Can a dynamic button label show a drive name/label?

Can a dynamic button label show a drive name/label?

I have the following button:

@hideif:=!Exists("K:\")
@icon:"K:\driveicon.ico"
Go K:\

Is there a way with @label or evaluator code make the button label display the K: drive name or label?

2

@label:Root(source)

3

That would show the current drive letter, not the K drive’s label.

Replace all three lines with something like this:

Go DRIVEBUTTONS=+K,iconlettersoff,lettersbeforelabels

You might want slightly different arguments at the end, depending on how you want the label to look.

What I was hoping to do was make a button that would work as the main button in a button menu. Then the drop-down menu could contain other commands related to the drive. The Go DRIVEBUTTONS command doesn't work in a button menu (which makes sense because it can show more than one drive).

If I can't get the removable drive's label, I can just use a generic label.

Thanks for the replies.

You can use a script to save the label to a variable and then use the variable in the button.

@hideif:=!Exists("K:\")
@icon:"K:\driveicon.ico"
@label:=$glob:LabelDriveK
Go K:\

function OnInit(initData) {
    initData.name = 'GetDriveLabel';
    initData.version = '2025-04-14';
    initData.url = 'https://resource.dopus.com/t/can-a-dynamic-button-label-show-a-drive-name-label/55393';
    initData.desc = 'Get the drive label for a drive letter';
    initData.default_enable = true;
    initData.min_version = '12.0';
}

var fso = new ActiveXObject('Scripting.FileSystemObject');
var cmd = DOpus.Create().Command();

function OnActivateLister(activateListerData) {
    var srcPath = 'K:';
    // var srcPath = 'Z:';
    var srcLabel = fso.DriveExists(srcPath) ? fso.GetDrive(srcPath).VolumeName : '<none>';

    DOpus.vars.Set('LabelDriveK', srcLabel);  // reference as $glob:LabelDriveK
    cmd.UpdateToggle();
    // DOpus.Output('Label Drive ' + srcPath + ' is ' + srcLabel);
}

Thanks, @lxp, that's great!

Appreciate the help.

The DisplayName evaluator function may do what you want.

Unless I'm doing something wrong, something like @label:=return DisplayName("K:") or @label:=return DisplayName("K:\") only gives me "K:\" for a button label and not "SanDisk 4 GB" or whatever.

try
@label: DisplayName(source, "f")

Flag or no flag - DisplayName() never returns the drive label. Maybe in the future?
