Error code = 0x8007000b In MS connect this is reported as a bug but MS is unable to reproduce the problem altough when you search the fora I'm not the only one with this problem. So any help is appreciated.

• Windows 8 unable to connect to WPA2 AES Wireless Network

  - by user170193

  I'm running Windows 8 and am unable to connect to my home wireless network. I've tried restarting the router, patching the drivers to the next version, patching the drivers to the last version, running windows update and patching the chipset drivers to the latest version. So far nothing has worked. My computer can get on the internet via USB tethering on my phone or an open WiFi connection, but it is unable to connect to my home WPA2 AES secured wireless network. It sees the network, attempts to connect, gets a limited connection and then drops the connection. All the other wireless devices in my household have no problems. I have the new Dell XPS 12, running Windows 8 using an Intel Centrino Advanced-N 6235 wireless adapter. I've refreshed windows twice now to try different driver configurations. I've tried uninstalling all the Dell software, I've tried uninstalling all the Intel software and reinstalling just the drivers. I've tried turning switching the ability for the Wireless driver to turn the computer off or on. I've tried setting up the connection manually from desktop mode. I've tried switching it on and off using the wireless button on the keyboard and in the software. So far nothing has allowed me to connect to the secured network. It just keeps getting a limited connection, dropping the connection and retrying. It's driving me crazy, any ideas, anything I missed? Thanks.

• Vista ICS issue

  - by Bill Grey

  I have a strange problem with Internet Connection Sharing on a laptop running Vista Business. This laptop is connected to the internet via the ethernet port, which goes to an ADSL modem. it is automatically assigned the IP address 192.168.1.50, and the modem/gateway is 192.168.1.1 My friends laptop is running Vista Home. Previously, I would create an ad hoc wireless network, enable ICS, and everything would be perfect. My friend would have internet access via this. However, something has now mysteriously broken. If I enable ICS on the wireless connection, it resets my Local Area Connection, assigning it the manual IP address of 192.168.0.1, which means my connection to the internet is destroyed. Both wireless adapters on each network are assigned auto configuration addresses, in the 168. range. They can see each other fine, but my friends laptop cannot access the internet via mine, even after I have restored the Local Area Connection settings. I understand the computer with ICS enabled must have the IP of 192.168.0.1, but previously, before whatever went wrong, my wireless adapter would be 192.168.0.1 and my friends computer would get an IP via DHCP. I have also tried setting static IP address and making a bridge, none of which works. How can I fix this problem, and prevent enabling ICS from touching my Local Area Connection? Both machines have no firewall, have appropriate settings etc...

• Unable to add datasource in ColdFusion 9 and SQL Server 2008 R2

  - by Evik James

  I just installed SQL Server 2008 R2 and ColdFusion 9.0.1 on my Windows 7 machine for development use only. I have ColdFusion running well and serving pages (that aren't connected to a database). I can view my databases in SQL Server Management Studio. I successfully restored a few small databases and now I am trying to set up datasources for them through the ColdFusion Administrator. On my other machine, this was super easy. Not so much this time. The database I just added is named "Test". I am getting this error: Connection verification failed for data source: Test java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: localhost:1433. Reason: Connection refused: connect The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: localhost:1433. Reason: Connection refused: connect It looks like the connection between ColdFusion and SQL Server is being refused. I know, brilliant observation, right? On my other machine, I was able to create datasources with just the default settings, no server name, username, or password. Any clue as to what might be the cause and how I might fix it?

• Can I attach a VPN firewall to an existing network and have it manage VPN connections?

  - by jules

  I'm quite new to networking and am trying to set up my first VPN connection. The Situation: I have been contracted for some programming at a facility some distance from my location. I would like to be able to set up a simple VPN connection to their network so that I may make adjustments without significant travel. Their Current Network: Six devices (one I need to connect to) plugged into a basic router (Dlink). This router has an internet connection and a static ip address. My Hopeful (questionable) Proposal: I attach a VPN Firewall I happen to own (Netgear FVS318) as device number seven on the client network. I disable routing / DHCP in the Netgear. I forward the appropriate IPSec ports from the Dlink to the Netgear. I then create a VPN connection on my office Windows 7 machine to the remote network. The request is forwarded from the Dlink to the Netgear where the VPN connection is authenticated. I now have a remote-access connection from my office PC to the client's local network. The Question: Will this proposal work? If not, would another possibility be to attach a computer with a VPN server to the client network? Also, as a note: the client has requested I not replace their router or place mine in-between theirs and the internet :( Thanks very much!

