Is it possible to download a file with dialogue?

[Toto]

Good morning to all,

I'm trying to download a file from my server to the user's computer. And you may specify where it should be downloaded.

Is there any way to do this?

I'm with:

 

window.frame.openDialog({
    type: 'save',
    title: 'Save...',
    multiSelect: false,
    dirSelect:true,
    initialValue:'c:\\Program Files'
}, function( err , files ) {
 
   var http = require('http');
var fs = require('fs');


var file = fs.createWriteStream("image.png");
var request = http.get("http://miserver.com/image.jpg", function(response) {
  response.pipe(file);
});
});

That code I save the file, but not where the user has indicated. Also, I can not know how much has downloaded ... Is it possible?

Hehe .... thanks for reading

Hi Toto,

I found the following on stack overflow: http://stackoverflow.com/questions/4771614/download-large-file-with-node-js-avoiding-high-memory-consumption. You can also see the following answer to get the total number of bytes you need to download: http://stackoverflow.com/questions/18323152/get-download-progress-in-node-js-with-chunks.

So while you are downloading you can count the number of bytes you have gotten with data.length and update a variable. Then in appjs you can update a particular div or span with that number, in deskshell you would send a message over the socket to the browser and it could then update the gui.
