How to pop up the box for entering file address？

Zhenyu Zeng
Posted 1 year ago

Hello, I want to make an interface to do some calculations. In these calculations, I need to import some files. Each time, the file locations will be changed as different users use them. I am curious about several questions:

  1. Can I make an executable program run on computers on which the Wolfram Engine is installed?
  2. When executing this programme, how to pop up a box by which the users can select the local files?
  3. I rarely see the instruction about making an interface by Mathematica. What's the reason? Does everyone use Mathematica just as a calculator?

Thanks

Hi Zhenyu

  1. wolframscript can be used to execute a script file (.wls) containing WL code against a local or remote installation of the Wolfram Engine.
  2. In a notebook one can use SystemDialogInput["FileOpen"] to open a dialog box for the user to select a file. However, it (and many WL functions) require a frontend so it will fail when evaluated in a .wls file. If you need interactivity and visualization, take a look at CDF or the Wolfram Player.
  3. There are many ways to build a user interface using WL. The CDF link above has several examples. For details take a look at this.

Hello, This code

SystemDialogInput["FileOpen"]

can't be run in Wolfram Player.

Or did I not know how to run it?
