Hi All

trought the nodes.

OK i found the anwser more fast.
BUT NOW I NEED TO SELECT THE ITEM ON TREEVIEW
Edward
TTreeNode *pItem = new TTreeNode(NULL);
pItem=TreeViewRA->Items->GetFirstNode();
while(pItem!=NULL)
{
if(pItem->Text.AnsiPos(EditRA->Text.UpperCase()) !=0 )
{
ShowMessage(pItem->Text);
}
pItem=pItem->GetNext();
}
delete pItem;

TTreeNode has Selected and Focused properties for what you ask.
because ...
memory address of the TTreeNode that you created and thus can never free it
property.
that line is when the loop exits, which does not happen until pItem is NULL,
so you are always freeing a NULL pointer, which does nothing.
In any case, you are not supposed to be creating new TTreeNode instances to
begin with just to navigate the existing nodes. Get rid of the 'new' and
'delete' statements altogether, ie:
TTreeNode *pItem = TreeViewRA->Items->GetFirstNode();
while( pItem )
{
if( pItem->Text.AnsiPos(EditRA->Text.UpperCase()) !=0 )
{
pItem->MakeVisible();
pItem->Selected = true;
pItem->Focused = true;
break;
}
pItem = pItem->GetNext();
}
