How would I, for every 10 numbers in an int, do an event? What I need help with is the foreach part? I'm confused as of what exactly to put: foreach (myInt in ???)
{
}
Thanks.

Every 10 digits in what int ? You mean as in the int 12345678901 fires one event ? When ? When it's being entered ? If you have a string you can use the length property to check how long it is.

Convert the number to a string, then loop through the characters in that string.

int.MaxValue is 2147483647. (Which is 10 digits).
Without using a 'bigger' space to store an integer (Int64) this will only 'fire' once if at all.
If this is true and you are using an int then if (myInt > 999999999)... will be sufficient.
If the integer is in string form then myStr.Length / 10 will give you the number of 'ten digits' there are in the string.

MasterSharp,
I think you've misunderstood the foreach slightly.
Foreach (int currentInt in myInt)
currentInt is the current int the foreach is at in the iteration.
myInt is the collection you want to iterate through.
So, if you wanted to fire an event every 10 digits, you could do:
int myInt = 100;<br />
int tenDigit = 0;<br />
foreach (int currentInt in myInt)<br />
{<br />
if (tenDigit == 10)<br />
{<br />
tenDigit = 0;<br />
<br />
If (Event != null)<br />
Event(this, new EventArgs());<br />
}<br />
<br />
tenDigit++;<br />
}
Hope this helps.
Regards,
Gareth.

foreach (int currentInt in myInt)
myInt is an integer. Foreach requires a collection, or some object that has an enumerator defined.

Malcolm Smart,
Ye. My mistake, was thinking of just a normal for();

In regards to Gareth's post, you can't use foreach on non-array objects.

Hey all,
I would like, if possible, you could tell me some ideas for projects.

Thanks so much, any help is greatly appreciate it!!

Your friend is best asking his instructor for guidance. That is what they are supposed to be there for.

I agree on that. I asked my friend to find out what kind of project or field his professor wanted but all my friend got from him was a "Think what you would like to do and we talk on Tuesday."
This is very important because this is like one big step to graduate from University.
Another thing is that my friend doesn't really know a thing about programming or hardware, so basically i will be tutoring/helping him build the project from the beginning to the end. I know there are a lot of "ethic/moral" principles involve and it might be wrong to do it. But as long as i don't cross the line between helping him to do it and do it myself i think it will be ok.
I thought of a: "Vehicle with a camera and fingerprint reader to ID the driver and the passengers" good for companies with no passengers policies. This is project is more suited for my country Dominican Republic where people tends to give a ride to anyone.
Also i thought of Mobile/smartphone application that constantly send a message where the owner is located, but the fact of violating the principle of privacy makes me uncomfortable; so i am about to discard that idea.
I have this tools, maybe it will help to know i have them:
* Microsoft Visual Studio 2005
* Microsoft Sql Server 2005
* Microsoft Finger Print Reader & the GrFinger SDK
* An extra low resolution small camera
* If it is needed i can get a GPS receiver.
* 2 PDA with WM 5
* Belkin Bluetooth adapter
* a few Atmega 8 with the "programmer"
Again Thanks for the help,
Best regards.

kingletas,
If your friend is not a programmer, do you think he will be able to do your idea of a camera and finger print reader?, with that idea, you will be writing it your self. I think you should go for something FAR simpler: a CRM app (SalesForce.com) or a content management website like Blackboard.com.
Think SIMPLE.

Gareth.

For someone who really isn't a programmer, this would be very bad. Try something simple.

There should be an Add method for adding new rows to the datagrid.

//Create a new instance of DataSet
DataSet objDataSet = new DataSet("TableName");
//Create a new DataRow in the DataSet
DataRow objDataRow = objDataSet.Tables["TableName"].NewRow();
//Assigning text values to their respective data columns
objDataRow["items"] = txtItems.Text;
objDataRow["cost"] = txtCost.Text;
objDataRow["date"] = txtDate.Text;
//Adding the row in the DataSet
objDataSet.Tables["TableName"].Rows.Add(objDataRow);

Good job doing his work for him. You didn't add any real learning value for him by doing it for him.

this builds fine but there is null exception coming up when i try to input data on the line where the new row is created, am i right in thinking this needs a value? if so what value can i give it?
