Drag and Drop - the other way around

motionman95 · February 17, 2009

Since I didn't get much help on my last thread (due to an ill explained problem, I guess) I will try to explain what I'm needing help with. Here goes...:

I'm making an app that will convert font files. Here's how it works:

1.) The user will drag in the file(s) that they want converted to a certain part (a group control) of my GUI window.

2.) The file will be converted.

3.) The user can then use the second part (a group control) of the GUI to "drag and drop" from their converted "file(s)" to the desktop, or the location they choose, and have the converted file copied there.

I'm really need help with number 3. 1 & 2 I've been able to do, but number 3 is proving to be difficult, because I'm not that advanced enough to accomplish it. I'm trying to have it so they (the user) can drag and drop from my GUI window to the desktop (from my GUI Window), and the files appear on their desktop. I've only been able to drag and drop from the desktop to my GUI window.

Any help with this guys? Threads, Ideas...etc? Thanks!

EDIT: I've found a C# code sample that shows exactly what I want to do:

I'm sure there are a lot of people who would be happy to help you, as I would, but I don't know what you are dealing with. You haven't told us what there is in your gui that we are selecting and dragging. Is it an item in a list box, an icon in a list view, a line in an edit, a label, an icon or something else?

If you tell us what you want to drag it would help, and what might be even better would be to show us what you have so far if you can.

motionman95 · February 18, 2009

They aren't dragging anything. They need to think that they are "dragging" something, so that when they do drop on the desktop, the converted file is copied there.

I died a little inside on that one.

Sorry man, no idea.

motionman95 · February 18, 2009

Would this help?

The desktop is a process, isn't it? Shouldn't there be a way to detect when something is dropped on it?

Bert · February 18, 2009

Since you won't show us your code, there isn't much we can do to help. Sorry. You need to post what you have so far. Then we can get a MUCH better understanding of what you are attempting. So far, we do not understand what you are trying to do.

motionman95 · February 18, 2009

Thanks for the reply, Volly. If I did post my code, I don't think it would help. The code I have now has nothing to do with this problem, I simply have no idea how to go at this problem. I think this link will help you guys to understand what I'm trying to accomplish better than me trying to explain it.

If you have code that you can drag a font file into, and you have conversion code that can create a converted font file, why not post that so others can work on adding the ability to drag the converted files to the desktop. That way we can play with something and not have to create the initial part from scratch.

Here's the code my app - I haven't worked in the font converting method yet, but I already know how I'm going to do it. Also, this code only has drag and drop to theGUI, and not drag and drop from the GUI to the desktop.

Sorry, motionman. The clipboard support in AutoIt is limited compared to some others, same with drag and drop operations. Noone, has done this before so all we can do is link you to source code in another language.

Without the jpg I don't know what your gui looks like.

You could have a list box which you drop items into. Then the user can see the items he's dropped and which have to be converted.

The converted files can be put in a second list box and then the user could drag items from there.

It might be easier to simply select an item and have a button or menu to save the file to the desktop.

You could save the converted files in a special folder then show that folder so the user could drag and drop the files from there to wherever he wanted then you have no drag and drop code to worry abouit.

motionman95 · February 21, 2009

Well, since it isn't going to work that way, would it be possible (as far as dragging into an explorer window) to just use the handle on the explorer window, and look into whatever text input it is that holds the current directory?

You could have a list box which you drop items into. Then the user can see the items he's dropped and which have to be converted.
The converted files can be put in a second list box and then the user could drag items from there.

Is there a way to do that?

I have an idea - would it be possible to get the user's x and y of their drag and drop, and then simulate the exact same one?

Also, would embedding a windows explorer into my a GUI allow me to drag and drop to the desktop?

DOn't understand that.

Yes, but it might look a bit messy.

$gg = GUICreate("drag  from")
GUISetState()
$folder = "c:\temp"
shellexecute("explorer.exe",$folder)
sleep(1000)
$hExpl = wingethandle("C:\temp")
WinMove($hExpl,"",0,0,200,200)
$OrigParent = DllCall("user32.dll", "int", "SetParent", "hwnd", WinGetHandle("C:\temp"), "hwnd",$gg)
while 1
    sleep(90)
if GUIGetMsg() = -3 then Exitloop

WEnd
DllCall("user32.dll", "int", "SetParent", "hwnd", $hExpl, "hwnd",$OrigParent[0])

motionman95 · February 21, 2009

Awesome! Is it possible to remove the tool bars and the right-click menu?

Edit: By "I have an idea - would it be possible to get the user's x and y of their drag and drop, and then simulate the exact same one?" I meant that could I get the x and y of the first press of the drag and drop, then the x and y of the release?

I don't understand that again.

This is a way to do something like what you want.

You can drag a file to the left hand listr box. SDelect it the press the "process" button and it will be copied to th eright hand list box. From there you can drag it to the desktop.

It work, but it's awfully slow. Can it be speed up?
