Software Development for Windows Vista Help! a confused trouble about my cumstom activity.
hi, I am coding a custom activity, which has a DependencyProperty named myProperty1. and this myProperty1 is a subclass of DependencyObject in the same assembly. My custom activity works well with Designer. However, while i run the assembly compiled from the XAML file generated by Designer, it allways fails. Then i disamble this assembly by Reflector, it confused me that Compiler DOESN'T generate a field matched with myProperty1. Why Is it a BUG？ Some codes as following: public class myCustomActivity: Activity { ... public myClass1 myProperty1 { get{...} set{...} } ... } pubic class myClass1: DependencyObject { public string Nam ...Show All

.NET Development Cannot assign to '<this>' because it is read-only
Hi, I have an DataManager class that is able to return an object populated from the database based on the class type and primary key value. I am trying to use that class in the constructor so that a user can simply pass in the ID and have an object loaded for them. However, I cannot assign the object that my class return to the current class using the "this" keyword because it is readonly. I also looked into Pointers, but C# does not allow pointers to user defined classes. I know that I can assign individual property from the object return to the current class, but my preference is to avoid having all those extra lines of cod ...Show All
Software Development for Windows Vista Roles and WWF
I've read the articles that Microsoft have published about the new WWF. I saw only in the article by David Chappel a few words about this issue. In People 2 People Workflows one of the major concernes is how flexible is Role resolution and Role assignment works. Where can i get more info about how WWF is going to address this issue Roles can be associated with all activities that interact with users via events or messages. The specific out-of-box activities that support Roles are: EventSink Activity and WebReceive Activity Check out Lab 10 in the Hand-on Lab at: http://www.microsoft.com/downloads/details.aspx FamilyId=35238943-291F-4 ...Show All

Visual Basic Using my own DLL in a new VB.NET project
I have made a DLL in VB.NET (class library), and wanted to use this DLL in a new VB.NET project. (VS 2005) So i create a new project, and add a reference to the DLL. The problem is, that i can't acces the methods or members of my class. I switched to VB for a few weeks, and used to create my DLL's in C++, so that's why i don't know how to solve this one... The DLL only consists of a few simple classes (members, properties and some basic methods). Can anyone help me out here THX Kenny all the classes are declared public, so it's very strange the members and methods aren't accessible... ...Show All

.NET Development How to append xml files
Can anybody tell me that how to append xml files If you mean that you have a Xml document and you want to add some more nodes in it then first you have to read it and gets its Enumuration ( XmlTextReader or XmlNodeReader depends upon which parser you want to use for it). Then you have to locate where actually you want to add a new node. The problem with Xml document is that your end and start tages for whole document should be the same. For this reason you have to really crawl to locate where your new node should go. To add nodes you need XmlNode class. One more advice is "System.Xml.XPath" Name space could be more us ...Show All
Game Technologies: DirectX, XNA, XACT, etc. Moving character against moving world
Hello, I'm building my first D3D game, a clone of Lander (the user must land off on a specific portion of ground with a maximum speed set instead of crashing) I'm wondering what is the best way : 1. Make the land module center of the world, camera looking at it and moving the ground mesh 2. lock the position of the ground and move both land module and camera accoring the user input. What are pros and cons about these two manners What about other games I'll build a day Thanks in advance. Steve Thanks all for your answers. I start thinking it depends on the game. As a beginner, I'm building a simple "Lander" ...Show All

Visual Basic Starting phase 2, need some advice
Greetings, I am a relative beginner with programming (took a class six years ago, don’t remember much), and I am delving into a “file managing” program for my family’s business. Today I finished phase 1 (of 3). Before I get started on phase 2, I could use some advice. In our business, we receive files (from our clients), each in their own distinct folder, uploaded to our FTP server, located in our office. Each client has their own (password protected) space on the server, and they could upload most any time of the day or night. Phase 2 of my programming venture is to have my software “sweep” each clients designated f ...Show All
