Update Server Program When Client Program Added Record To Database?
Aug 18, 2010
I am creating a very simple Voting System, that will be use on electing new set of officer in a teacher cooperative...
So I have to create two separate program, a Server Program that will manage all the information in the election and a Client Program where voters will vote their selected candidate...
The election officers wanted that the Server Program will display the Voting Results at real time... So when the Voter finished voting, The Voting Result displayed by the Server Program will also be updated every time the Client Program Insert the data to Database....
An action listener in Server Program that will execute if new data is inserted in a Table in the Database made by the Client Program...
I'm developing a remote control program that uses a mysql database as the bound beetween the server and the client.The only problem is that cause of mysql being really varnuable to crashes i made it in a way that it checks for information every 10 seconds so things doesnt get messy. [code] For some reason after 10 seconds the connection is mysteriously aborted and the reader gives a fatal error.How can i extend the time limit to >10 seconds ?
I'm trying to generate a query dynamically using textbox values from my Bookings form to update only those values that were entered by the user.[code]...
I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.
The problem I have is: When I click on cmdListen in the server form and cmdConnect in the client form,both programs won't respond and they crash for some reason I don't know.
Client source code:
Code:
Imports System.Net.Sockets Imports System.Text Public Class Form1

I have been working on a project which is used by a company's sale team, to combine all the wanted input data in one place allowing the sales team to show customers, where switching to them could save them money.
Basically what i want is a program which can save single records, which can hold data added in other text boxes, or indeed take the data from the list view boxes which is the intended output. I want to be able to save that data, then be able to Open it up again at a later date, and even modify it.
enabled me to save the three ways to identify a single record, the index number, company name and the date it was added. However I now need a way to save the data entered in my other forms to these single records.
I made a simple TCP server (I've found the example on the web) in VB to receive data from about 40 TCP clients.The clients are not synchronized but sends data about every 18 minutes; the problem is sometimes several clients sends data at the same moment, so I can't receive data.I also made a second program that reads the data (server program writes data on a file, read from the second program) scheduled.
My question is this: I've seen on the web examples about Multithreaded Server Socket Program, so I suppose this could manage my 40 clients (but now the clients are syncronized and send data at the same time in client mode) or is better get data (I have a central client that asks data to all 40 devices in server mode)?
Second question: can I make a single program where I run both TCP client and TCP server at the same time?
I have been working on a server and client tcp/ip program and am having some issues. I start the server and then start the client, and the connection always fails. I don't know what's going wrong. Here's the
I have been a web developer for a number of years now and I am making the move over to form based applications. I am trying to do what I believe should be relatively simple, yet I have no idea where to start.At home I have a machine that family members tend to use P2P programs, which causes my online gaming to suffer with glitches.I want to create a server and client program.where the client app (on my laptop) consists of only one button, when the button is pressed I want the server app (my Desktop) to kill the P2P program.I already know how to kill/start the application in question.I have previously done something similar but I had used winsock (not in VS2010) and was a long time ago.
1) Sending a value/string from the client app
2) receiving the value/string on the server app
I was told to look into the system.net.sockets namespace, but I haven't found anything on the web or here that isn't a full project / over-engineered "Basic Tutorial" that helps to break this down
I Want To Create A Server Program On My Computer AndClient Program That Can Run On Other Computers, The Client Program Will Connect To The Server On My Computer, But I Don't Know Code To Do This.
I am trying to create a server/client program in vb.net. What I am trying to do is test a battery that is running on a handheld (which runs Windows CE 5) by connecting to a "server" and sending information every 10 seconds or so. I am very new to .NET, and am not really sure how to go about doing this. I want two separate applications running, with the server-side keeping all of the data, since the battery is going to die, and I will lose any information if I keep it client-side. I am also new to networking, so I was not sure of whether I should create a Socket, or if I should try to do something else.
i made a program that uses sockets to connect the server to client but there is a problem with it when i try it on this ip"127.0.0.1"wich is not a real ip just a loopback to my computer it works just fine when i use my local ip it works as well when i use my main ip from http:whatsmyip.org it doesnt work at all i dont know why it doesnt say an error or an exception but its not connecting so i gave the server to a friend of mine i tried using both his real ip and his local but still not working i dont know why?i mean i am 100% sure of my code...
