问题
I am trying to develop a VBA procedure for MS Outlook (2016) that removes from selected incoming e-mail a certain (annoying) string.
The string is pretty simple: it is two sentences in German language. So this is theoretically easy to spot and remove. I use the Replace() function for this. This principally works. (See my full procedure below.)
However, I am having problems as the two sentences (the string) are sometimes separated by CRLF (Carriage Return, Line Feed) characters, and these are not always at the same place. - This seems to be the result of these e-mails passing through various devices before they eventually land in my Outlook inbox.
First address the simpler part of the problem
Now before addressing the issue of the CRLF appearing on varying places, I first want to create a procedure that deals with strings with CRLF at fixed positions.
Here is how the source code of such a string would look:
(Screen shot history: I saved the e-mail as .html on my harddisk, then opened the .html file in Notepad++, in order to be able to see the CRLF characters.)
The html tags are not that relevant for me. They can remain in the e-mail. (In fact, the formatting tags vary, too, so it is better to not start tackling them at all.) My only concern is to remove th visible part, i.e. the text "Diese E-Mail kommt... vertrauenswürdig halten".
I tried to catch text with line breaks like this the following way:
strDelete01 = "Diese E-Mail kommt von Personen" & Chr(13) & Chr(10) & "außerhalb der Stadtverwaltung. Klicken Sie nur auf Links oder Dateianhnge," & Chr(13) & Chr(10) & "wenn Sie die Personenn für vertrauenswürdig halten."
i.e. by including the CR LF part as Chr(). Which I expected to work. Somehow, however, it doesn't. My procedure simply does not recognize the string that way, and accordingly does nothing.
My script so far
Here now is the entire procedure:
Public Sub EditBodyCgReplace()
'Declarations
Dim obj As Object
Dim Sel As Outlook.Selection
Dim DoSave As Boolean
Dim NewBody As String
Dim strDelete01 As String
Dim strDelete02 As String
Dim strDelete03 As String
Dim strDelete04 As String
'Fill the variables
strDelete01 = "Diese E-Mail kommt von Personen außerhalb der Stadtverwaltung. Klicken Sie nur auf Links oder Dateianhänge, wenn Sie die Personen für vertrauenswürdig halten."
strDelete02 = "################################################################################"
strDelete03 = <hr>
strDelete04 = "Diese E-Mail kommt von Personen" & Chr(13) & Chr(10) & "außerhalb der Stadtverwaltung. Klicken Sie nur auf Links oder Dateianhnge," & Chr(13) & Chr(10) & "wenn Sie die Personenn für vertrauenswürdig halten."
'Note: I am playing here with various types of strings at once. For example,
'the procedure will also remove <hr> lines and "#####" strings
'Work with it
If TypeOf Application.ActiveWindow Is Outlook.Inspector Then
Set obj = Application.ActiveInspector.CurrentItem
Else
Set Sel = Application.ActiveExplorer.Selection
If Sel.Count Then
Set obj = Sel(1)
DoSave = True
End If
End If
If Not obj Is Nothing Then
NewBody = Replace(obj.HTMLBody, strDelete01, "")
NewBody = Replace(obj.HTMLBody, strDelete02, "")
NewBody = Replace(obj.HTMLBody, strDelete03, "")
NewBody = Replace(obj.HTMLBody, strDelete04, "")
If NewBody <> "" Then
obj.HTMLBody = NewBody
If DoSave Then
obj.Save
End If
End If
End If
End Sub
Question: What can I do to include the CRLF in the search string correctly?
Follow-up question: What can I do to remove such strings with CRLF included in varying places? - Is there a way to use regular expresssions? Is VBA in Outlook strong enough to deal with it? - Idea: if regular expressions work, perhaps the entire CRLF issue is not an issue anymore, as the expression would look something like
"Diese E-Mail kommt von * vertrauenswürdig halten."
and thus include anything - including CRLF - in the middle?
Perhaps important
After doing various experiments I am starting to feel a suspicion growing: Could it be that MS Outlook does not use HTML at all in its e-mails?
I observe that I can practically not address any html code in the obj.HTMLBody. I can address plain text. I cannot address parts of html such as "<hr ", or at least that's what i believe to be observing at the moment. (There was a moment when I could address "<hr>" and thus delete it, but I cannot recreate the conditions where this worked yesterday)
I can, of course, save the e-mails as html files (outside Outlook, just somewhere on my harddisk in a separate folder), and in these files I do see the CRLF and other stuff. But perhaps the e-mails, as long as kept in Outlook itself, are stored using some other code?
