  • How to raise an event when another event is raised?

    - by WulfgarPro
    Hi, I have an application that handles the OnQuit event of another running application. I would like to raise an additional (custom) event when the OnQuit event is handled. How could I implement such an event? My OnQuit handler is like so: private void StkQuit() { _stkApplicationUi.OnQuit -= StkQuit; Marshal.FinalReleaseComObject(_stkApplicationUi); Application.Exit(); } The reason I require the additional event is so that I can tell my View layer that the application has exited. If this is not the correct way, what would be better? WulfgarPro

  • Handling multiple post-defined datasource connections based on user

    - by choudeshell
    How should I handle multiple user-connection defined datasource connection in my .NET application? To illustrate this better; the user provides three (3) pieces of information, username, password and data source name. This data source name is then looked-up in a central database telling that application which main database this user should connect to. My question is, in the DataAccess layer, should we only pass down enough information to uniquely identify that user, and query the central database each time in the DAL; or, should we provide another way to pass the datasource connection down to the DAL?

  • How should I mock out my data connectivity

    - by BobTheBuilder
    I'm trying to unit test my Data Access Layer and I'm in the process of trying to mock my data connectivity to unit test my DAL and I'm coming unstuck trying to mock out the creation of the commands. I thought about using a queue of IDbParameters for the creation of the parameters, but the unit tests then require that the parameters are configured in the right order. I'm using MOQ and having looked around for some documentation to walk me through this, I'm finding lots of recommendation not to do this, but to write a wrapper for the connection, but it's my contention that my DAL is supposed to be the wrapper for my database and I don't feel I should be writing wrappers... if I do, how do I unit test the connectivity to the database for my wrapper? By writing another wrapper? It seems like it's turtles all the way down. So does anyone have any recommendations or tutorials regarding this particular area of unit testing/mocking?

  • Outputting audio stream into microphone

    - by Brap
    Hey everyone. Is there a way of outputting audio from my program and redirecting that stream to the system's microphone input 'layer'? I understand this might require some low-level calls being 'Pinvoked', but are there any articles that might help me. For example, if I was to run the output audio stream of my application into Window's Sound Recorder program, it would think that the audio is coming from a microphone and thus record that. I don't want to record a stream, just output it to the device's micrphone input. Thanks for any ideas.

  • Django Project Done and Working. Now What?

    - by Rodrogo
    Hi, I just finished what I would call a small django project and pretty soon it's going live. It's only 6 models but a fairly complex view layer and a lot of records saving and retrieving. Of course, forgetting the obvious huge amount of bugs that will, probably, fill my inbox to the top, what would it be the next step towards a website with best performance. What could be tweaked? I'm using jmeter a lot recently and feel confident that I have a good baseline for future performance comparisons, but the thing is: I'm not sure what is the best start, since I'm a greedy bastard that wants to work the least possible and gather the best results. For instance, should I try an approach towards infrastructure, like a distributed database, or should I go with the code itself and in that case, is there something that specifically results in better performance? In your experience, whats pays off more? Personal anecdotes are welcome, but some fact based opinions are even more. :) Thanks very much.

  • Hibernate HQL to basic SQL (no joins)

    - by CC
    Hello everybody, I working on a project with Hibernate and we need to replace Hibernate with some "home made persistence" stuff. The idea is that the project is big enough, and we have many HQL queries. The problem is with the queries like select a,b from table1, table2 on t1.table1=t2.table2 Basically all joins are not supported by our "hand made persistence" stuff. What I would need, is to be able to do some sort of transcoder, which will take as a input the HQL queries and output some SQL, but SQL without joins I hope you get the idea. My persistence layer does not supports joins. Does anybody has any idea about something like that? Some framework, or something? Thanks alot everybody. C.C.

  • Should my DAOs (Database Entities) Directly match my UI Objects?

    - by scarpacci
    I am trying to figure out best practice for N-Tier application design. When designing the objects my UI needs and those that will be persisted in the DB some of my colleagues are suggesting that the objects be one in the same. This doesn't not feel right to me and I am ultimately looking for some best practice documentation to help me in this decision. I honestly do not understand why I would want to design this way given that other applications may want to interact with my Data Access Layer....or it is just ignorance or lack of understanding on my part. Any documentation, information you could provide would be greatly appreciated. Just want to better understand these concepts and I am having a hard time finding some good information on the best practice for implementing these patterns (Or it is right in front of me on what I found and I didn't understand what was being outlined). Thanks, S

  • How to assure applying order of function decorators in Python?

    - by Satoru.Logic
    Some decorators should only be used in the outermost layer. A decorator that augments the original function and add a configure parameter is one example. from functools import wraps def special_case(f): @wraps(f) def _(a, b, config_x=False): if config_x: print "Special case here" return return f(a, b) How can I avoid decorators like this getting decorated by another decorator? EDIT It is really disgusting to let everyone trying to apply a new decorator worry about the application order. So, is it possible to avoid this kind of situation? Is it possible to add a config option without introducing a new parameter?

  • 2 Spaces or 1 Tab, what's the standard for indentation in the Rails Community?

    - by viatropos
    I've noticed that most of the HTML/XML/HAML that gets generated from plugins uses 2 spaces instead of 1 tab. I use textmate and have tabs set to 4 spaces for HAML/HTML/XML and 2 spaces for Javascript/Ruby, but I only have to press the tab key once to get nice indentation. Pressing the space bar twice and delete twice seems like too much work :p. Do you manually type two spaces, or is some middle layer converting tabs to two spaces? Or do just a few of you use tabs?

  • As2 loading swf instance

    - by user1748474
    I have a .swf which loads an external .swf: this.createEmptyMovieClip("container_mc", this.getNextHighestDepth()); var my_listener:Object = new Object(); my_listener.onLoadComplete = function(target_mc:MovieClip) { target_mc._x = 50; target_mc._y = 50; addChild(my_loader); var blocker = my_loader.content.test blocker._visible = false; } my_listener.onLoadProgress = function(target_mc:MovieClip) { trace(target_mc.getBytesLoaded() + " out of " + target_mc.getBytesTotal()); } var my_loader:MovieClipLoader = new MovieClipLoader(); my_loader.addListener(my_listener); my_loader.loadClip("child_as2.swf", container_mc); I want to acces the external swf and make the movieclip with instance name test visible = false; but it won't work. I have tried a lot of codes and right now it throws me this error: Scene=Escena 1, layer=Capa 1, frame=1, Line 9 There is no property with the name 'content'. Any idea? If you have a better code i will thank you so much.

  • Continual "The Windows Filtering Platform has blocked a connection" errors?

    - by Richard
    Our systems have been compromised by something recently which has lead us to carry out a more detailed look at what is happening on our workstations. I have noticed an issue where the Security log of this Windows 7 workstation is continually logging a security "Audit Failure" where the detail is that "The Windows Filtering Platform has blocked a connection". This is happening thousands of times a day and would appear to be our BT Business Broadband HGV 2700 ADSL router attempting to connect to Port 137 (NET Bios) on my workstation and being blocked. This has unfortunately had the effect of filling up the log files so much that anything which might have been of use which was logged over the weekend to help debug the intrusion has been "overwritten off the end" of the Security log. (I've since increased the log file size limits massively and turned on archiving). Does anyone know if this is standard behaviour of a BT ADSL router or whether this indicates that the router is compromised in some way or malfunctioning, or have any further suggestions as to how to diagnose this problem?

  • Unable to make admin interface connection to server when moving a mailbox.

    - by TheCodeMonk
    I have an existing Exchange 2003 server running on Windows Server 2003. I am in the process of replacing our current server infrastructure and virtualizing it all in Hyper-V. I have Essential Business Server 2008 installed in 3 separate VMs and running. Everything seems to be working fine so far. I am now trying to migrate my exchange mailboxes over to the new exchange server in the messaging server and every time I try I get this error: MapiExceptionNetworkError: Unable to make admin interface connection to server. (hr=0x80040115, ec=-2147221227) I have done some searching and found solutions like adding the computer to the exchange domain servers groups and install group, also making sure the user logged into the new server is in the proper groups. I also saw a solution in making sure that any unused NICs are disabled. I've tried all that to no avail.

  • Watchguard config, drop-in or mixed-routing mode?

    - by vfilby
    I have a Watchguard XTM 2 that is currently acting as a firewall and a router for my business network, I currently have the WG setup in mixed-routing mode and am happy with the current configuration. The reason I am curious about drop-in mode is because I would like to use all the interfaces on the back of the watchguard for the same subnet. My understanding is that drop-in mode will put them all on the same subnet, but it is unclear from the manual that the routing/firewall/vpn will still work as expected. This WG is right behind a DSL modem that is setup in bridge mode, so the WG is handling all PPPoE auth and routing for the network.

  • Sending emails from PHP - email providers vs GAE

    - by nrph
    I need to send emails from my social service (this is continuation of Experiences in mailing to registered users). I got strong feeling that it's better to avoid problems with email server configuration and maintance and to choose email provider which will take care of all painful problems. So several offers were compared: http://imgur.com/JkK2X.jpg Three of them look very attractive: Postageapp / Sendgrid / CritSend As alternative i'm considering setup GAE app. Email provider is quite easy to start work with, but have no idea how much effort require GAE to integrate with PHP. So my question is: which option is better to choose: email provider GAE ? Two factors are important here: business background (therefore prices are mentioned), work required to setup and maintain desired solution. Preferably i would love to avoid all email-related problems (like black lists and so on).

  • Migrate SBS 2008 with Exchange 2007 to new hardware

    - by MikeT505
    Hello, We have run out of hard disk space on our existing Small Business Server 2008 and simply wish to upgrade both of the hard drives (currently raid 1) - without too much hassle. My main concern is how to copy across the embedded version of Microsoft Exchange 2007. Is there a simple way to copy all the data across and upgrade? Or is it best to backup and do a clean install? - The difficulty is that it's the same server, so we can't replicate mailboxes for exchange. Any hints or tips welcomed!?

  • Windows update doesn't list update details, only the number of updates

    - by leodip
    Hi all, My system is Vista Business 32 bits SP2. When I click "Windows update", I can see there are 2 available optional updates. If I click the link "2 optional updates are available" to see what the updates are, I get: http://leodip.s3.amazonaws.com/windows%5Fupdate2.PNG The details about the updates are EMPTY. Any idea why this is happening? It doesn't happen only with optional updates, but with critical updates as well. I would like to fix this, so I can see what the updates are. Thanks!

  • Make windows 7 client compatible with windows 2003 server

    - by caspert
    Hi, I am sysadmin for a small business with 30 clients. We have a server running windows 2003 and all the client-computers run windows XP. Now this is not an important issue, but it would be nice if it worked. My personal (home) computer is running windows 7 RC. When I bring my home-computer to work and log into the network with domain\username it logs me in just fine. Although, approving my profile, letting me into the network, including all network drives and printers, it does not download the profile fully. I do believe it might be getting the roaming profiles. So all my user- items, documents etc. attached to the profile does not show up on Windows 7. Is there any way to make it fully download the profile? as it does with Windows XP.

  • Assistance in setting up new APC Smart-UPS RT on a new VMware enviroment

    - by user38085
    I'm new to the realm of setting up a APC Smart-UPS RT 8000VA UPS with a management network card (AP9618). The project calls for the upgrade of the firmware for the network card to the newest and greatest. It also calls for the Powerchute Business Software to be installed with notifications setup per email for temperature, shutdown, and battery low. I know I'll have to use the serial cable to flash the firmware and install the software on one server 2003 box. Also on that server I'll have to install the software and setup the GUI (IP address) interface. Whats confusing the most is the whole process, and steps to use without taking down the network, which would be very bad. In flashing the firmware does it take down the UPS? Do i have to run BOOTP commands to setup the network card? Also no agents will be used on any of the VWware OS's and no SNMP trap will be used.

  • DD-WRT Router acting as a Switch and Wi-Fi AP

    - by dotnetchris
    Recently I upgraded to Comcast Business and their modem has a built-in router so I took off my DD-WRT router and moved to a location in my home where I needed more ports and Wi-Fi (preferably without running new Ethernet cables since it's 50-100 foot run through floor and ceilings). I have my network cable from my Comcast modem going into Port 1 of my DD-WRT router with Port 2 and 3 being networked PCs. I have DD-WRT setup as a DHCP forwarder with the firewall disabled. This lets my all of my devices access the network fine. Is the correct the way to do this? Or is this a less optimal solution and it should be done in a slightly different way?

  • Determine which active directory object is referred to by GUID in a Directory Synchronization Error Report

    - by Michael Shimmins
    We have active directory syncronization setup between our on-premises AD server and Microsoft hosted Exchange (business productivity online services). I've started getting a daily error report, which details an error for a specific AD user, however it references it by GUID. I can't find any info on how to translate that object guid into something meaningful so I can find and fix the problem. The error is reported as: Error 005: Unable to set the alias for this object in Microsoft Online Services because either the primary SMTP address, the e-mail nickname, or the SAM account name in the local Active Directory contains an invalid character. in reference to the Object GUID: CN={8443cbb4-5199-49f0-9529-ce965430dca6} How can I translate that object guid into a friendly object name?

  • Changing default gateway on workstations connected to Windows Domain SBS server

    - by Gary B2312321321
    We have xp workstations connected onto a small business server acting as active directory/isa firewall/proxy (no dhcp). Is there a reason that after installing a 2nd firewall on the network (same subnet etc), that changing the default gateway on the workstations isnt sufficient to route inet traffic through the new firewall? A freshly setup linux box connects straight on to the alternate firewall with just ip, default gateway. dns settings. Will having ISA still active on the network confuse the process? Are there further config settings deeper down in windows that need attention? Any ideas pointers on this would be appreciated? Other info: Firewalls tried: Smoothwall and Ipcop; small ethernet netwoork 40 pcs; can ping to new firwalls from workstations; activating web proxy on new firewall and reconfiguring workstation browser works fine; Point of 2nd firewall is lack of some necessary features on ISA for a linux app; Would be nice to have some redundancy to though

  • How can I connect any USB device to my computer wirelessly?

    - by daviesgeek
    I am trying to connect the Canon 550D wirelessly to my computer so that I can control it from at a distance. It can connect normally via a USB cable, so I was wondering if there was a way to plug a dongle into the computer, and a dongle into the camera so the two can connect. I'm basically looking for a really long USB cord that will work over long distances (200+ feet). Another important factor is that I really would prefer not having use a power cord, rather just plugging in a dongle, as it will make the setup more mobile. Does anything like this exist? (I know that Cables Unlimited had something like what I wanted, but they went out of business last year)

  • Windows SBS 2003 DNS taking over network

    - by Simon
    I have Windows Small Business Server 2003 premium edition on my new server box, this hosts a webapp on IIS. It has set up a DNS Server to solve requests to the webapp. I have a linux server/router that has does DNAT and portforwards port 80 to the new box. My linux router serves as a firewall and dhcp When i plug the SBS2003 server to the network, it leaves everyone on my network without web browsing, it looks like the DNS requests are going to the new server. I configured the DNS forwarders on SBS2003 to my ISP dns but it doesnt work... Is there something i am missing?

  • Good low-cost SSL certificate providers

    - by phenry
    We need an SSL certificate to facilitate remote access and administration by a small number of employees. I don't want to have to train a bunch of non-technical users to install a self-published cert on their home computers, so I'd prefer to purchase one from a well-trusted provider. We won't be using it for any kind of e-commerce or things like that, so it seems hard to justify paying the prices demanded by some of the big-name providers. Who are some good low-cost providers to consider? What are the important differences between the offerings that are available at different price points? (And is the certificate business really as much of a racket as it seems?)

  • How to cluster two IIS servers for failover?

    - by Ram Gopal
    We have IIS servers running in 2 machines hosting few webservices which provided some integration services to an old document Mgmt system, word/excel related service, etc.... We need to cluster/load balance these 2 IIS in order to achieve a fail-over. i.e If one of the IIS server is down, the other on should be able to handle the request. The reverse proxy used in the DMZ is also IIS 7.5 Our overall business application is in fact a J2EE one and we have successfully deployed on a weblogic cluster installed on the same two machines and load balance from the same above mentioned IIS reverse proxy at DMZ. But we do not know how to achieve this in case of IIS.
