  • User will input some filter criteria -- how can I turn it into a regular expression for String.match

    - by envinyater
    I have a program where the user will enter a string such as PropertyA = "abc_*" and I need to have the asterisk match any character. In my code, I'm grabbing the property value and replacing PropertyA with the actual value. For instance, it could be abc_123. I also pull out the equality symbol into a variable. It should be able to cover this type of criteria PropertyB = 'cba' PropertyC != '*-this' valueFromHeader is the lefthand side and value is the righthand side. if (equality.equals("=")) { result = valueFromHeader.matches(value); } else if (equality.equals("!=")) { result = !valueFromHeader.matches(value); } EDIT: The existing code had this type of replacement for regular expressions final String ESC = "\\$1"; final String NON_ALPHA = "([^A-Za-z0-9@])"; final String WILD = "*"; final String WILD_RE_TEMP = "@"; final String WILD_RE = ".*"; value = value.replace(WILD, WILD_RE_TEMP); value = value.replaceAll(NON_ALPHA,ESC); value = value.replace(WILD_RE_TEMP, WILD_RE); It doesn't like the underscore here... abcSite_123 != abcSite_123 (evaluates to true) abcSite_123$1.matches("abcSite$1123") It doesn't like the underscore...

  • MediaWiki: how to hide users from the user list?

    - by Dave Everitt
    I've set up Mediawiki 1.15.1 for a client who has added two users by mistake. They now want to hide these users from the user list. It seems this is done via the $wgGroupPermissions array with $wgGroupPermissions['suppress']['hideuser'] = true;, but it isn't at all clear what entry this needs for the hiding to work, or whether a new group ('hidden' or whatever) has to be created first with $wgAddGroups['bureaucrat'] = true;. For now, I've added the two users to be hidden to the 'Oversight' group which explains 'Block a username, hiding it from the public (hideuser)', but they still appear on the Special:ListUsers page. At a loss as to how the MediWiki arrays alter options displayed in the interface, so far I've added this to LocalSettings.php: $wgGroupPermissions['suppress']['hideuser'] = true; $wgAddGroups['supress'] = true; Or - since they haven't actually added anything to the wiki - could they simply be removed from the MySQL users table - although MediaWiki warns against this? Has anyone else done this successfully? Update - this is a hole in MediaWiki admin (although there are workarounds). See this thread on MediaWIki Users and the note to the reply below.

  • How would I go about letting a user add and associate a comma separated list of categories while add

    - by Throlkim
    I've been struggling for quite a while to get this feature working: I want my user to be able to select categories when uploading a photograph, but additionally be able to specify a comma-separated list of categories to create/find and associate with the photograph. I've had this working by using an attr_accessor :new_categories on the photographs model, but having that there without the column existing breaks both Paperclip and Exifr. Obviously, image upload and EXIF data retrieval are pretty important for a photography website, but not being able to add categories while uploading a photograph is a pain in the arse. Methods I've tried so far: Using attr_accessor to add a field for new_categories. Breaks gems. Using an Ajax sub-form to add categories. Formtastic can't handle it. Adding a column for new_categories to the photograph model. It works, but it's horrific. I haven't tried using a nested form, but I'd need to intercept it and stop it from processing it as normal. Here's an example of what I'm trying to accomplish: http://imgur.com/rD0PC.png And the function I use to associate the categories: def process_new_categories unless self.new_categories.nil? for title in self.new_categories.split(",") self.categories << Category.find_or_create_by_title(title.strip.capitalize) end end end Has anyone got any ideas as to how to do this?

  • how to emulate thread local storage at user space in C++ ?

