databinding over remoting nonick225-Apr-05 21:57 nonick2 25-Apr-05 21:57  hello. i am trying to creat a server/clients application and i want the server to hold an object and the clients to recive references to that object. (so far easy) but i also want to do databinding on some of the propertyes so when someone changes a property the other clients will see the change live... i tryed treating the remote object as an ordnary object and creat databinding but it didnt work.. is it even posible? can any one here give me an example of how to do it? Re: databinding over remoting MBGeorge4-May-05 21:50 MBGeorge 4-May-05 21:50  Try using one event so the other clients know that they need to refresh their data. I don't think u have a refference to the data, but u have a ref to the object, so the properties of ur client ref object will change when u call them again, not when some other client set them .You still have to deal with concurency. I hope u undestand, my english is bad. Need source code edit control Video Game Ministry25-Apr-05 11:37 Video Game Ministry 25-Apr-05 11:37  I really need a 'C++ source code' edit .NET control. XSD.exe Fabian Goncalves23-Apr-05 12:12 Fabian Goncalves 23-Apr-05 12:12  I hope that someone already stumbled with this. I'm starting a new Interop project having Java webservices and a .Net invocation manager for this services. All our DTOs (Data Transfer Objects) are specified as XSD files, and we generate our serializable objects from there. Now, I was able to generate classes from the schemas, but I have a problem with the properties, I cannot generate the properties with setters/getters wrapping around private fields. Is there a way to achieve this using the xsd.exe shipped with VS? Is there any other tool to do it? Thx... Fabian Router External IP address resolution... Chris Quick23-Apr-05 5:45 Chris Quick 23-Apr-05 5:45  Are there any good articles or resources available for resolving the external IP address of a router from an internal computer. I have a computer that is using 192.168.0.x and I want to know the external IP address of the router that is located on the same network. I have looked at the System.Net namespace, and it appears to have a very limited functionality for IP address querying, unless I'm missing something. Thanks in advance!

Peter Ritchie24-Apr-05 8:58 Peter Ritchie 24-Apr-05 8:58  Unless your router has a specific means of requesting that information (I know of none that do) you have to go outside the WAN and come back in. There's several sites out that perform this like http://www.talkswitch.com/wap/checkip.php[^], http://www.historians.org/HistoryCoop/IPCheck.cfm[^] or http://ip.discoveryvip.com/[^] PeterRitchie.com Setting Style (SetStlye Method) With API THEMYTH23-Apr-05 1:45 THEMYTH 23-Apr-05 1:45  Hi coders, I was wondering about the apis used while writing the SetStyle Method. I am creating an API control class using NativeWindow class in .net framework. I need to set styles of the window (like double buffer, userpaint, resize redraw...) Some of these styles can be applied by using SET... apis (like instead of SetStyle Opaque, True ; SetBkMode api can be used) I need to know the apis used for all other styles in ControlStyles enum. Thank you for your time Best Regards Emre YAZICI Re: Setting Style (SetStlye Method) With API Peter Ritchie24-Apr-05 9:08 Peter Ritchie 24-Apr-05 9:08  The ControlSetStyle method *is* used to set the ControlStyles bits. Or, are you talking about a different API other than .NET? PeterRitchie.com Re: Setting Style (SetStlye Method) With API THEMYTH24-Apr-05 20:15 THEMYTH 24-Apr-05 20:15  Thank you for your answer. I know what the ControlStyle bits, and I know what is it doing, the reason why i am asking for a way to perform the SAME thing(as SetStyle does) I think we are able to set the styles with API e.g (As I mentioned) Instead of SetStyle (opaque,true) you can use the SetBkmode API, and (I am not sure) instead of Double buffer, you can use CreateCompatibleDC API. I am asking for the other ones' apis. Do you know them? Thanks Best Regards Emre YAZICI Re: Setting Style (SetStlye Method) With API Peter Ritchie25-Apr-05 3:21 Peter Ritchie 25-Apr-05 3:21  Okay, you've misused the work API--which is an interface (or a group of functions/methods). You're looking for all the methods that perform the same thing as SetStyle for each bit... There normally isn't a one-to-one correspondance with a style bit and a method or a function. Many of the styles shouldn't be changed after the window has been created, they're ment to be used as the window is being created where calling a dozen or so methods instead of SetStyle would be tedious. Even in other APIs like MFC hyou have to resort to SetStyle (which wraps SetWindowsLong(GWL_STYLE,...) ). Some of the styles in ControlStyles are .NET specific; meaning they're only handled as a cohesive attribute in .NET. I don't know of any exhaustive lists that would give you the information you want. Maybe you could detail what you want to do or why simply calling