• Game Technologies: DirectX, XNA, XACT, etc. 360 Dev do's and don'ts

  Hi, My primary platform at the moment is Windows, but I want to ensure I don't code anything that is going to cause alot of pain when I eventually get around to subscribing to the creators club and deploying to the 360. I've read a couple of articles on GC and other performance related stuff, but I wondered if anyone has any advice generally on what to avoid or if there are preferences in how ceratin things are coded (e.g. there are many types of storage, is one better than another for XNA specifically) that will mean the transition to 360 is as smooth as possible. Any thoughts or comments welcome! Cheers :) Ska Software wrote: I did; it turns the game into a slideshow :) I'm not sure why it's gotte ...Show All

• Visual Studio 2008 (Pre-release) Dynamic creation of LINQ

  Hi guys, I finally had the chance to try out LINQ and think it's a very cool tool. I have already finished one of my projects using LINQ for XML. Now I am working on another project and am using LINQ for SQL. Is there a way you can dynamically create the DLinq object I asked so because the object I'm creating will be used against 2 projects (with two different databases). And possibly a third and fourth database later on. To get a better view of my problem, here is what I'm trying to do: I want to create a library that will return an object. This object can be a list, xml, or whatever the calling application wants. For now, the types would be list, xml and dataset (and most of our internal applications will use xml). The value/data insid ...Show All

• Visual Basic Sending unicode characters to an application

  (This thread was "moved" to this forum) Hi, I'm creating an application that detects the pressed keystrokes and sends other characters in their place. Just like a key mapper. I'm using a keyboard hook to detect the keystrokes (the one from here , if you need to know) and and then send other keys to applications system-wide. My only problem is that I need to send non-latin characters, cyrillic characters to be more precise (in my case), and I have realized that I'm not able to simulate this the way I'm doing so far. I have researched a lot and the only thing I found was that I may have to use SendInput instead, or Windows Messages to send a WM_CHAR or something like that. My main objective is to be able ...Show All

• Software Development for Windows Vista Problem with Rules and comparisons on nullable types

  I'm building an application (using .NET 3.0 RC1) where I want to allow my customers to create simple Rules to do a consistency check on amounts on an invoice. They might create a condition like this.totalAmount > 500 to flag invoices that total more than $500.00. This works OK. But they also need to be able to check whether the total amount is more than the total amount of the last invoice, which would be a condition like this.totalAmount > this.previous.totalAmount where I set previous to be a reference to the previous invoice. This also works OK, except for one case. At times there won't be a previous invoice (for example, the oldest invoice in the database won't have a previous invoice.) Of course, we could add a ...Show All

• Visual Studio 2008 (Pre-release) Bubbling an Event from WPF to Winform

  Hello All, I have a WPF canvas which is hosted in an ElementHost (I am using this WPF canvas in a .NET 2.0 application using System.Windows.Forms.Integration). I want to bubble the occurence of the MouseDown/MouseMove/Drag/Drop events of the WPF canvas to its superbase control which is basically a C# .NET 2.0 class (which is hosting the ElementHost). This superbase control is winform user control that inherits from System.Windows.Forms.UserControl. So the hierarchy is WPF Canvas is the Child of ElementHost which is added to superbase control (using this.Controls.Add(ElementHost)). Firstly, can I bubble up the event from WPFCanvas to the winform based superbase user control If yes, How will I handle the change in eventargs declaration ...Show All

• Visual Studio Team System Merge Error - TF14085

  When we try to do a baseless merge we get the following error TF14085: Cannot merge $/Path1/Branch1 to $/Path2/Branch2 because there is an incompatible pending change (not edit or encoding) at $/Path2/Branch2$/Path2/Branch2 already. Why do we get this error Is there something wrong with Braching Thanks, Srikanth Obvious question first: are there any pending changes in Branch2 Undo them before trying to merge. There are a few cases that can lead to TF14085 being thrown for trickier reasons, but they shouldn't be possible during baseless merge. Post the exact command if you can, along with any relevant history. ...Show All

• Software Development for Windows Vista Automatically discovered printers raise multiple JobAdded events

  Howdy, I'm a little new to interoping, so I need a little help. I have a WaitCallback method that raises an event whenever a job has been added to the print queue on the local machine (generally a print server). The primary purpose is to pause all incoming jobs so they can be properly logged, and then released afterwards. The jobs are stored in a queue in a separate SQL database. This is all well and good when a user adds a printer through the "Add Printer..." dialog. However, whenever UPnP discovers a printer and automatically adds it, the jobs sent through that device raise multiple JobAdded events. As an example, let's say we have a Xerox Document Centre 432 on the print server \\beast . If I share this printer on a ...Show All
