• Game Technologies: DirectX, XNA, XACT, etc. simple projectile motion physics??

  im pretty new to gamedev, so simulating physics is new to me too. i know the projectile motion formulas, im just having trouble applying them. is there any "tutorial" on projectile motion physics for XNA basically, someone suggested to do "scorched earth". im trying to get the hang of just some simple projectile before i apply it to a game. i know i should basically have to just enter the initial velocity vector and the angle. then have it passed to a function that gets the initial x velocity, and initial y velocity. also, im assuming that whatever i get for y-velocity should be negative as "up" is negative in the XNA graphics. then, after each update, it should find the current change in position for x and ...Show All

• SQL Server Table to Named Query in DSV via AMO

  Has anyone been able to change a table to a named query via AMO Ok, I tried the code and here's a version with some minor corrections so that it actually works: The following code needs to reference Microsoft.AnalysisServices.dll. using ( Server svr = new Server ()) { // Connect and get a table to convert svr.Connect( "localhost" ); Database db = svr.Databases[0]; DataSourceView dsv = db.DataSourceViews[0]; DataSet dataSet = dsv.Schema; DataTable table = dataSet.Tables[0]; // Convert table to named query table.ExtendedProperties[ "TableType" ] = "View" ; table.ExtendedProperties.Add( & ...Show All

• Windows Forms Create a Strong Name for Com DLL so ClickOnce will work

  I'm having a heck of a time tryin to get this stuff working. Here's my problem: We have a 2.0 VB.NET desktop app that uses Com components from our phone system. When you make references to the COM components for the project, they create the Interop.xxx.dll files in the project's bin folder. Well, I'd like to figure out how to get them into the GAC or how to some how make them strong named so that they'll work when I try to deploy them with ClickOnce. I've tried to use regfree com to deploy them and that doesn't work (I can provide the error if it will help). I've also tried to drop the Interop.XXX.dlls into the GAC and that won't work because they're not strongly named. Now, maybe if I could figure out how to name them strongly it would wo ...Show All

• Visual FoxPro Problem after upgrading to VFP9 from VFP7

  The following procedure works fine VFP7. When a second user tries to lock the IDFILE before the first one unlocks it he receives the message and the PROCEDURE returns. After upgrading to VFP9 the second user instead of the previous message he gets a message from VFP "An error has occurred: File is in use by another user. etc". He gets a similar message if he even tries to open for read the IDFILE while in VFP7 there was no such problem.

• Windows Forms Numeric Up Down control is buggy

  I find the NUD control to be quite buggy when conntecting it up to a data source; in VS 2003 it was useless (I had to manually handle all of the data binding / updates etc). In VS 2005, the data binding "seems" to work except that it will not "refresh" the displayed value when the data source value is changed. For example: create a binding source connected to an in memory data set; set value to 2.13 bind a text box and NUD control to a binding source. update the value in the dataset to 5.15 the value 5.15 is displayed in the text box ok the value 2.13 is still displayed in the NUD, but the actual value is now 5.15 ie: the NUD.value = 5.15 but the NUD.text = 2.13 when I click on the up/down arrows, the text *just* ...Show All

• Visual Studio Team System checking event raise method

  Basically I want to create a custom rule that checks that event raising method have the following structure (As you will see, we didn't see the point with the object sender, EventArgs e thing, so we decided to skip that...) protected void OnFoo( int foo, int bar) { FooEventHandler handler = Foo; if (handler != null ) { try { handler(foo, bar); } catch ( Exception e) { m_logger.Error( "Failed to do foo" , e); } } } For this, I figured that I'd override Check(Member member) cast to Method, then walk trough .Instructions Specific questions: - how do I know that the callvirt Invoke to handler(foo, bar) is in fact an event raising operation and not let' ...Show All

• SQL Server Custom Data Extension - Designer Extension Could Not Be Loaded

  Hi All, I've managed (finally) to get a Custom Data Extension to work in Reporting Services 2005. The next problem I have is that whenever I click on the "data" tab when creating a report (from Visual Studio 2005) an error appears: "The designer extension <ext name> could not be loaded. Check the configuration file RsReportDesigner.config". Is there some way of getting rid of this error message Such as creating a designer, if so does anyone know how (I don't need the designer to do anything, just not crash) I can still modify the data for the report etc its just annoying that's all.
