Getting size of the list window.

[sthalasayanam]

Can I call GetClientRect() to retrieve the size of the list window ( a child control to the dialog) in the constructor of the dialog box. Example: CMyDialog::CMyDialog() { CRect rect; m_List.GetClientRect(&rect); } Normally, the function is invoked in the InitDialog() function?. I am bit confused about this. thanks for help in advance NSS

No,You can call the function only after your control is created.

Probably you are interested in doing something like this in the constructor:

CListCtrl \*pW = (CListCtrl \*)GetDlgItem(IDC\_LIST1);
CRect rc;
if ( pW ) 
{
	pW->GetClientRect(&rc);
	int z = 1; // Debug point
}

When executing the first line, you come to the following assertion: ASSERT(::IsWindow(m_hWnd)) which actually tells you that the child window is not a window yet. That is why you have to place the code in OnInitDialog() SkyWalker -- modified at 3:10 Monday 10th October, 2005