    - by vprajan
    I am working on a mobile platform over Nucleus RTOS. It uses Nucleus Threading system but it doesn't have support for explicit thread local storage i.e, TlsAlloc, TlsSetValue, TlsGetValue, TlsFree APIs. The platform doesn't have user space pthreads as well. I found that __thread storage modifier is present in most of the C++ compilers. But i don't know how to make it work for my kind of usage. How does __thread keyword can be mapped with explicit thread local storage? I read many articles but nothing is so clear for giving me the following basic information will __thread variable different for each thread ? How to write to that and read from it ? does each thread has exactly one copy of the variable ? following is the pthread based implementation: pthread_key_t m_key; struct Data : Noncopyable { Data(T* value, void* owner) : value(value), owner(owner) {} int* value; }; inline ThreadSpecific() { int error = pthread_key_create(&m_key, destroy); if (error) CRASH(); } inline ~ThreadSpecific() { pthread_key_delete(m_key); // Does not invoke destructor functions. } inline T* get() { Data* data = static_cast<Data*>(pthread_getspecific(m_key)); return data ? data->value : 0; } inline void set(T* ptr) { ASSERT(!get()); pthread_setspecific(m_key, new Data(ptr, this)); } How to make the above code use __thread way to set & get specific value ? where/when does the create & delete happen? If this is not possible, how to write custom pthread_setspecific, pthread_getspecific kind of APIs. I tried using a C++ global map and index it uniquely for each thread and retrieved data from it. But it didn't work well.

  • What's the best way to send user-inputted text via AJAX to Google App Engine?

    - by Cuga
    I'm developing in Google App Engine (python sdk) and I want to use jQuery to send an Ajax request to store an answer to a question. What is the best way to send this data to the server? Currently I have: function storeItem(question_id) { var answerInputControl = ".input_answer_"+question_id; var answer_text = $(answerInputControl).text(); $.ajax({ type: "POST", url: "store_answer.html", data: "question="+question_id, success: function(responseText){ alert("Retrieved: " + responseText); } }); } This takes a question Id and provides it to the server via the query string. But on the server-side, I'm unable to access the content of the answer control which I want to store. Without Ajax, I'm able to perform this operation with the following: class StoreAnswers(webapp.RequestHandler): def post(self): question_id = self.request.get("question_id") answer_text = self.request.get("input_answer" + question_id) But when doing this call through Ajax, my answer_text is empty. Do I need to send the contents of this control as part of the data with the Ajax request? Do I add the control itself to the query string? Its contents? Does it matter that the content might be a few hundred characters long? Is this the most-recommended practice? If sending it as a query string, what's the best way to escape the content so that a malicious user doesn't harm the system?

  • How to limit a user to entering 10 keywords or less using PHP & MySQL?

    - by G4TV
    I'm trying to limit my users to entering at least 10 keywords and was wondering how would I be able to do this using PHP & MySQL with my current Keyword script? Here is the add keywords PHP MySQL code. if (isset($_POST['tag']) && trim($_POST['tag'])!=='') { $tags = explode(",", $_POST['tag']); for ($x = 0; $x < count($tags); $x++){ $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $query1 = "INSERT INTO tags (tag) VALUES ('" . mysqli_real_escape_string($mysqli, strtolower(htmlentities(trim(strip_tags($tags[$x]))))) . "')"; if (!mysqli_query($mysqli, $query1)) { print mysqli_error($mysqli); return; } $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"SELECT id FROM tags WHERE tag='" . mysqli_real_escape_string($mysqli, strtolower(htmlentities(trim(strip_tags($tags[$x]))))) . "'"); if (!$dbc) { print mysqli_error($mysqli); } else { while($row = mysqli_fetch_array($dbc)){ $id = $row["id"]; } } $query2 = "INSERT INTO question_tags (tag_id, question_id, user_id, date_created) VALUES ('$id', '$question', '$user', NOW())"; if (!mysqli_query($mysqli, $query2)) { print mysqli_error($mysqli); return; } } }

  • Can I save & store a user's submission in a way that proves that the data has not been altered, and that the timestamp is accurate?

