For Each ThisCtrl As Control in Me.TabControl1.Controls
TabControl1.TabPages.Remove(ThisCtrl)
Next
I run this code on a form close to reset the tabs to nothing (I load them dynamically) when I open this form again one tab is still there!
the funny thing is that I checked the count before it loads anymore items and it's still 0 tabs and after 3 are loaded (which could be any number) it says the count is 3.
but it shows four...I could only imagine that the problem is with microsoft..
How can be find out which file is going to delete when, user provides command like DELETE or SHIFT + DELETE or by programmatically gives DELETE command. Well I know about FileSystemWatcher Class, but this class doesn't provide information before delete...
I'm trying to delete cookies from my webbrowser control with this code: Form1.WebBrowser1.Document.Cookie.Remove(0, (Form1.WebBrowser1.Document.Cookie.Count - 1)) I think this works (not sure how to check) but if my webbrowser doesn't have ANY cookies yet, it shows this error: System.ArgumentNullException was unhandled
So basically, If my code is correct, I need some sort of error handling to check that there are cookies (if that is the issue?). I tried this code but it shows the same error: If Form1.WebBrowser1.Document.Cookie.Count > 0 Then
Form1.WebBrowser1.Document.Cookie.Remove(0, (Form1.WebBrowser1.Document.Cookie.Count - 1)) End If
For some reason a control on my form has disappeared. I can select it in the properties window and view all the properties (Visible = True) but I can't see it. It also doesn't appear when I run the form. How can I delete it, or bring it back?

I have a ListView and I have set up my Delete Link button. When I clicked Delete however I get "The ListView 'ListView' raised event ItemDeleting which wasn't handled." So I decided to try and implement the DeleteLinkButton_Click() and ListView_ItemDeleted() ... however I can't figure out how to identify which row I've selected for my DeleteLinkButton_Click().
I didn't bind my source through a control instead I used the following method.
I've tried the following code but it doesn't delete and no error message received.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click Dim Station As String = "" For Each sItem As ListViewItem In lvList.SelectedItems
This works fine, unless I have Windows Explorer open and I'm looking at the 'MySubFolder' directory. Then I get an IOException The directory is not empty. - clicking OK dismisses this and then the folder structure is not deleted. Any thoughts on how I can get this to perform correctly (i.e. delete), even when running this code while having the folder struture open in Windows Explorer?
I have a datagrid being filled by the data adapater connected to my database.I have a delete button on the form, i cant figure out how to delete the selected row on the datagrid when the delete button is clicked.
I'd like to create code for my datagrid view to be able to delete a row by first clicking the record selector column then pressing delete. Seems like some standard stuff but really difficult to create in VB 2005.
I'm trying to delete a number of records in a table from the last and forward. My idea is to use sql like this: delete top " & variable & " * from table where ID = something It gives me a general sytax error. Is it at all possible? Fuga. Edit: I also have the order by statement there. I just forgot to put it in the question.
I have a BindingNavigator and combobox tied to the same BindingSource. I want to allow the user to confirm a delete after hitting the delete button of the navigator. It appears that the row gets marked for deletion after my BindingNavigatorDeleteItem_Click event handler is processed. Is there no way to cancel the delete activity from within the delete click event? If not, then it becomes necessary to store a delete flag and catch another event to RejectChanges.
my deletecommand delete all my rows whenever i delete a row..but when i view it again the other rows still there and the i deleted is actually deleted.[code]

In the following code when the Element ("title2") is deleted the Attribute(("TEST") on another node doesn't get delete. If you remove the xnode1.RemoveChild(xNode2) (that deletes the element) the attribute does gets deleted. why I can't delete the attribute when I delete the element on another node?

My apologies I have posted this in the wrong catagory It should be in VB.net, my mistake)Hi guys I posted this question at the end of another topic I started but I think it will be over looked as the origional topic was solved of the dreamincode community You must all be getting sick of my quexstions by now haha I suppose you don't learn if you dont ask.

I created a program which was deleting a particular directory for me. The program was compiled and working. Today I run the same program...did not do any system updates and now it won't delete my specified directory. I ran tests to make sure the directory is there when testing...I keep getting access/permission errors.
I rebooted system, ran my application...still gave me error. I turned off Windows Defender...still got error. If I manually delete the directory...no problem.
Is there a way to get system permission to delete the directory? I am being given an 'access denied' error...I do not have permission. I tried running my application as administrator...no good. - VB 2008 Express - VISTA OS
I have just watched a Microsoft tutorial at [URL]..It shows a simple dragging on of a dataset to a form with the biniding tools.
If I were to do the following: Click Add button Enter new data Click Save Button Click Delete Button
[Code]...
It appears that the Save button must be clicked after the delete button has been clicked. Is this the way it is designed to be or have I got some settings wrong somewhere else ?
Here's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.
