• SSL configuration issue. SSL/IIS7 not loading all scripts/CSS on user's first visit

  - by Chris

  Hi all, Hopefully this isnt a tricky one. I've got a web app that doesn't load all javascript/css/images on the first visit. Second visit is fine. After approximately 2 minutes of inactivity the problem reoccurs. These problems only started occuring after the customer requested SSL be applied to the application. Ajax requests stop working after 2 minutes of activity despite a successful page load of all javascript elements. Application timeout is 30 minutes - like I said, everything was fine before SSL was applied. All javascript and CSS files use absolute URLS - e.g https://blablabla There appears to be no pattern as to why certain files arent loaded. The firebug Net output shows the status for the failed elements as 'Aborted'. For example, site.css and nav.css are in the same folder, are declared after each other in the head tag yet one is loaded and the other is not. Both will load fine after refreshing the page (unless roughly two minutes have passed). An Ajax request also shows as aborted after two minutes. However, if i do the request again the Ajax request will succeed. Almost as if the first request woke something up. None of these problems occur in Chrome Any ideas? FYI this is a .Net 4 C# MVC app running under IIS7 but I'm not sure its relevant since it works in Chrome. Everything worked fine before SSL was applied. Originally posted on stackoverflow but recommended to list here. Can provide additional details if necessary.

• Install KVM based Windows 2008 remotely over SSH on a headless, no graphics Ubuntu 10.04 server?

  - by taazaa

  Hi, I have a Dell server at a remote data center with Ubuntu 10.04 as the host. It is a minimal install with the necessary virtulization packages. There is no X and the machine is headless. I have the win2008 DVD in the machine and want to remotely install it. I tried: virt-install --connect qemu:///system -n vmwin2k8 -r 1024 --disk path=server2k8.qcow2,size=50 --cdrom /dev/sr0 --vnc --noautoconsole --os-type windows --os-variant win2k8 The qcow2 image get created However I don't understand how to connect to see the install via VNC. This is my first time doing it so it may be trivial or may not be possible. Remotely I have a Win 7 machine with Putty and RealVNC viewer. Where is the graphic output of VNC going? Do I have to have VNC server running on the host or some other machine and then connect to it from my VNC client? Please let me know or point me to the right direction. I have been searching the web for several days to figure out how this is suppose to work. Thanks!

• Linux can dual display but windows can't?

  - by Mr_CryptoPrime

  I have two monitors, one that is hdmi-to-dvi and the other vga-to-dvi. I have an AMD HD Radeon 6900 series graphics card installed. I got Ubuntu to display dual monitors, but then I restarted for an update and then Ubuntu wouldn't even boot in recovery mode, it just kept cycling forever...displaying something about "timeout: killing [filepath] [hexadecimal]. So I tried booting into windows (7-professional) and it crashed and displayed this after rebooting: IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT-IN-NONPAGED-AREA. I went into Bios and reverted to the system defaults and ran system restore and it booted ok, but the dvi-to-dvi monitor would not display. I made sure my drivers were updated and catalyst was updated. Also through research discovered only one is for vga and the other is digital only, so I put the vga-to-dvi in the vga slot and so on. Neither windows or catalyst will detect the dvi-to-dvi montior. Any suggestions? Thanks. EDIT: Found out that booting into Ubuntu with only one monitor (using either monitor with either cable) worked perfectly fine. I could then add another monitor and it displays ok. However, it will, out of the blue, suddenly distort the display. At first I thought the computer crashed, but it is something with the video output from the GPU to the monitor because I pushed the power button and it would refresh every 5secs or so and I could see the "Ubuntu will power down in X seconds", even though it was horribly distorted. Any ideas what's causing this?

