Re: CTreeCtrl GetItemState related [modified]

2-Apr-07 0:33

Hi All,
I want to examine whether a node in the tree control is presently expanded or not (i.e. it has the '-' sign infront of its label.
I cannot do it with GetItemState(hItem,TVIS_EXPANDED).
The problem is that the return value of GetItemState is the combination of the flags TVIS_EXPANDEDONCE and TVIS_EXPANDED.
How can I test for ONLY TVIS_EXPANDED?

Thanks in Advance.

Did you tried like..

if( TVIS_EXPANDED == GetItemState(hItem,TVIF_STATE)&TVIS_EXPANDED)<br />
{<br />
      // items is expanded.<br />
}

How you are verifying this?

UINT nState = GetItemState(hItem, TVIS_EXPANDED);<br />
if(nState & TVIS_EXPANDED)<br />
{<br />
 //Add the Expanded bitmap for the Tree Node<br />
}<br />
else<br />
{<br />
 //Add the Expanded bitmap for the tree Node<br />
}

the above code is working fine in all cases.
When there are some child items under a node.It is showing the Expanded bitmap.
But whenever i delete all the child nodes, i am expecting code in the else to be executed.

But it is not happening.
How is this possible ??
Thanks guys for u r response.
Naveen your code also is not working.

It all depends on what framework you're using.

Try looking here, try something, and come back if you have a specific problem

You seem to be confused. You will still needs lots of code regardless of whether you use ADO, or ODBC.
