" that are referenced from the Main document part (so right now, the code ignores headers, footers, footnotes, endnotes and anywhere else you might have a link)
The VB.NET program automates Word (which we know is running) and writes each link URL into a sequence of Document Variables in the active document. These variables are called "Link1", "Link2", etc. If there are no links (I haven't actually tested that path properly) or the program can't find the file, "Link0" should be set to "0". Otherwise it should be set to the link count.
The shell executes synchronously, so your VBA resumes when it's done. Then you either have 0 links, or a set of links that you can process.
The VBA is like this:
Sub getLinkInfo()
' the full path name of the program, quoted if there are any spaces in it
' You would need to modify this
Const theProgram As String = """C:\VBNET\getmaindocumentolelinks.exe"""
' You will need a VBA reference to the "Windows Script Host Object Model"
Dim oShell As WshShell
Set oShell = CreateObject("WScript.Shell")
' plug your document name in here (again, notice the double quotes)
If oShell.Run(theProgram & " ""c:\a\testdocexplorer.docx""", , True) = 0 Then
With ActiveDocument.Variables
For i = 1 To CInt(.Item("Link0").Value)
Debug.Print .Item("Link" & CStr(i))
Next
End With
Else
MsgBox "Attempt to retrieve links failed"
End If
End Sub
For the VB.NET, you would need the Office Open XML SDK (I think it's version 2.5). You need to make references to that, and Microsoft.Office.Interop.Word.
The code is as follows:
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports System.IO
Imports System.Xml
Imports System.Xml.Linq
Imports DocumentFormat.OpenXml.Packaging
Imports Word = Microsoft.Office.Interop.Word
Module Module1
Const OLEOBJECT As String = "http://schemas.openxmlformats.org/officeDocument/2006/relationships/oleObject"
Sub Main()
Dim s() As String = System.Environment.GetCommandLineArgs()
If UBound(s) > 0 Then
Dim wordApp As Word.Application
Try
wordApp = GetObject(, "Word.Application")
Dim targetDoc As Word.Document = wordApp.ActiveDocument
Try
Dim OOXMLDoc As WordprocessingDocument = WordprocessingDocument.Open(path:=s(1), isEditable:=False)
Dim linkUris As IEnumerable(Of System.Uri) = From rel In OOXMLDoc.MainDocumentPart.ExternalRelationships _
Where rel.RelationshipType = OLEOBJECT _
Select rel.Uri
For link As Integer = 0 To linkUris.Count - 1
targetDoc.Variables("Link" & CStr(link + 1)).Value = linkUris(link).ToString
Next
targetDoc.Variables("Link0").Value = CStr(linkUris.Count)
OOXMLDoc.Close()
Catch ex As Exception
targetDoc.Variables("Link0").Value = "0"
End Try
Finally
wordApp = Nothing
End Try
End If
End Sub
End Module
I originally wrote the .NET code as a COM object, which would be slightly easier to use from VBA, but significantly harder to set up on the .NET side and (frankly) much harder to modify & debug as you have constantly to close Word to release the references to the COM DLLs.
If you actually wanted to fix up the LINK paths, as far as I can tell, modifying them in the relationship records is enough to get Word to update the relevant LINK fields when it opens Word, which saves having to modify the XML code for the LINK fields as well. But that's another story...
I just found out that you can set/modify a DelayOleSrvParseDisplayName registry entry and a NoActivateOleLinkObjAtOpen registry entry to modify the global behaviour:
See http://support.microsoft.com/kb/970154
I also found that activedocument.fields can contain links to external objects (in my case, an Excel sheet).
Use this code to parse them:
for each f in activedocument.fields
debug.print f.code
next
And use activedocument.fields(FIELDNUMBER) to select each object, to figure out where it is in the document.
Maybe also activedocument.Variables and activedocument.Hyperlinks can contain links to external objects? (not in my case).

