• Show or hide elements in PDF via Javascript

  - by Boldewyn

  In PDF files it is quite easy to interact with form fields via the Javascript API. Is it possible to do this (specifically showing/hiding) to arbitrary elements on a page? Say, not just form fields, but text, graphical elements, embedded images... Is there an API to interact with those? If yes, how do I identify an object?

• Does it make sense to have several UDP ports ready? Will packets be dropped?

  - by Gubatron

  I'm coding a networking application on Android. I'm thinking of having a single UDP port and Datagram socket that receives all the datagrams that are sent to it and then have different processing queues for these messages. I'm doubting if I should have a second or third UDP socket on standby. Some messages will be very short (100bytes or so), but others will have to transfer files. My concern is, will the Android kernel drop the small messages if it's too busy handling the bigger ones?

• Perforce: How do I p4 integrate a local uncommited changelist?

  So here's my scenario: I have two projects projectA and projectB. A branchspec auto-integrates projectA to projectB. Now, I have a changelist which modifies some files in projectA -- I have not committed/submitted this changelist yet. I'd like this changelist to go into projectB only. Doing a p4 integrate -b branchspec -c changelistNumber shows "All revision(s) are integrated." How can I integrate an uncommitted changelist?

• In ADL_Display_ConnectedDisplays_Get() from ATI's ADL Library, the out parameter lpConnections is co

  - by animesh

  The API defined in the ADL SDK manual reads: int ADL_Display_ConnectedDisplays_Get(int iAdapterIndex, int* lpConnections) They say that lpConnections is the pointer to the bit field indicating whether the output connectors on the specified adapter have devices physically attached to them. This information is exactly what I want but nowhere in the documentation I could find any data on what the various bits in the lpConnections obtained might mean. I also tried going through the header files but found nothing relevant on this. I know this is very specific to but can anyone here answer?

  - by Cheeso

  Just what the title says. Given a build file (.csproj or msbuild.xml or whatever), I'd like to run a msbuild command that lists all the available, defined targets. Does that function exist? I know I could do an Xpath search or something, on the build file, but that wouldn't get included files.

• rsyncing - ignoring checksums

  - by paulj3000

  Trying to copy a bunch of data over and time, unfortunately, is of the essence. I'd like to do an rsync of all the data in one direction, pretty much rsync just clobbers what's over on the destination server. Is there a way to do an rsync and just say, "overwrite all files" Is there a better way of doing this? We're talking 500GB of data that only has to go in one direction.
