So I know that my code below works. The purpose is to create a tcp Ethernet connection between a scale and computer, so that when a weight is read on the scale, the value is displayed on the computer at the push of a button. I copied this code to a new lab machine that was just imaged for me. As for the winsock, I dynamically created it at run-time by adding it to the references. I understand that this is not what I am supposed to do (see: https://support.microsoft.com/en-us/kb/313984).
With a breakpoint at the CFixPicture_Initialize function, the code hits "set tcpC = new Winsock" line and breaks with error 429: avtiveX componenet can't create object. Does anybody have any ideas as to how I can get this license/get this Winsock control to work? Thanks!
Option Explicit
Private WithEvents tcpC As Winsock
Private Sub CFixPicture_Close()
Set tcpC = Nothing
End Sub
Private Sub CFixPicture_Initialize()
Set tcpC = New Winsock
tcpC.LocalPort = 0
tcpC.Connect "192.168.0.1", 8000
End Sub
Private Sub CommandButton1_click()
On Error GoTo errHandler
tcpC.SendData "S" & vbCrLf
Exit Sub
errHandler:
MsgBox "error:" & Err.Description
End Sub
Private Sub tcpC_DataArrival(ByVal bytesTotal As Long)
Dim strData As String
Dim strDataString As String
tcpC.GetData strData
strDataTrim = Mid(strData, 11)
Text1.Caption = "Weight: " & vbCrLf
The control is not present or is present but not registered on the new machine.
Copy over mswinsck.ocx from your *system directory to the new machines *system directory
Open a console as admnistrator and run regsvr32.exe c:\whatever\mswinsck.ocx
*\System32 or \SysWoW64 on 64 bit Windows.
As there was no license for the Winsock, I found a license online. I simply ran this program and voila! The Winsock worked. Thanks!

I was wondering if it was possible for when you enter a recipient's address for Outlook 2010 to automatically detect this address and change the signature accordingly? Just a general question.
I've had the same question and so far have not found the answer. As a nice workaround, I've successfully used the solution provided here: https://superuser.com/a/228633/74819. In the end you get a button on the toolbar allowing you to create a new message with a custom To address and a pre-defined body text (including signature) of your choice.
Now I actually find this method nicer than what I was looking for because it is more predictable. If the signature (and thus the message body) was changing based on the list of recipients, you would loose control over your text. Also, with a tool of your own, you can set more than just a signature.
Are you looking for a setting to do this or are you willing to work with a macro? If you're open to working with macros, see below and reply back with questions.

'If you are in an Exchange environment, then you can use "last name, firstname"(caps-sensitive).
'If the the recipient is not in Outlook's address list, use "person#email.com"
customSignatureFor = "Lastname, Firstname"
'Use vbCrLf to account for enter/returns
oldSignature = "Respectfully," & vbCrLf & vbCrLf & "Phillip"
newSignature = "v/r," & vbcrlf & "Phil"
If Name = "To" Then
For i = 1 To myMailItem.Recipients.count
If InStr(myMailItem.Recipients(i), customSignatureFor) > 0 Then
tempstring = Replace(myMailItem.Body, oldSignature, newSignature)
myMailItem.Body = tempstring

I'm trying to get Volume Serial Number using Visual Basic 2010,
Is there a whole code example that shows me how to do this?
Thanks
I guess the simplest answer to my question was given by:
Hans Passant:
From his link,
I just copied and pasted this function and it works for Microsoft Visual basic 2010 express, Without any modifications
Public Function GetDriveSerialNumber() As String
Dim DriveSerial As Long
Dim fso As Object, Drv As Object
'Create a FileSystemObject object
fso = CreateObject("Scripting.FileSystemObject")
Drv = fso.GetDrive(fso.GetDriveName(AppDomain.CurrentDomain.BaseDirectory))
With Drv
If .IsReady Then
DriveSerial = .SerialNumber
Else '"Drive Not Ready!"
DriveSerial = -1
End If
End With
'Clean up
Drv = Nothing
fso = Nothing
GetDriveSerialNumber = Hex(DriveSerial)
End Function
I would like to thank everyone for their help,
And i apologize for repeating the question,
I did do a google search and a stackflow search,
But my search was"
"get hard drive serial number in visual basic 2010"
So this website did not show up,
Thanks again
This thread here http://social.msdn.microsoft.com/Forums/vstudio/en-US/43281cfa-51c8-4c35-bc31-929c67abd943/getting-drive-volume-serial-number-in-vb-2010 has the following bit of code that you could use/adapt.
I made a piece of code for you to show all drive information.
The Volume serial number is included you can get that by simple
putting some more if's in the code
Imports System.Management
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim drivetype() As String = {"Unknown", "NoRootDirectory", _

For Each drive In allDrives
Dim win32Drive As String = _
"Win32_LogicalDisk='" & drive.Substring(0, 2) & "'"
Dim Disk As System.Management.ManagementObject _