• Cannot access certain URL on my wireless

  - by dehmann

  Problem: On my wireless network at home, there is one URL that I just cannot access with my browser: http://research.microsoft.com/ I have no problems with the Internet connection otherwise. But on that address I just get The connection was reset The connection to the server was reset while the page was loading. from Firefox. I am using a DSL modem (Westell) and Linksys wireless router (using DHCP). When I use my neighbor's wireless connection I can access the microsoft site without a problem.

• OS X won't see Windows 7 in network (and vice versa)

  - by meds

  I've enabled SMB sharing in OS X Lion and have added folders to share, it says 'Windows Sharing: On' with a green circle next to it (from the sharing window) and that to access the volume I will need to to go to \\192.168.0.17. It also says that the OS X should be visible as 'macbook' in the network. Both my WIndows 7 and OS X are connected to the same network, yet when I try to go to \\192.168.0.17 or from the Mac try to go to my Windows system (smb://192.168.0.6) the two OSs don't see each other. Any ideas why? Attempting to ping the Mac from Windows results in this output in the command prompt: Pinging 192.168.0.17 with 32 bytes of data: Reply from 192.168.0.6: Destination host unreachable.

• Apache Logs - Not Showing Requested URL or User IP

  - by iarfhlaith

  Hey all, I'm having a problem with a server that keeps falling over. Looking through the Apache error logs it appears to come from a rogue PHP script. I'm trying to track this down using Apache's error_log and access_log but the server log format isn't giving me the detail I need. I suspect the log format isn't sufficient, but I've reviewed the Apache documentation and I've included the switches that I think I need to see. Here's my LogFormat configuration in the httpd.conf file: `LogFormat "%h %l %u %t \"%r\" %s %b %U %q %T \"%{Referer}i\" \"%{User-Agent}i\"" extended CustomLog logs/access_log extended` Using the %U %q %T switches I expected to see the requested URL, query string, and the time it took to serve the request, but I'm not seeing any of this information when I tail the log. Here's an example: 127.0.0.1 - - [01/Jun/2010:14:12:04 +0100] "OPTIONS * HTTP/1.0" 200 - * 0 "-" "Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 (internal dummy connection)" 127.0.0.1 - - [01/Jun/2010:14:12:05 +0100] "OPTIONS * HTTP/1.0" 200 - * 0 "-" "Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 (internal dummy connection)" 127.0.0.1 - - [01/Jun/2010:14:12:06 +0100] "OPTIONS * HTTP/1.0" 200 - * 0 "-" "Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 (internal dummy connection)" 127.0.0.1 - - [01/Jun/2010:14:12:07 +0100] "OPTIONS * HTTP/1.0" 200 - * 0 "-" "Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 (internal dummy connection)" 127.0.0.1 - - [01/Jun/2010:14:12:08 +0100] "OPTIONS * HTTP/1.0" 200 - * 0 "-" "Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 (internal dummy connection)" 127.0.0.1 - - [01/Jun/2010:14:12:09 +0100] "OPTIONS * HTTP/1.0" 200 - * 0 "-" "Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 (internal dummy connection)" Have a made a mistake in configuring the LogFormat or is it something else? Also, each request appears to come from the localhost. How come it's not giving me the remote user's IP address? Thanks, Iarfhlaith

• SQL server agent job to execute SSIS package fails, package succeds if run manually

  - by growse

  I've got a SSIS package installed on a SQL server (SQL Server 2012). It's fairly simple and just fetches data from a remote data source and adds it into a local table. The remote connection string is using SQL server authentication, while the local connection is using Windows auth. The remote connection password is protected, and the package was imported setting the protection level to Rely on server storage and roles for access control. If I run the SSIS package manually, it works. If I run it from the command line using dtexec, it works. If I use runas to switch to the domain account that the SQL server agent is running under, and then run the package using dtexec, it works. If I create a SQL Agent job with a single step to run the package, it fails, providing very little detail as to what's going on. I'm guessing it's not able to get the password to log into the remote SQL server, because it fails very quickly. Also, if I tick 'log to table' and view the resulting file, I get the following: Description: ADO NET Source has failed to acquire the connection {0D8F2CD4-A763-4AEB-8B52-B8FAE0621ED3} with the following error message: "Login failed for user 'username'.". If I try to add the password in the connection string manually under data sources in the job step dialog, it refuses to save it, always seeming to remove the 'password' bit of the connection string. I thought that SQL server agent jobs always ran under the context of the account which the SQL server agent is running under. This account is a sysadmin on the local SQL server, and the package works using dtexec under that account, so why would it fail when trying to run as an agent job?

