Hello,
The KeyDown even is:
<Occurs when a key is pressed while the control has focus.>
What if i want to see ALL key presses? not only when the control has the focus?
Thanks

On the main form there will be a property called Key Preview. Set that to true and the main forms KeyPress or KeyDown event (I'm not sure which) will be fired before the active control gets the event.
This property is only available on a windows form however, I'm quite sure it's not on any controls.

How can I do the following number 4 and 5 task using client server socket programming?
1. Client send a query as regular text to the server. [I can do this]
2. Server get the SQL from the client. [I can do this]
3. Server execute the query(Select statement). [I can do this]
4. Server return the query result as datatable or dataset to the client [How can I do this]
5. Client get the datatable or dataset and display to the client side.[How can I do this]

1. Don't write everything in bold. It's a plain message, so it's wise to use plain text.

Serialize it into XML, that should do the trick.

Sorry !!!
Can I have sample code for that??

You'd best start here[^], samples can be obtained here[^].
Basically, you transform an object into XML (or binary), send it, and rebuild the class on the receiving end. Something like this;
"Class X -> becomes XML -> gets send -> gets received -> receiver makes class from XML" Enjoy

Hi all
I would like to use Trace class or TraceListener to make code tracing in each thread at a different indendation level.
Function #1 From Thread#1
Function #2 From Thread#1
Function #1 From Thread#2
Function #3 From Thread#1
Function #2 From Thread#2
Function #3 From Thread#2
Most of Trace methods are shared so setting Trace.IndentLevel changes this value for all threads.
If I use 2 different objects for the same TraceListener, like for example ConsoleOutputTraceListener, there is no Thread safety guaranteed ( check IsThreadSafe for each object ).
Do you know some general approach to solve this issue?
Do I have to implement my own logger?
Kind Regards
Mn

One suggestion is to create a thread-safe singleton class.
As you create a thread you should register it with the singleton, which assigns it an indentation level.
Any trace statements should be made through a method on the singleton class, which can then resolve the indentation level.
When the thread ends, it is important to de-register it from the singleton.

Try the following....
Process MyProcess = Process.Start("myApp.exe", strApplicationPath);
Starts a process resource and associates it with a Process component.

You need to use Process Class.
Below is the sample code which is used to open a notepad.
using System;
using System.Diagnostics;
class ProcessStartDemo
{
static void Main(string[] args)
{
Process pr = new Process();
pr.StartInfo.FileName = "notepad.exe";
pr.StartInfo.Arguments = "Sample.text";
pr.Start();
}
}

Hi, I'm trying to get the IP, subnet and gateway for my interfaces using IPInterfaceProperties but both UnicastAddresses and GatewayAddresses returns a collection...
How do I know which one to use?
Here is my loop and for now I'm just using UnicastAddresses[0] and GatewayAddresses[0] but that isn't always right
internal static NetworkAdapter[] AddExtraInformation(ArrayList adapters)
{
NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkAdapter adapter in adapters)
{
foreach (NetworkInterface networkInterface in networkInterfaces)
{
if (!DescriptionToName(networkInterface.Description).Equals(adapter.DeviceName))
continue;
adapter.Name = networkInterface.Name;
adapter.OperationalStatus = networkInterface.OperationalStatus.ToString();
IPInterfaceProperties ipProperties = networkInterface.GetIPProperties();
if (ipProperties.UnicastAddresses != null)
if (ipProperties.UnicastAddresses.Count > 0)
{
adapter.Address = ipProperties.UnicastAddresses[0].Address.ToString();
adapter.SubnetMask = ipProperties.UnicastAddresses[0].IPv4Mask.ToString();
}
if (ipProperties.GatewayAddresses != null)
if (ipProperties.GatewayAddresses.Count > 0)
adapter.Gateway = ipProperties.GatewayAddresses[0].Address.ToString();
break;
}
}
return (NetworkAdapter[])adapters.ToArray(typeof(NetworkAdapter));
}

string hostName = Dns.GetHostName();
IPHostEntry ipEntry = Dns.GetHostEntry(hostName);
foreach (IPAddress ip in ipEntry.AddressList)
{
//Please check ip values
}
For example, if you want to get IPv4 value, use "ip" variable which is using foreach statement;
if (ip.AddressFamily.Equals(System.Net.Sockets.AddressFamily.InterNetwork))
string result = ip.ToString();
Best Regard...

Thanks for your reply
I'm not sure how to tell which nic has the ip-number that I get from using your code.
Anyway, I changed my code to this, looping the addresses and checking for IsDnsEligible, that seems to do the trick or am I missing something?
foreach (UnicastIPAddressInformation address in ipProperties.UnicastAddresses)
{
if(address.IsDnsEligible)
{
adapter.Address = address.Address.ToString();
adapter.SubnetMask = address.IPv4Mask.ToString();
break;
}
}

Hello,
i've got a custom UserControl (UserControl-Class with a panel in it) and now i want to let it interact as a container in the Designer. Well - on the web I found a lot of tutorials for this problem, but my problem is, that the designer doesn't put the Controls i add to my control to the panel. It put them into the UserControl itself.
So how can i tell the designer, that it should use "panel" as it's container and not the UserControl itself? I've tried different thinks like make a own class which extends "System.Windows.Form.Panel" and tell them, that it is the Container for the designer and puttet it into my UserControl but all those things doesn't work...
Thanks for your help

You should have searched on CodeProject.
Take a look at Designing Nested Controls[^] by Yours Truly.
Hope this helps!

I'm having alittle trouble with the SOCKS5 protocol. Maybe someone here can help.
http://www.rfc-editor.org/rfc/rfc1928.txt
the initial request consist of 3 bytes
request[0] = 0x05;
request[1] = 0x01;
request[2] = 0x00;
the response contains 2 bytes
response[0] == 0x05;
response[1] == 0x00;
the next request is 10 bytes
request[0] = 0x05;
request[1] = 0x03;
request[2] = 0x00;
request[3] = 0x01;
(destination IP).GetAddressBytes().CopyTo(request, 4);
int byte1 = (destination Port) / 256;
int byte2 = (destination Port) % 256;
request[8] = (byte)byte1;
request[9] = (byte)byte2;
now this is where im having trouble. with the next response. the first 4 bytes are fine
response[0] == 0x05;
response[1] == 0x00;
response[2] == 0x00;
response[3] == 0x01;
but with the next 4 bytes its supposed to return an IP address to which im supposed to send udp data to. the bound address, but it returns an ip of 0.0.0.0. then the next two bytes are fine which is the bound port to send the udp data to. now why would it be returning a null ip? am I just suppsoed to use the proxy IP when it comes to UDP?

I working on application in which i need to log urls browsed in internet explorer. For this up till now i am using low level key hook to trigger application to copy address bar content i.e. user have to press 'c' to log the url.
But i need to automate this part such that when ever there is change in url at address bar, trigger is generated to copy it to log file.I need some pointer for this task.
language preference is c# as i need to integrate it in latter dev stage.

I'm trying to get my PropertyGrid to refresh when the control in the designer has finished resizing, i'm not exactly sure on how to do this. Is there a way to get it to update on a value change as i'd rather not have to pass a reference of the property grid to the control being resized in order to refresh the values.
I'm not sure if i explained that to well 
|
|
|
|

Most controls hanve a OnResize event, if not you will need to search the event list and choose one. Either refresh the property grid in that event or have the property grid subscribe to the controls event.

To clarify things. Is the PropertyGrid you talk about the one in the Visual Studio IDE, or one you have put on your form?
