  • Where can I get a theme/template suitable for a webapp?

    - by swisstony
    I'm building a simple web application that is mainly going to be displaying small tables of data back to the user. The problem is I can't do design to save my life. I need a simple web 2.0 style template that is CSS/HTML compliant. I know about http://themeforest.net and http://www.oswd.org/. Just wondering if there are any other sites that have a good selection of templates suitable for web apps.

  • How to fix Windows XP from muting sounds on every startup?

    - by Rookie
    This started to happen few days ago: Every time I start up my computer, the global sound volume ("Playback") is set to muted (from the checkbox), in the sound control panel. So I have to open the control panel every time i start up my computer, and click that checkbox. I have got this bug before, long time ago. I have no idea why is this happening. Any ideas how to fix this or what is causing it? I have SP 3 and most updates installed a half year ago or less.

  • rake db:create gives some problem when used from limited account

    - by Xinxua
    I am using mysql 5.1 and mysql gems version is 2.73 This is giving the following error message when I try to run it from a limited account in my XP. If try it using the admin account, it works fine. I think this is wierd because it cannot be the problem of mysql gem. (in F:/Temp/wassup) !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! 5: Access is denied. - C:/Program Files/Ruby/lib/ruby/gems/1.8/gems/mysql-2.7. 3-x86-mswin32/ext/mysql.so (See full trace by running task with --trace) I need to work from the limited account.

  • PL/SQL execption and Java programs

    - by edwards
    Hi Business logic is coded in pl/sql paackages procedures and functions. Java programs call pl/sql packages procedures and functions to do database work. Issue now is pl/sql programs store excpetions into Oracle tables whenever a execption is raised. How would my java programs get the execptions since the exception instead of being propogated from pl/sql to java is getting persisted to a oracle table.

  • Basic Database Design

    - by Thurein
    Hi, This question would be a bit childish, I have three tables, users, usergroups and contacts. In my system, the end user can create a contact and subsequently he\she may define the visibility of the contact by setting only for that user, or for a set of users or a set of usergroups. So I am wondering, how my database design would be, it should be many to many between users and contacts or many to many between usergroups and contacts. Definitely there is a one to many relationship between users and usergroups. Thanks Thurein

  • How can I center something if I don't know ahead of time what the width is?

    - by zeckdude
    I am trying to center a paragraph tag with some text in it within a div, but I can't seem to center it using margin: 0 auto without having to specify a fixed width for the paragraph. I don't want to specify a fixed width, because I will have dynamic text coming into the paragraph tag and it will always be a different width based on how much text it is. Does anyone know how I can center the paragraph tag within the div without having to specify a fixed width for the paragraph or without using tables?

  • Keeping DB Table sorted using multi-field formula (Microsoft SQL Server)

    - by user298167
    I have a JOB table, with two interesting columns: Creation Date Importance (high - 3, medium 2, low - 1). A JOB record's priority calculated like this: Priority = Importance * (time passed since creation) The problem is, every time I would like to pick 200 jobs with highest priority, and I don't want to resort the table. Is there a way to keep rows sorted? I was also thinking about having three tables one for High, Medium and Low and then sort those by Creation Date.

  • How do I create a stored procedure that calls sp_refreshview for each view in the database?

    - by Allrameest
    Today I run this select 'exec sp_refreshview N''['+table_schema+'].['+table_name+']''' from information_schema.tables where table_type = 'view' This generates a lot of: exec sp_refreshview N'[SCHEMA].[TABLE]'. I then copy the result to the query editor window and run all those execs. How do I do this all at once? I would like to have a stored procedure called something like dev.RefreshAllViews which I can execute to do this...

  • How can I make a web-based "table" select like a spreadsheet? (rectangular area vs row-wrap selecti

    - by Dax
    I want to make a table that displays on a webpage, but one requirement is to make it easy to copy and paste into a spreadsheet. Normal HTML tables selection behavior is obviously different from how a spreadsheet like Excel selects -- when you select multiple rows it wraps around instead of selecting a rectangular area. Is there any way to make HTML table behave like a spreadsheet in this regard, or is the only way to resort to a Flash table or something similar?

