  • Delphi - Sharing violation opening text file

    - by Simes
    I'm trying to open a text file for reading in a Delphi 7 app, but am getting I/O error 32 (sharing violation) because another application already has the file open. I've tried setting FileMode to "fmOpenRead or fmShareDenyNone" but now realise this doesn't apply to text files anyway. Is there a way of reading text files that are open by another application? var f: TextFile; begin FileMode := fmOpenRead or fmShareDenyNone; // FileMode IS NOT APPLICABLE TO TEXT FILES!! AssignFile(f, FileName); Reset(f);

  • Sharing session (or cookie) using Grails acegi plugin

    - by firnnauriel
    Is it possible for two different Grails project, also having different domains, to share a session/cookie? Let's say I have 2 sites: www.mycompany.com, and, www.othercompany.com. Assume that both sites are having same domains, and same database and records too. What I want to know is if this code: authenticateService.userDomain() or even the authenticateService.isLoggedIn() will behave and return exactly the same object/result whether it is called in either of the site. Basically, what we need is a solution for sharing/identifying logged in user between two different sites. Need more details on how to implement this using acegi 0.5.2 and grails 1.2.1. Hoping for any leads on this. Thank you.

  • Instant file sharing between users in PHP

    - by Skyfe
    Hi there, Working on a rather complex system in which users can directly exchange files with eachother from the website. However is any of these things possible: EITHER * Have another user download a file which is still being uploaded by another user ( in progress ) OR * Make a user automaticly ( instant ) download a file from another users PC through our website OR * Make a user automaticly (instant) download a file from our server ( so it's directly downloaded to the users pc and the progress shown on our website of the download progress, without the normal internet explorer dialog downloading the file or firefox ). Thank you very much in advanced, Best Regards, Webcodez.net. UPDATE: an example would be MSN's file sharing but then through a website instead of application.

  • Sharing state/changes across ViewModels

    - by joshperry
    I have an App which has a Tasks tab and a Projects tab. I decided to make a separate ViewModel for each of the tabs, TasksViewModel and ProjectsViewModel. The Tasks tab has a new task area with an associated project pulldown and the Projects tab (obviously) has a list of projects. What I'd like is for the pulldown on the Tasks tab to share the same collection as the Projects tab list so that any time I add or remove a project on the Projects tab the list on the Tasks tab is up to date automatically. This worked well with a single ViewModel but it was beginning to become quite unruly. Should I not have split into two ViewModels? Is there a common method of sharing data like this? Perhaps pass the same ObservableCollection<Project> into each of the ViewModels? Perhaps some type of notification back to the TasksViewModel along the lines of ICollectionChanged. Appreciate any insight/input!

  • Delete file after sharing via intent.

    - by Matt
    I'm trying to delete a temporary file after sharing it via android's Intent.ACTION_SEND feature. Right now I am starting the activity for a result and in OnActivityResult, I am deleting the file. Unfortunately this only works if I am debugging it with a breakpoint, but when I let it run freely and say, email the file, the email has no attachment. I think what is happening is my activity is deleting the file before it had been emailed. What I don't get is why, shouldn't onActivityResult only be called AFTER the other activity is finished? I have also tried deleting the file in onResume, but no luck. Is there a better way to do this?

  • Virtual Network Interface and NAT disables localhost access for MySQL and Apache

