I was wondering whether anyone knew how to go aobut getting a list of all of the keys on the keyboard, like in programs which have comboboxes which allow you to select the keys you're going to use for your shortcut.
I'd appreciate any help you can offer. preferably in j# but anything else is still appreciated
Thanx

Has anyone used the CSLA framework as is? What has been your experience with it? I am trying to figure out whether to create my own framework, which would consist of a subset of the features in CSLA, but not the whole thing (namely remoting) or use it as and extend some functionality to it.
If anyone could provide feedback on their experiences of CSLA.Net I would grately appreciate it.
Thanks in advance.

Hi,
With .NET 3.0 and Vista, i hear that MS is giving us an almost completely Managed API sub-system of Windows OS (maybe on top of or side by side along with the Win 32 sub-system). Is this correct? I could not find any specific mention about thin anywhere in MS site.
Also is it true that .NET 3.0 will only support Win XP SP2 and Win 2003 and above (i.e. Vista, etc) and not Win 98/NT/Win 2K. If that is true (i hope not) then how do we deploy .NET 3.0 apps for Win 98 through Win 2000 users?
Thanks.

Not true. .NET 3 is not a replacement for Win32. .NET 3 is .NET 2 with entensions added. These are Windows Presentation Foundation (WPF), Windows Workflow Foundation (WF), Windows Communication Foundation (WCF), and Windows CardSpace.

True, unless the requirements change at the final release, but I doubt they will.

You don't since those O/S' are not supported. You'll have to use .NET 2 are lower depending on what you're targeting.

I knew this naming decision would cause problems. When it was still called WinFX it was something distinct and didn't cause people to think they needed to upgrade. Not that you need to upgrade from .NET 1.1 to 2.0 if it's working, since you can install the runtimes side-by-side. You can still install .NET 1.1 on Windows Vista Beta 2.

The problems have just begun. Think of how confusing it will be for "decision makers" at companies when they need to decide if they want to use .NET 3 or 2. Well, 3 is 2, but 2 is not 3. Hmm...

:-DDear All,
Did .NET Framework Designers used Design Patterns for their Base Class Libraries? If yes, How? And what are those patterns and especially
in which BCLs?(Mainly my interest is in C#). What are the Top 10 Design patterns used in top 50 BCL(.NET) out of 23 GOF patterns??

Of course!
Raihan Masud wrote: If yes, How?
Various patterns are used throughout the entire BCL.
Raihan Masud wrote: And what are those patterns
These are questions that you'll have to ask the Design Team. I'm willing to bet that it's more than just a few different patterns in a few different places.

hey folks,
what is the fastest way to have a clean fresh System.IO.MemoryStream each time i write into it?
one way is to make a
ms.SetLength(0)
before i write in to it. Another way is to create a new one each time. i think this two methods aren't very fast. is there another posibility to clear a stream?
thanks, bernd

|
|
|
|
No, there isn't. If you want something faster, perhaps you should use something other than MemoryStream. Why the need for speed?
---
b { font-weight: normal; }
|
|
|
|
|
thanks guffa,
speed is always nice to have  and what's faster, setting the length to 0 or create a new one?
|
|
|
|
|
That depends. Setting the length to 0 should probably be faster than creating a new one, but the speed of that single action is not all that affects the speed of your application. A MemoryStream that is reset will probably handle memory allocations differently from a newly created one. I know too little about that difference, and especially too little about what your application is doing, to advice you in either direction.
Don't do premature omtimization. You should always avoid anti-patterns (known bad solutions), but specific optimization should generally be put off until you know where and why you need it.

b { font-weight: normal; }

i integrated ironPython in my application to ensure sccripting support. ironPython writes it's output into a stream.
but you're right...currently everythings works fine and performace is till now no problem.
thanks for your help!

i am currently a developer that uses .net as my main programming environment. and i wanted to know how could i use .net to create License and then in turn use them to protect the applications that i have developed?
can some one please point me into the right direction? posible some tutorials or papers on how i can use .net to implement this????

There's all sorts of ways, but they can all be circumvented as .NET code can be decompiled.

so how would you add a license feature to your applications you developed???

Try to hide some vital code in a C++ component ( not managed ) which also handles the licencing, to slow down people trying to decompile it.

We have windows service as batch application and web application as configuration GUI for batch application. I am trying to package it using VS 2003 Deployment options, not sure which project to choose.
Installing package(setup.exe) should create webforms in Virtual root and install windows service.I know how to use service installer and web setup, but not sure how to combine both.

First, I'm sorry to post it here because I don't know where to post it.
Now to the subject. I have designing a sniffer socket that read a raw packet of network packet (it be IP, TCP, UDP, ICMP, and others). Now I want to send the packet back into network so it can be continued into wide network. But the problem is I not create the server.
More explaination, here I design a socket that read HTTP request, after check the packet with my filter, it will decide the packet will continued or dropped. I have learn socket programming and every example always create a pair (client and server). But this the server is other application (because this I filter HTTP packet, then the server is WebServer that I not design it).
So can anyone suggest me something, like how to build raw socket to send the raw packet.

Ariston Darmayuda.

Hello!
Please, I need help by solving two problems regarding the new DataGridView control.
Here is my simple example code:
// ==================== SNIP ====================
using System;
using System.Collections;
using System.Windows.Forms;
// Add a DataGridView named dataGridView1 to Form1.
namespace DataGridTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
// Create an Order list...
IList order = new ArrayList();
order.Add(new Item(1, "Keyboard", 1, "http://www.keyboard.com/"));
order.Add(new Item(2, "Mouse", 1, "http://www.mouse.com/"));
order.Add(new Item(3, "Monitor", 2, "http://www.monitor.com/"));
// Add a Button column...
DataGridViewColumn col = new DataGridViewButtonColumn();
col.HeaderText = "Link";
col.Name = col.DataPropertyName = "URL";
dataGridView1.Columns.Add(col);
// And fill the DataGridView...
dataGridView1.AutoGenerateColumns = true;
dataGridView1.DataSource = order;
}
}
// Instances representing Order items
class Item
{
private int id;
private string description;
private int quantity;
private string url;
public Item(int i, string d, int q, string u)
{
id = i;
description = d;
quantity = q;
url = u;
}
public int Id { get { return id; } }
public string Description { get { return description; } }
public int Quantity { get { return quantity; } }
public string URL { get { return url; } }
}
}
// ==================== SNIP ====================
1.
How can I achieve that the user can sort the table by clicking the sort glyph of a column? (In the old DataGrid control that works by default.)
2.
The button cells should all show a text like "Link...". But programmatically I need to get the URL value of each cell and not the displayed text. Is that possible?
Numerous thanks for all advices.
Regards,
Amd Opteron

I've not used this control, still in VS 2003  but it seems to me that you need to enable the 'AllowSorting' and 'AllowNavigation' properties of the grid. Presuming of course that this control has these properties!
Hope that helps!

1. Sorting is not automatically supported when binding lists. You will have to bind click events for the headers and sort the list manually (and do a refresh on the grid). With manually I mean using ArrayList.Sort with a defined comparer you have coded.

I have the folowing Problem:
I want to have a ListBox control which is able to display Text und a NumericUpDown control for each Item in the ListBox.
I don't know how to face this problem  .
Should I extend the ListBox class and override the OnDrawItem()  ???
Or start a new control from scratch ???
Any usefull hint is welcome.
