Given the following tree layout, the tree structure fails to draw correctly in the report.

1
x2
xx3
xxx4
xxx5
x6

The DrawTreeStructure routine is broken and would not draw the line between 2 and 6 in the rows containing 4 and 5.

Here is the fix, to just the while loop.

pRow = pRow->GetParentRow();

if (pRow == NULL || pRow->GetParentRow() == 0 || pRow->IsGroupRow())
{
break;
}

rcItem.OffsetRect(-nTreeIndent, 0);
if (!pRow->IsLastTreeRow())
{
pDC->FillSolidRect(rcItem.left, rcItem.top - 1, 1, rcItem.Height() + 1, clrTreeStructure);
}

The "IsLastTreeRow" was causing it to abort early. In my simple (and maybe wrong) fix, I only used it to test to see if we draw the line.
