Hi all,
maybe you'll see the trick and could help me. I am passing int by
reference and get an exception when using it as an index to passed
array. (Yes I know I can workaround with object encapsulation, but
wish to understand this). Thanks, Jan
[code]
using System;
public class TestPassByRef {
public void printArray(stri ng[] a) {
p = new int(0);
printArray(a, ref p);
}
private void printArray(stri ng[] a, ref int p) {
if (p < 0 || p >= a.Length) return;
Console.Write(" {0}:", p);
Console.Write(" ({1}) ", a[p]); // here it breaks .. see output
below
p++;
printArray(a, ref p);
}
}
public class Test {
static void Main() {
string[] a;
TestPassByRef t = new TestPassByRef() ;
a = new string[] {"A","B","C","D ","E"};
t.printArray(a) ;
}
}
[output]
0:

In an attempt to answer another question in this group, I've had to resort
to calling the DOM method, Node.removeChild(), using a reference to it
(long story...). That is, passing Node.removeChild.
In Opera (7.23/Win), the call appears to do nothing - the node remains -
but no errors are shown. In Netscape (7.0/Win), an exception results.
On IE (6.0/Win), the node is removed.
Strangly, if I pass another function reference, say...

Hi,
I am writing a simulation package in C++, and so far I've written about
8000 lines of code and have about 30 classes. I haven't used C++
exceptions so far (for various reasons). The only two "resources" I use
are memory and file I/O and whenever there is a memory allocation
failure or file I/O failure I just simply call a custom assert-type
function to check, print a error message and abort. This seems to be OK
for now (for the...

I am wondering if there are some best practices for determining a strategy
for using try/catch blocks within an application.
My current thoughts are:
1. The code the initiates any high-level user tasks should always be
included in a try/catch block that actually handles any exceptions that
occur (log the exception, display a message box, etc.).
2. Low-level operations that are used to carry out the high level tasks

I'm having a problem with a mixed managed/unmanaged DLL. When I

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
