  Ok, and when I try using TCITEM structure, problem of disappearing controls is not solved:

  ---

  void CMFC02Dlg::OnTcnSelchangeTab1(NMHDR *pNMHDR, LRESULT *pResult)

  {

  CString tmpString;

  *pResult = 0;

  int selectedTab = Tab.GetCurSel();

  TCITEM newItem;

  if (selectedTab == numberOfTabs)

  {

  tmpString.Format("Scenario %d", numberOfTabs+1);

  newItem.mask = LVIF_TEXT;

  newItem.dwState = TCIF_STATE;

  newItem.pszText = (LPSTR)&tmpString;

  newItem.iImage = -1;

  Tab.SetItem(numberOfTabs, &newItem);

  Tab.InsertItem(numberOfTabs+1, "(new scenario)");

  numberOfTabs++;

  }

  }

  Ok, I fixed the defect - I just inserted this->RedrawWindow() and came back to deleting/inserting items which is MUCH easier for me, and all is fine now.

   

  Thanx anyway!

  Yes you need to use TCITEM struct. And this is faster and better than your code.

  Well I tried Tab.SetItem(number, "Title") with "number" containing a number of last item, but it didn't work, it just says:

  cannot convert parameter 2 from 'CString *__w64 ' to 'TCITEMA *'

  In msdn, under "CTabCtrl" there is no "events" link and also I searched keyword "OnTcnSelchange" with no result so I thought it is not documented.

  Thanx for the help with msdn!

  You can obmit the delete. This adds the new entry in front of the last one:

  if (selectedTab == numberOfTabs)

  {

  tmpString.Format("Scenario %d", numberOfTabs+1);

  Tab.InsertItem(numberOfTabs, tmpString); // (adding)

  numberOfTabs++;

  }

  This notification is well documented:

  I directly see no problem.But why do you delete the last item. Just use SetItem and change the text of the last item and add a new one.

  Should I use TCITEM structure instead of string If so, I guess it is more complicated way, isn't it
