Okay ... to be able to understand the problem YOU must understand how the Framework you are using is working.
I suppose that your problem comes from not using this Framework in the right way.
I, myself, don't like to use 3rd party products from which I don't know how to work with. Mostly it is easier (for me) to create it by myself ...

No, none of it is abusive. Just that he is copying stuff from the internet, and his understanding of what he copies, and general programming is not too good.

No that is definitely not the way to do it. You should set the tags as and when the user edits them*, and then save the entire set when he/she presses Save. The way you are doing it the user has no way to cancel the changes.

*You should not need all those checkboxes. Just use an event handler for when the user changes any of the tag entries. As I said yesterdsay, and as clearly demonstrated in your video, you are going about this whole project the wrong way. And until you step back and take on board some of the suggestions you have been given, and start utilising proper functions and subroutines, you will never get your "mass edit" to work.

After searching UltraID3lib library I found a lot of usable links and code samples. It seems that the code that I supplied is 100% correct. I suggest taht you run the code and then tell us where it errors, you have not done so yet but rather keep on asking the same question over and over. The library also seem to be long dead (deprecated) and the original site offering the library is also down, only sample available on Github - UltraID3Lib (Only in French)
[^]

Using Google - UltraID3lib methods [^]
Code samples below -
How to read/write ID3 Tags in MP3 files using UltraID3Lib [^]
ID3 Tags on MP3 Files [^]
View/edit ID3 data for MP3 files [^]
Does anyone have the UltraID3Lib.dll [^]

So, with all these links, testing my code sample above and some learning you will resolve your issue in no time.

According to the documentation, the code I supplied is 100% correct. Did you try and log it out to your console or create some form of message to see what it does when you call the .Write function? Maybe one of your variables (textbox's) has an empty value?

Puzzling???
Clipboard image different with different version of vision basic

Clipboard.SetImage(New Bitmap(Clipboard.GetImage, newWidth, newHeight))

Visual basic 2010 express (32bit). Size of image is as per setting newWidth, newHeight (perfect)
Visual Studio 2022 (64bit). Size of image will not change with the newWidth, newHeight (about 1/3 of previous)
Is there any issue related to 32-64bit?

Appreciate very much any helps. Thank you. Lean Chew

Given that we do not have access to the image, and you have not shown any of the code you are using, it is impossible to guess.

[edit]
I just tried your code and the image was correctly resized. You need to provide more information.

Coding. Capture screen shot to clipboard and paste to RichTextbox inside PrintBuffer
Same coding using VisualBasic 2010 (32Bit) and Visual Studio 2022 (64Bit)
The image on VB 2010 is perfect and size change with the newWidth, newHeight but with VS 2022 the image is about 1/3 size of previous and will not response to change in newWidth, NewHeight.
Dim newWidth,newHeight as integer
newWeight=710: newHeight=430
Clipboard.Clear()
SendKeys.SendWait("%{PRTSC}"): Call TimeDelay(100)
If IsNothing(Clipboard.GetImage) = False Then
Clipboard.SetImage(New Bitmap(Clipboard.GetImage, newWidth, newHeight))
PrintBuffer = DataToPrint + vbCrLf
frmPrint.ShowDialog()

I have just tried that again and it works exactly correctly, the image is resized to the values you give above. You can test this for yourself by running the ClipBoard code above, and pasting into one of the paint applications to check the new size. The problem you have is most likely to do with your printing code where you are not adjusting the mapping to account for the different point density between screen and printer. I have only ever done this using the Windows GDI library, so am not sure how you manage it in VB.NET. I suggest you open a new question asking for help on that specific subject.

Thanks again Richard.
The coding works perfect using Visual Basic 2010, size of image change as defined. However when the same coding used on Visual Studio 2022, the image size will not change with setting, about 1/3 the size by comparison. Not sure if it has anything to do with 32-64Bit platform or just another one of those bugs. My opinion is that Visual Studio 2022 is no good, It is operating like a degraded VBasic. I changed from 2010 to 2022 thinking that the 64Bit enviroment will work and run better. Disappointment. Looks like I will stay with the 2010 even though it is 32Bit. Thanks again

Well, as I have said twice now (and I just checked again), your code works perfectly with Visual Studio 2022. So whatever you are doing, and however you are measuring the image, is not the same as I am. So without more information it is impossible to make a useful suggestion.

And, to be honest, Visual Studio 2022 is one of the best IDE's I have worked with, and definitely better than the Express versions going back to 2005 and before.

2010 to 2022 is a big leap. The VS 2022 designer looks at the possible screen sizes / resolutions more closely; using them as defaults during the design. (No idea what "phase" you are talking about)

My current "default design surface" is: "13.5 in. Surface Book (3000x2000)" ... for no obvious reason since my monitors are 27 and 45 in; though it doesn't impact the way I actually use what create.

Just dumping all your code and expecting someone to fix it is quite rude. We have no idea where the error occurs. So please edit the question, remove all the code that is not relevant to the problem, mark the point where the error occurs, and include the complete text of the error message.

Hi..sorry..i posted all the code cause i do not know what is happenning at all...
anyway...thanks and i can resume yes...
when i try to save the tags:

Dim bytTrack As Byte
        Dim bytGenre As Byte

the error returns it cannot convert String to Byte..but this is only happenning in new files..if i use a pretagged file all seems good.
im using this method:

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
     If ListBox1.Text = "" Then
         Dim r8 As DialogResult = MessageBox.Show(Me, "No File Selected!",
                                "Select Files", MessageBoxButtons.OK)


     Else

         Dim objMP3V1 As New MP3ID3v1(FolderBrowserDialog1.SelectedPath & "\" & ListBox1.SelectedItem)

         If CheckBox1.Checked = True Then
             objMP3V1.Frame(MP3ID3v1.FrameTypes.Title) = TextBox1.Text
             objMP3V1.Update()
         End If

         If CheckBox2.Checked = True Then
             objMP3V1.Frame(MP3ID3v1.FrameTypes.Artist) = TextBox2.Text
             objMP3V1.Update()
         End If

         If CheckBox3.Checked = True Then
             objMP3V1.Frame(MP3ID3v1.FrameTypes.Album) = TextBox3.Text
             objMP3V1.Update()
         End If

         If CheckBox4.Checked = True Then
             objMP3V1.Frame(MP3ID3v1.FrameTypes.Year) = TextBox4.Text
             objMP3V1.Update()
         End If

         If CheckBox5.Checked = True Then
             objMP3V1.Frame(MP3ID3v1.FrameTypes.Track) = TextBox5.Text
             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
             objMP3V1.Frame(MP3ID3v1.FrameTypes.Genre) = ComboBox1.SelectedValue

         Dim r9 As DialogResult = MessageBox.Show(Me, "Operation Complete!",
                       "Tagged Files!", MessageBoxButtons.OK)
     End If

You are trying to store the text strings into both those fields which are (presumably) byte types. So you need to convert the strings into their correct value types first. As someone who claims not to be a programmer, that is a lot of code that you have written.