• Hard Reset USB in Ubuntu 10.04

  - by Cory

  I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: $ sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: $ sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on serverfault as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

• Configuring iptables rules for HAProxy and others

  - by MLister

  I have the following relevant settings for HAProxy: defaults log global mode http option httplog option dontlognull retries 3 option redispatch maxconn 500 contimeout 5s clitimeout 15s srvtimeout 15s frontend public bind *:80 option http-server-close option http-pretend-keepalive option forwardfor # ACLs ... I have three backends (including a Nginx server) configured in HAProxy, all listening on different ports of 127.0.0.1. And my iptables config is this: *filter # Allows all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0 -A INPUT -i lo -j ACCEPT -A INPUT -i lo -d 127.0.0.0/8 -j REJECT # Accepts all established inbound connections -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allows all outbound traffic # You can modify this to only allow certain traffic -A OUTPUT -j ACCEPT # Allows HTTP and HTTPS connections from anywhere (the normal ports for websites) -A INPUT -p tcp --dport 80 -j ACCEPT -A INPUT -p tcp --dport 443 -j ACCEPT # Allows SSH connections # # THE -dport NUMBER IS THE SAME ONE YOU SET UP IN THE SSHD_CONFIG FILE # -A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT # Allow ping -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT # log iptables denied calls -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7 # Reject all other inbound - default deny unless explicitly allowed policy -A INPUT -j REJECT -A FORWARD -j REJECT COMMIT My questions are: Would the above iptables config work with the settings/options in my HAProxy config? I am also runnning a postgres and a redis server on the same machine, what settings do I need to adjust for these two to enable them work with iptables?

• What Logs / Process Stats to monitor on a Ubuntu FTP server?

  - by Adam Salkin

  I am administering a server with Ubuntu Server which is running pureFTP. So far all is well, but I would like to know what I should be monitoring so that I can spot any potential stability and security issues. I'm not looking for sophisticated software, more an idea of what logs and process statistics are most useful for checking on the health of the system. I'm thinking that I can look at various parameters output from the "ps" command and compare to see if I have things like memory leaks. But I would like to know what experienced admins do. Also, how do I do a disk check so that when I reboot, I don't get a message saying something like "disk not checked for x days, forcing check" which delays the reboot? I assume there is command that I can run as a cron job late at night. How often should it be run? What things should I be looking at to spot intrusion attempts? The only shell access is SSH on a non-standard port through UFW firewall, and I regularly do a grep on auth.log for "Fail" or "Invalid". Is there anything else I should look at? I was logging the firewall (UFW) but I have very few open ports (FTP and SSH on a non standard port) so looking at lists of IP's that have been blocked did not seem useful. Many thanks

• Passive mode FTP file download hangs from specific machine

  - by chiptuned

  I have a server which is an AWS instance that just cannot download files from a specific FTP server. I can connect to the FTP server fine and run some commands, but when I request a file it just hangs. Here is the debug output of the base linux ftp client after login: ---> SYST 215 UNIX Type: Apache FtpServer Remote system type is UNIX. ftp> get outgoing/catalog.gz catalog.gz local: catalog.gz remote: outgoing/catalog.gz ---> PASV 227 Entering Passive Mode (64,156,167,125,135,191) ---> RETR outgoing/catalog.gz 150 File status okay; about to open data connection. Thats it. Then it just sits there and nothing transfers. I have verified that a data connection is made but the client gets no data. ? ss -nt dst 64.156.167.125 State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 0 10.185.147.150:41190 64.156.167.125:21 ESTAB 0 0 10.185.147.150:48871 64.156.167.125:48557 The FTP server is not in my control and downloads from other FTP servers in passive mode have worked. Active mode does not work as the system is behind a firewall. Every FTP client I've tried has the same problem. The download works from other systems, even from other AWS instances I have with the same Security Group. Not necessarily the same distro or config though. I understand it may be some issue on the server side, but I want to know what it is about my particular machine where the transfer hangs and where on every other machine I can get my hands on, it works. Please let me know what the culprit on the client side could be or ideas on what else to look at.

