I have created a Delphi for .Net Project Package amd added some custom 
components.  I'm able to add these components to the Delphi .Net IDE and 
drop them on a VCL Form.

I would like to make these components available in the Visual Studio 2005 
IDE but I'm not having any luck adding them to the VS Toolbox.  The 
following error is reported when attempting to add the Delphi.Net package...

    There are no components in '<AssemblyName>' that can be placed on the 
toolbox.

I've added the [System.ComponentModel.ToolboxItemAttribute(true)] attribute 
to the Delphi component classes, but still no luck.

Does anyone have any suggestions of what to try next?

Thanks is advance!

Troy

Are you trying to add controls or components?

Visual Studio uses Winforms controls which have a different control
hierarchy to the VCL controls. You cannot (easily) use a VCL control
in a Winforms application.

For components there are several requirements. One is to have a
parameterless public constructor.

Marc,

Thanks for the quick response!

I'm a Delphi novice, so I'm sure what the difference is between a control or 
a component, sorry.  But the components(controls?) are inherited from 
TCustomControl, I suppose these must be controls!

Anyway, I can get the controls to "work" in VS through code by setting the 
ParentWindow property through code.

Thanks again!

Troy

To put it simply controls have a visual representation, components
don't. (The VCL also has the concept of a TWinControl which can has a
windows handle and can receive the focus and keyboard events)

Yes, though there are often some issues caused by the differences in
the way windows messages and keyboard and mouse events are handled.
