Hello!
I have some problem with replacing special characther in a Word file(.doc).
In the word file there are 2 field to replace:
- Subject
- Memo

I Have some problem with Memo because the string to replace in it has some vbCrLf.
The string to StringReplace is:
“Line 1
Line 2
Line 3
Line 4”

This is my vb code

Dim StringReplace as string

StringReplace = StringReplace.Replace(vbCrLf, Aspose.Words.ControlChar.LineBreakChar)
doc.Range.Replace("«Memo»", StringReplace, False, False)

Works Great!

I Need to replace vbCrLf with ParagraphBreak and not with LineBreak.
If I write:

StringReplace = StringReplace.Replace(vbCrLf, Aspose.Words.ControlChar.ParagraphBreakChar)
doc.Range.Replace("«Memo»", StringReplace, False, False)

Error: “The replace string cannot contain special or break characters.”

I have word file with text alignment JUSTIFY.
If I replace with LineBreak o Paragraph is not the same.

thanks!

I Tried with Mail Merge but It’s not for my purpose.
In the attached Word File I inserted Field Manually anche not with this procedure https://docs.aspose.com/words/net/mail-merge-template/

I have a lot of documents with field inserted “manually” and I Can’t change all of them.

How Can I Solve?

thanks!

Hi Matteo,

Thanks for being patient. Please use the following code to resolve this issue:

Dim doc As New Document(MyDir & "example.doc")
doc.Range.Replace(New Regex("«Memo»", RegexOptions.None), New MyReplaceEvaluator(), False)
doc.Save(MyDir & "out.doc")

Private Class MyReplaceEvaluator
    Implements IReplacingCallback
    Private Function IReplacingCallback_Replacing(ByVal e As ReplacingArgs) As ReplaceAction Implements IReplacingCallback.Replacing
        Dim StringReplace As String = File.ReadAllText(MyDir & "in.txt")
        StringReplace = StringReplace.Replace(vbCrLf, Aspose.Words.ControlChar.ParagraphBreakChar)
        Dim builder As New DocumentBuilder(e.MatchNode.Document)
        builder.MoveTo(e.MatchNode)
        builder.Write(StringReplace)
        Return ReplaceAction.Replace
    End Function
End Class

Please see attached files. I hope, this helps.
