Excuse me for my improper grammar and typos.
It's because English is my primary language, not my first language.
My first languages are C# and Java.
VB, ASP, JS, PHP and SQL are my second language.
Indonesian came as my third language.
My fourth language? I'm still creating it, I'll let you know when it's done!

HI, James my name is, india i am from. I want to make an 'operating system' (like windows 7) with visual basic. i know do not visual basic, i is willing to learn. Time i do not have, and i cannot spend more than day on tis project.

You'll have quite the busy day then...
I think you need to research what an operating system is, and how it works.
Plus, while I have no issues with VB, it's def the wrong tool in this case.

Why do I get the feeling that this is a troll? Doesn't make any sense at all. First you want an operating system, like Windows 7 no less!, and then you can't spend more than a day? An operating system takes months/years of development work, let alone testing, creating device drivers, low level controllers, etc...
Definitely a troll. "KILL HIM!"  I'm kidding! REALLY! Sheesh!

i am no troll. trying to mske an operating system for my friend sanjay. i thought maybe the code project would give help to me as i am a bit of noob

In that case, you have no hope at all of make an operating system in VB6. It simply isn't possible.

One thing you have to realize : building an OS isn't a noob task at all.

You are like kidding right? Operating Systems are not something you can build in a day, a week, or even longer. There is a lot that is involved, just to start File I/O, GUI, Memory Management, etc. Give this food for thought, think about how long all of the major OS manufacturers have been in business and the time it takes to roll out a new product.

It takes them so long because they have to do marketing. The programming usually only takes a month or so

My comment to your post is like others: Your message is funny!
Anyway, to develop an operating system, it takes time. Talking about years. So do plan you need several years to do so.
Secondly, usually I see people using C or C++ to program for an operating system. VB? I am not sure.

Hello:
I´m using TCP client socket in my app. In this case I need to receive data from a device (that is working as TCP server) that is continuosly sending messages without specifying the lenght of the sent data before sending it, it´s like a streaming of binary data. I need to read this data and process some specific parts of the message. The most common references I found about receiving TCP data is using the Stream Read method, but this method requires to define a buffer of defined size. Please read my code below:
Imports System.IO
Imports System.Net.Sockets
Imports System.Threading
Imports System.Net
Imports System.Text
Public Class Write
Public Event DataRecieved(ByVal data As String)
Private Stm As Stream
Private tcpThd As Thread
Public Sub ConnectToServer()
Try
Dim tcpClnt As New TcpClient
tcpClnt.Connect(IPAddress.Parse("192.168.1.50"), 2111)
Stm = tcpClnt.GetStream()
tcpThd = New Thread(AddressOf ReadSocket)
tcpThd.Start()
Catch ex As Exception
MsgBox(ex.Message)
Exit Sub
End Try
End Sub
#Region "Private Methods"
Private Sub ReadSocket()
Dim Buffer() As Byte
While True
Buffer = New Byte(4000) {}
Stm.Read(Buffer, 0, Buffer.Length)
DataRecieved(Encoding.ASCII.GetString(Buffer))
End While
End Sub
#End Region
End Class
You can figure that if I define a buffer of 4000 bytes, I read just 4000 bytes of data sent by the device, but the device keep sending data all the time and I need to keep reading data all the time too, not just 4000 bytes... Is there a way to read data all the time and process this data at the very moment it is received?
Thanks in advance.

There's a comparable example on MSDN[^]. It shows how to receive a variable-length message, which could be a single byte.

You don't have to wait until the buffer is full, in order to use it. From the page on MSDN that I just linked to;
MSDN wrote: This method reads data into the buffer parameter and returns the number of bytes successfully read. If no data is available for reading, the Read method returns 0. The Read operation reads as much data as is available, up to the number of bytes specified by the size parameter. If the remote host shuts down the connection, and all available data has been received, the Read method completes immediately and return zero bytes.
That means that it receives a complete block at once, and it doesn't wait until the buffer is full. It grabs what's there, and it moves on (doesn't arrive a byte at a time, so you'll need to grab multiple). The buffer won't be completely filled, and you have to make sure to get the entire message - how that's done is shown in the example.

