I was wondering what is the best way to implement a timer for my pong-type game.

I have a namespace with two classes in it: one class is for methods to work on the application(eg windows media encoder stuff, buttons and the like). The other class contains methods which are used by another application to remotly control this application. I want one class to call a method in the other class, and to do this it seems that i need to make the "called" class' method static. when i do this the comboboxs need an object reference. I tried making them static but i then when i ran the application, the boxes were not filled with what they should be filled with!!!
I dont know how to get round this problem!
Im sure ive made the description as clear as mud!!! 
Any help would be much appreciated as i need this problem solved asap!
Thanks

yes 
but FWIW you can't call static methods remotly if that's what you are trying to do.

Hi,
I'm creating a client/server business application using .net remoting. I want this program to be dynamic and extensible, this way i dont have to adapt the program with every minor change. So i was trying to create a module/plugin like architecture. Somehow my program doesn't work fine, let me explain it in some details:
-The server has a remote singleton factory, the client uses an interface to contact it.
-The client requests its own SessionObject via the server factory, this SessionObject is defined by an interface. First problem: the interface needs to be compiled into one assembly, so i have to make a shared assembly which i dislike.
-The client then request a, serializable, object which contains references to modules inherited from MarshalByRefObject (these modules contain business logic). This is the second problem, again i need to compile the interfaces of these modules into one shared assembly, that means that i need to recompile the server and client with a reference to the interfaces.
So because of all these shared assemblies my application doesn't become very dynamic.
Any tips?

If I understood correctly, basically what you have is an interface, but you don't want to enforce compile-time interface implementation, because this would lead to deployment problems.
The only solution I see* to a plugin model like that is calling the method by its name as a string (see Type.InvokeMember), using Reflection. Obviously, this leads to some relaxation in compile-time checking, but, as long as your interface is not too complex, you won't run into trouble.
[edit]By the "only solution I see" I am assuming you already have investigated the possibility of proper version management and it does not solve your problem.[/edit]

Tarmin,
I might come across a bit simplistic etc here but I don't really see your problem. The point of interfaces are that they define an "immutable contract of service" between the client object and the server object. The idea being that so long as the interfaces stay the same the underlying implementations can change with theoretically no breakage to the system. If you need to add more functionality to the system not covered by the interface, you create a NEW interface and don't break the old one.
In this respect having an assembly which contains only interfaces is actually a good idea as it is a central place to define the contracts by which the parts of your system communicate.

I had a nice and refreshing sleep, it made me realize that you guys are right about the concept of interfaces. Besides i found some nice tricks with reflection to make things more dynamic!
Thanks guys!

How can I fullfil the xml information for a enumerated type?
CODE_________________________________________________
public enum SegmentationTypes {SingleFrame = 1, FixedSize = 2, BottumUp = 3, Cumulation = 4, ShotDetection= 5, MedianIncremental = 6, Filtering = 7};
END CODE______________________________________________
When I insert the "///" I just get the summary field, and during compilin I get an error: "Missing XML comment for publicly visible type or member SegmentationTypes.SingleFrame" for every type in my enumerated type
Some suggestions?

You should put the individual items on a separate line then stick comments over each enumeration. You said "errors"... do you have "Treat warnings as errors" enabled? Is this something most people are doing nowadays???
Apologies for code layout... 
public enum SegmentationTypes
{
SingleFrame = 1,
FixedSize = 2,
BottumUp = 3,
Cumulation = 4,
ShotDetection= 5,
MedianIncremental= 6,
Filtering= 7
};

Hi.
im creating a control from scratch , inheriting from windows.forms.control
i want to be able to bind this control to a datasource , eg a datatable , iList etc
the data from the datasouce will be painted in the controls onpaint in a grid'ish way.
the problem is that since an ilist and a datatable have almost nothing incommon , so how would i go about to read data from the underlying datasource w/o breaking my neck??
do i have to implement special code to read data from each databindable type/interface?
or is there any form of support for this in the .net framework???
ive found some classes that _seems_ to have something to do whith this , BindingManagerBase and BindingContext , but i might be way wrong here?
can i somehow use one of those or any other class to extract data in the same way w/o having to care about what underlying object is bound to my control???

You will need to use Complex Binding, since you said you are going to display the results in a grid’ish way. Most complex bindings are set to the Data Source property directly, as opposed to using a Binding Object to the DataBindings Collection. This is how the DataGrid does it.
You did not say if you were supplying your own data source or not. If you supply your own Data source, you will have to implement the Ilist and Icomponent interfaces. Does this help?

Have you checked out listcontrol and currencymanager classes?

Hi Everyone
I want to set share permissions which are "Fullcontrol","change" and "read" through code. But I can't find any c# classes for this. I can set all the security options using ActiveDs but I can not set any share level permissions.
Can anyone please help me?

ok, so I have this....
private void Form1_Load(object sender, System.EventArgs e)
{
Process [] localByName = System.Diagnostics.Process.GetProcessesByName("notepad.exe");
}
So, first things first. From what I understand, the variable localByName (assuming it is a varible, and if it is what kind?) is storing the data from what ever "GetProcessesByName" returns, correct? If so what kind of data is it returing? A sting? A bool?

It is a variable and it is returning an array of Process objects.
You can access a Process object from the array like this:
Process p = localByName[0];
You can loop through the array like this
for(int i=0;i<localByName.GetLowerBound(0);i++)
{
}

hi,
how can i dequeue object from a Queue when the elements type of the queue is a structer?
for example, i use the following code to Enqueue the object 'new_object' which type is ABCD :
ABCD new_object=new ABCD();
MyQueue.Enqueue (new_object);
how to Dequeue?
this method doesn't work:
ABCD another_object=new ABCD();
another_object=MyQueue.Dequeue ();
any help?

MyQueue.Dequeue ();
Dequeue() returns an object, so you need to cast back to the original object type.
another_object = (ABCD) MyQueue.Dequeue();

Can you tell me how to create a completely hidden windows form. I'm using it just for its message pump. I best I can do at the moment is hide from view, taskbar but no the Alt-Tab menu. And the user can still close it when it has focus and using Alt-F4.
I'm using a hidden form as I want to pass data using BeginInvoke between threads.
|
|
|
|
|
Well, have you thought of setting the forms visible property to false before calling its show method?
|
|
|
|
|
That doesn't work! Calling show just set visible back to true. Also the form still shows up in the taskbar and Alt-Tab menu. Instead I'm just using a Control instead of a Form.
|
|
|
|
|
I'm not sure exactly what you are trying to do, however, do you need to call Show? just instantiate the form, then do what you need.

I have a problem .. One of my applications is loading DLLs into memory but isnt unloading it.
I want to wirte a program that will get the address of a particular DLL loaded into memory and then unload it...Any ideas ?? Is it possible

By DLLs are you meaning .NET Assemblies or are you meaning C/C++ DLLs?
Once .NET Assemblies are loaded into an AppDomain they cannot then be unloaded unless you unload the entire AppDomain. Not sure what you can do if it is a C/C++ DLL, you could try calling FreeLibrary but there might be hidden functionality relying on that DLL still being loaded.
