• Python not Working in Vim

  - by jdg

  I have a new install of VIM from the automatic windows installer: gvim73_46.exe I have Python 2.7 (32 bit) installed. If I open gvim, and type: :set python? I get E518: Unknown option. If I try typing: :python 'hello' Vim crashes. What could be wrong? Here are the contents of :version in case they are helpful, although python is installed, and it is using Python 2.7. I also checked, and C:\Windows\System32\python27.dll is where it should be... I am really lost here. Does anyone have any ideas as to what is going wrong?

• Windows 7 comments field missing when browsing network

  - by Toymangenie

  I have just purchased three Windows 7 Professional Dell 64-bit PCs for testing prior to upgrading our company’s 120+ PCs from Windows XP Professional. The setup is a standard domain with a Windows Server 2003 32-bit server. We name each PC XP1 to XP150 so that when users join or leave, I don’t have to rename the PC. We use the Description field to allocate the user’s name to each PC. We also have a share set up on each PC using the user’s name. When I browse the network using Windows Explorer in XP, I get a useful display. The left pane showing the PC number and the right pane showing NAME and COMMENTS So, for example I would see: XP01 Fred Bloggs (Each PC on a new row.) The right pane is my main tool for administering the network. I can easily see the PC number and the name of the user. However, in Windows 7, this seems to have been thrown out of the window and replaced with fields that I do not need and in my case always display the same info. "Name", "Category", "Workgroup", "Network Location" In my case the Name column gives the PC number (XP10) etc and all three other columns display identical useless information. So I can’t see who is using XP10. When I am in “help desk” mode, I would naturally ask the user’s name and use my remote desktop client to view their screen. The user isn’t aware of their PC name, so I am finding it impossible to match the user name with a PC number. Any ideas how to overcome this "by design" change to Windows 7?

• Using ACK to list directories

  - by KPthunder

  I have a directory listing as follows (given by ls -la): total 8 drwxr-xr-x 6 <user> <group> 204 Oct 18 12:13 . drwxr-xr-x 7 <user> <group> 238 Oct 18 11:29 .. drwxr-xr-x 14 <user> <group> 476 Oct 18 12:31 .git -rw-r--r-- 1 <user> <group> 601 Oct 18 12:03 index.html drwxr-xr-x 2 <user> <group> 68 Oct 18 12:13 test drwxr-xr-x 2 <user> <group> 68 Oct 18 12:13 test2 Running ack . -f prints out the files in the directory: index.html How can I get ack to print out the directories in the directory? I want to ignore the .git directory (which I understand is default behavior for ack). On that note, how can I ignore certain directories? I am using ack 1.9.6 on Mac OSX 10.8.2.

• NTFS 'Owner' missing when accessing hard disk from external USB adapter

  - by trismarck

  I have a hard drive with Windows XP SP3 installed on it. When the drive is connected through the standard SATA connector inside the laptop, everything works as expected. However when I remove the drive from the laptop and connect the drive to the external USB adapter, almost all files / folders lose the 'Owner' field contents. I was wondering why could that be. I've tried two USB adapters and this happens on each. I could take the ownership of all of the files, but this would overwrite the Owner value (the Owner value that is present when the drive is accessed through standard SATA connector in the laptop). //edit: if the hard drive is used through the USB adapter, I can't access most of the files, at least until I take ownership of the files (/folders). This is how it looks like: HDD inside USB adapter: HDD inside laptop: (note the Owner column) //edit: some of the files on the first screenshot have Owner field filled up. That's because I took the ownership of those files / folders to be able to access the files on the hard drive. //edit2: also, if the hard drive is connected through USB adapter and if I've took the ownership of some files by the 'ddd' user, then if i login as a different user (lets say 'eee' user), the owner field is _still_ empty: ddd user: eee user: eee user can't access the 'ddd' folder. Both users have Administrator priviledges.

• Who should I run mysql as, on a personal computer?