    - by jt0dd
    There are many situations where the validity of the timestamp attached to a certain post (submission of information) might be invaluable for the post owner's legal usage. I'm not looking for a service to achieve this, as requested in this great question, but rather a method for the achievement of such a service. For the legal (in most any law system) authentication of text content and its submission time, the owner of the content would need to prove: that the timestamp itself has not been altered and was accurate to begin with. that the text content linked to the timestamp had not been altered I'd like to know how to achieve this via programming (not a language-specific solution, but rather the methodology behind the solution). Can a timestamp be validated to being accurate to the time that the content was really submitted? Can data be stored in a form that it can be read, but not written to, in a proven way? In other words, can I save & store a user's submission in a way that proves that the data has not been altered, and that the timestamp is accurate? I can't think of any programming method that would make this possible, but I am not the most experienced programmer out there. Based on MidnightLightning's answer to the question I cited, this sort of thing is being done. Clarification: I'm looking for a method (hashing, encryption, etc) that would allow an average guy like me to achieve the desired effect through programming. I'm interested in this subject for the purpose of Defensive Publication. I'd like to learn a method that allows an every-day programmer to pick up his computer, write a program, pass information through it, and say: I created this text at this moment in time, and I can prove it. This means the information should be protected from the programmer who writes the code as well. Perhaps a 3rd party API would be required. I'm ok with that.

  • I just received a complaint from a user of the website I maintain. Should I do anything?

    - by Chris
    I was sent sent a large wall of text from a user of the website I maintain at my job. They are clearly upset for having to deal with a horribly outdated web application that has not seen any serious updates in over 6+ years. No refactoring has been done, the code quality is terrible, the security unchecked, policy compliances ignored, in addition to being ugly and frankly embarrassing. Keep in mind this is a small business but the website is used by hundreds daily. I'm one of two programmers there, and I've been working there for two years. This person says they are about my age (22) and understand technology (but can't use proper grammar). The complaint mentioned awkward pages and actions on the website, but they don't even have a clue as to the depth of the flaws in this website. Now, I would love to honestly tell them that there's a lot wrong with this company and that this application was built when we were in high school. And that while it's not my fault that the website is terrible, I'm the one in position to fix it. But on the other hand, I could just say nothing and ignore it. Would doing this publicly have any advantage to future employees (showing integrity) or would it just be a completely pointless mistake? Odds are, even if I respond only that one person will ever read it. Regardless, I'm probably just going to ignore it and continue starting my project to refactor the website.

  • How do I apply an arcball (using quaternions) along with mouse events, to allow the user to look around the screen using the o3d webgl framework?

    - by Chris
    How do I apply an arcball (using quaternions) along with mouse events, to allow the user to look around the screen using the o3d webgl framework? This sample (http://code.google.com/p/o3d/source/browse/trunk/samples_webgl/o3d-webgl-samples/simpleviewer/simpleviewer.html?r=215) uses the arcball for rotating the transform of an "object", but rather than apply this to a transform, I would like to apply the rotation to the camera's target, to create a first person style ability to look around the scene, as if the camera is inside the centre of the arcball instead of rotating from the outside. The code that is used in this sample is var rotationQuat = g_aball.drag([e.x, e.y]); var rot_mat = g_quaternions.quaternionToRotation(rotationQuat); g_thisRot = g_math.matrix4.mul(g_lastRot, rot_mat); The code that I am using which doesn't work var rotationQuat = g_aball.drag([e.x, e.y]); var rot_mat = g_quaternions.quaternionToRotation(rotationQuat); g_thisRot = g_math.matrix4.mul(g_lastRot, rot_mat); var cameraRotationMatrix4 = g_math.matrix4.lookAt(g_eye, g_target, [g_up[0], g_up[1] * -1, g_up[2]]); var cameraRotation = g_math.matrix4.setUpper3x3(cameraRotationMatrix4,g_thisRot); g_target = g_math.addVector(cameraRotation, g_target); where am I going wrong? Thanks

