• Command prompt print dialog command

  - by wrongusername

  Is there any way a C++ commandline program on Windows can produce a graphical GUI print dialog for printing to a printer, just like usual GUI programs? I've combed through this webpage and it seems there are only commands that print files in the background to a pre-determined printer.

• Java + Eclipse: Synchronize stdout and stderr

  - by Martijn Courteaux

  Hi, I use Eclipse. When I have an application like this: write 20 times 'Hello World\n' to stdout write 'ERROR\n' to stderr write 5 times 'Hello World\n' to stdout The output looks many times like this: Hello World Hello World Hello World Hello World Hello World Hello World ... Hello World Hello World Hello World ERROR Is there a way to synchronize these two output streams? Of course without waiting a few milliseconds after the block of 20 times Hello World and waiting a few milliseconds after printing ERROR.

• Running compiled squid [proxy] on windows

  - by user683595

  I have downloaded latest version of squid and tried to compile squid on windows according to http://www.piececode.com/other/compile-squid-2-7-on-windows/ , I changed c:\squid to c:\squid2, because had a precompiled version in there. When I run c:\squid2\squid.exe , squid.exe -v , squid.exe -i , squid.exe -X , as I tested these parameters, it will be exited quickly without printing anything at all. Why? I found where the system doesn't return 0 and quits, it's in function WIN32_Subsystem_Init . Thanks!

• Drawing lattices online

  - by lavabo

  This isn't really a programming question but... Is there any way to draw online a lattice for a material, like a compound? i.e. a 3D gridlike pattern? I know there are some applications for drawing mathematical lattices, but the notation to me is unfamiliar - are there simply programs or applets or something for drawing lattices like in a compound?

• DNS NS and domain clarification

  - by thejartender

  I am really trying to get my home web server up and I don't seem to be succeeding. My web server withing my host system is running my web application and is viewable at the current isp ip 88.89.190.171 over WAN indicating that the webapp is fine and that router ports are forwarded. I have set up a DNS on this system with a single name server in the network and I manage to ping it with ping ns.thejarbar.org I have registered this private name server at my current hosting provider. My domain (thejarbar.org) is obviously registered and I have pointed it to my name server. My question here is if it is simply a matter of waiting on propagation for me to be able to ping my domain? Another way of asking this is if the fact that my name server is discoverable indicates that I have set it up correctly to be used? I have tested with dig and dig -x on my host and have A records for the name server. The server is not the Authorative server so I am concerned that this may be the reason why my site is not discoverable. Is there anything else I may need to so still? I only have one ns. currently, but should this succeed I will be purchasing a more stable secondary system to host my development applications. This is my best chance at getting work (freelance development) due to illness) and this I feel is the last step I need to succeed. Please note that this is temporarily a home server and I will most likely be using it as part of a professional setup very soon I will likely have to repeat this question therefore in a prefessional context in a few weeks as nothing will be different other than the fact that I am going to have a server running elsewhere. I am using bind9 and Ubuntu 12.10 and my records are: $TTL 3D @ IN SOA ns.thejarbar.org. email. ( 13112012 28800 3600 604800 38400 ); thejarbar.org. IN A 10.0.0.42 @ IN NS ns.thejarbar,org. yuccalaptop IN A 10.0.0.19 ns IN A 10.0.0.42 gw IN A 10.0.0.138 www IN CNAME thejarbar.org. $TTL 3D 0.0.10.in-addr.arpa. IN SOA ns.thejarbar.org. email.

My localhost IP is 10.0.0.42 I wish for this to be my host and name server.

• Exact textual representation of an IEEE "double"

  - by CyberShadow

  I need to represent an IEEE 754-1985 double (64-bit) floating point number in a human-readable textual form, with the condition that the textual form can be parsed back into exactly the same (bit-wise) number. Is this possible/practical to do without just printing the raw bytes? If yes, code to do this would be much appreciated.