  - by user664833

  I just installed mysql via homebrew (with brew install mysql, on Mac OS X Mountain Lion - recently installed from scratch). Following the installation, there is a "caveats" section with options around further necessary actions to take: ==> Caveats Set up databases to run AS YOUR USER ACCOUNT with: unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp To set up base tables in another folder, or use a different user to run mysqld, view the help for mysqld_install_db: mysql_install_db --help and view the MySQL documentation: * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html To run as, for instance, user "mysql", you may need to `sudo`: sudo mysql_install_db ...options... Start mysqld manually with: mysql.server start Note: if this fails, you probably forgot to run the first two steps up above A "/etc/my.cnf" from another install may interfere with a Homebrew-built server starting up correctly. To connect: mysql -uroot To launch on startup: * if this is your first install: mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist * if this is an upgrade and you already have the homebrew.mxcl.mysql.plist loaded: launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist You may also need to edit the plist to use the correct "UserName". On previous versions of Mac OS X I ran mysql as mysql user, but now I am confronted by the idea of running it as myself. I am the only one who uses this computer (which happens to be my laptop), and I do programming for work and for pleasure. What are the pros & cons, or best practices, around choosing whether to run mysql AS YOUR USER ACCOUNT or as mysql or something else still?

• How to Impersonate a user for a file copy over the network when dns or netbios is not available

  - by Scott Chamberlain

  I have ComputerA on DomainA running as userA needing to copy a very large file to ComputerB on WorkgroupB which has the ip of 192.168.10.2 to a windows share that only userB has write access to. There is no netbios or dns resolving so the computer must be refrenced by IP I first I tried AppDomain.CurrentDomain.SetPrincipalPolicy(System.Security.Principal.PrincipalPolicy.WindowsPrincipal); WindowsIdentity UserB = new WindowsIdentity("192.168.10.2\\UserB", "PasswordB"); //Execption WindowsImpersonationContext contex = UserB.Impersonate() File.Copy(@"d:\bigfile", @"\\192.168.10.2\bifgile"); contex.Undo(); but I get a System.Security.SecurityException "The name provided is not a properly formed account name." So I tried AppDomain.CurrentDomain.SetPrincipalPolicy(System.Security.Principal.PrincipalPolicy.WindowsPrincipal); WindowsIdentity webinfinty = new WindowsIdentity("ComputerB\\UserB", "PasswordB"); //Execption But I get "Logon failure: unknown user name or bad password." error instead. so then I tried IntPtr token; bool succeded = LogonUser("UserB", "192.168.10.2", "PasswordB", LogonTypes.Network, LogonProviders.Default, out token); if (!succeded) { throw new Win32Exception(Marshal.GetLastWin32Error()); } WindowsImpersonationContext contex = WindowsIdentity.Impersonate(token); (...) [DllImport("advapi32.dll", SetLastError = true)] static extern bool LogonUser( string principal, string authority, string password, LogonTypes logonType, LogonProviders logonProvider, out IntPtr token); but LogonUser returns false with the win32 error "Logon failure: unknown user name or bad password" I know my username and password are fine, I have logged on to computerB as that user.

• Use Java exceptions internally for REST API user errors?

  - by user303396

  We have a REST API that works great. We're refactoring and deciding how to internally handle errors by the users of our API. For example the user needs to specify the "movie" url parameter which should take the value of "1984", "Crash", or "Avatar". First we check to see if it has a valid value. What would be the best approach if the movie parameter is invalid? return null from one of the internal methods and check for the null in the main API call method throw an exception from the internal method and catch exceptions in the main API method I think it would make our code more readable and elegant to use exceptions. However, we're reluctant because we'd be potentially throwing many exceptions because of user API input errors, our code could be perfect. This doesn't seem to be the proper use of exceptions. If there are heavy performance penalties with exceptions, which would make sense with stack traces needing to be collected, etc., then we're unnecessarily spending resources when all we need to do is tell the user the parameter is wrong. These are REST API methods, so we're not propogating the exceptions to the users of the API, nor would we want to even if possible. So what's the best practice here? Use ugly nulls or use java's exception mechanism?

• Is it possible to handle User Defined Exception using JAX WS Dispatch API ?