  • Launching firefox on remote server causes local firefox to start instead

    - by terdon
    Right, this is strange. I am connecting from my laptop (LMDE) to a remote host (SUSE linux enterprise) using ssh -X. I want to launch a firefox instance running on the remote server so I can have access to webpages on a private network. User@RemoteMachine $ which -a firefox /usr/bin/firefox User@RemoteMachine $ /usr/bin/firefox --version Mozilla Firefox 2.0.0.2, Copyright (c) 1998 - 2007 mozilla.org User@LocalMachine $ which -a firefox /usr/bin/firefox User@LocalMachine $ /usr/bin/firefox --version Mozilla Firefox 14.0.1 Now, if firefox is not running on the local machine, everything goes as expected and executing firefox on the remote machine causes a firefox (v 2.0) window running on the remote machine to show up. However, if firefox is running on the local machine a second window of firefox 14.0.1 running on the local machine appears. I have checked top in both machines. In the 2nd case, a firefox process briefely appears on the remote machine and then disappears when the local version of firefox is launched. My questions are the following: What gives? How/why can firefox connect to its existing instance on the local machine? The remote machine appears to have access to the local machine. It, in fact, appears to have the right to execute programs on my local machine. Am I missing something or is this just weird? Is this not a security risk?

  • Fedora 16 can connect to samba share using smbclient but not in nautilus 3.2.1

    - by Nathan Jones
    I have a machine running Ubuntu 11.10 Server acting as a Samba server to share my home directory. Everything works fine on my Windows 7 machine, but on my Fedora 16 laptop, if I use Nautilus to try to access the share using smb://192.168.0.8/nathan in the location bar, it just has the loading cursor and does nothing. It never shows any errors, nothing. Using smbclient works just fine, but I'd like to get it working in Nautilus.

  • How to setup Calendar permissions for group to group

    - by Sorean
    I've been scouring the internet and so far have only been able to find examples of how to grant calendar permissions from one user to another using the Add-MailboxFolderPermission command. This is great and it was okay for when they only had a handful of users. But going forward it's not realistic to have to set individual calendar permissions for all calendars for each new user. Layout of security groups already created. Each group has a few people assigned to it. Techs Managers Admin What I am trying to accomplish is set it up so that anyone that belongs to the Managers group can view the calendars of the Tech group. Admins can view and edit the Tech group. I've found an example of adding just the security group name but I get an error of: [PS] C:\Windows\system32add-MailboxFolderPermission -Identity Techs:\Calendar -User "Admin" -AccessRights Owner The user "Admin" is either not valid SMTP address, or there is no matching information. + CategoryInfo : NotSpecified: (0:Int32) [Add-MailboxFolderPermission], InvalidExternalUserIdException + FullyQualifiedErrorId : 39352699,Microsoft.Exchange.Management.StoreTasks.AddMailboxFolderPermission Am I creating groups wrong? Am I using the wrong commands? Any guidance would be greatly appreciated.

  • Adding network share as the system account breaks Win7 backup to network

    - by ChrisBenn
    (On Win7 Ultimate x64 SP1) So I've been using Win7 backup to \192.168.0.100\Backup\main-desktop\ for awhile without issue. Yesterday I tried to setup crashplan to synchronize my dropbox folder and a network share. I then found out that crashplan, as it runs under the system account, can't see my user mapped drives. So I created a startup script net use O: \192.168.0.100\Documents /USER:192.168.0.100\username password and set it to run, on startup, after the network interface is up, as the system account. (the username & password are the same for the net use script above, the locally logged in user, and the explicit username/password entered in windows backup). I woke up this morning to find error flags from the windows backup and get "Network location cannot be used" (0x800704B3). If I disable the startup task & reboot then windows backup works fine. I'm not sure why having a mapped drive for another user is killing windows backup (same server, different folder). I can work around the issue by using another program to synchronize the two folders, but I'm completely in the dark as to why this happens (and it's 100% repeatable). Uninstalling the crashplan client doesn't change anything - it's the net use run under the system account that breaks win7 backup (to a network location).

