Sorry, I am not following you, you said:

The documentation contains the new classes that work with DataGridView to accomplish similar ( but likely greater ) functionality, you don't have to "implement the class yourself".

They provide classes to work with the table elements such as cells, columns and so on, but I need to work with the table as a whole, do you get it now? And that's what I don't see in the documentation, classes to work with the entire table, if you know of any, please tell me.
I hope I made myself clear enough this time.
Thanks again,
Kenia

Good point the Rolling Stones song!!
It's not that I want to do it that way, it's just that there are lots of lines of code that work with the table, so if I start working with cells and columns then I'll have to change pretty much of the code, and it's not a good idea, as there are other functionalities to be added to the project and the DataGrid replacement is just one of a long long list. That's why I needed a similar table class for the DataGridView.
Thanks anyway for your concern,
Kenia

Have you not heard about the Microsoft .NET Platform yet? That's what this forum is for not Java. Actually this site is focused on the Windows platform. I don't believe there even is a Java forum. You are probably better off finding another site for Java questions. At the least you should probably ask your question in the "General Discussions" forum. Good luck.

BTW, why does CP now describe itself as "Your Development Resource?" It creates the impression that it deals with all development rather than Microsoft-centric development. Maybe this is why this guy is asking about Java?

It feels a bit silly answering a message that isn't there any more, but here it goes
anyway:
1.
there was no need to mention Java, it does not seem essential in your quest; and a lot of
people here are allergic to it, the "not invented here" syndrome you know.
2.
Maybe this link will show how collections typically are implemented:

3.
just keep posting questions in whatever forum seems appropriate, don't get discouraged
by some reactions. And please don't delete messages; if you need to, you can modify an
existing message, adding text, and striking through stuff.

Hello,
How can I create a sorted list in .Net?
Something like:
SortedList<string> L = new SortedList<string>();
L.Add("B");
L.Add("A");
Now L[0] should contain "A".
I found class SortedList<key, value=""> but this requires two types which seems an overkill to me.
Thanks in advance,
Kees Vermeulen

Pretty much any collection in .NET can be sorted with the aid of the IComparable interface.
|
|
|
|

Pete,
I want the sort order to be maintained so that new items are inserted at the right position in the list without calling List<>.Sort every time.
Kees

Well, you wouldn't do this since the more items you add to the collection, the longer the process of adding a single item would take.
Sorting is a presentation layer requirement, not something you normally do as part of data storage. If you wanted the list sorted, you would normally call a method on the collection to return the sorted list.

Thanks for your answer.
I have many occasions in which I use sorted lists! For example to prevent insertion of duplicate items and for fast retrieval of existing items.
For example, in my situation I have a function parser which can handle various predefined functions. These functions are simply strings and I want to test if a certain string is a predefined function. Looking up a string in a sorted list would be much faster than doing so from an unsorted list.

Don't use a sorted list for this. This is what a key/value paired collection or is for, such as a Dictionary.

Thanks,
I do not always have a key AND a value. Sometimes the Key IS the Value and therefore using a Dictionary or SortedList is cumbersome. However, from your answers I conclude that under .Net this is the way to go.
Kees

I would then suggest composing a new class that contains a Dictionary, but adds overloads to methods such as Add, in which you use the value as a key.

If you find the .NET collections not convenient or flexible enough for your tastes be aware that there are some well-tested alternative open source collection libraries around, e.g.,
PowerCollections[^]
Welcome to Power Collections, A Community Project to Develop the Best Public License type safe Collection Classes for .NET. Power Collections makes heavy use of .NET Generics. The goal of the project is to provide generic collection classes that are not available in the .NET framework. Some of the collections included are the Deque, MultiDictionary, Bag, OrderedBag, OrderedDictionary, Set, OrderedSet, and OrderedMultiDictionary.
and
The C5 Generic Collection Library[^]
C5 is a library of generic collection classes for C# and other CLI languages and works with Microsoft .Net version 2.0 and Mono version 1.2 and later.
C5 provides functionality and data structures not provided by the standard .Net System.Collections.Generic namespace, such as persistent tree data structures, heap based priority queues, hash indexed array lists and linked lists, and events on collection changes. Also, it is more comprehensive than collection class libraries on other similar platforms, such as Java. Unlike many other collection class libraries, C5 is designed with a strict policy of supporting "code to interface not implementation".
I myself have been using PowerCollections in the past few days in connection with user role management. PowerCollections is a little easier to use as it's a natural extension of the framework classes. C5 is more powerful but rather more esoteric. Also PowerCollections is better documented with intellisense tooltips and so on. Both are accompanied by unit tests.

Hi Kees,
1.
SortedList is a HashTable or Dictionary, so it stores (Key,Value) pairs. If you don't
need values, you could specify "null" for all of them.
2.
Yes, I found the collection names a bit confusing; I would expect a Dictionary to always be
sorted (as in: Van Dale) but that is not how .NET sees it.
3.
Maybe this will interest you:

Well, that's probably just because real world dictionaries are sorted in order for us to find anything in them. If you look at how a paper dictionary works, a sorted list would be digital equivalent, but if you instead concentrate on the purpose of a dictionary, i.e. to find single items in a large collection, the naming of the class makes more sense.
Experience is the sum of all the mistakes you have done.

Yes, I know what they do, but why choose names that are counterintuitive, i.e.
don't match real-world terms.
I would prefer a Map for a .NET Dictionary, and a SortedMap for a .NET SortedList
(it isn't a sorted List, in .NET terms it is a sorted dictionary).

They match the real-world items if you think of them from a certain point of view.
Computerised real-world concepts often mimic only some aspects but not all. If you take radio buttons for example, they pop out just like buttons on a real radio, but you can't turn them to change the preset frequency.
Luc Pattyn wrote: I would prefer a Map for a .NET Dictionary
A map to me is something that describes two dimensional geographical data, so that would be even more confusing...
Luc Pattyn wrote: and a SortedMap for a .NET SortedList
(it isn't a sorted List, in .NET terms it is a sorted dictionary).
The internal storage for a SortedList is a pair of arrays, so it actually is a sorted list.
Despite everything, the person most likely to be fooling you next is yourself.

Hello together,
I start a new process inside a system process (IIS web service) like this:
Dim pProcess As New System.Diagnostics.Process
Dim sArguments As String = ""
pProcess.StartInfo.FileName = "process.exe"
pProcess.StartInfo.Arguments = sArguments
pProcess.StartInfo.WorkingDirectory = "c:\temp"
pProcess.StartInfo.CreateNoWindow = False
pProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal
pProcess.Start()
Process is startet, but the window is not visible on the desk. I think, the problem is the system process as father. If the new process throws an exception, the window is visible.
Did anybody know, how I can make the process window visible on the desk? Can be some nice parameters on the process object himself or inside the process (source code is written in VB.NET).
Thanks
Stephan

So why would a Web Service be starting an interactive process on the server?
Since services run under they're own desktop, the window is getting created, just on a desktop that is hidden from view.
