View 4 RepliesAlright, I currently have a listbox being populated with a variety of files.What I'd like to do is select a file, click the add button and populate the item name into that textbox.Then, select another item, click the add button and populate that items named into an empty textbox.I can get the first textbox to populate, but once I select the second item, I can't get empty textbox to display.
Here's my current code on how I'm populating the first textbox. The commented out section was for adding those items into another listbox, which worked but I need to specify a custom order, which I was I thought adding each item to a textbox.

I've got a BindingSource for a DataSet. I'm fairly new to this whole binding business and databases, and it took me hours to figure out how to use BindingSource to get to an item, because the Row method was not included in the autocomplete. Not to confuse anyone, here's some sample code:[code]The code runs perfectly and does exactly what I want. My problem is the following: When I've typed in source.Item(0)., autocomplete does not display Row in the list. Is this perhaps not the best way to do what I'm doing? Is there a reason it's hidden? Is this a good coding practice to do so? The fact that is wasn't there took me lots of time Googling, so I'm trying to figure out whether it's a Visual Studio glitch or my own.

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

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

My client wanted to have a textbox in the Customer form of the application, which offers the applicable endings to a started street name. He starts to type a street name and the textbox offers a list of streets which start with the char sequence he typed into the textbox. Textboxes have the AutoCompleteCustomSource property and even though a list of common street names will be longer than it could be pre-filled on start, I could just hit a database with a query, populate an AutoCompleteStringCollection and show that to the user.
Now here's the thing: If I make the list populate on every keypress/keydown whatever, the program crashes and throws an AccessViolationException. I've found out that that's because: The control is in the middle of showing the AutoComplete list when at the same time it is being modified, resulting in the crash. When you refresh the Autocomplete List, the control is recreated with new pointers. Keyboard and mouse events (KeyPress, MouseOver, MouseLeave, MouseHover) attempt to reference the old control's pointers which are now invalid in memory causing a memory access violation to occur.
The underlying AutoComplete implementation does not allow for changing the AutoComplete candidate list object once it has been set on a window. To allow changing the list, WinForms destroys the Edit control or ComboBox and recreates it. This causes an exception if the underlying control is destroyed while the AutoComplete window is still use it. I read about this on MSDN, their resolution: Do not modify the AutoComplete candidate list dynamically during key events. I know that you can do this by creating a custom control and such, but can it be done with just pure coding wizardry?

I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.
