看个问题:

[booming]

OnInitDialog()
{
HTREEITEM hitem = m_tree.InsertItem("111");
m_tree.ModifyStyle(0, TVS_CHECKBOXES);
m_tree.SetCheck(hitem ,1);
}

没效果.

各位可以试试

你想要什么效果？

这样做是可以的。
只要你通过classwizard加的m_tree

[会的越多不会的也就越多]

Once a tree-view control is created with this style, the style cannot be removed. Instead, you must destroy the control and create a new one in its place. Destroying the tree-view control does not destroy the check box state image list. You must destroy it explicitly. Get the handle to the state image list by sending the tree-view control a TVM_GETIMAGELIST message. Then destroy the image list with ImageList_Destroy.


If you want to use this style, you must set the TVS_CHECKBOXES style with SetWindowLong after you create the treeview control, and before you populate the tree. Otherwise, the checkboxes might appear unchecked, depending on timing issues.

我英文不时太好，我的理解是创建时必须带这个类型。

SetWindowLong 或者使用这个方法。

这个控件我没太用过，CListCtrl如果要带CheckBox的话，是需要修改扩展样式才可以有CheckBox的，我想这个也同理吧。
