Dodataexchange (cdataexchange * PDX) favorites
There is such a function in the dialog box.
It is used to exchange data with the corresponding variable dialog box.
Msdn explains:
Called by the Framework to exchange and validate dialog data.
Virtual void dodataexchange (Cdataexchange * PDX);
PDXA pointer to a cdataexchange object.
The data exchange in the dialog box refers to the following two operation
change, of course, the new control that uses wm_notify messages can process the onnotify function in the same way. the following is a simple example of using this technology. When you enter data in the dialog box, the data in the main window is changed accordingly.

version of oninitdialog () after the handle to our window exists. we modify the create function of cdialogbar to do this. since create () for a cdialogbar is overloaded we redefine each create and make out modifications to it.
First in the cinitdialogbar class redefine the public create functions:
BOOL Create(CWnd * pParentWnd, UINT nIDTemplate, UINT nStyle, UINT nID);BOOL Create(CWnd * pParentWnd, LPCTSTR lpszTemplateName, UINT nStyle, UINT nID);
By doing this, we don't change the way our cini
Network designers use firewalls to protect networks from unauthorized use. Consider a lock on a door to a class inside a building. The lock allows only authorized users with a key or access card to pass through the door. Similarly, a firewall filters unauthorized or potentially dangerous packets from entering the network. On a Cisco router, you can configure a simple firewall that provides basic traffic filtering capabilities using ACLs. Administrator
