Which version of Visual Studio?? In 2005 (.NET Framework 2.0) you just have to change the BackColor property of the ToolStrip object to the color you want.

Hi all,
Can anybody send me the code to list out all the oracle servers in the network and all the oracle databases in a particular server. I mean, i need to do it through ODBC. The code for doing the same for SQL is as follows,if possible pls point out what all changes I need to add to get the oracle list, i have tried out the "DRIVER= Oracle ODBC Driver" change.That is not working.
'code starts here
'Note : Include "DRIVER= Oracle ODBC Driver" for the SQL_DRIVER_STR variable in the code below and try it.

VB6 I guess ? Please don't ask the same thing twice.
AFAIK, you need to extend the MSFlexGrid to support editing.

Sir.Madam,
I wanted to add a new property into the combo box.But before that ,I tried to write Inherits System.Windows.Forms.ComboBox.But that is creating a problem.
Base class System.Windows.Forms.ComboBox specified for component1 cannot be different from base class System.ComponentModel.Component of one of its other partial types.
I am creating a component class to do this.
Please help.
Thanks and Regards
Pankaj

Pankaj,
If you're using Visual Studio 2005, you'll notice that when you create for example, a component class, 2 files will be generated. One of the files, the one named YourComponent.Designer.vb is the one used by the designer. If you look into this file you'll find your problem. This file is the one containing the inherit sentence, and by default it comes with System.ComponentModel.Component.
If you just change this with System.Windows.Forms.ComboBox, your component will work perfectly.
Hope it works!

You want to specify two numbers and get back a sequence, using XSL ? Why ? We have an XML/XSL forum, BTW.

I have two for loops from which I am displaying the folder items in a table.
i.e. from outer for loop I am displaying the folder names and from inner loop
I am displaying the contents of that folders .
Now I want to do paging since in case of hundreds and thousands of msgs in my inbox.
So I think datagrid is the best option for tht
but I am getting how to populate the datagrid according to this and do paging in tht.

your datagrid can be told to handle paging for you. If you build an array or list of the items you want to display, you can use that as a datasource.

The VB.NET code for displaying folder in an HTML table is:
'Looping all the subfolders
For j = 1 To 2
sfolder = oFol.Item(j)
s.WriteLine(sfolder.Name)
'Looping the Mailitems of the Subfolders with the sender's name, Subject,Recevied Time,Size of the mail
Dim i As Integer
For i = oItems.Count To 1 Step -1
s.WriteLine(oMail.Subject)
Next
Next
How can I make an array or list of the items and display it to datagrid and allow paging.

Create a list first, then instead of calling writeline, add the items to your list. Of course, this will give you a list, not a tree.

That's the problem that i am not getting how to make an array or list from these for loops and populate the items into the datagrid to do further formatting like paging and all!
I want the exact look like a mailbox i.e. when we click on the folder name then the respective folder contents should be displayed in the datagrid with paging.