• port forwarding with socks over proxy

  I am trying to browse a wiki that runs on a server inside one domain from another domain. The wiki is accessible only on the LAN, but I need to browse it from another LAN to which I connect with an SSH tunnel ... Here is my setup and the steps I did so far: ~.ssh/confing on wikihost: Host gateway User kisteuser Port 443 Hostname gateway.companydomain.com ProxyCommand /home/myuser/bin/ssh-https-tunnel %h %p # ssh-https-tunnel: # http://ttcplinux.sourceforge.net/tools/stunnel Protocol 2 IdentityFile ~/.ssh/key_dsa LocalForward 11069 localhost:11069 Host server1 User kisteuser Hostname localhost Port 11069 LocalForward 8022 server1:22 LocalForward 17001 server1:7100 LocalForward 8080 www-proxy:3128 RemoteForward 11069 localhost:22 from wikihost myuser@wikihost: ssh -XC -t gateway.companydomain.com ssh -L11069:localhost:22 server1 on another terminal: ssh gateway.companydomain.com Now, on my companydomain I would like to start firefox and browse the wiki on wikihost. I did: [email protected] ~ $ ssh gateway Have a lot of fun... kisteuser@gateway ~ $ ssh -D 8383 localhost user@localhost's password: user@wikiserver:~> My .ssh/config on that side looks like that: host server1 localforward 11069 localhost:11069 host localhost user myuser port 11069 host wikiserver forwardagent yes user myuser port 11069 hostname localhost Now, I started firefox on the server called gateway, and edited the proxy settings to use SOCKSv5, specifying that the proxy should be gateway and use the port 8383... kisteuser@gateway ~ $ LANG=C firefox -P --no-remote And, now I get the following error popping in the Terminal of wikiserver: myuser@wikiserver:~> channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused Confused? Me too ... Please help me understand how to properly build the tunnels and browse the wiki over SOCKS protocol. update: I managed to browse the wiki on wikiserver with the following changes: host wikiserver forwardagent yes user myuser port 11069 hostname localhost localforward 8339 localhost:8443 Now when I ssh gateway I launch Firefox and go to localhost:8339 and I hit the start page of the wiki, which is served on Port 8443. Now I ask myself is SOCKS really needed? Can someone elaborate on that ?

• TCP Server Memory management: #Connections Vs. #Requests

  - by Andrew

  Given that, there is no theoretical limit to number of concurrent TCP connections a Windows 2008 server can handle. Only thing will happen is, with each connection there will be memory consumption in server. Unfortunately, memory is not unlimited (and I want to utilize only physical memory). For example, lets say we've 2GB server memory. Now there are two extreme cases: Case 1: If we've allocated 64KB buffer for each connection (only to receive incoming request), then 32768 connections can consume all the 2GB of memory. This will not leave any memory to queue/process incoming requests from those connections. Case 2: On the other hand, lets say a single (or very few) connections continuously keeps sending request buffers (for example, video streaming from one connection to other) and server cannot process them within time, those buffers will get piled up in server and eventually will occupy most of the servers memory. And it will not leave any memory for new connection thereafter. This is the real dilemma in server design bugging me badly for last many days. If I can decide on max size of request buffer per connection and max number of requests to allow in queue per connection. Then, based on available server memory, it will then automatically set limit on max number of concurrent connections. How to decide on these limits to achieve best performance and throughput? I am just looking for perfect utilization of server resources. Are there any standard guidelines or empirical data available with someone who can share with me please.

• OS X (10.6) Apache Sudden Death, Nginx not working either...

  - by Jesse Stuart

  Hi, I turned on my computer today and apache wasn't working. This is weird as its been working for the last 6 months without issue. The only thing I did which may of caused a problem, is I uninstalled a bunch of gems. This shouldn't be the issue though as apache doesn't rely on gems. I decided to give nginx a try to see if it would work and have the exact same issue. The symtoms are: I go to http://localhost and get the browsers default 404 page (not rendered by apache/nginx) No error is found anywhere (I checked all logs) Apache is rinning (also tried with Nginx) How can I debug this to find the root of the problem? I can't think of why this would be happening. I've tried repairing permissions in case this was the issue, apparently it wasn't. Everything was working the other day, and nothing changed in the apache config. Update: Here is the output of telnet localhost 80 $ telnet localhost 80 Trying ::1... telnet: connect to address ::1: Connection refused Trying fe80::1... telnet: connect to address fe80::1: Connection refused Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host

• What is going on when I can't access an SMB server share (not accessible error) until I run cmdkey to delete the credential?