    - by Interarticle
    I'm running an Ubuntu Server 12.04, and recently I configured it to do NAT for my laptop. Since the server has only one NIC, I followed instructions online to create a virtual network device (eth0:0) that has a LAN IP address, then further configured iptables and UFW to allow internet sharing. However, just a few days ago, I discovered that one of the PHP pages hosted on the server failed for no apparent reason. A little digging revealed that the MySQL server started refusing connections from localhost. The same happened with a page (PhpMyAdmin) that was configured to be accessible only from localhost (in Apache2). The error, as shown by $mysql --protocol=tcp -u root -p looks like ERROR 1130 (HY000): Host '<host name of eth0>' is not allowed to connect to this MySQL server However, the funny thing is, I configured the mysql server to allow root access from localhost (only). Moreover, the mysql server listens only on 127.0.0.1:3306, as shown by: sudo netstat -npa | head Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 1029/mysqld which means that the connection could have only come from 127.0.0.1 (Note that MySQL is working because I can still connect to it via unix domain sockets) In effect, it seems that all tcp connections originating from 127.0.0.1 to 127.0.0.1 appear to any local daemon to come from the eth0 IP address. Indeed, apache2 allowed me to access PhpMyAdmin after I added allow <eth0 IP address>. The following are my network configurations (redacted): /etc/hosts: 127.0.0.1 localhost 211.x.x.x <host name of eth0> <server name> #IPv6 Defaults follows .... /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 211.x.x.x netmask 255.255.255.0 gateway 211.x.x.x dns-nameservers 8.8.8.8 # dns-* options are implemented by the resolvconf package, if installed dns-search xxxxxxx.com hwaddress ether xx:xx:xx:xx:xx:xx auto eth0:0 iface eth0:0 inet static address 192.168.57.254 netmask 255.255.254.0 broadcast 192.168.57.255 network 192.168.57.0 /etc/ufw/sysctl.conf: #Uncommented the following lines net/ipv4/ip_forward=1 net/ipv6/conf/default/forwarding=1 /etc/default/ufw: DEFAULT_FORWARD_POLICY="ACCEPT" #Changed DROP to ACCEPT /etc/init/internet-sharing.conf (upstart script I wrote), section pre-start script: iptables -A FORWARD -o eth0 -i eth0:0 -s 192.168.57.22 -m conntrack --ctstate NEW -j ACCEPT iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT iptables -A POSTROUTING -t nat -j MASQUERADE Note again that my problem here is that programs cannot access localhost tcp services, from the server itself, and that access is blocked because the services have access control allowing only 127.0.0.1. I have no problem connecting (as in TCP connections) to services via tcp, even if the services listen only on 127.0.0.1. I do NOT want to connect to the services from another computer.

  • Splitting an internet connection between multiple separate subnetworks

    - by pythonian4000
    Problem I have an internet connection that I want to split between four separate networks. My requirements are: I need to be able to monitor the amount of bandwidth and data being used by each network, and notify or control as necessary. The four networks should only be able to connect to the internet, not each other. My parents need to be able to operate it, so it needs a simple, preferably Windows-based GUI. Progress so far Server I have a mini-ITX server with six Gigabit ethernet ports - one for the ethernet internet connection, one for each of the four networks, and one for remote access to the server for administration. Bandwidth control I spent a long time researching solutions here. The majority of the control systems/software I found could control bandwidth usage via QOS, but could not monitor or control the amount of data being used. Eventually I found the SoftPerfect Bandwidth Manager, which has everything I need in terms of monitoring and control - per-interface quota management, usage statistics, a web interface for checking usage, and email notifications when quotas are exceeded. It is also Windows-based and has a simple GUI. Internet sharing This is where I am having issues. I am currently using Windows XP Pro SP2 for the server (yes, I know this is far from ideal, but it's the only spare Windows OS I currently have). I can't use the built-in Internet Connection Sharing for several reasons: The upstream internet router has an IP of 192.168.0.1 which ICS clashes with, and I cannot change the router settings. ICS can only share an internet connection with a single interface, but I have four. I have tried bridging the four network cards, but then the Bandwidth Manager cannot see the four individual interfaces - it only sees the bridge. I have tried setting up Dual DHCP DNS server (and am having issues getting DHCP offers to be received by clients), but that would still require gateway software of some sort, which I have been unable to find. My current attempt is to use OpenVPN, with a server for the internet NIC and a separate client for each of the four networks. My thought is that I could bridge the OpenVPN TAP devices to each NIC, meaning that the Bandwidth Manager would control traffic from the bridge instead of the interface. I have not made much progress here though - I've never used OpenVPN before. Questions Is there a Windows software package that does everything I need? (Unlikely, I know) Is there a Windows software package that will share internet between multiple NICs without bridging? Are either of my about attempts feasible? Would it help to have a newer/server version of Windows? Is there a non-Windows alternative that is easy to use?

