Wow - is that worth something in parts of the world ?
I wouldn't have given the answer, because all you're doing is teaching this person to not do their own homework. I hope he ends up working in the cubicle next to you and not near me.

Just adding a little, virtual methods can be overwritten in a derived class (by using overwrite keyword) but is not mandatory. Also you can have a method with the same name as the one in a parent class and hide it with a technique called shadowing (by using new keyword).

In my current project I want to replace a library I'm using by an other one I will write my self.
1st I want to write a skeletton library which feature all type/method I'm using (with no real code inside).
For that I would like to go through my project, track every library object I'm using and all the method I'm calling and create a mock-up library where I would define all the types and and methods I'm using from the 3rd party lib.
The thing is I would like to do it automatically through someting like reflection.
Is there a way I could do that simply? Any tips or links?
Here is an example, current code below
class MyProject
{
void AMethod(ALibObject1 obj)
{
obj.Method1();
ALibObject2 o2 = obj.Method2();
o2.Method3(new LibObject3());
}
}
I want to go through the code (or probably compiled assembly) above (automatically), by using reflection on the assembly (or something similar) and produce:
public class ALibObject1
{
public void Method1() {}
ALibObject2 Method2() { return null; }
}
public class ALibObject2
{
public void Method3(LibObject3 obj) {}
}
public class LibObject3
{
}
Any tip on how to do that simply in an automated way?

Hi,
After I copy and paste some excel cells into a richTextBox in window form, how can I edit the excel data in the richTextControl, so that it can reflect the changes back in the excel source ?
Thanks

Hi!
If you simply paste Excel cells into a RTB, they're pasted as a RTF table without any information that the cells have been put into the clipboard from a certain Excel sheet. So there is no way back.
You're out of luck here, sorry.
Regards,
mav

I have an array of letters which’s makes a word and I was wondering how I could compare a user’s input letter against the letters in the array so when running it would display something like this
Example
** Word to be guessed in array – train **
User inputs letter a
Displays _ _ a_ _
User inputs letter n
Displays _ _ a _ n
User inputs letter t
Displays t _ a _ n
And so on until the word is complete.
If some1 could provide an example I could follow id be most grateful as I purchased a book a few days ago on c# programming and this is one of the tasks it doesn’t really give much info on how to do it. i know it uses a loop to move along and check each character but im not sure on this.
thanks

It is a common misconception that learning to program is "equal" to learning a programming language. Evidence of it abounds here in these forums. Anyway, you need a book on Programming Logic and Design[^].

I've enabled drag/drop on several ListBoxes via the MouseMove event. When I call MyListBox.DoDragDrop(...) from the event however the SelectedIndexChanged event doesn't always fire, and the various ListBox.SelectedFoo properties do not update. I can get the selected items for the drag/drop action by calling the GetSelected method for every item in the listbox, but having to do so is an ugly hack.
More seriously, I can't safely manually call the method I have attached to the SelectedIndexChanged because if the event has never fired normally, trying to access the SelectedIndex property returns an IndexOutOfRangeException. If I comment out the call to DoDragDrop, this problem never occurs so I know somehow it's responsible for what's going on.

I've partially kludged around this by setting SelectedIndex at the same time as I'm using the GetSelected Method to check which items are selected to generate my drag/drop event.
This appears to fix the problem about 99% of the time. Occasionally however, while doing a series of very frantic clicks on the list I manage to get two items shown as selected in the UI even though clicking on one should automatically clear the selection on the prior item. When this happens, I'm still having my SelectedIndexChanged event fire with the SelectedIndex property filled iwth an indexOutOfRangeException. When looking at the returns from GetSelected in the debugger, only one of the two items that appear selected in the UI are returning true.
The listbox is using the multiExtended selection mode, so it shouldn't be possible to select multiple items with hte mouse at all.

Hi All,
I have a c# form for the user to fill in the registration info. However, the user will get Syntax error (missing operator) in query expression when he fill in the form with "'s" or "<%" or "<#". I am using Regex.Replace(textbox.Text, "'", ""); but I need to save the "'s" in DB. I would like to know if there any solution for this issue? Thanks in advance.

This is because the values are being "injected" into the SQL Command. A very bad practice that leads to innumerable security failures for your database.
Read this article[^] it will tell you exactly why you are getting the problems you are getting and exactly how to fix it.

Since I am new to database, I want to know how to approch that.
Assume that I have a table, I call it table A with the follwoing fields
A | B | C | D
==================================
Now, table A will take value from the fields like
[A1], [B1], [C1], D[1] etc.
Given that for each value added to field A, I want to create another table. For instance, for the above example, I will have a table A1 with fields like
A11 | A12 | A13
===============
The same for A2 etc.
The way to look at it, for each value added to field A of the original table, I want to have another table. I want to know if this is the best way to do it. I couldn't find any other way.

If the relation is 1 to n then it is ok
Each item of table B would have an index refering to Table A item.
But if it is an n to n relation, then you should have your two tables (A & B) and then a Table C with A & B indexes.
Hope it helps.

Only the value from field A determine the next table that will be created. I think this is a 1:n

Creating multiple tables in this scenario will hurt the managability of your database. You can do it if you want, but it would create more problems than it solves.
