• Game Technologies: DirectX, XNA, XACT, etc. Vector maths methods...

  Following a long day of writing and debugging some nasty rigid body physics code, and feeling the pain of the maths library I have to use for this C++ work, I thought I'd take another look at the XNA maths code to see if the results would be more readable (as you might hope ;). ... But my quick look at the framework docs seems to show more deficiencies than in the code I have been using all day... 1/ There is no Point3 class. This is a real pain as libraries that don't distinguish points and vectors are a right pain - transforming a point by a 4x4 matrix will result in a different result to transforming a vector. (And I don't want to resort to coding every point/vector as a homogeneous coordinate either!). There appears to be a ...Show All

• Visual Studio Express Editions Asynchronous Calls

  hello fellow programmers, i was just having some problems on how to make an asynchronous call. well, can someone show me a very simple program thats uses asynchronous calls thanks in advance! I don't really consider delegates to be asynchonous in the sense I'm talking about. Yes, a timer event is asynchonous but what I'm really talking about is asynchronous I/O. Delegates are about multithreading, another aspect of asynch, but they are not true asynch communications. ...Show All

• Visual Studio Express Editions geting numeric data in and out of text boxes

  Hello, Summary: How do I set up text boxes so that when I enter numeric text in one box (named X_Test_Input) , it will raise events that the other box (named X_Accel_Raw_Value) will collect/consume and display the data in that second box. Overview: This is my first attempt Windows programming. My goal is to collect six numbers from an embedded device over Ethernet (five to ten times a second) and display them on my computer so as to have them available for further processing. In dividing this into small steps, I first want to be able to get values from somewhere and display that data. Only after I get the basic windows display part of this working will I attempt to get the data from the embedded device. In my ...Show All

• Windows Forms Referencing New Row

  Hi all, I am having difficulty referencing a new row created like this: Me .BindingContext(dtaSet.Load).AddNew() I have controls bound to a dataset that works just fine. The problem I am having is that I need to insert data into one of the rows like this: dtaSet.Load( Me .BindingContext(dtaSet.Load).Position ).lc_CustID = dtaSet.Customer(cboCustomer.SelectedIndex).c_ID When I try run this code I get an exception saying that there is no row at position 0 I understand it's because me calling the AddNew creates the row but it doesn't actually exist in the dataset yet. All I need to know is how would I reference the newly created row so I can insert data into it. Any help would be most appreciated. Regards Eric ...Show All

• Visual Studio Team System Specify IFormatProvider...

  I am trying today, for the first time, to check a console C# project with FxCop. There is a rule that it is difficult to understand for me. It is the rule 95 (warning CA1305). For example I have the code : throw new FileNotFoundException(String.Format("The file specified {0} does not exists!", bitmapFileName)) and it complains: makes a call to System.String.Format(System.String,System.Object) that does not explicitly provide an IFormatProvider. This should be replaced with a call to System.String.Format(System.IFormatProvider,System.String,System.Object[]). how do you manage this problem Do you specify always the CultureInfo every time that you have to provide a feedback message thanks for ...Show All

• Visual Studio Increasing the wait timeout for the VSS2005 Internet Web Service and IDE plug in

  Is there any way to adjust the time out parameters on the server and/or client side when using the Internet provider What's happening is that occassionally the connection between the developer and the server is a very slow one, and the plug in gives up (often at the worst of times), resulting in bindings getting confused. My client has also discovered that the server (Windows 2003) needs to be rebooted about once a week in order to keep the web service speed up. VSS2005 starts running slowly, they reboot the server, it speeds right up. VSS2005 is the only application hosted on the server at the moment. Thanks The timeout Barry talked about is set on the client machine, and affects how long will the client wait to receive the r ...Show All

• Visual Basic How to sign exe with digital certificate to suppress security warning from IE7 when executed from a client

  Hi newsgroup, I searched a lot in many newsgroups today, but now I'm very disappointed not to find an answer to my question. I know, that this is not a VB5 forum, but maybe my problem is useful for .NET users, too. I would appreciate, if you could point me to the right newsgroup, if this is not the right place. An old Server/Client software, developed with VB5 many years ago and still in use, is installed on a server and executed on some clients through a network share. Server and Clients run with every operating system Microsoft has released the last 10 years (Windows 95 to Windows 2003 Server). For many years this approach worked fine. But since the latest Updates from Microsoft for Windows XP SP2, especially IE7, a security war ...Show All
