@ schlafenhamster: what do you use this function? Parameter is what mean? Trouble to explain the wow, thank you

From the root node traversal do contrast

For example,

 
Void CLeftView: : OnSelchanged (NMHDR * pNMHDR, LRESULT * pResult) 
{
PNMHDR NM_TREEVIEW * pNMTreeView=(NM_TREEVIEW *); 
//TODO: Add your the control notification handler code here 
CMainFrame * pMain=(CMainFrame *) AfxGetMainWnd (); 
//get LeftTree 
CTreeCtrl& LeftTree=this - & gt; GetTreeCtrl (); 

TVITEM * pNew=NULL; 
//
Char tvinamenew [MAX_PATH]; 
PNew=& amp; (pNMTreeView - & gt; ItemNew); 
This - & gt; GetTreePath (pNew tvinamenew); 

Char DirName [MAX_PATH]; 
Char DriveName [MAX_PATH]=""; 

Strcpy (DirName, tvinamenew); 
//
If (stricmp (DirName, "MY COMPUTER")==0)//yes 
{
PMain - & gt; ListMyComputer (); 
PMain - & gt; ComboMyComputer (" My Computer "); 
* pResult=0; 
return; 
} 
If (stricmp (DirName, "Control 802 d")==0)//yes 
{
PMain - & gt; List802D (); 
PMain - & gt; Combo802D (" Control 802 d "); 
* pResult=0; 
return; 
} 
//not "MY COMPUTER" and "CONTROL 802 d 
"BOOL MyPC; 
MyPC=pMain - & gt; CutDriveName (DirName); 
//
If (MyPC) 
{//contain "My Computer" 
PMain - & gt; ListFiles (DirName, TRUE); 
PMain - & gt; ComboMyComputer (DirName); 
} 
The else 
{//contain "Control 802 d 
"PMain - & gt; List802Files (DirName, TRUE); 
PMain - & gt; Combo802D (DirName); 
}

Has been found that as long as know the treeitem full path
This - & gt; GetTreePath (pNew tvinamenew);
