Read All Text From a File

There are a number of ways to read all content from a text file. The function below uses only VB6's features to do that.

Public Function ReadAll(ByVal FilePath As String) As String
Dim FileNumber As Long
Dim Result     As String
    If FilePath  "" Then
        If Dir(FilePath)  "" Then
            FileNumber = FreeFile
            Open FilePath For Input As FileNumber
            On Error GoTo Trap
            Result = Input(LOF(FileNumber), FileNumber)
            On Error GoTo 0
            Close FileNumber
        End If
    End If

    ReadAll = Result
    Exit Function

Trap:
    Close FileNumber
    FileNumber = FreeFile
    Open FilePath For Binary Access Read As FileNumber
    Result = Space(LOF(FileNumber))
    Get #FileNumber, , Result
    Resume Next
End Function
