I want to remove a group (include all items in this group) in ListView, but unsuccessful, the code is below, why?
ListView1.Groups("GroupName").Items.Clear()
ListView1.Groups.Remove(ListView1.Groups("GroupName"))
I have a WinForms group box that needs to be sized programmatically. Everything else is working well but I am having trouble with the below line of code because as the form is re-sized larger the group box grows over the buttons that are underneath. I am looking for a way in code so that the group box grows with the form, but no so large that it grows over the button underneath it.

I am trying to load bulk images and trying to put them as a slideshow and it's working fine. Now I would like to have some effects like flip out,ease out effect and fade effect on those images when changing them without using any user control as I would like to do with the existing picturebox.Is it possible to do so?
If so can anyone point me to some resources.As I have done googling and found some useful links and I am placing here that might helpful to someone.And all these have use seperate usercontrols to do, and I am not looking into that.[URL]..

View 3 RepliesIn main thread I create panel(s) (based on some configuration), and then in the next step based on the file type (like video, ppt, image...) I create appropriate controls (dynamically) to show on the forms.
The creation of the control will be done in separate threads (for each file). After creating the control, it throws an error when I try to add that control to the panel (which was created in the main thread), something like cross thread violation, control was accessed from one thread other that it was created.
Can some one please help me in this regard? In this scenario, everything - creating the panels and controls - will be dynamic. Nothing will be static.I tried some of the articles found here on StackOverflow (like, control.BeginInvoke() .. etc), but wasn't able to solve my problem.
I've created a news ticker control, which reads from RSS feeds and scrolls the text Horizontally. The plan is to have 3 of these on my Windows form, which will each display their own information.
The control is created as a label, which is populated with the text, and then scrolls right to left using a timer, once the label gets to the end of the text, and disappears of the left side, the rss is re-read, and then the cycle resumes. The problem is that with multiple copies of this controls on my form, once one gets to the end of it's run, all three freeze while the rss is reread, rather than just the control that needs to do it.
Is there a way to run each of these controls independently (threading?)? Or is there a glitch in my code causing this? (below - some elements not included, but it should be fairly obvious what is happening!)

I have a form with a datarepeater that contains various controls (i.e. datetimepickers, text boxes, combobox) that are populated via a binding source. I also have other controls on the form that are not part of the data repeater. I would like to force validating all controls after the data is populated. I have successfully forced validating the non-datarepeater controls using Me.ValidateChildren() at the end of my load event. However, it does not fire the validating events for the controls within the data repeater. I have unsuccessfully tried many different attempts to set and move focus within the datarepeater controls trying to get the validating events kicked off. I am not sure where would be the best place (e.g. in drawItem? in ItemCloned?) to place the code and what it should be exactly.
Here was my latest attempt:
Private Sub DataRepeater1_DrawItem(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs) _
Handles DataRepeater1.DrawItem
For i = 0 To e.DataRepeaterItem.Controls.Count - 1
e.DataRepeaterItem.Controls.Item(i).Focus()
e.DataRepeaterItem.Controls.Item(0).Focus()
Next
I successfully handled the validating events in the data repeater caused by user input errors. However, I have the unusual situation that the data coming into my form is already bad for some of the controls. The purpose of the form is to validate the data coming in to it and from user-input. I am newbie with vb.net.

I'm writing and application that creates a home folder for a given user. I can set the permissions fine, but on some of the folders I need to remove a specific group/user, "Everyone" would be an example for one of the folders. I can make it so that they are denied from all the permissions on the folder, but I can't actually get the group/user remove.

I'm having problems removing dynamic controls.
Here is what I'm using:
CODE:
The first sub is for adding the (custom)control, the second sub is for removing the control.
The custom control is a picturebox with a checkbox in the upper-left hand corner, no big deal.
The problem is that when I click the delete command, it only deletes one ckPicture at a time, and allways the last one in the list. I'm also assuming it's doing the same thing in the list(of images). What should I do differently so that it will remove all controls that are checked?
I forgot to add the variables in my namespace.

