Great subject. What does that mean?
Same goes with the post. Be descriptive and adhere to the rules.

You might get a better response from the Amzi Support Forums here[^].
I would try there, if I were you. Come back here if you get no joy there.

1. Why on C# forums?
2. Why not on algorithms forums?
3. Why that looks like homework / contest?
4. What's the problem?

You do realise you are feeding a troll right!

Hey, I am trying to write get/set properties for an array
public class MyClass
{
private MyType[] MyArray = new MyType[10];
public MyType this[int index]
get
{
return MyArray[index];
}
set
{
MyArray[index] = value;
}
}
but when I use code like this
MyClass instance = new MyClass();
instance[index].MyProperty = " ";
I get a NullReferenceException, can anyone tell me what is wrong with this code?
Thankyou

Maybe constructor of your class (MyClass) is not filling array with "MyType" (which is a class)? So instance[index].MyProperty == null , and you are referencing to it.
|
|
|
|
|
Yes, "MyType" is a class.
In the constructor I have MyArray = new MyType[arraySize] is that what you mean by "filling the array"?
|
|
|
|
|
You create array of references, without creating objects, so what you get is array full of null references. Then you are refering to one of this object, which generates NullRefException.
|
|
|
|
|
If that is all, then MyArray will just contain 10 nulls.
|
|
|
|
|
Yes, it makes sense now.
Thankyou

I'm trying to obtain the path of the file(s) that o certain process reads from or writes to (similar to the way Performance Monitor does in Vista).
I couldn't find out any direct method neither using WMI (Win32_Process class), nor the Process class from
System.Diagnostics.
Thank you.

Thanks for the reply, Giorgi.
I've managed to find a way to obtain file handles for a process. Here is the code:
[DllImport("ntdll.dll", SetLastError = true)]
public static extern uint ZwQuerySystemInformation(SYSTEM_INFORMATION_CLASS SystemInformationClass, IntPtr SystemInformation, int SystemInformationLength, out int ReturnLength);
[StructLayout(LayoutKind.Sequential)]
public struct SYSTEM_HANDLE_INFORMATION
{
public int ProcessId;
public byte ObjectTypeNumber;
public byte Flags;
public short Handle;
public int Object;
public int GrantedAccess;
}
public const uint STATUS_INFO_LENGTH_MISMATCH = 0xc0000004;
public static SYSTEM_HANDLE_INFORMATION[] EnumHandles()
{
int retLength = 0;
int handleCount = 0;
SYSTEM_HANDLE_INFORMATION[] returnHandles;
int allocLength = 0x1000;
IntPtr data = Marshal.AllocHGlobal(allocLength);
while (ZwQuerySystemInformation(SYSTEM_INFORMATION_CLASS.SystemHandleInformation, data,
allocLength, out retLength) == STATUS_INFO_LENGTH_MISMATCH)
{
data = Marshal.ReAllocHGlobal(data, new IntPtr(allocLength *= 2));
}
handleCount = Marshal.ReadInt32(data);
returnHandles = new SYSTEM_HANDLE_INFORMATION[handleCount];
for (int i = 0; i < handleCount; i++)
{
returnHandles[i] = (SYSTEM_HANDLE_INFORMATION)Marshal.PtrToStructure(
new IntPtr(data.ToInt32() + 4 + i * Marshal.SizeOf(typeof(SYSTEM_HANDLE_INFORMATION))),
typeof(SYSTEM_HANDLE_INFORMATION));
}
Marshal.FreeHGlobal(data);
return returnHandles;
}
Then I'd like to obtain the handles for a specific process:
SYSTEM_HANDLE_INFORMATION[] handles = EnumHandles();
var winampHandles = from handle in handles
where handle.ProcessId == 10004
select handle;
foreach (var winampHandle in winampHandles)
{
}
As we can see, each handle is an object of type SYSTEM_HANDLE_INFORMATION, which does not contain a field specifying the name of the handle. To obtain the name of the handle (e.g. the file path), I think I need to call some Win API.
MSDN has an example of how to to this: http://msdn.microsoft.com/en-us/library/aa366789(VS.85).aspx[^], but it is written in C, and I need it for C#.
Is there some other way around this thing? I've tryed using the FileStream class, and pass to it's ctor the handle:
FileStream fs = new FileStream(new IntPtr(winampHandle.Handle), FileAccess.ReadWrite, false); , which throws an IO Exception ("Invalid handle"). Passing a SafeFileHandle to the ctor didn't solve the problem.
Any ideas?

Hi, I am sorry for some earlier posts as i was bit confused on my design of application...
Ok..I have BillDetails,Products,Packing Table...
And on winform I have gridview...Now in gridview I want to display billdetails table..but somehow the first two columns need to be combobox..and these combobox should take data from Products Table together with Packing..
I have screen shot as what exist in those tables..Also below is a small code that i have done but i see only one dropdown list with nothing populated...
Please HELP..I will really appreciate as i am stuck in it for few days
:confused:void fillData()
{
OleDbConnection database = new OleDbConnection(connectionString);
database.Open();
OleDbDataAdapter adapter1 = new OleDbDataAdapter("SELECT BillDetails.ProductID, BillDetails.ProductName, BillDetails.InQty, BillDetails.InBns, BillDetails.InPrice, BillDetails.Dis1, Products.packing, BillDetails.Saletype, BillDetails.SBtype, Products.FactorC, Products.FactorB, BillDetails.Type FROM Products INNER JOIN BillDetails ON Products.ProdID = BillDetails.ProductID", database);
DataGridViewComboBoxColumn dgridcolumn = new DataGridViewComboBoxColumn();
dgridcolumn.Name = "Products";
this.dataGridView1.Columns.Add(dgridcolumn);
DataTable dt = new DataTable();
DataTable packDT = new DataTable();
adapter1.Fill(dt);
dataGridView1.DataSource = dt;
adapter1.Fill(packDT);
dgridcolumn.DataSource = packDT;
dgridcolumn.ValueMember = packDT.Columns[1].ColumnName.ToString();
dgridcolumn.DisplayMember = packDT.Columns[1].ColumnName.ToString();
}