  • Rejecting new HTTP requests when server reaches a certain throughput

    - by Sam
    I have a requirement to run an HTTP server that rejects new HTTP requests (with a 503, or similar) when the global transfer rate of current HTTP responses exceeds a certain level. For example, if the web server is transferring at 98Mbps, and a new HTTP request arrives, we would want to reject this (as we couldn't guarantee a good speed). I've had a look at mod_cband for Apache, limit_req for nginx, and lighttpd's rate limiting features, but none of them seem to handle my (rather contrived, granted) use case. I should add that I'm open to using pretty much any web server, and am open to implementing this in iptables rules if someone can craft such a rule! (Refusing the TCP connection is fine, it doesn't have to respond with an HTTP 503). Any suggestions?

  • Tutorial for Examine/Lucene

    I am interested in Examine for building searching in a standalone desktop app for searching db tables as well as office/.pdf files This looks like an excellent scenario for Lucene/examine However the doc there is minimal and while i have plenty of experience with SQL full text search, Lucene is a different beast altogether and hence looking for help/pointers on how/where to start And yes, i did a google search but did not find any resources as the terms are fairly common ( lucene examine tutorial etc. )

  • Log4net appender filename issue

    - by JL
    I have an appender setup like this <appender name="Scheduler_Appender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\ApplicationLog.txt"/> <rollingStyle value="Date"/> <datePattern value="yyyyMMdd"/> <appendToFile value="true"/> <staticLogFileName value="true"/> <layout type="MinLayout"> <locationInfo value="true"/> </layout> </appender> When the log file first gets created the file name is simply ApplicationLog.txt this is correct. However when the logging rolls - the filename that gets generated is ApplicationLog.txt20100323 (for example), and not ApplicationLog20100323.txt How can I change the configuration so files are rolled to [FileName][Date].[ext] rather than [FileName].[ext][Date] Thanks

  • Magento - Data is not inserted into database, but the id is autoincremented

    - by Joseph
    I am working on a new payment module for Magento and have come across an issue that I cannot explain. The following code that runs after the credit card is verified: $table_prefix = Mage::getConfig()->getTablePrefix(); $tableName = $table_prefix.'authorizecim_magento_id_link'; $resource = Mage::getSingleton('core/resource'); $writeconnection = $resource->getConnection('core_write'); $acPI = $this->_an_customerProfileId; $acAI = $this->_an_customerAddressId; $acPPI = $this->_an_customerPaymentProfileId; $sql = "insert into {$tableName} values ('', '$customerId', '$acPI', '$acPI', '3')"; $writeconnection->query($sql); $sql = "insert into {$tableName} (magCID, anCID, anOID, anObjectType) values ('$customerId', '$acPI', '$acAI', '2')"; $writeconnection->query($sql); $sql = "insert into {$tableName} (magCID, anCID, anOID, anObjectType) values ('$customerId', '$acPI', '$acPPI', '1')"; $writeconnection->query($sql); I have verified using Firebug and FirePHP that the SQL queries are syntactically correct and no errors are returned. The odd thing here is that I have checked the database, and the autoincrement value is incremented on every run of the code. However, no rows are inserted in the database. I have verified this by adding a die(); statement directly after the first write. Any ideas why this would be occuring? The relative portion of the config.xml is this: <config> <global> <models> <authorizecim> <class>CPAP_AuthorizeCim_Model</class> </authorizecim> <authorizecim_mysql4> <class>CPAP_AuthorizeCim_Model_Mysql4</class> <entities> <anlink> <table>authorizecim_magento_id_link</table> </anlink> </entities> <entities> <antypes> <table>authorizecim_magento_types</table> </antypes> </entities> </authorizecim_mysql4> </models> <resources> <authorizecim_setup> <setup> <module>CPAP_AuthorizeCim</module> <class>CPAP_AuthorizeCim_Model_Resource_Mysql4_Setup</class> </setup> <connection> <use>core_setup</use> </connection> </authorizecim_setup> <authorizecim_write> <connection> <use>core_write</use> </connection> </authorizecim_write> <authorizecim_read> <connection> <use>core_read</use> </connection> </authorizecim_read> </resources> </global> </config>

  • How to created filtered reports in WPF?

