Hi my name is vishal.For past 10 days i have been going nuts over of how to create barcode in c# windows forms with sql server 2008 using StrokeScribe control of version 4.3.2. i have done some coding here with 5 group boxes with no success. i have four group boxes
1) group box-1-name:fmeStep1,text:Step 1,visible:true.
It has 8 labels,2 comboboxes,3 textboxes,3 datetimepickers.
2) group box-2-name:fmeBarCode,text:"",visible:true
It has i label,i textbox.
3) group box-3-name:fmeDEntry,text:Dialyzer Entry,visible:true.
It has 2 radio buttons
4) group box-4-name:fmeStep2,text:Step 3,visible=true.
It has i textbox named txtDID,visible=true,enabled=true.1 button,1 strokescribe control of version:4.3.2.,name:barCDialyzer.Given below is properties of barCDialyzer:

Now here is the problem i am facing upon testing though entries process goes correctly till group box name:fmeStep1 afterwards i am not able get even controls of group box named:fmeStep2 and i dont know why? I want to see controls in fmeStep2 since in textbox named txtDID it shows me ID of Dialyzer that i am going to create and then in group box named:fmeStep3 i get to search for patient that i have to assign ID of Dialyzer to patient. I have tried fixing this problem many times but with no success. i am supposed to use StrokeScribe of version 4.3.2 only since it's my Boss orders and that i have to create barcode of type ean-13 in c# windows forms using StrokeScribe control with sql server 2008. Can anyone help me please where have i gone wrong in the coding. Can anyone guide me please. i was referred by Microsoft Developer Network community to ask my doubts regarding creation of barcode of type ean-13 in c# windows forms with sql server 2008. Can anyone help me please.?Any help or guidance would be greatly appreciated.

You should edit your message, it is almost unreadable as it stands. And try to identify exactly where the problem lies, rather than expecting others to work through code which they have never seen before.

what is northwind database and how to use it?

It's a sample database used in a lot of example code by Microsoft and others. You may use it as you wish to build code...

Northwind Database is a sample database that is shipped along with Microsoft Access application. Basically, the database is about a company named "Northwind Traders". The database captures all the sales transactions that occurs between the company i.e. Northwind traders and its customers as well as the purchase transactions between Northwind and its suppliers.
It's true, you could just have googled for "what is northwind database[^]"

Hello,
I'm collecting bitmaps from a camera like below:
private void LPRCamera2_OnNewFrame(object sender, ref Bitmap NewFrame)
{
while (LPR2List.Count >= LowCamSettings.LPR2FrameCount)
{
LPR2List[0].Dispose();
LPR2List.RemoveAt(0);
}
if (lpr2FrameIndex >= LowCamSettings.LPR2SkipCount)
{
LPR2List.Add(new Bitmap(NewFrame));
lpr2FrameIndex = 0;
}
else if (LowCamSettings.LPR2SkipCount > 0)
lpr2FrameIndex++;
}
I then take the list (LPR2List) and pass it to a new object that copies the list to a local variable. Like so:
for (int i = 0; i < LPR2List.Count; i++)
{
if (LPR2List[i] != null)
this.Plate2List.Add((Bitmap)LPR2List[i].Clone());
}
Every now and then i'm getting an error when copying telling me that the object is in use.
I haven't the slightest clue what I could be doing wrong. Any help would be greatly appreciated.

I suspect that this is a threading issue.
LPRCamera2_OnNewFrame appears to be an event handler and it may be raised on its own thread.
See this SO answer[^] for a good explanation.

I am new to programming and found a project online for designing a program that will randomly pull 4 cards from a 52 card deck. I want to prevent the same cards being repeated. I know there is a way to store it in an array to prevent repeating, just don't know how to do it. Any suggestions would be great.

The List type (List<PlayingCard>) will give you more flexibility. Use two lists:
List <PlayingCard> deck, drawn;
Where PlayingCard is the type for your cards.
When you draw a card, just delete that card from the deck list, and add it to the drawn list. It's as simple as that.
|
|
|
|
|
There are a few ways you could do this, but the simplest way is to store the cards in a list and then remove them when they have been selected. This isn't the best method to do this, but it is simple and easy to understand if you are new to coding. It's always best to start with the simplest solution that solves your problem.

