Hi all. I'm migrating a VB6 application that uses sockets. There is a button that restablishes the connection. In VB6 it is as simple as socket.close and socket.connect, but in vb.net it doesn't work.
I'm using that code to connect:
endpoint = New IPEndPoint(IPAddress.Parse(host), port)
Socket1 = Nothing
Socket1 = New Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp)
Socket1.Connect(endpoint)
The code that works in VB6 is that:
Socket1.Close
Socket1.RemoteHost = host
Socket1.RemotePort = port
Socket1.Connect
The exception I get is: No connection could be made because the target
machine actively refused it
What is wrong here?

Close socket in VB.NET code, before re-connect.

I do that before doing socket1=nothing.
Do you think the problem is in the server? It is not .NET code.

Hi, I had tried that connecting to google ip address but I didn't get any error. please let me know to what server you are connecting. also try the sample by connecting multiple times and reply me please.
EndPoint = New IPEndPoint(IPAddress.Parse("66.249.89.99"), 80)<br />
Socket1 = Nothing<br />
Socket1 = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)<br />
Socket1.Connect(EndPoint)
Thanks,

Ok, it has to be the server. I can connect and disconnect to that IP as many times as I want. My server is VB6 code.

I think the issue here is that the first time you fire a crystal report, the supporting libraries have to be loaded into memory. However subsequent reports load quicker because the libraries are then cached.
As a work around, why not load a simple report at the application start-up?

Hi,
I have added Windows Script Host (COM Component: it's called Iwshlibrary when you add it) to my project.
But, if my program is finished and i want to distribute it, is that still legal because i have imported a library of Microsoft? I'd really like to know that because i don't want to get in any trouble 
Thanks in regard,

I think your connection string is not good.
Try this:
"Provider=Microsoft.Jet.OLEDB.4.0;"
"Data Source=c:\resource.mdb;"
Hope it hepls
|
|
|
|
|
That means I have to change my database, to resources.mdb
Tried that, didnt work

|

why don'you close connection before opening like:
If Con.State = open then
con.close
End if
Thanks & wishes

I tried closing.It tells me that the connection is closed, and then it says, the object con. was not set to an instant of an object.
How do I get around this??

I have question
Why are you using double backslash [ \\foldername\\ ] in connection string write Connection string with single backslash [\foldername\] and
If still problem persist try this for connection string
1] right click on desktop
2] create new text document
3] rename it as mycon.udl
4] double click it and fill proper informations
5] then test connection , if successful then
6] open file eith notepad and copy paste that string

If your DB file name is TryCsharp.mdb, then specify that correctly in conn. string.
I think you're missing mdb extension.

Yeah, so? This is an AWFULLY long way from actually implementing a password. Like I said before, there is NO ONE LINK that will describe how to write NTFS extensions, or teach you C++, or teach you how to use the Windows Device Driver Kit, or the Kernel debugger, or driver debugging techniques, or ...
Just this stuff takes up about 3,000 pages in a set of books...
Oh yeah. In this post alone, I've already given you about 4 search terms to start Googling with.
Don't believe me that this is what it takes to add password support for any file/folder? Look it up yourself. BTW, information on the topic is very sparse because it's ridiculous to do when NTFS already handles a much more robust security scheme.

I think you'll find you need to recurse into each node to find it's children.

Hi,
I have a Device that will be used by dentist to take their paitient teeth pics. this Device is having a click button from which the device takes pics. The Device is configured to my OS using AMCAP device Driver.
I tried capturing the Click event of the Device using WIA 2.0 but using
Dim s As String
Dim dev As WIA.Device = (New WIA.CommonDialog).ShowSelectDevice
For i As Integer = 1 To dev.Events.Count
s = s & dev.Events(i).Name & " (" & dev.Events(i).EventID & "): " & dev.Events(i).Description & vbCrLf
Next
MsgBox("The selected device supports the following events:" & vbCrLf & s)
But the Events I got is of Connected,Disconnected ,New Pic Created and Deleted.
I am not able to find the click event of te device....
Also...Whenever I click on the button on the device the AMCAP driver creates a new window and puts the pic in there...SO I am sure the device is having some Click Event...
Please any one can put some light on this..Mai lme at sshival@gmail.com. This issue is very Urgent.
Thanks in advance
Shival