  • Sync my files across multiple computers

    - by EnderMB
    I do a lot of work on my home computer, ranging from programming, writing stored procedures and writing documentation and reporting. A lot of this work is university related and constantly swapping files across several computers is annoying at best. I have a large final-year project coming up and I'm going to be sharing this work amongst home and university and require some kind of online storage that provides version control for my programs, as well as my Word documents, PDF's and saved academic papers. Are there any good solutions for my problem?

  • Improve file transfer speed between Windows PCs and servers

    - by Geotarget
    I've setup a server which I've connected to multiple PCs in my workplace. Sadly, data transfer speeds are at max 3 MB/sec per connection which works out slow for file transfers, especially when transferring large files. I'm using Windows filesharing and the server is a Windows Server 2008 (2 Ghz CPU, 1 GB RAM) and the client PCs mostly running Windows 7. How can I detect bottlenecks in my network and improve file sharing speed within the network?

  • Using Dropbox as a cloud based file share - does everyone need an upgraded account?

    - by aSkywalker
    We have a file share in our small office (3-5 users). We now have the need for the files to be accessible outside of the office. I like the idea of dropbox - we have been using it for small remote sharing. If we buy the upgrade account, and move 30 to 70 gigs of files to it, will every user have to have the pro account? I have submitted this question to dropbox - but thought that the advice of users here would also be valuable

  • Is it necessary to share every underlying folder in a Dropbox shared folder?

    - by ErnstvdS
    I have one Dropbox (I suppose) shared between my business account / PC and my wife's account / PC running Windows XP and a laptop with Windows 7. I created a folder and shared this one with both (or three) accounts. I created an underlying folder (no need to share, says the help) but it is not visible on the other PCs, so I've shared it to both accounts. Is this sharing necessary for every simple new folder?

  • How to troubleshoot port forwarding on Windows 7 (64 Bit) with ICS enabled?

    - by LearnCocos2D
    I want to forward some ports (1666 for perforce, 8081 for Hudson) on my Internet Gateway machine. This machine is running Windows 7 (64 Bit, legal, user-account) and connected to the Internet via cable modem (it's not a router). The Windows machine is sharing its Internet Connection via ICS and that works fine on all connected computers. I can access the services via the gateway's public IP (95.x.x.x) on the given ports if they are running on the gateway machine itself. I've added the ports and destination IP address (192.168.0.18) in the Internet network adapter's Advanced Settings dialog (Sharing tab). That's the same dialog where you have a list of preconfigured services like HTTP, FTP and other incoming services. When I do that I can't connect to the services anymore. For some reason port forwarding isn't working. I have uninstalled Bitdefender because I wanted to check if the Firewall interferes. I've also disabled the Windows Firewall and Defender to no avail. I tried a freeware tool that helps to setup port forwarding but that didn't work either. The target machine is a Mac OS X computer whose Firewall is disabled. The IP is static. I can successfully connect to the services using the local IP address (192.168.0.18) from two different machines, including the gateway computer. So internally and externally it seems to me that the ports are open and not blocked, and the issue is with port forwarding itself. From what I understand it should be enough to add an entry to the Advanced Settings dialog to enable port forwarding when there are no firewalls interfering. How can I troubleshoot why port forwarding isn't working for me? What steps should I follow to alleviate the issue? PS: I gladly accept command line solutions. Other things I've tried: adding an Inbound Rule to Windows Firewall for the 1666, 8081 ports trying with Windows Firewall enabled and disabled disabling/enabling the network adapter double-checked that the IP addresses are correct mapping a different incoming port to the service's actual port followed or checked the misc tips in this article What I haven't dared trying yet (let me know if it's worth a shot): disable/enable ICS remove all network adapters (via Control Panel), then re-install and re-configure them

  • Can a windows virus downloaded in linux be transferred to windows?

