Problem - Value not excepted

Daniel Strigl

Hi guys! I have a problem with my ActiveX component, that i developed (with VS.NET, ATL7, C++)! I created a ActiveX component with one property "FileName", who's a BSTR. I have included my ActiveX component in a Visual Basic sample. The property "FileName" is visible in the object property viewer and I can change his value! That's fine! But when I start my Visual Basic sample, the ActiveX component will use the old standard value of "FileName" and not the value I have changed during the design time! Is this normal? How can I fix it? Here is a little of my source code, the header file:

// FileLogTarget.h : Deklaration von CFileLogTarget
#pragma once
#include "resource.h" // Hauptsymbole
#include
#include "DCIpuControl2003.h"

// CFileLogTarget
class ATL_NO_VTABLE CFileLogTarget :
public CComObjectRootEx,
public IDispatchImpl,
public IPersistStreamInitImpl,
public IOleControlImpl,
public IOleObjectImpl,
public IOleInPlaceActiveObjectImpl,
public IViewObjectExImpl,
public IOleInPlaceObjectWindowlessImpl,
public CComCoClass,
public CComControl
{
public:

CFileLogTarget() : m\_bstrFileName(OLESTR("IpuLogFile.dat"))
{
	m\_bAutoSize = TRUE;
    m\_bResizeNatural = TRUE;
    SIZEL sPix, sHiM;
    sPix.cx = 32;
    sPix.cy = 32;
    AtlPixelToHiMetric(&sPix, &sHiM);
    m\_sizeExtent = sHiM;
    m\_sizeNatural = sHiM;
}
