Selecting Parent Checkbox in treeview selects childs

[redndahead]

I would like to create a treeview control with checkboxes. When the parent checkbox is selected all the children get selected. I have created a script that waits for the message from the parent and then it checks the ones that are children. The problem is that a message also occurs when you click the minus sign next to the checkbox which doesn't necessarily mean they checked the box. Has anyone found a work around to get this to work?

Check checked state in your message by _TreeView_GetChecked($hWnd, $hNode) from Auto3Lib