• How to block access to addresses outside network (internet)

  - by devnull

  I have a homeserver, that is now connected to the internet with an own network device (ath0 - 192.168.1.x). It also has one more network interface (eth0 - 192.168.0.x). Soon I will get a second internet line that will be connected the second network. The server then has both networks with different internet lines available, but i only want it to connect to the internet on the old ath0 interface - not the new eth0 (192.168.0.x). Background of that constellation is that the new line has a volume-limit in traffic - the old hasn't and i need the new line for all mobile devices and laptops. The devices should be able to use the new network to connect to the internet and the server. The homeserver is a debian 6 with iptables and some already written rules for it. I need now a rule to block all outgoing internet access on the eth0 interface - i guess it could be something with --target != 192.168.0.0 but i did not succeed in finding the proper solution. Edit: found the solution: iptables -A OUTPUT -o eth0 -d 192.168.0.0/24 -m state --state NEW,ESTABLISHED -j ACCEPT With that setting, all traffic that uses the eth0 interface is only allowed if the destination is inside the network 192.168.0.x - all other traffic is denied .

• Fedora 17 transparent Ethernet Bridge not forwarding IP traffic

  - by mcdoomington

  I am running on Fedora 17 with the latest ebtables and have been trying to setup a transparent bridge - using the following script, I send a ping through the bridged host and only see the requests on the bridge (among other traffic from eth0), BUT, arps and arp replies are making it through.

• Using iptables to make a VPN router

  - by lost_in_the_sauce

  I am attempting to make a VPN connection to a third party VPN site, then forward traffic from my internal computers (ssh and ping for now) out to the VPN site using IPTables. 3rd Party <- (tun0/eth0)Linux VPN Box(eth1) <- Windows7TestBox I am running on CentOS 6.3 Linux and have two network connections eth0-public eth1-private. I am running vpnc-0.5.3-4 which is currently connecting to my destination. When I connect I am able to ping the destination IPAddresses but that is as far as I can get. ping -I tun0 10.1.33.26 success ping -I eth0 10.1.33.26 fail ping -I eth1 10.1.33.26 fail I have my private network Windows 7 test box set up to have the eth1 (private) network of my VPN Server as its gateway and can ping him fine. I need IPTables to send the Windows 7 traffic out the VPN tunnel. I have tried for a few days many different IPTables configurations from this site and others, either the other examples are too simple or overly complicated. The only thing this server is doing is connecting to the VPN and forwarding all traffic. So we can "flush" everything and start from scratch here. It is a blank slate. #!/bin/bash echo "Define variables" ipt="/sbin/iptables" echo "Zero out all counters" $ipt -Z $ipt -t nat -Z $ipt -t mangle -Z echo "Flush all active rules, delete all chains" $ipt -F $ipt -X $ipt -t nat -F $ipt -t nat -X $ipt -t mangle -F $ipt -t mangle -X $ipt -P INPUT ACCEPT $ipt -P FORWARD ACCEPT $ipt -P OUTPUT ACCEPT $ipt -t nat -A POSTROUTING -o tun0 -j MASQUERADE $ipt -A FORWARD -i eth1 -o eth0 -j ACCEPT $ipt -A FORWARD -i eth0 -o eth1 -j ACCEPT $ipt -A FORWARD -i eth0 -o tun0 -j ACCEPT $ipt -A FORWARD -i tun0 -o eth0 -j ACCEPT Again I have done many variations of the above and many other rules from other posts but haven't been able to move forward. It seems like such a simple task, and yet....

• Duplicate monitor on highest resolution in Windows 7

  - by AlexanderMP

  I have a monitor with a native resolution of 2560x1440, connected through display port. I also have an AV Receiver connected to the video card via HDMI, to have surround sound in games. All using Radeon HD 5670 (will upgrade soon to HD 7850). The problem is that my computer detects the receiver as a separate monitor, with the highest available resolution of 1920x1080. I have 3 options: Disconnect the second display. But then the sound (digital audio output through video card) also disappears. Duplicate displays. But then my primary monitor resolution is reduced to a maximum of just 1920x1080, that being the maximum of the second monitor. Extend desktop. This is the solution I picked so far, it being the least evil. The problems I face in this situations are 2: I have a blank part of the desktop where I sometimes lose my mouse pointer, so I made the extension small, 640x480, and placed it in a corner; when I turn off the main display, all windows resize to 640x480. In Kubuntu I had the option to duplicate the displays, while keeping the higher resolution. Which was great. I tried overriding using the Win7 netbook hack, but it's not available on non-netbooks. Is there a similar solution for this problem in Windows 7?