    - by Michael Goyote
    Creating reports in WPF. I have two related tables. Table A-Customer: CustomerID(PK) Names Phone Number Customer Num Table B-Items: Products Price CustomerID I want to be able to generate a report like this: CustomerA Items Price Item A 10 Item B 10 Item C 10 --------------- Total 30 So this is what I have done: <Window x:Class="ReportViewerWPF.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:rv="clr-namespace:Microsoft.Reporting.WinForms; assembly=Microsoft.ReportViewer.WinForms" Title="Customer Report" Height="300" Width="400"> <Grid> <WindowsFormsHost Name="windowsFormsHost1"> <rv:ReportViewer x:Name="reportViewer1"/> </WindowsFormsHost> </Grid> Then I created a dataset and loaded the two tables, followed by a report wizard (dragged all the available fields and dropped them to the Values pane). The code behind the WPF window is this: public partial class CustomerReport : Window { public CustomerReport() { InitializeComponent(); _reportViewer.Load += ReportViewer_Load; } private bool _isReportViewerLoaded; private void ReportViewer_Load(object sender, EventArgs e) { if (!_isReportViewerLoaded) { Microsoft.Reporting.WinForms.ReportDataSource reportDataSource1 = new Microsoft.Reporting.WinForms.ReportDataSource(); HM2DataSet dataset = new HM2DataSet(); dataset.BeginInit(); reportDataSource1.Name = "DataSet";//This is the dataset name reportDataSource1.Value = dataset.CustomerTable; this.reportViewer1.LocalReport.DataSources.Add(reportDataSource1); this.reportViewer1.LocalReport.ReportPath = "../../Report3.rdlc"; dataset.EndInit(); HM2DataSetTableAdapters.CustomerTableAdapter funcTableAdapter = new HM2DataSetTableAdapters.CustomerTableAdapter(); funcTableAdapter.ClearBeforeFill = true; funcTableAdapter.Fill(dataset.CustomerTable); _reportViewer.RefreshReport(); _isReportViewerLoaded = true; } } As you might have guessed this loaded this list of customer with items and price: Customer Items Price Customer A Items A 10 Customer A Items B 10 Customer B Items D 10 Customer B Items C 10 How can I fine-tune this report to look like the one above, where the user can filter the customer he wants displayed on the report? Thanks in advance for the help. I would have preferred to use LINQ whenever filtering data

  • multi-thread in MS Access, async processing

    - by LanguaFlash
    I know that title sounds crazy but here is my situation. After a certain user event I need to update a couple tables that are "unrelated" to what the user is currently doing. Currently this takes a couple seconds to execute and causes the user a certain amount of frustration. Is there a way to perform my update in a second process or in a manner that doesn't "freeze" the UI of my app while it is processing? Thanks

