Generic replacement for Array.Copy?

Not unless the delegate has extra parameters

If I understand your question
No you cannot add extra parameters to system event handlers such as OnPaint or OnsizeChanged but you can on custom event handlers by adding extra parameters to the delegate.

Hi All,

I need to copy a subsection of an array to a List<>.

The only way i've found of doing this is to create a temporary array and do an Array.Copy(), as below:-

MyType[] srcArray = FillUpMySourceArray();
List<MyType> dstList = new List<MyType>();
int srcDataOffset, srcDataLength;

// declare temp array
MyType[] tmpArray = new MyType[srcDataLength];
Array.Copy(srcArray, srcDataLength, tmpArray, 0, srcDataLength);
dstList.AddRange(tmpArray);

I don't like the use of Array.Copy. Surely there's a better way?

I think this should work:

dstList.InsertRange (srcArray.Length, srcArray);

.NET 1.1 Wrapper For 2.0 Class

Hey guys.... I don't really know how to create a wrapper..... but I'd like to.

Anyhow, I'm writing a program in Visual Studio 2003, and I need access to a .NET 2.0 class. If I try to reference a .NET 2.0 assembly (dll) in Visual Studio 2003, I get the following error:

A reference to "C:\Slatesoft Development\utils.dll" could not be added. This is now a valid assembly or COM component. Only assemblies with the extension "dll" and COM components can be referenced. Please make sure that the file is accessible, and that it is a valid assembly or COM component.

Any help would be great. Thanks.

You can't use 2.0 assemblies in VS 2003

Okay, I figured that's what the problem was.

Is there any way to create a .NET 1.1 wrapper for the .NET 2.0 class?

No. YOU CAN NOT USE 2.0 CODE IN 1.1 ASSEMBLIES.

Newbie Inheritance question

When you inherited from a base case do you ALWAYS inherit all the functions and variables of the base class? I.e. If a base class has hundreds of variables and hundreds of functions do you inherit them all even if you don’t need them?

Thanks in advance.

You inherit them, but can only access the public, protected ones.

Hello,

I created a compiled c# dll. I need to know the path where this dll resides. I use this code to do it...

mstrStartUpDirectory = System.IO.Directory.GetCurrentDirectory();

When I call this dll from a c# windows app i get the correct path that the dll is in (C:\roto\Practice\MyClass)

When I call this dll from a c# web service i get the WRONG path that the dll is in (C:\Windows\System32).

What do I need to do to get the correct path that the dll resides in regarless of wether I am calling the dll from a Windows app, web service or whatever.

Thanks in advance

string path = System.Reflection.Assembly.GetExecutingAssembly().Location

This isnt working either. This returns the path to the .net framework. I want the path to the dll I wrote. I apprieciate your trying though.

have you tried finding the location of the object in the DLL?

Something like:
typeof(MyClassName).Assembly.Location

You're right. That's because the your web service is hosting the dll you wrote. Depending on what you're trying to do, one option is using your web service configuration file to store path information.
