Debugging using File Operations

The following are some file operations which are useful for debugging. The following examples can be found in the FileOperationForDebugging.vbs file located in the \CodeSamplesPlus folder.

' Creates a specified file and returns a TextStream object that can be used to read from or write to the file.

' Example of usage:

' Set f = CreateFile("d:\emp\beenhere.txt", True)

' f.WriteLine Now

' f.Close

Function CreateFile(sFilename, bOverwrite)

Set fso = CreateObject("Scripting.FileSystemObject")

Set CreateFile = fso.CreateTextFile(sFilename, bOverwrite)

End Function

' Opens a specified file and returns a TextStream object that can be used to read from, write to, or append to the file.

' iomode: 1 - ForReading, 2 - ForWriting, 8 - ForAppending

' Example of usage

' Set f = OpenFile("d:\emp\beenhere.txt", 2, True)

' f.WriteLine Now

' f.Close

Function OpenFile(sFilename, iomode, create)

Set fso = CreateObject("Scripting.FileSystemObject")

Set OpenFile = fso.OpenTextFile(sFilename, iomode, create)

End Function

' Appends a line to a file.

' Example of usage:

' AppendToFile "d:\emp\beenhere.txt", Now

Function AppendToFile(sFilename, sLine)

Const ForAppending = 8

If sFilename = "" Then

sFilename = Environment("SystemTempDir") & "\QTDebug.txt"

End If

Set f = OpenFile(sFilename, ForAppending, True)

f.WriteLine sLine

f.Close

End Function

' Writes a line to a file.

' Destroys the current content of the file .

' Example of usage:

' WriteToFile "d:\emp\beenhere.txt", Now

Function WriteToFile(sFilename, sLine)

Const ForWriting = 2

If sFilename = "" Then

sFilename = Environment("SystemTempDir") & "\QTDebug.txt"

End If

Set f = OpenFile(sFilename, ForWriting, True)

f.WriteLine sLine

f.Close

End Function
