  • SQL Server 2008 login problem with ASP.NET application: Failed to open the explicitly specified database

    - by eulerfx
    I am running SQL Server 2008 Express Edition on Windows Server 2008 with an ASP.NET application which must access the server. The ASP.NET application is associated with an application pool that runs on the NetworkService account. This account in turn has a Login and User record on SQL Server in the required database. When I attempt to run the ASP.NET website I get a blank page and when viewed in the error log, I seem to be getting this information event record: Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: myLocalMachine] The connection string has Trusted_Connection=True; and the required database specified. When I explicitly specify the user name and password I get another login error stating the password is incorrect, even though the same un/pw combination works through SQL Server Management studio. The NETWORK SERVICE account seems to have all the required privileges for the database. Also, I made a test ASP.NET website project which does a simple select from a table in that database, and using the same config file I am not getting the error and it seems to work. Is it something to do with trust levels then, because the original ASP.NET web app references various DLLs including open source libraries. Also, the application does not seem to be able to write to the event log itself, throwing a security exception, even though everything in the config files, including machine.config states the app is in full trust.

  • Task scheduled to wake laptop - only works when lid is open

    - by JD Pack
    I am running Windows 7 Starter on an Acer Aspire One laptop. I want my laptop to automatically run a task (backup the HDD to a network drive) once a week in the middle of the night. I scheduled the task in "Task Scheduler" and checked the box to wake the computer to run the task. I also changed the advanced power settings to allow wake timers. This was half of the solution. It now works flawlessly when the lid is open... the computer can wake itself up from either sleep or hibernate mode to perform the backup. When the lid is closed however, its sleeping beauty. Any ideas? I don't want to have to remember to open the lid once a week. It sort of defeats the purpose of an "automatic" backup. Update: I discovered that it can wake from sleep (or hybrid sleep), but not from hibernate when the lid is closed. This is good news. I'd still be curious about how to get it to work from hibernate, but I'm pretty happy about waking from sleep at least.

  • Open source alternative for Canonical Landscape?

    - by netvope
    From Canonical: Landscape is an easy-to-use systems management and monitoring service that enables you to manage multiple Ubuntu machines as easily as one through a simple Web-based interface. However, Landscape is not free. The RedHat counterpart Satellite has a free version called Spacewalk, but it doesn't work on Ubuntu. (There is an attempt to port Spacewalk to Debian, but it doesn't look like it's stable yet.) Are there any open source alternative to Landscape? Better yet, are there any Spacewalk-like software that works for both RedHat-based and Debian-based systems?

  • router w/ WOL out-of-the-box, or is known to work with open firmware

    - by Jaroslav Záruba
    I'm looking for a new WiFi router, and one key feature for me is WOL. Seems like many routers won't do this w/ factory firmware. Given my last router (Asus WL-520g) turned into a disco-brick couple hours after flashed to dd-wrt I'd prefer if the new one supported WOL out-of-the-box. other required features would be: dyndns service support port forwarding sometimes it is called "virtual server" I guess NAT loopback so I can access services running in my own network using dyndns hostname or public IP w/o getting too old (for example DIR-615 with factory firmware lets you wait literally minutes) did I mention WiFi? preferably w/ some range extending technology, if such stuff works at all

  • What ports do I need open for IMAP connections

    - by iamjonesy
    I'm developing a web application that connects to an IMAP mailbox and fetches emails as part of it's functionality. The application is PHP and I'm connecting like this: public function connect() { /* connect to gmail */ $hostname = '{imap.gmail.com:993/imap/ssl}INBOX'; $username = $this->username; $password = $this->password; /* try to connect */ $this->inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error()); } Developing locally on my mac this was fine, I was able to connect and get emails. However now that I've put the app on my web hosts server I'm getting the following error: Cannot connect to Gmail: Can't connect to gmail-imap.l.google.com,993: Connection timed out After checking with my hosting provider they told me outgoing connections on port 993 are blocked. Is there anyway around this? Otherwise I need to upgrade to a dedicated server :S

  • how to change the default open-with program to a program on the second disk

    - by Scott????
    I have a 250GB HDD for my system and a 60GB SSD using a SATA port. I installed most of my applications on the SSD. There's a strange thing though. I can not change the default open-with program to a program which is on the SSD. I think it may be caused by permission so I gave my user a 'full control' permission on the security tab in disk properties. But changing permissions is not work. After I choose an application (I've tried Notepad++, Sublime, 7Zip, etc.), nothing is added in the below window: Also, if I install 7Zip on my machine, the right click menu items can not be added.

  • Advice on coding Perl to work like PHP

    - by user272273
    I am first and foremost a perl coder, but like many, also code in PHP for client work, especially web apps. I am finding that I am duplicating a lot of my projects in the two languages, but using different paradigms (e.g. for handling cgi input and session data) or functions. What I would like to do is start to code my Perl in a way which is structured more like PHP, so that I a) am keeping one paradigm in my head b) can more quickly port over scripts from one to the other Specifically, I am asking if people could advise how you might do the following in perl? 1) Reproduce the functionality of $_SESSION, $_GET etc. e.g. by wrapping up the param() method of CGI.pm, a session library? 2) Templating library that is similar to PHP I am used to mixing my code and HTML in the PHP convention. e.g. i <h1>HTML Code here</h1> <? print "Hello World\b"; ?> Can anybody advise on which perl templating engine (and possibly configuration) will allow me to code similarly? 3) PHP function library Anybody know of a library for perl which reproduces a lot of the php inbuilt functions?

