XTP 12.0.1. This error only occurs for some OCX controls (mainly our own).

I have a dialog with an OCX control.

BOOL CMyDialog::OnInitDialog()

{

SetFlag(xtResizeNoSizeIcon);

CXTResizeDialog::OnInitDialog();

SetResize(...);

SetResize(IDC_OCX_CONTROL, ...);

// This solves the problem:

// CRect rect;

// GetClientRect(rect);

// int cx = rect.Width();

// int cy = rect.Height();

// SendMessage(WM_SIZE, SIZE_RESTORED, MAKELPARAM(cx, cy));

return TRUE;

}

The OCX will not be sized properly until a WM_SIZE message is sent! What could be the cause?