• cannot connect to my nginx server from remote machine

  - by margincall

  I thought that it's iptables problem.. but it seems not. I really have no idea about this situation. I'm getting a server hosting(CentOS). I installed Nginx + Django and nginx uses 8080 port. A domain is connected to the server. When I executed "wget [domain]:8080/[app name]/" in the server, it worked. Of course, "wget 127.0.0.1:8080/[app name]/" has no problem. (wget [server ip]:8080/[app name]/, either) However, from other computers, connecting was failed. (message says, no route) I checked my firewall setting. I excuted these commands. iptables -I INPUT -p tcp --dport 8080 -j ACCEPT iptables -I OUTPUT -p tcp --sport 8080 -j ACCEPT iptables -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT /etc/init.d/iptables restart I don't really understand all options of commands and I think there were useless commands, but I just tried all googled iptables settings. But still I cannot connect to my server. What should I check, first? I don't know this is important, but add to this post. On 80 port, an apache server is running. It works fine, I can connect to apache from other computers. There is DB connecting issue, (PHP to MySQL) but I think that it is just PHP coding bug. please excuse my low-level English. I'm not native English speaker.. but I tried to explane well as far as possible. Thank you for reading this question.

• SSH very slow when connecting from external [closed]

  - by wnstnsmth

  Possible Duplicate: ssh delay when connecting We have a CentOS server that we use for internal testing purposes, which has sshd enabled. When I (as a developer) am at the company, I use ssh [email protected] to connect to it - and it works flawlessly. Now, in order to work from home, accessing the server via the company's static IP, we set up another port for ssh, 2020. So I execute ssh -p 2020 [email protected] and am immediately granted for a password. After entering the password, it takes up to 30 seconds until I can access the server. Same is with SFTP (i.e. uploading files takes about 30 seconds until it begins to transfer). As you can imagine, if you have to regularly upload files to a webserver via SFTP, this is very tedious. So I looked at similar questions and thus edited the sshd_config file on the server, setting UseDNS to "no" and GSSAPIAuthentication to "no" (this one also in ssh_config on the client) - it did not work.. Please have a look at the -vvv output when externally accessing the server: ssh -p 2020 -vvv [email protected] PasteBin: ssh What could it be? Do you need more info?

• Open source app to manage and run commands on cloud servers? [closed]

  - by Mark Theunissen

  I'm creating a SaaS platform, and I need a component / library that can create, delete and store the connection details for cloud servers. It also needs to support executing shell commands on these servers and returning the response to the caller. I want a central database of servers and their configuration, plus the ability to reach out and manage the servers via SSH execution of bash scripts. I don't want something that needs agents on every server like Chef. For example, this command is received by the hypothetical application: CREATE USER server = server12345 name = myuser It's translated into the following set of actions and executed by the app, which knows how to connect to server12345, and how to create a user on that server: $ ssh root@server12345 $ adduser myuser And returns the output from the shell: Added user myuser. I've done research on Google and can't quite quite find something that does this already. I've found: fabric This part handles the executing of the shell commands very elegantly, and can take multiple server definitions, but it's supposed to be a deployment tool so doesn't do everything that would be required above - for example, it doesn't have a daemon mode where it listens for commands - it expects to be executed on the shell. It also can't provide the central database functionality. libcloud This library can handle the server admin (CRUD) part, but doesn't have a command interface daemon either, and doesn't let you execute commands on the servers. I guess I need something that is a combination of libcloud, fabric and django for an API. Or something else that does that same thing regardless of language. Overmind Overmind is a GUI and wrapper around libcloud, but doesn't support the command execution part. What am I missing here?