  - by Warren P

  I have a network connection share issue. The first connection works, and seems to stay connected for at least a few hours. However, after each time my windows 7 PC reboots, it can no longer form a network connection to the shared folder, nor browse to it, until I not only unmap and remap the mapped drive, but also, I have to use cmdkey to delete the stored credentials like this: cmdkey /delete:Domain:target=HOSTNAME My work PC is on a domain, and I am not the IT administrator, but I'm curious if there is anything I can do to investigate this issue. Any settings in registry or group policy that I could examine to see why the first connection works, but each subsequent attempt (once a stored credential exists) to browse or use the connection, fails with a connection error saying it is "not accessible", like this: I do not even get any error until at least several minutes go by. THe first thing I see is a window frozen and empty, and then I get this error: This has happened when connecting to a share on a DROBO device, and on a share which is not on the domain, but which was a Microsoft Home Server. I wonder if there's something broken in WIndows 7 professional with regards to connecting to non-domain shares when an active directory domain controller exists, and a particular workstation is joined to a domain? The problem only occurs if I click "remember credentials". It is not fixed by any amount of working with net use. Usingcmdkey to delete all stored credentials for the host is the only way to get back in, and it affects all non-domain shared folders. Update I'm hoping there are some registry locations I could check that could be misconfigured in some way that might explain why SMB/CIFS stored credentials for non-domain systems seem to be auto-invalidated in this weird way. Knowing how whacko Microsoft Windows domain and security handling is sometimes, this could be some kind of stupid "feature".

• Hybrid Exchange Online setup with on premise public folders, certificate issues?

  - by exxoid

  We have a Hybrid Exchange setup with Exchange Online (v15 tenant) and Exchange 2010 on premise. The hybrid configuration for the most part is working, what I am having an issue with is getting public folders to work for cloud users. I followed the official documentation here (http://technet.microsoft.com/en-us/library/dn249373(v=exchg.150).aspx) and it kind of works. When I am accessing Outlook on a public wifi I am able to bring up the cloud mailboxes and on premise public folders show up in Outlook. When I am accessing email via Outlook as a cloud user on the same LAN as the on premise exchange, the cloud user makes the outlook.com connection for live/ad/archive mailbox but fails to create a proxy connection for the on premise public folders. The error I get is a certificate mismatch, it seems that when a user on the LAN accesses Outlook/Exchange it is using a different certificate vs. when Outlook is launched on a WiFi network. When I look at the Outlook connection information, I see the connection to outlook.com for ad/live/archive mailbox but no entry for public folder connection. Our on premise Exchange is 2010 SP3 with latest CUs. The client is a domain joined laptop with Windows 7 and Office 2010 SP2, latest windows updates applied. Our infrastructure has a working ADFS 3 and DirSync setup for Office 365. My question then is, what do I need to do to make sure that the Cloud user launching Outlook on the LAN uses the proper certificate (the wildcard 3rd party cert.. vs. the self signed certificate which it looks like it may be using during the connection attempt).

