• Windows Forms Problem with List<T> and TypeConverter

  Hi, I am having a bit of difficulty with TypeConverters and Generic Lists and I was hoping that I could get a bit of advice. I have a type converter that is used to create the constructor code for my component. (It is an XNA a Game Component, but I don't think that that has anything to do with the problem because it appears on a Winform) inside another component. For instance I have the following: public class A{ private string s; public string SProp { get { s = value;} set { return s;} } public A() { s = "" ; } public A( string inS) { s = inS; } } By itself, when class A is an object on a form (or in my XNA Component) the TypeConverter code works fine, the property grid on t ...Show All

• Windows Live Developer Forums Bug in tile layers when switching styles

  Yes, I am moving onto tile layers and found that: 1. Go to the iSDK and goto "Use custom tile layers" - load one of these a wait for it to show up 2. change to aerial (or road if you were on aerial) 3. Click on the zoombar to zoom right out the tile layer is still over the screen! I thought i had it solved by deleting the layer and then adding it again but no luck. I have found no way to get rid of it. Any of you guys who have done lots of work with tile layer fixed this My code is basically the iSDK example running in both IE7 and FF2 (with fix).

• Visual C# Picking at random, with varied probabilities

  One part of a program that I'm writing requires me to pick an object at random out of a collection. Each object has a different weight (probability), currently stored as a Double, associated with it, and the number of objects varies. The total probability, 1.0, is equal to the sum of the weights of all the objects in the collection. Is there a commonly used, efficient algorithm for picking random objects in this situation Currently, the only one I can think of (and this is pretty tedious): Load the keys and weights of the collection's objects into structures inside an ArrayList. Sort the ArrayList in ascending order, by weight. Add on another value (CumulativeWeight) to each structure that represents the sum of all the weights up to and ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game and GameComponent Feedback

  We've been combing the forums and the Connect database for bugs, feedback and suggestions around the application model. We still have a small amount of time to consider any other feedback you may have. So this is the thread that you post your latest likes or dislikes with Game, GameComponent, services, etc. Please scan the other threads before posting here, I'd like to just gather things that haven't already been discussed or reported elsewhere. Thanks! I'm against the GameComponent stuff. I just don't see the point in this. This is high level logic, that is application dependent and surely don't have to be in the core libraries. I even don't see the point in adding my the graphics device to the game components... If we have ...Show All

• Visual Basic Program to execute on one machine only

  Hello, My problem is that I want to deploy my program onto a 'thumb drive' and sell it that way and I need the program to only run off that drive. It is a small program that can easily be copied and run by anyone so I thought that if I could somehow 'lock' it to the small USB drive then that would solve my problem. Because some games require a CD to be in a drive before they will run I figured that that would be something that I could do, my problem is finding any help in how that might be accomplished. Can anyone point me in the right direction Thank you very much Bill Langston Yes, I agree -ca, I just don't have the knowledge to figure it out. I feel that if we can find a solution and have it archived here for oth ...Show All

• SQL Server How to rename a table ?

  Hi all. I'm porting an application from eVB-ADOCE to VB.Net-SQL CE In the old application there are some SQL statements like this: "ALTER TABLE OldTable TO NewTable" Is there an equivalent instruction or a simple way to rename a table I was not able to find anything simple to do the same. I really need NOT to do something like SELECT * INTO NewTable FROM OldTable because the resulting table could go outside memory and/or spend too much time in elaboration. Please let me know what I can do. Many thanks ! As far as I know, there is no such option from SQL. But you can rename a table (and a table column) using OLE DB: QA: How do I rename a SQL CE table ...Show All

• SQL Server Forgive my "french" but...

  Exactly what does it take to get ReportBuilder for SQL Reporting Services to actually function. I had VS2003, then I installed VS2005 with SQL 2005. Everything installed to the best of my knowledge....How do I know....because the installation program was smart enough to sniff out SQL Report Services 2000, automatically rendering it unusable by giving the rsreportserverdisabled message due to the key encryption. After much searching I found an article to fix this ( http://codebetter.com/blogs/john.pappa/archive/2005/12/27/135963.aspx ) Now, report functions but no report builder. IF I CAN'T GET THIS TO FUNCTION by tomorrow...I will be forced NOT to recommend SQL Report Services for the next generation of software we ...Show All