There are a number of ways to do this, but the way I'd probably start is by creating a Card and Suit:
public enum Suit
{
Spades = 0,
Diamonds = 1,
Clubs = 2,
Hearts = 3,
}
public class Card
{
private int _Value;
public Suit Suit { get { return (Suit)(_Value / 13); } }
public int Value { get { return _Value % 13; } }
public Card(int value)
{
if (value < 0 || value >= 52)
{
throw new ArgumentException("Invalid Card : " + value);
}
_Value = value;
}
}
Then, it's a simple matter of creating the deck and shuffling it:
private List<Card> deck = new List<Card>();
private Random rand = new Random();
private Card GetNextCard(List<Card> deck)
{
if (deck.Count <= 0)
{
Enumerable.Range(0, 52).Select(c => new Card(c)).ToList();
deck = Shuffle(deck);
}
Card card = deck[0];
deck.RemoveAt(0);
return card;
}
private List<Card> Shuffle(List<Card> deck)
{
List<Card> shuffled = new List<Card>();
int cards = deck.Count;
for (int i = 0; i < cards; i++)
{
int index = rand.Next(deck.Count);
shuffled.Add(deck[index]);
deck.RemoveAt(index);
}
return shuffled;
}
Then just "peel off" the cards you want:
Card c1 = GetNextCard(deck);
Card c2 = GetNextCard(deck);
Card c3 = GetNextCard(deck);
Card c4 = GetNextCard(deck);

Write a C# program to simulate the drawing from a deck of 52 poker cards valued from 1 to 13 with 4 suits. One round of drawing consists of randomly pull any 4 cards from the 52-card deck. Therefore, the same card cannot appeared more than once. The program will perform 10,000 rounds of drawing and tallying the frequencies of the following possible results for the 4 cards pulled: (a)the 4 cards are having the same suit, (b)the 4 cards are from the 4 different suits, (c)the 4 cards are having the same value, (d)3 cards have the same value, (e)exactly 2 different pairs of 2 same-value cards, and (f)only 2 cards have the same value. Notice that (b) may occurred together with (c) - (f).
This is what I have so far:
using System;
namespace Draw4
{
class Program
{
static int[] ranData = new int[4];
static Random ran = new Random();
static int[] KS = new int[4];
static int GenerateRandomNum()
{
int cleanRanNum;
cleanRanNum = ran.Next(1, 53);
return cleanRanNum;
}
static void Main(string[] args)
{
int idx, ranNum;
int[] cdv = new int[4];
int[] cds = new int[4];
for (idx = 0; idx < 4; idx++) KS[idx] = 0;
{
Console.Write("Random numbers: \t");
for (idx = 0; idx < cdv.Length; idx++)
{
ranNum = GenerateRandomNum();
Console.Write(ranNum + ",\t");
cdv[idx] = ranNum % 13;
if (cdv[idx] == 0)
{
cds[idx] = ranNum / 13;
cdv[idx] = 13;
}
else
cds[idx] = ranNum / 13 + 1;
}
Array.Sort(cdv);
Console.Write("\nThe suits:\t\t");
PrintingSuits(cds);
Console.Write("\nThe values:\t\t");
foreach (int val in cdv) Console.Write(val + ",\t");
CountSuits(cds);
}
Console.Read();
}
static void CountSuits(int[] cds)
{
Array.Sort(cds);
int howManySuits = 0;
for (int j = 0; j < 3; j++)
if (cds[j] != cds[j + 1]) howManySuits++;
Console.WriteLine("\nThis hand has {0} suits", howManySuits + 1);
return;
}
static void PrintingSuits(int[] suit)
{
string s = " ";
foreach (int su in suit)
{
switch (su)
{
case 1: s = "H"; break;
case 2: s = "S"; break;
case 3: s = "D"; break;
case 4: s = "C"; break;
}
Console.Write(s + ",\t");
}
}
}
}