• Legacy VB6 application under Win7 SQL error

  - by Shial

  We have a rather unfortunate legacy application at work, written originally in VB6 it predates anybody in our IT department by at least 5 years. We have a contracted developer for ongoing maintenance and where he can he rewrites sections over into .NET code (Not sure about his techniques here, this is a side job for his regular work as an IBM engineer) the application works fine (such as it is) under windows XP. We have only a couple of Windows 7 machines mainly for testing and this application seems to run into a wall. Things like the background not loading and SQL errors. This is even running under administrator. Running an SQL trace from the ODBC control panel shows several interesting things. It makes a connection to the database successfully initially where it runs a query to determine if it is running the correct version. This query works fine. 558-1af0 ENTER SQLExecDirectW HSTMT 0x020D7548 WCHAR * 0x04C8F0F0 [ 115] "SELECT count(*) c FROM tblSoftwareVersion WHERE fldSoftwareVersion = '123456' AND fldSoftwareName = 'Application.VB'" SDWORD 115 BMS 558-1af0 EXIT SQLExecDirectW with return code 1 (SQL_SUCCESS_WITH_INFO) HSTMT 0x020D7548 WCHAR * 0x04C8F0F0 [ 115] "SELECT count(*) c FROM tblSoftwareVersion WHERE fldSoftwareVersion = '123456' AND fldSoftwareName = 'Application.VB'" SDWORD 115 It then seems to drop its connection and can't find the ODBC connection despite the fact its connecting to the same DB. From the trace it looks like it configures the connection then it starts firing off SQLFreeStmt to unbind and close out then when in the application and it tries to do its thing there is no connection. 558-1af0 ENTER SQLFreeStmt HSTMT 0x020D7548 UWORD 2 <SQL_UNBIND> BMS 558-1af0 EXIT SQLFreeStmt with return code 0 (SQL_SUCCESS) HSTMT 0x020D7548 UWORD 2 <SQL_UNBIND> Then this happens when I try to do something that pulls data 558-1af0 ENTER SQLDriverConnectW HDBC 0x020DDA00 HWND 0x00000000 WCHAR * 0x73EF8634 [ -3] "******\ 0" SWORD -3 WCHAR * 0x73EF8634 SWORD -3 SWORD * 0x00000000 UWORD 0 <SQL_DRIVER_NOPROMPT> BMS 558-1af0 EXIT SQLDriverConnectW with return code -1 (SQL_ERROR) HDBC 0x020DDA00 HWND 0x00000000 WCHAR * 0x73EF8634 [ -3] "******\ 0" SWORD -3 WCHAR * 0x73EF8634 SWORD -3 SWORD * 0x00000000 UWORD 0 <SQL_DRIVER_NOPROMPT> DIAG [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) Nearly all of my searching on this issue comes up with programming issues where the connection string has a problem. The only thing that is different in this particular scenario though is Windows 7, I know the connection string is fine since it works on the XP machines. The VB components are supposed to be still functional under Win7. My computer is running 32 bit win7 and my VP is running Win7 64 bit and both have the same problem so that can be ruled out. I have already tried reinstalling the SQL Native Client and the VB runtime as well as the application in question. Hopefully I can find a solution and not have to resort to using the XP VM.

• Does writing data to server using Java URL class require response from server?

  - by gigadot

  I am trying to upload files using Java URL class and I have found a previous question on stack-overflow which explains very well about the details, so I try to follow it. And below is my code adopted from the sniplet given in the answer. My problem is that if I don't make a call to one of connection.getResponseCode() or connection.getInputStream() or connection.getResponseMessage() or anything which is related to reponse from the server, the request will never be sent to server. Why do I need to do this? Or is there any way to write the data without getting the response? P.S. I have developed a server-side uploading servlet which accepts multipart/form-data and save it to files using FileUpload. It is stable and definitely working without any problem so this is not where my problem is generated. import java.io.Closeable; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.io.PrintWriter; import java.net.HttpURLConnection; import java.net.URL; import org.apache.commons.io.IOUtils; public class URLUploader { public static void closeQuietly(Closeable... objs) { for (Closeable closeable : objs) { IOUtils.closeQuietly(closeable); } } public static void main(String[] args) throws IOException { File textFile = new File("D:\\file.zip"); String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value. HttpURLConnection connection = (HttpURLConnection) new URL("http://localhost:8080/upslet/upload").openConnection(); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); OutputStream output = output = connection.getOutputStream(); PrintWriter writer = writer = new PrintWriter(output, true); // Send text file. writer.println("--" + boundary); writer.println("Content-Disposition: form-data; name=\"file1\"; filename=\"" + textFile.getName() + "\""); writer.println("Content-Type: application/octet-stream"); FileInputStream fin = new FileInputStream(textFile); writer.println(); IOUtils.copy(fin, output); writer.println(); // End of multipart/form-data. writer.println("--" + boundary + "--"); output.flush(); closeQuietly(fin, writer, output); // Above request will never be sent if .getInputStream() or .getResponseCode() or .getResponseMessage() does not get called. connection.getResponseCode(); } }

• Disable Autocommit in H2 with Hibernate/C3P0 ?

