• Game Technologies: DirectX, XNA, XACT, etc. Mesh built at runtime?

  Is it possible to build a mesh at runtime I don't necessarily want to use the content pipeline to load anything. Suppose I want to randomly generate an arbitrarily sized terrain at runtime. The only way I can see of doing this now is to use a VertexBuffer. Is this correct or is there another way I've read the threads on using MSBuild to use the pipeline, but I don't want to go that route. If I wanted to access DirectX directly inside an XNA project, what is the best way to go about this Basically, is it safe to continue using MDX (from what I've read, it's not in the long term) or should I just use interop to directly access it Using vertex buffers is not only the "only" way, but also the &quo ...Show All

• Visual Studio Team System Why is TFS not available to Empower Program subscriptions?

  My beef is that TFS isn't available to anyone with an Empower Program subscription (except in prohibitively expensive editions). The TFS Workgroup Edition comes for free with Team Edition MSDN subscriptions, but it can't be bought separately. If it could, I would have bought it by now. To me, this makes very little sense. Source control/configuration management is very much a grassroots sell (i.e. it's a decision effectively made by programmers rather than by 'bigwigs'), and making TFS widely unavailable means far fewer people able to sing its praises to their peers. I work with several configuration management tools, and I'm able to engage in intelligent discussions with clients about CVS, per:Force, even good old SourceSafe, but ...Show All

• SQL Server Inconsistent Linked Server Query Results

  Hello, I have a linked server named 'Charlie_File' to an Excel Workbook that I set up in SQLServer 2005 Management Studio. The workbook is on my local C drive. Sometimes, I get the results back that I expect when I run the following query; SELECT * FROM OPENQUERY ( Charlie_file , 'SELECT * FROM [Feb$]' ) Sometimes, on subsequent runs of the above query, I get the following message; Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "MSDASQL" for linked server "Charlie_file" reported an error. The provider did not give any information about the error.

• Visual Studio Express Editions Numeric Only Values

  If in a Key_down event I want to ensure that the data that goes into the listbox is only numeric do I use a If then statement   I would like it so that if the user input alphanumerica data my program will show a message box say it must be numeric and then reset the textbox to empty and put my focus back on the text box   I tried the following code but I get the error message "must be numeric" even when the key pressed is numeric Private Sub TextBox1_KeyDown( ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown a = TextBox1.Text If Not IsNumeric(TextBox1.Text) Then MessageBox.Show( "Must be numeric value Text Box 1" ) TextBox1.Text = "" Te ...Show All

• Visual Basic Posing equations

  Hi I run into trouble when I wanted to test equations. Having an array of equations e.g. {"2X+3Y<=20","5Y+7X<10"....} I like to pick the equations out and test them like Dim X As Integer = 5 Dim Y As Integer = 7 Dim Eqation() As Integer = {"2X+3Y<=20","5Y+7X<10"....} if 2X+3Y<=20 and 5Y+7X<10 then ....

• Windows Forms datagrid column format date

  I need to format the output of a date field in a datagrid column to just show the "Year", nothing else. When I go to "Edit Column", "DefaultCellStyle", "format"... I get a list of Formatting Values and nothing in Date Time formatting has what I'm looking for......" Year"..... I guess I would need to use "Custom", but I"m not sure of the syntax to use in order to get just the centery, "2006". There are a couple of options here. One is to format the date in your SQL statement and the other would be to extract the year of the date using code. I don't know which DataGrid you are using (ASP.NET WinForm ) or database (SQL Server ...Show All

• Visual Studio How to correct "#Error" when report is rendered

  Hi, I'm working on a report using a dynamic table as in the example on gotreportviewer.com. The dataSource is a generic list of business objects. Each biz object may be an instance of one of three classes, (say : ChildClassA, ChildClassB, ChildClassC) all inheriting from a common base class. All the properties to be diplayed are in the base class, but some are overriden in the base classes. When the report renders fine, except that I get a lot of property values not being displayed. The string "#Error" is displayed instead. Interestingly, it seems to depend on the order in which the classes appear in the list. Say my dataSource starts with an instance of ChildClassA. Then each line of my table displays the value of ChildClassA.So ...Show All

• Commerce Server CS 2007 Site Configuration

  Hi All, I am a beginner and learner in CS 2007. I have a task of configuring a website in CS 2007 and going live with it. The existing site has been developed and configured using the following: PHP, MySQL, Joomla (freeware Content Management System) and VirtueMart (Open Source E-Commerce solution to be used together with Joomla, Content Management System).

• Visual Basic diplaying bitmap from access database

  I've seen this question posted a few times but no good results. I'm simply loading a dataset from access that happens to have a bitmap stored in a field. I have a listview with a list of CD's by Album/Artist, when I click on one of the CD's I want detailed info to populate below, including a pic box with the stored bitmap. Everything works fine except the pic box.
