I have a winform app which render a few charts, based on the user selection. I want to simulate an ajax style loader such that when the user makes a selection, there will be an overlay on the form with an animation in the center.

When the application is run, the DataGridView is bound to a DataTable. Later I add more columns to the DataTable programmatically and it is reflected in the underlying data - i.e. the column Ordinals are as they should be. However this is not reflected in the DataGridView. Instead columns are appended onto the originally generated set. ...
A .NET application I'm writing needs to store .NET float, double, and decimal datatypes in an Oracle database. When defining a number column type in Oracle, you have to specify the precision and scale of the number: NUMBER(p,s) p is the precision, or the total number of digits. Oracle guarantees the portability of numbers with precis...
I've got a guy who is a wizard at writing stored procs and he can munch 10 tables down to a single column in no time at all. I'm half tempted to invest a couple of days to work with him on returning XML instead of rowsets because I can digest those all day long without any problem. I say that because it is a challenge to get a result of ...
I'm to get a custom DateTime format including the AM/PM designator, but I want the "AM" or "PM" to be lowercase without making the rest of of the characters lowercase. Is this possible using a single format and without using a regex? Here's what I've got right now: item.PostedOn.ToString("dddd, MMMM d, yyyy a\\t h:mmtt") An example ...

Apparently some vendors (like Telerik) are working on versions of their controls that do not rely on postback behavior to work. As in the latest release of Asp.net MVC RC also code behind files tend to fade away for views, what would the best way for vendors to encapsulate UI rendering (control tags, html helpers) and control behavior...
I added a simple dialog window to the install's UI with textboxes. How do I find out what the user entered? @Mitch Wheat: Thank you. I managed to solve the problem with your help. But I think you failed to mention that I need to use the CustomActionData property of the Custom Action. ...

Does anybody know of a good (hopefully free) class to replace the .net SerialPort class? It is causing me issues and I need one that is slightly more flexible. See my other thread about my issues, but essentially I need to suppress the IOCTL_SERIAL_SET_DTR and IOCTL_SERIAL_CLR_DTR commands from being issued when I open the port, so I n...
How come App_Code is not a choices in the Add ASP.NET Folder submenu in the VS solution explorer? I realize you can create one yourself manually by just renaming a New Folder, but what is the rational here? Is this not where you are supposed to put "utility" or "service layer" type classes? On a MVC project side note. I do like the fact...

So, [WebInvoke(Method = "Delete")] is not equal to [WebInvoke(Method = "DELETE")] This mistake was causing a ProtocolException: System.ServiceModel.ProtocolException: The remote server ret...
I've been doing a lot of research on how best to write "correct" network code in C#. I've seen a number of examples using the "using" statement of C#, and I think this is a good approach, however i've seen inconsistent use of it with various expressions. For instance, suppose I have some code like this: TcpClient tcpClient = new TcpCl...
(Was: ASP.Net codebehind not finding controls on the web page) I'm using VS 2008. I don't know what secret switch I need to flip, or what trip wire I accidentally tripped over, but the last form I created in my project is misbehaving very seriously: the codebehind is apparently unable to find any of the controls that I have set up on t...
