View 3 RepliesGoogle Chrome has a handy feature where I can click a download link and drag it into a Windows Explorer window, and then drop. After dropping, Chrome then downloads the file and it appears where I dropped it.
I would like to be able to drop from Google Chrome into my application, but it seems it isn't so simple. I have a DataGridView called gridFiles, and the following code:

EDIT: So it seems that with regular URLs, I do get the proper dragged-in UniformResourceLocator format. The behavior I am seeing occurs with the download links in Gmail. It probably happens elsewhere, but I am not sure. When a gmail attachment is dragged from Gmail into my application, I get a FileDrop.
Doing some more digging, it seems that Gmail is using the download_url attribute of the anchor tag. I have never heard of this before. Perhaps this is just an extra property they have added?
In any case, since my application will primarily be used with e-mail attachments, I need a way for the phantom FileDrop to work, as stated above. I am unable to use Spy++. It doesn't seem to show any messages when drops occur.
Edit #2: Here is more information on how Gmail utilizes drag/drop for files: [URL]

drag and drop nodes within the same tree (not between trees) when users drag and drop nodes within the tree, give them the option to move the original node to a new location within the tree OR to just copy the original node in a new location (seems complex but I have a month to figure this out). change the system default blue highlight for selected nodes to another color change the system default cursors for invalid and valid drops (instead of the circle with slash indicating invalid target, i want a red minus) and (instead of the little plus sign with little box indicating a valid target, i want just a big green plus sign) add a red insert line to indicate where the node would be dropped within a tree also drag and drop the text of a node from the tree to a textbox add a "folder" image next to parent nodes and a "document" image next to children nodes

I've written a pretty good browser in vb.net (it's in the "Share your Project" forum). I now want to give users and other developers the ability to extend/add buttons & functions to it.

I was planning on these being small snippets of code which my application has the ability to compile.)
View 5 RepliesI want to be able to hold CTRL down to select multiple text entries and drag them all to certain text boxes. Or even one at a time, but once I try dragging another word into the box it replace the first one. Is there any way to just have it add to the text box rather than replace it?

I've seen the code on this site to setup a drag-and-drop between 2 listboxes (and that works perfectly for me), but I have a need to be able to move items between up to 12 listboxes. For example, I move an item from listbox1 to listbox2; at some point in the future, I need to be able to move that same item from listbox2 to listbox3, then at another point in time from listbox3 back to listbox1, etc. When I make these moves, I need the item to be removed from its previous location. I've attempted to modify the 2-listbox code to include, on my test form, a third listbox, but that code copies to the third listbox, and when I attempt to move the item from the third listbox to the second, it, too, only copies and does not remove the item from listbox3.

View 6 RepliesI am trying to make a nifty little drag control.I have a custom list that I start the drag from.As i enter a main panel for my program, I create a control that is made from the source control.I then draw the control to a bitmap, create a nativewindow that is semitrasparent and draw the bitmap to it...giving the transparent file drag illusion.It all works great if I drag the control just under the cursor. If I draw it on the cursor, it changes focus to the nativewindow.I would like to know how to either be able to keep the focus on the panel so that the dragleave is not fired until the panel is left or interupt the underlying commands so that I can pass the info to the panel.
