VS 2008 Drag Drop Multiple - ListBox To TreeView?
Feb 13, 2010
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

Trying to drag/drop an item from one listbox to another on a windows form.Listbox1 is bound to a table and the data is populating correctly.Listbox2 is empty and has allowdrop set to TRUE. The goal is to drag items from LB1 to LB2.Problem is when I click on the item in LB1 it will not allow me to drag the item to the other box. As soon as I click on the item in LB1 the mouse pointer turns to a circle with a line through it.

I am planning on having 12 - 14 listviews on my form.Do I have to copy the above code and name each source and destination listview for all combinations that I want to drag to and from? Or, is there code that will 'read' the source listview1 name when clicking an item from the list and 'read' the listview2 name when the cursor is on the listview I am dropping the item into.Been searching but probably not using correct terms.

I have a simple TreeView with HotTracking Property set to True. It works when I move the mouse over an item. But it doesn't work when I use Drag&Drop and Drag something over a TreeView Item. Is there a way to use the HotTracking with DragDrop? Or any workarounds?

I am building a 'shape editor' which looks very similar to the Visual Studio form designer. I have a Toolbox control that holds a few 'Shapes' (such as RectangleShape, EllipseShape, TriangleShape, etc) which the user should be able to drag to the design view ("Canvas") in any MDI form. The Toolbox control is just a TreeView except that I add ToolboxItems to it (which are inherited TreeNodes). This dragging however does not seem to work...

I'm able to drag and drop a node. The treeview is loaded with files and folders on the HD. The tag of the node has the path to the file/folder. [code] I only want to be able to drag a node into a folder and not into a file, as it does with this code.

I'm having trouble figuring out how to do this. I'm using VS2010, and am writing an app that must allow a user to drag an attachment from an Outlook e-mail onto a listbox and have the listbox populated with the contents of the file. It would just be a text file containing filenames, one per line.

For some reason when I try binding the listbox to a datasource I put in (it contains a table of words to be used in the listbox), it shows me a + sign like it will allow my to drop text in but then it doesn't insert anything. Does this code not work for databound related things?
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
ListBox1.DoDragDrop(ListBox1.SelectedItem, DragDropEffects.Copy)

Is it possible to modify this section of code to select multiple instances of pictureboxes, so that I can drag them all together. At the moment I have to do one at a time, and when there's more than half a dozen, its a bit tedious. I've added the Control key to distinguish it from single drag'n'Drop, but.

e.Button = MouseButtons.Left And My.Computer.Keyboard.CtrlKeyDown Then

I found this code but can't use it as its VB6 and I need VB 2008. I tried changing it but can't seem to get anywhere.
Code:
Private Sub List1_OLEDragDrop(Data As DataObject, Effect As Long, Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim vFile As Variant
If Data.GetFormat(vbCFFiles) Then
For Each vFile In Data.Files
List1.AddItem vFile
Next vFile

Public Property AddImageCommand As ICommand = New Adjuster.DelegateCommand(AddressOf addImage)

I am trying to figure out a way to include the listview's tag field when dragging one listview's subitems into another listview. I am hoping someone here has experience with this. My Listview drag code is below - the two listviews that I am dragging subitems into or from are LV1 and LV3. Also, this is being done in Visual Basic 2008 and the project is a windows application.

I am trying to add multiple files to FTP server by dragging and dropping and I am able to do that using try catch block and if we give the ftp settings correctly it takes 1 sec to upload them but when we give wrong details it hangs up and dosen't give me any error message though If I give an exceptional message.
Now I am getting error message as well as success message for every file I add.I do not want that to be happen.where should I give messages for success and failure so that it should take few seconds for uploading and if not should give me a message immediately.
Here is my code:

I've looked everywhere on the internet for multiple items drag&drop between listboxes and found only examples showing single item drag. I know how to make a single item dragdrop operation between two listboxes using MouseDown, DoDragDrop, DragEnter, DragDrop Now what I'm looking forward to learn is the ability of dragging more than one item from one listbox and dropping them in another listbox
