/////////////////////////////////////////////////////////////////////////////
// CSample4Dialog
//
// As described in the overview of the programmers guide,
// you can use a grid as dialog control in a dialog template.
//
// CSample4Dialog is based on the IDD_DLGSAMP4 dialog template.
// I have dragged an user control into the dialog template and
// set the control class to "CSample4GridWnd".
//
// CSample4GridWnd is registered in CGridSampleApp::InitInstance
// which calls the method CSample4GridWnd::RegisterClass().
//
// The macro GetGridWnd() returns a pointer to the grid window.
// OnInitDialog calls the Initialize method of the grid.
//
// In DoDataExchange, I have added the line
// DDV_GXGridWnd(pDX, GetGridWnd());
// which enables control validation in the dialog.
