On paint calling order

[Kharfax]

Hi I have a picture box in my dialog, but I need to write something on top of it. The problem is that the onPaint dialog method is getting called before the control repaints itself, so I can never see the text. Someone knows what can I do to avoid this, and be able to write on top of the picture box? Thanks in advance

Use picture box onPaint method instead of dialog onPaint method. I think, it's called event, not method.

At the end of the dialog's OnPaint method post a custom message to the dialog. In that custom message handler paint your text.

void CMyDialog::OnPaint()
{
...
CDialog::OnPaint()

PostMessage(WM\_APP + 1, 0, 0);

}

LRESULT CMyDialog::OnWmAppPlusOne(WPARAM, LPARAM)
{
ClientDC dc(this);
dc.TextOut(...);
}

Now all the usual painting is done first, then you custom message gets processed to draw the text on top of all the other controls.

Add the WS_CLIPCHILDREN style to the dialog, so the dialog's window proc won't paint over its child controls.
