[SOLVED] Drag and Drop flies including those in Directories to an edit box?

mdwerne · March 5, 2018

So here is my script thus far. I would like to enhance it by adding the ability to drag/drop, and list, not only files, but also files within folders (the folder names can be omitted). For example, if I were to drop the Windows directory on top of the edit window, all files contained within, including those in all the sub-directories, would be listed. Hopefully seeing the GUI will clarify what I'm trying to achieve.

Thank for any suggestions!

Any suggestions? Sadly I've just reached the limitations of my skillset, and so far I can find any previous posts that will point me in the right direction.

doesn't compile. where did you get servicecontrol.au3 ? I was puzzled about your post, and I can't run it to "see what you mean". when you post code, please tell us where to get the custom udfs that you use or provide links.

Edited March 12, 2018 by Earthshine

mdwerne · March 15, 2018

Thank for your reply Earthshine. It turns out that the servicecontrol.au3 udf is not needed for this example. I have commented it out in the code above if you still have some time to give it a try.

Again, thank you for your reply.

Hi Bilgus,

Thanks for taking the time to poke at this, it's definitely closer than I was before. Unfortunately it seems to be ignoring the files at the same level as the sub directory that is being enumerated. And I don't see how to make it recurse through multiple levels of sub directories. As an example of what I'm after, dropping this folder structure from the root of C:\

File1.txt
File2.txt
Folder1
    File3.txt
    File4.txt
    Folder2
        File5.txt
        File6.txt

Would produce this list in the edit box:

C:\File1.txt
C:\File2.txt
C:\Folder1\File3.txt
C:\Folder1\File4.txt
C:\Folder1\Folder2\File5.txt
C:\Folder1\Folder2\File6.txt

Only the filenames with their full path are displayed...no folders.

Thanks again for looking at this, way above my current skill set.

-Mike

If i understand that you want, look at the line

$aList[$aList[0][0]][0] = $sFile ;if you want full path.. $sPath & "\" & $sFile

Bilgus · March 22, 2018

If you are going to be dropping whole drives a few changes need to be made

One we need a way to limit the recursion not sure of the limit but there will for sure be one.. Autoit will bail if you reach it

Two is it could take a while so you need to inform the user somehow

I just put in a message box you'll probably want a status item and to change the cursor to busy etc..

WOW, this looks great, thank you both, Bilgus and kaz!!

I may be able to take it from here, but feel free to jump back in if you see an easy way to switch from a list control, to an edit control. I allow users to not only drop files in, but also type them in (but I may just change that).

Just so you know, I would never drop a whole drive on the GUI, this utility will be used in conjunction with a CD burning program. Typical use case is the customer would drag the files/folders to be burned to a CD, and then run this utility, drag the same files to the GUI to then "log" the files that were burned. Yes, not the best process, but it's what I've been asked to work on.

So if making this an edit control is pretty trivial, then I can give it a shot, otherwise I may just keep what you've done with the list control. At this point, I see no reason why they could not just drag and drop additional files, and if they make a mistake, "clear" and start over.

You guys rock!
-Mike

Bilgus · March 22, 2018

You could either set up the listbox to allow selecting items + a delete button and an edit control to type or drop the files in

or a treeview or even better add a FileOpenDialog

Great suggestions, thank you!!