  • Moving delegate-related function to a different thread

    - by Chris
    Hello everybody. We are developing a library in C# that communicates with the serial port. We have a function that is given to a delegate. The problem is that we want it to be run in a different thread. We tried creating a new thread (called DatafromBot) but keep using it as follows (first line): comPort.DataReceived += new SerialDataReceivedEventHandler(comPort_DataReceived); DatafromBot = new Thread(comPort_DataReceived); DatafromBot.Start(); comPort_DataReceived is defined as: Thread DatafromBot; public void comPort_DataReceived(object sender, SerialDataReceivedEventArgs e) { ... } The following errors occur: Error 3 The best overloaded method match for 'System.Threading.Thread.Thread(System.Threading.ThreadStart)' has some invalid arguments C:...\IR52cLow\CommunicationManager.cs 180 27 IR52cLow Error 4 Argument '1': cannot convert from 'method group' to 'System.Threading.ThreadStart' C:...\IR52cLow\CommunicationManager.cs 180 38 IR52cLow Any ideas of how we should convert this to get it to compile? Please note that comPort.DataReceived (pay attention to "." instead of "_") lies within a system library and cannot be modified. Thanks for your time! Chris

  • Listing serial (COM) ports on Windows?

    - by Eli Bendersky
    Hello, I'm looking for a robust way to list the available serial (COM) ports on a Windows machine. There's this post about using WMI, but I would like something less .NET specific - I want to get the list of ports in a Python or a C++ program, without .NET. I currently know of two other approaches: Reading the information in the HARDWARE\\DEVICEMAP\\SERIALCOMM registry key. This looks like a great option, but is it robust? I can't find a guarantee online or in MSDN that this registry cell indeed always holds the full list of available ports. Tryint to call CreateFile on COMN with N a number from 1 to something. This isn't good enough, because some COM ports aren't named COMN. For example, some virtual COM ports created are named CSNA0, CSNB0, and so on, so I wouldn't rely on this method. Any other methods/ideas/experience to share? Edit: by the way, here's a simple Python implementation of reading the port names from registry: import _winreg as winreg import itertools def enumerate_serial_ports(): """ Uses the Win32 registry to return a iterator of serial (COM) ports existing on this computer. """ path = 'HARDWARE\\DEVICEMAP\\SERIALCOMM' try: key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, path) except WindowsError: raise IterationError for i in itertools.count(): try: val = winreg.EnumValue(key, i) yield (str(val[1]), str(val[0])) except EnvironmentError: break

  • WinCE and PC USB communication

    - by sebeksd
    We are developing some device and we need to find good solution for one of needed functionality. Thing is that we need communicate WinCE 6.0 (ARM) and Windows on PC. Easiest way is of course COM port but in our case it is impossible (all serial ports are used on WinCE and we don't want to add one more). Second option is LAN but for us it is not the best option for few reasons. So there is third option we could use. USB to USB communication but how to do that ? Of course WinCE is USB Device and PC is USB Host so all hardware basics are meet. We could use Active sync but there are few problems with it: - WinCE 6.0 is not working with WMDC (drivers on device just crash after connecting device with PC) and I didn't find any solution for it so in this case we need to use WinXP on PC side (old ActiveSync) - we need to filter communication with active sync to only our application, no other non authorized software should be allowed (what I know this is imposible to obtain). So propably best way to do what we need is to communicate throug USB like standard COM (serial communication). The question is, how it could be made, are we need to write driver on WinCE and also a Driver on Windows (PC), or there are better solution? Maybe some driver for WinCE 6.0 that would emulate Virtual COM on PC side (and of course allow standard Read/Write to it on WinCE side) ? Could someone tell me if something like that exists ?

  • Fake serial communication under Linux

    - by kigurai
    I have an application where I want to simulate the connection between a device and a "modem". The device will be connected to a serial port and will talk to the software modem through that. For testing purposes I want to be able to use a mock software device to test send and receive data. Example Python code device = Device() modem = Modem() device.connect(modem) device.write("Hello") modem_reply = device.read() Now, in my final app I will just pass /dev/ttyS1 or COM1 or whatever for the application to use. But how can I do this in software? I am running Linux and application is written in Python. I have tried making a FIFO (mkfifo ~/my_fifo) and that does work, but then I'll need one FIFO for writing and one for reading. What I want is to open ~/my_fake_serial_port and read and write to that. I have also lpayed with the ptymodule, but can't get that to work either. I can get a master and slave file descriptor from pty.openpty() but trying to read or write to them only causes IOError Bad File Descriptor error message.

  • What are some viable alternatives to BizTalk Server?

    - by Kilhoffer
    In evaluating different systems integration strategies, I've come across some words of encouragement, but also some words of frustration over BizTalk Server. What are some pros and cons to using BizTalk Server (both from a developer standpoint and a business user), and should companies also consider open source alternatives? What viable alternatives are out there? EDIT: Jitterbit seems like an interesting choice. Open Source and seems to be nicely engineered. Anyone on here have any experience working with it?

    Can we get a list of free and open source projects, which can be supported through purchasing branded garment? Free Software Foundation http://shop.fsf.org/ ps. I know this is extremly off-topic. But I'd like to buy clothing and support open source at the same time, if possible. And I'd like to know, where this is possible.

  • Is It Possible to Make Close Sourced PHP Product?

    - by Morgan Cheng
    I'm curious that whether all PHP product must be open sourced if it is to be deployed to other's web site. Since PHP code is executed by interpretation, if I have PHP product to be deployed on other's host, it seems no reason to prevent others view the source code. So, PHP product is destined to be open source, right?

  • Are there any inherent benefits or drawbacks to choosing Google Code vs. SourceForge vs. Codeplex?

    - by kdmurray
    I've got a couple of different projects that I'd like to post up as open source. I've been trying to decide which of the three big open-source project hosting sites makes the most sense, or if I should just host it myself. Are there any inherent drawbacks or benefits to these three? Is there a "best" place to host a project? Do different sites make more sense for different kinds of projects?
