How to declare external lib in C#?

Hi there,

I would like to retrieve the computer name in C#, here is the piece of code
in VB:

Private Declare Function GetComputerName API Lib "kernel32" Alias
"GetComputerNam eA" (ByVal lpBuffer As String, nSize As Long) As Long

How do I translate to C#? thanks!

[DllImport("kern el32", EntryPoint= "GetComputerNam eA")]
private static extern int GetComputerName (StringBuilder lpBuffer, ref int
nSize);

Hi. Use System.Environm ent.MachineName instead.

I believe this is the one you wanted to use

[DllImport("kern el32.dll")]
static extern bool GetComputerName (StringBuilder lpBuffer, ref uint
lpnSize);

http://www.pinvoke.net/ is a great source of WinAPI - C# related
information, check it out.

In general, you can go to

http://pinvoke.net/

to find many Win32 declarations. They look a lot like VB6.
GetComputerName () is at

http://pinvoke.net/default.aspx/kern...etComputerName

Noob problem. I prefer to keep all my scripts in an external '.js' file. I am currently loading the external '.js' file from the header. Problem is I would like to declare a global variable in the external file, but I keep getting an error about the object does not exist. Can someone tell me where or how to declare a global variable in an external file that is available after the page is loaded.

According to my programming textbook, "int a;" at the top level of a file is a definition which shouldn't go in a header file. However, I'm running into a lot of online documentation that treats that kind of statement as a declaration that can be in a header file used in multiple compilation units. Which of these is correct? Is this something that has changed between different standards?

Notice below I sometimes used the "A" version. I found by cut-and-try that only the "A" version would work correctly. Anyone have a suggestion of why the "W" version would not work correctly? One reason is that the ByRef or ByVal does not show by InteliSence so the "p" would help there. ------ Secondly, I'd like to be consistent with the parameter names. I'd like to

I was thinking of buying Scott Meyer's second book (More Effective C++) and noticed that it has not been updated since 1995 (unlike his other two famous books). Does anyone know (rumour or otherwise) if a new edition is coming out. I would hate to spend $50 today only to see a new edition on the shelves tomorrow.
