Hi everyone,

I am planning to make a Texas Holdem Poker game in VB. I am looking forward to some basic application where five card are selected at random and displayed on the screen and then users will have their two card in their hand (physically). Then the application will ask the users to enter their cards in hand and then the system calculated if they have won or not.

I have some idea about the basics like I will need 2 classes one for cards and one for the deck and two methods, one for shuffle and one for deal.

I also have all the card images etc available.

But before starting I was wonder if I could look at some sample codes. I am not sure where to start from.

Any help to guide me in the right direction will be highly appreciated.

Thanks

- Define a deck of cards as a 4*13 2D boolean array, and a card object as a two integer pair.

- As you randomly generate a card (S=rand(1,4) for suit and V=rand(2,14) for value), you mark the appropriate array index Deck[S-1][V-2] = true, and on future random generations, ensure that the card has not already been drawn)

- Have a function that sorts your hand as you did, and then checks for hands from highest to lowest value based on flush, straight, pair determinations. As soon as a winning is found, you can break and return the appropriate multiplier.

- When you create a hand, you should sort it in ascending order. A hand can be easily defined using two 5 element arrays. One array of face values (where 2=2, 3=3, ..., Jack=11, Queen=12, King=13, Ace=14). The other array is the suits (which can just be a single character or a number from 0 to 3)

bool flush = true;

for( int i = 0; i < 4, flush == true; i++)

if( suitArray[i] != suitArray[i+1] ) flush = false;

//We assume a flush until a test tells us otherwise.

bool straight = true;

for( int i = 0; i < 3, straight == true; i++)

if( (valArray[i]+1) != valArray[i+1] ) straight = false;

if( straight == true && (valArray[3]+1) != valArray[4] && (valArray[3]+9) != valArray[4]) straight = false;

//Because there's a special case for a wheel straight the final test is done after the loop.

int pairCount = 0, matchCount = 0, maxMatch = 0, maxPair = 0;

for( int i = 0; i < 4; i++)

{

if( valArray[i] == valArray[i+1] )

{

if( matchCount == 0 ) pairCount++;

matchCount++;

maxMatch = matchCount > maxMatch ? matchCount : maxMatch;

maxPair = valArray[i] > maxPair ? valArray[i] : maxPair;

}

else

matchCount = 0;

}

if( straight == true && flush == true && valArray[0] == 10) //return Royal Flush

if( straight == true && flush == true) //return Straight Flush

if( maxMatch == 4) //return Four of a Kind

if( pairCount == 2 && maxMatch == 3) //return Full House

if( flush == true ) //return Flush

if( straight == true ) //return Straight

if( pairCount == 1 && maxMatch == 3) //return 3 of a Kind

if( pairCount == 2 && maxMatch == 2) //return 2 Pair

if( pairCount == 1 && maxMatch == 2 && maxPair >= 10) //return High Pair

Hope that's a solid start. Good Luck.

Deck - 52 cards. shuffle will be a randomize function, put them on a stack or in a list randomly so that all 52 are contained.

Deal as per the rules, just taking off the front card and allocating it to the person.

If you are going to give them physical cards . . . what's to say I don't have aces all the time? What's the finaly application?
