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.)

i have to forms, one with a RTB on it, the other with a treeview on it.I want to be able to drag a image from the treeview over to my rich text box.Basicly like a clip art window.The treeview nodes have a short description of the image (e.g Dog) then a picture of a dog next to it. I want then to be able to drag that into my rich text box, and the picture of the dog to appear.Is there a easy way to do this?

I know that there is usually a DoDragDrop method that starts a drag and drop operation. And that there are events (such as DragEnter, DragOver, DragDrop, DragLeave) that can be handled on the target side.
Are there any events on the source of the dragdrop that will tell me whether the dragdrop operation was completed, or possibly cancelled?

I am new to vb.net and development in general. The basics are I have a control that accepts dragdrop, I use this control to drag files onto - based upon the text contained in a combobox the directory path is built in the dragdrop event, and I initiate System.IO.File.Copy. I then refresh my listview, which is working well and is listing files based upon the content of a directory. Here is my code for the dragenter and dragdrop subs
Private Sub pnlDataDrop_DragEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles pnlDataDrop.DragEnter
If e.Data.GetDataPresent(DataFormats.FileDrop) Then
e.Effect = DragDropEffects.Copy
[Code] .....
I have added some break points so that I can see the values for targetpath and myfiles(), and all looks ok. The app is in its very early stages, so I am only testing in the development environment at the moment. So you know, the targetpath is a UNC: \myservermydirectory.

In my vb.net application I am using richtext boxes with readonly property set to True
but still its font size can be changed using mouse wheel and default windows keyboard shortcut for fontsize change (ctrl+shift+ >/<). So how do I disable richtext box font-size change?

Finishing off my control, but I now found a nasty problem. When the user holds the 'Ctrl' key and scrolls the mouse scrollwheel, the control is scaled. I do not want that, since it would make the Font size fail.
I previously made it reset the scale on Control up, but that is just not a very elegant way:
Me.ZoomFactor = 1 I do not want the text scaled at any time, not even while the user is scrolling and it resets afterwards. I got to overriding the 'ProcessCmdKey' but no idea how to catch a scroll or zoom event.
Any way of disabling the RichTextBox scaling (or zooming) so it does not even occur? I have a control that inherits from the RichTextBox.

I'm writing an vb.net application so that the user can type text to be added to a website. I'm using a richtextbox and I've added the facility to hyperlink selected text. This all works, but when the mouse cursor moves over a hyperlink it changes to a hand; how do I stop it doing that? It's confusing for the user as it looks like clicking the link will do something and it makes it awkward to correct spelling within the text of the hyperlink.

When I select text with a mouse in dense text like an XML file the selection automatically extends to what it thinks is a white space (or?). How do I turn off this "word selection" and just select the characters the cursor passes over?VS2010 Beta, VB.Net

I have in my form 2 RichTextBox , one Listbox , one OpenFileDialog and one Button . In those 2 RichTextBox I would like to load two (*.RTF) FILES .
Application Steps :
1- When I click the button , an OpenFileDialog open .
2- I choose those two files (*.RTF) and when I press the OK in OpenFileDialog, the path of those two files are written in the ListBox as Items.
3- After getting the path of those two files , I would like to load them into those two richtextboxs .
The problem is that I don't want to specify the richtextboxs names in order to load the files . What am I saying ? I.E : I don't want to use that code : "RichTextBox1.Loadfile(Listbox1.items.item)" When I debug my application : everything goes well , only when the listbox items are loaded in the richtextboxs control I get only one file loaded on those two richtextboxs. Right Now I have written these codes :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
OpenFileDialog1.Filter = "RTF Files (*.rtf) |*.rtf"

I'm developing a command line application in Visual Basic .Net 2005 for converting RTF files into TXT. The application works perfect except for one thing. The files saved with MS Word containing some textbox make trouble. I'll explain it better with an example
1 - I open MS Word, I create a new document.
2 - I insert a texbox and i write some words inside.
3 - I save the file as RTF.
4 - I use my command line application for converting the RTF into TXT. The text inside the textbox doesn't appear anywhere.
The thing is that if I open the RTF file with wordpad it shows the text. It's not in a text box, but it shows it.The problem is that this application will read files uploaded by users automatically so I can't just leave it like this, I have to take into account that there is the possibility that some user will save an RTF file with a textbox inside so I need it to be able to get the contents of the textbox the same way wordpad does.
Here is the code
Try
Dim args(2) As String
args = System.Environment.GetCommandLineArgs
Dim c As New System.Windows.Forms.RichTextBox

I suspect that the LoadFile method cannot read the TextBoxes in my RTF file, or maybe i'm missing something. Attached is the file i'm working on.

I am trying to drag and drop items from a listbox into a richtextbox? I can not get the .DragDrop event to fire? I have copied and past the code from [URL]
I can get the .DragEnter event to fire. The mousedown event fires the drag and drop, is there something for mouseup?

I am dragging and dropping values from a listview to a datagridview cell.In the datagridview I have AllowUserToAddRows = True because I want them to drag in as many items as they need.
The problem is that when I drag an item into the new row a newer row is not created below it as it would if I had typed something int he cell and left.
I tried to add a new row on the CellValueChanged event but that inserts a row above the row that I just dragged to.
Anyone know how to trigger that event after a drag and drop?

I have a FlowPanelLayout that can contain several UserControls called DataGridViewFilterSortElement. These controls look kind of like buttons, but different. I want the user to be able to click one of the DataGridViewFilterSortElement controls and drag it to another position (index) in the FlowLayoutPanel. Is there a way to see the control physically moving as the user drags it to another position? In other words, is there a way to take a "snap shot" of the control that is being dragged (instead of a shadowed box) which would show the actual control moving as the cursor moves?
Also, as the control is being dragged I'd like to have the other controls position to shift automatically instead of waiting for the user to drop the drag to see the shifts. For example, let's say the FlowPanelLayout contains 3 controls and the user wants to drag the first control to the third controls position. So the user clicks and holds the first DataGridViewFilterSortElement, then drags over the second control, which causes the second control to shift to position 1 of 3, then the user drags over the third control, which causes the third control to shift to position 2 of 3, then the user drops the control in position 3.
Here is a short little video that shows what I want to do: Video Example
Private Sub lblDescription_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown, lblDescription.MouseDown
' if the user left clicks and holds the element begin a DragDrop action
If e.Button = Windows.Forms.MouseButtons.Left Then
Me.DoDragDrop(Me, DragDropEffects.Move)
End If
End Sub

I have a treeview dragdrop event written in VS2003. It works perfectly fine when the application is running on desktop, until we move the application to Citrix. So, users are now running it off from Citrix, the DragDrop event doesn't work anymore. It doesn't even have the effects of allowing dropping.

Below is a practical example of how this would be useful:A practical example would be an FTP client where a user dragdrops files to be uploaded and would naturally want to dragdrop remote files to their local folders with the intention of triggering a download of that file to the folder they dragged the listview item to.

I trying to do a drag drop from a listview in one form to another instance of the same form (same application running twice).I have it working with single items selections, but I want to make it work with multiple selections. 289508(VS.71).aspxThis works if I drag/drop onto itself (the same form), which I don't want, but I need it to work across instances.During debugging it seems the code DragDrop code just quits at the line during the drop:Dim myItems() As ListViewItem = e.Data.GetData("System.Windows.Forms.ListViewItem()")Any ideas what is wrong or how to drag/drop multiple items in a listview between apps?
here's my code:
Private Sub ListView1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles ListView1.DragDrop
