How to modify text document in VB60

1. How to modify text documents in VB6.0?

In VB6.0, you can use the FileSystemObject object to read and modify text documents. Here's a simple example showing how to read a text file and modify its contents: ```vb Dim fso As Object Dim file As Object Dim content As String Set fso = CreateObject("Scripting.FileSystemObject") Set file = fso.OpenTextFile("C:\example.txt", 1) ' 1 means opening the file in read-only mode content = file.ReadAll file.Close content = Replace(content, "old text", "new text") ' Replace "old text" in the text with "new text" Set file = fso.OpenTextFile("C:\example.txt", 2) ' 2

First, make sure you have added a reference to Microsoft Scripting Runtime in the VB6.0 project. This can be achieved through "Project" -> "References" -> Select "Microsoft Scripting Runtime". This way you can use the functionality provided in that reference.

Private Sub ModifyTextFile(filePath As String)
    Dim fso As New FileSystemObject
    Dim ts As TextStream
    Dim newText As String
    
    Set ts = fso.OpenTextFile(filePath, ForReading) ' 打开文本文件以供读取
    newText = ts.ReadAll ' 读取文本文件的内容到变量中
    ts.Close ' 关闭文件
    
    ' 在文本中进行所需的修改（示例中替换"oldText"为"newText"）
    newText = Replace(newText, "oldText", "newText")
    
    Set ts = fso.OpenTextFile(filePath, ForWriting) ' 重新打开文本文件以供写入
    ts.Write newText ' 写入修改后的内容到文本文件中
    ts.Close ' 关闭文件
End Sub

This code opens a text file through the FileSystemObject object, reads the file content into a variable, modifies it, and then writes it back to the file. Make sure the replacement text matches your needs.

2. Use the content of the VB text box to replace the specified text of Word?

To replace the specified text with the content of the VB text box in Word, you can use the operation of the Word application. The following is a simple example:

Private Sub ReplaceWordText(textBoxContent As String)
    Dim objWord As Object
    Set objWord = CreateObject("Word.Application")
    
    ' 打开Word文档
    objWord.Documents.Open "C:\Path\To\Your\Word\File.docx"
    
    ' 替换Word文档中的指定文字（示例中将"OldText"替换为文本框内容）
    objWord.Selection.Find.Text = "OldText"
    objWord.Selection.Find.Execute
    objWord.Selection = textBoxContent ' 替换为文本框内容
    
    ' 保存并关闭Word文档
    objWord.ActiveDocument.Save
    objWord.Quit
End Sub

This code uses the Selection object of the Word application to find and replace the specified text with the contents of the text box. Please modify the file path, replacement text, etc. according to your needs.
