This macro scrolls the tree-view control vertically to ensure that the specified item is visible. If possible, the specified item becomes the first visible item at the top of the control's window. You can use this macro or the TreeView_Selectmacro, or you can send the TVM_SELECTITEMmessage explicitly.

Syntax 

BOOL TreeView_SelectSetFirstVisible( 

hwnd, 

hitem 
);

Parameters

hwnd

Handle to the tree view control.

hitem

Handle to an item. If the hitemparameter is NULL, the control is set to have no selected item.

Return Value

TRUE indicates success. FALSE indicates failure.

Remarks

Tree view controls display as many items as will fit in the window. If the specified item is near the bottom of the control's hierarchy of items, it might not become the first visible item, depending on how many items fit in the window.

If the specified item is the child of a collapsed parent item, the parent's list of child items is expanded to reveal the specified item. In this case, the parent window receives the TVN_ITEMEXPANDINGand TVN_ITEMEXPANDEDmessages.

Using the TreeView_SelectSetFirstVisiblemacro is equivalent to sending the TVM_SELECTITEM message with its flagparameter set to the TVGN_FIRSTVISIBLE value.

Requirements

Windows Embedded CE Windows CE 1.0 and later
