Copy/paste functionality for a TUI screen Ask Programming |
| Copy/paste functionality for a TUI screen Posted: 21 Jan 2022 10:53 PM PST I don't know if this will even make sense at all but maybe someone could point me in the right direction. I am an infrastructure person fyi. At work there was a home-grown mainframe application written in "EGL" which was somehow re-platformed to x86/rhel. In the old environment, it was accessed using Rumba Client with TN3270 emulation and apparently this added a lot of functionality including the ability to copy and paste easily. It is used for data entry and reporting. The migrated application is a java .jar file which is run from the workstation or app streaming service (ex: Citrix) and talks directly to a database. There is no "application server", other than one that runs jobs against the database. I was told while the project was being completed rather than redo the application completely and build a web app/gui they replicated the different screens that the user goes to as a "TUI". Someone asked me to check whether the client is setting up a listening port and might be both a client and server but it isn't, it's not listening on any ports just making an outbound connection to the database. Normal copy and pasting isn't available such as control c/control v wherever you want, which was possible with Rumba/Mainframe. Some workaround type stuff was put into the application where it will read or write to the clipboard in certain circumstances using key combinations but it is not full featured. It was signed off on, but now that it's in production the users are complaining. The manager of the application team seems to feel that there is some software out there that will somehow solve this problem and provide the same kind of functionality that Rumba did, but for his java/jar file. Originally he was asking whether our software streaming tool could solve the problem, and I had to explain that it isn't what it does, and that they probably needed to add the functionality to the code. Which he says is probably too major a lift, and that they cant re-write much code. Does anyone have any clue if it's possible to accomplish something like this with different software, or any suggestions (other than quitting)? Yes I understand I shouldn't necessarily be the one to even be looking, but sometimes if I don't people will try to desperately grasp at straws and set up 10 meetings with vendors that I instantly know won't help. That's just how my org works. Sorry for the ramble, any help would be appreciated. [link] [comments] |
| Posted: 21 Jan 2022 07:16 AM PST For some reason VNC seems to be the most universal remote desktop protocol even though it's known to be pretty slow. It works on all operating systems and since it's open source it has pretty accommodating support, for example RealVNC is one of the better iOS remote desktop apps because it has good command buttons like CTRL and CMD. I know of absolutely no similarly ubiquitous remote desktop protocol which uses some more modern, faster protocol. I've heard of tons of proprietary versions - Duet Display, Jump, TeamViewer, AnyDesk, Chrome Remote Desktop, etc. Some of them are good in certain ways but they also have limitations you can't get around because they're closed source. Chrome Remote Desktop on iOS drops really fast in the background and has no command buttons; otherwise it's quite excellent. It's pretty fast but I'm curious if something even faster is theoretically possible. I feel like VNC needs an upgrade or something. A new, fast, effective, universal, free open source remote desktop protocol, working on all operating systems. Is anybody working on something like that? Thanks very much [link] [comments] |
