• Software Development for Windows Vista man-in-the-browser attacks

  CardSpace seems secure once the user is in the CardSpace desktop, but I worry about the security of the application (IE, Firefox, etc.) that invokes CardSpace in the first place. How resistant is CardSpace and/or IE7 to man-in-the-browser attacks For example, a trojan browser helper object or extension that invisibly modifies the claims presented to CardSpace. The user is not likely to be checking the claims too carefully (if at all), and the Identifying Party of course has no way even to detect, much less prevent, this attack. Is IE7 hardened against such an attack, and if so, how CardSpace doesn’t just rely on the URL. It relies on the Certificate of the RP. Tokens produced by CardSpace are encrypt ...Show All

• .NET Development problems in Executing stored procedures in Asynchronous Request

  Hello everybody, I'm trying to launch a stored procedure from an asynchronous request but it doesn't wan't to start... The Sqlserver process goes crazy when calling the SP but nothing is written into the datatables... (I don't know what's going on at that moment. No exception can be thrown as calling manually the procedures with the same arguments works without any problems) This is the code i'm using to call the procedure: using ( SqlConnection oConn = new SqlConnection ( ConfigurationManager .AppSettings[ "MIS" ])) { oConn.Open(); using ( SqlCommand oCmd = new SqlCommand ()) { oCmd.Connection = oConn; oCmd.Parameters.Add( new SqlParameter ( "SqlQuery" , SQLquery.Selec ...Show All

• Gadgets How to Display and/or Host Licrosoft Gadgets for your Website

  I suggest that you download this instruction file in either Word or PDF as the images are not appearing via MSDN forum. Or dig into the code and d/l from the respective servers. Gadgets.pdf Gadgets.doc The simplest way to display any Microsoft Live.com gadget is to wrap it in an iframe on your webpage. I'll explain: First go to http://gallery.live.com and decide which gadget(s) you would like to display on your webpage. Of course it is also quite possible and highly recommended to write your own gadgets as well.

• SQL Server Clearing Single User Mode/lock

  What is the best way to clear Single User mode from SQL Server 2000 I have tried going to all tasks and selecting detach and clear Connections using this database. I then click cancel and go into the properties and options and clear the Restrict access check box. This seems to work some times but not all the times. I think it is because something else connects to it to it while I am going through the above steps. As a last resort I have detached the database and re-attach it. What is causing the single user mode to happen in the first place I am a little confused, the system is going into single user mode of its own accord and you want to get it back out again Have you looked at the error log to f ...Show All

  Hi there, I did upgrade of my VSTS server from Beta3 refresh to RTM. After upgrade I don't see my existing projects in list to add from 'Add Existing Projects' from Team Explorer. Upgrade went fine.Please help, Thanks, Anu, Apologies - when I said "restore" I meant "upgrade", i.e. running the TFSUpgradeRTM tool against your Beta 3 databases to get them ready for RTM.

• Game Technologies: DirectX, XNA, XACT, etc. user clip planes

  Hi all-- I posted this small question in the XNA framework forum, but got no response so I'm trying my luck here ;) I'm trying to add a clip plane to my scene, but this needs to be unprojected to world space first. This used to be done with the Plane.Transform method, which seems to be missing. Has anyone found a way to use clip planes in a 3D scene I could settle with a VS clipping all points on one side of a plane to their projected position on the plane, but this will give texture stretching artifacts, and simply feels bad. In the meantime, this post might be some help. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1003113&SiteID=1 ...Show All