  • Large mailbox in Outlook 2007 takes ages to index

    In our company each user has a single mailbox and all email they have ever sent/received is in that mailbox. We don't do archiving to PST and we thought that was the way forward. The problem we now have is if someone switches to another PC for the day and opens Outlook, it has to download all emails first to that PC (cached mode) but even then when they try to search for something, Outlook says items are still being indexed. One user has over 100,000 items to be indexed and it's been saying that for about a week! As a temporary workaround I have turned off instant searching which allows them to search for anything, but it takes time to filter through, and Outlook doesn't exactly indicate if it's still searching for something, so in most cases the user thinks the search isn't working when really it is and it's just taking time to populate the results. I need a solution that allows the mailbox to be indexed really quickly if the user has to login to another PC. Are we best using Online Mode instead of Cached Mode or is there another way around this? Thanks in advance.

  • Custom authentication method for GDM

    - by FMC
    I am trying to find a way of authenticating users on public computers through GDM, but I have a few things to be taken in account. The users do not have a login/password, they only thing they are given is a string. This string is unique and will allow us to identify them. You can see this string as a login without a password. The users must be present in a remote database The users must have the rights to login on the computer they are on at that time. A remote database would check if a booking on the computer had been set for that time by that user. Or if no booking had been made, allow to login. A default user id/home/gid has to be set to the user once logged in I have found ways to deal with most of those requirements, but not altogether. PAM looks nice to set up a custom way of checking if the user booked its computer. NSS MySQL looks nice to set up the environment. Would you know how to set up the environment by myself using a custom PAM module (using pam_python would be preferred)? Or any other method that could help me? Thanks in advance!

  • GNU screen multiuser mode is broken in OS X 10.6 (Snow Leopard)

    - by schustafa
    I'm using GNU screen for remote pair programming. Let's call the local account for the remote user 'pairpair'. I have the following lines in my .screenrc: multiuser on acladd pairpair I have run sudo chmod u+s /usr/bin/screen. However, when the remote user tries to connect to my screen with the command screen -r [my_account_name]/[pid_of_screen] I receive the following message: Attach attempt with bad pid(xxx) The pid listed in the error message matches the pid of the screen process run by the remote user. The remote user's screen process hangs; my screen session continues happily along after the error message disappears. I've tried using both the built-in screen (at /usr/bin/screen) and the screen available from MacPorts, but I get the same error in both cases. This worked on OS X 10.5 (Leopard). I've googled around for the error message, but most of the hits relate to some BSD bug from 2003 or so (which was fixed). Has anyone else seen this behavior? Does anyone have any idea how to make multiuser support in screen work in SL?

  • Windows 7 - How to access my documents from Windows 8 (dual boot)

    - by msbg
    I am dual booting Windows 7 and Windows 8 on two different partitions of the same drive: Win7: (C:) Win8: (D:) I am trying to get access to my Win7 user folder (C:\Users\Mason) in order to access my Win7 documents folder (C:\Users\Mason\Documents) from Windows 8. When I try to on Windows 8, I get an error message saying "You don't have permission to access this folder. Click here to permanently get access to this folder". When I click, the progress bar in Windows Explorer slowly moves to the maximum and disappears. When I try opening the folder, I get the same error message. When editing security permissions for the folder in Windows 8, Explorer freezes. I do not know how to remove the restrictions from Windows 7. I checked the Windows 8 user folder (D:\Users\Mason) and it had the group or user name: "S-1-5-21-936898901-3363470404-1273668825-1001". I tried copying and pasting it into the Win7 User Folder Permissions, but got the error "An object with the following name cannot be found". How would I access my folders?

