One last question. What if Int64 and long is too short? What I am doing is the following.
I have a list of 100 000 records which are all long numbers and can be upto 11 digits long some of them. Now, I need to calculate a total for them, add them all together. The ansrew I think can be upto 16 digits long but it seems like Int64 only returns 13 digits.
Anyway, I can use something else that would return a much bigger value?

I think my problem here is the foreach loop. DO I need to use foreach? Can I structure this different to not use a foreach loop and avoid it from itterating so many times?
Code again:
long sum = 0;
foreach (imphash hsm in res)
{
sum += Convert.ToInt64(hsm.Field1.ToString());
CalculateNum(sum);
}
}
void CalculateNum(long list)
{
long sum = 0;
for (long i = 0; i < list.ToString().Length; i++)
{
sum += Convert.ToInt64(list);
txtboxdsptxt.Text =(sum.ToString() + Environment.NewLine);
}
}

Kwagga, this has been answered 3 times now. Im not sure what it is you're not getting about this seemingly simple task. You have a list of numbers as strings, parse each number into an integer (as discussed you may need a bigger integer than int so use long) and sum them.
What your code does:
1) for each number in the list
2) parse it to a long
( good so far but... )
3) send the long to a method which converts it back to a string (list.ToString())
4) go character by character of the number and convert the original long back to a long (sum += Convert.ToInt64(list);)
( its getting worse... )
5) sum the number again.
For the final time (i hope) the second method is supervlous.
long sum = 0;
foreach (imphash hsm in res)
{
sum += Convert.ToInt64(hsm.Field1.ToString());
}
txtboxdsptxt.Text =(sum.ToString());

Thanks mate. However,Int64 is not bog enough for the result. Anything else that would be big enough? Int64 only returns a 13 digit number causing it not to calculate correctly.

About your first question I am not sure where this information would help you. This is handled by the protocol itself and if there is an error/exception, it would be shown.
However if you still want the information, you can use any ftp client like Filezilla etc and enable tracing capabilities (to create a trace log) which would show you the data sent and received.
For OTPS command, please refer the RFC.

I have created a service which keep track of c:\program files folder and record all the creation & deletions of in the folder. I have created a setup too to install it, And i know how how to set the service type to automatic and restart the machine, But i want to know the place where the restart code should be placed in the project. means after installation i want the computer to restart itself.

Write an installer that installs the service and then prompts the user to restart the machine. BTW, you should do everything you can to avoid requiring a reboot. Users hate that.

Depending on how many tere are, you can have properties on the form that set the values and set them before showing it, or pass them through on the constructor. It also depends if you want to force your user to provide the values.
If the second form is already visible and you want to set it, then properties or using a delegate are your options

Hello,
Is there any way to communicate between a single windows form, and multiple DLLs (being used in form's code...) without using IPC?

Do rate the reply, if it helps or even if it doesnot, because it helps the members to know, what solved the issue. Thanks.

If the dlls are imported into the main app, you can just use delegates.

DataGridView has CellValidating and CellValidated events. You can use them for cell validation.

I am new programming and this is probably a stupid question but, how do you create a new form using a button?
I know I have learned it somewhere but I just simply forgot. Is it something like new Form = formname.Form I can't remember too well. Can anyone help?

I would recommend reading a beginners book at this point. I assume you don't have one, or you'd be referring to it.
Form1 f = new Form1();
f.ShowDialog();

Hi,
please refer me to a sample project (on the web) that is based on 3 layers, and data access code and bussiness code in it be clear.
I want to see a sample data access and bussiness code.

I think the ASP.NET forum would be the right place to ask this question, but even there, we are here to answer specific questions, not to send people projects. We'd be googling for it, same as you can.

Hi may i know what is the 0000000 mean?
CREATE PROCEDURE [users_retrieve]
@UserId bigint = 00000000,

zero. zip. Nada.
It's a default value. 0 would be fine.
In future, we have a SQL forum.
