• Game Technologies: DirectX, XNA, XACT, etc. GameComponents controlling GameComponents

  Most XNA game examples I have seen so far load all the game components right away at the beginning of the game no matter what. I looking to setup a GameComponent (GameWorld) which the user will control to load which will subsequently load several other game entities which are inherited from the DrawableGameComponent as well, but they all controlled by the GameWorld as far as enabled/visible. This appears to work fine so far, I'm just curious though if there is anything wrong with this finite number of game entities all having there own SpriteBatch property because of this. Performance issue when GraphicsDevice is recreated Or even if this is a workable practice In other examples, I've seen certain drawable game entities custom created wh ...Show All

• SQL Server Time Series Periodicity

  I'm trying to learn about time series algorithm but I can't set the time periodicity right. I have information stored 2 times a year (semester) so I'll should set up a PERIODICITY_HINT = {2}, right but it does not change anything. Here is a screenshot that might help understand the problem: Based on what you have explained, there is no problem, it's just a behavior. Is the issue that you somehow require a (t-2) factor Or you simply believe there is an effect, so you want the algorithm to find one One possibility is to reduce the complexity_penalty or minimum_support parameters, which will change the size of the trees that the algorithm grows. Other than that, your data doesn't seem to support su ...Show All

• Visual Basic How to display a Unicode character

  Greetings: After an hour of futzing around, I still can't figure out how to display a unicode character. Encoding, decoding, whatever. Here is as far as I've gotten: Dim uni As New UnicodeEncoding() chkBf.Text = "B" & uni.GetDecoder(\u266B) which doesn't work at all. It can't be too complicated, but I can't make heads or tails out of the help files. I want to display the musical notation "flat" symbol. Thanks! Thanks, Bruno! Will that deliver me the symbols I'm after, even if the font doesn't support those particular Unicodes After poking around some, I'd come to the conclusion that the problem was in the font support of unicode. I could get other unico ...Show All

• Community Chat Free Online Visual Basic 2005 book

  I have recently made my book free, sponsored by AdSense of course. The book is designed for non-programmers. After many hours of tweaking javascript I have finally completed most of the design of the page, so that it works with google and also so that there are no frames. If anyone would like to help with the book, ie: make it better, then feel free to contact me here or at the site. You can find the book link in my signature...   robinjam wrote: C# and C++ are fairly similar, so there isn't really much point in putting both in the book.

• Smart Device Development Disconnecting GPRS

  Hello, After calling a web service and my device connects to gprs, I want to shutdown the gprs connection via code. Does anyone know how to do this Unfortunately .net compact framework does not offer the handle to the connection object up in managed code to developers. As a result, developers cannot explicitly close out the GPRS connection. If the network is not used however, the http implementation should shut down the GPRS connection after it has finished using the connection. Thanks, Sandy ...Show All

• Visual Basic Shared interface member

  Why can't interface methods be declared Shared in VB I have a controllerFactory interface that is used in a number of apps to dispense app sepcific controller classes for use in an app neutral framework. Currently I have to create an instance of the controller factory classes to invoke the GetController methods. Ideally I'd like to make this method shared and invoke it without creating an instance of the Factory. If I try to mark the implementation shared then Visual Studio shows the error "methods or events that implement interface members cannot be shared". If I mark the interface method as shared the error message is "'Shared' is not valid on an interface method declaration". Here's the interface definition: ...Show All

• Visual Basic Dts.Runtime errors

  When I use Imports Microsoft.SqlServer.Dts.Runtime in vb2005 previously working code starts generating errors. For example: MessageBox.Show( "Error: " & description) now generates this error: Error 1 Operator '&' is not defined for types 'String' and 'Microsoft.SqlServer.Dts.Runtime.DtsObject'. Application.Exit() generates this error: Error 2 'Exit' is not a member of 'Microsoft.SqlServer.Dts.Runtime.Application'.

• SQL Server Create Pull Subscription from client

  I am trying to create a pull subscription through RMO as described in books online. However, the only way that the creation (or deletion) will succeed is if the windows user that is creating the subscription is a member of the sysadmin role on the publisher. The windows login has been added to the PAL for the publication, but this seems to have no effect. The windows login has been added to the subscription database and is a member of the dbo role. Please help! Thanks! Can someone please respond to the original poster I am having the same problem and have tried the same approach.

• SQL Server How to query on a date range, display matching records but also display companies with no matching records?

  OK, hopefully someone can help me on this one. I have a report that allows a user to select a date range and returns the applicable data. Hypothetically, this returns to the user 3 rows of data for 3 different companies\sites. The problem is that the client wants to see the other 7 companies\sites that don't have data for the date range specified by the user, in the same report. I am having issues with this as my query returns the results that exist within the date range. If now rows of data exist for the date range, how can I possibly display the other 7 companies I looked at embedding a report inside of another report, but I can't think of a query I could write that says, if these companies are not in the result set generated by the ...Show All

• Visual C++ C++/CLI Types

  Hey All, When I was using Managed C++ back in the old days of VS03, I remember being very careful to use Int16 instead of short, and Strings instead of std::strings. I'm wondering how much of a difference that makes w/ the new CLI. Is "int" equivalent to "Int32" as far as garbage collection and such Also, I caught myself doing this today when I declare variables. String ^str; but when i do my arrays, I put the handle like this... array<String^>^ str; Where is the 'proper' place to put the cap Cool...thanks for the input. With C++/CLI, is it kosher to concat strings with the plus "+" sign, or is that frowned upon and String::Concat prefered ...Show All