  - by snowflake

  Hello, I'm performing dynamic webservices call using following code snippet: JAXBContext jc = getJAXBContext(requestClass, responseClass, jaxbContextExtraClasses); Dispatch<Object> dispatch = service.createDispatch(portQName, jc, Service.Mode.PAYLOAD); Object requestValue = getRequestValue(requestClass, pOrderedParameters); JAXBElement<?> request = new JAXBElement(new QName(serviceQNameStr, pOperationName), requestValue.getClass(), null, requestValue); Object tmpResponse = dispatch.invoke(request); Invocation works perfectly, except if I add a user defined exception on the service (a basic UserException extends java.lang.Exception). First I get: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are <{http://my.namespace/}myMethod,<{http://my.namespace/}myResponse Then I added the UserException_Exception JAX-WS generated type to my JAXB Context, and then get: Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions java.lang.StackTraceElement does not have a no-arg default constructor. this problem is related to the following location: at java.lang.StackTraceElement at public java.lang.StackTraceElement[] java.lang.Throwable.getStackTrace() at java.lang.Throwable at java.lang.Exception Only solution available I found are: dispatch directly a Soap message and handle Soap fault directly (this is the way Jboss JAX-WS implementation performs a standard JAX-WS call using services interfaces). This is not an available solution for me, I want to use a high level implementation (the more I get close to Soap message the less dynamic my code can be) usage of JAXBRIContext.ANNOTATION_READER, which is implementation specific and not an available solution for me, in order to annotate annotates java.lang.Exception as @XmlTransient The service with a user defined exception performs well using the JAX-WS generated standard client stubs and using a tool such Soap UI. Problem occurs in deserialization of the message when I have no user defined exception artifact in the JAXB context, and during invocation when I add those non JAXB compatible artifacts in the JAXB context. I'm usign Jboss WS webservice stack within Jboss 4.2.3.GA Any elegant solution to this problem is welcomed !

• Tabular (X)HTML forms

  - by detly

  I have a set of items that can be in various states. I want to allow a user to use an (X)HTML form to change the state, and easily view the state of a group of objects ...so to this end, I'd like a layout like: | item1 | radio button for state 1 | radio for state 2 | ... | [update button] | | item2 | radio button for state 1 | radio for state 2 | ... | [update button] | etc. I prefer the radio buttons to list boxes so that it's easy for a user to visually scan for things in a certain state. It seemed like perfectly tabular data to me. The only problem is, you can't have forms inside a table that cross table cells (ie. <tr> <form> <td> ... is invalid). I thought, "hey, I could have one giant form wrapping a table, and make the [update button] value contain the IDs for each row!" Turns out certain versions of IE send ALL THE SUBMIT BUTTON VALUES on any single form. So I thought perhaps to to lay it out with <div>s and place the forms inside a single <td>. But then they break a line on each <div>. So I fixed their width and made them float: left. But then they wrap inside the table cells if the table row is wider than the page, and the radio controls don't line up with the headings. Is it possible to lay this out as I intend? The XHTML below shows the intended structure. Observe what happens if you resize the browser window below the width of the table (ideally, the name would break or the table would show a scroll bar). <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head><title>Test</title> <style type="text/css"> .state-select, .thing-state-name, .update { float: left; width: 8em; } .state-select { text-align: center; } </style> </head> <body> <table> <thead> <tr> <th class="thing-name-header">Thing</th> <th> <div class="thing-state-name">Present</div> <div class="thing-state-name">Absent</div> <div class="thing-state-name">Haven't looked</div> </th> </tr> </thead> <tbody> <tr> <td>Apple</td> <td> <form action="something" method="post"> <input type="hidden" name="id" value="1" /> <div class="state-select"><input type="radio" name="presence" value="present" checked="checked" /></div> <div class="state-select"><input type="radio" name="presence" value="absent" /></div> <div class="state-select"><input type="radio" name="presence" value="unknown" /></div> <div class="update"><input type="submit" value="Update" /></div> </form> </td></tr> <tr> <td>Orange</td> <td> <form action="something" method="post"> <input type="hidden" name="id" value="2" /> <div class="state-select"><input type="radio" name="presence" value="present" /></div> <div class="state-select"><input type="radio" name="presence" value="absent" checked="checked" /></div> <div class="state-select"><input type="radio" name="presence" value="unknown" /></div> <div class="update"><input type="submit" value="Update" /></div> </form> </td></tr> <tr> <td>David Bowie</td> <td> <form action="something" method="post"> <input type="hidden" name="id" value="3" /> <div class="state-select"><input type="radio" name="presence" value="present" /></div> <div class="state-select"><input type="radio" name="presence" value="absent" /></div> <div class="state-select"><input type="radio" name="presence" value="unknown" checked="checked" /></div> <div class="update"><input type="submit" value="Update" /></div> </form> </td></tr> </tbody> </table> </body> </html>

• How does one decrypt a PDF with an owner password, but no user password?

  - by Tony Meyer

  Although the PDF specification is available from Adobe, it's not exactly the simplest document to read through. PDF allows documents to be encrypted so that either a user password and/or an owner password is required to do various things with the document (display, print, etc). A common use is to lock a PDF so that end users can read it without entering any password, but a password is required to do anything else. I'm trying to parse PDFs that are locked in this way (to get the same privileges as you would get opening them in any reader). Using an empty string as the user password doesn't work, but it seems (section 3.5.2 of the spec) that there has to be a user password to create the hash for the admin password. What I would like is either an explanation of how to do this, or any code that I can read (ideally Python, C, or C++, but anything readable will do) that does this so that I can understand what I'm meant to be doing. Standalone code, rather than reading through (e.g.) the gsview source, would be best.

