How to make, shuffle, and deal a deck of cards in C# .NET 2003
Hitekrednek
to make a card game similar to a three-card monty in which the user
guesses where the Ace of Spades is. I noticed during the time we
spent coding that most of the students in the class required help from
either myself or our teacher to understand how to make the cards work
correctly. I had to do quite a bit of googling to find the images I
wanted, but being a hacker/programmer before I stepped foot into
college meant that the assignment wasn't that hard for me. I neary
wasn't able to turn it in, however, because my classmates constantly
needed help, and, being the good semaritan that I am, I couldn't turn
them down. So, for all the other programmers here on the interweb, I
am now going to post the code to make a simple gui, and deal four
cards from a real shuffled deck at random onto the screen. I also
tried to comment it as well as I could to ensure that students and
autodidects alike can understand what I did here. Enjoy.
[code]
/*note, the cards I used were obtained from http://www.jfitz.com/cards/
They can be downloaded directly from the website and come named 1-54
for ease of assignment while coding. The owner of the images gives
them away free, with all needed information. The main knowledge
needed for this programming example is that of arrays. Arrays are
strings of integers or some other datatype. They can be amazing
resources for things like cards and other multi-piece objects, like a
puzzle. Feel free to use this code as you wish, as long as you don't
somehow use it to like me to some sort of criminal activity, and I am
not responsible for what you do with this code./*
/* The main point of this program is to show beginning programmers how
to make, shuffle, and deal a real deck of cards for a game. This
program will work for all games programmed in Visual C#.NET 2003 and
any years that it may be further compatibe. Please enjoy and feel
free to use it in any of your programming needs.*/

run as is. There are several spacing mistakes, a few comments that
need to go from // to /* */ and one capitalization error on the word
"Information" in the MessageBox.Show statement. If you would like me
to post the corrected code, please let me know, but I don't want to
flood the place with code just to make a few small corrections.
again, enjoy the code.
oscarjaime
I did the same and getting the same
can you post the correct code please
Also I'm in a middle of card game project for the church
I'm learning my self VS .NET & Powerbuilder
Can you tell me how can I start these project from the scracth
I'm little disoriented
Thank you - Oscar
Hitekrednek
project, and form. The only corrections that must be made with the
code are listed in my short post below it. Paste the code I've posted
into the form. Check all of the comments to be sure they're properly
opened/closed, as I added some of them while posting this, and some of
them are wrong, and fix the capitalization error in the
MessageBox.Show statement. When that's done, you should be able to
just compile and run the program. You can use the break/step feature
to see how the code works line by line as it runs.
You can email me at jdiamo...@gmail.com for any further
assistance, and that goes for any and all who need help with similar
situations. I am not currently able to afford my own internet
connection, and am not on often, but I try to check/respond to
everyone who writes me asking for help, unless they have a close
deadline and I miss it. If that happens, I'm sorry.
I am not familiar with powerbuilder, so you'll have to seek
assistance elsewhere for that, but I'm open to all VS.NET questions.
Also, obviously, this code is just to build the core of the
cards' operation. There are many other features that could be added
to the dealing process and such, and there are also an infinite number
of rules that could be formed to make various different card games
around this code, and would only require slight changes to the form/
number of cards dealt.
I hope that helps, and don't hesitate to ask for help when
needed.
