I am building a WinForms application. On one user control I have a CheckedListBox on the left and a ListBox on the right. Within both controls, the selected item(s) become completely transparent. Not only transparent, but if I was to click within the transparent area(s), I would actually be clicking whatever is underneath the application. So, if the WinForms app is loaded up and sitting on top of a browser, when I click one of the items within either list control, I could actually click a link within the browser underneath. At first I thought that I had changed a setting of each control. I thought there might be something like SelectedItemTransparent = True/False, but upon further looking, I think it might be an application-wide setting. I have confirmed that it isn't just this one machine. I have loaded the project into VS 2008 on both my laptop and desktop with the exact same results.
I have a user control which contains several buttons and a listbox. Clicking a buttondetermines what items are in the listbox. When a user clicks an item in the listbox I want the selecteditem passed to the parent form.

For example:

In VB.NET, I am trying to talk to a webservice (that can't be changed) to create and update customer data.The CreateCustomer service expects an object of type ConsumerPerson and the ChangeCustomer service expects an object of type ChangeData.The properties of these two object are exactly the same, so I thought it would be wise to just set the properties using one single function.

In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.

Currently, I have a listbox lstInventory where I have loaded some database information from a .mdb file. I am able to add new records, and they all display correctly.
Yet, I can't seem to retrieve or access any of the listbox items. (Not trying to reaccess database in here, yet). I am hoping to "Edit" an existing database record by matching it to the lstInventory's selecteditem property. Unfortunately, I am not able to retrieve anything (tried traditional CType(lstInventory.selecteditem.ToString, String) approach, as well as a debug.write approach (which I can't seem to display, even with a Listener-which is another issue in itself).
Furthermore, when I check the listbox.items.count property, it prints out as a "0" [using a messagebox.show()]
I have tried searching multiple forums, but found lots of "database into listbox" threads, and the MSDN website hasn't helped me yet. Do I need to know the collection's name (what would it's name be based on ?)? Or am I not converting the object into a printable/countable quantity?
I am trying to load the text file to the ListBox Object. But it doesn't work.