Besides I find no method to wait for the page in the webrat API. Can someone give some tips on how to proceed with debugging this?

• Have an unprivileged non-account user ssh into another box?

  - by Daniel Quinn

  I know how to get a user to ssh into another box with a key: ssh -l targetuser -i path/to/key targethost But what about non-account users like apache? As this user doesn't have a home directory to which it can write a .ssh directory, the whole thing keeps failing with: $ sudo -u apache ssh -o StrictHostKeyChecking=no -l targetuser -i path/to/key targethost Could not create directory '/var/www/.ssh'. Warning: Permanently added '<hostname>' (RSA) to the list of known hosts. Permission denied (publickey). I've tried variations using -o UserKnownHostsFile=/dev/null and setting $HOME to /dev/null and none of these have done the trick. I understand that sudo could probably fix this for me, but I'm trying to avoid having to require a manual server config since this code will be deployed on a number of different environments. Any ideas? Here's a few examples of what I've tried that don't work: $ sudo -u apache export HOME=path/to/apache/writable/dir/ ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -l deploy -i path/to/key targethost Eventually, I'll be using this solution to run rsync as the apache user.

• My framework will utilise other frameworks, but I'd like this to be transparent to the end-user

  - by d11wtq

  I'm building a framework, which aims to provide a new development environment for the user, but I need to use things like RegexKit and almost certainly some other established frameworks in order to do this. Any functionality exposed from such frameworks would be abstracted through classes and methods in my own framework for maintenance reasons (allowing me to change my mind on which dependencies I want). In an ideal world I just want to ship a single .framework. However I'm aware that unlike with standard bundles and applications it is not possibile to embed a framework inside the framework bundle. Do I have any other option other than to tell the end user that they must also install RegexKit and any other dependencies? I have a feeling this lessens the appeal value of the easy to use embedded framework I'd envisaged building. Right now I'm feeling like I have some limited options: Force the user to install the dependencies. Write my own classes that provide the same functionality -- ugh! If at all possible, try to statically link the third party frameworks (is this possible??) My end-product is ideally a single .framework bundle that uses @rpath and so can be installed in the system or simply bundled with the app that uses it.

• Incorporating Devise Authentication into an already existing user structure?

  - by Kevin

  I have a fully functional authentication system with a user table that has over fifty columns. It's simple but it does hash encryption with salt, uses email instead of usernames, and has two separate kinds of users with an admin as well. I'm looking to incorporate Devise authentication into my application to beef up the extra parts like email validation, forgetting passwords, remember me tokens, etc... I just wanted to see if anyone has any advice or problems they've encountered when incorporating Devise into an already existing user structure. The essential fields in my user model are: t.string :first_name, :null => false t.string :last_name, :null => false t.string :email, :null => false t.string :hashed_password t.string :salt t.boolean :is_userA, :default => false t.boolean :is_userB, :default => false t.boolean :is_admin, :default => false t.boolean :active, :default => true t.timestamps For reference sake, here's the Devise fields from the migration: t.database_authenticatable :null => false t.confirmable t.recoverable t.rememberable t.trackable That eventually turn into these actual fields in the schema: t.string "email", :default => "", :null => false t.string "encrypted_password", :limit => 128, :default => "", :null => false t.string "password_salt", :default => "", :null => false t.string "confirmation_token" t.datetime "confirmed_at" t.datetime "confirmation_sent_at" t.string "reset_password_token" t.string "remember_token" t.datetime "remember_created_at" t.integer "sign_in_count", :default => 0 t.datetime "current_sign_in_at" t.datetime "last_sign_in_at" t.string "current_sign_in_ip" t.string "last_sign_in_ip" t.datetime "created_at" t.datetime "updated_at" What do you guys recommend? Do I just remove email, hashed_password, and salt from my migration and put in the 5 Devise migration fields and everything will be OK or do I need to do something else?

• Use ini/appconfig file or sql server file to store user config?

