I have a ListBox control, that contains a few items that display attachments (files or directories). I have successfully allowed users to drag and drop items from their desktop to the ListBox , but I have not been able to allow the user to drag and drop items from the ListBox to their desktop. Is this possible?

Is it possible to (without a mile of code) Drag and drop files from a datagrid to the desktop or open folder?
I have tried this:
Dim sFile As String = "D: est.pdf"
C1Grid_Documents.DoDragDrop(New DataObject(DataFormats.FileDrop, sFile), DragDropEffects.Copy)
But no file is created.
Is it possible to drag an drop a desktop shortcut to the form and then launch the program from there ? Is so how would this be done ?
View 39 RepliesI found this thread[url]...
and I have encountered the exact same problem, that the desktop shortcut icon created by the Setup program does not work when dragging and dropping a file (in this case an Access-database) onto it,
while a shortcut manually created works just fine.
I do not understand the answer in the above thread. But, anyway I would like to find a way to solve the problem directly, preferably through the Setup program itself.
This is a little diffrent from your standard drag and drop, but I am trying to find out a way to support drag and drop, from a list control, which is displaying a list of files, held as "blobs" in a SQL database (compressed data in my own format). When the form is opened, I obtain a list of all the file names within that given table in the database, and display it to the user in the list view control. The user then has the option of dragging that ListItem from the ListView on to the dektop (or other directory location). Upon doing so, I need to be able to read the data from SQL, decompress the data (in my own format) and then save it as a file at the dropped location.
My main problem is detecting when the ListItem is dropped outside of my application, as I want to use this dropping event to trigger the code in to obtaining a copy of that file from the database, and save it in to the "dropped" directory, where ever that may be.
So Im mainly looking in to how I can "see" the final location where the item is dropped, and how I can start off the drag and drop operation in the first place with no initial data (since I have not obtained the file at the start of the operation). Getting the file at the start of the drag and drop operation intoduces "lag" while the application makes the trip to the SQL database (via web service) and obtains the data, so I need to carry out that trip to the database, at the end, while still allowing "Windows" to act as if I am dragging and dropping a file...
I did consider multi-theading, and downloaind the file from the database while the drag and drop operation is in progress, but then it becomes a race between the data being obtained from the database, and the user dropping the file.
Im using VS2005, SQL 2005 where the file is stored as a blog. SQL is on another PC running a web service which I interact with, to allow my application to talk to the database over both a LAN and WiFi via the internet. Compression and de-compression is handed at the client side application (for the file itself, in order to reduce the footprint created by the internet traffic) , where the user interface is displayed.
I'm having trouble with my panels. I taught myself VB (and the other languages I know) so I don't know all the terminology, so bear with me. But I'm making an application, and in this application I have a set of radio buttons, and because I only wanted one to be checked at a time, I put them in a panel. The problem is, I want to add more stuff to the application (form?) and anytime I add something that is in the area of a Panel, it becomes part of that Panel.
This is all fine and good when you are trying to drag and drop something right into the panel, it makes it really easy. But when I'm trying to drag and drop something else in that area where the panel just happens to be, I don't want it to be in that panel. So how can I make it so the panel stops parenting my other items on the page? I hope that makes since.
I was just wondering, if I have a list view control, with 2 columns, and insert items to those columns, ex:

That is my question I hope you can give me an answer if this can be achieved trough the listview control from vb.net or other control that you know of. If you post an example in C#, maybe I can create al DLL and put it as a control in my vb.net tools, but I just want to know if this can be done.

I've been successfully dragging one item at a time over from a listbox to a treeview, but now that I'm trying to adapt it to drag/drop multiple items, I've run into a problem.I'm getting an index out of range exception in the loop where I'm trying to gather the listbox items into a string array. Any index greater than 0 throws the exception, even though I have set the length to equal the number of selected items in the listbox. I've double-checked that this is the case many times. Watching the selecteditems.count value, I can see that it is equal to the number of items I have selected, naturally, but the exception is still thrown on this line:
sel(i) = AddonsList.SelectedItems.Item(i)
Here is the relevant drag/drop

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
