There are three security environments that address these issues today.
1. The program is restricted to run in an environment that protects the operator. An example of this would be Java applets. There is no way that a Java applet can write to your hard disk. 2. Signed code. This is Microsoft's mechanism for authentication and all it really does is prove that the program you are running is written by the author and has not been changed or replaced. Many Active X controls you download over the net bring up a warning message (if you have you security setting on medium or above) that asks if you really want to install and run this program. 3. Open source has become a very reliable way of ensuring that code is good. However this only works with people who understand the code they are reading. The bottom line is that the industry does not have a foolproof way of ensuring security. I say all this just to further support Ronald's points. Baggis, I had no idea that English was not your first language.

Yes there is.
AW supports the idea of a "privileged password" that you can use to allow other people to build under your name. So, you might login using your name and normal password and then someone can tell you their privileged password so that you can build something for then under their name (cit number). You have to specifically set this password up. It does not default to your normal password. Run the AW browser and check your settings. There is a field there to enter one. It is this privileged password that is required for bots to login to a universe. Good luck [View Quote] Please helpMar 11, 1999, 10:03am

I wouldn't say that the idea is "not bright". Indeed it is an excellent idea in
certain situations. You could use a small object like the little cup. That would significantly reduce the likelihood of hitting the wrong avatar. Use a world that disables the shift key. So for ejecting people from a soccer field it could still work. The players would just have to be careful not to kick the cup. Oh, for a bucket object to make the joke complete. A cool pace to use it might be in a maze or haunted house. You could play some really cool games with people.

The way I eventually simplified this include business is to put all the AWCPP
include files into one AWCPP.hpp file. By doing this I loose a little compile performance, including files that aren't always necessary, but I am assured that I have all the correct include files in the appropriate order. There is nothing more tedious, to my mind, than chasing down include file dependency problems. I am not sure which version of AWCPP you are using Tom but the latest version, 0.4, has AWCPP.hpp included into AvatarMe.C. The AWCPP.hpp file contains the appropriate Avatar.hpp and AvatarMe.hpp include files. If I had a perfect object model it should tell me which classes were dependent on which other classes. It just seems like so much work to go through all that when one can put them all in one file. It is also a simplification for people who wish to use the AWCPP.lib. They just have one include to add to their code to allow them to use any of the classes. In thirteen years of programming I have never been happy with my include file strategies.

I used "teach yourself C++" 5th edition. by Al Stevens, MIS: Press.
Its got the attached CD rom with all the sample code on it. Having been a programmer for 13 years now I can't tell you if this is a great beginners book. What you need to do is go to a good store and scan all the C++ books and wait for the feeling of "hey this looks easy...". It all depends on how you like to learn and what level the books pitch to. One thing to look out for are the update books. There are number teaching books that just teach you about the updates to a particular package. Like the "Unleashed" set of books. I have "Visual C++ unleashed 4.0" and it was good for learning how to use the extensions to VC++ since version 3.0 but not to learn C++. I would recommend a learn C++ book and then if you want to learn your particular IDE get one of those books aswell. There are lots of web sites if that is what you prefer. I just like books more. http://www.cpdee.ufmg.br/cursos/cpp/tutorial.html Best of luck. [View Quote] > I wrote 100,000+ lines of C++ code but I learned with "Cut and > paste" .

Oh yes, another great tip. Check out http://www.mcp.com/ and the personal

Ofcourse you are limited to MacMillan books but they have a lot of great C++ learning books.

An interesting question. If, by JDK, you mean the Sun Java Developers Kit then
none of the software you mentioned is required. All you need is the Sun JDK. javac is the java compiler and java is the interpreter. Since you are posting to the AW SDK newsgroup I should probably assume that you are trying to work with the JAVA wrappers that have been developed. It is my understanding that since the latest release that no C++ code that needs to be recompiled to get it to work. But then I could be totally misunderstanding you question.

What are you trying to do?
On the Sun JDK the -X option is for non-standard arguments and their interpreter ("java") does not include a runGC argument (jdk 1.2). They have an incgc to indicate an incremental garbage collection process I don't know if that is the same. All DLLs can be called from Java code using JNI interface. Microsoft has an slightly different interface called RNI but it does the same thing just not as portable. If you are trying to create a DLL from Java code then I would look into VJ++ which has some cool programs for wrapping the jvm in a com object and the like.

