MORE INFORMATION

1. Stop your program if it is currently running.
2. Press the F8 key to go from design mode to break mode.
3. Press CTRL+B to activate the debug window.
4. Enter the following statement and wait for the error message to appear: Error <error-number>
   
   For example, type Error 70, and the following error message appears:
   Permission denied
5. Press F1 to get information from Help on that specific error.
   
   For example, pressing F1 on Error 70 displays the Permission denied page from the Visual Basic Help.

1. Start a new project in Visual Basic. Form1 is created by default.
2. Add a Label control (Label1) and a CommandButton (Command1) to Form1. Set the Label1 Caption property to Status of Error List.
3. Add the following code to the Click event for Command1:

      Dim i As Variant
      Dim buf As String
      Label1.Caption = "Error List Started"
      For i = 1 To &H7FFF
        If Error$(i) <> "User-defined error" Then
          buf = buf & Format$(i, "@@@@ ") & Error$(i) & Chr$(13) & Chr$(10)
        End If
      Next
      ClipBoard.Clear
      ClipBoard.SetText buf
      Label1.Caption = "Error List Complete"
   					

4. On the Run menu, choose Start, or press the F5 key to run the program. Click Command1 and, when the label displays the following error message, then paste the contents of the clipboard into an editor, such as Notepad:
   Error List Complete
