Structure and Format of Module

Ok, I don't need help with figuring out the ID3 stuff anymore, but I'm trying to put everything in a module so it's less messy. The part I'm having trouble with is setting it up to where I can get information like this:

VB Code:

with id3info
text1.text = RTrim(getid3info.Album)

It should be easy to find my error just by looking at my code in the module, so I'll just paste it here:

VB Code:

'This module is used to read and write to ID3v1.1 tags.
 
Public Type ID3info
    filename As String
    Hastag As Boolean
    Tag As String * 3
    songname As String * 30
    artist As String * 30
    album As String * 30
    year As String * 4
    comment As String * 28
    Null As Byte
    track As Byte
    genre As Byte
End Type
 
Public Matrix
 
 
 
 
Public Function GetID3info()
    Open filename For Binary Access Read As #1
    Get #1, FileLen(filename) - 127, Tag
    If Not Tag = "TAG" Then
    Close #1
    Hastag = False
        Exit Function
        End If
        Hastag = True
    filename = filename
    Get #1, , songname
    Get #1, , artist
    Get #1, , album
    Get #1, , year
    Get #1, , comment
    Get #1, , track
    Get #1, , genre
    Close #1
End Function
 
Public Function WriteID3info()
 
    Open filename For Binary Access Write As #1
        Seek #1, FileLen(filename) - 127
        Put #1, , Tag
        Put #1, , songname
        Put #1, , artist
        Put #1, , album
        Put #1, , year
        Put #1, , comment
        Put #1, , Null
        Put #1, , track
        Put #1, , genre
    Close #1
End Function
    
    With GetID3info
        songname = .songname
        artist = .artist
        album = .album
        year = .year

Any help appreciated.

im not sure what your question was. one thing i notice is your udt of the tag. The id3 tag v1.1 layout is


Public Type Tag
Tag As String * 3
SongName As String * 30
Artist As String * 30
Album As String * 30
Year As String * 4
Comment As String * 30
Genre As String * 1
End Type

also, you dont need to open for binary comparison or use get and puts. try insted to use text streams. something like this

dim FSO as new Filesystemobject
dim TS as Textstream
dim hFile as file
dim Song as string

set TS = FSO.opentextfile(MyFile, ForReading)
set hFile = FSO.Getfile(filepath)

Song = TS.Read(hFile.Size - 128)
If TS.Read(3) = "TAG" Then
With ID3Tag
.Tag = "TAG"
.SongName = TS.Read(30)
.Artist = TS.Read(30)
.Album = TS.Read(30)
.Year = TS.Read(4)
.Comment = TS.Read(30)
.Genre = TS.Read(1)
End With

you can also do the eqivilent with the ts.write to write the changes to the tag.

something you MUST consider. every id3tag editor ive ever crossed is always done wrong. if you change the id3 tag, you should overwrite the old one. no one ever does, and so when they change it. their song file (mp3. wav) gets 128 bytes bigger with the extra junk burried inside. this is garbage code and dumbass programming. DO NOT USE APPEND. insted rewrite the whole songfile - 128, then add the new tag, thus overwriting the old id3tag with the new.

if you have a hex editor such as ultra edit, use it to open a few of your mp3s. go to the very end. you'll see the info for the id3 tag. remember, id3 tag readers only check the last 128 bytes, so old tags can be hidden behind the one being read. you'll probably see alot where there are multiple tags at the end of the file, but only the last one is used.

By looking at the code I posted, There is nothing added right? because it seeks to the last 128 bytes before adding any information, thus, overwriting any previous tag.

actually yours does look right, overwriting the old tag.
