• SQL Server The IDMClusteringAlgorithm interface

  Good morning, Well... I'm implementing a clustering algorithm following the examples given on the Managed Plugin Algorithms tutorial. As the samples are in C# and I'm implementing it on C++, I'm facing some problems, but nothing really significant. But I've some conceptual questions about the implementation: 1) It necessary to implement the IDMClusteringAlgorithm interface in order to implement the ClusterMembership() and the CaseLikelihood() methods, right 2) The changes needed to be done on the Navigation class have nothing to do specifically with clustering. These changes are only to set calculated statistics to be shown, and if I want, I can simply don't implement them. Is this correct 3) Is there any documentation on ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. A Question (Creators Club)

  I was wondering this. Since I have a cable connection (no router) directly to my computer, how would I connect my Xbox to my computer so I can use the Creators Club Right now I just disconnect the Ethernet cable from the back of the cable modem and connect the Xbox 360 Ethernet cable to get Live on my 360. Billr17 wrote: Just a side note, its been mentioned that the transfer of XNA assemblies between the PC and 360 is unsupported because of slow transfer rates and the possibility of signal loss. Umm, I assume you meant "wireless transfer", not all transfers. heh. Do you have a link for that I can see that as a cover-your-behind-disclaimer for support reasons because so many things can go wrong in a wireless co ...Show All

• Windows Forms Bound datagridview failing to update

  Hi I'm trying to update a datagridview which is bound to a class within an event raised by a button click and I can't seem to get it to work. Initially I bind the datagridview to a class containing a list (of another small class). The grid sets up the headers ok, and I can add rows within the constructor and once it's constructed it works fine. The problem comes when I try to add rows programmatically on a button click. I'm updating the list the grid is bound to, and it would appear to work if you look at the grid in a watch in the debugger, however it doesn't update on screen at all. Then if you try to edit anything near the bottom of the datagridview it causes an exception. I'm clearly missing something basic in my understanding. Coul ...Show All

• Software Development for Windows Vista starting application from setup - not as administrator

  Hello all: When my application is run for the very first time at the end of the installation process, it is running as administrator, because the setup itself was automatically detected and elevated by Vista. Is there any option to run it from setup at usual (medium) privilege level I have tried manifest with requestedExecutionLevel of asInvoker - to no avail. TIA OTNS I'm kind of curious about this install-time service approach. If the user is a 'standard user,' runs the admin app (providing credentials for an admin user) does the service produce an app running as the original user Or the weak version of the admin Does it work correctly in an environment where there are multiple lo ...Show All

• Visual Basic need help with offsets for LayoutKind.Explicit - unravelling a returned struct from unmanaged into managed

  Mathew Gertz pointed me in the right direction I believe in an earlier post. My P/Invoke is returning valid values for 'name' below at field offset 0 and other values as I can see in QuickWatch. StructA below is passed and returned from the unmanaged C++ dll with valid values. An error is thrown however; System.ExecutionEngineException was unhandled   Message="Exception of type 'System.ExecutionEngineException' was thrown." I would like to try Mathew's idea of using LayoutKind.Explicit rather than LayoutKind.Sequential which I am currently using. If I had <FieldOffset(0)> for the first member of StructA, can anyone help me with how the rest would look I would say Offsets would increase by     1. 4 after each Integ ...Show All
