Dang, is that a Mercury or Venus second (or worse, 1/60 of a New York minute)? I swear I just posted that and almost immediately got a popup from MSN Messenger about a new email from you!

Hey. How do you make MSN do that? I bet it's just an Express thing...

You just have to have a MSN or Hotmail account and use that email address (which is automatically a Microsoft Passport) to sign-on to MSN Messenger. You can also do this with Windows Messenger with the MSN Add-in (available somewhere on Microsoft's site - I just don't use the latter version of IM because it doesn't advance near as quickly).

A priority queue can be implemented easily in C# by wrapping the SortedList class. Since inserts and deletions into the SortedList are O(n lg n) operations then it won't be a very efficient implementation, but if the queue only holds a few objects then this probably won't be a problem. If you are needing an efficient implementation then you'll have to write your own from scratch using heaps or binary search trees.

How to disable on word window Title Bar, StatusBar, Minimize, Maximize, CloseButton, SIzable and Movable?

when i include more than 1 user defined header file eg
#include "tcplib.h"
#include <stdio.h>
#include <iostream>
#include "big.h"
tcplib.h and big.h..... the second header file doesnt include in that it gives me errors saying its not included, any ideas on how to solve this? are you able to include more than one user defined header file?

Well, now that goes without saying, right ?
I recently discovered that Array has static functions for sorting and so on. Nowhere near what the STL has, but at least it's something.....

I find it interesting to use Reflector[^] and just go through the namespaces and pick a class to see everything. The Marshal class in System.Runtime.InteropServices is my current read, when I have free time that is.

Nope - and I use it too. It's such a help to be able to see exactly what will happen when you call a certain method or property.

I want to make a function unaccessable in a child class (that's public in the parent class)
The parent class has:
public virtual void ShowPopup(System.Drawing.Point p)
I tried doing this in the child class:
private override void ShowPopup(System.Drawing.Point p)
The compiler compains that I can't make a virtual function private
Any ideas how I could hide this function?
Thanks,
Elena

The compiler is right because private means that only the class that has the method/property/field can use it. No other class is permitted access including any class derived from it. And virtual tells the compiler to expect derived classes to override it. Therefore making a method private and virtual would be utterly pointless.
Hiding the method kind of goes against the grain of Object Orientation. I remember years ago my OO lecturer at University going on about that. When you create derived classes you are creating specialisations of the base. You should never be taking anything away from the base, just adding new methods and specialising existing ones.
I would suggest that you re-examine your class design and work out if there is a way to better design the classes so that you are not having to take away the functionality in the base.
Alternatively you could explain a bit about your design and maybe some people here can help you re-work it.

Thank you for your replies.
The reason why I want to hide the parent class is because I need more data for the child.
By the way the parents class is built in, I can't change it: DevExpress.XtraBars.PopupMenu
I want the user to call the following function that is implemented by the child
public void ShowPopup(System.Drawing.Point p, File selectedFile, Folder selectedFolder, Folder destinationFolder)
instead of the original
public void ShowPopup(System.Drawing.Point p)
I could have two separate calls: SetFileData(selectedFile, selectedFolder, destinationFolder) and then ShowPopup(p), but there will be big bad problems if the user forgets to make the first call.

I assume by "user" in this case you mean another "developer". To avoid confustion, I'll use the term "developer" to mean a person that writes code, and "user" to mean a person that uses software applications.
Okay, so you have a third party component that exposes a method called ShowPopup(), you want to derive a class from it and extend the functionality by implementing your own ShowPopup with extra parameters. In the new derived class the base.ShowPopup() will work correctly so long as the developer has called SetFileDate(). Right?
My advice is to not mollycoddle other developers, defend against users doing weird things but not developers. Document that there is an extended version of ShowPopup() with the extra parameters which is to be used in preference for this class. Also document that if the original ShowPopup is used that the SetFileData() must be called first for this class. Anything else is wrong and will cause an exception to be thrown (remember that is what exceptions are for).
Here's an example of something designed in a similar way to what I've described: What happens if you have an array with 5 elements and you try and get the 10th element? An exception is thrown. Why? Because that was a dumb thing to do.
If it helps, you should override the ShowPopup() [You mentioned it was virtual already] and check for the prensence of the file data and throw the relevant exception if it doesn't exist. (If you don't have a relevant exception, create a new exception class)
Begin Rambling Nostalgia: I remember back in the days where I did C++ development the documentation was full of remarks like "The first parameter takes an integer between 1 and 12, for any other supplied value the results are undefined". In other words, "Garbage In, Garbage Out". In reality the "undefined" results could mean anything from invalid calculations to the whole application crashing. At least now there are exceptions so that invalid/missing inputs or expected preconditions can be thrown out and dealt with properly.
I hope this helps.

You can't make a public function in a parent class private in a child child class. if you could, it would break polymorphism since the inherited class would not support the parent's "interface" or contract. What you can do is override ShowPopup so that is does nothing.
