Drag An Item From Treeview & Drop Picturebox In Windows Form?
Jun 11, 2012
I am trying to drag an item from treeview node and number of movable picturebox should be created on windows form as we drag.But in my programme, we can drag a parent node also, and only one picturebox is created.
Public Class Form1
Dim pic As New PictureBox
Public drag As Boolean = False
implement an algorithm to drag-and-drop a picturebox in my form. For example, what Windows does when i want to drag and drop files (or folders) on my desktop.
I have been developing an app in VB.NET which requires a control object (for example, a ListViewItem) to be dragged out of the form, and to a user-specified location (for example, on the desktop, or in a folder). However, The file that is intended to be 'copied', as the 'ListViewItem' represents, does not yet exist. It needs to be downloaded and then placed in the user specified location. Am I able to get the path/location of the destination drop? I would then proceed to download the file, and then place it where the use specified.
I have looked at other questions regarding a similar issue, which details the dragging operation outside the form, its just there doesn't appear to be a way to determine where that short cut went or how to flag the destination location. Essentially, I am thinking that it may require some sort of 'dynamic link' or 'virtual file' as I've seen mentioned elsewhere. Then, after the drop operation, somehow accessing this 'link' from my application, proceed to download the file and place it in the final drop destination.
Using Visual Studio 2010 I am trying to using windows form drag and drop by datasource .the grid generate automatically and with navigation bar with few controls like add, save , delete.But its not work on main table , meanS When I want to add new , it show saved but its not saved in actual datatable.
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'Agents_DataSet.trans' table. You can move, or remove it, as needed. Me.TransTableAdapter.Fill(Me.Agents_DataSet.trans)
Google Chrome has a handy feature where I can click a download link and drag it into a Windows Explorer window, and then drop. After dropping, Chrome then downloads the file and it appears where I dropped it.
I would like to be able to drop from Google Chrome into my application, but it seems it isn't so simple. I have a DataGridView called gridFiles, and the following code:
Private Sub gridFiles_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles gridFiles.DragDrop If e.Data.GetDataPresent(DataFormats.FileDrop) Then
[Code].....
EDIT: So it seems that with regular URLs, I do get the proper dragged-in UniformResourceLocator format. The behavior I am seeing occurs with the download links in Gmail. It probably happens elsewhere, but I am not sure. When a gmail attachment is dragged from Gmail into my application, I get a FileDrop.
Doing some more digging, it seems that Gmail is using the download_url attribute of the anchor tag. I have never heard of this before. Perhaps this is just an extra property they have added?
In any case, since my application will primarily be used with e-mail attachments, I need a way for the phantom FileDrop to work, as stated above. I am unable to use Spy++. It doesn't seem to show any messages when drops occur.
Edit #2: Here is more information on how Gmail utilizes drag/drop for files: [URL]
I am implementing Drag & Drop in windows application. I have Main Form (Has a toolbar with Search, Open, Print etc) - MdiContainer On Search - Open a child - Search form. Drag and Drop a file to a Grid on this search form. In DragDrop event of the Grid - Call a Modal form. I am having trouble here.
i have to treeviews both ownerdrawall on 2 forms. the main from had the wndproc overriten.My question is why would the line in red make the the program jump to the wndproc on the other form not to return again and compleet the routine? [code]
eir sequence recommended for a effective drag and drop control of the nodes in the same treeview control.I'm using windows XP with vs 2005 and code written in vb.
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'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
I have a simple textfile which I want to drag-drop into the treeview. After the drop read the textfile (line by line) and create the nodes. There are no subnodes (what-so-ever). File looks like this:
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.
ListView Drag&Drop allow to Drag&Drop between form??
Public Class frmModule Private Sub ListView1_ItemDrag(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag[code]....
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'm trying to enable drag'n drop with VB 2008:Source is a bitmap in a picturebox, destination is MS Word.When I use Wordpad instead of Word, every thing works quite well. But not with Word.
i know how to display an image in a picturebox by drag drop. but cant find anything on the net about dropping an image to a textbox then having the textbox display its location
reolved if any one else searches for it. Dim Files() As String = CType(e.Data.GetData(DataFormats.FileDrop), String()) Dim fileDetail As New System.IO.FileInfo(Files(0)) txtFilePath.Text = fileDetail.FullName
I am once more stuck:There are 2 PictureBoxes on my Form. They get the image from the Application's StartUpPath, "1.jpg" for PictureBox1 and "2.jpg" for PictureBox2. All the dragging and dropping works fine. What I still need is a bit of code change that will allow me to rename the original files:
Here is my code on A Drag and Drop from button to PictureBox:
vb Public Sub New() InitializeComponent() Dim img As Image = Image.FromFile("C:file.png") Me.btnImage.Image = img Me.picBox.AllowDrop = True AddHandler btnImage.MouseDown, AddressOf btnImage_MouseDown
[Code]...
And what i want to do is to make the picturebox 500x500.then make several buttons representing different images. and then make it possible to drag and drop several images in the same imagebox and move them around. and hopefully i can make a button for saving the coordinates of the images and the image paths into a text file.
I have two (Telerik) TreeView controls, let's call them tvSource and tvDest. I want to drag/drop items from tvSource to tvDest. I have this somewhat working, but am experiencing two problems:
1) What it now does is moving the item. Instead I want them to be copied (from tvSource to tvDest), leaving the item in tvSource.
2) To allow items to be dragged from the tvSource control I have to enable DragDrop. With this enabled the user can drag/drop inside the tvSource control, which is not what I want. The items may only be dragged (copied) to an other control (tvDest).
Below is my code so far:
Private blnMouseIsDown As Boolean = False Private Sub tvSource_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles tvSource.MouseDown
I was just wondering if it was possible to create a code so that when you drag the favicon on another textbox that textbox's text could be the URL of your navigation textbox (aka the url you are on right now) Like a kind of bookmarks toolbar like firefox.
I've an app wich alows the user to drag drop images into a picturebox. It works on xp, it doesn't works on vista and seven since the UAC could cause the problem. I've tried running it as administrator and still it doesn't work.
The following website appears to show you you might do Drag/Drop that works like explorer does but I don't know what the code would be in VB, what exactly i'd need or anything else. It's a quite large code base just to make it so you get the same effect as explorer even though it seems to be API's or .dll's that should handle most of the work.
If the API's & .dll's available for this don't handle most of it I don't see why not because well if your meant to get the same effect why is it going to be handled mostly by code? I would think it would be as easy as passing an image or file/folder as string & then there the image is & possibly the functions you want to be allowed or text to be displayed for the drag action & then a little more to determine where your trying to drag to so what the text should be changing to.
Anyways heres the website which has a lot of the information/code in non-vb language, even when translated to VB using online tools I couldn't figure out what did what or what pieces I needed to get a basic drag action to work that has said visual information like explorer does.[URL]..
im working on a drag and drop project, currently im able to drag and drop desktop shortcuts and launch them by click on them.Now im wondering how would i be able to drag and drop folders (My Pictures, My Documents) etc. im using multiple pictureboxes , only picturebox 1 code is shown here.[code]
