• Visual Studio Express Editions BindingManagerBase Position_Changed Problem

  Hey Everyone, I have a program that has several textboxes bound to 1 dataset which contains only one table. When the form loads, the data is displayed in the textboxes allowing the user to add, edit, delete, etc., as well as navigate through previously entered records. However, when trying to navigate through the records, it doesn't do anything. The recordCountLabel, which keeps track of the record number that is displayed, changes, but the first record stays on the screen. Here is a little of my code. Protected Enum Record RecordNum DDate Shift ATO Vehicle End Enum Private Sub Form_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase .Load 'Loads data into the 'TripSheetI ...Show All

• Architecture Using Object Relation Mapping Tools

  I am planning to use Object Relation mapping tool in our project, presently we zeroed on Nhibernate. Just before implementing i want to seek advice on the below points Any cons of using OR mapping tools Any known issues Any performance issues TIA, Sudheer. The answer to all your questions is Yes. If you do not intend to use the Domain Model Pattern, then O/R mapping is probably not for you. If this is your first time implementing a Domain Model, I would suggest reading the book Domain Driven Design by Eric Evans, or Applying Domain Driven Design and Patterns by Jimmy Nilsson, BEFORE you get started. More importantly, if you haven't tried persisting objects yourself, then you might ...Show All

• Software Development for Windows Vista Draw buttons cleanly on Aero Glass

  Using Vista RC2, I've been digging into Aero Glass and the DwmExtendFrameIntoClientArea function. That much has worked nicely and I've got a glass area at the bottom of the form. Now I'd like to add buttons to it. The problem is that the button is drawn with an opaque white border and transparent text. I've tried owner-drawing it using a variety of DrawThemeBackground/DrawThemeText (etc) functions, but no change. Am I attempting the impossible, or is there a correct way to draw the button that I've missed Thanks! Rob Most GDI functions produce incorrect alpha values in the destination surface, and therefore are not suitable to draw on glass. So if you want to use controls, you need to ...Show All

• Internet Explorer Development A problem with IWebBrowser2:Navigate() under IE7

  I have a problem with ie7, the method Navigate of interface IWebBrowser2 can't work as before. My application is a C++ one, there is a Browser control (BrowserObj1) which is created in the main thread, hosted in the main window.

• Game Technologies: DirectX, XNA, XACT, etc. Integrating Joystick

  Hello, I am fairly new to the .NET platform and currently using VB.NET to read joystick input. I am using DirectX 8 and following a reference I found on MSDN. However, this piece of code is generating a run time. EventHandle = inp_device.CreateEvent( Me ) EventHandle of type long, inp_device is of type DxVBLibA.DirectX8. The exception generated reads as follows: Cannot cast windowsApplication1.joystick_controller to a DirectXEvent8 object. I would appreciate any direction in this matter. Thank you, Nath I'm really susprised you could find good DX8 documentation. You should be using ManagedDirectX 1.0 or XNA (which is the only other managed alternative). Right now though XNA is only supported with ...Show All

• Windows Forms Catch all Exceptions

  Hi I have a program with several Forms. What I need is to log all exceptions (save them into a database). Is this possible without having to write a "try{ ... } catch(...) {...}" everywhere (and call a static log-method within the catch-body). Kind Regards i have seen ThreadException and the other related to AppDomain exception but is it really useable for windows apps for unhandled exception scenarios i'd rather catch it in the proper places where i expect them to be raised, in my opinion. ...Show All

• SQL Server A thought this would be simple...

  I had originally thought a full outer join would solve this, but alas I'm a roadblock. Perhaps it's because it's a Friday! The goal is to create the most efficient query that will display results of the daily calls and sales as this: Date EmpID Calls Sales 7/1/2006 1 20 5 7/1/2006 2 25 7 7/1/2006 3 NULL 1 7/1/2006 4 10 NULL The problem is a simple full outer join ends up ignoring EmpID 3 who has no Calls in t1, but I still want that row displayed in the results. Any ideas TIA create table t1 (Date smalldatetime, EmpID int, Calls int) create table t2 (Date smalldatetime, EmpID int, Sales int) insert into t1 values ('7/1/2006', 1, 20) insert into t1 values ('7/1/2006', 2, 25) insert into t1 values ('7/1/ ...Show All

• .NET Development CPU problem for multiple TcpListener's running on separate threads?..

  I have a Windows Service which runs multiple TcpListeners, each on its own thread (approximately 200 concurrently). When I am running the service on my dev machine (XP Pro SP1), regardless of the number of client requests at any given moment, everything is fine. But on the other servers which have Windows Server 2003 Web Edition SP1, the same service sometimes consumes 100% CPU for half a minute to half an hour when there were NO requests from clients. This happens both in production (Release configuration) and when I run it in Debug mode from VS 2003 IDE. Then CPU usage drops (again, without any obvious reason), and can go up again in a few minutes. There is no pattern in that behavior. There are no other programs running on thos ...Show All

• SQL Server Reporting Services Instance not found