Calling an External VBA from VBScript

I am using a program called mathtype to pull some equation objects out of a word document. I've written code in VBA that works perfectly using their API, but I have to translate it to a VBScript file. I have looked all over google, but have not found any solution on how (If it is even possible) to call a VBA library from VBScript.
VBScript can't see the MathTypeSDK Objects/Functions.
If not possible, how would I encase the macro I need to run in a globally available word file and call it from the VBScript?
Edit: Got it! Unfortunately the approaches below, while helpful, did not work for my situation. I found something closer: Embedding the macro in a global file and calling it through the Word Objects Run command.
objWord.Run "Normal.NewMacros.RunMain"
Here is an approach which might work for you. I tested this simple example.
Class "clsTest" in file "Tester.docm":
Public Sub Hello()
MsgBox "Hello"
End Sub
Class "Instancing" is marked "PublicNotCreatable".
Module in "Tester.docm":
Public Function GetClass() As clsTest
Set GetClass = New clsTest
End Function
In your vbscript:
Dim fPath, fName
fPath = "C:\Documents and Settings\twilliams\Desktop\"
fName = "Tester.docm"
Dim wdApp, o
Set wdApp = CreateObject("word.application")
wdApp.visible=true
wdapp.documents.open fPath & fName
Set o = wdApp.Run("GetClass")
o.Hello
Set o=nothing
Again - I only tested this simple example: you'll have to adapt it to your situation and try it out.
Word-VBA was not made to create reusable libraries, I suppose (for usage in external programs).
One way to reuse existing Word-VBA code is, however, run Word via WScript.Shell.Run using the /m<macroname> command line switch (see http://support.microsoft.com/kb/210565/en-us for details). This, has the restriction that evertime you need to call a specific macro, a Word process is started again, running that macro, and ends afterwards. Means, if you need just one call to your Word.VBA for a specfific task, this may be ok, but if you need a lot of interprocess communication between your VBScript and your VBA macro, you should look for a different solution.

How do I programatically add a reference to a VBA project?

I'm deploying an early bound styled VBA module that needs Scripting.Dictionary and RegExp.
The script, predictably, fails when it runs on another computer.
The user has to go to Tools->Reference in the VBA IDE and add a reference to those two libraries manually to make it work.
Hence lies the problem. Asking the non-technical end user to go to the IDE and manually add references is asking way too much of them.
The other alternative is to rewrite the whole (very long script written by someone else) to use late binding. I rather not take this path if there are other methods.
As an altervative, some people suggest adding a reference programatically like so:
Application.VBE.ActiveVBProject.References.AddFromFile [Path to library]
Is this the correct solution and if so are there any downsides of this strategy?
If not, are there other methods that will to enable the code to remain early bound yet does not require references to be added manually by the user.
Suggestions involving direct calls to the Win32/64 API are also welcome.
Thanks.
In my own limited environment (small # of other people using spreadsheets I develop, relatively standard machine setups), if I create the file and add the references, and then give a copy to someone else, they can open it with no problems and not have to do anything, so keep that in mind with this answer. (I'm wondering why that doesn't work for you.) Also, this was with Excel.
Rather than adding a reference from a file path, you might consider using the GUID property instead.
Here is some code I once used to automatically create references in a newly created workbook. (It's part of a script that would export code, references, and unit tests on worksheets to text for use with Subversion and then later reconstitute the workbook from the text files.) You might find it useful to your situation. (EH and cleanup removed to keep it short...)
'Export refs in existing workbook to text file
Private Sub exportRefs_(srcWbk As Workbook)
Dim fs As FileSystemObject
Set fs = New FileSystemObject
Dim tsout As TextStream
Set tsout = fs.CreateTextFile(fs.BuildPath(getTargetPath_(srcWbk), "refs.refs"))
Dim ref As Reference
For Each ref In Application.ThisWorkbook.VBProject.References
Call tsout.WriteLine(ref.GUID)
Next ref
'<EH + cleanup...>
End Sub
'Add refs to newly created workbook based on previously exported text file
Private Sub importRefs_(wbk As Workbook, path As String)
Dim fs As FileSystemObject
Set fs = New FileSystemObject
Dim tsin As TextStream
Set tsin = fs.OpenTextFile(path)
Dim line As String
Dim ref As Reference
While Not tsin.AtEndOfStream
line = tsin.ReadLine()
Set ref = Nothing
On Error Resume Next
Set ref = wbk.VBProject.References.AddFromGuid(line, 0, 0)
On Error GoTo 0
If ref Is Nothing Then
Debug.Print "add failed: " & line
End If
Wend
'<EH + cleanup...>
End Sub
Like, I said, limited environment, but hopefully it helps.