• Cannot open /dev/rfcomm1 : Host is down

  - by srj0408

  I am working on raspberry PI and on Bluetooth. I am using old raspberry pi kernel as the new one has got some bugs that were not resolved with respect to the bluez daemon. At present my kernel version is 3.6.11. I am using a USB bluetooth dongle and my sole purpose is to auto connect the bluetooth dongle when ever it is in range. For that i think i have to run a script in the backend on RPI that will keep on checking the existence of usb bluetooth dongle. I started from the very scratch. I installed bluez daemon using apt-get install bluetooth bluez utils blueman and then i used hciconfig which gives me that my bluetooth usb dongle is working fine. But when i did hcitool scan , it give me no device in range even though my Serial bluetooth Device was on. I wasn't able to find any device in vicinity. Also when i unplugged and plug the USB dongle again, i was able to scan the serial device , but when i repeat the process, i find the earlier condition of not finding any deice. I had find another useful link, but that need address of the bluetooth device that need to be connected. I want to automate this using hcitool scan, storing the output to the a file and then comparing it with already paired devices and their name. For that i need to figure out why hcitool scan is sometime working and sometime not. ? Can some one help me in figuring out why this is happening. Is there any problem on hardware side i.e Bluetooth dongle is buggy or i had some problem in bluez utils. Edit 1: While as of now, hcitool scan is giving me my remote device address but still i am getting the same issue of HOUST IS DOWN, '/dev/rfcomm1'. I am really not getting any idea of what to be done.

• Set the JAXB context factory initialization class to be used

  - by user1902288

  I have updated our projects (Java EE based running on Websphere 8.5) to use a new release of a company internal framework (and Ejb 3.x deployment descriptors rather than the 2.x ones). Since then my integration Tests fail with the following exception: [java.lang.ClassNotFoundException: com.ibm.xml.xlxp2.jaxb.JAXBContextFactory] I can build the application with the previous framework release and everything works fine. While debugging i noticed that within the ContextFinder (javax.xml.bind) there are two different behaviours: Previous Version (Everything works just fine): None of the different places brings up a factory class so the default factory class gets loaded which is com.sun.xml.internal.bind.v2.ContextFactory (defined as String constant within the class). Upgraded Version (ClassNotFound): There is a resource "META-INF/services/javax.xml.bind.JAXBContext" beeing loaded successfully and the first line read makes the ContextFinder attempt to load "com.ibm.xml.xlxp2.jaxb.JAXBContextFactory" which causes the error. I now have two questions: What sort is that resource? Because inside our EAR there is two WARs and none of those two contains a folder services in its META-INF directory. Where could that value be from otherwise? Because a filediff showed me no new or changed properties files. No need to say i am going to read all about the JAXB configuration possibilities but if you have first insights on what could have gone wrong or help me out with that resource (is it a real file i have to look for?) id appreciate a lot. Many Thanks! EDIT (according to comments Input/Questions): Out of curiosity, does your framework include JAXB JARs? Did the old version of your framework include jaxb.properties? Indeed (i am a bit surprised) the framework has a customized eclipselink-2.4.1-.jar inside the EAR that includes both a JAXB implementation and a jaxb.properties file that shows the following entry in both versions (the one that finds the factory as well as in the one that throws the exception): javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory I think this is has nothing to do with the current issue since the jar stayed exactly the same in both EARs (the one that runs/ the one with the expection) It's also not clear to me why the old version of the framework was ever selecting the com.sun implementation There is a class javax.xml.bind.ContextFinder which is responsible for initializing the JAXBContextFactory. This class searches various placess for the existance of a jaxb.properties file or a "javax.xml.bind.JAXBContext" resource. If ALL of those places dont show up which Context Factory to use there is a deault factory loaded which is hardcoded in the class itself: private static final String PLATFORM_DEFAULT_FACTORY_CLASS = "com.sun.xml.internal.bind.v2.ContextFactory"; Now back to my problem: Building with the previous version of the framework (and EJB 2.x deployment descriptors) everything works fine). While debugging i can see that there is no configuration found and thatfore above mentioned default factory is loaded. Building with the new version of the framework (and EJB 3.x deployment descriptors so i can deploy) ONLY A TESTCASE fails but the rest of the functionality works (like i can send requests to our webservice and they dont trigger any errors). While debugging i can see that there is a configuration found. This resource is named "META-INF/services/javax.xml.bind.JAXBContext". Here are the most important lines of how this resource leads to the attempt to load 'com.ibm.xml.xlxp2.jaxb.JAXBContextFactory' which then throws the ClassNotFoundException. This is simplified source of the mentioned javax.xml.bind.ContextFinder class: URL resourceURL = ClassLoader.getSystemResource("META-INF/services/javax.xml.bind.JAXBContext"); BufferedReader r = new BufferedReader(new InputStreamReader(resourceURL.openStream(), "UTF-8")); String factoryClassName = r.readLine().trim(); The field factoryClassName now has the value 'com.ibm.xml.xlxp2.jaxb.JAXBContextFactory' (The day i understand how to format source code on stackoverflow will be my biggest step ahead.... sorry for the formatting after 20 mins it still looks the same :() Because this has become a super lager question i will also add a bounty :)

