It is used to call a method in another class, such as an event, or to notify one class of something that happens in another.

If you want more detail, try googling for some articles on it. They will provide more and better detail than I will on the fly

Dear All,
I am using VB.NET 2003 and MS Access 2003 and my project is always used the database.
Pls check this code,
Public Sub DR()
..........
............
Dim drd1 As System.Data.OleDb.OleDbDataReader
SelectedDataReader(drd1)
Do While drd1.Read
Dim a As Integer
price(a) = drd1.GetDouble(0)
a = a + 1
Loop
drd1.Close()
...............
..........
............
End Sub
Data reader is in another module.
Module CUFA
............
...............
Public Sub SelectedDataReader(ByRef drd1)
Dim cmd1 As New System.Data.OleDb.OleDbCommand
cmd1.Connection = cnn1
cmd1.CommandText = "SELECT Price FROM Selected"
Try
drd1 = cmd1.ExecuteReader
Catch ex As SystemException
End Try
cmd1.Dispose()
End Sub
...........
...........
End Module
Pls let me know is this correct?
And data connection is opened another module. It opens starting of my project and closes end of my project. During that time more than 200 data readers and commands open and close.

To do what??
As far as your code goes, it's a lousy design. That's about all I can say about this....

Why?? Why not just have a method in your DAL that creates a DataReader for your command and returns it?? Why are you creating a DataReader in one place, creating a command for it in another, using a "global" variable for a connection, chosing bad names for your methods, using two different classes/modules to build this reader, ..., need I continue??
You're really missing the point of encapsulation. This code can be done in a single class, using at a minimum, 2 methods, and a max of 4. One method to retrieve the connection string from a config file, a second to create a connection object (it's also acceptable to combine these first two into one method), and a third to create the data reader. You may either return the data reader, or create another method to use the datareader to create your array, though there are other methods of doing what your code looks like it's doing.

Hi,
I am using VB.NET 1.1 on a Windows application. It is an import program. There is a start and stop time, during these 2 times the back is run so the import program should pause. How do I check if every second if the current time is out of the time range so that I can resume the import program after the stop time.
So if I type in 19:00 for the start time and 02:00 time then the program pauses, so I will need to know when it is 1 second past 02:00 so that the import can continue.
Regards

Just use DateTime.Now in a timer. It doesn't have to be 1 second past, just check if it's past.

There are articles about on how to do this, but it's not built in, you have to write or find code to do it.

Thanks jathoo for ur reply.
I am adding the image at run time.The code I am using to add link the image to the picture box is
Me.PicStrikeRate.Image = Me.ImageList2.Images(0)
At run time it is not working but If I added the same picture at design time it works.
Any idea how to fix this?

first of all why you going for code?(you can simply do it on GUI mode, i told u on up)
Me.PicStrikeRate.Image = Me.ImageList2.Images(0)
on this code you are puting ur image to imagelist but , as i know .gif file will only work on picturebox( i don know it may work on imagelist or not and i thing i wont work, didnt try it yet)
so. if u want u have to directly adding the image to picturebox using code

It's not supported by the standard control. You'd have to create your own version of the control, adding the custom properties and painting code to draw each item in the different color you want.

sir,
i never create control & no experience for adding custom properties.
can you guide me or provide some link in proper direction for create this type of control or Properties.
