Datalog 2.0.0

This package contains helper methods for writing log of data.

After initialization

SetRootFolder(sRootFolder)
new Datalog(sRootFolder, sSubfolder)

sRootFolder must exists, sSubfolder would be created on first write.

you probably would use only these methods:

AppendLogYearly(dataToAppend As String)		// append to file: root\YYYY.txt
AppendLogMonthly(dataToAppend As String)	// append to file: root\YYYY\YYYY.MM.txt
AppendLogDaily(dataToAppend As String)		// append to file: root\YYYY\MM\YYYY.MM.dd.txt
AppendLogDailyWithTime(dataToAppend As String)	// append to file: root\YYYY\MM\YYYY.MM.dd.HH.mm.txt

But you can also use "more internal" methods:

GetLogFileYearly(Optional sBaseName As String = "", Optional sExtension As String = ".txt") As String
GetLogFileMonthly(Optional sBaseName As String = "", Optional sExtension As String = ".txt") As String
GetLogFileDaily(Optional sBaseName As String = "", Optional sExtension As String = ".txt") As String
GetLogFileDailyWithTime(Optional sBaseName As String = "", Optional sExtension As String = ".txt") As String

All above methods returns file pathnames with filename constructed from sBaseName concatenated with appropriate date part and extension, in proper subfolder inside Datalog's root.

And, if you want to iterate directories in log folders:

GetLogFolderYear() As String	// root\YYYY
GetLogFolderMonth() As String	// root\YYYY\MM

For .Net Standard 2.0 and above, you have additional constructors:

New(specialFolder As Environment.SpecialFolder, Optional sSubfolder As String = "Datalog") // in this specialfolder, folder named as application would be created
New(folderType As DatalogFolder, Optional sSubfolder As String = "Datalog")	// Local or Roam, works also in UWP
New(Optional sSubfolder As String = "Datalog")	// same as New(DatalogFolder.Local, sSubfolder)

and also one utility method:

static GetAppName As String