• Silverlight 3 Dynamic DataGrid RowStyle Ignored

  - by antoinne85

  I subclassed the standard DataGrid into SpecialDataGrid so I could override the KeyDown/KeyUp events. Other than that SpecialDataGrid is exactly the same as DataGrid. At run-time I dynamically create a bunch of these SpecialDataGrids. When a user clicks a row in the grid it hightlights, which is fine, but when that grid loses focus, it leaves a residual gray highlight on the last-selected row, which is not fine. I've heavily edited the RowStyle and CellStyle I'm applying to these Grids to more-or-less remove all formatting. I even added a static SpecialDataGrid to the app with test data so I could see if the RowStyle was somehow incorrect, applying the same RowStyle and CellStyle that I'm applying to the dynamically generated one (you'll see it in the code below). What I saw was that the "test grid" showed up exactly as I wanted, and the real grid is ignoring part of the RowStyle! Has anyone run into this issue or have any ideas of how to correct it? Some source and images follow. Creating the SpecialDataGrid: //Set up a datagrid. SpecialDataGrid radio_datagrid = new SpecialDataGrid(); radio_datagrid.ItemsSource = radios; radio_datagrid.AutoGenerateColumns = false; radio_datagrid.HeadersVisibility = DataGridHeadersVisibility.None; radio_datagrid.BorderThickness = new Thickness(0); radio_datagrid.HorizontalAlignment = HorizontalAlignment.Stretch; radio_datagrid.IsReadOnly = true; radio_datagrid.MouseLeftButtonUp += new MouseButtonEventHandler(option_datagrid_MouseLeftButtonUp); radio_datagrid.KeyDown += new KeyEventHandler(radio_datagrid_KeyDown); radio_datagrid.KeyUp += new KeyEventHandler(radio_datagrid_KeyUp); //Radio column. DataGridTemplateColumn temp_col = new DataGridTemplateColumn(); temp_col.CellTemplate = (DataTemplate)this.Resources["RadioColumnTemplate"]; temp_col.Width = new DataGridLength(20); radio_datagrid.Columns.Add(temp_col); //Description column. DataGridTextColumn txt_col = new DataGridTextColumn(); txt_col.Binding = new Binding("optionlabel"); txt_col.Width = new DataGridLength(350); radio_datagrid.Columns.Add(txt_col); //Product code column. txt_col = new DataGridTextColumn(); txt_col.Binding = new Binding("optioncode"); txt_col.Width = new DataGridLength(80); radio_datagrid.Columns.Add(txt_col); //Price column. txt_col = new DataGridTextColumn(); txt_col.Binding = new Binding("optionprice"); txt_col.Width = new DataGridLength(80); radio_datagrid.Columns.Add(txt_col); //View column. temp_col = new DataGridTemplateColumn(); temp_col.CellTemplate = (DataTemplate)this.Resources["HyperlinkButtonColumnTemplate"]; temp_col.Width = new DataGridLength(30); radio_datagrid.Columns.Add(temp_col); radio_datagrid.RowStyle = (Style)this.Resources["StyleDataGridRowNoAlternating"]; radio_datagrid.CellStyle = (Style)this.Resources["Style_DataGridCell_NoHighlight"]; Example Image: The lower DataGrid appears that way regardless of what you do to it. No highlighting of any sort and certainly no residual highlights. Any idea what's keeping this from being applied to the first?