SetStyle doesn't suit your needs. PeterRitchie.com Re: Setting Style (SetStlye Method) With API THEMYTH25-Apr-05 9:57 THEMYTH 25-Apr-05 9:57  Well Thank you for your answer Your answer was just like i guess SetWindowsLong api does not support all of these styles, we need to use others i think Why dont I call the SeetStyle , because i do create a window using CreateWindowEx and all the other operations like Moving, Showing the window or drawing line, filling a rectangle will be performed by APIs. I want to do everything with apis. Because the way is faster!! Thanks anyway.. Best Regards Emre YAZICI Re: Setting Style (SetStlye Method) With API Peter Ritchie25-Apr-05 10:37 Peter Ritchie 25-Apr-05 10:37  Are you using the Win32 API, via P/Invoke? Why are you using .NET at all if you're simply doing everything via Win32 API? PeterRitchie.com Re: Setting Style (SetStlye Method) With API THEMYTH25-Apr-05 19:15 THEMYTH 25-Apr-05 19:15  I tried both, I mean 1 ) I have tried writing a grid control with usercontrol and .net frameworks' Graphics object( using Drawline, FillRect...) 2 ) I have tried the same thing with CreateWindowEx, LineTo, MoveToEx .... When I compare them the second one was faster than the first one This is why i want to use APIs Best Regards Emre YAZICI Re: Setting Style (SetStlye Method) With API Peter Ritchie26-Apr-05 18:13 Peter Ritchie 26-Apr-05 18:13  If it's a stand-alone application (i.e. not client-server) then I would suggest just writing it in C++. The work involed in marshalling all the API structures and data just isn't work the time otherwise. If speed is that much of an issue for you. Even with .NET 2.0 there are some performance differences between .NET applications and "native"/unmanaged. see http://www.sysinternals.com/blog/#111409937327999900[^] PeterRitchie.com Re: Setting Style (SetStlye Method) With API THEMYTH27-Apr-05 7:40 THEMYTH 27-Apr-05 7:40  Of course, c++ is the best way of doing that, I was looking for a way to do it in VB.Net or C#.Net Thank you anyway Best Regards Emre YAZICI Re: Setting Style (SetStlye Method) With API HumanOsc28-Apr-05 5:53 HumanOsc 28-Apr-05 5:53  It'S funny... i have made some same tests... the better performance dosen't comes from the native window creation, beacause the control class do the same thing (only one time)... The better Performance comes only from the usage of native drawing functions... Re: Setting Style (SetStlye Method) With API THEMYTH28-Apr-05 9:30 THEMYTH 28-Apr-05 9:30  Of course it comes from the usage of native drawing functions Best Regards Emre YAZICI Re: Setting Style (SetStlye Method) With API HumanOsc28-Apr-05 5:18 HumanOsc 28-Apr-05 5:18  Hello... At first... It don't exists any API Functions for setting Doublebuffer... It's only implemented in the controls class to perform manged offscreen drawing operations... It's a simple concept for flickerfree drawing... There are many good articels about offscreen drawing at the Codeproject... It's absolutly not recommend to completely rewrite a smarter Control Class which derived from the NativeWindow... They will come more and more problems when you implement multithreading situations... When you only rewrite the control class to perform faster drawing operations then create a class which derived from the system.windows.forms.control class override or reimplement the OnPaint, OnPaintBackground method to perform native drawing operations and doublebuffering effect... Everything else makes to much troubles in my mind... Good Luck... Re: Setting Style (SetStlye Method) With API THEMYTH28-Apr-05 9:34 THEMYTH 28-Apr-05 9:34  I am actually going to write a control class with only apis (without using nativewindow class) For the Events, I will use the WindowProc Api to handle the events For the drawings, I will use the MoveToEx LineTo DrawText FillRect... apis For the styles and messages, I will use SetWindowLong and SendMessage apis As I mentioned , the double buffer could be created by using the CreateCompatibleDC api, which creates an extra buffer for graphical operations. Thank you Best Regards Emre YAZICI Re: Setting Style (SetStlye Method) With API HumanOsc28-Apr-05 22:19 HumanOsc 28-Apr-05 22:19  Your concept is for me really clear... It was only a hint in front of rewritting the complete control class, because it's absolutly enough work to implement (savely) the native drawing functions in the control class... I don't believe that you really see the problems in front of native resources and the gabrage collection routine... - You must manage ((re)allocating, deleting) all native Resources for all possible situations, which is not the problem but many code... - They are also several handle protector meachanism in the control class for preventing memory leaks which can created during the gabrage collection routine... You see it'S not so easy to create a save and stallable control in front of all these aspects... Best regargs, and good luck...

VS.NET 2003 won't do it. Remember, the compilers are built into the .NET Framework, not Visual Studio...