  • OpenVPN IPv6 over IPv4 tunnel

    - by user66779
    Today I installed OpenVPN 2.3rc2 on both my windows 7 client machine and centos 6 server. This new version of OpenVPN provides full compatibility for IPv6. The Problem: I am currently able to connect to the server (through the IPv4 tunnel) and ping the IPv6 address which is assigned to my client and I can also ping the tun0 interface on the server. However, I cannot browse to any IPv6 websites. My vps provider has given me this: 2607:f840:0044:0022:0000:0000:0000:0000/64 is routed to this server (2607:f840:0:3f:0:0:0:eda). This is ifconfig after setup with OpenVPN running: eth0 Link encap:Ethernet HWaddr 00:16:3E:12:77:54 inet addr:208.111.39.160 Bcast:208.111.39.255 Mask:255.255.255.0 inet6 addr: 2607:f740:0:3f::eda/64 Scope:Global inet6 addr: fe80::216:3eff:fe12:7754/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2317253 errors:0 dropped:7263 overruns:0 frame:0 TX packets:1977414 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1696120096 (1.5 GiB) TX bytes:1735352992 (1.6 GiB) Interrupt:29 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.8.0.1 P-t-P:10.8.0.2 Mask:255.255.255.255 inet6 addr: 2607:f740:44:22::1/64 Scope:Global UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:739567 errors:0 dropped:0 overruns:0 frame:0 TX packets:1218240 errors:0 dropped:1542 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:46512557 (44.3 MiB) TX bytes:1559930874 (1.4 GiB) So OpenVPN is sucessfully creating a tun0 interface and assigning clients IPv6 addresses using 2607:f840:44:22::/64. The first client to connect is getting 2607:f840:44:22::1000 and the second 2607:f840:44:22::1001, and so on... plus 1 each time. After connecting as the first client, I can ping from my windows client machine 2607:f740:44:22::1 and 2607:f740:44:22::1000. However, I have no access to IPv6 websites. I believe the problem is that the tun0 IPv6 addressees are not being forwarded to the eth0 interface. This is the firewall running on the server: #!/bin/sh # # iptables configuration script # # Flush all current rules from iptables # iptables -F iptables -t nat -F # # Allow SSH connections on tcp port 22 # iptables -A INPUT -i eth0 -p tcp --dport 22 -j ACCEPT iptables -A OUTPUT -o eth0 -p tcp --sport 22 -j ACCEPT # # Set access for localhost # iptables -A INPUT -i lo -j ACCEPT # # Accept connections on 1195 for vpn access from client # iptables -A INPUT -i eth0 -p udp --dport 1195 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -p udp --sport 1195 -m state --state ESTABLISHED -j ACCEPT # # Apply forwarding for OpenVPN Tunneling # iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -s 10.8.0.0/24 -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 209.111.39.160 iptables -A FORWARD -j REJECT # # Enable forwarding # echo 1 > /proc/sys/net/ipv4/ip_forward # # Set default policies for INPUT, FORWARD and OUTPUT chains # iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT # # IPv6 # IP6TABLES=/sbin/ip6tables $IP6TABLES -F INPUT $IP6TABLES -F FORWARD $IP6TABLES -F OUTPUT echo -n "1" >/proc/sys/net/ipv6/conf/all/forwarding echo -n "1" >/proc/sys/net/ipv6/conf/all/proxy_ndp echo -n "0" >/proc/sys/net/ipv6/conf/all/autoconf echo -n "0" >/proc/sys/net/ipv6/conf/all/accept_ra $IP6TABLES -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT $IP6TABLES -A INPUT -i eth0 -p tcp --dport 22 -j ACCEPT $IP6TABLES -A INPUT -i eth0 -p icmpv6 -j ACCEPT $IP6TABLES -P INPUT ACCEPT $IP6TABLES -P FORWARD ACCEPT $IP6TABLES -P OUTPUT ACCEPT Server.conf: server-ipv6 2607:f840:44:22::/64 server 10.8.0.0 255.255.255.0 port 1195 proto udp dev tun ca ca.crt cert server.crt key server.key dh dh2048.pem ifconfig-pool-persist ipp.txt push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 208.67.222.222" push "dhcp-option DNS 208.67.220.220" keepalive 10 60 tls-auth ta.key 0 cipher AES-256-CBC comp-lzo user nobody group nobody persist-key persist-tun status openvpn-status.log log-append openvpn.log verb 5 Client.conf: client dev tun nobind keepalive 10 60 hand-window 15 remote 209.111.39.160 1195 udp persist-key persist-tun ca ca.crt key client1.key cert client1.crt remote-cert-tls server tls-auth ta.key 1 comp-lzo verb 3 cipher AES-256-CBC I'm not sure where I am going wrong, it could be the firewall, or something missing from server or client.conf. This version of OpenVPN was only released yesterday, and there's little info on the internet about how to setup an IPv6 over IPv4 vpn tunnel. I've read the manual for this new version of OpenVPN (parts pertaining to IPv6) and it provides very little info too. Thanks for any help.
