Disable Drag&Drop Of Files In Richtextbox In .NET?

Mar 17, 2010

I use a .NET richtextbox and I want to have the EnableAutoDragDrop property set to True. This allows user to drag&drop text, rtf and images around etc. However, I need to process files dropped into the richtextbox myself - I do not want them to be embedded as OLE objects when they are dropped.

How can I overcome this? Is there any way to delete embedded files from richtextbox?

(I've found API DragAcceptFiles which doesn't work for some reason.)

Can A Full File Manager Be Built To Drag And Drop Files

Feb 17, 2011

I am working on a vb forms application in VS2008.What I am looking to do is have 3 file managers on the form.The top is the source where files can be copied to the 2 other file managers.What I have been looking for is an example of the file explorer so I can modify it.So far I have been unsuccessful in finding a good example so I am here to ask the experts.So the gist is the first file explorer will allow a user to connect to thier local hard drive.The other two file explorers would allow the user to connect to two different servers through entering the path they want to view those file trees.After that the user could click on the file they want to copy and then hit a button for example and the file would be copied from the local to the two other areas.Would it be easier to just use text boxes with a confirmation that the files are being copied?Or can a full file manager be built to drag and drop files?

Drag/Drop Within A Tree And Drag/drop From Tree To Textbox

Oct 20, 2010

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.

Public Class Form1
Private MouseIsDown As Boolean = False

Can't Drag And Drop Right

Jun 23, 2009

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
ListBox1.DoDragDrop(ListBox1.SelectedItem, DragDropEffects.Copy)

VB Drag And Drop From LB To DGV

Sep 9, 2009

I am writing a small program that has two list box's which are populated from my sql database. I want to drag an item from LB1 to column1 in a datagridview and drag an item from LB2 to column2 in the same datagridview.

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.

Here is my dodragdrop:

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.

Drag And Drop Across The Screen

Jan 23, 2010

I am very new to Visual Basic, but I am trying to build a simple program, and how to create a drag and drop that works, but I can't seem to figure out how to change the display as I drag across the screen. Basically, right now I have a circle with a line through it that goes across my screen as I drag and what I would like is for it to be the text that I am dragging that drags across the screen, just like a file on my desktop would do when I grab it and try to drag it somewhere else on the desktop. I have put my code in below, how to get rid of the circle with the line through it, and replace it with the actually text that I am trying to drag. I am using Visual Basic 2010

Public Class frmDragDrop
Private Sub labelMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lbdragfrom.MouseDown
lbdragfrom.DoDragDrop(lbdragfrom.Text, DragDropEffects.Copy)

Drag And Drop Between More Than 2 Listboxes

Jan 8, 2010

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.

Apr 17, 2010

I 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 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.
