Finding IP Address of Device Connected To PC via LAN Cable.

Hello,

I want to develop an application that can display me the IP address of any device, may it be Mobile or another PC or any device that has an IP address, when connected to my PC via LAN Cable.

for eg. if my PC IP is 192.168.1.1 and another device IP is say 65.62.1.10, then how can i get the device IP address after connecting the device with LAN Cable.

I want to Develop using VB.net, so anyone can help me in this case.

Any idea would be of great help.

Thanks in Advance, awaiting for replies.

You don't know how TCP/IP works, do you?

If you directly connect a device to your PC's ethernet card using a crossover cable, the device you connect has to have an IP on the same subnet as your PC, otherwise, you won't be able to talk to it at all.

Hello,

Dave Thanks For the reply.

I Know What you said is correct, but then that is exactly what my query is.

I tell you, we use one device which is COM to LAN Converter.

Now this device has it's own IP Address, which we can set acc. to our network settings.

Now this device manufacturer has a software where in when the device is connected to the PC, it displays the IP address of the device regd. of whether it matches with network or no.

Also we can then change the IP Address from the software.

So how come this software is able to get the IP Address even if it is not as per our network settings.

Could you give some info. on this.

Thanks In Advance.

Your going to have to ask the manufacturer how the device is discovered. I'm thinking the device might be broadcasting an advertising packet of some kind that the software listens for.

You can see if this is true by using a network sniffer, like Ethereal[^].

[RESOLVED] Trying to use smo to create an insert stored proc which returns identity [modified]

I'm trying to use smo to create an insert stored proc which returns the identity of the newly created row.

Here's my code, which returns a "create failed" message without other relevant details.

(The mMyDatabase reference in the code is a Microsoft.SqlServer.Management.Smo.Database that has been successfully connected to. I can post the code for that part if you need it.)

Public Sub AddInsertActivityStoredProcedure()
    Dim Name As String = "InsertActivityRow"
    If mMyDatabase.StoredProcedures.Contains(Name) Then
      mMyDatabase.StoredProcedures(Name).Drop()
    End If

    Dim An_SP As New StoredProcedure(mMyDatabase, Name, "dbo")

    'An_SP.TextHeader = "???"
    An_SP.TextMode = False
    An_SP.AnsiNullsStatus = False
    An_SP.QuotedIdentifierStatus = False

    An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@UserFK", DataType.Int))
    An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@MachineFK", DataType.Int))
    An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@ActivityDate", DataType.Int))
    An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@Activity", DataType.Int))
    An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@TableAffected", DataType.Int))
    An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@RowAffected", DataType.Int))
    An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@NewPK", DataType.Int))

    An_SP.TextBody = "set nocount on" + NewLine
    An_SP.TextBody = "INSERT INTO [ADV4SQL].[dbo].[ADVActivities]"
    An_SP.TextBody += " ([AcUserFK]"
    An_SP.TextBody += " ,[AcMachineFK]"
    An_SP.TextBody += " ,[AcDate]"
    An_SP.TextBody += " ,[AcActivity]"
    An_SP.TextBody += " ,[AcTableAffected]"
    An_SP.TextBody += " ,[AcRowAffected])"
    An_SP.TextBody += " VALUES"
    An_SP.TextBody += " (@UserFK"
    An_SP.TextBody += " ,@MachineFK,"
    An_SP.TextBody += " ,@ActivityDate, "
    An_SP.TextBody += " ,@Activity, "
    An_SP.TextBody += " ,@TableAffected, "
    An_SP.TextBody += " ,@RowAffected, )" + NewLine
    An_SP.TextBody += "@NewPK= SCOPE_IDENTITY() " + NewLine
    An_SP.Create()

  End Sub

You might want to export to script an existing stored procedure using SQL Server Management Studio first. Take a look at what it output, then you can model your code to create an equivilent string. It doesn't look like adding NewLines at the end of each statement is a valid statement terminator to SQL Server.

Thanks, Dave.
The NewLine was just environment.newline in a var.
I took them off and made sure there were spaces at the beginning or end of each chunk, so that the problem wouldn't be a syntax error.

I did create the stored procedure based on code generated for an INSERT on the ADVActivities table, which has 7 fields including the primary key.

I am new to stored procedures and I can't see how to take the auto-scripted code for INSERT and make a stored procedure out of it.

Is the scripted SQL marked up with anything?? Like Go statements, semi-colons, whatever...??

If I take the .TextBody string that this sub creates, and paste it into SQL Server Management Studio in a new Stored Procedure window, and press "Execute", the stored procedure is created perfectly.

