Call A The Multithread Process In Order To Execute Querry In SQL Server DB?

Sep 3, 2009

I have simple ASP.net web form. With a simple click on a button i need to call a the Multithread process in order to execute my querry in SQL Server DB. I know that my querry willl take up to 45 min to be executed. While the process is running i need to display some status information like: Starting time, Time elapsed, % of completed...So after running the process i got the following error message: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."So i have 2 problems to fix:

Avoid getting timeout while processing/calling the stored procedure. I tried to add cmd.CommandTimeout = 1000 but it didn't work out!
Display correctly Time elapsed and % Completed while processing.

Here's my code in the main form:

Imports System
Imports System.Data
Imports System.Configuration

Multithread Chat Server Side Crash

May 18, 2011

The server connects, the clients connect, one client sends a message to the server, and the server broadcasts it to the other clients. But what I want to do now is to also have the server communicate with the clients. But when I click on the server form, it freezes, and I cant do nothing.

I think this is because of me not creating a thread for the communication(I saw this on another forum), but I dont know how to do that. I copied basically all the chat program code from a site, and I dont know much of sockets and what not.

Windows Service Won't Execute Vbs In Process

Jan 19, 2012

I've been trying off and on for a week now to get this to work but no luck. I have completely stripped down my vb.net 2008 windows service to just create a vbs file and launch it using a process.I'm dying here. The vbs file creates and is valid. I can execute it manually, the windows service just won't run it!! I'm on a windows 7 machine and the process is compiled and installed as a 32 bit process. It is also installed as local system.

After the process tries to execute, I created a text file and it did so successfully. So, I know that the service isn't crashing out.[code]....

Wcf - Execute A Method On An Existing Process Instance?

May 16, 2012

I have a windows service that I have been writing in Vb.Net. As part of this service it calls a class that has a long running Process.I can execute commands to this process when I want to via the ServerCommands() class within the service, however I want to call these remotely. Possibly from a website or click once WPF application.

For this I have used a simple Tcp.Ip WCF example, and have verified it as working correctly.

This called OnStart()Private _serverCommands As ServerCommands
Protected Overrides Sub OnStart(ByVal args() As String)
Add code here to start your service. This method should set things
in motion so your service can do its work.

[Code]...

It appears that in debug _serverCommands is Nothing when it should be running.How might I go about ensuring any command I execute through WCF communicates with the running instance instead of creating a new ServerCommand() instance??I haven't tried WCF before, so I might be hitting a dead end... however I'm sure its possible.

VS 2010 Dataset Created A New Process In Order To Run An Exe And Pass

Jul 20, 2010

I am writing an application that is doing a file conversion.I created a new process in order to run an exe and pass it some arguments in order to do the file conversion. I ran this in the Submit button click event.I added an event handler for when the Process had exited and then continued my code, since I had to wait for the file conversion to complete before continuing.

Everything is running fine now up until the point where I am trying to call a FillBy for one of my datasets. My fill by is accepting a parameter UserID and filling it based on the user id, which is selected in a combo box in the program itself.I keep getting exceptions and it immediately exits the program whenever I try and use this fillby method, if I take it out it completes successfully; however, the new row I just inserted was not added.

I tried adding a tryparse for the value selected from the UserID combobox but I get this cross-thread exception, so I have a feeling the 2 are related.

SQL Server Stored Procedure And Execute

Apr 29, 2012

This is a bit old-contents to be discussed but I need someone who can explain me how to create stored procedure in SQL Server for returning a value from procedure, example:[code]Then I need the name of its customer and the address instead.I need to make it as a stored procedure and show me how to execute it on VB.NET. Perhaps we assume that the name will be prompted to LABEL1.TEXT and the address will be prompted to LABEL2.TEXT. I've improved this SQL-Server Stored Procedure Using return but I have nothing to return after I execute it.[code]

Server - Data From TCP Client Isn't In Order

Nov 12, 2011

I've been working on this project for about a year now. It's a basic clientserver chat program. After a long time of improvement, I decided to test out the strength of my server.

On the client, I fired off 200 chat messages ("FLOOD# 1"... "FLOOD# 200") to the server as fast as possible. The result: Server immediately crashes. After some slight tampering, I was able to get the server to process 135 of the 200 messages before giving up. It no longer crashes, but something different happens. The data from the client is received in order, but when I pass that message to a function (myForm.OnLineReceived), The data is completely out of order. If I add a slight delay between the calling of the OnLineRecieved function, The messages are in perfect order.

Each message from the client is first encrypted, then encoded in base64. An "-" is appended to the end so that the server can easily find the end of each data "packet".

Server Code:

Imports System.Net.Sockets
Imports System.Text
' The UserConnection class encapsulates the functionality of a TcpClient connection
' with streaming for a single user.

Possible To Call .exe Files With Shell() Or Process.Start()?

Aug 8, 2011

I have an issue in my project I am programming in both Matlab (Matlab2011a) and Visual Basic (VS2008).I've created a .exe file from my matlab code. It works well when I click on it with my mouse.But I need to run it within Visual Basic. I know it's possible to call .exe files with Shell() or Process.Start(), and it works well for files such as firefox.exe or notepad.exe. However, it doesn't work when I call my own .exe file ...It's weird because when I look to the Task Manager while trying to call it (within VB), I can see the process starting and ending, but its output doesn't appear.

Communications :: Execute Command Remotely On Server

Mar 16, 2010

I have been searching for a good code example that will place a small server program on my server and then allow me to use a client on my pc that will tell the server program to run a batch file on the server.

I thought this would be simple... I am finding it not that easy.

We have a server that users need to execute a command on however we do not want them to have login rights to the server so this will allow them to execute the batch file without having to log in.

Asp.net - IIS Application Pool Crashes When Using Context.Server.Execute?

Apr 13, 2012

I am having an issue with an ASP.Net page I am writing and struggling to diagnose why this page is failing.

I am trying to do this:

Dim st As New StringWriter()
Dim strURL As String = "CourseProgramme.aspx?id=3733"
Context.Server.Execute(strURL, st)
txtNotes.Text = st.ToString()

The aim here is to get the HTML back for the page that has been specified in strURL and then display it in a textbox. However when I run this code it crashes the ApplicationPool in IIS and when I look in event viewer I see this error message:

A process serving application pool 'blueprintdev' suffered a fatal communication error with the Windows Process Activation Service. The process id was '5284'. The data field contains the error number.The strange thing here is that in another page I do this code which works fine:

Dim strDutyStartDate As Date
strDutyStartDate = TextboxDutyStartDate.Text
Dim st As New StringWriter()

[code]....

As far as I can see other than the URL I am passing, which does exist, I cannot see a difference between the two.The page I am developing is in ASP.Net with .Net 4.0 however in the website there are some classic ASP pages. IIS is running at version 7.5.7600.16385 on Windows Server 2008 R2 64Bit.So far I have tried setting the application pool to run in 32bit mode but that causes errors in other areas and the site will not load.
