• Visual C# Difference Between selectionchanged and selectionchangecommitted?

  What is the difference between selectionchanged and selectionchangecommitted in a combobox Hi, SelectionChangeCommited event is fired only when user changes the selected item (through UI), while SelectedIndexChanged and SelectedValueChanged can also be fired when currently displayed item is changed from code. Comes in handy when you need to track user changes only and ignore changes you're doing through code. Andrej ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Creating Effect Classes From Pipeline

  Hey, I have a BasicPaletteEffect, which is like basiceffect, except it also contains a matrix palette.  In my processor, if mesh has bone index and vertex weight channels, and if it doesn't already have an external reference to another effect, I want to set it's effect to an instance of BasicPaletteEffect (inside the content pipeline).  Is there any way I can do this Thanks. Thanks for the feedback.  I actually found that extending MaterialContent was better than extending EffectMaterialContent because I want to compile my effect from a string and not from an external reference.  Also, I replace the BasicMaterialContent with my own class after the base processor does the dirty work of c ...Show All

• .NET Development Resolution of DateTime.AddSeconds()

  The documentation says that the value parameter, which is a number of whole and fractional seconds, is rounded to the nearest tick (100 ns, or 0.0000001 s). However, my experience shows that it is rounded to the nearest millisecond. If you run the following code (C++ 2005, .Net 2.0): DateTime MyDT , NewDT ; __int64 diff ; MyDT = DateTime ( 2006 , 1 , 1 , 1 , 1 , 1 ); NewDT = MyDT . AddSeconds ( 0.1234567 ); diff = NewDT . Ticks - MyDT . Ticks ; Console :: WriteLine ( L "Difference #1: {0}" , diff ); you would see that effect. Is this a bug, a case of incorrect documentation,  or am I missing something Kamen I'm not sure where you are reading that at but the MSDN documentation (Aug 2006) ...Show All

• Visual C++ Compile C++ Code without a dependency on MSVCR80.dll

  I'm trying to write a C++ application that can run command-line without any help from Microsoft. Meaning no .Net installed at all and no Visual Studio installed at all and without dependencies on the Microsoft Visual C Runtime Libraries. The application that I wrote doesn't use anything outside of standard C++ so it shouldn't require anything and it compiles on Unix AS IS. Any help would be appreciated. 'As Is' is a bit misleading. The dependency on MSVCR80.dll is the Unix equivilent of being dependant on libc.so.*. The only difference is that in the Unix world everybody already has a libc installed, where in MS world, the C runtimes are not included and need to be installed. You should be able to avoid t ...Show All

• Visual Studio 2008 (Pre-release) WCF and Generics

  Hi all, I'm currently experimenting with using WCF and .NET generics together, in an attempt to have a service that exposes the following service contract: [ServiceContract] public interface IGenericServer { [OperationContract] void MakeRequest<IService>(); } Is this possible Upon trying my driver for this service the first time, I received a System.NotSupportedException--"Method MakeRequest is not supported on this proxy, this can happen if the method is not marked with OperationContractAttribute or if the interface type is not marked with ServiceContractAttribute." Has anyone else tried this with different results, or is this simply not supported in WCF Thanks! Well, ok. To ...Show All

• SQL Server Developer Edition Remote connection and related issues

  Hi All, I think I'm trying to do something I shouldn't but want to verify. I've got Visual Studio Pro 2005 Academic Edition with SQL Server Developer Edition. I loaded SS on my Windows Server 2003 PC server but am not able to connect remotely. I received help on another forum about how to connect the DevEdn but it doesn't read right. It appears that to do so, well, it even says, is a security risk. It just seems to me like Developer Edition was not made for remote connection. Is that true For any of you VB.NET/C# developers, is it hard to migrate a solution from a local solution to a network solution. That's what I'd do if I had to upgrade from a local version of SQL Server to a server PC based version of SS2K5. What is the ...Show All

• Visual Studio Express Editions Serial Port multithreading

  Is it possible for YourCOMPort.BytesToRead and YourCOMPort.DataReceived to change while the subroutine, which handles YourCOMPort.DataReceived is still in progress At very high data rates, the data may come in so fast that for example while previous data is being send to display by means of BeginInvoke new data are received. Depending on how Windows and .NET is build this may or may not course BytesToRead to change and/or a new DataReceived event, while the routine which handles this event is still in progress. If events are just boolean signals - not a queue - there may be a risk that if a new event occur while the subroutine, which handles this event is still in progress, the subroutine will not be reactivated (event cleared at exit). ...Show All

• Gadgets new XMLHttpRequest() - I'm at a loss

   I have programmed a gadget and it works great. I uploaded it to the Live Gallery and then I tested it and it doesn't work anymore. var xml_request = new XMLHttpRequest();  xml_request.open("GET", url, true);    <----- breaks here! the url variable is valid. It just stopped working all of a sudden with no code change. All the other gadgets in my sidebar can access the internet just fine. I have no idea why it just stopped working.

• Visual Studio Team System Sampling method of Performance Tool does not generate any report!?

  After successfully tried using Sampling method of Performance tool on a small console application, I applied the same skill on a larger WinForm application. But this time the tool does not generate any report under the Reports folder. Is there any limitation on the tool Or any special configuration needs to be set Hey John, I was just scrubbing the forums when I noticed that your question had not been answered. After collecting data with the profiler it should always generate a report or give you a warning that no data was collected in the profiling run. I've never seen an example of it not doing one or the other. One thing to check is that in the session property page for the performance session yo ...Show All