Ok, your method won't work to prevent numbers from repeating - which is why I created a list of Cards (but you could use int values instead). If you uncomment the line adding the card back to the bottom of the deck, you can simply have a loop which grabs the top four cards, prints them, and then calls the Shuffle method. It can then loop 10,000 times without problems.
The advantage of using a Card class is that it moves the complexity out of the "main" code: you can tell the Card to print itself, by adding a ToString override that returns "4 of Hearts" or "Ace of Spades" and just call Console.WriteLine:
for (idx = 0; idx < cdv.Length; idx++)
{
cdv[idx] = GetNext(deck);
Console.WriteLine(cdv[idx]);
}
So you main method consists of a little init code, then a loop, which calls shuffle, and then does the loop above.

Okay so I have gotten the random numbers to stop. What about the conditions A-F? I know what I want to say, problem is how to say it and where to say it if that makes sense. Sorry if these noob questions are tedious. Just trying to learn.

(from my Windows Phone)
make some variables for the statistics you need, unit to 0
write a for loop for the 10,000 iterations
inside, shuffle the deck and draw 4 cards (1st 4 will do)
for each of the statistics check for the condition and increment the appropriate counter variable if true
after all 10,000 iterations, compute the frequencies and report them.

You could build it even simpler then a list.
bool [] deck = new bool [52];
the index is the card you draw and true is drawn, false is not drawn.  .
A little more complex is to create a class Card which holds a boolean "drawn".
I personally only use Lists (and other collections) on dynamic arrays (those that can grow/shrink) and arrays on static arrays (like this case, because there are always 52 cards in a card game. This is just personal and there is nothing wrong in using a list.

Hey Guys,
Am a beginner to C# Programming, i have a requirement to create a smal project.
The project is to track the no of task done by individual. Few descriptions below.
1. Once a person is assigned with a Task, he need to enter the same in the front end tool.
2. This data will be getting captured in the backend (e.g: sql database) like Task#, Task Name, date, person name.
3. On completing the task, the person will enter the details in the tool.
4. So in the database we have the details for
a) No.of task done by induviual (e.g; in a month)
b) time taken to complete the task etc.
Planning to create front end of the tool in C#
Backend in SQL.
This frontend tool will be installed to all the users (e.g: 50 machines)
and the SQL server will be on Manager's machine, so that he will pull the report daily to see the status of the task assigned.
Planning to create the tool in Client-Server model.
is the above tool be done with visual C# + SQL ?
My Queries:
1. When i use windows application in C#, on linking the SQL database am hardcoding the SQL server details (e.g: i harcode Machine1\SQLEXPRESS ) but if at all am changing the server in future to Machine2\SQLEXPRESS do i need to recompile my Code again ?

Yes you do. If you have hard coded the value you would have to change the value in code and recompile it. A better bet is to use configuration to store this value - in your case, you would want to store this in the ConnectionStrings section in app.config. This way, you only have to change the value in the config file and you will be able to run it against the new SQL database without recompilation.

Pete O'Hanlon,
Thanks for your quick reply,
Reply: "you would want to store this in the ConnectionStrings section in app.config"
So when do i need to do this, when am establishing a connection between SQL and my windows application ?
when i make the changes to app.config file with new server details, then i need to make sure that all users have the newly updated configuration file in on their machine.
1. So in this case, is their any option for creating a patch.exe to be installed on the machine which will replace the old config file on users machine to newly updated config file. ?
2. And regarding the front end tool using windows application, my requirement is to have a 2 flavours of tool.
a) one installed to all the users (e.g: 50 machines) this will have only limited options to only enter data of their tasks.
b) another one is the Admin tool , with extra options and dialog boxes and buttons to pull daily or monthly data in form of excel from SQL server.
How this can be done ? please assist.

Yes you will need to recompile, as the connection string is part of the program. You should take a look at the ConfigurationManager Class[^] for ways of managing this information.

1. For the connection strings, take a look at Don't hard code your DataProviders[^], which explains how it should be done. I'm not sure how you deliver updates for an installed application, try searching for articles on the subject.
2. I don't see a problem, just create a separate tool for administrator use, or add some sort of password login to it.
