Re: bitmaps in menus

When I define a menuitem from a resource, I use this code:

I_IMAGENONE, 120, TBSTATE_ENABLED, TBSTYLE_AUTOSIZE, 203, 0, 0,

The string is defined by 203 value, from a stringtable.

How to use a bitmap instead of a string ? Thanks

I use the following function. This version works for all Windows CE
platforms; I have another version for "big" Windows. I edited out some
of my specialized tools, but didn't bother to eliminate all. I can't
provide more detail or explanation (too much and/or proprietary). So
you will need to work a bit to extract what is useful for you.
