So your program would take a program X and a file of input Y then say yes/no to whether X will exit if given Y. Re: New Ideas For graduation Project BoneSoft24-Jul-07 10:46 BoneSoft 24-Jul-07 10:46  You could write an app that thinks up graduation project ideas. Just an idea...

This Event Server will receive requests , process them , and send back a answer to the caller . Can we use the Event , Delegate to do that ? If yes , how easy is it ? If not what is the solution to write this Event Server ? Please note , I'm a beginner in C# . Many Thanks GDO Re: event , delegate , publish ramdil24-Jul-07 6:31 ramdil 24-Jul-07 6:31  Hi You can create an recieve event handler on both of the application and can be used to recieve incoming messages after receiving message do the necessary operations in local methods of corresponding application some thing like this obj.OnReceive += new obj.OnReceiveHandler(this.ReceiveMessage); this is the event hander and ReceiveMessage is the local method in the other application declare the following public delegate void OnReceiveHandler(string Message); public event OnReceiveHandler OnReceive; where OnReceive will be local method in that application. Hope this will give you some idea Regards DilipRam Re: event , delegate , publish cleverhouse24-Jul-07 6:44 cleverhouse 24-Jul-07 6:44  Thanks for the quick answer. I will try doing something like you suggested. Thanks again. Re: event , delegate , publish led mike24-Jul-07 9:42 led mike 24-Jul-07 9:42  cleverhouse wrote: I'm a beginner in C# . So what other languages do you have experience with? Have you previously created a Windows Service? Have you previous experience with Interprocess Communications? If so, what communications mechanisms? Sockets? COM? CORBA? RPC? Message Queues???? Re: event , delegate , publish BoneSoft24-Jul-07 10:44 BoneSoft 24-Jul-07 10:44  Sounds to me like you need to look into web services. Events and delegates not only accross threads but machines would take a lot of remoting. When web services were developed for just this situation. Try code model generation tools at BoneSoft.com. Using a USB Joystick in C# Yeates24-Jul-07 5:41 Yeates 24-Jul-07 5:41  Hi, I'm new to both C# and Windows programming in general but would like to use a USB joystick in my application. I managed this using Delphi and wonder if the same multimedia joystick API can be used in a similar way? It seems that Direct Input is mentioned more frequently in reference to C# although I only need a simple x,y,z value and some buttons presses from a basic joystick. Can anyone reccomend a simple way to achieve this? Thanks in advance! Christian Re: Using a USB Joystick in C# Member 1678927-Oct-13 1:48 Member 16789 27-Oct-13 1:48  Hi I recommend DirectX DirectInput. I used a class developed by Alex Ward several years ago. First you need to install DirectX SDK. Unfortunately I couldn't find the original article at www.trossenrobotics.com but I can send you the code and SDK installer. COM interop question mhp13024-Jul-07 5:21 mhp130 24-Jul-07 5:21  Hi, I have a C# window application calling a COM DLL written in VB6. I direct import the DLL using Add reference -> COM. Now when I change the DLL and recompile it without changing the interface (the public method I use to expose), My C# got an exception that it could not find the interface. I need to derefence and then reference the dll again in my C# project to make it work, why is that? Does it mean I can not distribute dlls in a .NET environment without re-compile the application referencing the dlls? Thanks Re: COM interop question originSH24-Jul-07 6:27 originSH 24-Jul-07 6:27  When you compile it does it change the version or the guids?

Is there a way to add this without losing those boxes? Could I make my own button on my form that would call the same thing? (if so how would I do it?) Thanks! Calendar control help swissmiss8624-Jul-07 4:42 swissmiss86 24-Jul-07 4:42  is it possible to pick more than one date(non continuous) using the calendar control? If so please help me. Re: Calendar control help Paul Conrad24-Jul-07 5:43 Paul Conrad 24-Jul-07 5:43  Assuming you are talking about the MonthCalendar control, from a quick glance, doesn't look like it.  You could always create a custom control derived from the MonthCalendar control.

You'll likely have to do it manually since you already have a model built. But you can get a good idea of how to alter your model by producing a sample of what XML the model should produce, and running it through XSD.exe or Skeleton Crew[^]. It's really not difficult at all. Try code model generation tools at BoneSoft.com.

Re: Serialization BoneSoft24-Jul-07 5:29 BoneSoft 24-Jul-07 5:29  True, but that might be gross overkill... Depending on the project. I had to deal with a 'standard' when I was working for a travel site. It was a joke. HUGE set of schemas that all people we interacted with were 'compliant' with, while all having completely different models. But I've never looked at SVG, I'd assume since their problem domain is more technical they'd have a better standard model. But also, I was thinking if he's already got a model built and working, he'd probably want to build an XML structure that closely resembles his model.

Reason being, I am also passing other values from the grid to another form to edit the data. How could i go about passing a true or false value so when my edit form opens the radiobuttons are populated with either a true or false value, based on what value they hold in my datatable? Thanks Re: bool values and radiobuttons originSH24-Jul-07 4:05 originSH 24-Jul-07 4:05  If you mean how do you pass the values to the new form, you can either do it via the constructor or Properties. If you mean how do you set the radiobuttons is the .Checked property.