  - by h2g2java

  I know that the preference for INI or appconfig XML is their human readability. Let's say user preferences stored for my app are hierarchical and numbers about a thousand items and it would be really confusing for a user to edit an INI to change things anyway. I have always been using a combination of INI with appconfig. I am leaning towards using sql server db file, now. Every time the user changes a preference while using the app, it would be stored into the db file - that's my line of thought. I am also thinking that such a config db file could move around with the app too, just like an INI. Before I do that, any advice 1. If there are any disadvantages against using a db file over INI or appconfig. 2. If a shop uses mysql or oracle, do you think your colleagues would lift up their pro-mysql or pro-oracle eyebrow questioning why you would use sql server technology in a mysql or oracle shop? I mean, I am just using it like an INI file or app.config anyway, right?

• plugin instancing

  - by Hailwood

  Hi guys, I am making a jquery tagging plugin. I have an issue that, When there is multiple instances of the plugin on the page, if you click on any <ul> that the plugin has been called on it will put focus on the <input /> in the last <ul> that the plugin has been called on.

• .NET MissingMethodException occuring on one of thousands of end-user machines -- any insight?

  - by Yoooder

  This issue has me baffled, it's affecting a single user (to my knowledge) and hasn't been reproduced by us... The user is receiving a MissingMethodException, our trace file indicates it's occuring after we create a new instance of a component, when we're calling an Initialize/Setup method in preparation to have it do work (InitializeWorkerByArgument in the example) The Method specified by the error is an interface method, which a base class implements and classes derived from the base class can override as-needed The user has the latest release of our application All the provided code is shipped within a single assembly Here's a very distilled version of the component: class Widget : UserControl { public void DoSomething(string argument) { InitializeWorkerByArgument(argument); this.Worker.DoWork(); } private void InitializeWorkerByArgument(string argument) { switch (argument) { case "SomeArgument": this.Worker = new SomeWidgetWorker(); break; } // The issue I'm tracking down would have occured during "new SomeWidgetWorker()" // and would have resulted in a missing method exception stating that // method "DoWork" could not be found. this.Worker.DoWorkComplete += new EventHandler(Worker_DoWorkComplete); } private IWidgetWorker Worker { get; set; } void Worker_DoWorkComplete(object sender, EventArgs e) { MessageBox.Show("All done"); } } interface IWidgetWorker { void DoWork(); event EventHandler DoWorkComplete; } abstract class BaseWorker : IWidgetWorker { virtual public void DoWork() { System.Threading.Thread.Sleep(1000); RaiseDoWorkComplete(this, null); } internal void RaiseDoWorkComplete(object sender, EventArgs e) { if (DoWorkComplete != null) { DoWorkComplete(this, null); } } public event EventHandler DoWorkComplete; } class SomeWidgetWorker : BaseWorker { public override void DoWork() { System.Threading.Thread.Sleep(2000); RaiseDoWorkComplete(this, null); } }

• How can I send rich emails using the user's mail client ?

  - by Brann

  I need my .net program to send rich emails (usually containing table data, around 20 columns x 10 rows) using the user's mail infrastructure, allowing him to review/edit the mail before sending it, and storing the mail in his 'sent items' folder. mailto: seems the obvious choice, but unfortunately, it doesn't support neither attachments nor html bodies. It seems some clients support some extra features (e.g. Outlook 97 used to support a &Attach tag, but this is not the case for more recent versions). I could use mailto and try to format the text body to look nice (using tabs, etc), but this isn't really elegant and wouldn't support huge data. using automation seems a very huge task, as I would need to automate dozens of clients (4 or 5 versions of outlook, lotusnotes, thunderbid, etc.) ... This would be a huge task and it's not really my core business ... I could send emails through code and write my own mail form to let the user edit the mail, but this would have a lot of drawbacks : the user would need to manually configure the mail server settings he wouldn't have access to his contact directory the mail wouldn't be sent in his sent items folder This seems a quite common issue, but I haven't found any satisfying solution yet ; does someone knows of a library supporting this (ie containing automation logic for most mainstream email clients?). Or an alternative to mailto ?

• How do I deliver mail for wildcard addresses to a particular user/alias/program?

  - by David M

  I need to configure sendmail so that mail delivered for wildcard addresses is accepted for delivery and then delivered to a user, alias, or directly to a script. I can rewrite the envelope/headers any number of ways, but I don't know how to accept the wildcard address when it's provided in RCPT TO: Everything I've tried so far winds up with a 550 user unknown error. So here's a specific example: I want to be able to handle any address that consists of a series of digits followed by a dot followed by a word, then pipe that to a script. If the headers get rewritten, that's OK, but I need the envelope to contain the actual Delivered-To address. Here's the sort of SMTP session I need: 220 blah.foo.com ESMTP server ready; Thu, 22 Apr 2010 20:41:08 -0700 (PDT) HELO blort.foo.com 250 blah.foo.com Hello blort.foo.com [10.1.2.3], pleased to meet you MAIL FROM: <[email protected]> 250 2.1.0 <[email protected]>... Sender ok RCPT TO: <[email protected]> 250 2.1.5 <[email protected]>... Recipient ok I tried some stuff with regex maps, but I never got past 550 user unknown.