    - by user219048
    I know that linux is mostly safe from viruses, however: if you do download a windows virus (i.e., through a drive-by download), will it just sit there on your computer, and take up space? Is it unable to infect files because of the different operating system? If you transfer files between computers (by using a usb flash drive or through online file sharing), is there any risk that the virus could be transferred to windows and activate?

  • How to customize android analog clock widget through configuration screen

    - by michJ
    I'm trying to develop my own analog clock widget on the home screen. It's based on the stock ICS analog clock widget, but when added to the homescreen, my widget opens a configuration screen first. On this screen you can choose the color you want the clock to be (through a colorpicker dialog). You also see a preview of the clock in the chosen color on this screen. (See picture). My problem is changing the color of the widget on the home screen to the chosen color (when you hit the apply button). I have three .png files that I use for the dial, hour hand and minute hand. I color them using this code in my widgetconfig class: Drawable dial = getResources().getDrawable(R.drawable.clockbackground); dial.setColorFilter(color, PorterDuff.Mode.MULTIPLY); //hour Drawable hour = getResources().getDrawable(R.drawable.hourhand); hour.setColorFilter(color, PorterDuff.Mode.MULTIPLY); //minute Drawable min = getResources().getDrawable(R.drawable.minutehand); min.setColorFilter(color, PorterDuff.Mode.MULTIPLY); // clock AnalogClock clockpreview = (AnalogClock) findViewById(R.id.ACconfig); clockpreview.setBackgroundDrawable(dial); This works fine because I can find the AnalogClock since it's in the layout xml file of the configuration screen, which I set in the OnCreate() through setContentView(). The problem is that for the clock widget on my screen I have to use RemoteViews. So I tried setting the new background of the clock widget through RemoteViews. But RemoteViews seems too limited to do this. I need something like setTextViewText() but then for the background of my analog clock widget, like for example: RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.clockwidget); views.setAnalogClockBackgroundDrawable(dial); The clock widget background seems sort of unchangeable. How can I recolor my clockwidget on homescreen in widgetconfig class? There must be a way because it seems so easy to do at first... My project consists of the widget config class and clockwidget class, widgetconfig.xml, clockwidget.xml, and widget_info.xml (for appwidgetprovider).

  • Performing full screen grab in windows

    - by Steven Lu
    I am working an idea that involves getting a full capture of the screen including windows and apps, analyzing it, and then drawing items back onto the screen, as an overlay. I want to learn image processing techniques and I could get lots of data to work with if I can directly access the Windows screen. I could use this to build automation tools the likes of which have never been seen before. More on that later. I have full screen capture working for the most part. HWND hwind = GetDesktopWindow(); HDC hdc = GetDC(hwind); int resx = GetSystemMetrics(SM_CXSCREEN); int resy = GetSystemMetrics(SM_CYSCREEN); int BitsPerPixel = GetDeviceCaps(hdc,BITSPIXEL); HDC hdc2 = CreateCompatibleDC(hdc); BITMAPINFO info; info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); info.bmiHeader.biWidth = resx; info.bmiHeader.biHeight = resy; info.bmiHeader.biPlanes = 1; info.bmiHeader.biBitCount = BitsPerPixel; info.bmiHeader.biCompression = BI_RGB; void *data; hbitmap = CreateDIBSection(hdc2,&info,DIB_RGB_COLORS,(void**)&data,0,0); SelectObject(hdc2,hbitmap); Once this is done, I can call this repeatedly: BitBlt(hdc2,0,0,resx,resy,hdc,0,0,SRCCOPY); The cleanup code (I have no idea if this is correct): DeleteObject(hbitmap); ReleaseDC(hwind,hdc); if (hdc2) { DeleteDC(hdc2); } Every time BitBlt is called it grabs the screen and saves it in memory I can access thru data. Performance is somewhat satisfactory. BitBlt executes in 50 milliseconds (sometimes as low as 33ms) at 1920x1200x32. What surprises me is that when I switch display mode to 16 bit, 1920x1200x16, either through my graphics settings beforehand, or by using ChangeDisplaySettings, I get a massively improved screen grab time between 1ms and 2ms, which cannot be explained by the factor of two reduction in bit-depth. Using CreateDIBSection (as above) offers a significant speed up when in 16-bit mode, compared to if I set up with CreateCompatibleBitmap (6-7ms/f). Does anybody know why dropping to 16bit causes such a speed increase? Is there any hope for me to grab 32bit at such speeds? if not for the color depth, but for not forcing a change of screen buffer modes and the awful flickering.

