Ok dudes my way is maybe not the fastes to use in runtime, but it works for me in any case i have tested so far. In the beginnin of my proggys i put in a function to get the size and store it in a global variable (yeah i have heard this would be bad, but i dont care about this)

here the explanation:

1. Create a treeview (invisible if u want)
2. Create an imagelist with atleast 1 image inside (size 16x16)
3. Set the imagelist to the treeview ("TVSIL_NORMAL")
4. Get the "TVSIL_STATE" imagelist from the treeview (u have to create "TVSIL_NORMAL" before, otherwise this one will fail!)
5. Use ImageList_GetIconSize(..) and store the size. Wow, the checkboxs and the radio-buttons have the same size as the state icons of the treeview. Now u have what u want!
6. Destroy the "TVSIL_NORMAL" imagelist
7. Destroy the treeview

this code needs only a few microseconds at the beginning of my proggies and i can use the value everytime i need it.
