I Checked your code for deleting the multiple items from the registry and it works fine, if doesnt work means check the checkbox comparison operations.
Also I doubt on the action performed inside the second for loop, the checkBox content is checked against its own value was it v[i] or t[i] arrays?

If you had stepped over your code, you would have seen what the problem is. Basically, you're iterating over one list of values, and you're getting one single value from the other list to compare it to. Try iterating over the selected items from the list box as well, and do your comparison in there.
Now, a more important point is that your comparison code is using terrible variable names. I ended up getting confused by your t and v variables.

Hi,
I am trying to trite a small app that acceses internet browser history on IExplorer using its registry. Somehow i cannot delete the URLs that have been viewed.
note: After accesing the registry i store the data in a checkedlistbox. Any help?
private void Delete_Click(object sender, EventArgs e)
{
RegistryKey key = Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Internet Explorer\\TypedURLs", true);
string[] v = key.GetValueNames();
string[] t = new string[v.Length];
int count = checkedListBox1.Items.Count;
for (int i = 0; i < v.Length - 1; i--)
{
t[i] = (string)key.GetValue(v[i]);
if(t[i] == (string)checkedListBox1.SelectedItem)
{
key.DeleteValue(t[i]);
}
}
for ( int i = count; i > 0; i--)
{
if (checkedListBox1.CheckedItems.Contains(checkedListBox1.Items[i - 1]))
{
checkedListBox1.Items.RemoveAt(i - 1);
}
}
|

Um:
for (int i = 0; i < v.Length - 1; i--)
{
t[i] = (string)key.GetValue(v[i]);
i-- ? Really? 
We all do it at some point...

As I said - we've all done it!

I think it was nearly OK before -- I find removing items from a list in reverse is easier -- but you would need to use
for ( int i = count<big>-1</big>; i ><big>=</big> 0; i--)

Hello
I am trying to use a method that reads all the values from a subkey but something seems to be wrong...can anyone tell me the corect way to do it?
<pre lang="c#">public string[] ReadValues(string rkey)
{
RegistryKey key = Registry.CurrentUser.OpenSubKey(rkey);
string[] VNames = key.GetValueNames();
string[][] values = new string[VNames.Length][];
string[] v = new string[VNames.Length];
for (int i = 0; i < VNames[i].Length; i++)
{
values[i][0] = VNames[i];
values[i][1] = (string)key.GetValue(VNames[i]);
v[i] = values[i][1];
}
return v;
}
|
|
|
|
|
this is one of the easiest exceptions can be resolved by debugging your application. put a break point at this line
RegistryKey key = Registry.CurrentUser.OpenSubKey(rkey);
and debug your application.
most possible case is key or VNames variable is be null.

Is there a way to tell the binary reader how many characters to read because i need the code to read certain amount of bytes in every row of the code and this code i want to read the first row i need to read only 10 Bytes and not the whole row
this is a part of the code that reads from the file
string emriK = brHuazimet.ReadString();
now i know how to write this string into the file i am going to write after reading this part but when i try to read it reads to much from the code
If u need any more explanation let me know
|
|
|
|
|
Yes its possible to read selected no of byte. Use the Read method instead of ReadString. check
here for Read Syntax[^]
/Edit Sorry I dont know what happend I just updated the link path again

My advice is the same as I offer in response to most socket-related programming questions: don't roll your own, there's no point. Socket code is hard to write well and even harder to test thoroughly.
Instead, spend a bit of time getting your head around ZeroMQ[^]. Trust me, it will be time well spent. What you are trying to do is easily achieved with ZeroMQ. Look at the dealer-router & publish-subscribe patterns. I think this is the sort of thing you're after (taken from the ZeroMQ Guide) :-
https://github.com/imatix/zguide/raw/master/images/fig59.png[^]
Just to show how easy things can be with ZeroMQ, here's the complete code for a bare-bones chat client & server console app that does basically what you're after.
First, the server:-
using System;
using System.Text;
using ZeroMQ;
namespace ChatServer
{
class Server
{
static void Main(string[] args)
{
ZmqDealerSocket dealer = new ZmqDealerSocket();
dealer.Bind(args[0]);
ZmqPublishSocket publisher = new ZmqPublishSocket();
publisher.Bind(args[1]);
dealer.OnReceived += delegate(Byte[] bytes, bool multipart)
{
Console.WriteLine("Received from client: " + Encoding.UTF8.GetString(bytes));
publisher.Send(bytes);
};
while (true)
System.Threading.Thread.Sleep(1000);
}
}
}
...and the Client :-
using System;
using System.Text;
using ZeroMQ;
namespace ChatClient
{
class Client
{
static void Main(string[] args)
{
ZmqDealerSocket dealer = new ZmqDealerSocket();
dealer.Connect(args[0]);
ZmqSubscribeSocket subscriber = new ZmqSubscribeSocket();
subscriber.Connect(args[1]);
subscriber.Subscribe("");
subscriber.OnReceived += delegate(byte[] bytes, bool multipart)
{
string[] msg = Encoding.UTF8.GetString(bytes).Split('|');
Console.WriteLine(String.Format("{0}: {1}", msg[0], msg[1]));
};
while (true)
dealer.Send(args[2] + "|" + Console.ReadLine());
}
}
}
Finally, a batch file, test.bat, to demo it...
start "Server" cmd /T:8F /k ChatServer.exe tcp:
start "Jim" cmd /T:8E /k ChatClient.exe tcp:
start "Dave" cmd /T:8E /k ChatClient.exe tcp:
start "Pete" cmd /T:8E /k ChatClient.exe tcp:
How easy could it be??? 
Let me know if you want the VS2010 solution zip & ZeroMQ wrapper DLL I used...

Interesting.
Have you used it in any high volume systems? Where that would be proven production performance or realistic performance profiling?
|
|
|
|

Nope, not personally, though many people have. We use it to pass messages between sites on our EPOS systems, but it's low-volume stuff.
ZeroMQ is very fast. Here[^] are the official performance tests on the ZeroMQ site, and this[^] is a performance comparison between RabbitMQ, ZeroMQ and QPid on Apache. ZeroMQ was over 60 times faster than RabbitMQ and 250 times faster than Qpid. Note, however, that these tests were a C++ application. Putting a C# wrapper around ZeroMQ slows it down somewhat, but makes it *so* easy to use 
UPDATE: The RabbitMQ/ZeroMQ/Qpid test in the link above may not have been fair - see the comments regarding whether message persistence was enabled. Final opinion seems to be use ZeroMQ for socket comms but if you need an MSMQ-type message queue with message persistence use an AMQP app like RabbitMQ...

Unfortunately I don't place much credence on benchmarks. Real world stuff is always more messy.