So what is this code, and how can I address parts of it for deleting?
回答1:
I will answer your question in parts as I have the spare time. Someone else may get to the important bit before I do.
I have edited your question. I did not understand a couple of sentences so I looked at the source and found my suspicion was correct, you had included less than characters. Stack Overflow permits a limited number of Html tags. Anything else that looks like an Html tag is ignored. I replaced each "<" with "<" so readers could see your Html. I can add an explanation if you do not understand why this works.
You have:
NewBody = Replace(obj.HTMLBody, strDelete01, "")
NewBody = Replace(obj.HTMLBody, strDelete02, "")
NewBody = Replace(obj.HTMLBody, strDelete03, "")
NewBody = Replace(obj.HTMLBody, strDelete04, "")
If NewBody <> "" Then
Each Replace (except the first) overwrites the value of NewBody created by the previous Replace. You seem to think that if strDelete04 is not found, NewBody will be empty. No, if strDelete04 is not found, NewBody will be a copy of obj.HTMLBody.
You need something like:
NewBody = Replace(obj.HTMLBody, strDelete01, "")
NewBody = Replace(NewBody, strDelete02, "")
NewBody = Replace(NewBody, strDelete03, "")
NewBody = Replace(NewBody, strDelete04, "")
If NewBody <> obj.HTMLBody Then
' One or more delete strings found and removed
You say that the CRLFs are not in fixed positions. If so, no simple modification of your code will have the effect you seek. I will show you how to achieve the effect you seek but first I will have to create some emails containing your text so I can test my code.
Part 2
Having looked at your image of the Html more closely, I believe there is a simple solution. The two CRLFs in the text replace spaces. Providing this is always what happens, you can use:
NewBody = Replace(obj.HTMLBody, vbCr & vbLf, " ")
This would remove any CRLF present wherever it appeared within the Html. It would not matter if there were extra CRLFs because any string of whitespace characters (which includes CR and LF) in an Html document is replaced by a single space when the document is displayed.
You finish the removal of the unwanted text with:
Dim strDelete = "Diese E-Mail kommt von Personen außerhalb " & _
"der Stadtverwaltung. Klicken Sie nur auf " & _
"Links oder Dateianhänge, wenn Sie die Personen " & _
"für vertrauenswürdig halten."
NewBody = Replace(NewBody, strDelete, "")
If the above does not work, you need a more convenient diagnostic technique. Saving the entire email as Html may be easy but you cannot be quite sure how the result differs from what a VBA macro would see. You wonder if Outlook stores emails in a format other than Html. I cannot imagine why Outlook would convert the incoming SMTP message to some secret format and then convert it back when the user wishes to view it. If Outlook does have a secret format, it is totally hidden from the VBA programmer.
The following is a simple version of the diagnostic tool I use. If you need something more advanced, I can provide it but let us try this first.
Copy the code below to an Outlook module. Select one of these emails and then run macro DsplHtmlBodyFromSelectedEmails. The entire Html body of the email will be output to the Immediate Window in a readable format. I believe I have included all the subroutines called by the macro. I apologise in advance if I have not. If you get a message about an undefined routine, let me know and I will add it to the answer.
Sub DsplHtmlBodyFromSelectedEmails()
' Select one or emails then run this macro. For each selected email, the Received Time, the Subject and the Html body are output to the Immediate Window. Note: the Immediate Window can only display about 200 lines before
The older lines are lost.

My full diagnostic routine
The subroutine InvestigateEmails() will output to either the Immediate Window or a file on the desktop. The Immediate Window is usually the more convenient but has a limit of about 200 lines. So if the output is likely to be over 200 lines, output must be to a file. If output is less than 200 lines, the choice is yours.
For output to the Immediate Window, review subroutine OutSomeProperties. Add any properties that you wish to see but are missing. Consider removing any properties not currently required. Check that #Const Selected = True.
For output to a file, review subroutine OutAllProperties. More correctly this should be “all properties of which I am aware and have ever been interested in.” You may wish to check that all the properties of interest to you are included. I recommend not removing any existing properties. Check that #Const Selected = False.
Select the emails whose properties you wish to see. Run subroutine InvestigateEmails()
This code uses conditional compiling which will be confusing to a programmer not familiar with this technique. Either research conditional compiling or accept that it is doing something useful that you do not need to understand.
