I'm doing drag and drop from a list view. In my starting list view's ItemDrag event handler, I say (amomgst other things):
data.SetFileDropList(coll) data.SetText(CurrentFolder, TextDataFormat.Text) sender.DoDragDrop(data, DragDropEffects.Copy Or DragDropEffects.Move)
CurrentFolder being a string that holds the name of the folder represented by the list view. In the target control's DragDrop event handler, CType(e.Data, DataObject).GetText evaluates to what CurrentFolder was when ItemDrag was executed.But: e.Data.GetDataPresent(TextDataFormat.Text) always evaluates to FALSE.If I replace "TextDataFormat.Text" by "DataFormats.Text" (in both places) the result is the same. I am asking this although my code does what I want, because I feel that I should not call CType(e.Data, DataObject).GetText before I have established that TextData is actually present. So how do I properly check for the presence of the text data.
I have a pop up form that contains a listbox. Right now I am telling it exactly which text boxes I want to be able to drag and drop to, but I was just told to have it drag and drop to every text box on the main form.The main form with the text boxes has a bunch of tabs on it that hold each section. Each section has text boxes, so how would I code it so they are all capable of allowing drag/drop without specifying each one separately?
This is the code from my pop up form:
vb Private Sub txtDropIn_DragDrop(ByVal sender As Object, _ ByVal e As System.Windows.Forms.DragEventArgs) Dim DropInTextbox As TextBox = CType(sender, TextBox) Dim TextToDrop As String = CStr(e.Data.GetData(GetType(String))) 'get rid of leading " - " if there isn't 'anything in the textbox If String.IsNullOrEmpty(MainWin.TextBox1.Text) Then TextToDrop = TextToDrop.TrimStart(CChar(" -
I insert a text box into form1. I move the mouse pointer on top of the text box. I press down on the left mouse button and begin to drag the text box. The problem is when I let go of the mouse button the text box is not dropped. it remain floating around. My only way out of this is to press the escape key which places the text bnox bak to its original location. Thinking that it might be my mouse I tested it in Power point and everything works correctly.
I'm running Windows 7 x 64 and the latest version of VS 2008.I have spent forever trying to get the following VB6 code snippet to work in a VB 2008 Windows Forms application. The VB6 application works like a charm, even on Win 7 x64.Here is the relevant (I hope) VB6 code. It allows me to select text in IE8's browser window and then drag and drop it onto a TextBox called txtLink in a very simple VB6 application.
Code: Private Sub txtLink_OLEDragDrop(Data As DataObject, Effect As Long, Button As Integer, Shift As Integer, X As Single, Y As Single)
I have AutoDragDrop enabled in my textbox. It drags the .jpg file into my program successfully. When I save it only saves the text not the .jpg file. I do realize that when I save the file I need to have the .jpg saved also and I am not sure how to accomplish this. I have checked multiple forums and googled of course. No luck as of yet.
I need to drag and drop to textbox from tree view. Here while drag and drop to text box i need to add the dragged text to anywhere in the text box which we have already dragged some nodes here.
For example.in treeview i have "node1" and "node2"now i am going to add "node2" to textbox and in front of "node2" i need to add "node1" and then at the end of "node2" again i need to drop "node1" like that.
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.
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.

Is it possible to reorder the elements of a drop down list (combobox) via drag and drop?For example, when the list is dropped down, I want the user to be able to drag the items up or down to reorder them. I tried this (and some google searching) but I'm wondering if its just not possible:
Private Sub cmbClassLists_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles cmbClassLists.MouseDown If cmbClassLists.DroppedDown And Not cmbClassLists.SelectedIndex = -1 Then
I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple
RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")
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)
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.
How to implement Drag and Drop multiple objects in the form in Visual Basic. The drag-able object will be provided within the same form but in a different panel. I must be able to delete the object also.
I am trying to generate buttons and allow the user to drag and drop them.
I have this sub:
Sub Form1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseClick Dim nodebtn As New Button
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.
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) End Sub [Code] .....
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.
I'm a relative novice at coding in visual basic 2008 and am trying to implement dragging and dropping filenames from windows explorer into a listbox within my VB app. My customer wants to do this as opposed to selecting filenames from a directory browsing window.
I'm creating an application in which the form contains one datagridview and 20 pictureboxes.When the DGV is populated, the user will drag a row from DGV and drop in any one of the pictureboxes.The picturebox should able evaluate a column value(say column 1) from the dropping row and according to that it should change its picture.
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 it...giving 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.
OK, so I want to read in the file as whatever someone drags and drops on the .exe file. Once I get that file to be used as the file in the program, I'm fine, I know what I'm doing, but I'm having no luck getting that part done.So far I have this that I found:
Code: Dim s As String = Command$() Console.WriteLine(s)
