There are several native functions like EnumWindows or EnumChildWindows that could be used. Take a look here to get an overview. More information on how to use the native functions in C# are provided by pinvoke.net.

The C# compiler is included in the .Net Framework - the name of the compiler executable is csc.exe (for C Sharp Compiler).

created a setup project for my comapny (windows based application) using .NET Setup and Deployment project (Setup Project). I want to change the registry enviroment variables for the current user, which I easily add in their registry editor. When I install the setup in fresh computer, its instals ok and shows the updated environment variables (Right click on my computer -> properties -> Advanced -> Environment variables) but they did not work. If i open the dos window (cmd.exe), and run "set", its did not display the updated environment. Even reboot didn't fix it. I have to manully edit those value in order to take effect, which is not acceptable at user point.
It seems like very basic feature to me, when you deploy the application, you want to change the environemnt variables. Is this a knows bug or I am missing something.
Please help me..

I have to concatenate an unknown number of byte arrays, into a large byte array.
Do you know how can i accomplish this, optimally?

I guess get pointers to arrays' bases and use them (the array sizes too) with the memcpy function, accessible from C++ (i think it's in memory.h).
Simplicity?
Create a big array and copy inputs into it with the Array.Copy(Array, int, Array, int, int) method
there are no facts, only interpretations

Use a memory stream:
byte[] arr1 = new byte[] {1,2,3,4};
byte[] arr2 = new byte[] {9,8,7,6};
byte[] arrFin;
using (MemoryStream ms = new MemoryStream())
{
ms.Write(arr1, 0, arr1.Length);
ms.Write(arr2, 0, arr2.Length);
arrFin = ms.ToArray();
}

I used GetBuffer and it returned an array larger then the actual number of bytes inside (it grows by doubling the current size).
Thank you!

Have you looked into creating a SoapExtension for debugging purposes? Can be helpful.

Hi everyone,
Could you please tell me what the best and error-prone way to sign and verify XML files exists? Which CSP provider exists on all 2K and XP machines? What is the optimal key-length so that it works with all localized Windows versions?
The only constraint I provide is the ability to sign with the private key and to check with the public key.
Thanks in advance.

Your smile shows you have no practical experience in this subject and do not understand that there are problems with both 1.0 and 1.1 crypto API implementation. So I am really sorry for the traffic you've wasted when posting your smiley.
Novichek?

Yo, I wasn't answering your question. I was just making a joke out of "error-prone". By definition error-prone means "capable of making an error". I'm sure that's not what you are looking for.

By default Katakana charactor (in Japanese) takes two bytes, but it can also be displayed using one byte(that reduces charactor width). Is there any standard way to convert two byte Katakana charactors in to one byte charactor in a given string that may have Kanji and Katakana in it.
Please guide.

No there isn't. You'll have to use some customized compression technique on the strings. But, when you wanted to do ANYTHING with them, like display them or manipulate the strings in any way, you'd have to decompress what your using.

Create Form1 as Singleton class. this will solve the problem
|

Try this.
<br />
private Form Frm;<br />
private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
if(Frm!=null)<br />
{<br />
Frm.TopMost=true;<br />
Frm.Activate();<br />
<br />
}<br />
else<br />
{<br />
Frm=new Form();<br />
Frm.TopMost=true;<br />
Frm.Show();<br />
}<br />
<br />
}

Hi, all.
I am working on a C# code that can retrieve system log by using WMI.
However, the code is working fine under windows 2000, but got error messages
under Windows XP.
The erro message is :
Unhandled Exception: System.Management.ManagementException:Access denied.
at System.Management.Management.Exception.ThrowWithExtendedInfo(ManagementStatus errorCode)
at System.Management.ManagementEventWatcher.Start()
Part of my code is like following and I believe this is where the problem at:
----------------------------------------------------------------
public static ManagementEventWatcher getWatcher(string comp, string LogName)
{
ConnectionOptions co;
ManagementPath mp;
ManagementScope ms;
WqlEventQuery EventQuery;
ManagementEventWatcher watcher;
string wql;
string wqlAnd;
co = new ConnectionOptions();
co.Timeout = new TimeSpan(0, 0, 60);
co.EnablePrivileges = true;
mp = new ManagementPath();
mp.NamespacePath = @"\root\cimv2";
mp.Server = comp; // comp is the computer you are connecting to
ms = new ManagementScope(mp, co);
Console.WriteLine("host is" + comp +"Logname is "+LogName);
switch(LogName.ToUpper())
{
case "ALL":
wqlAnd = "";
break;
case "SECURITY":
wqlAnd = " AND TargetInstance.Logfile ='Security'";
break;
case "SYSTEM":
wqlAnd = " AND TargetInstance.Logfile ='System'";
break;
case "APPLICATION":
wqlAnd = " AND TargetInstance.Logfile ='Application'";
break;
default:
wqlAnd = "";
break;
}
wql = "select * from __instancecreationevent where targetinstance isa 'Win32_NTLogEvent'" + wqlAnd;
EventQuery = new WqlEventQuery(wql);
watcher = new ManagementEventWatcher(ms, EventQuery);
Console.WriteLine("end of first watcher");
return watcher;
}
---------------------------------------------------------
Could any of you tell me how to solve this problem?
Thanks a lot.
