// FUNCTIONS:
// WndProc - Processes messages for the main window.
// MsgCommand - Handle the WM_COMMAND messages for the main window.
// MsgDestroy - Handles the WM_DESTROY message by calling
// PostQuitMessage().
// CmdModal - Brings up the modal dialog
// CmdModeless - Brings up the modeless dialog
// CmdExit - Handles the file exit command by calling destory
// window on the main window.

// is implemented in the message dispatch table, the return value is
// the value returned by the message handling function. Otherwise,
// the return value is the value returned by the default window procedure.

// COMMENTS:
// Call the DispMessage() function with the main window's message dispatch
// information (msdiMain) and the message specific information.
