C Sharp :: Server Sending Data Then Client Receive And Store In Database Table In Windows Service
Dec 22, 2014
When server send data then client receive that data, in C# windows services where data receive continuously (Using IP Address and port number) . This below code writing in console application . i want implement same logic in windows service side. but i want data receive continuously.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
[Code]....
Above code write in console application, same logic implementing in windows service, but i want data receiving continuously
ok to start, windows based program, using pelles c ide
winsock2, using "sample" codes, able to connect, BUT no clue what 1/2 of the codes do, and most of the coding is for nix based systems!
trying to understand, and implement a minimal amount of code to add to a current menu based program!
being able to open connection, wait for input from server, receive input, acknowledge the input, then "act" then return to waiting for new input.
or vice versa, server waiting on client (but then server would have to send all the current status`s to client, so that client could be in real time, prob by sending an array from server to client).
I had created windows service .from that i just want to insert data into database . It is successfully installed but it is not started. It gives an error service could not started...
i have to upload a ms access database file to the server from my client program. The server program should connect to this database and read the data. What's the easiest way to upload the file? Is it FTP? i tried sockets, but it only allows like 9kb of data transfer capacity.
I am busy with a project, it is going to consist out of 3 different windows which is logic enough for this whole code to be interactive.
It must be able to pull data into a windows form, displaying it into a textbox, and when you click on the textbox it needs to open up another window where you will have a windows form that will display data as the code loops through the questions in the database.
I am not sure how to push the data that has been selected on the database to the next window..
Here is my code for the first window:
; namespace WindowsFormsApplication1 { public partial class Form1 : Form { //SqlConnection myConnection = new SqlConnection("Data Source=(local);Initial Catalog=KnowledgeEssentials;Integrated Security=SSPI"); //int intType = 0; public Form1()
[code].....
With the second window the data in the table needs to be displayed and each row from the table needs to have a checkbox next to them, so that if the check box is checked, the relevant information of the checked row will show up in the 3rd window... so MY question is, HOW do I pull that data from that specific database and let it show in the listcheckbox?
I have written a windows service which run continuously on a server. Interval time is 9 sec. On timer1_interval i am fecthing record from database and sending it to user. And changing its record status.

I want to write a little c++ program that sends a request to a server an get some data. I found the C++ Rest-SDK and decided to use it. I searched on different websites for code-examples but many of them doesn't work an shows syntax errors. What i got now is that code but the client.request method is skipped. The program never jumps in.

I have a C# .NET Application which get data from QuickBooks via the ODBC Driver and save the result to C# data table. So, I want to transfer this data table to a mysql table on my own server. That's the code I use:

I'll work soon on a program that should take the finger print from a reader and save it in sql server to determine employees's presence and leaving. My questions are:
1- Is the written code differ from one reader to another? or any code apply to all readers?
2- I knew that i should take the image and save it in varbinary in sql server, but how i shall take it?
3- Libraries i should use in visual studio 2010 and c#?
4- should i write license with a definite number of fingerprints save?
5- when i try to approve an employee pressece (by taking his fingerprint), shall i go directly to his id in SQL server and compare his fingerprint stored with the new one entered, OR i Should take the fingerPrint and search for it?
I created a class (let call it X) which contains the structure to store the data from my data base. Them I have a class (call Y) which will contain a list for each row in my data base. Third, I have a class with thousands variables (Z). What I am trying to do is to take the list of objects (Y) that contains the data to initialize Z. What I want to now if I can do something like that.
Imaging that one of my rows contain the following data: Type Nameofvariable etc... "static const double; MNFAIL ; 0; 0; 0,25"
In my list I have a node with contain this data
I want to use the field Nameofvariable to initialize the variable called MNFAIL contained in my class Z.

I need to create a client and server program. The client will have a GUI that will display all the available servers (since more than one will be running) in a list box.
I’m guessing a TCP connection will be the best method here, but how will the client find the servers to connect to? I won’t know the IP address of the server because anyone could take the server program and run it on their computer and the client would have to find it.
Is there some way to make the server send some kind of signal that only the client application will be to connect to? So the server will be sending out a signal, the client finds the signal and connects to the server. Is this possible?
i also need to be able to store the IP address the client selects so when the client application is run again it will automatically connect to the server that was stored.
How to validate the data if the data already exist in the table record in c#?
For example I wanted to add the student roll no. if roll no. is 134 and if we are adding rollno. 134 student then we get the warning like roll no. 134 is already exist ....
I have a Windows desktop application with 2 projects. The main project, and a simple windows service project. I have written the service and the service installer. I have added code to my main window to start the service, but I can't figure out how to install the service when the application runs for the first time, or is installed. Ideally I would like the service to be installed when the application is installed, I'm just not sure how to do that.