  • samba "username map" stopped to work

    - by Kris_R
    It was time to upgrade our group server (new HDs, problems with old installation of DRBD, etc..). Going as usually for CentOS i upgraded whole system from 6.3 to 6.4 The later one came with samba 3.6 as the old one was 3.5. I transferred most of users by copying /etc/password, /etc/shadow and samba accounts with pdbedit. Homes were on nfs-drive. The translation of unix accounts to samba accounts are located in /etc/samba/smbusers. Strangely enough on some windows clients there was problem to connect to samba-shares. In one case the only thing that worked was, instead of giving windows name, to use the unix account. In another one, it was possible to mount network drive and to open it in Windows Explorer, however other applications like "Total commander" at the attempt of opening this drive gave the message "Cannot connect to z:" (sometimes at this moment user/pass were requested). The smb.conf has following entries: [global] security = user passdb backend = tdbsam username map = /etc/samba/smbusers ... [Kris] comment = Kris's Private path = /SMB/Users/Kris writeable = yes read only = no browseable = yes users = krisr printable = no security mask = 0777 force security mode = 0 directory security mask = 0777 force directory security mode = 0 force create mode = 0775 force directory mode = 6775 The smbusers: # Unix_name = SMB_name1 SMB_name2 ... krisr = Kris Of course testparm runs without any errors. I was used from samba 3.5 to outputs of form Mapped user Kris to krisr. Nothing like this happens now. Just message check_sam_security: Couldn't find user Kris in passdb. I read on web that some guys had problem with 3.6 and security = ADS, but these were not helpful for me. I'm seriously thinking about downgrading back to samba 3.5 but before this step I wanted to ask if somebody knows the solution of these problems. p.s. i've asked this question at serverfault but no answer came. Maybe I have more luck with this forum. Sorry for duplicate if any of you reads both.

  • Advanced Linux file permission question (ownership change during write operation)

    - by Kent
    By default the umask is 0022: usera@cmp$ touch somefile; ls -l total 0 -rw-r--r-- 1 usera usera 0 2009-09-22 22:30 somefile The directory /home/shared/ is meant for shared files and should be owned by root and the shared group. Files created here by usern (any user) are automatically owned by the shared group. There is a cron-job taking care of changing owning user and owning group (of any moved files) once per day: usera@cmp$ cat /etc/cron.daily/sharedscript #!/bin/bash chown -R root:shared /home/shared/ chmod -R 770 /home/shared/ I was writing a really large file to the shared directory. It had me (usera) as owning user and the shared group as group owner. During the write operation the cron job was run, and I still had no problem completing the write process. You see. I thought this would happen: I am writing the file. The file permissions and ownership data for the file looks like this: -rw-r--r-- usera shared The cron job kicks in! The chown line is processed and now the file is owned by the root user and the shared group. As the owning group only has read access to the file I get a file write error! Boom! End of story. Why did the operation succeed? A link to some kind of reference documentation to back up the reason would be very welcome (as I could use it to study more details).

  • Why does notepad crash on desktop files in the save-as dialog?

    - by deepc
    Here's a puzzling problem - maybe somebody has an idea. Right now I am out of ideas. On Win7 64bit, the following crashes Notepad: On Desktop, right click, select "New | Text Document". This creates "New Text Document.txt". Right click on that file, select "Edit". This opens notepad with the empty file. Select "File | Save as": Notepad crashes and Win7 reports that "Notepad has stopped working". Now, move the file to c:\temp and repeat steps 2 and 3: no crash this time and the save-as dialog appears normally. I can create similar steps for the "open" dialog. Things I have tried: Safe mode - does not work, same problem Create a new user and try again logged in as that user - no crash Name file differently, or create elsewhere and then move to desktop - same problem Use Wordpad instead - same problem Review shell extensions with ShellExView - nothing extraordinary here Stare at the event log entries for each of the crashes. Does not enlighten me. At time of crash look at the process explorer stack view. Hangs at a function "TaskDialog". sfc.exe /scannow repaired some files but the problem persists. This is how the event log entries look like: Log Name: Application Source: Application Error Date: 14.12.2010 00:33:48 Event ID: 1000 Task Category: (100) Level: Error Keywords: Classic User: N/A Description: Faulting application name: NOTEPAD.EXE, version: 6.1.7600.16385, time stamp: 0x4a5bc9b3 Faulting module name: COMCTL32.dll, version: 6.10.7600.16661, time stamp: 0x4c6f6e4b Exception code: 0xc000041d Fault offset: 0x00000000000db770 Faulting process id: 0x198 Faulting application start time: 0x01cb9b1e140ab92a Faulting application path: C:\Windows\system32\NOTEPAD.EXE Faulting module path: C:\Windows\WinSxS\amd64_microsoft.windows.common-controls_6595b64144ccf1df_6.0.7600.16661_none_fa62ad231704eab7\COMCTL32.dll What else should I try, short of dumping my user and starting over with a new profile? Thanks...