• overriding ctype<wchar_t>

  - by Potatoswatter

  I'm writing a lambda calculus interpreter for fun and practice. I got iostreams to properly tokenize identifiers by adding a ctype facet which defines punctuation as whitespace: struct token_ctype : ctype<char> { mask t[ table_size ]; token_ctype() : ctype<char>( t ) { for ( size_t tx = 0; tx < table_size; ++ tx ) { t[tx] = isalnum( tx )? alnum : space; } } }; (classic_table() would probably be cleaner but that doesn't work on OS X!) And then swap the facet in when I hit an identifier: locale token_loc( in.getloc(), new token_ctype ); … locale const &oldloc = in.imbue( token_loc ); in.unget() >> token; in.imbue( oldloc ); There seems to be surprisingly little lambda calculus code on the Web. Most of what I've found so far is full of unicode ? characters. So I thought to try adding Unicode support. But ctype<wchar_t> works completely differently from ctype<char>. There is no master table; there are four methods do_is x2, do_scan_is, and do_scan_not. So I did this: struct token_ctype : ctype< wchar_t > { typedef ctype<wchar_t> base; bool do_is( mask m, char_type c ) const { return base::do_is(m,c) || (m&space) && ( base::do_is(punct,c) || c == L'?' ); } const char_type* do_is (const char_type* lo, const char_type* hi, mask* vec) const { base::do_is(lo,hi,vec); for ( mask *vp = vec; lo != hi; ++ vp, ++ lo ) { if ( *vp & punct || *lo == L'?' ) *vp |= space; } return hi; } const char_type *do_scan_is (mask m, const char_type* lo, const char_type* hi) const { if ( m & space ) m |= punct; hi = do_scan_is(m,lo,hi); if ( m & space ) hi = find( lo, hi, L'?' ); return hi; } const char_type *do_scan_not (mask m, const char_type* lo, const char_type* hi) const { if ( m & space ) { m |= punct; while ( * ( lo = base::do_scan_not(m,lo,hi) ) == L'?' && lo != hi ) ++ lo; return lo; } return base::do_scan_not(m,lo,hi); } }; (Apologies for the flat formatting; the preview converted the tabs differently.) The code is WAY less elegant. I does better express the notion that only punctuation is additional whitespace, but that would've been fine in the original had I had classic_table. Is there a simpler way to do this? Do I really need all those overloads? (Testing showed do_scan_not is extraneous here, but I'm thinking more broadly.) Am I abusing facets in the first place? Is the above even correct? Would it be better style to implement less logic?

• ListView: convertView / holder getting confused

  - by Steve H

  I'm working with a ListView, trying to get the convertView / referenceHolder optimisation to work properly but it's giving me trouble. (This is the system where you store the R.id.xxx pointers in as a tag for each View to avoid having to call findViewById). I have a ListView populated with simple rows of an ImageView and some text, but the ImageView can be formatted either for portrait-sized images (tall and narrow) or landscape-sized images (short and wide). It's adjusting this formatting for each row which isn't working as I had hoped. The basic system is that to begin with, it inflates the layout for each row and sets the ImageView's settings based on the data, and includes an int denoting the orientation in the tag containing the R.id.xxx values. Then when it starts reusing convertViews, it checks this saved orientation against the orientation of the new row. The theory then is that if the orientation is the same, then the ImageView should already be set up correctly. If it isn't, then it sets the parameters for the ImageView as appropriate and updates the tag. However, I found that it was somehow getting confused; sometimes the tag would get out of sync with the orientation of the ImageView. For example, the tag would still say portrait, but the actual ImageView would still be in landscape layout. I couldn't find a pattern to how or when this happened; it wasn't consistent by orientation, position in the list or speed of scrolling. I can solve the problem by simply removing the check about convertView's orientation and simply always set the ImageView's parameters, but that seems to defeat the purpose of this optimisation. Can anyone see what I've done wrong in the code below? static LinearLayout.LayoutParams layoutParams; (...) public View getView(int position, View convertView, ViewGroup parent){ ReferenceHolder holder; if (convertView == null){ convertView = inflater.inflate(R.layout.pick_image_row, null); holder = new ReferenceHolder(); holder.getIdsAndSetTag(convertView, position); if (data[position][ORIENTATION] == LANDSCAPE) { // Layout defaults to portrait settings, so ImageView size needs adjusting. // layoutParams is modified here, with specific values for width, height, margins etc holder.image.setLayoutParams(layoutParams); } holder.orientation = data[position][ORIENTATION]; } else { holder = (ReferenceHolder) convertView.getTag(); if (holder.orientation != data[position][ORIENTATION]){ //This is the key if statement for my question switch (image[position][ORIENTATION]) { case PORTRAIT: // layoutParams is reset to the Portrait settings holder.orientation = data[position][ORIENTATION]; break; case LANDSCAPE: // layoutParams is reset to the Landscape settings holder.orientation = data[position][ORIENTATION]; break; } holder.image.setLayoutParams(layoutParams); } } // and the row's image and text is set here, using holder.image.xxx // and holder.text.xxx return convertView; } static class ReferenceHolder { ImageView image; TextView text; int orientation; void getIdsAndSetTag(View v, int position){ image = (ImageView) v.findViewById(R.id.pickImageImage); text = (TextView) v.findViewById(R.id.pickImageText); orientation = data[position][ORIENTATION]; v.setTag(this); } } Thanks!

