Application Security Testing: An Integral Part of DevOps



To retrieve the index of the first selected item use GetNextItem(). As its name implies, you can use also use the GetNextItem() function to retrieve the index of the next selected item. The code below prints out the indices of all selected items to the debug window.
// This code prints out the indices of selected items to debug win
 int i = GetNextItem( -1, LVNI_ALL | LVNI_SELECTED);
 while( i != -1 )
 {
	TRACE("%d\n", i );
	i = GetNextItem( i, LVNI_ALL | LVNI_SELECTED);
 }

    if (pString)

    UpdateData(FALSE);

    *pResult = 0;

  • Example did not work; but MSDN solution did

    Although, in theory it should have worked.

    The solution from MSDN is:

    CListCtrl* pListCtrl = (CListCtrl*) GetDlgItem(IDC_YOURLISTCONTROL);
    ASSERT(pListCtrl != NULL);

    POSITION pos = pList->GetFirstSelectedItemPosition();
    if (pos == NULL)
    TRACE0("No items were selected!\n");
    else
    {
    while (pos)
    {
    int nItem = pList->GetNextSelectedItem(pos);
    TRACE1("Item %d was selected!\n", nItem);
    // you could do your own processing on nItem here
    }
    }

    This did work.

  • Global data deduplication provides important benefits over traditional deduplication processes because it removes redundant data through entire enterprises, not just single devices. Global deduplication increases the data deduplication ratio — the size of the original data measured against the size of the data store after redundancies are removed. This helps reduce the amount of storage required at a time when businesses face exponential storage growth. This eBook explores the chief benefits of global …

  • IT planners have far more options as to where to run their workloads than ever before. On-premises data centers, co-location facilities and managed services providers are now joined by hybrid multi-clouds – a combination of Software-, Infrastructure- and Platform-as-a-Service (SaaS, IaaS, and PaaS) execution venues. All have unique operational, performance and economic characteristics that need to be considered when deploying workloads. Submit the form to watch this webinar replay featuring 451 …
