A while back I'd posted the question "How does one resize a child window on a rebar?" No one knew, there was no documentation I found in my searches, and while a few helpful suggestions pointed in a few ways, ultimately, no answer was found. So maybe a month ago I stopped looking. Until this morning, when I awoke with a new idea to try. Yep, it worked too, and is actuall very simple. Here it is on PROC form:

ResizeRebarBand PROC  hRebar:DWORD, cIndex:DWORD, cPixels:DWORD
   LOCAL rbi:REBARBANDINFO

   mov rbi.cbSize, SIZEOF REBARBANDINFO
   mov rbi.fMask, RBBIM_CHILDSIZE  
   invoke SendMessage,  hRebarLeft, RB_GETBANDINFO, cIndex, ADDR rbi
   add rbi.cyMinChild, cPixels
   add rbi.cyMaxChild, cPixels
   invoke SendMessage,  hRebarLeft, RB_SETBANDINFO, cIndex, ADDR rbi
   ret
ResizeRebarBand ENDP

That's it, the rebar will refresh itself when it gets the 2nd message. Now, with this down, I can go onto resizing all the controls places on the same band The code for that is rather long and messy (99 code lines), but uses no resources beyong a few alloc-ed bytes, but needs a real tut to explain how it do what it do.
