• Game Technologies: DirectX, XNA, XACT, etc. XNA 2D Collision Detection using Quadtrees

  I've seen a few posts on collision detection, and though I'd post an article on how to write a collision detection engine for your game. Take a look at: http://mbebenita.blogspot.com/ I'll follow it up with some source code as soon as I get a chance. Michael B.   MilliBong wrote: Hi, I read through your article, I liked the idea im just wondering how it would deal with having more than two objects that occupy exactly the same space Thanks! Jon In fact, the simpler case is just having several objects that overlap in any way.  You'd need to have some bailout logic to handle this sort of situation.  More than likely, if you try to subdivide a sect ...Show All

• Software Development for Windows Vista [Win32/Qos] Prioritizing empty TCP ACKs with Traffic Control API

  Hi! Surfing the internet I encountered an interessting read at http://www.benzedrine.cx/ackpri.html . Now I'm trying to accomplish the same thing under Windows using it's Traffic Control API. Problem is I don't know how to correctly set up my patterns in the TC_GEN_PATTERN structure. The only ones which come with the SDK are IP_PATTERN and IPX_PATTERN , and IP_PATTERN is declared as: typedef struct _IP_PATTERN { ULONG Reserved1; ULONG Reserved2; ULONG SrcAddr; ULONG DstAddr; union { struct { USHORT s_srcport,s_dstport; } S_un_ports; struct { UCHAR s_type,s_code; USHORT filler; } S_un_icmp; ULONG S_Spi; } S_un; UCHAR ProtocolId; UCHAR Reserved3[3]; } IP_PATTERN, *PIP_PATTERN; Now, according to the TCP ...Show All

• Software Development for Windows Vista can an activex be elevated(not an executable)?

  Hi, Thanks to Chris, I was able to elevate an executable file and call it from my test activeX. Now that I've tested this procedure works(activeX calling ShellExecute), I'm trying to apply the same procedure to our win-xp application. Our website runs an activeX with some arguments. Our activeX performs some admin-required actions(write on program files and registry). Then, it executes another executable. I am still thinking how to perform the same work on vista. Easiest solution would be our website runs a dummy activeX with arguments, the dummy activeX calls our original ActiveX(also has to be elevated), the 2nd activeX runs the final executable. In other words, I would prefer the above solution because it's the simplest. If that doesn't ...Show All

• Visual Studio Tools for Office ThisApplication_Startup not being called - ie. plugin not loading

    I have written an outlook plugin using VSTO. The plugin loads fine and works great if the user clicks on the outlook icon. On the other hand, if outlook is started via automation and then outlook is opened, the plugin does not load. These cases are described below. When the user signs on to windows xp with activesync set to run on startup. ActiveSync syncs with outlook by starting it through, AFAIK, automation. Now when the user opens Outlook by clicking on the outlook icon,  the plugin is not loaded. Another example is when the user has Outlook closed and they click on an oft file on their desktop, and then open Outlook, the plugin is not loaded. Please advise. Thanks. ...Show All

• SQL Server SQl 2005 Setup failure for cluster

  Installing SQl2005 into on Win2003 2 node cluster, at the very end of the setup receive a message 'Remote Setup failed'.

• Visual Studio Team System TFS Migration to a new server

  Has anyone been successful in migrating a TFS server to a new machine with a new name We are currently still using the RC, but I was surprised at some of the problems I had during a migration. Specifically Sharepoint, I don't know if its been improved with the RTM, but the restore procedures I saw were just wrong. The 1st trial I did had Sharepoint completely messed up. I finally fixed it, but it took my own understanding of Sharepoint, not the backup\restore procedures provided on msdn. Has anyone else had these issues I'm sorry about the delay in getting back to you, job change sort of had me preoccupied. Short answer, no you can fix it but its not all that nice. Long answer, uninstall TFS, delete the databases (make sure yo ...Show All

• .NET Development Invoke web services and SOAP

  Hi ... I have a general question about web services in dot NET : Is SOAP responsible for invoking web services If not , could someone please refer a tutorial or url on how is a web service invoked Thank you Evrim Evrim, Yes and No, Actually SOAP is just a protocol that defines the contracts under how a client and a server communicates using XML messages. However you may think that SOAP is responsible for invoking web services as web services responds to a SOAP call with an XML response. You can think this just like web pages.... in where the web server will respond to a HTTP call with an HTML.... in this case, you also perform an HTTP call to the server but you also send a S ...Show All

• Windows Forms Detecting word wrapping in a rich text box?

  Is there a programmatic way to detect where a RichTextBox control is wrapping the text contained within it I'm currently attempting to use TextRendered to measure the text and then determine that wraps occur the accummulated length would be at the box's width. This works for 98% of the words, but occassionally, my rpedicted model will wrap a word or two early. A fudge factor on the width seems to fix it, but for the final release, I would like the list of wrap points to be perfect. katesune You can use the .NET 2.0 GetFirstCharIndexFromLine() method to find out where each line starts. Which will tell you too where the text got wrapped. ...Show All
