Edit Word document in visual basic application

[ACE--]

Hi,

My requirement I need to edit or replace content in the word document every time and save it to another location.
What I wanted is I want to simplify this through vb.net but stuck in somewhere I am doing mistake in the code itself (I am completly newbie).

I have created a form and I have inserted 2 controls i.e. RichTextBox and Button

If I Enter text in Richtextbox like below format word document is generating undesired results.

example:
add1
add2
add3
add4

result: add1 add2 add3 add4 add5

what I want is in what ever way I am giving input in the textbox the same output should be generated in word doc.

below is my faulty code:

Imports System.Runtime.InteropServices
Imports Microsoft.Office.Interop

Public Class Form1

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click



        Dim objWordApp As Word.Application
        objWordApp = New Word.Application
        Dim objDoc As Word.Document
        Dim rng As String

        'Open an existing document.
        objWordApp.Documents.Open("C:\Users\Desktop\Sample.docx")
        objDoc = objWordApp.ActiveDocument

        'Find and replace some text.
        objDoc.Content.Find.Execute(FindText:="<Address>", _
            ReplaceWith:=rng, _
            Replace:=Word.WdReplace.wdReplaceAll)

            'Save and close the document.
            objWordApp.Documents.Item(1).Save()

            objWordApp.Documents.Close(Word.WdSaveOptions.wdDoNotSaveChanges)
            objWordApp.Quit()
            objWordApp = Nothing
    End Sub

End Class

Thanks for everyone's help. :)

Still waiting for the solution.

Try using the & VBNewLine after each word or .Crlf that should do the trick for you.

The following has been tested and should work:

Requires the following:

Add reference to "Microsoft Word xx.x Object Library":

• Click "Project"
• Select "Add Reference"
• Click "COM" tab
• Select "Microsoft Word xx.x Object Library"

Add import statements:

• Imports System.Runtime.InteropServices

• Imports Word = Microsoft.Office.Interop.Word

  Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
  
      'use early binding
      Dim objWordApp As Word.Application = Nothing
  
      Try
  
          objWordApp = New Word.Application
  
          'Open an existing document.
          objWordApp.Documents.Open("C:\Temp\Sample.docx")
  
          'copy data to clipboard
          RichTextBox1.SelectAll()
          RichTextBox1.Copy()
  
          'find <address>
          objWordApp.Selection.Find.Execute("<address>")
  
          'copy richtext from clipboard
          objWordApp.Selection.PasteSpecial(DataType:= Word.WdPasteDataType.wdPasteRTF)
  
          'clear the clipboard
          Clipboard.Clear()
  
          'Save and close the document.
          objWordApp.Documents.Item(1).Save()
          objWordApp.Documents.Close(Word.WdSaveOptions.wdDoNotSaveChanges)
  
      Catch ex As Exception
          MessageBox.Show(ex.Message)
      Finally
  
          'quit Word
          If Not IsNothing(objWordApp) Then
              objWordApp.Quit()
              objWordApp = Nothing
          End If
  
      End Try
  End Sub
  

*Note: The font properties will be transferred from the RichTextBox as well.

Thanks a lot

The following will replace "<address>" with the text contained in RichTextBox1 and save the document as a .pdf file. The original file will be unmodified:

        'use early binding
        Dim objWordApp As Word.Application = Nothing

        Try

            objWordApp = New Word.Application

            'Open an existing document.
            objWordApp.Documents.Open("C:\Temp\Sample.docx")


            'copy data to clipboard
            RichTextBox1.SelectAll()
            RichTextBox1.Copy()

            'find <address>
            objWordApp.Selection.Find.Execute("<address>")

            'copy richtext from clipboard
            objWordApp.Selection.PasteSpecial(DataType:=Word.WdPasteDataType.wdPasteRTF)

            'clear the clipboard
            Clipboard.Clear()

            'save as PDF
            objWordApp.ActiveDocument.SaveAs2("C:\Temp\Sample.pdf", Word.WdSaveFormat.wdFormatPDF)

            'Close the document.
            objWordApp.Documents.Close(Word.WdSaveOptions.wdDoNotSaveChanges)

        Catch ex As Exception
            MessageBox.Show(ex.Message)
        Finally

            'quit Word
            If Not IsNothing(objWordApp) Then
                objWordApp.Quit()
                objWordApp = Nothing
            End If

        End Try

Note: You will need to be using a version of Word that allows a file to be save as ".pdf".
