Antw: Bells and winvnc
>>> [EMAIL PROTECTED] 20.02.2001 05.09 Uhr >>> Folks Correct me if I'm wrong but it looks like: . the RFB protocol defines a Bell message type . the vncviewer for Win 95/98/NT/2000 if it receives a Bell message will, if the local PC has a bell, ring it . winvnc 3.3.3 has no provision for converting a control-G (bel) output by an application on the PC running winvnc into a RFB Bell message and sending it to the client. I've only just 'discovered' VNC. It's just what I need except that I must have the ability of hearing the bell of the remote system on the local system. Before I look at trying to modify the source of winvnc to implement the RFB Bell message, I thought it worth asking whether anyone has already done this. If so, I'd be really grateful if you could send me the details.

multiple sessions
Is there a way to have multiple vnc sessions into one box? If not then is there a way to prevent others from logging on via vnc thus killing your active connection?

You could get hold of the VNC source-code and: 1) Edit the VNCHooks DLL to include a Beep() function, which would simply post a custom "beep" message into the message queue of WinVNC, in the same way as a normal update. Include the VNCHooks DLL in your application and use the Beep() function in place of (or as well as) MessageBeep under Windows. 2) Catch the message inside WinVNC and send a VNC-beep message to all clients.

Firewall problem solved
Just wanted to write a quick note to thank all who helped. I am writing this as we "speak" using port forwarding on my Linksys router. I can't explain why it didn't work before, but it does now. Could have been something I was doing wrong, but I swear I set everything the way I have it now. The ONLY other change I made is that I have VNC running as an app instead of a service on Windows ME, but I can't imagine that made much of a difference. - To unsubscribe, send a message with the line: unsubscribe vnc-list to [EMAIL PROTECTED] See also: http://www.uk.research.att.com/vnc/intouch.html -

Re: Drive mapping?
Drive letters are single characters, so you can extend somewhat further into the ASCII character set, but you quickly run into a problem... The next "letter" after Z is [, which just looks funny ( [:\config.sys ), but probably works. The second character after Z is \, which will confuse the file system tremendously ( \:\config.sys means something totally different...) You can also reference resources directly in most places with the following syntax: \\remotemachine\remotedirectory\FileIWant.txt This does not work from DOS (or at least not DOS programs -- command.com seems to understand it sometimes), but you keep mentioning Win2000, so that may not be an issue. Since you aren't mapping anything, you can do as many of these direct references as you need.

Windows ME has the stupidest networking option I have ever seen -- if it can't detect a functioning network connection, it disables the ENTIRE network stack -- you can't even talk to localhost (127.0.0.1) because the TCP/IP driver isn't loaded. Dunno if it has any effect, but when WinVNC loaded as a service, it might be that the TCP/IP driver wasn't configured yet.

The property added by WinVNC is destroyed whenever the hooks are removed from the system - this occurs whenever you change desktops under NT, and whenever all VNC connections have gone. If a Delphi app ran immediately after a VNC connection had closed, it may well be allocated the same prop number. > >Do the Delphi apps crash only when a > >VNC session is connected, or only when ones _has_ been connected but isn't > >any longer, or both? > > I can happen when the VNC session is connected. I can't tell if it can > happen afterwards too. It may happen while the session is connected simply because Delphi has been run between two VNC sessions and so has grabbed the *old* VNC atom, leaving the new VNC session to use a new one. If VNC had incorrectly left properties atteched to system windows then Delphi would then get confused.

Debian's bootfloppies could be used for this - the boot-floppies package has a set of scripts to build a boot floppy (actually 2 floppies now the kernel has grown so much, but this could be squeezed back down to 1 presumably). This includes busybox, which could be used on its own - there is also a busybox-static package :- Package: busybox-static Priority: optional Section: shells Installed-Size: 872 Maintainer: Erik Andersen <[EMAIL PROTECTED]> Architecture: i386 Source: busybox Version: 0.48-1 Filename: pool/main/b/busybox/busybox-static_0.48-1_i386.deb Size: 403218 MD5sum: ac1713a40ad025896ee112874d3d9ebb Description: Provides a stand alone rescue shell with tons of builtin utilities. BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides minimalist replacements for the most common utilities you would usually find on your desktop system (i.e. ls, cp, mv, mount, tar, etc). The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. . BusyBox-static provides you with a statically linked simple stand alone shell that provides all the utilities available in BusyBox. This package is intended to be used as a rescue shell, in the event that you screw up your system. Invoke "busybox sh" and you have a standalone shell ready to save your system from certain destruction. Invoke "busybox", and it will list the available builtin commands. But busybox does not seem to contain networking commands itself (well it has telnet, but no ifconfig, netstat, route). The boot-floppies scripts require additional packages to build a boot floppy.

Black screen on Win98 target
I saw a number of messages about this in the archives, but no one ever came up with a solution. I hope the debug logs I have will help. Briefly, I am connecting to a target machine that is running Windows 98. The problem is that shortly after connect, the VNC session will hang, and after disconnecting any new sessions have only a blank black screen. The system needs to have the VNC client closed and re-opened to re-connect to the machine. The problem happens in both service and application mode. The problem seems to happen more frequently if I use the JAVA viewer instead of the Windows viewer, though both will eventually cause the problem. When I turned on debugging in the registry, the problem became much harder to duplicate (it took me a week to get it to happen again.)

VNC as single app server
Hi Folks I am sure I have seen a reference to using RFB protocol as a single app front end somewhere - a full function application, not simple like the rfbcounter example. Has anyone integrated a widget library directly with a VNC server? Possibly without keeping a full frame buffer image? It seems one needs to be able to provide some added features to the RFB protocol to support client side resizings (that can be much more intelligently handled by an app than a client that just adds scroll bars), some support for iconisation including animation of same. Don't think the current clipboard feature can provide full drag and drop integration capabilities down the RFB pipe... Anyone using RFB with PDAs? I could not find any other threads along these lines.