The client would need to be able to communicate with the server for several simple tasks, such as checking if the file on the client is different from the file on the server. Or issue a "create folder" command. And of course the file transfer itself.[code]...
I'm trying to make a Client that will automatically run a .DLL that I have created and send information over port 80 to my Server program that will take that data and import it into a database for me. Problem is, I don't know where to start as I have never done this before. I want to do this in VB .NET as this is the programming language that I know. What are methods of doing this? Is there sample code out there for something like this? My google searches are failing me.
A better layout of what I'm trying to do:1. Client Runs .DLL, retrieving information from an Excel file.2. Client takes these properties with the data it contains and sends it to a program outside of the local network through port 80, my boss refuses to let me use any other port.3. Server accepts the data and builds its own properties to be imported into my Access Database.4. Repeat over, and over, and over, and over.
I plan for the server application to be a console application, and the client to be a windows form.
I am trying to code a client - server program. I have 4 winsock controls on my main form. The client is able to connect to a free one just fine, and can figure out if they are all in use. When testing my program, I found that when I try to send data through a socket, then send different data directly after, it jumbles the data together.
CODE:
That is the code I am using. When the client is connected to the server, and ready for data, it sends the packet "@Ab". When the server receives this packet, It is supposed to send the welcome alert, and then current events posted in the server.
On the client side, there is a message box that is supposed to show the welcome alert, and at the bottom on a status strip, the current events are supposed to be listed.
When the welcome alert shows, it contains the alert text fine, but then shows the packet for the events after it.
I am Working on Teghax Component.Using This Component we want to find out Block title attribute of dwg file in a client server socket application.
1> We get Block title attributes properly of dwg file in windows application form using the getattribute function().
2> We get Block title Attributes properly in that way:-We take a class library where we take a class.in this class we use getattribute function().Then We access the particular class from another project
But when we use the same class(Keep same structure) in client server socket program.Then it gives an exception.i.e ,"Spaicfied cast is not valid"I am Not getting any reply form teghax developer..I attached exception screen sort.Give me Suggestion How to solve this Exception
Code given Bellow :
Public Function Get_DwgFileAttribute(ByVal Sender As ClsTcpConnection, ByVal msgTag As Byte, ByVal message As String) As String Dictionary = GetHashtable(message) Dim varfilepath As String = CStr(Dictionary.Item("filePath"))
I have a access database with these columns. USER_ID,COUNT,TIMES
Let say the current record is this: USER_ID,COUNT,TIMES STEVE20,24,1.5
Now I want to updated the current count record and times, but before updating I want the old record to be added to the new record. What should be my query?
i an encounting this problem that is...my database is unable to access in client pc and its comes out this error: cannot open database "synonym" requested by the login.The login failed. Login failed for user 'SIDNEY-U1KECH4Tsidey'.
I'm trying to create a program, that upon opening, will read an input file containing a delimited employee record. The record will contain the name of the employee, their salary and the number of years they have been employed.I'm looking to display only the name of the employees in sorted order(alphabetically) and then when the user of the program selects a particular employee, I want to display the salary and number of years for that employee.I would like the user to be able to edit the recors for the employee and I would also like to have a way for the user to be able to add/remove an employee record and update the input file before the program is closed.
This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields
I have tried many different suggestions from numerous posts by other people but with no avail. So I figured I would post "my" code and see if someone could lean me in the direction I need to go. I just need to update my database with the given values but when I click the Update button on my form It keeps telling me there is a syntax error which I do not see.[code]...
