Invalid FORMATETC structure (Exception from HRESULT: 0x80040064(DV_E_FORMATETC))

After I successfully created a .dll library for a user control, my next step was to be able to add it to the Toolbox. When I select 'Choose items' on the toolbox tab and add the .dll, I received a message 'No components found to be able to add to Toolbox'.

I got around this problem by adding an ToolboxItem(true) attribute to the user control's code behind class.

However, once the control was on the Toolbox, it gave me a 'Invalid FORMATETC structure (Exception from HRESULT: 0x80040064(DV_E_FORMATETC))' error message when I tried to drag and drop that control to the design surface.

Please advise. (I am using VS2005 and .NET 2.0, Visual C#).

This means designer has failed to instantiate the control. Try setting breakpoint in control constructor and other methods that may be called by the designer and check if they throw exceptions. You may have to run two copies of VS in order to do it - one as debugger and another as application that uses the control.

Thanks

Hello Mikhail,

I don't have any constructor implementation in my User Control's code behind, neither do I have any methods for the designer.

All I have is a ToolboxItem(true) and ToolboxData() attributes defined for the code behind partial class of the user control.

Thanks.
