You know, it would've been faster to go to Dundas's site and look instead of waiting for a response here.

Infragistics has one (but their modular painting controls are incredibly inefficient under heavy loads), as well as ComponentOne. Of course, google will return you some other solutions as well.

Thanks. I've done a google and there are a few interesting products. I was hoping that maybe somebody here would have been able to tell me which are worth using and which not. Trying to find a decent tool comparision is very hard. I like the Dundas stuff, you know what you are getting.
The comments about Infragistics are useful though. The kind of stuff I need to know.

Hi all @ codeproject,
I've build a simple mdi application. It has 1 mdiparent, and
2 mdichild forms. The 1st child form is docked left, the second is
docked fill. The code to create the child forms:
form = new Form();
form.MdiParent = this;
form.Dock = DockStyle.Left; // or DockStyle.Fill for 2nd
The error:
When I click the left docked window, the second window(DockStyle.Fill) slides under the left docked window. Clicking the DockStyle.Fill window when it's slided under, makes it pop back to it's correct position.
What the hell am I doing wrong?
|

|

I believe the problem is the order that these forms are added. If the 'fill' window is added first and the 'left' window is added second, the docking does not work properly. You should add the 'left' first and then add the 'fill'. While this doesn't make much sense, we're dealing with 'Uncle Bill' so we do what we have to to make it work.
Good luck!

I have a set of business objects on a server, replicated on a client. The state of the client should always, after a work unit, or session, should be replicated on the server, i.e., when a user clicks save on the client after adding a new item, the Save method of the object persists its state to the client database.
I now want to transfer that state to the server, instantiate an object of the same class on the server, and invoke its Save method, thus replicating exactly the client operation.
Am I mad, or is this a workable solution? I am trying my best to keep all responsibilities and encapsulation, and avoid code in the objects knowing if they are client side or server side.

Idea 1:
Write a wrapper for the objects, which contains the same methods and properties. The client creates a new wrapper object. The wrapper constructor creates a local object, and an object on the server. Whenever the client calls a method of the wrapper, it calls this method on the local object _and_ on the remote object. If multiple users work with the same object, you have to synchronize the local object with the server object before every call.
Idea 2:
When the client opens an object, set a "locked" flag on the remote object. The client can work with the object, and when the user clicks "Save", it is replicated on the server and the "locked" flag is reset. The saved/unlocked objects will always be equal.
|
|
|
|
|
My problem here is that the client normally only connects to the server once a day, normally by a dial-up, so the wrapper can't call methods on both objects at the same time. My biggest issue is the creation of the remote object on the server after it has been created on the client.
Once it exists on the server, by whatever means, I can just execute method calls on the server at the same time as the client.
|
|
|
|
|
Why isn't it possible to serialize the new object on dialup, deserialize it on the server, and then save it?
|
|
|
|
|
It is possible, and probably what I will do, but I will have to serialise it before saving it on the client so that it is still in its unsaved state on the server. This way exactly the same operation is performed on both objects, leaving them in the same state.
Subsequent operations on the client object, except for editing, will only require the same operation on the server, and not a transfer of the whole state.
|
|
|
|
|
- User saves the object offline: Serialize it to a temporary file.
- User dials up: Deserialize the offline-object (you're back to the state before the save-button had been clicked), serialize it to the server, save on server, save on client.
Everything you would send to the server if you were connected can be sent to a file. On dial up you can read the changes from the file, including all serialized object which has been created offline.
|
|
|
|
|
The problem is that the user will need to access the object in its after-save state before connecting to the server. Most clients will only connect daily, in the morning, or at close of business.
|
|
|
|
|
You can store all the method calls (which you would send to the server if there was a connection) to an "objectID.log" file, and the object itself to an "objectID.obj" file. When the client connects, you deserialize the object from "objectID.obj" and save it on the server, next you read and send the after-save actions from "objectID.log".
|
|
|
|

Yes, I am thinking of using SOAP objects to format the method calls in a standard way, without too much coding, and storing the SOAP method calls on top of the object state in a FIFO queue. When the queue is serviced, the first item off should be an object, and every subsequent item until the next object is a method call for the first object.

I have found a lot of information about how to import C functions from DLL's and use them in C# but nothing about how to use a static C++ lib or calling unmanaged C++ "directly". Is this not possible?

I want to read a char from console (like Console.Read) but I need to not wait the ENTER Key.
I know that it can be done using Windows API but this solution doesn't work for me since I'm not using the windows shell (cmd.exe). In fact, I'm running this appication through Cygwin telnet from a VT100 terminal.
I guess that it could be achieved creating a new class which inherits from TextReader and set it as a console stream reader (Console.SetIn), but I'm not sure (still looking  ). Any suggestion/samples?
thanks.

You want to read a char from console but you need to not
wait the ENTER key,It is possible?
I do not think so.Please forgave my ignorance,you do not
enter the key how the computer know that when your inputing
is over.I think maybe you can change the ENTER key to another key .
sorry for my poor english and ignorance.

It's simple: the input is ready after reading one char. The ENTER key is like any other character and can be read so I could know when the user's input is over.
I just want to read characters one by one, byte by byte.
It can be easily done with C/C++, but I don't know how to do it with C#
In fact, "ReadConsoleInput" from kernel32.dll does what I need but I can't use it as I have explained before.

Oh,I know what is your means.
you want to do :while((c=getchar())=="key");
maybe you can do it in C# with the same way.
I will try it hurry up.
sorry for my poor English.

The MSDN doc says that Console.Read()
reads the next Character from standard
input.
Thank You

I have gotten some information about it. It works in the Console but I still need to get it working in my particular environment. If anyone is interested:
