  • WPF DataGrid: How to get Converter

    - by Nike
    I create DataGrid Columns with Binding (where i is a Int value): dataGrid.Columns.Add(new DataGridTextColumn { Header = i.ToString(), Binding = CreateBinding(i), }); private Binding CreateBinding(int num) { Binding bind = new Binding(string.Format("[{0}]", num)); bind.Converter = new CellValueConverter(); return bind; } In the CreateBinding method I have an access to bind.Converter property. I need to call Converter.Convert() method in some handler, but there is no Converter property when I try to access it: (dataGrid.Columns[clm] as DataGridTextColumn).Binding."no Converter property!" How can I get my CellValueConverter which was created for particular Column?

  • MikroTik ipv6 Tunnel

    - by MikeSmitty
    I've got a MikroTik router set up with the latest stable OS on it, and I just set up an ipv6 tunnel with Hurricane Electric, but I'm having an odd issue with it. I can't ping anything until I first ping the tunnel endpoint on HE's side. After that I can ping any ipv6 address fine, but give it a little time (say, maybe 30 sec) and I can't ping any ipv6 addresses again. Whenever it stops allowing ping to go through I notice the counter on my firewall rule that drops invalid connections goes up. this is my ipv6 firewall config: add action=accept chain=input comment="" connection-state=established \ disabled=no in-interface=sit1 add action=accept chain=input comment="" connection-state=related disabled=no \ in-interface=sit1 add action=accept chain=input comment="" disabled=no in-interface=bridge \ src-address=ipv6_address_here/64 add action=drop chain=input comment="" connection-state=invalid disabled=no \ in-interface=sit1 add action=drop chain=input comment="" disabled=no in-interface=sit1 Any ideas on what it could be?

  • Duplicate incoming TCP traffic on Debian Squeeze

    - by Erwan Queffélec
    I have to test a homebrew server that accepts a lot of incoming TCP traffic on a single port. The protocol is homebrew as well. For testing purposes, I'd like to send this traffic both : - to the production server (say, listening on port 12345) - to the test server (say, listening on port 23456) My clients apps are "dumb" : they never read data back, and the server never replies anyway, my server only accepts connections, and do statistical computations and store/forward/service both raw and computed data. Actually, client apps and hardware are so simple there is no way I can tell clients to send their stream on both servers... And using "fake" clients is not good enough. What could be the simplest solution ? I can of course write an intermediary app that just copy incoming data and send it back to the testing server, pretending to be the client. I have a single server running Squeeze and have total control over it. Thanks in advance for your replies.

  • Virtualmin Configuration

    - by Allen
    I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

  • iptables: How to read this OPT string?

    - by alex
    I have a simple INPUT rule for iptables that logs any new connections to a logfile. --log-tcp-options and --log-ip-options flags are both set and I get the appropriate OPT output. One line of my log looks something like this: Nov 29 17:00:00 IN=venet0 OUT= MAC= SRC=x.x.x.x DST=x.x.x.x LEN=64 TOS=0x00 PREC=0x00 TTL=53 ID=37898 DF PROTO=TCP SPT=57755 DPT=8888 WINDOW=65535 RES=0x00 SYN URGP=0 OPT (0204057D010303010101080A3E521D4D0000000004020000) I would like to understand how to interpret the OPT string (bold). Is there some documentation available on what it actually means? How could I make it human-readable?

  • Enable: Asp.net connection pool monitoring with performance monitor

    - by BlackHawkDesign
    If this question is at the wrong forum, be free to tell me. I'm a c# developer, but I'm running in a system management issue here. Intro: Im suspecting that an asp.net application is having some issues with the connection pool and that the pool is flooding from time to time. So to make sure, I want to monitor the connection pool. After some searching I found this article : http://blog.idera.com/sql-server/performance-and-monitoring/ensure-proper-sql-server-connection-pooling-2/ Basicly it explains stuff about connection pools and how you can monitor the application pool with performance monitor. The problem: So I logged in to the asp.net server(The sql database is hosted on a different server) which hosts the website. Started performance monitor. But when I want to select 'Current # pooled and nonpooled connections', I have no instance to select. There fore I can't add it. Question How can I create/supply an instance so I can monitor the connection pool? Thanks in advance BHD

  • Connection to SQL Server 2008 R2 Database Server is SLOW

    - by AbeP
    The database server is a VM running SQL Server 2008 R2 on top of Windows Server 2012, 24GB RAM allocated and 2TB of disk space. Overall, the database connections are very slow and one thing that stands out is that the connection to the database server via SSMS takes 5-10 seconds. On other much less powerful servers, it takes 1-2 seconds. The VM is technically way more powerful than other machines, but the connection to the server is too slow. So, my guess is the issue is network related, but any clues on where I should be looking? Thanks!

  • MOSS 2007 authentication

    - by Dante
    Hi, I have a MOSS web site configured with Windows Integrated Authentication. I added a couple of local users in the server, added them to Sharepoint groups, and I can log into my site (as long as the local user is part of the administrators group... odd). If I add a domain user to the Owners group, I can't access the site with it. Anybody knows what must be done to open access to domain users in a site configured with Windows Authentication or Basic Authentication? Thanks in advance

  • How do I set up one time password authentication?

    - by scraimer
    I have a home network which I access remotely quite a bit. But I'm worried about security. While I do have strong passwords, I'm worried that someone will acquire my password and use it to gain access. I heard about "one time passwords" and even got to use them at my university. We'd just press a button on a device (or run an application on a phone) and get a generated password that would work for the next minute or so. How can I set something like that up? Are there systems that are easy to use and set up? Has anyone played around with an SDK of one of these systems? Where can I get a starter kit from? EDIT: I'm running a mixed Linux and Windows network, and I'm vaguely hoping to use this for authenticating on both operating systems. (No, there's no domain controller, but I can set one up using Samba, I suppose.)

  • Accelerometer API for Laptops

    - by FreshCode
    Most IBM (and some Dell) laptops have built-in accelerometers to stop any moving parts during a sudden fall, but I was unable to find a standardised Windows API to access this data. I assume that each manufacturer would provide a driver to interface with the sensor. Which popular laptop brands come standard with accelerometers accessible from an API and which libraries should I use to access the data? Does an API* exist to abstract away the differences between different manufacturers? I am aware of the Windows 7 Sensor API, but I would like support for XP and earlier.

  • Best Practices Question on using an ObjectDataSource in asp.net

    - by Lill Lansey
    Asp.net, c#, vs2008, sqlserver 2005. I am filling a DataTable in the data access layer with data from a sqlserver stored procedure. Best Practices Question – Is it ok to pass the DataTable to the business layer and use the DataTable from the business layer for an ObjectDataSource in the presentation layer, or Should I transfer the data in the data table into a List and use the List for an ObjectDataSource in the presentation layer? If I should transfer the data to a List, should that be done in the data access layer or the business layer? Does it make a difference if the data needs to be edited before being displayed?

  • Reset Network Load Balancer Connection Pool

    - by bill_the_loser
    I am currently working on load testing a web application on a virtual machine cluster. I am looking for a way to flush the connection pool / NLB cache so that it is like each machine connecting to the NLB is connecting for the first time and doesn't get directed back to the node that it was on last time. This a Windows 2003 Server cluster, behind a Microsoft software based Network Load Balancer. Additional Information: To do the load testing I'm using virtual machines, one for each node on the cluster. Somehow I got two virtual machines connecting to the same node and I'm looking for an easier way to reset those connections without going in to the NLB Manager and stopping and starting each node on the NLB. Update: We went ahead and changed the affinity on all of the nodes of the cluster to none. Now it's a non-issue.

  • ctypes and pointer manipulation

    - by Chris
    I am dealing with image buffers, and I want to be able to access data a few lines into my image for analysis with a c library. I have created my 8-bit pixel buffer in Python using create_string_buffer. Is there a way to get a pointer to a location within that buffer without re-creating a new buffer? My goal is to analyze and change data within that buffer in chunks, without having to do a lot of buffer creation and data copying. In this case, ultimately, the C library is doing all the manipulation of the buffer, so I don't actually have to change values within the buffer using Python. I just need to give my C function access to data within the buffer.

  • ServerAlias www.example.com is not recognized

    - by Tianzhou Chen
    Below is my config file: NameVirtualHost 12.34.56.78:80 < VirtualHost 12.34.56.78:80 ServerAdmin [email protected] ServerName domain1.com ServerAlias www.domain1.com DocumentRoot /srv/www/domain1.com/public_html1/ ErrorLog /srv/www/domain1.com/logs/error.log CustomLog /srv/www/domain1.com/logs/access.log combined < /VirtualHost < VirtualHost 12.34.56.78:80 ServerAdmin [email protected] ServerName domain2.com ServerAlias www.domain2.com DocumentRoot /srv/www/domain2.com/public_html1/ ErrorLog /srv/www/domain2.com/logs/error.log CustomLog /srv/www/domain2.com/logs/access.log combined < /VirtualHost The thing is when I put www.domain1.com into browser, apache2 doesn't retrieve the web page resides in /srv/www/domain1.com/public_html1/, instead, it gets the page from the default document root defined in another file. However, if I put www.domain2.com, everything works fine. I don't see any difference between two VirtualHost config block, so I wonder what does make the difference. BTW, I haven't put any .htaccess file under their document root. Thanks for your advice! Tianzhou

  • Windows 2012 Server Hyper-V: Cannot see LAN

    I have one NIC on the machine loaded XP on the Hyper-V and had chosen the network as virtual switch. No LAN and no internet shows up on the client. Am I missing something? it used to work in 2008-R2. Details: One network card on machine (Qualcomm Atheros AR8131 PIC-E Gigabit Ethernet controller) The virtual machine hard disk is pointing to and existing XP-SP2 hard disk created using VPC 2007 The Virtual machine Network Adapter is setup as Virtual Switch to the real ethernet controller with Enable virtual LAN identification set to 2 (no other virtual machine is created in the system) After the virtual machine boots LAN shows empty in Control Panel Network Connections (this is XP client) and I also cannot access the internet. XP is showing activation prompt but as far as I know it should not disable the network! Virtual network switch is set to External

  • Using a REST API and iPhone/Objective-C

    - by Neil Desai
    So I'm brand new to Netflix's API and have never used an API ever before. I'm ok with Objective-C and Cocoa Touch but just have no clue where to start when accessing the API and how to in general. Can someone help me get started with some code that will access titles in Netflix or just how to access a REST API in general with authentication. Thanks. Update: I've looked at the documents and I'm still a little lost because the Netflix API is a little weird with OAuth. Any help?

  • Add power over Ethernet without new switches?

    - by dannymcc
    I need to power 16 IP phones over their Ethernet connections. I am in the process of changing our switches and only the phones need PoE, everything else is powered by mains cables. I have contacted the supplier of the phones and for 16 mains leads it will be close to £300. I know it's possible to get a PoE injector that goes between the mains and the phone but I would like to do this as tidily as possible and ideally in bulk. I imagine something that looks like a switch but doesn't actually 'switch' if that makes sense. Basically I want to inject power to 16 devices at once.

  • Windows 7 recognises the wrong router.

    - by Henry
    I have a cable router connected to my cable ISP. On the LANs are 4 computers, one of which is a dual boot XP/Win7 machine. I was given an ADSL wireless router which I connected to one of the LAN sockets on my cable router. I don't have an ADSL connection. All the machines connect correctly, some wirelessly, when my dual boot machine is in XP or off. However, when I go into Win 7 on that machine it finds the ADSL router and wants to connect through that (there's no ADSL connection) instead of my cable router and modem. I've turned DHCP off on the ADSL modem and even tried bridging its connections but neither of these have any effect. To get 7 connected, I have to either disconnect the ADSL router, or switch it off. Remember, the SAME computer on the same LAN works perfectly with the same router connected in XP! How then, can I get Win 7 to recognise the correct router?

  • Double GPRS/EDGE speed with two mobile phones at once?

    - by Patrick
    Hi, I'm using my mobile phone to connect to the internet in an area where only GPRS/EDGE is available. To increase the connection speed I would like to use a technique called connection teaming. E.g. I would use two mobile phones / usb sticks to go online with different providers at the same time and let the software distribute requests over both connections. My questions are: is there a software available to do connection teaming? It sounds like Midpoint was able to do it but it's over 7 years old and is unlikely to run on Windows 7 has anybody tried this? Thanks a lot, Patrick

  • Git under windows: MSYS or Cygwin?

    - by Joce
    I plan to migrate my projects over to git, and I'm currently wondering which is the best and / or most stable option under windows. From what I gather I basically have 2.5 options: MSYSgit git under Cygwin (aka 2.5) MSYSgit from a Cygwin prompt (given that Cygwin git is already installed). Note: IMO Cygwin in itself is a big plus as you can have access to pretty much all the *nix command line tools, as where with MSYSgit bash, you only have access to a rather small subset of these tools. Given that, what option would you suggest?
