C Sharp :: SQL Server Connection String To Connect Through Domain Name (internet)
Sep 20, 2012
I have tried to connect my sql server 2005 using a domain name. i have bought a domain name and a dns client. this is my connection string
{ SqlConnection sqlconn =
new SqlConnection("user id=user1;" + "password=pass2;"
+ "server=www.mysite.infoServerInstance;"
+ "trusted_Connection=false;" + "network
library=DBMSSOCN;" + "Integrated security=false;"
+ "initial catalog=Mydatabase;" +"connection timeout=5
;"); }
I have added sql browser & sql server in fire wall, and also enabled tcp port 1433 and udp port 1434. the above connection string works perfect when i run it in the server machine, but whenIi try to run it on other machines I am getting an error that server is not available or cannot find the specified server.. I desperately need to access my database through an url. ie., through internet..

I'm getting this error.
SQLite error
near "16": syntax error
On the code:
private void btnUpdate_Click(object sender, EventArgs e)
{
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
[Code]....
With breapoints etc it does show the values it has to insert into my database. But it just doesn't and gives me the Near "16" syntax error.

I am currently writing a small windos form app which relies on an internat connection.
The only issue I have is trying to find out how to force the app to reconnect if the internet drops out without the app crashing. From what I have read I could use "try and catch" but I am not sure how to do this.
The code I have so far is: for testing I am using [URL] as the web site target.
Form1.Designer:
namespace Browser2014
{
partial class Form1
{
[Code]....

I'm strugling to understand why my app is crashing if there is no internet connection.
Code:
int main() {
WSADATA wsaData;
if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0) {
std::cout << "WSAStartup failed.
[Code] ....
Debug crash code:
Code:
First-chance exception at 0x00161831 in ConsoleApplication1.exe: 0xC0000005: Access violation reading location 0x0000000C.
Unhandled exception at 0x00161831 in ConsoleApplication1.exe: 0xC0000005: Access violation reading location 0x0000000C.
It works well as long as the computer is connected to internet but if i disconect from internet the application crash but don't understand why.

I have a problem with my C#. Trying to create the airstrip with planes heading out of the hangars and on to the road to the airstrip. Each Hangar pannel is connected with closes road to them. What i am stuck with right now is connecting the roads together so each one of them will see if the next road is free and if it is it will send the plane (colorder square for now) to it and then proceed to the next one when finaly they will line up for the final panel(airstrip) and take off.So far they are just going down the each road they are assigned with semaphore and thread.
using System;
using System.Windows.Forms;
using System.Threading;
using System.ComponentModel;
using System.Collections;
using System.Data;
using System.Drawing;
[Code] ....
Connecting the "p2" with "p5" so the graphics from "p1" the square will travel through P2 and P5 this would be great and will allow me to procede with my studies.
Also i do realise that this might not be the best ways of using concurrent Csharp and not the up to date one but this is what i have been assigned with and do not have any other options unfortunately.
How i understand this is that i need to have 3 buffers and 3 semaphores for each panel. But i do not know how to add those to each one of them and then connect it with the next one as if i try and add them it either puts a cross in the design view over that panel or says that there is limited options for this statement.
This is the way that i want to do it unfortunately it must be so. The most flexible this can be is by adding an array for semaphores and buffer ( do not know how to do that either).

I have my application database in the AppDataRoaming folder. I'm trying to create a connection string for Telerik reporting, up until now I've had a connection string in a settings class that is put together like this:
The path is:
data source=C:UsersSynlightAppDataRoamingAppNamedataAppDB.sqlite
I've tried files paths like this:
%AppData%RoamingAppDatadataAppDB.sqlite
and
Server.MapPath(@"~App_DataRoamingAppDatadataAppDB.sqlite
(those are not the real directory names, of course). How do I create a connection string that will work on target machines?

I have a submit button, where users are clicking after entering text into textboxes and (hopefully) check boxes (for yes/no).
Here is my code, and when I run it and press submit, there is no action. It just continues to loo.
string ConnectionString = @"Data Source=.SQLEXPRESS;
AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True";
using (SqlConnection dataConnection = new SqlConnection(ConnectionString)) {
using (SqlCommand dataCommand = dataConnection.CreateCommand())
[Code] .....
Note: I took out the Checkboxes in the code to hopefully get a successful run, to no avail.

We have socket server which is developed in c# .net 3.5.
I see server memory keep on increasing whenver client disconnectes and connects.The server disconnects client if client didn;t send valid credentials.
When client is trying to connect with invalid credentials the memory is keep on increasing.
Here is the code that handles disconnection.
try {
if (state.workSocket != null) {
log.DebugFormat("ssl socket displose,{0},{1}", Doomed, IP);
state.workSocket.Shutdown(SocketShutdown.Both);
state.workSocket.Close(1);
state.workSocket = null;
log.DebugFormat("ssl socket displose complete,{0},{1}", Doomed, IP);

I'm getting error ID 10061 - WSAECONNREFUSED - No connection could be made because the target computer actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running.
However, when I use 127.0.0.1 or localhost dns, everything works fine, Im connecting to the ip from [URL] .... with port 1337 ...

I am new to C++ and programming in general. I was wondering if it is possible to use C++ to search for company email formats and domain addresses?
For example, finding the correct format like:
jsmith@carnival.com
or
johnsmith@carnival.com
or
j.smith@carnival.com
Also, if it is possible to find the actual email domain, such as:
@carnival.com
or
@carnivalcruises.com
or
@carnivalcorp.com
