  Hi,
  I need some help. I have an application with a ListView in the main window. From the menu I can open a dialog to add items to the listview. But it doesn't work. I get this error when I try to add a item:
  
  Debug Assertion Failed!
  
  Program: ...
  File: f:\rtm\vctools\vc7libs\ship\atlmfc\include\afx.cmn.inl
  Line: 148
  
  When I click on the OK button in the dialog, it takes the text from a edit control, put it in 'CString ItemTxt' and calls the function below:
  
  void CApplicationView::AddItem(CString ItemTxt)
  {
     // Converts CString to char
                 const size_t newsize = 100;
                 char n_ItemString[newsize];
     strcpy_s(n_ItemString, ItemTxt);
  
     CListCtrl& ListCtrl = GetListCtrl();
  
     LV_ITEM lvi;
     
     lvi.mask = LVIF_TEXT;
     lvi.iItem = 0;
     lvi.iSubItem = 0;
     lvi.pszText = n_ItemString;
  
     ListCtrl.InsertItem(&lvi);
  }
  
  Does anyone have any idea whats wrong? Please help me!
