DAtaTAble and DataRow

I have a monthcalendar control and a combo box control.
The current flow of my program is after deselecting a date, it will add a new row in a temporary DataTable.
These are the line of codes i am using:

Trow= Ttable.NewRow(); Trow[0] = this.monthCalendar1.text; Trow[1] = this.ddlType.SelectedIndex; Ttable.Rows.AddTrow

but what if the selected date already exist?
what should be done so that it will not add a new row instead update that row?

thanks a lot in advance!

Hello

Maybe you should try using the SELECT command to see if it will give you an existing row or not.
If the row exists => update it
else => Add a new one

Hi,

I have doubt by using Shadowcopying. Please anyone give samples and explanation how shadow copy is working in .net windows forms using c#.

Thanks,
kokila.

If I understand your question correctly:

Any copying creates a copy of an object so that you can re-use it. The difference between shallow and deep cloning is that generally in Shallow copying only the value properties of the object you're copying are copied, e.g:

You have an Employee object which contains the properties Name and Manager where Manager is of type Employee. Then when you do a shallow clone a new Employee object is created with the same Name but Manager still points to the original Manager object. If you Deep clone it then a copy of the Manager object referenced by Employee is also made.

So basically:

Manager 1:
    Name = "Bill"
    Manager = <code>null</code>
Employee 1:
    Name = "Bob"
    Manager = Manager 1

If you shallow clone you get:

Employee 2:
    Name = "Bob"
    Manager = Manager 1

If you deep clone you get:

Employee 2:
    Name = "Bob"
    Manager = Manager 2
Manager 2:
    Name = "Bill"
    Manager = <code>null</code>

Note that if you deep clone the copying of objects is recursive (I think) so if Manager 2's Manager was not null then a copy of Manager 2's Manager would be made as well.

Compose message with Outlook

I'm trying to do something that seemed to be very simple, but for some reason I can't find any code or documentation to help me.

What I am trying to do is compose a message, send it to Outlook and then get the user to see that message and be able to edit it (just like if they typed the message, but in this case, the system 'typed' it for them).

Just to be clear: I don't want Outlook to send the message yet, I want the user to be able to edit it prior to sending.

Outlook has plenty of command-line options. One of them may do what you want, I ran across something sometime ago where you can specify the email address, subject etc on the command-line. Just google for "Outlook command line".

An alternative, could you create the body of the email using the framework classes, save the email to somewhere on disk (e.g. temporary folder) and then open outlook with this file.

Hi,
I have a System.IO.Stream, now I want to get all data from that stream into a Byte array!
I try with the ReadToEnd() but it return the String type (=>problem with image data). I try to read the length of the stream, but it return -1. If I read byte to byte, it's OK but my program will be slow!

How can I do?

Thanks,
Hung.

Why you put burden of retrieving queries to windows service, rather you can put report data from windows service in db, and let web service directly fetch reports from db to service to asp.net page without interrupting windows service.
