Hi,
In this code for example:
double Start =1;
double Jump =0.2;
double End = 2;
List<double> m_List = new List<double>();
for(double Num = Start ; num<=End;Num+=Jump)
m_List.Add(num);
i want to get the numbers 1 , 1.2 , 1.4 , 1.6 , 1.8 , 2
But im getting 1 , 1.2 ,1.4 ,1.5999999 ,1.79999999 ,1.99999999
How can i fix it?
(The numbers can be in 2e-04,300,6e-8 for example)

have a look at decimal[^] that might be better for you

you can use math() function to convert e.g 1.5999999 to 1.6 using math.ceil or math.floor

Hi,
How to pass parameters to a Access database using oledb provider and enterprise library. We used below code to update category table which has two colums ID and CategoryName. The code runs successfully without any errors but the table row remains unchanged. What could be the problem
Database db = DatabaseFactory.CreateDatabase("MyDemoConnection");
DbCommand dbCommand = db.GetSqlStringCommand("Update Category SET CategoryName = @CategoryName WHERE ID = @ID");
db.AddInParameter(dbCommand, "@ID", DbType.Int32,(int) 1);
db.AddInParameter(dbCommand, "@CategoryName", DbType.String, "Just a Change");
int i = db.ExecuteNonQuery(dbCommand);
<connectionStrings>
<add name="MyDemoConnection"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\db1.mdb;User Id=admin;Password=;"
providerName="System.Data.OleDb"/>
</connectionStrings>
It would be great if any one can redirect me to the exact way

Generally speaking, it is best to first save the excel file as a delimited text file, or xml file, in Excel itself.
If that is not an option, you could try to convert it in your application first, and only then try to import it into your database.
You can try to import directly from the Excel file, but the code will be sensitive to version changes of Excel (it will work for Excel 2003 but not for Excel 2007 for example)
Another option is ODBC.
My advice is free, and you may get what you paid for.

Well, if a network connection exists, you can use it. You can't just hijack another app to find it tho

Well, if its course work talk to your tutor, if its a task at work talk to your manager, and if its a job you bid for and won tell your client you are told lies and you have no idea what you are doing.
Nobody is going to provide code for you.

It's funny, your profile says your are from the USA.
Why I don't have a clue of what you are trying to achieve after reading your question?
Surely you master the English well enough to ask a meaningful question?

Can anyone help me by giving sample source code.

If you'd like the source code to do VOIP, I recommend going over to the job site and hiring someone to write it.

I have a repeater that I am dynamically generating controls for based on some DB data using a class inheriting ITemplate. I am currently generating a checkbox and a textbox for each row in the DB which is working fine. The problem is that I want the textbox to be invisible until the user clicks the checkbox corresponding to the adjacent textbox. I have wired up the click changed event, but I cannot access the textbox only the checkbox. Should I use a Delegate or some other method of enabling and disabling the visibility of the textbox.

I ended up using javascript to hide and unhide the textbox.

As a final year project I am interested in doing p2p voip.But I have no idea how to start the project.Plz provide me some sample tutorial or research pages rather than links.
Looking for your positive response.

Well, all you need for that, is code to compress voice and deliver it over the web. Search for audio compression, not voip.

Well, you're not talking about any control built in to the framework, so you need to write your own.

Of course.
ajithnamboodiri wrote: if so can you plz help me to start with
I don't know how to help you, given that the answer is to create a user control and then visually work out how to build it.

Perhaps you need a book on Winforms development ?
