Hi Bertrand, this discussion should help you in this task.

Roberto's link discusses how to retrieve all the checked items in a tree. Before CVI 2009, only tree cells in the first column could contain a checkbox. You can set/get the value of that check box with S(G)etTreeItemAttribute(panel, tree, item, ATTR_MARK_STATE) or S(G)etTreeCellAttribute(panel, tree, item, 0, ATTR_MARK_STATE).

Since CVI 2009, any tree cell can contain a checkbox. You can set/get the value of a checkbox in any tree cell with S(G)etTreeCellAttribute(panel, tree, item, col, ATTR_MARK_STATE)

Thank you very munch for your help.

It was not ovbious to me that  S(G)etTreeCellAttribute(panel, tree, item, col, ATTR_MARK_STATE) has also to be used for checkboxes in other columns