  • Xvnc4 started from xinetd only displays empty gray X screen

    - by Scott Thomason
    Hi. I'm attempting to setup an Ubuntu 10.10 box so that anyone can connect to port 5900 and be greeted by the gdm login manager. To do so, I added a vnc entry in /etc/services and I am starting Xvnc4 using this xinetd config file: service vnc { protocol = tcp socket_type = stream wait = no user = nobody server = /usr/bin/Xvnc server_args = -geometry 1000x700 -depth 24 -broadcast -inetd -once -securitytypes None } This kind of works...I can start multiple sessions all to port 5900, and I get an X screen. The problem is that I only get an empty, gray X screen with no applications started. I know when you run vncserver from the command line it will look to your ~/.vnc/ directory for your passwd and xstartup files, and I think what I want to do is put "gnome-session" into the xstart file. However, which xstartup file? The running user is "nobody" who obviously doesn't have a ~/.vnc/ directory. I tried a /root/.vnc/xstartup file and a ~scott/.vnc/xstartup file and it doesn't look like they were even read. I changed the xinetd vnc service so that it would "strace" Xvnc4. I looked thru all the "open" lines and didn't get a clue as to what file it was trying to read for xstart. Can anyone help? I just want a terminal server where the user is presented with a gdm login screen.

  • redirect temporarily STDOUT to another file descriptor, but still to screen

    - by Carlos Campderrós
    I'm making a script that executes some commands inside, and these commands show some output on STDOUT (and STDERR as well, but that's no problem). I need that my script generates a .tar.gz file to STDOUT, so the output of some commands executed in the script also go to STDOUT and this ends with a not valid .tar.gz file in the output. So, in short, it's possible to output the first commands to the screen (as I still want to see the output) but not via STDOUT? Also I would like to keep the STDERR untouched so only error messages appear there. A simple example of what I mean. This would be my script: #!/bin/bash # the output of these commands shouldn't go to STDOUT, but still appear on screen some_cmd foo bar other_cmd baz #the following command creates a tar.gz of the "whatever" folder, #and outputs the result to STDOUT tar zc whatever/ I've tried messing with exec and the file descriptors, but I still can't get it to work: #!/bin/bash # save STDOUT to #3 exec 3>&1 # the output of these commands should go to #3 and screen, but not STDOUT some_cmd foo bar other_cmd baz # restore STDOUT exec 1>&3 # the output of this command should be the only one that goes to STDOUT tar zc whatever/ I guess I'm lacking closing STDOUT after the first exec and reopen it again or something, but I can't find the right way to do it (right now the result is the same as if I didn't add the execs

  • Citrix Metaframe/RD - screen refresh weirdness

    - by southof40
    I access a clients W2003 machine (XEN Virtualization) using RD over Citrix Metaframe. Everything used to be fine. Some weeks ago things turned bad ! All is well initially but after, say, 5 minutes the screen will stop refreshing. Rather weirdly you can then still proceed in a way as you can make the screen refresh by getting the RD window to go through a restore/maximise cycle (this is only possible using the ALT-BREAK shortcut as everything else is locked up). This then allows you to proceed by typing something and going ALT-BREAK to see the results. Using menus is just not possible at all. There's some indications that clearing the java cache between sessions helps. Also that the lockup happens more quickly if you make the 'lots of stuff happen' on the screen - for instance if you do a directory listing of a big directory then often that will cause the lockup to occur. Similary opening a dense Excel workbook and then scrolling it will cause the lockup to occur. Any Metaframe veterans out there who recognise these symptoms ? I'd be very grateful as it's driving me nuts.
