Ok, I'm making this program for my statistic class Dealing with boundaries and Limits..
When user enters a set of numbers, I would like it to count the same numbers it enters, for example.
1,2,7,8,3,5,8,8.
1 = 1
2 = 1
3 = 1
5 = 1
8 = 3
without writing like 100 if else loops
if ( num =1)
num1 += 1;
else
if ( num =2)
num2 += 1;
etc, any idea how to do this program?

Can you use a dictionary with logic like this -
Dictionary<int, int> objCount;<br />
int num;
if (objCount.ContainsKey(num))<br />
{<br />
objCount[num]++;<br />
}<br />
else<br />
{<br />
objCount.Add(num, 1);<br />
}

int[] myNumberCounter = new int[100]; <br />
<br />
myNumberCounter[12]++;<br />
myNumberCounter[2]++;<br />
myNumberCounter[19]++;<br />

Whether that is a good idea or not depends on what kind of data you are going to get. If the data is an int (i.e. a 32 bit number), then declaring an array to hold it is a little excessive. Likewise, if the data is likely to be "clumpy" with many values below 1000, and many above 30000, but few in between, then an array is unlikely to be efficient.
Additionally, you will need to provide checking to ensure you will not exceed the arry blounds. Extending an array is very inefficient, as the entire array has to be copied to a new, bigger, array.
If you do not know what data you will recieve, then a Dictionary is likely to be a better solution.
All those who believe in psycho kinesis, raise my hand.

I agree - mostly - in this case it was "sort of" indicated values in the area of
0- ~100. And if that's the case i would deam Dictionary excessive, otherwise I agree.

Use LINQ?
var list = new int[] { 1, 2, 7, 8, 3, 5, 8, 8 };
var query = from i in list
group i by i into grp
select new
{
Number = grp.Key,
Count = grp.Count()
};
var counts = query.ToDictionary(t => t.Number, t => t.Count);

hi
i have a application which need a port to send data, but im in need of a utility which will tell me the availalbe ports, and whether they are opened or can they be used??

I think you already asked this question, didn't you? Or do you want some different information this time?

Just write the code to try opening the port. If you get an exception, it's not available.

Hi,
My project has layered architecture. Business logic has separate project and in this project I have to use some registered OCX method.
Current situation:
In presentation layer I have window forms. It is easy to add OCX control in toolbox and draw it on any form. Object of drawn OCX control can be used for calling its methods. But I don't want to do it in presentation layer.
I have following question:
Should I manually add reference of OCX in business logic project? If yes then how I can use it in cs files?
Please tell me how to call method of OCX without having forms. That means no creation of control at design time.
Thanks.

You probably need to create an interface which exposes few methods that acts like facade methods. This methods should eventually call the methods on the control. With this, your business logic project will not be aware of the OCX controls. You can inject this interface instance into your business classes from the presentation layer.
Best wishes,
Navaneeth

hi
Is there any way i could check whether the data has been sent in serial port??

You really ought to learn to use search engines. I found a lot of references. Here's one, but I'll let you learn how to find more info.

I am using the code at the botoom to generate the monthly contracts invoices and save every invoice as a separate PDF I am generating all invoices to have the same GUID so it will be easier to retrieve all but it will be more than one invoice so for example they will all have same GUID but I will have 5 or 6 companies. I want to use the same code below to generate the separate PDFs using the invoice_number as file name.
private void generate_invoices()
{
this.Cursor = Cursors.WaitCursor;
sql_connection = new SqlConnection(public_var.sql_server_connection);
try
{
sql_connection.Open();
sql_command = new SqlCommand("sp_get_account_book_by_book_guid", sql_connection);
sql_command.CommandType = CommandType.StoredProcedure;
sql_command.Parameters.Add("@book_guid", SqlDbType.UniqueIdentifier).Value = book_guid;
DataSet data_set = new dsReports();
reportTICS.Reset();
sql_reader = sql_command.ExecuteReader();
data_set.Tables[0].Load(sql_reader);
reportTICS.LocalReport.ReportEmbeddedResource = "dsReports_sp_get_account_book_by_book_guid";
reportTICS.LocalReport.ReportPath = @"C:\Users\Jassim\Documents\Visual Studio 2008\Projects\Takhlees\Takhlees\envoice.rdlc";
ReportDataSource rds = new ReportDataSource();
rds.Name = "dsReports_sp_get_account_book_by_book_guid";

reportTICS.LocalReport.DataSources.Add(rds);
ReportDataSource rds2 = new ReportDataSource();
rds2.Name = "dsReports_sp_get_account_book_by_account_number";
rds2.Value = data_set.Tables[0];
reportTICS.LocalReport.DataSources.Add(rds2);
reportTICS.LocalReport.Refresh();
reportTICS.RefreshReport();

}
Process.Start(file_path);
}

Hi all
How can i add a column to mydatagridview in code that the duty of this row is deleting the current row?
|
|
|
|

Basically you need to create a column and add it to the columns collection. As far as it's duty, I have no idea what you are talking about!

Thanks for your help;
I mean that I want a column for deleting the current row that has been clicked;
Additionally i want a gridview that has a deleting ability and i want to add this ability to my datagrtidview in code.
|
|
|
|
|
Well, in my applications, selecting the row header and pressing the delete key deletes the row. If you need something different, then maybe using a checkbox or button column and doing the delete when that is selected would work, but it seems convoluted to me.
Or maybe I still don't understand what you want to do?
