I don't know a lot about C#, but I do know there is a Windows API to get this directory:
UINT GetWindowsDirectory(LPTSTR lpBuffer, UINT uSize);
Look it up in MSDN for details.
The early bird may get the worm, but the second mouse gets the cheese.

If I declare it as
static extern int GetWindowsDirectory(ref string strDir, int size);
and call it as
string strDir = "";
GetWindowsDirectory(ref strDir, 20);
I still got the NullReferenceException.
The point is how to get the value back from the function.

You need to use the StringBuilder class instead of string.
StringBuilder strDir = new StringBuilder(20);
GetWindowsDirectory(ref strDir, 20);

Hai,
I wrote a windows service application using c#. I am able to install it using InstallUtil.exe provided by .NET framework. But I want to install the same service on a different machine which does not have .NET framework.
I think, InstallUtil.exe comes only when you install .NET (correct me if I am wrong). But I dont want to install .NET framework just for this utility.
Does c# provide any class which can be used to install a service? I read about ServiceProcess.ServiceController. But this only helps me to monitor the installed services.
Any suggestions...

Oops Sorry folks.
I read that you need .net framework to atleast run a .NET application ( no matter its a service or whatever ). So there is no way but to rely on InstallUtil.exe.
Thanks anyways

Can anyone tell me how to get the name of the computer (in which the code is running) using c#?
thanks.

Thought this one should do
String s = System.Diagnostics.Process.GetCurrentProcess().MachineName;

Ok. This is what I found out. I dont think there is a direct GetComputerName function in c# (as far as I know). Instead I read the following registry key
HKLM\System\CurrentControlSet\Control\ComputerName\ComputerName.
I hope this key is created in all machine because the System subkey stores sys related info.
If anyone wants to know the computer name, this is next to a good solution. Use, Microsoft.Win32 namespace for Registry related classes in c#.
One more thing "Naivete" and "omkamal" are one and the same. I just changed my username.
Thanks for your help.

You're right, it doesn't work on my system either. According to .NET documentation, MachineName property should return the name of the system
Gets the name of the computer the associated process is running on.

But if you read the document further it will also say that this property holds true only when you are trying to reach a remote computer...
Remarks
Specify a value for the MachineName property to view the processes running on another computer on the network. You can view statistical data and process information for processes running on remote computers but you ....

Sorry, I was obviously mistaken.
I guess you can try SystemInformation::ComputerName, as suggested in another post.

Try this:
string s = SystemInformation.ComputerName;

Awesome! Thanks Kelly. I appreciate your reply. I was so surprised how come c# doesnot provide such a functionality. But shame on me, that I felt so frustrating to check every single class for it. Nor did I try different search strings.
Thanks again,
Omkumar.

Sorry if I underestimated c#. Here you go. One more property to get the machine name...
System.Environment.Machinename

Will VS.NET require Product Activation like Windows XP ?
|
|
|
|

I did not install it yet, but it does not look like it will need activation, because a key is provided to MSDN subscribers.

How do I simulate downcasting in C#?
public class foo
{
}
public class bar : foo
{
}
foo f = new foo();
// The following line
// causes a run-time error.
// InvalidCastException
bar b = (bar)f;
************************
The following doesn't work either.
This gives a compile error.
public class foo
{
}
public class bar : foo
{
public bar(){}
public bar(foo f)
{ this = f; }
public static explicit operator bar(foo f)
{ return new bar(f); }
}
|

AFAIK that can't be done in C#. The 'foo' object never was a 'bar' object and can't be cast in that direction. A new 'bar' reference CAN be cast into a foo reference and then back into a 'bar' reference though.
You cannot cast this way in a strongly typed language. You may be able to do this in C++ (with reinterpret_cast) but the virtual tables will be messed up and strange bugs WILL happen.

Hi, I want to parse a mail from POP3.
Everything is OK except decoding a message.
For example, if I just mail to myself through a UNIX console,
I write a "Test" to Subject. i,e. "Subject: Test"
But through a Outlook Express or Other Mail Client Tool,
Subject is =?euc-kr?B?vNvAzsf... like this.
so, I must parse this encoded message. "euc-kr" is a encoding type?
then How can I convert this to UNICODE or just other type.
Please help me ^^;
