unsupported operation was attempted error

In an MFC Dialog based application,
I didnt have a linker error but I got an error at runtime as follows;

"An unsupported operation was attempted."

Then the application is closed...


Reason for the Error :

I have added the Combo box in a MFC dialog application and added the control variable for it.

wizard will add the code as follows : DDX_Control(pDX, IDC_cboDeviceList, m_cboDevice);

later for some reason, I deleted the combo box from the dialog.

But the following code is still in my dialog application

DDX_Control(pDX, IDC_cboDeviceList, m_cboDevice);

and causes the error "the unsupported operation was attempted"
