    Edit box closing problem

    Hi all,
    I am doing a win32 application,In that iam creating a dialog box and inside the dialog box one list control also,using resource editor.
    For Editing the items and subitem of list control i created a edit box also(When user double click on control).My problem is, after enter the text on edit box if user pressing Enter key,the dialog box itself closing(Actually i need to delete the edit box only).How to do that.Relevent parts of code given below.Please help me
    Code:
    //Dialog procedure
    HWND hEdit=NULL;
    LRESULT CALLBACK DlgtProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
    {
     switch (uMsg)
    {
    case WM_INITDIALOG://setting the items & subitem values
    break;
    case WM_NOTIFY:
      switch(LOWORD(wParam))
     {
         case IDC_LISTVIEW:
          switch(((LPNMHDR)lParam)->code)
         {
               case NM_DBLCLK:
                if(hEdit!=NULL)
    	SendMessage(hEdit,WM_KILLFOCUS,0,0);
               RECT SubItemRect;
    				if(ListView_GetSubItemRect(hwnd,ItemClicked.iItem,ItemClicked.iSubItem,LVIR_BOUNDS,&SubItemRect))
    				{	int iHieght=SubItemRect.bottom-SubItemRect.top;
    					int iWidth=SubItemRect.right-SubItemRect.left;
    			
    					iWidth=iWidth/3;
    
                                                                         //creating edit box when user double click					                                        hEdit= CreateWindowEx(WS_EX_CLIENTEDGE, _T("EDIT"), _T(""), WS_CHILD | WS_VISIBLE|ES_WANTRETURN |ES_UPPERCASE , 
    						SubItemRect.left, SubItemRect.top,iWidth,1.5* iHieght,hwnd,0, GetModuleHandle(NULL), NULL);
    					SetFocus(hEdit);
    					wphEditProc=(WNDPROC)SetWindowLong(hEdit,GWL_WNDPROC,(LONG)hEditProc);
               break;
           }
         break;
     }
    break;
    
    }		
    }
    Edit box procedure:
    LRESULT CALLBACK hEditProc (HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
    {
    
    	 switch (uMsg)
    	 {
    
    	 case WM_KILLFOCUS:
    		 {
    			 LV_DISPINFO lvDispInfo;
    			 ZeroMemory(&lvDispInfo,sizeof(lvDispInfo));
    			 lvDispInfo.hdr.hwndFrom=hwnd;
    			 lvDispInfo.hdr.idFrom=GetDlgCtrlID(hwnd);
    			 lvDispInfo.hdr.code=LVN_ENDLABELEDIT;
    			 lvDispInfo.item.mask=LVIF_TEXT;
    			 lvDispInfo.item.iItem=iItem;
    			 lvDispInfo.item.iSubItem=iSubItem;
    			 lvDispInfo.item.pszText=NULL;
    			 char szedtTxt[100];
    			 GetWindowText(hwnd,(LPWSTR)szedtTxt,100);
    			 lvDispInfo.item.pszText=(LPWSTR)szedtTxt;
    			 lvDispInfo.item.cchTextMax=lstrlen((LPWSTR)szedtTxt);
    			 SendMessage(GetParent(GetDlgItem(hwnd,IDC_LIST1)),WM_NOTIFY,(WPARAM)IDC_LIST1,(WPARAM)&lvDispInfo);
    			 DestroyWindow(hwnd);
    			 break;
    		 }
                               break;
                                case WM_KEYDOWN:        Handler for keybord events
                                   switch(wParam)
                                     {
                                          case VK_RETURN://Control is not going here.
                                              break;
                                     }
                              break;
    	     }
    	return CallWindowProc(wphEditProc, hwnd, uMsg, wParam, lParam);
             }

    Re: Edit box closing problem

    This is a good explanation, what happens when Esc key is pressed in Win32 modal dialog:
    http://www.williamwilling.com/blog/?p=28
    When Esc is pressed, WM_COMMAND with wParam = IDCANCEL is sent.
    When Enter key is pressed, WM_COMMAND with wParam = IDOK is sent (see also http://support.microsoft.com/kb/102589). Try to ignore these commands, at least when edit box is active,
