Redirecting Console.Write
I wrote the below-mentioned code from an amalgamation of c# tutorials about redirecting Console.Write or Console.WriteLine to a textbox text field. I realized this was bad since if I invoke any kind of .Close() method will erase the textbox which is the opposite of what I want to do.
Imports System.Text
Imports System.IO
Namespace ConsoleRedirection
Public Class TextBoxStreamWriter
Inherits TextWriter
Private _output As TextBox = Nothing
Public Sub New(ByVal output As TextBox)
_output = output
End Sub
Public Overrides Sub WriteLine(ByVal value As String)
MyBase.WriteLine(value)
_output.AppendText(String.Format("[{0}] {1}" + vbNewLine, DateTime.Now, value.ToString()))
End Sub
Public Overrides ReadOnly Property Encoding As Encoding
Get
Return System.Text.Encoding.UTF8
End Get
End Property
End Class
End Namespace
Is there anyway, besides loading a text file, that I can have all Console output redirected to either a textbox?
To answer a question from comments. (This code was originally found here: https://saezndaree.wordpress.com/2009/03/29/how-to-redirect-the-consoles-output-to-a-textbox-in-c/... But was converted over to VB)
In a separate form, the code is invoked by declaring a TextWriter.
Private _writer As TextWriter = New TextBoxStreamWriter(frmDebugLog.txtDebugLog)
Then as part of the .Load of a parent form:
Console.SetOut(_writer)
On a later portion of the form, the frmDebugLog is invoked by using frmDebugLog.Show()
When that window, frmDebugLog, is closed... that form and its textbox contents are discarded.

So, the title mentions aDataTablewhile the question mentions aTextBoxor aDataGridView. You might want to proof-read your questions before submitting. Regardless, you can put whatever you want in that overriddenWriteLinemethod. If you want to write to aDataTablethen write to aDataTable. If you want to write to aDataGridViewthen do so. Just put whatever code you want executed in thatWriteLinemethod. If you want to be able to write to different destinations then you could have multiple constructors.

@jmcilhinney I thought I edited that out, noted. Another idea I had, previously, was to redirect it to a datatable. Problem was, it's the same problem... I close the object, the table gets wiped. (That and I got lost on how to set up the table in the first place.) So I focused on the textbox still.

It appears that you're using the default instance and so only ever one instance at a time. In that case, this will do the job:
Private Shared txtDebugLogText As String
Public Sub New()
' This call is required by the designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
txtDebugLog.Text = txtDebugLogText
End Sub
Protected Overrides Sub OnFormClosed(e As FormClosedEventArgs)
txtDebugLogText = txtDebugLog.Text
MyBase.OnFormClosed(e)
End Sub
By using a Shared field, you keep everything within the one class. The current value of that field is loaded into the TextBox first whenever a new instance is created and the text in the current TextBox is persisted to that field whenever an instance is destroyed.
