I have a list that consists of 'customer'-objects. Every 'customer' has a full name, address, email, and phone. Now I want to be able to do a search that lets the user type in information in a form and then perform a search based on the information the user typed in. In the form the user can type in 'first name', 'last name', 'address' and so on.
But how do I compare the information the user types in with the information stored in the 'customer' objects? If the user only types in the 'first name' and 'phone' for example the search must pick out all 'customers' that matches that.
Thanks for help!

So, you go through all your objects, and you match all with the same first name, and phone, if that's what they typed.

Maybe you can modify this a bit to suit your own needs. I am searching on one given string in a text box and pull all data in the DB to a listbox.
private void btnSearch_Click(object sender, EventArgs e)
{
FillListBox(textBox1.Text);
}
public void FillListBox(string searchValue)
{
try
{
dataTable.Clear();
DataAdapter =
new OleDbDataAdapter
("Select [PicId], [Path] From [Pics] WHERE PicId = '" +
searchValue + "'", conn);
DataAdapter.Fill(dataTable);
listBox1.DataSource = dataTable;
listBox1.DisplayMember = "Path";
listBox1.ValueMember = "Path";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
}
Excellence is doing ordinary things extraordinarily well.

Thanks for your replies.
I came up with a solution that worked well but I don't know if it's optimal:
I search through all the information stored in each customer in the list. If the information in the customer object matches the information the user typed in the textbox the result is stored in a new list. If the information in the search textbox is empty it's also seen as a match. See below:
public int[] SearchCustomers(Customer searchCustomer)
{
//Create list for search results.
searchResult = new List<Customer>();
//Loop through all information in the customer-objects.
searchResult = customers.FindAll(delegate(Customer C) { return SearchFirstName(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchLastName(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchCity(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchCountry(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchStreet(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchZip(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchCellPhone(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchHomePhone(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchEmail(C, searchCustomer); });
The final result is a list containing the matches of all search words.

You can use J# for that, or you need a third party component.

hello
This scripts runs okay on SQL*Plus and TOAD (using same account "dev") but not sure when I try to wire it down through "System.Data.OracleClient" I keep getting the following error:
<br />

END;<br />
As you can see, the script is anonymous block taking no argument
And I looked at the code, can't see anything wrong.
<br />
oCmd = oConn.CreateCommand();<br />
oCmd.CommandText = DBUtil.FixParameterNameForOracle(oContext.DefaultDBProvider, StringUtil.ReplaceSpecialTokens(SQL));<br />
oCmd.CommandType = System.Data.CommandType.Text;<br />
<br />
oDataSet = new DataSet(CmdFilePath);<br />
oTable = new DataTable(Name);<br />
oDataSet.Tables.Add(oTable);<br />
oAdapter = oFactory.CreateDataAdapter();<br />
<br />
oAdapter.SelectCommand = (DbCommand)oCmd;<br />
oAdapter.Fill(oDataSet, Name);<br />
oCmd is of type "System.Data.OracleClient.OracleCommand". And it takes no parameter or input argument. I googled a bit closest I found is this:
http://social.msdn.microsoft.com/Forums/en-US/adodotnetdataproviders/thread/579b5a98-ec74-4f6f-b5b4-6919d8bc3e7c/[^]
But my script contains no parameter.
Also, using "oCmd.ExecuteNonQuery()" instead of dataAdapter.Fill didn't help. I finally found one get around (NOT A DECENT SOLUTION!), that is to collapse the multiline script to single line!
<br />
DECLARE count_item int; BEGIN SELECT count(1) into count_item FROM user_sequences WHERE sequence_name = 'AUDITLOGSEQUENCE'; IF count_item > 0 THEN begin dbms_output.put_line('drop sequence AUDITLOGSEQUENCE'); EXECUTE IMMEDIATE ('DROP SEQUENCE AUDITLOGSEQUENCE'); end; ELSE dbms_output.put_line('no need to drop AUDITLOGSEQUENCE'); END IF; EXECUTE IMMEDIATE 'CREATE SEQUENCE AUDITLOGSEQUENCE MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 INCREMENT BY 1 CACHE 20'; dbms_output.put_line('AUDITLOGSEQUENCE created'); SELECT count(1) into count_item FROM user_tables WHERE table_name = 'LOG'; IF count_item > 0 THEN begin dbms_output.put_line('drop table LOG'); EXECUTE IMMEDIATE ('DROP TABLE LOG'); end; ELSE dbms_output.put_line('no need to drop table LOG'); END IF; EXECUTE IMMEDIATE 'CREATE TABLE LOG (Id numeric(19,0) NOT NULL, CreateDate date default sysdate NOT NULL, Thread varchar (255) NOT NULL, LogLevel varchar (50) NOT NULL, Logger varchar (255) NOT NULL, Message varchar (4000) NOT NULL, InnerException varchar (2000) NULL,CONSTRAINT PK_LOG PRIMARY KEY (Id))'; dbms_output.put_line('table LOG created'); dbms_output.put_line('setup complete'); END;<br />
What the hell!? I have a big script next and I'm really not impressed ... any suggestion besides this?
Thanks

found it... I fixed strSQL from application, removing all instances of newline
strSQL = strSQL.Replace('\n', ' ');
I'm very impressed by the work on System.Data.OracleClient, some quality code!