  • fcgiwrap listening to a unix socket file: how to change file permissions

    - by user36520
    I have a web server (nginx) and a CGI application (gitweb) that is ran with fcgiwrap to enable Fast CGI access to it. I want the Fast CGI protocol to take place over a unix socket file. To start the fcgiwrap daemon, I run: setuidgid git fcgiwrap -s "unix:$PWD/fastcgi.sock" (this is a daemontools daemon) The problem is that my web server runs as the user www-data and not the user git. And fcgiwrap creates the socket fastcgi.sock with user git, group git and read only fort the non owner. Thus, nginc with the user www-data can't access the socket. Apparently, fcgiwrap is not able to select permissions of unix socket files. And this is quite annoying. Moreover, if I manage to have the socket file exists before I run fcgiwrap (which is quite difficult given I did not find any shell command to create a socket file), it quits with the following error: Failed to bind: Address already in use The only solution I found is to start the server the following way: rm -f fastcgi.sock # Ensure that the socket doesn't already exists (sleep 5; chgrp www-data fastcgi.sock; chmod g+w fastcgi.sock) & exec setuidgid git fcgiwrap -s "unix:$PWD/fastcgi.sock" Which is far from the most elegant solution. Can you think of anything better ? Thanks

  • XP Pro freezes on welcome screen

    - by Peter B
    I have a problem that sounds much the same as http://superuser.com/questions/83101/how-to-diagnose-a-freeze-on-startup-in-windows-xp About every 2nd or 3rd boot, XP-Pro freezes on the Welcome page (the one showing the user name icons). The mouse moves the cursor OK, but clicking on an icon does nothing, and neither does any keystroke. If you press too many keys there is a beep and after that the mouse won't move the cursor anymore. The work-around is always to reboot into Safe mode and request a CHKDSK /R After this, the next boot is fine. There are no related entries in the Event log when the problem occurs. The only two entries are: "Microsoft (R) Windows (R) 5.01. 2600 Service Pack 3 Multiprocessor Free." "The Event log service was started." Update 1: Many thanks for that but I found no problems with any diagnostics I have run. But, I have managed to locate, and code round, the source of the problem - which is with whatever processing goes on behind the XP Welcome (as opposed to "classic") login screen. Unfortunately, having classic login means you don't get the useful Fast User Switching (FUS) login/switch mode. So, to retain this, my fix is: Add a Windows shutdown script (using gpedit.msc) to force "classic" mode for the first logon after next XP startup, by running: reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v LogonType /t REG_DWORD /d 0 /f Add a Scheduled Task to run at User Logon that enables Welcome screen (and hence FUS) by running the same command with 1 instead of 0 after the /d flag. The task is run as a privileged user (who can run "reg add").

  • Microsoft Word 2007 restarts the installer upon exiting on Windows XP

    - by leeand00
    A user complained that they were having issues with MS Office 2007, and that the installation / configuration dialog kept appearing. I already tried uninstalling Office 2007 and I ended up needing to use the Microsoft Fix It package to uninstall it, since using the control panel failed. I close Microsoft Word. The Installer for Microsoft Office inexplicably opens. I then get a dialog that says I need to reboot. So I restart... Start Microsoft Word, Word starts up, and everything appears to be fine. I close word, and nothing much happens this is on the administrator account. I think everything is fixed so I call the user over to come try their account out. We login as the user, and the user tries to open a document in Word. The Configuration Progress Window reappears. It runs...and then Word appears. I close it and it appears to work, no window. I open it again and the Configuration Progress window appears yet again... Then Word opens up again, if I exit out and open up again I get the same Configuration Progress window. I have no idea what is causing the Configuration Progress Window to come up.. Update: I attempted to install two updates: Update for Microsoft Office Outlook 2007 Junk Email Filter (KB2687400) Update for the 2007 Microsoft Office System (KB967642) Both of these updates failed. Update: I attempted to install KB967642 manually and it failed.
