I don't know how you convert them because I am not clear on what type the target is. So you need to check the definition of those fields and use an appropriate method of the Convert Class (System) | Microsoft Learn[^].

well..they are just the Track ID and Genre ID in an mp3 file...can i change the main code and switch them to string?...this is why i posted the full code on the start!!!

Richard MacCutchan8-Jun-23 5:27

I don't know the answer. You first need to know what actual type they are in the file: Byte, String, Int32, Int64, Bool etc. You then need to set a matching type in your code. Then when you get the user's selection, you may or may not need to convert what the user chooses into the appropriate type. But all that detail should have been decided before you put all this code together. And I am afraid there is far too much for anyone other than you, to know where to do this.

i think i can do the conversion here:

Dim strTag As New String(" ", 3)
        Dim strTitle As New String(" ", 30)
        Dim strArtist As New String(" ", 30)
        Dim strAlbum As New String(" ", 30)
        Dim strYear As New String(" ", 4)
        Dim strComment As New String(" ", 28)
        Dim bytDummy As Byte
        Dim bytTrack As Byte
        Dim bytGenre As Byte

setting the "as byte" to "new string" but i do not know about the numbers here??!!!

As I said above, You need to match your definitions with the actual types that are used in the file. So you need to find the definition of the file types you are trying to modify and check the requirements.

i think is Int32 Smile | :)

Fine, but you need to be certain.

i tried this but no luck:

If CheckBox5.Checked = True Then
                Dim txt = TextBox5.Text
                Dim tt As Integer = Convert.ToInt32(txt)
                tt = objMP3V1.Frame(MP3ID3v1.FrameTypes.Track) & vbLf
                objMP3V1.Update()
            End If
            If CheckBox6.Checked = True Then
                objMP3V1.Frame(MP3ID3v1.FrameTypes.Comment) = TextBox6.Text
                objMP3V1.Update()
            End If

            If CheckBox7.Checked = True Then
                Dim xt = ComboBox1.SelectedValue
                Dim xx As Integer = Convert.ToInt32(xt)
                xx = objMP3V1.Frame(MP3ID3v1.FrameTypes.Genre) & vbLf
                objMP3V1.Update()

hey..i changed my library..im now using UltraID3lib.....it seems im making it but i have another question...
how do i make mass edit in a listbox?
im using this code that was working previously but is not working now:

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click




       If ListBox1.SelectedItem = "" Then
           Dim r8 As DialogResult = MessageBox.Show(Me, "No File Selected!",

Sorry, I have no idea what you mean by "this code that was working previously but is not working now:". You need to explain what happens when you run this code and why that is not correct. Alternatively, use the debugger to step through the code to try and find out what is going on.

Member Alienoiz10-Jun-23 1:34

10-Jun-23 1:34

well...i just want to apply this code

If CheckBox6.Checked = True Then
                      myMp3.ID3v2Tag.Comments = TextBox6.Text
                      myMp3.Write()
                  End If

                  If CheckBox7.Checked = True Then
                      If ComboBox1.Text = "01 - User" Then
                          myMp3.ID3v2Tag.Genre = TextBox7.Text
                          myMp3.Write()
                      Else
                          myMp3.ID3v2Tag.Genre = ComboBox1.Text
                          myMp3.Write()
                      End If
                  End If

No, because I have no idea what your problem is. You need to show the code you are using, and explain what the problem is and where it occurs.

OK...so i have a listbox with files (mp3) and im trying to edit the tags..i can do one by one but i do not know how to tag them all at once. i want to implement this code in all files of the listbox just by using a button.

Richard MacCutchan10-Jun-23 4:03

You just need a couple of loops:

ForEach file in the ListBox
    Open the file
    ForEach CheckBox in the Form
        adjust the tags as required
    Next
    Save and Close the updated file 
Next

Put the code into a subroutine and pass it the list of filenames from the ListBox.

Member Alienoiz10-Jun-23 4:34

10-Jun-23 4:34

should be something like this right?

  Dim items = ListBox1.SelectedItem()
                For Each items In ListBox1.SelectedItems

                    If CheckBox1.Checked = True Then
                        myMp3.ID3v2Tag.Title = TextBox1.Text
                        myMp3.Write()
Next
                    End If

is not working Cry | :((

Richard MacCutchan10-Jun-23 4:51

10-Jun-23 4:51

Your first two lines duplicate each other:

Dim items = ListBox1.SelectedItem() // get a list of the SelectedItem(s)
For Each items In ListBox1.SelectedItems // do the same, but duplicating the variable name

But either way they make little sense as you do not do anything with the item you pull from the ListBox.

You need something like:

' I am making an assumption that the ListBox entries are names of the files to be processed
For Each file As String In ListBox1.SelectedItems ' Extract each file name
    ' So pass this name to a subroutine that will:
    '    Open the file
    '    Process all the tags according to the CheckBox settings
    '    Save and Close the file
Next

Try not to write all your code inline, as it makes it so much more dificult to read and, more importantly, to debug.

Member Alienoiz10-Jun-23 5:15

10-Jun-23 5:15

aaarrggghh...im not able to make it work ...could you be a little more explicit please?

Richard MacCutchan10-Jun-23 5:39

10-Jun-23 5:39

In what sense more explicit?

You know, one of the most frustrating things in these forums is when people keep saying things like, "it doesn't work". We have no way of knowing what that is supposed to mean, even when we can see your code.

So I suggest you start a new question. Make sure you post the code that you are using, and explain, in proper and complete detail what is not working, and why that is so.