Hi,
I am trying to populate access database with a small program in VB; however, getting the syntax error "Syntax Error (missing Operator) in query expression '07/08/2011 12:00:00 PM'." If I remove the date filed in the database, the program works fine. Therefore, the problem seems in the date field.
In access database, the format of the date field is General
Here is the code:
Dim mdate As Date
mdate = "07/08/2011 12:00:00"
Dim cmd As String = "insert into rawClimateData VALUES (" & mdate & ", 12:50 , " & TippingBucket & " , " & Precip & " , " & AirTemp & " , " & SolarRad & " , " & Evap & " , " & windSpeed & " , " & windDirection & " , " & SoilTemp & " , " & SnowDepth & " , " & RH & " , " & BaroPressure & " , " & BatteryVoltage & " , " & SoilMoisture & ")"
MsgBox("cmd= " & cmd)
dbCmd = New OleDbCommand(cmd, myConnection)
dbCmd.ExecuteScalar()
Any help would be greatly appreciated.
Thanks,
Amanjot

For the love of Bobby Tables, don't create a query by incorporating the parameters using string concatenation. Use the Parameters collection. That will also solve your date issue (I am NOT going to tell you how to fix this without the parameters collection).
Also, in any INSERT statement, you should specify which parameters you are inserting, in case the table changes.

Thanks very much for the quick reply. I believe you could sense that I am a rusted programmer. Could you explain little bit on what you mean by parameters collection!!

The link I sent you to shows examples of how to use parameters.
Basically, a SQL query can have parameters. Just like a function with parameters, you pass values to the SQL query... these are parameters. Rather than create the entire query including the values, you can put placeholders where the values go and then pass the command that was created with that parameterized query the parameter values. The link above shows how do do that. Google should be able to answer any more questions you have.

Thanks for the link. It was good to get updated with the parameter collection stuff. You are right, now it makes the code more flexible. However, I still have issues with the date. The program works fine if I don't "insert into" dataTime field but when I include this field, I get syntax error. Any tips for that?
Dim mdate As Date
mdate = Convert.ToDateTime("07/08/2011 12:00:00")
Dim dbCmd As OleDbCommand = New OleDbCommand
Dim parameter As New OleDbParameter()
dbCmd.Parameters.Add("@dateTime", OleDbType.Date).Value = mdate
dbCmd.Parameters.Add("@TippingBucket", OleDbType.Integer).Value = TippingBucket
Dim cmd As String = "insert into rawClimateData (dateTime, TippingBucket) VALUES (" & mdate & " , " & TippingBucket & ")"
dbCmd = New OleDbCommand(cmd, myConnection)
dbCmd.ExecuteScalar()

You are creating the command twice. You are starting to create the command the right way, but then you create it again the wrong way.

Thanks for catching that. I have improved code further, however, still no success. The same error is popping up:
An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll
Additional information: Syntax error (missing operator) in query expression '07/07/2011 11:00:00 AM'.
Here is how the code looks now:
accessDataFile = AccessFileTextBox.Text
Dim connString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & accessDataFile
Dim myConnection As OleDbConnection = New OleDbConnection
myConnection.ConnectionString = connString
myConnection.Open()
Dim mdateTime As Date = "07/07/2011 11:00:00"
Dim Precip As Single = 3.2
Dim TippingBucket As Integer = 2
Dim cmd As String = "insert into rawClimateData (mdateTime, TippingBucket, Precip) VALUES (" & mdateTime & " , " & TippingBucket & " , " & Precip & ")"
Dim dbCmd As OleDbCommand = New OleDbCommand(cmd, myConnection)
MsgBox(cmd)
' Parameter collection
dbCmd.Parameters.Add("@Precip", OleDbType.Single).Value = Precip
dbCmd.Parameters.Add("@TippingBucket", OleDbType.Integer).Value = TippingBucket
dbCmd.Parameters.Add("@mdateTime", OleDbType.DBDate).Value = mdateTime
dbCmd.ExecuteScalar()
