I had a user ask me today if I could make it so they could simply drag and drop text from other programs into the app I've written. I found an old (2002 & 2003) article on drag and drop, but I'm sure things have been made better since then.
Anyone doing this today can point me in the right direction? Is this much of a pain to enable?
I am currently working on a drag and drop project and I was wondering if there is a way to drag picturebox1 and drop it in picturebox2; that will snap to a specific location in the picturebox2?

Can it be drap and drop item to other form control??How to write the event when mouse up at the other form control?
I am dragging a control over a different control as part of a drag/drop operation. AllowDrop is set for both the dragged control and the drop target. There is a DragDrop handler for the drop target, but when I drop on the target, the handler is never called, and nothing happens. I expect that I am overlooking something simple, but, as might be expected, I can't see it.
When I drag onto a different type of control, it is working correctly, and dragging to the control in question was once working correctly, but not anymore. I did make a bunch of changes, but the fundamental issue is that the dragdrop event is never raised for the control that is the drop target.
I have a picturebox that has a semi-complex image on it and also has a series of other pictureboxes, most of which are set to not visible. The way the program works, the user can click and drag a couple different items on the parent picturebox. The things they can drag are not actual controls, but parts of the image itself. That is all working fine. While testing, I had all of the subordinate pictureboxes (there are a variable number of them) visible showing a black background. I have now improved their implementation, so I changed the display so that only the subordinate pictureboxes that actually have something in them are visible. For all the others, they have .Visible = False.
The problem is that when I click and drag on one of the items in the parent picturebox, all the invisible pictureboxes become visible. They have no image in them, so they take on the color of the backgroud behind the parent picturebox. This is undesirable. I want the invisible pictureboxes to remain invisible during the drag and drop action. The one solution that seems promising is to set the image of all those pictureboxes to some transparent image such that, though they are visible, they will not appear as anything. A bit of testing shows that this technique would work.
I have finally got the drag and drop to work on my form, so the user can drop files on it. I have used the msdn example so i can get the whole filename (path + filename). But how do i get only the filename? (lol.zip) And maybe the path where it is?

Is there any way of detecting the position where the Mouse Button is released during a Drag & Drop operation. I need to know whether the intended Drop position was not reached when the mouse button is released.
View 8 RepliesI 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...

View 3 RepliesI am trying to make a renaming program, which I have done, but wanted to add drag and drop support. Firstly, when I drag and drop the files into a listbox they appear to be going in and are ordered randomly. I want them to go into the order they're dragged in. Secondly, instead of having the entire path such as:
D:TVThe Big Bang Theory SeasonSeason 1The Big Bang Theory S01E01 - Pilot
I want just "The Big Bang Theory S01E01 - Pilot" to go into the listbox.
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.

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.
