Dedicated Icon for USB drive ?

[bberger]

Hi,
Could you tell me if there is a way to have a distinct Icon for a USB drives (like there is a distinct one for USB keys)?

I have search in this forum, and while people mention that it is possible (Jgn on the 29th dec 06):
> ... TC shows distinct icons for diskette, hardisk, networkdrives, cd-dvd, usb and other external disks...

I haven't found out how to do it.

Thanks in advance for your support.

No, unfortunately this isn't possible. Without admin rights, there is no way to find out whether a drive is connected via USB or internally. This is only possible for USB sticks, but only when they are formatted as a super floppy, not as a harddisk (with partition table).

Did you try or are you already using SetupDiGetDeviceRegistryProperty with SPDRP_REMOVAL_POLICY? Microsoft recommends this functions to find out if a drive is a usb drive.

Well, yes, but it requires admin rights to call the functions to get the structures needed:

SetupDiCreateDeviceInfo

>>The caller of this function must be a member of the Administrators group.<<

I'm sorry. I must have overseen this limitation

Many thanks for your quick answer Christian.

Keep-up the good work and have a nice week-end (almost time...)

Hi,

There is an possibility to define your own icon file per drive.
Windows Explorer and SpeedCommander are using it.

When you create a "autorun.inf" file in the root of your removable drive and define the ICON variable.
Example:

[autorun]
ICON=AUTORUN\NAME.ICO

You can define your own icon.

This looks like this:
(Look for the Western Digital icon from my Passport I: drive)

Windows Explorer:

SpeedCommander:

It would be even more great if this applies for non removable drives also.

Hi,

I have tried the DarkRuleR solution, it works well with Windows Explorer

But it has no effect with Total Commander

Christian, is it possible to include that in a next TC version ?

Bes regards

The problem is that the button control which I'm currently using is only accepting bitmaps as the images, not icons.

Fast icon to bitmap converting can be implemented very easy, or i miss something?

Code: Select all

Var
Icon   : TIcon;
Bitmap : TBitmap;
begin
Icon   := TIcon.Create;
Bitmap := TBitmap.Create;
Icon.LoadFromFile('c:\picture.ico');
Bitmap.Width := Icon.Width;
Bitmap.Height := Icon.Height;
Bitmap.Canvas.Draw(0, 0, Icon);
Icon.Free;
{use bitmap code}
Bitmap.Free;
end;

What do you think about the solution D1P suggested?

Or maybe using a proprietary solution.
For example:

TC scans for the file tcdriveicon.bmp in the root of every drive and if the file exists use it as drive icon.

This is embarrassing. Do you think the author doesn't know how to convert an icon into a bitmap?

The best solution would be to reuse the button bar control for the drive bars.

Hi Lefteous,

Don't feel embarrased.
I'm certainly not feeling embarresed.

The way the author replies leaves space for discussion.

I personally still have questions like.
"is this suggestion still in the process of looking into?".
"or is it to much work to program?".
etc. etc.

To make a thing clear I don't think the author needs program lessens.
I made the remark as an request for more information.

Greetz,

The problem is with the new half-transparent icons. They can't be converted to a bitmap. The delphi buttons use a bitmap where the top-left pixel gives the transparency color, so there is just either transparent or color, no half-transparence. That's one of the reasons why I had to completely rewrite the button bar code to support XP themes. I'm now using icons instead of bitmaps for the icons. But that's a self-written control, not like the drive buttons...
