Hello I downloaded the source code of VNC and had a look at it.
Apparently VNC makes screen captures for a Win32 PC by using API's such as GetDIBits(). But it's not clear to me how the server part of the application knows that something has changed on the screen of the PC. Furthermore ,I don't know if VNC makes a screen capture of the entire screen or just of the part that has been changed. I saw in the source code that regions are beeing used with API's such as GetRegionData() and I gather VNC is using regions to determine which part of the screen has to be refreshed, but I'm not familiar with regions and I didn't manage to understand how it works. Can anyone help me ? Thank you in advance Serge Castelier _______________________________________________ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
