Dont know this error !!!

I have use Devcomponent tool for design.
Last night i have copied controls and have edited some changes. And now
ANY TIME I debug my program show :

Code:

---

---------------------------
Microsoft Visual Studio
---------------------------
The control DevComponents.DotNetBar.NavigationBar has thrown an unhandled exception in the designer and has been disabled. 



Exception:

The file D:\PROGRAM\RESTAURANT\HQ2\HQ\QLBH1.0\Mainform\Trangchu.vb cannot be modified in the designer while building or debugging.



Stack trace:

  at DevComponents.DotNetBar.NavigationBarContainer.RecalcSize()

  at DevComponents.DotNetBar.NavigationBar.RecalcSize()

  at DevComponents.DotNetBar.NavigationBar.OnHandleCreated(EventArgs e)
---------------------------
OK 
---------------------------

---

Have you met that error ?

I click OK and program still fine.
But when i change the designer file then that msbox is shown.
How can i fix it ? :down:

I could be completely wrong here, but I get similar behaviour if I try making changes in the designer and then try and run the application without saving. Try either saving the program first, and/or try and go to code view instead of form view and then run the program.
