I used the function - WNetAddConnection2A(n, UserName, Password, dwFlags) to programmatically map a drive and read the drive info out, and then used WNetCancelConnection2A(DriveLetter, dwFlags, ForceDisconnect) to unmap the drive. The first map and unmap were fine. But the next map will bring me the error 1202 - ERROR_DEVICE_ALREADY_RE...
Using WinForms and C#: I have a panel that contains a groupbox, some checkboxes, and textboxes. This panel is not always visible. Depending on user selections I show the panel. However, the screen is large enough that it requires scrollbars depending on your screen resolution. Does anyone know why the panel would move based on the Aut...
In my current company, we have this decade old...let's call it a "Hello World" application. While wanting to create a newer version of it, we also want to preserve older entries. These older entries contain hideous Word-generated HTML which was never filtered before. If and when we move to a newer system, I'd prefer to have that HTML c...
Is it possible to check for a right-click on a menu item in .NET? It appears that the framework doesn't expose it as an Event, but I've seen other applications (like Chrome and Firefox) which allow you to bring up a right-click context menu for a menu item. Presumably with a little event-loop magic you can do the same thing in .NET, ri...

The company I work for is currently developing a SEO tool which needs to include a domain or url Pagerank. It is possible to retrieve such data directly from Google by sending a request to the url called by the Google ToolBar.

I have a DataGridView that is bound to a DataTable. When a row in the table has an error (row.RowError is not empty), the DGV helpfully displays an error icon and tooltip with the error text. Instead of, or in addition to, this behavior, I would like to change the entire row color. What event does the DGV subscribe to in order to handle...
Hi, I am getting back again and again to it thinking about the best way to perform validation on POCO objects that need access to some context (ISession in NH, IRepository for example). The only option I still can see is to use Service Locator, so my validation would look like: public User : ICanValidate { public User() {} // We n...

Example: System.Web.Security.MembershipCollection implements IEnumerable and not IEnumberable<T>. Why doesn't it implement the latter, when it seems that it would be better (e.g. use LINQ)? Or, is it not necessarily better? ...
This is likely a novice question about LINQ, but assuming I have a set of Items with a DateTime property, one date having at most one item, how would I go about selecting the N most recent items from a date of reference, that is, the N items which have a date smaller that the requested date, and the largest date? My naive thought would b...
I have ~10,000 records would like to keep in a collection in memory and execute LINQ queries against it. This collection should be available for all the users in the application domain and can access concurrently. I’m looking for a .NET collection that supports multithreading can query asynchronously and efficiently without any threadin...

I've used Reflection.Emit in the past to write a compiler, but I know the standard compilers don't use it, and in an answer to another question here I saw a mention that there are some things Reflection.Emit is unable to do. What are the limitations of Reflection.Emit that I should be aware of if I plan on writing another compiler for ....