Problem: Handle the incoming emails using vbscript.
Outlook Version: Outlook 2000
Description: I cannot use VBA for this as I believe Outlook 2000 doesn't let you run a VBA script from the rules wizard and hence I have to use the Run a Program | VBScript method.
What I know: I know how to handle email from VBA like this
Sub Sample(MyMail As MailItem)
Dim strID As String, olNS As Outlook.NameSpace
Dim olMail As Outlook.MailItem
strID = MyMail.EntryID
Set olNS = Application.GetNamespace("MAPI")
Set olMail = olNS.GetItemFromID(strID)
'~~> Rest of the code
Set olMail = Nothing
Set olNS = Nothing
End Sub
I also know how to run the vbscript on the email which is already in the inbox. To run a vbscript in OL2000, you have to use Run A Program and point it to the vbs file. The Run A Script is not available in OL2000.
What I do not know: And this is where I need help. How to get the mail object which has not hit the mail inbox in VBS. Once I get the object then I can do the rest of the necessary operations.
You are correct that OL2000 cannot run a VBA macro from a rule, if this article is to be believed.
Here's how I handle incoming emails. It does use VBA but as far as I know, there isn't a way to do so in VBScript.
Private WithEvents Items As Outlook.Items
Private Sub Application_Startup()
Dim olApp As Outlook.Application
Dim objNS As Outlook.NameSpace
Set olApp = Outlook.Application
Set objNS = olApp.GetNamespace("MAPI")
Set Items = objNS.GetDefaultFolder(olFolderInbox).Items
End Sub
Private Sub Items_ItemAdd(ByVal item As Object)
On Error Goto ErrorHandler
Dim Msg As Outlook.MailItem
If TypeName(item) = "MailItem" Then
Set Msg = item
'~~> do something with the new message here
End If
ProgramExit:
Exit Sub
ErrorHandler:
MsgBox Err.Number & " - " & Err.Description
Resume ProgramExit
End Sub
This code should be pasted into the ThisOutlookSession module, then Outlook should be restarted.
I am trying to update an ancient VB6 project to enable communication with a remote OPC Server. I have installed the Siemens toolkit but I am unable to find any useful documentation on how to use it with VB6. (Works with C#)
The application is very simple. I just need to connect to the remote server and write/read single addresses.
I found the DatCon OCX control which I assume handles the communication but all the ServerName values I tried to enter by hand did not work.
Can anyone help?
Add a reference to the DLL or OCX (the seimens toolkit) to your VB6 project and then use the object browser to browse around the exposed objects. You can often times figure out what you need just be doing that.
The C# docs should also provide a wealth of info. If the library is a COM library, you'll use it essentially the same way from VB6.
Since posting, I did make some progress. The following example helped me to get going.
http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objId=25229521&load=treecontent&lang=en&siteid=cseus&aktprim=0&objaction=csview&extranet=standard&viewreg=WW
Here is my current code. It's not much - just makes contact with the server and tries to write a value. I didn't get any further. I started getting COM errors and assumed the installation was bad (I had had problems installing) so I decided to reinstall. It didn't work. Installation was impossible. Waiting for an upgrade from Siemens.

I'm trying to use Winsock to download some files and save them.
In my case, I have a MSHFlexGrid with 2 columns: one with URL and the other with the "path+filename" (where the file is going to be saved).
I'm iterating through all rows calling the next function:
Public Function DownloadSock(ArqURL As String, ArqDestino As String) As Boolean
'ArqURL is the file URL
'ArqDestino is where the downloaded file is going to be stored, in my hard disc
Dim arquivo() As Byte
Dim ficheiroID As Integer
ficheiroID = FreeFile
On Error GoTo Trata_erro
Open ArqDestino For Binary Access Write As #ficheiroID
Me.Winsock1.Connect ArqURL, 80
Me.Winsock1.GetData arquivo()
Put #ficheiroID, , arquivo()
Close #ficheiroID
DownloadSock = True
Exit Function
Trata_erro:
MDIForm1.Text1 = MDIForm1.Text1 & "Error! " & Err.Number & Err.Description & " - " & Err.Source & " - URL: " & ArqURL & " - Destino: " & ArqDestino & vbNewLine
DownloadSock = False
End Function
I'm getting this error
40006: Wrong protocol or connection
state for the requested transaction or
request
What am I doing wrong?
Have you checked out this Microsoft Support page? It indicates there's a bug in the Winsock control and the hotfix may be helpful.
Another thing to try is to make sure your winsock connection is open before trying to read/send data, and if it is closed, reopen a new connection:
if winsock.state=9 ' error state
winsock.close
while winsock.state<>0 ' closed state
doEvents
wend ' you need a while loop, because it doesn't close "immediately".
end if
' now you reopen it, or do whatever else you need
You might also consider changing your connection code to something like:
With Winsock1
If .State <> sckClosed Then .Close
.RemoteHost = ArqURL
.RemotePort = 80
.Connect
End With
One last thing. Check out this post on using the Winsock control.
I think you have overestimated the power of the Winsock control. You can't just use the Winsock's GetData method to reach out and grab a file. There has to be an active connection between your client application and some other application on the server side. After a connection is established, this server application will feed data to your application, the Winsock's DataArrival event will fire, and then you can use the GetData method to retrieve it. Your code should look more like this:
Public Sub DownloadSock(ArqURL As String)
Dim arquivo() As Byte
Dim ficheiroID As Integer
ficheiroID = FreeFile
Me.Winsock1.Connect ArqURL, 80
End Function
Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Dim ArqDestino As String
Dim arquivo() As Byte
Dim ficheiroID As Integer
ficheiroID = FreeFile
Open ArqDestino For Binary Access Write As #ficheiroID
Me.Winsock1.GetData arquivo()
Put #ficheiroID, , arquivo()
Close #ficheiroID
End Sub
This is far from complete however (nor is it guaranteed to be syntactically correct, consider it pseudo code). After making the connection, you then have to implement some mechanism to tell the server to begin sending the file. If the file is large enough it will take many DataArrival events to get it all, so it will have to be held in an accumulator while the data comes across. There's more to this than you think.
I would take a look at some tutorials and/or sample code (look for a VB6 project that uses the Winsock control on CodeProject, like this one).