If I run this sub, it fails.

(The mMyDatabase var is populated with a properly-connected database/connection.)

I've tried removing the BEGIN/END items, removing the parameters, changing the .TextMode, the .AnsiNullsStatus, the .QuotedIdentifierStatus, in every combination I can think of, and it still fails.

Thanks for any help!

Public Sub CreateInsertActivityStoredProcedure()

  Dim Name As String = "InsertActivityRow"
  If mMyDatabase.StoredProcedures.Contains(Name) Then
    mMyDatabase.StoredProcedures(Name).Drop()
  End If

  Dim An_SP As New StoredProcedure(mMyDatabase, Name, "dbo")

  'An_SP.TextHeader = "???"
  An_SP.TextMode = False
  An_SP.AnsiNullsStatus = False
  An_SP.QuotedIdentifierStatus = False

  'these are the input paramters
  An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@UserFK", DataType.Int))
  An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@MachineFK", DataType.Int))
  An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@ActivityDate", DataType.DateTime))
  An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@Activity", DataType.Int))
  An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@TableAffected", DataType.Int))
  An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@RowAffected", DataType.Int))

  'this is the output parameter
  Dim An_OutputParameter As StoredProcedureParameter = New StoredProcedureParameter(An_SP, "@NewPK", DataType.Int)
  An_OutputParameter.IsOutputParameter = True
  An_SP.Parameters.Add(An_OutputParameter)

  'start the string (the rest use += )
  An_SP.TextBody = ""

  An_SP.TextBody += "CREATE PROCEDURE InsertActivityRow"
  An_SP.TextBody += " @UserFK int,"
  An_SP.TextBody += " @MachineFK int,"
  An_SP.TextBody += " @ActivityDate datetime,"

RESOLVED !!

Thanks for your help. With a little more research, I was able to find and solve the problem. I found the error in the "InnerException". The error was: "Invalid syntax near 'PROCEDURE'". So I rechecked the sample code and noticed that the sample code did not have "CREATE PROCEDURE" in the .TextBody property.

Answer:
The lines below (marked BAD LINES) are not needed in the TextBody property, since they are actually created programmatically by SMO when the stored procedure is created with:

Dim An_SP As New StoredProcedure(mMyDatabase, Name, "dbo")

As well, the lines defining the parameters are not needed since the parameters are created programmatically by SMO with:

An_SP.Parameters.Add(New StoredProcedureParameter(An_SP, "@UserFK", DataType.Int))

BAD LINES:

An_SP.TextBody += "CREATE PROCEDURE InsertActivityRow"
An_SP.TextBody += " @UserFK int,"
An_SP.TextBody += " @MachineFK int,"
An_SP.TextBody += " @ActivityDate datetime,"
An_SP.TextBody += " @Activity int,"
An_SP.TextBody += " @TableAffected int,"
An_SP.TextBody += " @RowAffected int,"
An_SP.TextBody += " @NewPK int OUT"
An_SP.TextBody += " AS"
An_SP.TextBody += " BEGIN"

and

An_SP.TextBody += " END"

Hi,
I´m looking for control like Corel Draw tool text editor or similar.
Do you know something like this ?

I´m using a Rich Text Box, but the font render is very diferent to font render of pdf library (iText),
( the RTB render text using GDI and iText render text using GDI+ )

I need write text, with any format ( font size, styles...), and then generate PDF document.
( what you see in screen must be identical in PDF )

somebody help me please

thanks!

ClickOnce and Sandbox?

Hi,

My requirement is my Windows application should check periodically for latest updates on some network or web location and users can download only changed files. I found ClickOnce is helpful for this but also I am not sure that it is designed for only sandbox execution/only for current user context or once downloaded, the application can be used by any user on that machine.

My application is going to be installed once on multiple machines on shared way so any user logs on should be able to run it.

How can I achieve this task?

Your ideas please.

Thanks.

hi

i need to split a string ATTATCGATGATATTATTGGTCTTATTTGT into each alphabet..

after splitting each index of the array should hold each alphabet eg. splitseq (0) = A, splitseq(1) = T n so on till the end of the sequence..

FYI its a gene sequence

So you're splitting it into a char array? There's a big hint in that sentence.

Hi poojapande;

You can use the ToCharArray method of the string class as shown in the code snippet.

Dim geneSeq As String = "ATTATCGATGATATTATTGGTCTTATTTGT"
Dim splitseq() As Char

splitseq = geneSeq.ToCharArray()

' Display the splitseq array
For Each ch As Char In splitseq
    Console.WriteLine(ch)
Next
