System Tray Icon Sizes

[John Veldthuis]

What sizes can the system tray icons be?

I have a utility that I display a number as an icon. I do it by using drawstring into the icon
bitmap and displaying it. It is fine as long as the number is only 2 digits but when it hits 3 the
text runs off the end of the icon and you cant see it anymore. I get around this by making the font
smaller but it makes it hard to read then.

An ideal way would be to do something like the clock does but I am unable to work out how it does
it. Any ideas? The icon I use is a 32x32 which I cut down to 16x16. Another way I thought of doing
it was to make it 24x16 and that would give me the extra width but it does not work.

The clock is not an icon.

You may want to use an explorer bar instead:
