• Game Technologies: DirectX, XNA, XACT, etc. XNA - Microsoft lack of vision

  Its real sad that Microsoft, once again, shows this lack of vision for a games development tool: 1: Get visual: Don't force users to write such a lot of code to do just very little. It reminds the Charles Petzold's "Hello Window" hell of code days. 2: Provide visual tools: Let users choose the components, change their properties and write just the required code for the events. 3: Quick development means quick prototype and minimum learning curve. XNA has a lot of things to learn. Definetively it is NOT for students and hobbists. We will have to wait until someone encapsulates XNA framework into a group of visual components, that can be easily drag & dropped, inspected and tested very easily without having to learn lots of n ...Show All

• .NET Development Problem Making Requests to a non-.NET Web Service

  I'm attempting to utilize a web service written in something other than .NET. (Not sure what it is... probably J2EE.) I grabbed the WSDL via VS.NET (I'm using .NET 2.0, btw) and it created the proxy classes. When I make the request the remote server just returns an empty request body. After poking around a bit I discovered that their example SOAP request and my actual SOAP request differed quite a bit. First, their namespace prefix differed from mine. Their's is SOAP-ENV and mine is of course just SOAP. I assume that's fine. But then it gets more strange. The particular method I'm calling is called makePurchase. My SOAP request, however, looks like: <soap:Envelope ...> <soap:Body> <Purchase> Their example SOAP req ...Show All

• Visual Basic saving an Excel Worksheet via Visual Basic 2005 automation

  Hi all, hopefully someone can help with this question, I've searched some forums but not found an instance of it. I've successfully opened an excel workbook via automation from a VB2005 application. The application populates the cells with data as it is received by the application. I want to use the Excel workbook to store data so that I can in the future access that information (weather data) and display it in Graphs etc or read the data into another application. The problem I'm having is that when I close the application I can't save the workbook, however I can trigger the save dialog box and do it that way but the whole point of the application is to run unattainded and collect and store the information. Here is the code I've trie ...Show All

• Windows Forms Encrypt app.config settings

  I've been looking at encrypting settings in my app.config file and have come accross this article on codeproject http://www.codeproject.com/csharp/ProtectedConfigWinApps.asp , it's quite useful but it only seems to apply to MSI installs. What I would like to know is is it possibile to add an installer class to a clickonce deployed application and get it to run. I don't know about this because I don't know how to tell the ClickOnce installer to run a specified installer class. If anyone has any other methods that I can use to encrypt settings in a config file or has some code I can use then please feel free to show me :) Thanks Jon ...Show All

• SQL Server Performance is degraded drastically after migrating to SQL Express 2005 from MSDE 2000

  Hi, Recently we have migrated our application from MSDE 2000 to SQL Server Express 2005(SP 1). This has significantly reduced the performance of our Windows.NET application which is developed using C#. For example : While logging in to the application two databases are being attached. Time taken in MSDE: 16 secs Time taken in SQL Server Express 2005 : 58 secs Also note performance is degraded for normal screens where data is retrived from database using inline queries. Questions: 1) Is there any special(optimum) configuration(installation parameters) while installing the SQL Server Express 2005 setup 2) Is there any query optimization to be done w.r.t SQL Server ...Show All

• SQL Server Telco Cube

  I am building a cube for a telco company. There is among others a subscriber dimension and a handset dimension. There is also a dimension to indicate a handset switch. In the source table, this is a flag set to 1 in the month where the switch occurs. I have added this as a measure to count the handset switches and also as a dimension. Other measures are a count of the subscribers and their revenue. I have added a calculated measure to know the average revenue per user. Now I would like to add a measure to know the average revenue before a handset switch and after a handset switch. Is there a way to calculate the average revenue for all months until the handset switch measure has a value and to calculate the average revenue for all month ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Detecting a controller button press?

  I'm using the following code to toggle my grid on/off at runtime: if ( GamePad .GetState( PlayerIndex .One).Buttons.Y == ButtonState .Pressed) grid1.ShowGrid = !grid1.ShowGrid; But it's badly flawed, in that the Y button is "Pressed" every time the button is down (eg. if I hold it down for 1 second, it would toggle 60 times). How can I reliably find if a button was pressed (eg. it's initial down state), without having to keep track of Up/Down states for every button myself that is exactly what my InputManager does. It keeps a record of the last state, if the state has changed since last time it fires the appropriate input event handler ...Show All

• Windows Forms ComboBox Resize Oddity

  I've got a problem when my ComboBoxes get resized. If a ComboBox has items populated and the Text property matches the start of one of the items, any change in Width on the ComboBox will cause the Text to change to the full item. Example: private void btnShowBug_Click(object sender, EventArgs e) { comboBox1.Items.Add("Annapolis"); comboBox1.Text = "A"; comboBox1.Width = 100; Console.WriteLine(comboBox1.Text); // Prints "Annapolis" } If I change comboBox1's Text property to "B" before resizing, this doesn't happen. Is this a bug in the framework or am I doing something wrong well does the combobox contain items that begin with "B" From what I can ...Show All
