1's compliment?

As part of a BCC calculation, I need to "Take the last 2 characters of
the 1's compliment". But I'm having so much trouble with this one
that I'm not even sure how to word the question correctly.
Essentially I have ASCII code for 12 characters. I need to sum
the HEX values of these 12 characters. I then need to convert
this HEX value into a Binary number and "flip" all the bits. Then
add one, and keep the two least significant digits.
I've spent the last four hours trying different things here, and I'm
getting nowhere. Any suggestions are greatly appreciated.

It's confusing for me too KC.
BCC apparently stands for Binary Cross Check.
To send a serial command to this particular controller (IAI RCP2) I
need to add the ASCII codes for 12 data characters. This will
give me a HEX number. (IE 2FA)
I then need to convert that number to binary and "flip" all the bits. (IE any zero becomes a one and vice versa)
Then, add one.
Then convert back to HEX and keep the two least significant digits.
Although this seems like a pretty convoluted way to get a check bit, it
does work for me when I do it manually on a calculator.
I'm very new to this type of communication, so I'm not sure if this is
what would be called a "twos complement" or not. So far nothing
I've tried has worked correctly for me.

Sorry! I have not explain it clearly.
To solve it , you do following :
1. locate stdarg.h ( or find /usr -name stdarg.h ), assume you find a stdarg.h in /usr/lib/gcc-lib/XXX/XXX/include/stdarg.h
2.ln -s /usr/lib/gcc-lib/XXX/XXX/include/stdarg.h /usr/include/stdarg.h or cp /usr/lib/gcc-lib/XXX/XXX/include/stdarg.h /usr/include
( above 2 step was to make Pro*C can find stdarg.h in /usr/include )
3. for file stddef.h do like step 1,2
4. append a line in your Pro*C config file:
CODE=ANSI_C

WRT54G - Is there anyway to add a separate VPN/Firewall device to complement this product

I have a WRT54G v.2 device and I hate to throw it out. My dilemma is that I'm in need of a VPN/Firewall device as well. So I would like to know if there is a device that I can purchase from Linksys that will provide the VPN/Firewall features as a complement to my existing WRT54G? I'd appreciate any info someone might be able to provide.
Regards.

Hi,
you have options between the RV series of VPN routers and the BEFSX41 and the BEFVP41.however you will have to change your network a bit.Your main router will have to be either of the VPN routers.The DHCP of the wrt will have to be disabled and you will also need to change the ip of the wrt from 192.168.1.1 to 1962.168.1.2
The connection will be.modem to internet port of the VPN router and then from port 1 of the VPN router to port 1 on the wrt.Do not use the internet ports of the wrt.

Bit Complement in an Expression Node

I can use bit complement in a formula node but not the expression node. The
"~" tilde is the only text in the expression node. The error is "~#" with
# being the error. The input is a U8. Thanks in advance for any help.

Hi Catherine,
I've tried your suggestion earlier and tried it again after your
post but it still doesn't work. I am new to expression nodes so maybe my
syntax is incorrect. To do the same in C language I think it looks like
this: "a = ~ b;". I made a picture and a copy of the error. Let me know
if you see anything wrong. Thanks!
Error on line 1 is marked by a '#' character: "~#"

I hope this question is not too simple. Does your CLASSPATH contain the path to the beans package .class file location, or the jar file that contains them?

Problem in compling with G++ compiler

Hi ,
I have written one application in java which is calling the C API and after processing it is giving result to the Java application.
Now i have changed the extension of the C API to .cpp then i am compiling the same source code using the g++ complier but it is giving error in the function where i am calling my Java function in C API .
Can any one tell me is there is any thing wrong i am doing ...
For compiling the C API i am using the command (It is compling fine )
gcc -o libpixim.so -shared piximImager.c -I /home/java/include -I /home/java/include/linux
For compiling the C++ API
g++ -o libpixim.so -shared piximImager.cpp -I /home/java/include -I /home/java/include/linux
But it is giving error ....

I know both langugaes are not same but c is a sub part of C++ if it is compling in C then with C++ complier it also should compile.
I am found the solution for that
ie
g++ -o libpiximImager.so -shared -I /home/narendra/javatest/j2sdk1.4.2_15/include/ -I /home/narendra/javatest/j2sdk1.4.2_15/include/linux/ -lc
I have miss to put the -lc option

menuSelected is a Abstract method. That means if you implement the MenuListener Class you SHOULD define the menuSelected() event.
I am not correct with the Method names but logically it seems that tis is the problem.
Another thing, use setJMenuBar() instead setMenuBar()

Complement with Airport Express?

Greetings,
I have a Cat6 cabled home. The outside internet is pulled inside to the laundry room on the first floor where it then disperses into 4 other rooms. I currently use a Netgear WNDR4500 1000GB wirelss router in this area to share, but unfortunatley upstairs the wireless signal has some interference over the 5G/2.4G.
For the upstairs media room I use a 1000GB switch to connect other peripherals such as PS3, Apple TV, TV etc, but I was wondering if it was possible to complement with an Airport express to strengthen WiFI since the other routers is "hidden" in a laundry room? If so, do I connnect the Airport Extreme to the LAN port and just have my computers find the device, or do I have to add a completely secondary network in my home? (In other words, is it better to turn off the WiFi on the Netgear router and just use it as wired and use the AE as Wifi only)
Do I need to create to different gateways? Confused...

You have me confused too......just kidding - you have a somewhat complicated issue so I will just throw out some thoughts and see what sticks - first of all, you can't strengthen a signal either wirelessly or via ethernet - it would be the same or less strength depending on many factors - you could extend it to a different area for more coverage - but keep in mind that Apple products can't extend a non-Apple router wirelessly - they can only join the network so you have ethernet capability but no wireless brodacast - you can however connect to the router via ethernet and "create" a wireless network in a remote area with the your same network name or a different name - are you really confused now? - if so do this - to have a true roaming network, you need to replace the Linksys with the Extreme and use additional Extremes and/or Expresses wired and/or wired in remote areas - this is the Ideal setup in my opinion - see what you think and get back to me.

One more question. I search through the posting archieve and found out a reply by Alison Stokes (Oracle iFS Product Management) to "Changes in *.js and *.jsp files are not effective", saying that
"If you are attempting to modify the jsps comprising Oracle iFS' Web UI, this is not supported for release 1.0."
Does it mean I can't modify the container.jsp file that defines the iFS's WebUI? Actually, I was asked to modify the looking of this body frame to contain more custom attributes. Can I do that?
Thanks.

1's compliment?
