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

Hi All!
I'm trying to implement the GetPositionFromCharIndex() statement in my code to work out the cursors position in a Rich Text Box. The Statement that I have written is:
txtEditor.GetPositionFromCharIndex()
I get an error saying that no values have been specified in the GetPositionFromCharIndex() statement parameters.
As I am trying to locate the position of the cursor in the box, I don't know the method of extracting the required parameters for correct use.
How is the GetPositionFromCharIndex() method to be set up, initialized, and used correctly to determine the cursor location?
I've been stuck on this blockage for weeks.  Your help in finding a solution is greatly appreciated.
I'm looking forward to your reply.
Thanks!
Best Regards
Josh

That function takes parameter (an integer). The parameter is the index of the character whoes position you'd like to determine. You want the location of the cursor so the index should be SelectionStart. Your code should look like this: txtEditor.GetPositionFromCharIndex(txtEditor.SelectionStart)
