Some tips for customizing RustDesk for Windows (other platforms might require additional changes)

Embedding UI / Enable Inline Builds

In order to include the applicatin's UI resources in the executable, you will need to enable the inline feature. This compiles the application resources (src/ui) into the executable so you do not have to deploy them yourself.

1. Enable inline feature by editing Cargo.toml

   Under the [features] block, find this line

   default = ["use_dasp"]
   

   and change it to read

   default = ["use_dasp", "inline"]
   

2. Build the UI resources (requires Python 3 to be installed)

   Run python res/inline-sciter.py every time you want to build the UI resources again (i.e. every time you modify the UI)

   If it complains that it cannot find python or the command is unrecognized, you need to install the latest version of Python 3 and add it to your PATH environment variable.

Embedding Sciter.dll

If you want a single portable executable file, you can either statically link Sciter, or embed the DLL. Statically linking it requires you license Sciter, which costs money--so I went with embedding the dll.

1. Copy sciter.dll to your project root directory (where Cargo.toml resides)

2. Add the following lines into fn main() in src/main.rs

       let bytes = include_bytes!("..\\sciter.dll");
       fs::write("sciter.dll", bytes.as_slice());
   

   Note: Do not remove the "..\" as main.rs resides in /rustdesk/src, and will not be able to find the file otherwise. Alternatively you can put sciter.dll in /rustdesk/src

   The function should now look like so:

   #[cfg(not(any(target_os = "android", target_os = "ios", feature = "cli")))]
   fn main() {
   
       //BEGIN CHANGES
       //Embed the Sciter.dll file into the exe, and then write it to disk when application starts
       println!("================ LOADING SCITER DLLL ==================");
       let bytes = include_bytes!("..\\sciter.dll"); //since main.rs is in rustdesk/src, we need to go up one level (to rustdesk)
       fs::write("sciter.dll", bytes.as_slice());
       //END CHANGES
   
       if !common::global_init() {
           return;
       }
   
       //println!("Key: {}", hbb_common::config::RS_PUB_KEY);
       //println!("Password: {}", hbb_common::config::RS_PASS);
       //println!("Salt: {}", hbb_common::config::RS_SALT);
       if let Some(args) = crate::core_main::core_main().as_mut() {
           ui::start(args);
       }
       common::global_clean();
   }
   

Hide Console Window

You can toggle the console terminal window by uncommenting line 3 in src/main.rs

#![windows_subsystem = "windows"]

Comment it out to show console window, uncomment it to hide.
