When I`m runing my prog there comes always "Gebug Library Wiindow, and the marks me always the folloing PORBLEM. What can I do?
HWND CDataExchange:repareCtrl(int nIDC)
{
ASSERT(nIDC != 0);
ASSERT(nIDC != -1); // not allowed
HWND hWndCtrl;
m_pDlgWnd->GetDlgItem(nIDC, &hWndCtrl);
if (hWndCtrl == NULL)
{
TRACE1("Error: no data exchange control with ID 0x%04X.\n", nIDC);
Debugermark-> ASSERT(FALSE);
AfxThrowNotSupportedException();
}
m_hWndLastControl = hWndCtrl;
m_bEditLastControl = FALSE; // not an edit item by default
ASSERT(hWndCtrl != NULL); // never return NULL handle
return hWndCtrl;
}

This message infers that you haven't defined any class member variables that have been allocated or defined the available DDX (DynamicDataExchange) capabilities to. If you added a class variable via the CLASS WIZARD this is automatically done. However if a variable is added manually you need to add this function call yourself.

I suggest that you look at the class wizard, add a variable to the class and either copy the syntax or look in the online help for the explanation and syntax for the dynamic data exchange functions within visual c++.

I have the same problem. I do have the necessary class member variables
declared. Did you manage to solve your problem?
