• Windows Forms how to check for data change in a datagridview

  how can I check to see if a user has changed a cell in a datagridview well firstly, if you bind a dataset to a datagridview then the dataset will be updated automatically. you can see if the dataset has changes (theDataSet.HasChanges()) or you can get changes: Dim theChanges as new DataSet() = theDataSet.GetChanges()   this will return you the changes that the user has made in the first datatable I believe. does this help you you could also implement a CellBeginEdit event for the datagridview. This will fire when the user starts to edit that cell but I don't think it will fire when the user actually starts to change the cell contents but will fire when it gains "input" status (ready to ...Show All

• Visual Studio Use VC++ 2005 Express Edition to handle _debugbreak breakpoint

  Hi, I have VC++ 6.0 and VC++ 2005 Express Edition installed on the same computer. My computer is well configured to pop the VC++ 6.0 debugger when _debugbreak line is reached, but I need to do the same with VC++ 2005, does someone knows how to configure the registry (or something else) to get the VC++ 2005 debugger shows up instead of VC++ 6.0 debugger Thanks Thanks for the quick reply.

• Game Technologies: DirectX, XNA, XACT, etc. Can't stop a playing sound

  Hi, I play a sound using code taken from the well-known tutorial: public static void Play( string name) { Cue s = soundbank.GetCue(name); s.Play(); } I've got my own little routine for stopping the sound: public static void Stop ( string name) { Cue s = soundbank.GetCue(name); s.Stop( AudioStopOptions .Immediate ); } But the sound fails to stop. It doesn't throw any exceptions. Any clues Sorted. It seems you can't stop a sound from looking up the cue using GetCue - you have to use the original Cue you invoked the Play() command on. It seems the two are different! :D Anyway, I've just posted a demo game up on my site. *Blatent self publicity - turn away now!* I'm a ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Making Properties editable in the Properties Window

  Hello everyone, I created a new GameComponent which has a XNA.Framework.Rectangle as a property. I added one of these objects to my Game instance, but can't edit the Rectangle property (it is grayed out). How can I write a property (or class) in a way that would make it editable in the Property Window One solution I found was to make a number of Int properties that redirect to be member variables of the Rectangle. This is a bit clunky, though. I would like to be able to expand and edit the Rectangle property instead. It is not specifically Rectangle that I am interested in, as I would also like to make classes that I have created be able to be edited as properties as well. Does anyone know how I can do this Are there any tutorials out the ...Show All

• Visual Studio Feature request: Referencing Code Samples

  I often add example-code to the code comments showing how to use a certain function. The problem is that if I refactor the code, the example will be incorrect and there is no way of checking the example code with the compiler. Usually what I do is creating a bunch of methods that uses the functionalities and copy/paste that over into the summaries. This is a pretty stupid way of doing it though (because of the human factor involved). So this is what I propose: 1. Create a code sample file that compiles, and has parts of the code marked by regions: public void Example1() { #region Example1 myObject = new myObject (); myObject.Invoke(); #endregion } 2. Reference the region in the code summary: /// <example>Create a ...Show All

• Visual C++ VS2k3 -> VS2k5: Preprocessor definition being ignored?

  Hey everyone. I'm having a very...awkward issue with preprocessor macros: One of them is being completely ignored. I have a project that I've upgraded recently from vs2003 to vs2005. Within the project settings of this file, I've added the preprocessor definition REQUIRE_IOSTREAM. So, as should be expected, my command line output includes a "/D REQUIRE_IOSTREAM" argument. Then, within some of my headers, you then see expressions like: [code] #ifdef REQUIRE_IOSTREAM ... #endif [/code] So, pretty basic stuff. But the weird thing is, when I go to compile, VS never sees that REQUIRE_IOSTREAM has been set. So, if I were to throw a "#pragma message("calling the block for 'ifdef require_iostream'" line in there, I'd get nothin ...Show All

• Software Development for Windows Vista problems with graphics and sleep mode

  Ill start with the graphics problem I'm running RC1 on my laptop (IBM Thinkpad R31) and everything is compatible. The problem is that i cannot get my graphics card initialized. It installs the driver but it tells me that i can't turn it on. It doesn't make sense to me The graphics controller is the Intel 82830M. Like i said it will install the driver but it won't activate it. The other problem is that my Sleep mode is unavailable. Being a laptop i need either sleep mode or hibernate....and i dont have it. im afraid these forums are for software development and not technical support for Vista therefore I have to ask you to post your question to the appropriate communities: www.microsoft.com/commu ...Show All

• Visual C++ C++/CLI /CLR Managed Support in Native Library

  Hi, I have a C++ project, a .dll project in Visual Studio 2005, which uses all native C++. I was able to compile the project with the /clr option (just /clr for common language runtime support). I am able to add the a reference to the dll with another C++ project, which is also compiled with the /clr option, and the entire application runs fine. The problem comes when I try adding the .dll project reference to a test C# project and add a "using MyCPPNamespace" to my C# class. I don't see the new C++ project namespace anywhere within my intellisense in the C Sharp project and I can't just add it as a using. I thought compiling my native C++ project with the /clr option allowed us to add references to these projects in other manage ...Show All
