I have a DataGridView (called DataGridViewSecurity) in VB.net (Visual Studio 2010) which is bound to a DataTable (called DataTableSecurity) in a DataSet (called DataSetSecurity). I have added a nonbound column (called nSecurityComboBox) that I set based on an integer field (called nSecLevel) in the DataTable. After setting the combobox, it doesn't display anything in the combobox, but when you select the combobox, the 5 values in it's items collection show. Here's the code I'm using to add a record to the DataTable and then to set the combobox:

I have a VB 2008 program that was converted from VB6. I used an AxMSComCtl2.AxAnimation COM control to show a simple AVI file (no sound) in VB6. Is there a .NET Framework control that I can replace this old control with? I have found the MediaElement that looks like it can only be used in a WPF Application. There is also the Media Player Component which seems to also be a COM component. So, I don't see the advantage of switching to that.

I would like to know if there's anything that can display data differently than what's stored in the DB.Here's my example. I have a column called Active and in the DB table, 0 represents Active, -1 represents InActive.In my report, when showing whether or not a listing is Active, I'd rather have the words Active and Inactive rather than 0 and -1.
I'm working a backup program and to determine the destination location, I give them the choice to type it in, or browse to it. Lately, I've been getting this error after they browse to it using the FolderBrowserDialog to set the location and the containing form is closed:

I am working on an ASP.Net website and have a GridView displaying some data,in the OnRowDataBound event I am setting the border of the row for certain rows based on some criteria. This all worked fine when I was testing my pages locally, however when I put these pages within our master page (this is part of a company intranet site) the row borders disappear in IE yet display fine in firefox.
Is there anything that could be causing this? So far there is no CSS style applied that I know of as I set the border inside the event handler like so:
In C++ it is fairly simple to display the actual value of a pointer to an object. For example:
// hope this makes sense: (please edit if not) void* p = New CSomething(); cout << p;
Is there a way to do something like this in .NET?The value of doing this would/could only be educational, e.g. for purposes of demonstration as in displaying a value for students to see rather than just comparing for reference equality or null (nothing) to prove shallow copies, immutability etc.

Can anyone possibly take a look at my code (below) and tell me what I'm doing wrong? I have been sitting here for hours trying to figure it out. I'm very new at this and I'm thoroughly confused. I am using a book for Visual Studio "Programming in Visual Basic" and I have gone through all of the tutorials and code examples and followed them exactly (at least as far as I can tell). However, whenever I run the program, I am not getting the sum of the quantities I assigned to the constants showing up in"AccessoriesTxtBx" as I'm trying to. It shows up as $0.00 even when I have checked the boxes.[code]
It appears my connection to the db is correct when I select different options the datagrid displays the correct number of records. So I am not sure why I can not see the data in the grid.[code]....
