TreeView_GetCount macro

Retrieves a count of the items in a tree-view control. You can use this macro or send the TVM_GETCOUNT message explicitly.

Syntax


UINT TreeView_GetCount(
  HWND hwndTV
);

Parameters

hwndTV

Type: HWND

Handle to the tree-view control.

Return value

Returns the count of items.

Remarks

The node count returned by TreeView_GetCount is limited to integer values. If you add a node beyond 32767 the macro returns a negative value. After adding 65536 nodes the count returns to zero. When this occurs, the tree-view control appears empty with no scrollbars. For more information see the Knowledge Base article Q182231.
