• Architecture What is SOA

  Service Orientated Architecture is being touted as the next big thing in the IT world. I decided to do my masters dissertation around SOA. I was quite surprised to find that there is no clear definition of SOA. As a start point I am trying to come up with a definition of SOA that will be used to inform the rest of my research. Can you offer a short definition of SOA If so please go to my blog (or respond here) and comment on this question and if you want on any or the other research questions. http://www.akintola.net/MyBlog/CategoryView,category,SOA.aspx Make sure that you leave your e-mail address if you want a copy of the completed research.

• Windows Forms AutoScroll for Panel control and refreshing while scrolling

  Hi, I'm writing a small app using VS2005 in C#. I put Panel control onto my form and, as child control, another panel inside it. I'd like to see as the content of 'container' panel changes its position during scrolling, but when I set AutoScroll property to 'true' the effect is only seen when I stop scrolling the content (it depends on 'show window contents while scrolling' settings of operating system, on my computer it's set to false). So, to do that, I consumed Scroll event from the container and set location of the child panel using ScrollEventArgs values. Everything works fine until I stop scrolling. After that, scrollbars of the container change their sizes and 'everything breaks', colloquially speaking. I've tried to do something wi ...Show All

• Visual Basic Information on working with services

  Hello, I was wondering if anyone could point me in the right direction for writing a wrapper app that interacts with a service we're developing. All I'm looking for is a general management program akin to the way Microsoft SQL Service Manager works with the MSSQLSERVER instance, although a more in-depth look at interaction with services would greatly tickle my interest as well. For now, however, just simple syntax on how to start, stop, check the status, etc. of a service would be wonderful. Hi, take a look at ServiceController class . Andrej ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. These two methods are missing in the XNA Framework?

  Aren't these two methods just missing from the framework Please add them. Plane.Intersects(Ray) Ray.Intersects(Plane) These two should return a Vector3 for information about where the Ray hitted the Plane. (I've also added this feedback to connect.microsoft.com). I'm not sure they should return a vector though - collision detection with rays may consist queries formed in many different ways: 1/ Does x intersect y 2/ How far along x until it intersects y 2/ Where does x intersect y Generally ray queries return a float, as it covers all of these: 1/ either null or a negative distance 2/ the float value 3/ point = ray * <float value> ...Show All

• Visual Basic Display Same Object In Different TabControl Page

  Currently i have one databasegridview in tab page1, how can i bring this databasegridview to the other tab page Thank you. This first example is for when you add the datagridviews during the designtime. There is a TabControl with 2 pages, DataGridView1 on TabPage1 and DataGridView2 on TabPage2. Notice how the event sub is set to handle events from both datagridviews by listing them after the 'Handles' keyword at the end. If a column's width is changed on DataGridView1 or on DataGridView2, then the event has code to update both datagridviews so the layout will look the same on both datagridviews. ...Show All

  I can use the Visual studio's debugger to check the .exe file which calls the .dll, but how can I debug the .dll file The debugger can't go through those codes in .dll. Thanks!

• Visual C++ VS05 saying project (unmanaged) is out of date and needs rebuilding when it has just been built

  Hi all Can anyone give me an idea of how to fix this somewhat annoying problem I have several projects in my solution. All are C++, some are managed and some are native. When I try to run the program - even if I've just done a build - it tells me that several of my projects (all the native ones) are out of date and need to be rebuilt. When I click yes, it will go through these projects and run the linker (at least the output window says "Linking..."). The linker doesn't actually do any linking (takes about a second to finish) and then goes on to the next project. Once its finished all the projects it will start running. If I stop running and then try to run it again, I have to go through the same process. Does anyone ...Show All
