Create Combobox with ToolTips

[symreds]

The code we can download does not compile because m_lstCombo.CreateEx() has 7 parameters instead of 5. For this reason I changed the code in this way

m_lstCombo.CreateEx( 0, dwStyle, rc, this, 0 );

then in my program I declared the object in this way:

CTooltipComboBox *pCombo = (CTooltipComboBox*)GetDlgItem(IDC_... ); // IDC_... resource ID of my combo

when I do

pCombo->SetItemTip(iCount, strTips);

my application crashes. Call stack: m_lstCombo is not inizialized.

I searched where m_lstCombo should be created (CTooltipComboBox::PreSubclassWindow()) => put a breakpoint inside it => PreSubclassWindow() is never called.

I tryed to create a public method (CTooltipComboBox::MyPreSubclassWindow()) with the same code of PreSubclassWindow() and I called it after pCombo definition => application crashes in

m_lstCombo.CreateEx( 0, dwStyle, rc, this, 0 );

in particular it crashes here:

BOOL CListCtrl::Create(DWORD dwStyle, const RECT& rect, CWnd* pParentWnd,
	UINT nID)
{
	// initialize common controls
	VERIFY(AfxDeferRegisterClass(AFX_WNDCOMMCTL_LISTVIEW_REG));

	CWnd* pWnd = this;
	return pWnd->Create(WC_LISTVIEW, NULL, dwStyle, rect, pParentWnd, nID); // here
}