I tried to list drives available in a system in checkedlistbox.When i click on the C:\ i want to list its files in a listview.I tried with the following but it does not work.Can you give me an alternative.<pre>
int p=checkedListBox1.SelectedIndex;
if(p==1)
{
try
{
reader = new XmlTextReader("path.xml");
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Text: //Display the text in each element.
// Console.WriteLine(reader.Value);
String s1;
s1 = reader.Value;
String ss;
ss = checkedListBox1.CheckedItems.ToString();
String sss = ss + s1;
object o3 = (object)sss;
DirectoryInfo dire = new DirectoryInfo(sss);
//DirectoryInfo[] dirs = dire.GetDirectories();
if (dire.Exists)
{
String[] folder;
folder = Directory.GetDirectories(sss);
foreach (string foldername in folder)
{
DirectoryInfo di = new DirectoryInfo(foldername);
if (di.Exists)
{
String[] files;
files = Directory.GetFiles(foldername, "*.exe*");
//FileInfo[] fi = dire.GetFiles();
foreach (String filename in files)
{
lvi = new ListViewItem();
lvi.Text = filename;
listView1.Items.Add(lvi);
}
this.Controls.Add(listView1);
}
}
}
break;
}
}
}
catch (System.Exception err)
{
MessageBox.Show("Error: " + err.Message);
}
}

Two things.
First you forgot to include the closing </pre> tag.
Secondly, what you are trying to do is sort-of like Windows Explorer so a quick google on 'explorer c#' reveals My Explorer In C#[^], as the first hit.
If that doesn't give you any ideas, google for yourself and have a look at some of the other hits.

Hi all,
I'm reading files from a certain folder and save everything into the database. I have a problem of reading multiple lines for a certain heading in a file and save them into one variable (to be saved into the database later).
e.g File content looks like this:
1. Date of Transaction :
20030728
2. Type of funds :
_Cash
3. Amount of Transaction(s) in Rand Value:
13500.00
4. Currency :
ZAR
PART H: List of available documents
Deal slip
Moneygram form
Copy of ID
BOP form
Gift declaration
I'm reading each line and save the value into a variable to be saved in the databse. e.g:
while ((line = reader.ReadLine()) != null)
{
if (line != null && line.Contains("1. Date of transaction :"))
{
line = reader.ReadLine();
DateOfTransaction = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("2. Type of funds :"))
{
line = reader.ReadLine();
TypeOfFunds = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("3. Amount of Transaction(s) in Rand Value:"))
{
line = reader.ReadLine();
AmountOfTransaction = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("4. Currency :"))
{
line = reader.ReadLine();
Currency = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("PART H: List of available documents :"))
{
line = reader.ReadLine();
PartHListOfAvailableDocs = line;
line = reader.ReadLine();
}
}
Heading (PART H: List of available documents) from the file is having multiple lines underneath it. How do I read each line and save them all in variable 'PartHListOfAvailableDocs'.
I'd really appreciate your help in this regard.
Thanks.

Hi,
you could create a loop which reads a line, appends it to what you already have (with a separator), and test for done, which either is something you would recognize as end of list, or end of file/stream.
Yours is a strange file format!

This shows that you know nothing about object oriented programming. I suggest you buy a book and read it.
And use delegates for your specific problem

hi Experts
Pls Tell Me When We Have To Use Abstract Class Or When Interface with Real Life Example
and Program in C#.NET.
I Know The difference But i Not Getting When We Have one of Them.

If you want your base type to provide some default functionality out of the box, go for an abstract class. If you want everything to be up to your derived types, go for an interface.
For instance, if I want a Parser type whose descendants will parse files from multiple clients but those file formats have nothing in common, I'd make Parser an interface.
Also bear in mind you can inherit a type from at most one class, abstract or not. Interfaces don't have such restrictions.

sorry for my bad English
- use abstract when you want to design code that only in serial derivation objects
- use interface when you want to design code that can be implemented in parallel derivation objects
sample for using abstract object
public abstract class A(){...}
public abstract class B(){...}
class DA : A{...}
class DB : B{...}
you can compare to this sample of using interface
public interface IA{...}
public interface IB{...}
class A : IA{...}
class B : IB{...}
class AB : IA, IB {...}
there are plenty resources from net, try search in Google with keywords "OOP in C#"
hope it helps

An interface says what properties, methods etc a class must have if it's to implement it but leaves the implementation up to the end class.
An abstract class will provide a default implementation.
You can implement many interfaces in one class, but only one abstract class.
Imagine you wanted to create vehicle classes Car and Bike. One thing they have in common is they have wheels so could have a property WheelCount. Because the number of wheels differs between the two classes it makes no sense to define this in a base class as it'd be wrong for one of them. Better to have an interface that both implement.
public interface IVehicle
{
int WheelCount { get; }
}Let's assume all cars have 4 wheels and all Bikes 2. We could now create base classes where this is hard coded.
public abstract class CarBase
{
public int WheelCount
{
get { return 4; }
}
}
public abstract class BikeBase
{
public int WheelCount
{
get { return 2; }
}
}Cars have doors in varying numbers so lets create an interface for that.
public interface ICar : IVehicle
{
int DoorCount { get; }
}We can now create a Car class like that derives from CarBase and implements ICar and is also IVehicle.
public class Car : CarBase, ICar
{
private int _DoorCount;
public Car(int doorCount)
{
_DoorCount = doorCount;
}
public int DoorCount
{
get { return _DoorCount; }
}
}and for the bike (no further implementation so far)
public class Bike : BikeBase, IVehicle
{ }You can now instanciate these classes treating all Cars as ICar, all Bikes as IBikes, or all vehicles as IVehicle
Car myCar = new Car(4);
Bike myBike = new Bike();