• Algorithm for assigning a unique series of bits for each user?

  - by Mark

  The problem seems simple at first: just assign an id and represent that in binary. The issue arises because the user is capable of changing as many 0 bits to a 1 bit. To clarify, the hash could go from 0011 to 0111 or 1111 but never 1010. Each bit has an equal chance of being changed and is independent of other changes. What would you have to store in order to go from hash - user assuming a low percentage of bit tampering by the user? I also assume failure in some cases so the correct solution should have an acceptable error rate. I would an estimate the maximum number of bits tampered with would be about 30% of the total set. I guess the acceptable error rate would depend on the number of hashes needed and the number of bits being set per hash. I'm worried with enough manipulation the id can not be reconstructed from the hash. The question I am asking I guess is what safe guards or unique positioning systems can I use to ensure this happens.

• Forcing user to new page in php. (PHP newbie)

  - by JohnC

  Hello I'm a newbie web programmer. My background is writing Windows applications with sql. I'm putting together my 1st data entry screens in Php. I have a search form that links to a form that displays records in a grid. On each row of the grid I have a delete url to allow the user to remove a record. This links to a form delete.php (which calls the sql to remove the record). Ideally I would like to automatically take the user back to the search form rather than forcing the user to click on a link to do so. I have used ob_start with the header to do this elsewhere but cannot get it to work on this page. Is there another way to do it? (Using php 5 as part of LAMP) file delete.php <?php $id = $_GET['recordID']; //ob_start(); require_once('connections/local.php'); mysql_select_db($database_local, $local); mysql_query("DELETE FROM user_access WHERE id = {$id}") or die(mysql_error()); echo("Record ".$id." deleted"); echo("<br>"); //header("location:http://localhost/search7.htm); //ob_flush(); echo("<a href=\"http://localhost/search7.htm\">Search for Members</a>"); ?>

• How to make NSIS create a file in an %APPDATA% of another user?

  - by SCO

  I wrote an NSIS installer script for postgresql 9.1. The installer works properly, but after the reboot, the service is not started (right after the install, the database started properly though) I guess this is because the postgres service user has no pgpass.conf file in its %APPDATA%. As far as I understand my install script, the pgpass.conf file is added to the %APPDATA% of the user running the installer (an administrator account in my case). This will not help. I tried the following, to add the pgpass.conf to all users, bt I guess this adds it to a kind of wildcard, not to the %APPDATA% of each user : SetShellVarContext "all" SetOutPath "$APPDATA\postgresql" File config\pgpass.conf SetShellVarContext "current" SetOutPath "$APPDATA\postgresql" File config\pgpass.conf I couldn't find the macro name for c:/Users/postgres in the documentation. This could be a way to achieve it. But with WindowsXP, 7, I wish I need a portable way to address the /Users directory. I wish I could use something like SetShellVarContext "postgres", and then have NSIS write the pgpass.conf file in c:\Users\postgres\AppData\postgresql. Is there a way to do this ? Thnk you !

• Getting the number of posts a user has by the number of rows returned?

  - by transparent

  So I have a question. I have chatting/IM website that I am working on and I was making a user profile page. I wanted to show how many posts that user had. Another issue I had earlier was that when I called a certain value it would return a 'Resource #1' type string. But I got that working by using $totalposts=mysql_query("SELECT * FROM `posts` WHERE Username='" . $username . "'"); $totalposts = mysql_fetch_row($totalposts); $totalposts = $totalposts[0]; But that just returns the last postID of the most recent post. I thought that mysql_num_rows would work. But this code returns an error (example with numbers): 29: $totalposts=mysql_query("SELECT * FROM `posts` WHERE Username='" . $username . "'"); 30: $totalposts = mysql_num_rows($totalposts); 31: $totalposts =mysql_fetch_row($totalposts); 32: $totalposts = $totalposts[0]; That returns this error: Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/a9091503/public_html/im/user.php on line 31 Thanks guys. :) I hope you can figure this out. :D
