I just tried it and it return current date and the time from your input.
For example :
DateTime d = DateTime.Parse("15:00");
Console.WriteLine(d.ToString());
Then you will see : 12.07.2006 15:00

You can use DateTime.Parse("15:00"). But in VS2005, it is better to use DateTime.TryParse(...). It is because,according to my info, if DateTime.Parse can't convert string to DateTime, it will throw exception. But DateTime.TryParse(...) will return boolean that indicates whether String is converted to DateTime and DateTime as second out parameter of TryParse. If it can't, it will simple return false.

I tried below codes. It didn't show any error message but It couldn't change the value.
MessageBox.Show(ds.Tables[1].Rows[0].ItemArray[1].ToString());
ds.Tables[1].Rows[0].BeginEdit();
ds.Tables[1].Rows[0].ItemArray[1] = "akutumm";
ds.Tables[1].Rows[0].AcceptChanges();
MessageBox.Show(ds.Tables[1].Rows[0].ItemArray[1].ToString());

i have a mdi form and a child form developed in C#. On form load of a child form i am retrieving data from data base ( i am using mysql).
my problem is when i load child form for the first time it takes around 5sec, there after if i open the same form again it only takes around 1sec.
Can any body tell my where it exactly taking time to load for the first time, and suggest me where should i check.

This is happening becouse initialy application is compiled in the form of IL(intermediate language) and when it is executed it is compiled in to machine
specific code on which it is running by JIT(just in time compiler),so when the application is executed first time the IL is compiled to machine specific code
that is why it takes some time but when reuse the sme part of application then
the compiled codes are already there,so it take less time becouse JIT compiles part of application called once,that is why initialy it takes more time then
later on.

Good one. And you can use NGen to pre JIT, or so I read, never tried it myself.

Exactly? You are kidding right?
One wild guess would be that you are not creating the MySql connection until you load the child form. If so try loading it at application start-up, if that is the problem you should see the application take longer to load but the first child form should load faster.
Another wild guess is that the child form references several assemblies that are not loaded until the first child form is loaded but 5 seconds seems a bit extreme.
I am out of guesses for now.

1. How do you retrive data? If you use select directly from database tables then it is better to create views or stored procedures and select data from them using sql-command parameters. In this case server will already have compiled queries even at the firs time.
2. Look at this article[^]. It may help you.

Well, it depends on how things are set up. SMS messages don't just arrive at your USB port. They arrive at some bit of equipment you plug into your USB port, and how you talk to that will depend on the protocol/drivers (if there any).
You should consult the manual of the thing you plug in to determine how to talk to it - it may just be a standard serial stream.

Rob Philpott.

Note: everything below applies to Visual Studio 2003 using c# and windows forms.
I have an application that allows the user to enter an alarm, it's added to a list and saved to a file and the alarm is fired when it's appropriate. I've got a system tray icon which allows them to either close the program or show the form. They have an option on the form to send it to the systray so that it's essentially "hidden." That works just fine.
However, I want to give them an option to automatically send it to the system tray on startup. I got it to work where it will minimize the form, but that's not right. I want to get the Hide() or visible = false instead as that will remove the window completely. Anyone know of a way to get this to work? I've tried everything that I can think of but can't get it to work right.

HI,
Set the ShowInTaskBar property of the form False
and set the .Visible property to false.
This should do ur work.

Pramod
