View 1 Replieswe're working on a billing systemCurrently I am working on the categories module. Here's the thing:I need a dynamically changing UI. So the user can add categories, delete them and teh UI would accordingly add or remove controls automatically.I used DataGridView, but since the fetching and storing of data will not be done in a database, I need to fetch it and update it using an HTTP API, the data bindings are causing problems as I need to update, Insert or delete data using functions instead of letting VB do the hard work. I tried creating a datatable and checking for changes everytime user added/deleted/changed a row, but again the problem is: in a datatable I am not able select what type of control represents the column. For Example I have a parent category column where the control needs to be a combo box. The datatable's columns don't seem to provide an option and are automatically set to text box.I am thinking there is a really cool way of doing this that I am unaware of. all the VB.NET books I have read only seem to use DataGridView in conjunction with some sort of a database and not independantly.

If a billing period always starts on say the 22nd of the month and ends on the 21st of the following month then all I'd have to really figure out is how many days are in the month the billing period started right? I hate working with Dates! This is what I've come up with using the idea above...Note, Dates are strings in the first column of a Listview in the format of, mm/dd/yyyy.
' get month from start of billing period (last item in LV) ' example of dates: 06/22/2011
Dim BillStartMonth = CInt(ListView1.Items(ListView1.Items.Count - 1).Text.Substring(0, 2))
' get Year from start of billing period (last item in LV)

I am creating a sound shop application. The user will first select an album from album list box and then from there a list of songs from that specific artist will end up in the song list box. The user will then be able to add that song to the shopping cart. After confirming the purchase, the songs that were bought will appear in the play list box so the user can listen. I am confused on how to get this to work properly.

Win7 64 bit; fully patched VS2008 targeting FW2.0; VB.Net; running in Debug Mode (not tested in Release mode)I have a resonably complex app which I am refactoring a bit. As part of that, I relocated some code from a subroutine into a Click Event Handler. The Event Handler will, late in the handler, call the, reduced in function, subroutine. The point of this is thatNow when I click the button associated with the modified Handler I get:A first chance exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll<br />With Error System.AccessViolationException Attempted to read or write protected memory.This is often an indication that other memory is corrupt.

All functions of the app, except those that start from the buttonclick in question, work as before in the problem version.The problem persists after rebuilding the entire solution, after restarting VS, and after rebooting the PC.
