EnsureVisible and GetVisibleCount Methods of TreeView Control in Visual Basic 6

If at some point during the execution of your program, you need to make sure that a node in the TreeView is visible, you can use the EnsureVisible method of a specific node:


This makes the node with an index of 23 visible to the user even if the node is several levels deep in a tree that is completely collapsed. The EnsureVisible property expands the tree to make the node visible.

To get the number of nodes visible at any one time, you can use the GetVisibleCount method of the TreeView control. By using


you will get a count of nodes visible within the TreeView. The count will only include those nodes that are visible, including any nodes partially visible at the bottom of the control. The count does not include any nodes expanded below the bottom edge of the TreeView control.
