CommonControls (Replacement of the MS common controls)

[LaVolpe]

@ LaVolpe,
Thanks for your input and suggestion. I know of those messages you mention. But what to do when comctl v5.8x is used and not v6.0?

Force ppl to manifest their projects

I know what you mean.

Edited: Actually, if the lParam of the LVITEM structure is not exposed to the user, then this can be used same as mapping for Listview items. Simply keep an incrementing value that is assigned to lParam member when user-defined properties are set. To locate the item by the value you placed in the lParam member, send LVM_FINDITEM with its .flags set to search the lParam. I wouldn't be surprised if this isn't very similar to how the LVM_MAPxxx messages work. Not familiar enough with treeviews to suggest a similar method as its mapping messages.
