* http://stackoverflow.com/questions/31488233/treeview-setextendedstyle-does-not-apply-certain-styles-what-am-i-doing-wrong
|

* the TreeView control should have the extended check-box style set
|
||||
* *BEFORE* actually setting the check-box window style, because it is
|
||||
* only at that step that the TreeView control builds its image list
|

* containing the three check-box states. Indeed, if the extended
|
||||
* check-box style was applied after setting the window style, then
|
||||
* the image list would be already built with the default two states
|
||||
* and would not be updated.
|

*
|

* The MSDN documentation is not very clear on that point.
|

*
|

* Let me also take this opportunity to document what those
|
||||
* extended check-box state styles look like on Windows Vista+ :
|
||||
*
|
||||
* - TVS_EX_DIMMEDCHECKBOXES creates a grey tone version of the normal checked box state.
|
||||
* - TVS_EX_EXCLUSIONCHECKBOXES creates a red 'X'-style cross check-box state.
|
||||
* - TVS_EX_PARTIALCHECKBOXES creates a filled box.
