help: mfc treeview

hi,

how do i bind treeview's control notification to an event handler in visual studio .net? i tried to bind TVN_SELCHANGED with an event handler.. i select the class that i want to add the event handler in 'class view' by right click on the chosen class, but the pop menu doesn't have the 'add event handler' command.. thx in advance..

Not using the .Net I was able to double click on the Tree control within a dialog box and the wizard added the event handler for me.

Below is the code that was added to the CPP file.


BEGIN_MESSAGE_MAP(CAboutDlg, CDialog)
//{{AFX_MSG_MAP(CAboutDlg)
ON_NOTIFY(NM_CLICK, IDC_TREE1, OnClickTree1)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()


void CAboutDlg:: OnClickTree1(NMHDR* pNMHDR, LRESULT* pResult)
{
// TODO: Add your control notification handler code here

*pResult = 0;
}

i didn't use dialog or anything like that.. i just coded the codes for treeview in the initialupdate().. is there any otherway to add the control notification and the event handler without knowing the tree control id? thx.

IF you are creating the object from scratch, you should have an ID assigned to it.
Just substitute the ID for where IDC_TREE1 is in my example in your message map area.
Add in your handler prototype as demonstrated
Define the handler prototype in the header file.


or

Create a dummy dialog or use the default About.
Add the Tree control using the wizards.
OBserve what changes are made to the related files.
Make the similar type of changes to your target files.
