string str = "this|is|a|test";
string[] arr = str.Split('|');

// arr == { 'this', 'is', 'a', 'test' }
// alternatively...

string str = "this|is,a|test";
string[] arr = str.Split('|', ',');

// gives the same result.

how to *easily* get virtual functions

hi,

this is more a question on working with vs.net;

back in the c++-vs6-days there was an easy way to get a list of all virtual (or base-class) functions and have an overwrite-corpus in your code with one click.

i wouldn't know about things like WndProc or IsInputKey if i wouldn't have this forum here. is there any way in vs.net to easily get a list of the available virtual functions and say "i want to overwrite this" with one mouse-click?

thx.

Hi!

If you higlight a class then there is a button on the properties window that lets you override base class virtual functions with one click!

i didn't find that button, but i found something else. if you walk the class-view tree into the base classes, there's an option "add-override" to each virtual methods contextmenu.

thx for your help. Smile | :)

O I didn't know that one! Thanks! But at least with c++ there's a button at the top of the properties window (when displayed while a class is highlited in class view) labelled ovveride (I have the german version of VS .NET) or similiar. It's next to the button where you create message overrides.

Using VS/.NET Framework with Minimum specs?

I have a computer with below minimum specifications for VS .NET (450MHz/128RAM + XP Pro). An upgrade is planned at the beginning of the next year.
Do you think I could run VS .NET somehow on this machine? (All I plan to do is to learn the .NET Framework)
Any tips are appreciated, thank you!

I run a PII 300 with VS.NET and it's fine.
Granted, it's got 192MB of memory, but I'm sure 64MB would be OK on a non-server and just running the framework.

So the VS.NET don't say "You don't have enough with mhz"? Smile | :)

But you need a WinNT system! I tried ínstalled it on a WinME computer...
It didn't allowed me to do that!

But WinME sucks anyway!

If you can afford VS.NET, I would urge you to at least get the memory up to 384 - 512MB, more if possible Smile | :)

I have 128MB RAM, and VS.NET, and my hard drive is swapping all the time.

My VS.NET experience is slowed. Often windows open in 5 seconds.

Plan to upgrade to 256MB.

Though I don't understand a sh*t who calls who in what you tell, you may look further with either of these :

- add a marshal attribute before the safearray param :

[Out, MarshalAs( UnmanagedType.SafeArray, 
                 SafeArraySubType = VarEnum.VT_RECORD )] out Object[] Items

See here[^]

- you may also implement a custom marshaler (ICustomMarshaler)

foreach Problem?

Paul Riley8-Sep-02 11:48

Paul Riley

8-Sep-02 11:48

Okay, I'm really confused. I have a foreach loop that looks roughly like this:

foreach(MyNamespace.MyDataSetType.MyRow row in MyDataSet.MyTableName)

Somehow the program is trying to retrieve one record past the end of the DataTable. That shouldn't happen, ever... right???

Has anyone else ever seen anything like this happen?

Paul

Re: foreach Problem?

Christian Graus8-Sep-02 12:01

STL iterators do this - a container has a begin and an end position and then can be stepped through by incrementing the iterator while it is < end. In other words, end is not a valid position. I'd say your dataset is doing the same.

Thanks Christian, it wasn't anything like that in the end, it was me being stupid.

While the loop appeared to continue, it was just escaping from the exception which was caused by the function WITHIN the loop. If it hadn't happened on the last record every time, I'd have noticed that sooner.

DOH! Frown | :(

Hi all,

Im REALLY new to all this and want to start programming. I want to start on either C++ or C#. My friends have told me to go for C# as it will be used more often in afew years and its easier to get started on and has good support.

The main question I have is C# good for gaming or any other program. As we all know chances of getting into the gaming field is low at the start. So what kind of job could I get in the begining using C# as my primary? Thats the biggest issue I have. I dont know what kind of job C# can offer me and if it is possible to code an game engine in it =) I mainly want to work on advanced AI code for games.

If C# is good then is it okay I get C# Standard? I really cant afford the 799 buck studio and it seems alittle stupid to get vb,c++,j when I want to start with C#. Also I noticed there is a book called C#, How to program is it any good?

Thanks in advance!

(im still new so if AI coding and such work on game engines with DX all work on any code dont laugh)
