I have a window which has 8 items in a listview along with 2 radio buttons below the listview. The user is able to select one or more selections in the listview and turn the selection on or off with the radio buttons(live, prior to hitting the submit button), my question is how do I tell which selection was changed? I was going to put the one or more selections into a string/array and use that later for some messages once the user hits the submit button. I can almost think of it but can't quite get there, i'll be using an if/else with the .selected option in listview items but am not sure how to tell if the user, say,goes back and changes the option from On to Off(Off originally)to remove that option from the array.
im trying to add a text changed method to my listview item. all the items are dynamicly created so i would think id have to use an addhandler listviewitem1.textChanged addressof listviewitems_click where listviewitems_click is the generic sub to handle the click. but the listviewitem control doesnt have a text changed event, but you can rename the text in the control anyway.
I want to know how I can check with the listview item on my main form to see that if the text property of the selected listview items has got the same text property of the listview on the another form?
I used this:
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim i As Integer If Form1.ListView1.Items(i).Text = Me.ListView1.Items(i).Text Then
[code]....
The item I have been added after I have got the same item as my form1.listview.items and form2.listview1.items. How can I find with both of the listview items that if both have got the same text property similar as I have created? I am not sure if the form1.listview1.items(i) variable is incorrect.

I want to know how I can check the string 'enabled' in my php page for each paragraph while being matching with each listview items that i have extract the strings from my php page?
Here's for an example: i check the string 'enabled' in paragraph one and if it does have it then tick the checkbox on the listview item 1 otherwise untick.
i check the string 'enabled' in paragraph two and if it does have it then tick the checkbox on the listview item 2 otherwise untick.
i check the string 'enabled' in paragraph three and if it does have it then tick the checkbox on the listview item 3 otherwise untick.[code]...
I am creating a program in which there is a listview control with many items contained in it. It also has checkboxes for each of them. I am trying to get it so that when you check the checkbox next to an item, it removes the item from the list. I am using this code:
Private Sub ListView1_ItemCheck(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck ListView1.Items.RemoveAt(e.Index) End Sub
When I run this however, and check an item, it gives me this error (I am checking the first item in the listview, which would mean the index is 0): InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index
I've have been testing this code out for both the listview events ItemCheck and ItemChecked. How is 0 out of the index range? Wouldn't it be the first item in the listview, in which case it should remove the item.
When I have a listbox full of items and scrolled such that topindex is not zero/first item, changing the value of the top item causes the list to scroll up by one.I can compensate for that easily by changing topindex after the listbox1.items(index)=value statement, but does anyone know why it happens or if there is some property I'm overlooking?
I'm using a textbox to supply a filter for the datasouce which is bound to a listbox. It works (mostly) with a few exceptions, one being i was to restrict the height of the listbox to the number of entries (upto a maximum number), so a bit like a combobox (which in effect is what I'm writing). One of the problems is when the number of entries changes there does not seem to be an event raised, although the OnDrawItem is called for the items to be displayed (the displayed ones!) Is there anyway to find out (in a derived listbox) when the number of entries has changed in the datasource?
View model base has an ObservableCollection of tabs type ViewModelBase. The Tab Control itself is binding fine to these, displaying appropriate view models. I have 2 problems however, I want a "NotepadView" (Of type viewmodelbase) to be replicated numerous times (one view many view models).
At the minute, I have 4 views (NotePadViewModelx where x is 1-4) with corresponding viewmodels, this is because each view had the same text per tab. Now I have individual views per tab.
When I type into tab 1 and switch to tab 2, I lose what I typed in tab one when I click back.
Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString
Using .Net, I need to generate a response based on only the checkboxes on my form that have had there states changed. So how do I know if the check box has changed from its previous value before submission. I can't use the onchange event because the user may check multiple boxes before submitting.
I am trying to check if an image has been changed from a picturebox in a if statement. If I cant check if a image has been changed then can I check if a picturebox been clicked.

I have a combo box with "yes" and "no" with i select Yes i want the label2 to change the text to "yes" likewise with "no"
I've tried to code it in a logical way as possible but it just doesn't works except for the "wtf" so i think that overall my code is correct but the way i want to retrieve the selected item from combo box is wrong.

Is there a way to check if the date time picker has been changed? I have a date time picker set to allow a person to put in their date of birth and I have it set to no greater date than 12/1/1992, but I need to check that the user has actually selected a date before the form is submitted. Can it be checked?
I know I can exit a program by using the End statement.
But i was wanting to know how to check to see if the data has been changed since it was loaded and bring up a diaglog box up saying the data has been changed or not saved, would you like to save the data before exiting?

I have a problem with the Validation of a Integer-Field in my application.Its an Access DB on a Windows Form.I implemented the validation in DataSet.vb using an ErrorProvider on my Form.The field name is FNr and should not accept duplicate numbers.If the field value is changed, a query checks if the number already exists in the Datatable and if so it sets the error on that field.If the user tries to change the field to a number which is a duplicate I want to cancel the input back to the original number. This works but the
Error message is still shown by the ErrorProvider.The code is partially in DataSet.vb and in Form.vb

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
