<![CDATA[How notepad ++ recover file information from an 'web' exploreur?]]>Hello,

I’m looking for a solution to recover the path of a file or a folder during a drag and drop from a web exploreur (page : “file:///C:/…”).
When I drag and drop a folder into the notepad ++ application, in a file, the path is automatically written. How is it possible? What’i the attribute to call?

I try to code a personnal application and I worked on this since severals days, without success…:(

Here is my trial (one of the numerous :D) :

<body dir="ltr">
<input type="file" accept="image/*" onchange="loadFile(event)">
<img id="output"/>
<label id="test"> test</label>

<div>
	<iframe draggable="true"  ondragstart="drag(event)" id = "choixdossier" title="choix dossier" src = "file://C:/" importance = "high" width="600" height="600"></iframe>
</div>
div id="drop_zone"  ondrop="drag_drop(event)" ondragover="return false"  >
</div>

<script>
function drag(dragevent) {
console.log('drag...?');
    dragevent.dataTransfer.setData("text", dragevent.target.id);
    dragevent.target.style.color = 'green';
}
function drag_drop(event) {
    event.preventDefault(); /* Prevent undesirable default behavior while dropping */
	
    var data = event.dataTransfer.items;
    console.log('data : ',data);
    console.log('getData : ',data[3].getData("text/uri-list"));
    data[3].getAsString(function (s){
			console.log('s');
			event.target.appendChild(document.getElementById(s));
			});
		
}
</script>

Thanks a lot for everyone who can help me (I know, I’m a beginner…:( )!

I feel like a beginner and you’re right, I probably misunterstand the differences between web and desktop developpment. Thanks a lot for the links, whose I will read with attention and I hope that will help me to find the solution!
( for the joke, I,ve tried to find what I want in the code source but I’m not gifted apparently :D)

Taking you at your word: You can look in the Notepad++ source code.

But this isn’t a Notepad++-specific concept, so you might want to search elsewhere, too.

A quick search for “win32 api drag-and-drop” on the interwebs shows me lots of reasonable answers, the first three (for me) being two canonical Windows documentation sources, and a SO question which seems to match what you’re trying to do:

Based on even the names of those links, if I were trying to find the Notepad++ implementation of drag-and-drop files, I would start here

-–
But returning to your statement,

I would like to understand how notepad ++ is coded to implement this function

Given that statement in your second message, I am not sure why you originally posted a bunch of HTML+JavaScript code in your original question.

The way you code a drag-and-drop file upload for the web is completely different from the way a pure-Windows application like Notepad++ implements it. If you are really trying to find out how to add a drag-and-drop file upload to your website, then looking at the Notepad++ source code or the links I found for you above won’t help. Instead, you should search for instructions on how to code drag-and-drop file upload for a website. And if that’s your real desire, it is completely off-topic for this forum.

So, I would like to understand how notepad ++ is coded to implement this function (copy the path of a file when drag and drop from a navigator window, ‘file:///c:…’). So I will perhaps be able to do the same process for my code ;).

Again, I do my best to not disturb you, your site and the developpers…Sorry by advance if this message don’t respect your rules (but I hope it does…).
