Log to file as well as immediate window #215
Conversation
This PR adds functionality to write the same log messages to a file as well as to the VBA immediate window.
For performance reasons the log file is held open unless the project is reset. This commit adds a method to close the log file in order to allow programmatic changes to the log file location.
Public Sub without args are available to run as a macro from the Outlook UI.
Avoid having separate Debug.Print statements in order to print debugging regardless of EnableLogging or file logging.

There was a problem hiding this comment.
The idea here is not to issue excessive numbers of these errors to the immediate window - but upon reflection I am not sure this is such a good idea - or perhaps only if normal EnableLogging is true.

On reflection, I wonder whether the Debug.Print logic should be included in the LogWrite routine. Also, I wonder if we should write the time-stamp to the immediate window also - and if so whether this should be through a separate boolean Public property. |

Hi @Sophist-UK rather than include the file logging with VBA-Web, I'd recommend replacing the current logging with VBA-Log and then creating a standalone file logger that can be used with it. Also, I know you've had some qualms with Example: Dim FileLogger = New FileLog
Logger.LogFile = "..."
WebHelpers.LogInstance = FileLogger
WebHelpers.LogThreshold = 4
' -> CallByName FileLogger, "Log", vbMethod, Level, Message, From |

Here's the related issue: VBA-tools/VBA-Log#1 |

In principle I agree, however VBA-Log uses Application.Run for the callbacks which makes it inelligent but also incompatible with some Office applications. And that would have a knock on effect on VBA-Web compatibility. BUT ... if we can merge the functionality i.e. to provide file logging as a standard part of VBA-Log which does not rely on callbacks, then we could have the best of both worlds. That said, a change to VBA-Log would seem to be something for VBA-Web v5, and o perhaps we can include these changes in the interim in v4. |

BTW, I cannot believe what VBA-Web has enabled me to achieve in Outlook. Happy to tell you offline if you want to correspond privately. (sophist at sodalis dot co dot uk) |
