How to Create Text File for Writing

Creating a Txt-File and write to it

You don't actually have to check if the file exists, as StreamWriter will do that for you.

using (var tw = new StreamWriter(path, true))
{
    tw.WriteLine(TextBox1.Text);
}

public StreamWriter(
string path,
bool append
)

Determines whether data is to be appended to the file. If the file exists and append is false, the file is overwritten. If the file exists and append is true, the data is appended to the file. Otherwise, a new file is created.

How to create text file and write to it in vbscript

Simple Google search like "vbscript create and write to text file" will give you ocean of information on how to tackle this. Anyway here is simplest one to give you kick start.

'~ Create a FileSystemObject
Set objFSO=CreateObject("Scripting.FileSystemObject")

'~ Provide file path
outFile="YouFolderPath\Results.txt"

'~ Setting up file to write
Set objFile = objFSO.CreateTextFile(outFile,True)


strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

Set colFiles = objWMIService.ExecQuery _
    ("Select * from CIM_DataFile Where Extension = 'mdb' OR Extension = 'ldb'")

For Each obj_File in colFiles
    'Wscript.Echo objFile.Name  'Commented out

    '~ Write to file
    objFile.WriteLine obj_File.Name
Next

'~ Close the file
objFile.Close

How to create and write to a txt file using VBA

To elaborate on Ben's answer:

If you add a reference to Microsoft Scripting Runtime and correctly type the variable fso you can take advantage of autocompletion (Intellisense) and discover the other great features of FileSystemObject.

Here is a complete example module:

Option Explicit

' Go to Tools -> References... and check "Microsoft Scripting Runtime" to be able to use
' the FileSystemObject which has many useful features for handling files and folders
Public Sub SaveTextToFile()

    Dim filePath As String
    filePath = "C:\temp\MyTestFile.txt"

    ' The advantage of correctly typing fso as FileSystemObject is to make autocompletion
    ' (Intellisense) work, which helps you avoid typos and lets you discover other useful
    ' methods of the FileSystemObject
    Dim fso As FileSystemObject
    Set fso = New FileSystemObject
    Dim fileStream As TextStream

    ' Here the actual file is created and opened for write access
    Set fileStream = fso.CreateTextFile(filePath)

    ' Write something to the file
    fileStream.WriteLine "something"

    ' Close it, so it is not locked anymore
    fileStream.Close

    ' Here is another great method of the FileSystemObject that checks if a file exists
    If fso.FileExists(filePath) Then
        MsgBox "Yay! The file was created! :D"
    End If

    ' Explicitly setting objects to Nothing should not be necessary in most cases, but if
    ' you're writing macros for Microsoft Access, you may want to uncomment the following
    ' two lines (see https://stackoverflow.com/a/517202/2822719 for details):
    'Set fileStream = Nothing
    'Set fso = Nothing

End Sub

How to create a new text file using Python

Looks like you forgot the mode parameter when calling open, try w:

with open("copy.txt", "w") as file:
    file.write("Your text goes here")

The default value is r and will fail if the file does not exist

'r' open for reading (default)
'w' open for writing, truncating the file first

Other interesting options are

'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists

See Doc for Python2.7 or Python3.6

How do I create a file and write to it?

Note that each of the code samples below may throw IOException. Try/catch/finally blocks have been omitted for brevity. See this tutorial for information about exception handling.

Note that each of the code samples below will overwrite the file if it already exists

Creating a text file:

PrintWriter writer = new PrintWriter("the-file-name.txt", "UTF-8");
writer.println("The first line");
writer.println("The second line");
writer.close();

Creating a binary file:

byte data[] = ...
FileOutputStream out = new FileOutputStream("the-file-name");
out.write(data);
out.close();

Java 7+ users can use the Files class to write to files:

Creating a text file:

List<String> lines = Arrays.asList("The first line", "The second line");
Path file = Paths.get("the-file-name.txt");
Files.write(file, lines, StandardCharsets.UTF_8);
//Files.write(file, lines, StandardCharsets.UTF_8, StandardOpenOption.APPEND);

Creating a binary file:

byte data[] = ...
Path file = Paths.get("the-file-name");
Files.write(file, data);
//Files.write(file, data, StandardOpenOption.APPEND);

How to create txt file

This is how you can create a text file in VB6

Dim iFileNo as Integer
iFileNo = FreeFile
'open the file for writing
Open "C:\Test.txt" For Output As #iFileNo
'please note, if this file already exists it will be overwritten!

'write some example text to the file
Print #iFileNo, "first line of text"
Print #iFileNo, " second line of text"
Print #iFileNo, "" 'blank line
Print #iFileNo, "some more text!"

'close the file (if you dont do this, you wont be able to open it again!)
Close #iFileNo

Creating a text file with java without using absolute path

Your pasted code and the linked question are complete red herrings - they have nothing whatsoever to do with the error you ran into. Also, that protection domain stuff is a hack and you've been told before not to write data files next to your jar files, it's not how OSes (are supposed to) work. Use user.home for this.

There is nothing in this method that explains the question marks - the string, as returned, has plenty of issues (see above), but NOT that it will result in question marks in the output.

Files are fundamentally bytes. Strings are fundamentally characters. Therefore, when you write code that writes a string to a file, some code somewhere is converting chars to bytes.

Make sure the place where that happens includes a charset encoding.

Use the new API (I think you've also been told to do this, by me, in an earlier question of yours) which defaults to UTF-8. Alternatively, specify UTF-8 when you write. Note that the usage of UTF-8 here is about the file name, not the contents of it (as in, if you put persian symbols in the file name, it's not about persian symbols in the contents of the file / in the contents you want to write).

Because you didn't paste the code, I can't give you specific details as there are hundreds of ways to do this, and I do not know which one you used.

To write to a file given a String representing its path:

Path p = Paths.get(completePath);
Files.write("Hello, World!", p);

is all you need. This will write as UTF_8, which can handle persian symbols (because the Files API defaults to UTF-8 if you specify no encoding, unlike e.g. new File, FileOutputStream, FileWriter, etc).

If you're using outdated APIs: new BufferedWriter(new OutputStreamWriter(new FileOutputStream(thePath), StandardCharsets.UTF-8) - but note that this is a resource leak bug unless you add the appropriate try-with-resources.

If you're using FileWriter: FileWriter is broken, never use this class. Use something else.

If you're converting the string on its own, it's str.getBytes(StandardCharsets.UTF_8), not str.getBytes().
