Inspired by @steve's script (link), I am wanting to create a reduced version to modify the metadata of a single file. But the only thing I have managed to do is create the graphic part as I show below:
Could someone give me an example of how a resource is related to a function? Mainly how can I select the file, thank you very much.
Mp3 Tag File.js.txt (5.6 KB)
Does anyone know of an article where I can learn about ListView, ComboBox and Edit Control; And how to assign functions to buttons?
How could I convert that ListView into Edit Control:
<control fullrow="yes" height="15" multisel="yes" name="listFiles" type="listview" viewmode="list" width="147" x="63" y="5">
<columns>
<item text="Filename" />
</columns>
</control>
And that ComboBox into Edit Control:
<control edit="yes" height="40" name="cmbTitle" type="combo" width="147" x="63" y="23">
<contents>
<item text="<keep>" />
</contents>
</control>
I have tried several different things but I can't. Thank you!
The only place I know of is the manual.
Here is an example of a basic dialog. But it is in vbscript unfortunately.
Also you should read the part of Dialog, Controls and Messages, among others parts in Scripting Objects as well.
To change a control type, it is not enough to modify a name or a line, you must first understand what properties and methods it has. E.g. A listview is filled very different from an Edit Control.
I suggest you if you are starting, to make the changes of the resources from the Script Editor, not from the same script.
After that you can modify the code that handles the control. Is not enough with just "taking out" the control from the dialog, as there are probably parts of the code that references it.
Likewise, I have spent all day searching in the manual and on Google, and little clear information appears, at least for me who has no training in programming.
That is what I have done, I have changed the "types", but it is not enough, each one has a structure, a syntax, and each one several dependencies, but I don't know how to do that, those things are not learned in a day Thank you very much @errante!
@errant, let me ask you a question, in the Script Editor it appears:
And this last one (Control de Edición), or name in English would be which one? The name that should appear in type="Control de Edición". Thank you.
Control de Edición = Edit Control
Perfect! That text box is the simple text box, right?
Static Control = Hold text that is not editable by the user
Edit Control = User can edit their content
Excellent, I will continue trying, one day I will succeed 
Could someone help me correct this error, which is not letting me show the dialog? The error is on line 35, dlg.Create(), a method was called unexpectedly. Thank you.

Mp3 Tag File.js.txt (7.0 KB)
You need to initialise the dialog before you can create it, e.g. you have a template dialog called "Mp3TagFile" but nowhere do you tell the dialog object that's the dialog you want to create.
@Jon Excuse my ignorance, but I don't understand much of these things. I inserted the line dlg.template = "Mp3TagFile"; in front of dlg.Create() and that error is no longer shown, but now another one is shown on the line archivo.value = item.name_stem; item is not defined.
I tried to define var item = with multiple values but no success. I specified that whole part of the code (.value = ) as a comment (/* */) and it doesn't generate any errors, and the dialog tries to appear, but disappears. 
I have removed most of the code just to try to display the dialog but I still can't do it, can someone please help me?

@lxp you have saved my life again, thank you a thousand times, I spent the night without sleep studying about the dialogue object, and although I have learned some things, I would never have reached that result, gratitude, gratitude
Happy tagging! 
Now I incorporated this part into the code and it generates an error, it tells me that dlg is not defined, I thought it was: var dlg = scriptCmdData.func.Dlg();
var archivo = dlg.Control("archivo");
var titulo = dlg.Control("titulo");
var artista = dlg.Control("artista");
var album = dlg.Control("album");
var anio = dlg.Control("anio");
var pista = dlg.Control("pista");
var genero = dlg.Control("genero");
var comentario = dlg.Control("comentario");
var artista_album = dlg.Control("artista_album");
var compositor = dlg.Control("compositor");
var numero_disco = dlg.Control("numero_disco");
var caratula = dlg.Control("caratula");You probably need to use quotes and append .value.
var archivo = dlg.Control('archivo').value;