This is my first post here as I am in the process of writing my first vb program. I just recently learned VBA and prior to that I had no programming experience. I decided that my first attempt with VB would be to convert a program that I previously wrote in VBA. It runs in an excel workbook but it doesn't actually use any excel functions so I figured it would be acceptable to convert. I am having an issue with removing controls on a userform. A commandbutton adds a line of about 6 controls. The user can add as many lines as they need to input their data. One of the 6 controls is a delete button that deletes the line of controls next to it. I have created a collection named Cashflows that holds each line of controls and each line of controls is named with a number that indexes the name to the line that it appears on in the form. In VBA I use that number to delete the actual controls from the userform and reposition and rename the remaining lines of controls.
Private Sub Delete_Click()
Commandbutton3sub(CInt(Right(Delete.Name, Len(Delete.Name) - 6)))
End Sub
I'm using this code to remove controls from a panel.vb.net For Each c As Control In Me.pnlDevices.Controls Me.pnlDevices.Controls.Remove(c)Next
but somehow it doesn't remove all the controls at once, I have to run the code 3 times to remove them all(there is about 20 to 30 of them, mainly labels I don't know if it matters, but the controls where added dynamically at startup...
I need to get all controls on a form that are of type x, I'm pretty sure I saw that code once in the past that used something like this:
dim ctrls() as Control
ctrls = Me.Controls(GetType(TextBox))
I know I can iterate over all controls getting children using a recursive function, but wondering if there is something more easier or straightforward, maybe:
Dim Ctrls = From ctrl In Me.Controls Where ctrl.GetType Is Textbox
I have a winform with a main panel that is anchored top, left; dock: fill, and set to a specific size to contain another panel of content that we want to scroll through. The other panel along with a few other controls are on the main panel. Now, for some reason, after running the application the controls will be shifted down (never horizontally) some random amount. Now, the "random amount" may in fact be the last position of the scroll bar or something, but either way, it is unintended functionality. I have resorted to automatically resetting the locations of these controls on the main form in the constructor?

the code

I'm making quite the complex program, and while I try to figure out some more advanced methods that work better for what I'm trying to do, I'd like to learn how to do this (which is a bit of a roundabout method to what I've been trying). I'm wondering, how can I programatically create and remove objects? For example, I have webbrowser1. I want to remove it and create another webbrowser that I will also name webbrowser1. (therefore, the instance of the original must be removed)

I have a problem with a bit of code that is supposed to delete every controls on a form appart from the 2 first controls
vb2010
Private Sub ClearCheck(ByRef Container As Control)
Dim ctl As Control
Dim Boxtype As Control
Dim i As UShort = 0
[Code]...
The behavior is strange, I can't find any logic to it, it will sometime delete a part of the objects, other times it will delete other part of the objects. If I run it more than once, I can achieve the wanted result and remove all controls except the 2 I want to keep. It's as if it was checking 1 out of 2 controls.
To give you a better idea I have a combobox on the form and depending on choice it adds appropriate controls (not show/visible true) and add a second combobox to refine the search. If I change the value in the first combobox I want to remove the added controls from the previous combobox.SelectedIndexChanged as well as any control created by the following combobox from the form.
If need be I'll post the code that creates those new controls, but it's quite long so I didn't include it in this post
How can I group controls in my Form?
I don't need groupbox or panels, just something in the code...
To make it clear:
I have one form, Form1.
I have 3 buttons: Button1, Button2 and Button3, and I have 2 labels, named Label1 and Label2.
I have 2 "groups", in group1 there is Button1, Button2 and Button3. In group2 there are the two labels (Label1 and Label2).
But how can I program that, that if I write (for example) "Group1.Hide()", then everything In Group1 hides (visible = false). And so on with group2.
I programatically add a group of UserControls to a flowLayoutPanel control.
sometimes I need to destroy that group of controls, but have no idea on how to do it.
assigning the flowLayoutPanel variable to nothing only erases the pointer, but the controls remain in the window.I have found a page in MSDN saying that the best way to destroy a control is to call the DestroyWindow API, to destroy the container window. But I don't want to destroy the container window.
I have 53 text boxes in my windows forms application. I need to save the "text" of all the textboxes into a single file. Is there a way, I can control all the textboxes as a single textbox group and use its properties.
For example: Can I write something like :
For i As Integer = 0 to 52
Textboxgroup.text = TextBox(i).Text
Next
??
