Breaking it down will just help you work out where the problem is. It won't change that you are making a call which is returning null, and not checking it.

i broke it down some more and narrowed to problem down to the string "value" i made value an object datatype and it now works.

this is the problem

Create a User class. This class should at least contain the following fields:
User ID
Password
First Name
Last Name
E-mail Address
Status - valid values are 'Inactive', 'Active', 'Deleted'
Define constructors that accept the following parameter lists:
All parameters: User ID, Password, First Name, Last Name, E-mail Address, Status
User ID, Password and E-mail Address
User ID and Password Only
** The status field should be initialized to 'Active' upon creation
** Constructors 2 and 3 should use a constructor initializer

Define read-only properties that return the following:
IsActive – whether or not the account's status is active
FullName – a concatenation of the account's first and last names
Define additional properties that behave as follows:
UserID
Set operation should ensure the user id does not start with a digit and should only update the user id field if the given value is valid
Get operation just returns the user id
Password

pls help me... Cry | :((

just notify me through my email...

So because it's got to be handed in soon and you didn't do it in time you want someone else to do it for you?

every homework request comes with a sob story. This is really straight forward. If you try to do it yourself and you need help with specific things, that's different, but for you to just post your homework and hope someone will do it is, frankly, kind of rude.

So, I ask again, which specific bits are confusing you ? Do you want to ask some specific questions to help you in approaching this task ?

Which part of your (pretty simple) homework is confusing you ? This is a basic exercise in OO. We never do homework, but this in particular, is pretty vital for you to understand, and really not hard.

I would guarentee that any text you've been assigned will cover all you need to know to do this.

You need to check 'Ignore HTML tags in this message (good for code snippets)' for your XML to be properly rendered. The schema is irrelevant, however. You can use anything you like to play the mp3, be it DirectSound, the Windows Media Player control, etc. I don't believe any of those things offer the ability to play part of a track, but they all let you set the position in the track, so it's a case of setting a timer so you can stop it when the section ends.

Thanx! so I need set a posintion (firstPos) in the file, play it for (firstPos - secodPos) seconds?
but how can I explain for control to play only (firstPos - secodPos) seconds? is any property for this in the control?

As I said, no. You can set the position, but not the end position. So, you need to set a timer that goes off as you hit the end position, so you can move the position or stop it.

Process problems

Hi,

I have some problems while using a Process to start an Microsoft Active Sync installation.
I am developing an Installer program(In .Net 1.1) to install some different programs in an certain order.

But when installing Microsoft Active Sync from the Installer program the user is promted to restart the computer after succesfull install(Default by Microsoft). If the user press "Yes",
I need to be sure that the Installer Program & the Process are closed because else there will occur an error.

I have tried to use Process.WaitForExit and then this.Close(), but that did not work

I Also need to do a "check" in the registry database, to see if the user has canceled the Install(Then he needs to be promted if he want's to install again), or the install was succesfull but the user did not want's to restart the computer

Regards
Mikkel Hansen