• java - BigDecimal

  - by Mk12

  I was trying to make my own class for currencies using longs, but Apparently I should use BigDecimal (and then whenever I print it just add the $ sign before it). Could someone please get me started? What would be the best way to use BigDecimals for Dollar currencies, like making it at least but no more than 2 decimal places for the cents, etc. The api for BigDecimal is huge, and I don't know which methods to use. Also, BigDecimal has better precision, but isn't that all lost if it passes through a double? if I do new BigDecimal(24.99), how will it be different than using a double? Or should I use the constructor that uses a String instead? EDIT: I decided to use BigDecimals, and then use: private static final java.text.NumberFormat moneyt = java.text.NumberFormat.getCurrencyInstance(); { money.setRoundingMode(RoundingMode.HALF_EVEN); } and then whenever I display the BigDecimals, to use money.format(theBigDecimal). Is this alright? Should I have the BigDecimal rounding it too? Because then it doesn't get rounded before it does another operation.. if so, could you show me how? And how should I create the BigDecimals? new BigDecimal("24.99") ? Well, after many comments to Vineet Reynolds (thanks for keeping coming back and answering), this is what I have decided. I use BigDecimals and a NumberFormat. Here is where I create the NumberFormat instance. private static final NumberFormat money; static { money = NumberFormat.getCurrencyInstance(Locale.CANADA); money.setRoundingMode(RoundingMode.HALF_EVEN); } Here is my BigDecimal: private final BigDecimal price; Whenever I want to display the price, or another BigDecimal that I got through calculations of price, I use: money.format(price) to get the String. Whenever I want to store the price, or a calculation from price, in a database or in a field or anywhere, I use (for a field): myCalculatedResult = price.add(new BigDecimal("34.58")).setScale(2, RoundingMode.HALF_EVEN); .. but I'm thinking now maybe I should not have the NumberFormat round, but when I want to display do this: System.out.print(money.format(price.setScale(2, RoundingMode.HALF_EVEN); That way to ensure the model and things displayed in the view are the same. I don't do: price = price.setScale(2, RoundingMode.HALF_EVEN); Because then it would always round to 2 decimal places and wouldn't be as precise in calculations. So its all solved now, I guess. But is there any shortcut to typing calculatedResult.setScale(2, RoundingMode.HALF_EVEN) all the time? All I can think of is static importing HALF_EVEN... EDIT: I've changed my mind a bit, I think if I store a value, I won't round it unless I have no more operations to do with it, e.g. if it was the final total that will be charged to someone. I will only round things at the end, or whenever necessary, and I will still use NumberFormat for the currency formatting, but since I always want rounding for display, I made a static method for display: public static String moneyFormat(BigDecimal price) { return money.format(price.setScale(2, RoundingMode.HALF_EVEN)); } So values stored in variables won't be rounded, and I'll use that method to display prices.
