This is really a C++ question, not Outlook.
Try to post in a VS newsgroup.

Yes,
I think this is my problem:
"This code won't even compile, as it will see the MyHost declaration,
thinking it is a constructor, and then realizing it is in a MatarotHost
class declaration, will yield an error.

The GetIPictureDispFromPicture is a protected method, so it is only
exposed internally to classes that derive from AxHost."

How could I Show icon on a commandBarButton?
without this method?
Using vs.net 2003 & outlook 2003
What is derived classs?

Hi,
I funded the problem:
Add-in runing only on computer having a VS.NET
If the Visual Studio is not installed I don't get my com add-in because
of
public class MatarotHost : AxHost
Why?
Or if I don't add this class, It's running good.
Thank's,
Yael.

public class MatarotHost : AxHost
{
public MatarotHost() : base( "02FD5840-C1A3-448E-8310-98611DF58281"){ }
public static stdole.IPictureDisp IPictureDisp(System.Drawing.Image
Image)
{
return
((stdole.IPictureDisp)(AxHost.GetIPictureDispFromP icture(Image)));
}
