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.

NiceNaiduHow can I test for ONLY TVIS_EXPANDED?

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.

You still seems confused, since your question doesn't make sense.

SQL is, to my knowledge, a language for dealing with database queries.
A SQL database is a database that supports the SQL language.
A database usually resides in some kind of (remote) server machine.

In order to communicate with a database (SQL or not), your program has to "talk" to the server that hosts the database. And of course, the database itself.

Two ways to communicate with a database is ODBC and ADO. There are other ways as well.
