How to update the child dialog box

Arbo · #1 04-Apr-2005, 15:21

Hi! I am new to VC++. Right now, I have created a child dialog box using CDialog, and then what I want to do is to display a message (in form of text fileld - m_info)in the child dialog box when a button is clicked, where the displayed message is from the parent dialog box.

CPP / C++ / C Code:

void CParent::OnCreateChild() 
{
	CDialog dlg2(IDD_DIALOG2, this);
	dlg2.DoModal();
}

void CChild::OnButton() 
{
	m_info = parent.message;
	UpdateData(FALSE);
}

I could not update the textfiled in the child dialog box, do I have to set up something in order to get the message from the parent dialog box?

Thanks.

You can use function
SetDlgItemText( int nID, LPCTSTR lpszString );

nID-Identifies the control whose text is to be set.

lpszString-Points to a CString object or null-terminated string that contains the text to be copied to the control.
