If you don't show that you at least tried to solve this on your own (include the query you come up with until now and which does not work), most probably nobody here will help you cause this forum is no place to let others completely do your work.

what are the fields on the history record that you want to display?

Wow - you got a lot of responses and very little help. That doesn't surprise me, you posted an message with a meaningless header ( EVERYONE thinks their question is 'urgent', what would the forum look like if they all said so ? ), you provide no info with which people can help you, and apparently you've cross posted this, instead of taking the time to post in the right place, with a question that shows you've tried to do some work yourself, and gives people the info they need to help you.
I suggest instead of feeling discouraged, you think it through and try again.

It is important to give to your subject a meaning. It should sumarize your text.
DAO provided nice function like .movefirst and .movelast. Nowadays i see no other alternative than making the query into a DataReader and read it from top to bottom.
In addition, if your table has a sequencer to differenciate the key (main key built from a foreign key + sequencer), then you should use two queries with min and max to retrieve your records.

Dear friends
I have one datagrid which has data from one of the table as employee_master.
on click of any record on the grid I want to get the value of first cell that is employee code. but when I clicked first time it does not give me any value. on second time click it gives me the value. How can I get the value of the cells which I need in first click only.
Your quick response will be highly appreciated.
Thanks

Should you work with a dataGridView, try to treat other events like CellClick or CellMouseClick

As an expansion to this, use a DataGridView and a BindingSource. It provides superior data management capabilities. Search the CP articles for a good one on data binding and the datagridview

Try open your package and set the data type of your working field(s) to be DT_WSTR

If you want to do something to the selected node, you *need* to use the selected node property.

For example:
<br />
YourNode.BackColor = Color.Green;<br />
YourNode.ForeColor = Color.White;

Hello all!
I would like to write a method like this:
public static T Sum<T>(T[] data)
{
T s = default(T);
if(data.Length == 0)
throw new ArgumentException("No data!");
for(int i = 0; 0 < data.Length; i++)
{
s = s + data[i];
}
return s;
}
Unfortunately this code doesn't work.
Compiler Error: The operator "+" can not be applied to operands of type "T" and "T".
What's wrong? Are there any constraints to apply?
Thank's in advance!

The compiler can't guarantee that 2 objects of type T have a + operator defined.
What if T was a MySQLConnection for instance?
I just did a google for generics c# operator and look what came up:
http://www.codeproject.com/csharp/genericnumerics.asp
haven't read the article but probably worth a read.

You can use the where T : format to specify what T needs to be. I don't know if you can specify that T impliments operator +, tho. Generics are very dumb, compared to C++ templates.

I'm trying to load an image into a byte array. The following code seems to be OK for the moment but i'm worried that it's not right.
FileStream fs = new FileStream(FileName,FileMode.Open);<br />
byte [] ImageData = new byte[fs.Length];<br />
fs.Read(ImageData,0,(int)fs.Length);
Firstly, while i can't see anyone loading files bigger than int.MaxValue any time soon, it's always nice to future proof your code and someone might load a video that big, even today. For the application I'm using it for I'll probably block files over about 10 Meg anyway so I can ignore this issue.(I might stick in a LATER: comment and come back to it)
Second and of more immediate concern is that I read somewhere (but have now lost the link) that fs.Read will block until it has some data, not necessarily all the data in the stream.
Is my simple code OK or should I be checking whether the stream is fully loaded before i do things with the data? It seems to work allright at the moment but this is a reasonably fast machine with good disks and not much swap file use.

Looks fine to me. You want the image file, in it's encoded format, right ?

I'm putting the file into a DB so as long as it's a valid byte array I hope it'll be OK when i get it back out again.
Was just a bit worried that the webpage i read yesterday used about 20 klines of code to achieve the same result.
Thanks for your swift reply