  - by HDave

  I have a JPA/Hibernate application and am trying to get it to run against H2 (as well as other databases). Currently I am using Atomikos for transaction and C3P0 for connection pooing. Despite my best efforts I am still seeing this in the log file (and DAO integration tests are failing): [20100613 23:06:34] DEBUG [main] SessionFactoryImpl.(242) | instantiating session factory with properties: .....edited for brevity.... hibernate.connection.autocommit=true, ....more stuff follows The connection URL to H2 has AUTOCOMMIT=OFF, but according to the H2 documentation: this will not work as expected when using a connection pool (the connection pool manager will re-enable autocommit when returning the connection to the pool, so autocommit will only be disabled the first time the connection is used So I figured (apparently correctly) that Hibernate is where I'll have to indicate I want autocommit off.

• C#.NET Socket Programming: Connecting to remote computers.

  - by Gio Borje

  I have a typical server in my end and a friend using a client to connect to my IP/Port and he consistently receives the exception: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond {MY_IP}:{MY_PORT}"—You don't need to know my IP. The client and server, however, work fine on the loopback address (127.0.0.1). I also do not have any firewall nor is windows firewall active. Server: static void Main(string[] args) { Console.Title = "Socket Server"; Console.WriteLine("Listening for messages..."); Socket serverSock = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPAddress serverIP = IPAddress.Any; IPEndPoint serverEP = new IPEndPoint(serverIP, 33367); SocketPermission perm = new SocketPermission(NetworkAccess.Accept, TransportType.Tcp, "98.112.235.18", 33367); serverSock.Bind(serverEP); serverSock.Listen(10); while (true) { Socket connection = serverSock.Accept(); Byte[] serverBuffer = new Byte[8]; String message = String.Empty; while (connection.Available > 0) { int bytes = connection.Receive( serverBuffer, serverBuffer.Length, 0); message += Encoding.UTF8.GetString( serverBuffer, 0, bytes); } Console.WriteLine(message); connection.Close(); } } Client: static void Main(string[] args) { // Design the client a bit Console.Title = "Socket Client"; Console.Write("Enter the IP of the server: "); IPAddress clientIP = IPAddress.Parse(Console.ReadLine()); String message = String.Empty; while (true) { Console.Write("Enter the message to send: "); // The messsage to send message = Console.ReadLine(); IPEndPoint clientEP = new IPEndPoint(clientIP, 33367); // Setup the socket Socket clientSock = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); // Attempt to establish a connection to the server Console.Write("Establishing connection to the server...

• How to Connect Crystal Reports to MySQL directly by C# code without DSN or a DataSet

  - by Yanko Hernández Alvarez

  How can I connect a Crystal Report (VS 2008 basic) to a MySQL DB without using a DSN or a preload DataSet using C#? I need install the program on several places, so I must change the connection parameters. I don't want to create a DSN on every place, nor do I want to preload a DataSet and pass it to the report engine. I use nhibernate to access the database, so to create and fill the additional DS would take twice the work and additional maintenance later. I think the best option would be to let the crystal reports engine to connect to MySQL server by itself using ODBC. I managed to create the connection in the report designer (VS2008) using the Database Expert, creating an ODBC(RDO) connection and entering this connection string "DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain" and in the "Next" page filling the "User ID", "Password" and "Database" parameters. I didn't fill the "Server" parameter. It worked. As a matter of fact, if you use the former connection string, it doesn't matter what you put on the "Server" parameter, it seems the parameter is unused. On the other hand, if you use "DRIVER={MySQL ODBC 5.1 Driver}" as a connection string and later fill the "Server" parameter with the FQDN of the server, the connection doesn't work. How can I do that by code? All the examples I've seen till now, use a DSN or the DataSet method. I saw the same question posted but for PostgreSQL and tried to adapt it to mysql, but so far, no success. The first method: Rp.Load(); Rp.DataSourceConnections[0].SetConnection("DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain", "database", "user", "pass"); Rp.ExportToDisk(ExportFormatType.PortableDocFormat, "report.pdf"); raise an CrystalDecisions.CrystalReports.Engine.LogOnException during ExportToDisk Message="Logon failed.\nDetails: IM002:[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.\rError in File temporal file path.rpt:\nUnable to connect: incorrect log on parameters. the InnerException is an System.Runtime.InteropServices.COMException with the same message and no InnerException The "no default driver specified" makes me wonder if the server parameter is unused here too (see above). In that case: How can I specify the connection string? I haven't tried the second method because it doesn't apply. Does anybody know the solution?
