ListControl in a Dialog box

[mpsoutine]

Hi,

I'm trying to populate a list control within a dialogbox with the records in a database. The user clicks on a "Show Employee List" button and a dialogbox appears. I'm trying to populate the the list control within DoModal().

The following runtime error was generated when I ran the program and debugged: I've figured out that I'm trying to get information about a window that does not exist yet. This makes sense but I can't figure out where I should put the code to get information about the List Control.

_AFXWIN_INLINE void CWnd::GetClientRect(LPRECT lpRect) const
{ ASSERT:IsWindow(m_hWnd)); ::GetClientRect(m_hWnd, lpRect); }


Here is my Do Modal function.

int CCheckListDialog:oModal()
{



/**************************************************************************
Beginning of code to populate the List Control
***************************************************************************/
CRect clientRect;
int colWidth;


m_lcEmployeeList.GetClientRect(&clientRect);

colWidth = clientRect.Width()/3;

CString FirstName = "First Name";
CString LastName = "Last Name";
CString Birthday = "Birthday";

m_lcEmployeeList.InsertColumn(0,FirstName,LVCFMT_CENTER,colWidth,-1);
m_lcEmployeeList.InsertColumn(1,LastName,LVCFMT_CENTER,colWidth,-1);
m_lcEmployeeList.InsertColumn(2,Birthday,LVCFMT_CENTER,colWidth,-1);


CPersonSet Tmpset;
CPersonSet* m_pSet = &Tmpset;

CListCtrl* pList;
pList = &m_lcEmployeeList;

Tmpset.PopulateItems(pList);

/**************************************************************************
End of code to populate List Control
***************************************************************************/

return CDialog:oModal();


}

Over ride OnInitDialog and put this initialization code in there.

Hi, mpsoutine

I have the same problem that you had.
Would it be possible if you could post your PopulateItems function?
