Make it a while loop and use a comparison operator rather than assignment.

oops (again, bugger)  left out one of these = and yes a while would be appropriate if more than one at end of string.

There are plenty of ways of doing this. Here is one:
You can make use of LastIndexOf and Replace method along with the Length property. Check the last index of the space and if it is equal to the length of the string, replace it with nothing. You can also use the Remove method instead of Replace.

Doesn't achieve what he asked for: it only removes the last space, not all trailing spaces.

Do that recursively.

Hello guys,
I would like to have a wrapper for Rcom server in C#. I do not know what a wrapper is or how to create it.
This is what i did and i do not know if i am right or wrong.
I opened a project in C# which is integrated to R, using two dll files and this is what i did:
Open Project -> References -> Add References -> COM -> RCOM 1.0 type library (located at library/rcom/libs/rcom_srv.tlb)
This creates a dll file in my system named Interop.RCOMServerLib.dll. Is this what is meant by the wrapper file. I have no clue, its just a wild guess.
I need some help here.
Thanks,
SJ.

I have been suffering with dial-up internet access for many years, but lately it has been getting worse. I would like to write an application using C# or C++ to monitor what programs are using, and maybe hogging the connection. If anyone could point me in the best direction to get started, I would much appreciate any guidance you could give me.

Why do you want to write your own? It would be a very complex project...

Thanks I will check it out. But I was look for a winter time project to pass the time....(maybe way over my head anyway)..
Thanks again..

namespace Passing_Data
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Form2 frm = new Form2(textBox1.Text);
frm.Show();
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}
FORM 2:
namespace Passing_Data
{
public partial class Form2 : Form
{
public Form2(String strTextBox)
{
InitializeComponent();
label1.Text = strTextBox;
}
private void Form2_Load(object sender, EventArgs e)
{
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
}
}
}
this code allows me to enter data in textbox on first form and hit button and see it displayed on second form in label.
is there a way to enter data in textbos on first form and hit button and see data entered into combobox on second form?
thank you

Yes, using events. See this post[^] that I made a few days ago, as well as a working sample there is also a link to an article I wrote that explains events in much more detail if you want to gain a proper undestanding of the implementation but aimed at a beginner to events.

Example 1.
public class Employees
{
public static List<Employee> ListEmployees;
public static void FillEmployees()
{
ListEmployees = FillFromSQL();
}
}
class Program
{
static void Main(string[] args)
{
Employees.FillEmployees();
}
}
Then whenever I need to access the list of employee objects I can just call Employees.ListEmployees.Find(e => e.Name == "Mike"); I can call this anywhere in my scope because is static.
Or Example 2
public class Employees
{
private List<Employee> ListEmployees;
public void FillEmployees()
{
ListEmployees = FillFromSQL();
}
public void FindEmployee(Predicate<Employee> e)
{
return ListEmployees.Find(e);
}
}
class Program
{
Employees employees;
static void Main(string[] args)
{
employees = new Employees();
employees.FillEmployees();
}
}
Any help would be much appreciated.
Or if you have a better way of doing it that would be a great help.

I don't know the entire context of your program of course, but I think I'd use a Dictionary<string, Employee> (where the string is the name)
|
|
|

Employees can have the same name though. I do see what you saying, but problem lies more on the way I build my classes. Having most of the list static so I can access them from anywhere. I don't think this is right though. Well it is right but proberly doesn't follow best practises.

A "best practice" often turns into a golden hammer. There's a lot of ways to load data, some make sense in a webapp, others make more sense in a console-application. Using NHibernate from a console-app just to update the name of a single employee would be overkill.
Most answers here will be variations on the ActiveRecord-pattern to store a single record. It would also make sense to store multiple records in some kind of collection[^].

I would do this:
public class Employee
{
}
public class EmployeeList : List<Employee>
{
public EmployeeList(bool populateNow)
{
if (populateNow)
{
GetFromDatabase();
}
}
public void GetFromDatabase()
{
this.AddRange(blah blah);
}
}
EmployeeList employees = new EmployeeList(true);
The list should know how to load itself, and can take care of all the nasty stuff behind the scenes and abstracted out of the UI code.

Thanks, nice way of doing it.
If you wanted to initialize the list once at start of your application and then be able to call it through out the scope of you app, how would you do it?
|
|
|
|

Put it in a static class and intitialize it in the constructor of the that class.
public static class Globals
{
public static EmployeeList Employees { get; private set; }
static Globals()
{
Employees = new EmployeeList(true);
}
}

If you want to cache your Employees for use throughout your application and it's acceptable to not reload them (i.e. they will not be changed by someone else acessing the DB) then it's OK to keep a static reference.
One or two points though. Don't make fields public, you should create a static readonly property (i.e. only a getter) to expose the cached List.
If you have a lot of data stored in your list then you may end up with memory issues, so it may be wise to only store the basic information such as ID and Name, and look up the rest of the data when required.
Have you considered using the Singleton pattern and have a Manager/Factory class that creates the list only when it is first needed? It won't offer any huge improvements, but can be a more logical approach. Without knowing the exact requirements and other implementation details it's hard to say but may be worth investigating.

Thanks,
I do have quite a few records, anywhere up to 10000. I do quite a few checks on the List though, every day I get a bulk file of employees and check if the employee exists, if he does I need to check if any of his details have changed. (Every single field)
I think one select of all the data and then data lookups would be faster then 10000 selects?
|
|
|
|

10000 doesn't sound like a lot, it depends on how much space each element takes. If it's only say 100 bytes then that's approx 1MB of memory. If however you have names, addresses, photo etc... each record could be much larger. If it were a meg each then that would be 10GB and unless you have a mega system you would come crashing to a halt.
Even if useage is low, the volume of Employees may change, and the storage requirements may expand later (scans of signed contracts of employemt as an example) so I would build for that now and just cache the data that is required to make the application useable, and do a DB lookup for the non cached data when needed.
