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

This notification is well documented:
http://msdn.microsoft.com/library/en-us/shellcc/platform/commctls/tab/notifications/tcn_selchange.asp frame=true

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.

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++;

}

}

It sure makes the code neater!

But now I got a new problem. If you can help, please try:

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++;

}

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!

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!

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