just call shell("ipconfig" > "C:\ip.txt")
it will create the text file at location C:\ip.txt
it contains the ip and other things too.
read it and get information
 The real question is, would you do that in your project?? Would you create a text file each time and read from it every time you want the ip address? I'd bet that no customer would accept such a solution.

ERROR:Format() is a type and cannot be used as an expression
Why is it this function works smoothly in VB.NET 2003?
Format(1234, "0000")
but when i try to used it in Visual Basic 2005
an error occurs just like this...
'Format' is a type and cannot be used as an expression
here's my code:
****************************************
Function AutoGenerateEmpID(ByVal strSQL As String) As String
Try
Dim strID As String
Dim strCharYr As String
Dim strDigit As String
openDB() 'this is just my customized function..
dbRecordset.Open(strSQL, dbConnection)
strDigit = Format(Val(dbRecordset.Fields("IDNo").Value) + 1, "0000") 'my error occurs here...
strCharYr = Microsoft.VisualBasic.Right(Year(Now), 2)
strID = strCharYr & "-" & strDigit
'dbRecordset.Fields(0).Value
closeDB() 'this is just my customized function..
Return strID
Catch ex As Exception
MsgBox(ex.ToString())
End Try
End Function
***************************
Note: expect that dbRecordset.Fields("IDNo").Value returns an numbers which is in the form of string
***********************************
Please help....
I cant figure it out my self why is that so??
Is it there something i just forgot to imports some namespace or what??
Please help...
Thanks in advance!!

VB2005 obviously removes still more VB6 nastiness. You need string.Format

For l = 0 To 4

Did you try using the DTS Wizard option that comes with SQLServer. There is an option to transfer between heterogenous data sources in it.

Dear Everyone.....
Hope you will be in best of your health....
I have an immediate assignment from my boss to collect the knowledge that what are the best practices & architecture to deal with databaes, tables using vb .net...
Actual problem is that i want to know simply that what way i should adopt for the subject. weather i should go with using data source managers or i should create objects, classes, procedures or whatsoever is...
i can quote an example of my question as;
CONTROL --> DATABINDINGS --> DATASOURCE -->
DATA-ADAPTER-->DATABASE
please help me...
thanks

Your boss wants you to learn how to properly write a database application ?
I'm all for a seperate data layer, and all SQL in stored procs. Some people swear by ORMs.

Dear Graus,
thank you so much for the immediate response....
you have gotton my problem.... i am going for a one-hour presenation, so how i can describe in detail about the data layer...
my problem is not actually the conversion but to find out the exact model which i should follow to deal with my databases.
i mean what is the best method to deal with records that saves my memory, facilites me more, etc. etc.
please disclose more if you can....
thanks

Hi,
At a minimum you'll need to cover:
* Ad-hoc data access
* Stored procedure based DLs
* Custom business objects
* Template based ORM / Handmade ORM
* ORM mapping tools.
That list is pretty much in order from most-flexible to least-flexible, but also from most-effort to least-effort (in general). Your boss wants to hear about what the upfront cost is, how quick you can develop, how reliable your code will be, and the maintainance cost if things need to be changed.
Remember your boss is less interested in the technical details, and more interested in the risks and benefits of your choices!
I have to admit a certain bias towards ORM, as my company sells ORM tools. For a presentation you can certainly find a lot of "boss friendly" material on how ORM tools will benefit your development process on the site linked in my signature. Although we are writing about our products - the general gist applies to a lot of ORM tools.

Dear friend,
thanks once again for the nice response...
you are absolutely right in your sense.
I am just telling you the whole story of my last meeting with my boss. He is very conceptual and technical person. he is highly able to criticize the matters.
he is straight forwardly asking me the following questions
1. What is .net framework's internal architecture?
2. What are database oriented best practices in .net?
3. how would be application design in .net?
4. overview of .net studio?
5. .net framework multilanguge support?
6. Database access (recordsets, queries, classes, parameters)
7. What is the best way to insert, delete, find and update data?
other topics i have covered approximately. but now i am concentrating on database oriented best practices..
hope now you are very clear about my problem

But, neither he nor you know the answers to these questions ?
1 - who cares ? If you don't know the basics, they are a google away. Anything more than that doesn't matter, certainly to database code
2 - The main thing is to let the .NET connection pool do it's work. Otherwise, no different to any other language
3 - n-tiered is always the best approach, IMO
4 - WHAT ? Have you not used it before ?
5 - resource files
6 - Buy a book on ADO.NET
7 - SQL
