• Smart Device Development time function

  Hi, I'm new to C++ and I am writing a project in it that I want to build on both Windows CE and VxWorks, so I am compiling the project in both MS Visual Studio and Wind River Workbench. There are a number of places in the app where I want to get the current date and time (number of seconds since 1/1/1970) but I can't figure out how to make it work! From what I can tell, time(time_t * timer) is the way to go, but while this compiles fine for VxWorks, when I compile it for Windows I get a strange linker error which says that there are unresolved externals in the function that contains the call to time(). Help! (Thanks in advance!) Rachel I wasn't trying to be rude at all, I was just asking--I do ap ...Show All

• .NET Development How do I know what framework I need?

  I have Windows XP Windows Media Center and .NET Framework 1.1 Configuration (version 1.1.4322.573). I see downloads for 2.0, 3.0. Do I need these and how do I know well you dont need them unless some software requires it. you can stick with the one you have, its actually bundled into the SP2 I believe of Windows XP (all versions) you can always stick with the latest and greatest have .NET 3.0 is still not fully complete, so you can use .NET 2.0 if you like. If you are developing applications in VS.NET then the appropriate .NET Framework will be installed however you are more or less stuck with the .NET Framework version to develop in by VS.NET VS.NET 2002 -> .NET 1.0 VS.NET 2003 -&g ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is XNA the tool for serious game developers.

  I'm trying to make the decision if our game development team should use XNA as the technology solution. The question is, if XNA is capabale, or is intended to be, a commercial game development tool set for serious game developers. Dave van Bale wrote: ... you cannot develop as easily as you can with C++/DirectX for alternative next-gen platforms (Macintosh (hah, as if), Wii or PS3). Well, to be fair, you cannot develop for alternative platforms with c++/ DirectX anyways I, however, haven't seen many remarks on the possibility to opening this to other platforms. http://www.taoframework.com/Mono.Xna ...Show All

• Visual Studio 2008 (Pre-release) ToDataTable() and null values

  //Create DataSet DataSet someset = new DataSet (); //Fill DataSet DataClassFillSet(someset); //QueryDataSet var q = from o in someset. Customer select new { o.CustomerID, o.NullSometimes }; //Make data table out of our query. DataTable atable = q.ToDataTable();   The NullSometimes throws an exception when the value in the column is null, how does one avoid this I think the problem is that this is a strongly typed dataset and the null value is being cast to a type, which fails. How can I tell linq to check nulls Hello, The design of the Typed DataSet is such that if you attempt to get a null value (that is, a value of DBNull.Value), an exception is thrown.

• .NET Development Is Windows Communication Foundation something for me?

  I'm pretty new to both .NET remoting and Web services. However, I'll soon be involved in a project using components on remote machines that'll need to comunicate over the internet. So far I'v been looking at .NET remoting 2.0 and Web Services. But what about WCF Is .NET framework 3.0 finally released for Windows XP Will it be supported on Windows 2000 (I think I read it's not ). Would it be foolish by me to start a new project today using .NET remoting (2.0) or web services (instead of WCF) The app will be entierly in a Microsoft environment, so I will not need platform independency. Pretty large amounts of data will be transformed between the hosts. Any information (mainly considering .NET remoting vs WCF) is much appreciated! r ...Show All

• Visual Studio 2008 (Pre-release) Focus() does not always appear to work for me ...

  I've got a window created in XAML, and it's got a couple of TextBoxes on it. They are both focusable. Before I display this window using ShowDialog(), I set the focus to one of the TextBox controls. The first time the window is displayed, this works fine. But if the other TextBox gets focus, then it doesn't seem to relinquish it - the next time the window is displayed, the second TextBox has focus, even though I am specifically trying to set the focus to the first TextBox in code. I don't know if this matters, but I'm not destroying the window in between the times it is showed. I simply call the Hide() method to hide the window. Then before I show the window the next time, I attempt to set focus to the correct TextBox. I've stepped thro ...Show All

• .NET Development Element restriction question?

• Visual FoxPro pass contents to C#

  hi! this is sort of connected to my other post regarding Foxpro and C#.. in the foxpro program i will type in a name and when i call the C# program it will also contain the name entered in the foxpro program. is this possible How can i do this thanks! From C#, you use ADO.NET, connect to the database that contains the data and query it. There is nothing to it, and it is not related to VFP. A SQL Server database is a repository of data. Which client you use to access that data is immaterial to SQL Server. So it is perfectly OK to insert data from a VFP front-end and retrieve it from C# as you want to do. If you are unfamiliar with C# and ADO.NET, there are forums here for them where you can ...Show All

• Visual Studio MSDN Installation

  This question is about installing the MSDN library that came packaged with Visual Studio .NET 2003 Academic Edition. I know this forum is labeled for 2005, but I didn't see one for 2003. Hopefully, this is still appropriate. The problem I am having is that after installing the MSDN library, I can't access any of the information in it. All the filter lists on search, index, contents, and dynamic help are empty, and all the results windows are empty, regardless of what I type. If I try to use search option, it just says "Unspecified Error". Does anyone know why such a thing might occur I've tried searching for help on the internet and these forum. But "unspecified error" is too ambiguous to get any help that relates to my ...Show All

• Visual Studio 2008 (Pre-release) possible 3D rendering problem

  got a 3D scene with multiple objects in it. some of those objects are 2 blocks. another object is a window with a transparent texture. but the problem is the window will see-through some of those blocks. e.g. if i look through the window to look at a block, then i can't see the block. if i don't look through the window, then i see the block. even stranger, is that the order in which the objects are added to the scene matters. if i add block A, then the window, and then block B ... then looking through the window, i can see block A, but not block B. if i add both blocks before the window, then i see both blocks. if i add both blocks after the window, then i can see neither through the window. any ideas what is happening here NOTE i ...Show All
