• .NET Development Threadpool Issue with WaitHandle.WaitAll FatalExecutionEngineError

  I have a process that goes out to each machine on the network and executes a few WMI calls. In the case that there is an error it takes about 5 seconds before it continues forward. 5 Seconds X 3000 Computers is more time that I have available. So, I have been messing around with ThreadPools. My thought is that I will kick off the WMI calls for 10 different machines then wait for them all to return. This way it only takes 5 seconds for each group of 10 machines. I have been using the Fibonacci Example to come up with the test code below but on my WaitHandle.WaitAll I am getting a FatalExecutionEngineError: Error: FatalExecutionEngineError was detected Message: The runtime has encountered a fatal error.

• .NET Development How do I set mouse cursor across applications (globally)

  I need to set the mouse cursor until a certain method is complete. The cursor should be the same for the whole OS, ie: even if the user hovers over other windows. SetCursor API doesn't seem to be doing anything. Thanks ahmedilyas wrote: to select a window an application Window if you want to select an application Window and active it, use the FindWindow and SetForegroundWindow API's: http://www.pinvoke.net/default.aspx/user32/SetForegroundWindow.html http://www.pinvoke.net/default.aspx/user32/FindWindow.html Yeah sorry maybe I failed to mention that I have managed to get the app working 100%, except that I thought it would be better looking if it had a cursor to select the window with.

• Visual FoxPro About the median of a grouped frequency distribution

  hi, I have a urgert problem about the median to be solved. I have the table like this age_group frequency cumulative frequency 1 18 18 2 24 42 3 39 81 4 23 104 5 12 116 6 8 124 What program code should I write to get the median Thanks. Let's see. The first thing that comes to mind would be an easy solution using XBASE code. Maybe not the most elegant but it should work. First index on cumulative frequency, then seek using NEAR ON which if it does not find, sends you to the next value instead of EOF(). Then if not at EOF() check to see ...Show All

• Windows Search Technologies WDS 3.x keyboard shortcut

  The default keyboard shortcut to search for anything in WDS 3.X is Windows key - Shift-F Is it possible to customize this I can't see anything in the options. You can define additional shortcut keys by going to the WDS link (visual shortcut) and right click and select properties. Go to the shortcut property tab and there is a shortcut key value. There you can add a new shortcut key. cheers, Ed ...Show All

• .NET Development Server connection timeout

  Hi guys, I am using the code below to connect to a server. This works fine on all the machines I have ever tried to connect to but a new server has recently been added on which it seems to timeout randomly. It would normally take 8secs to connect & retrieve information from a server but this takes 2 minutes on those random occasions. I believe that it may be the server timing out & responding a bit late as it might be busy or something.How could I possibly work around this and find out what is wrong I am using a third party SSH library to connect. I would appreciate any help StringBuilder output = new StringBuilder(); //SSH connection from 3rd party library (SSH2) //SSH Reader from 3rd party Socket s = new ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Quaternion Multiplication is Broken

  I believe that quaternion multiplication is broken. While you write matrix multiplications (to happen in order) as A * B, you have to write quaternions the other way around, qB * qA. I was chasing a "bug" in my animation code for the longest time before I found this! Here is a code sample that clearly shows the bug: class Tester { public Tester() { Matrix m1 = Matrix.CreateFromAxisAngle(new Vector3(1, 0, 0), (float)(Math.PI / 3)); Matrix m2 = Matrix.CreateFromAxisAngle(new Vector3(0, 0, 1), (float)(Math.PI / 3)); Matrix m3 = m1 * m2; Quaternion q1 = Quaternion.CreateFromAxisAngle(new Vector3(1, 0, 0), (float)(Math.PI / 3)); Quaternion q2 = Quaternion.CreateFr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Cannot get a list of Lobby aware applications (C#)

     Good evening all, I just cannot seem to get a list of Lobby aware applications registered on my system. I know there are two games that are listed on dxdiag's Network tab, and shown as Lobbyable applications. But when I execute: Microsoft.DirectX.DirectPlay.Lobby.Client.GetLocalPrograms() and try to attach to a listbox, nothing happens. The array is empty. Any idea why I have DX9 installed. Is it backward compatibily issue or something I'm missing Regards, Shuhrat There are few DirectPlay experts life out there so you might not get much help. Plus DirectPlay is no longer supported so you can't even get official support. One thing you could try is to get an old SDK that had s ...Show All

• SQL Server [SSIS] : STDEV in Derived Columns

• Visual C# Calling C# DLL from a Java application (or even another C++ or VB app)

  I have a C# DLL that needs to be called from a Java application. I suspect that this can't be done directly, but perhaps through a JNI wrapper to a C++ DLL which in turn calls the C# DLL I am looking for an answer that provides the simplest of examples that I can compile and test. (e.g. a C# class with a simple method that inputs one string and returns another....and those inputs and outputs are passed down and up through the layers).
