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

line4
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 am using Excel 2007, VS2008 Pro.I am building a VSTO Add-in that requires "drag and drop from Excel cells to a drag-enabled task pane".So far I notice that I can only drag and drop within the cells themselves. It does not allow me to drop into the task Pane or drag past the sheet limits.(http:)[url]...
Note: The task pane has drag drop enabled, I ahve already tested I can drag/drop from task pane to excel but I need to do this the other way around?
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 populate a listbox with locations search results, I then have 6 panels below the listbox each with a combobox containing all available locations. I want to allow the user to click on one search result in the listbox and drag to one of the 6 panels and set the combobox.selectedvalue = listbox.selectedvalue.
i have researched the drag and drop and have yet to figure out how to accomplish this. I think i could do it using some key down events etc. ?
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 have looked through the internet but I am having difficulty sorting through all the information available (I see a lot of information for Visual Basic 5 and 6, and those codes don't work for me in visual studio 2008). I can email anyone my code I have so far.

I 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?
And if possible, place a "-" between each entry?
This is the pop-up form with the listbox that contains the words to drag:
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown

I am getting close, but I am having trouble getting the data to drop. I did some testing and I can drop a string, but I am not able to get the string data from my listbox. I just get a datarowview. I see the string inside the "itemarray", but cannot get to it.

I have this sub:

Also if I declare the nodebtn as a global variable, I do not face this problem, the button is dragable. However when I click to add new buttons, no new button is generated, instead a button is generated with the count on it.
I have this app that gets the files/subdirectories from a selected one (it stores the files with their icon in a listview), I was wondering how could I drag a selected file from the listview into another directory (outside of the form), let's say the desktop.
How can I do this? I have only found examples of how to do drag/drop within the same form.
