• Game Technologies: DirectX, XNA, XACT, etc. Tutorials Thread

  If it's not too much trouble, could this topic be stickied I am just wondering if we could have a main thread that carries links to all the tutorials. In other words, someone makes a thread with a new tutorial, and then, they post the link to it here with a description of the tutorial. That way, others don't have to search through a whole forum for just one topic. Just an idea to make it easier on everyone.   On a side note, I plan on linking this thread to another thread titled: First XNA Program Development Team (FXPDT). Take a look at it. Thanks for your time. Also, I've added some tutorials for you all for now.   P.S. Since the tutorials are publicly viewed and linked to, I don't think you need permission to ...Show All

• Visual Studio Express Editions VC# hangs after creating new project

  Okay, this problem didn't happen the last time I installed VC# (some 6 months ago). Recently, I downloaded the VC# Express ISO (2 weeks ago), and installed it. But it hangs as soon as I create a new project. Did Microsoft change the ISO files or something Here are all the wierd things that are happening in my VC++ Express and VC# Express 1) I installed VC# Express first, it hangs immediately as soon as I try to create a new project. It just says it's creating a new project and hangs. 2) I tried uninstalling every sign of VS Express and then reinstalled first VC++ and then VC#. The problem still persists. 3) Right now, my VC++ Express install fails to install the MSDN Express Edition component. 4) Even after closin ...Show All

• Visual C# Simple Question regarding Objects

  I'm a bit reluctant to post this question in the forums because I know that the answer is going to be something fundamental, but I've come to a point where I simply can't continue programming without having it answered and after hours of searching I'm at an end of what to do. So here goes: How can I access the properties and methods of an object from a class other than the class that the object was created in. For example, I create a new object (called object1) in a class (lets say Entity.cs) and this new object, object1, contains a method called update. Now here's the problem, I want to call the object1.update method from a class other than the Entity class (for example Other.cs) how can I do this without creating a new object in the O ...Show All

• Architecture security data between layers

  We are designing an application with sevreal layers. Data Business Logic Services Client - Gui ASP.NET or WebServices Wea re thinking of authorization in the BL and maybe in the Data layer. our problem is tramsfering the current data between the layers in an easy way. Any ideas In other words, you're not trying to secure data but rather are interested in auditing. Auditing is one part of an overall security methodology, but you should be clear about what threats you intend to handle, and which ones are out of scope. With that said, in order to log which user did what, you need to have that information available. The design for this functionality differs between Win and Web scenarios, although you could ...Show All

• SQL Server Conditional formating in Subtotals?

  I have subtotals in a matrix and I want to format the background color depending on the subtotal value - > 95 = "Green", < 95 > 90 = "Yellow", < 90 = "Red". I go to the Subtotal properties and put the iif expression in the background color, but it's not detecting the Subtotal value. How do I refer to the Subtotal value in a formating expression Yes, I created the subtotals by right-clicking the row cell of the outer-most group and selecting 'subtotals'. The problem with the simple iif... is that it affects all the cells - not just the subtotals. I did find out why my background image wasn't showing in the subtotals, if you set a background color in the Subtotal ...Show All