Edward Sumerfield, esumerfd at msn.com http://members.xoom.com/esumerfd [View Quote] Make this my default idJun 26, 1998, 4:41pm
Two small wishes.
When you login as a citizen the "Make this my default id" flag is set to true. This should be false. I have multiple people login in to the same browser and it is a pain to have to be re-logging in after it has automatically logged you in under someone else's name. With the flag set to false and no citizen entry in the ini file it will prompt me to login each time the program is run. The second point is a bigger one of storing citizen specific information under the citizen instead of in a general area of the ini file. The home location, last avatar used and the like should really be citizen specific. Edward Sumerfield, esumerfd at msn.com Re: Mirrors.Jul 10, 1998, 12:14pm

solution sounds good. What do you mean about creating a "bot" so that you can see your avatar? [View Quote] Mirrors.Jul 11, 1998, 2:17am
It sounds really difficult but is it possible to create a mirror object in
AW. The main reason I ask is because I am trying out different avatars but can't see the faces. I could download them and use rwmod or something but it isn't that important. Edward Sumerfield, esumerfd at msn.com http://members.xoom.com/esumerfd Mirrors.Jul 13, 1998, 4:19pm
When you run the second aw it just brings the first version into focus. You
would have to have two separate installations so that you don't get any cache corruption but even with two separate executables in two separate installation directories it will only run the one program. I don't know if this is a feature of AW or windows. Maybe someone knows how to get around this.

The problem of movement control is solved in 90% of 3d programs using a

Maybe the telegram interface could be replaced with a mail interface, full
smtp and pop3 support to a telegram window in the aw browser. Installation would be easy if you just insert Microsoft's output express into one of the windows. Of coarse, not all mail readers are quite as friendly. That would give us much more communication flexibility and allow us to remain in the same environment. The browser can to the translation from citizen name to aw mail address if need be although it would have to deal with specific AW mail servers so the citizen name could be setup as the mail address. How about an in world mail reader. It wouldn't be hard to make a "mail sign" that allows you to read your mail from within the world. I dare say you could go as far as making a "send mail sign" as well so that you can send mail from your world. I may be getting carried away here. So we have a few new commands that can be put on any object that supports text. activate mailreader activate newsgroupreader Edward Sumerfield, esumerfd at msn.com http://members.xoom.com/esumerfd [View Quote] saving telgramsJul 16, 1998, 6:40pm
I agree I did get carried away but consider the amount of coding involved
with implementing the mail standard compared to implementing a proprietary standard. Most of the work is already done for you. There are hundreds of smtp and pop3 controls on the market today that could easily be plugged into the browser for retrieving "mail telegrams" for displaying. Maybe phase one should just include the display of the mail in the chat window like today's telegrams. With this expandable architecture in place it wouldn't be hard to add a save feature or even putting the text onto a sign object. I believe in a direction that moves as much functionality into the 3d world as possible. The future of this world experience is critical to its success.

I agree. Animate does not work with URLs but flower8 is a fixed picture
using the flo8.jpg texture, so I don't think that that is relevant. The one sided picture is a problem though. You can put two of them back to back but you still have the problem of looking at the flower at an angle. There is the "axisalignment zorienty" (thank you Eep) in rwx that makes an object always face the viewer. I don't think there are any animate type objects that have it though. So maybe this has resolved into another wish. To allow builders the create their own textures on objects that always face the viewer can we have a set of animate??.rwx with the axisalignment zorienty line in them? Stop the presses. I just downloaded the flower8.zip to check my facts ModelBegin ClumpBegin AxisAlignment ZOrientY Vertex -.05 0 0 UV 0 1 Vertex .05 0 0 UV 1 1 Vertex .05 .1 0 UV 1 0 Vertex -.05 .1 0 UV 0 0 TextureModes null Texture flo8 mask flo8m Quad 1 2 3 4 ClumpEnd ModelEnd It already has the "AxisAlignment ZOrientY" thingy so why doesn't it always face the viewer.

Telegram Rediction To Email AddressJul 22, 1998, 4:23pm
The telegram system needs to be updated to a full mail client. They are
already embedding explorer in the right hand window. When you click the telegram button it would just switch over to a mail control instead. It would talk to an smtp server to send things out and poll a pop3 server to read telegrams in. A simple, already coded semi-bug free protocol that everyone knows and loves. I put this wish in with another thread but it sounds like you are coming around to it here as well. Edward Sumerfield, esumerfd at msn.com http://members.xoom.com/esumerfd [View Quote] Telegram Rediction To Email AddressJul 22, 1998, 7:58pm
The issue is not so much the interface, you can build your own front end.
After all, if you are going to implement telegrams then you are implementing, not only a custom interface but also a proprietary protocol. People are now asking for features that are already built into mail systems. If you want to modify the interface a little to make it more AWB friendly that shouldn't be a problem. MSIE doesn't actually have a mail client embedded. It uses the windows default mail client interface to activate it. You say we already have mail but we don't have the mail addresses of anyone we talk to. The universe server with its nice little list of people has all that information. An AW mail interface would bridge that gap. My original thought was along the lines of extending the 3d experience to mail reading. It would be cool to be able to put your mail onto a sign object with a next and previous button. This may be a little enthusiastic to start with but building a tighter coupling between the browser and the mail protocols would be a great first step.
