Hi all, A while back on a post a need was discussed to communicate with an external app on windows. Sockets proved to be finicky because of blocking, but I was able to successfully accomplish it by using a timer and an error trap. Here is the code: require 'socket' s = TCPSocket.new('192.168.0.1…

[image] On another topic I’m wondering if you’ve tried to leverage the newer (v2017+) classes Sketchup::Http::Request Sketchup::Http:Responce Thanks to @DanRathbun ’s help I’ve managed to implement a much cleaner solution using the Http class rather than a ruby socket. Works like a charm!!! …

I had to set the timer to 0.01 to get the resolution I needed. Also it seems like the max length was 8193 characters.

I’m coming back to this project after letting it lay for some time. Does anyone know of a better way to communicate with an external app on Windows? I’d like to create a C#/WPF solution because I need my app to connect to a PostgreSQL database to read material data and to store and retrieve quote in…

[image] Neil_Burkholder: My extension will be used by multiple users sharing info from the same database. Haven’t tried anything like what you’ve described, but have you looked at the pg gem ?

[image] Neil_Burkholder: Is it possible to install gems in SketchUp? Yes, and pg is available as a ‘fat binary’ gem, so compile tools aren’t required. See Gem.install : Gem.install('pg') You’ve still got to decide whether to use C#'s ORM tools, roll your own, or add another gem. gem env ca…

Sweet. That was easy. Thanks for your help. Now I’ve still got to decide whether to utilize my C# skills or try to learn HTML/Java-script…

Neil, I assume you listed a simplified version of your socket code. Regardless, you might have a look at IO#ready? from io/wait . Also, an opened ended rescue leaves a lot of issues ‘untrapped’, and maybe a timer loop running. Sounds like an interesting project. Given what you’ve said, I’m guess…

Greg, Thanks for your valuable input. The problem I was having was blocking, because SketchUp doesn’t support Ruby threads. I came up with the timer and the error trap to prevent the following error. Error: #<IO::EWOULDBLOCKWaitReadable: A non-blocking socket operation could not be completed immed…

Neil, I wouldn’t put all the blame on SU, it’s a combination of Ruby, Windows, and SU. Ruby doesn’t have the callback/event objects that C# has… I’ll have a look at this later. As to the rescue, what I was referring to was a change something like: stimer = UI.start_timer(0.5,true) { begin …

[image] MSP_Greg: Is the data over the socket intermittent (based on UI actions)? That is exactly the case. It would basically be the same use as the add_action_callback method. [image] Class: UI::HtmlDialog The Ruby HtmlDialog class allows you to create and interact with HTML di…

Is it possible to install gems in SketchUp? If so is the process reliable enough for a distributed extension?
