VS 2005 With Winsock - Loss Connection

Nov 7, 2009

my project is attached. I have a very weird problem with Winsock! I made 1 program with 2 forms. 1st form is the client, 2nd form is the server. Server send snapshot for client. So, client display either Single Picture. Or stream of pictures (to simulate video capturing).

when open 1st window (client) in a computer, and 2nd window(server) in another computer... it connect and display picture without problem just once!! when press "Capture" button again it may reponse or Winsock may loss connection. and when Check "Loop"=> means for stream of pictures.. Winsock loss connection immediatly! I don't know where is the problem exactly! The code attached. Winsock ocx is attached.. see it in the release folder


Winsock 2005 - Target Machine Actively Refused Connection

Jun 22, 2009

I am trying to make a client server form application using VB2005. I am using VS2005 Professional for development.

The problem is as follows:
When more than one client tries to connect to the server. The connection is refused and the Client gets an exception in Connect() method - Target machine actively refused the connection.

This problem occurs only when 2 or more clients try to simultaneously connect to the server. For a single client accessing at a time the problem does not occur. The code segment is as given below:

-----------1 Module
Imports System.Net.Sockets
Imports System.Net
Public Class FrmMdiParent
Dim WithEvents wsServer As New Winsock2005DLL.Winsock
Private Sub FrmMdiParent_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
[Code] .....

The above exception is thrown when more than 1 clients try to access the server simultaneously.

VS 2008 Winsock Can't Keep Connection Alive

Jan 3, 2010

I am trying to make a basic server/client program but I ran in a problem.


When I click connect in the GUI the first state of sock.ctlstate is 6 , connecting then the connected event is triggered and after that the sock.ctlstate is 8 , "Peer is closing the connection". But I dont understand why it does this. I should keep the connection alive to communicate.

Loss Of 3d Look In .Net Forms?

Sep 15, 2010

I had a large application that I needed to develop into two separate applications with different customer needs. I created a new VB.Net application and copied/imported all the forms and classes into the new application. The new application works but, for some reason all the forms have lost their 3d look, all the textboxes have a flat look now in the new application. It is as if I have lost a setting somewhere that controls the 3d look of the controls. I have checked the properties of each control and they still have the 3d option selected, and cannot see what else could be changed to get the 3d look back.

System.IO. FileInfo Performance Loss?

Mar 9, 2009

I'm having bizarre performance results of the methods in FileInfo class.I'm using 5 methods of the FileInfo class in the Paint event.The datagridview is bound to the dataset.First the application searches files in the RecursiveSearch. When rows are added to the dataset the Paint event is fired and the rows displayed are filled with extra information from the FileInfo class . In this case the performance is very good. If I remove the DoEvents() from the RecursiveSearch the 5 methods of the FileInfo class become very slow (about 0.25sec for each line of code)!When the search ends, the user can scroll down to see the other files listed.At this point the Paint is again fired. This time the 5 methods of the FileInfo class are again very slow!

Private Sub RecursiveSearch(ByVal sPath As String, ByVal strPattern As String)        System.Windows.Forms.Application.DoEvents()        Try            Dim strFolders() As String = System.IO.Directory.GetDirectories(sPath)            Dim strFiles() As String = System.IO.Directory.GetFiles(sPath,

VS2010 SP1 And SSMS Intellisense Loss

Sep 30, 2011

how many of you out there in the VB.NET community have installed VS2010 SP1 and are experiencing this issue with the loss of intellisense in SQL Server 2008 R2?I'm holding off installing SP1 because I kind of like the intellisense thingy (though RedGate's SQLPrompt 5 is way better - have it at home).So is this pee-ing you off, have you explored workarounds, tries the hotfixes (that apparently don't work for many setups)?url...Please note that even though Cumulative Update 9 (CU9) was released the month there are still people it does not work for..including a coworker using a similar setup as mine (Win7 Pro, x32) This is a disaster and embarassment for MS IMO

It works, but I can see my application memory usage going up by 10kB every 5 seconds until my computer with 6GB of RAm & 64 bit Windows 7 grinds to a halt!

VS 2005 - Odd Occurrence With SQL Connection

Apr 17, 2010

I have a an application that opens a SQL connection and over the course of a few hours creates and disposes of tens of thousands of DataReader objects. You could look at it as just one big loop. As the time goes by, the memory usage steadily climbs until the application/system runs out of memory and crashes.

Psuedo code would look something like
Do Until x =1000000
Create New DataReader
Use DataReader
Close DataReader
[Code] .....

Even though I dispose of the DataReader object when I am done with it, the memory usage keeps climbing. I found that every time I am finished with the DataReader I have to close the SQLConnection and dispose of it. When I do that it keeps the memory usage very low and the processor usage is barely noticeable. I would think I could just open the SQL connection once and close it when I am done.

Connect To SQL Server 2005 Through Wireless Connection Between XP And

Feb 1, 2010

I have built a client-server VB.net inventory application for our company which connects to our Server machine running on Windows XP. We have 6 client machines running also on Windows XP that connects to the Server's database. Now, my problem is, "How do i connect a client machine running on Windows Vista to our Server running on Windows XP wirelessly?"

- Is there something I have to alter on the SQL Server Surface Area Configuration?

-Or do I have to change the 'Connection String' on my software application so as to properly connect to the Server from a Vista mahine? If then, how?

This is the error its throwing:"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)"
