• how to remove an entry from system tray?

  - by altvali

  I've searched for an answer to this one and I haven't found one yet. How do i remove a single item from Windows' System tray? I'm targeting Windows XP. Edit: This is not about preventing items from starting up. I want the program to keep running, I just need another script/program to remove the first one's entry from system tray. Second Edit: One approach that I can think of is to try to hide the intended app by modifying registry keys. On several test machines I've found some registry entries that match the System tray information at HKEY_USERS\something-that-looks-like S-1-5-21-682003330-1563985344-725345543-1003\Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify with BalloonTip, IconStream and PastIconsStream containing systray information. The important one is IconStream. On other machines, these are found at hkey_classes_root/local/setting/software/microsoft/windows/currentversion/TrayNotify I'm quite sure there's no danger in changing those specific registries, but I don't know how to write code for that. Can anyone help me with the code and with confirming if this has the desired effect of hiding the systray icon for an active program?

• How do I get netcat to accept connections from outside the LAN?

  - by Chris

  I'm using netcat as a backend to shovel data back and forth for a program I'm making. I tested my program on the local network, and once it worked I thought it would be a matter of simply forwarding a port from my router to have my program work over the internet. Alas! This seems not to be the case. If I start netcat listening on port 6666 with: nc -vv -l -p 6666, then go to 127.0.0.1:6666 in a browser, as expected I see a HTTP GET request come through netcat (and my browser sits waiting in vain). If I go to my.external.ip.address:6666, however, nothing comes through at all and the browser displays 'could not connect to my.external.ip.address:6666'. I know that the port is correctly forwarded, as www.canyouseeme.org says port 6666 is open (and when netcat is not listening, that its closed). If I run netcat with -g my.adslmodem's.local.address to set the gateway address, I get the same behavior. Am I using this command line option correctly? Any insight as to what I'm doing wrong?

• Password Cracking Windows Accounts

  - by Kevin

  At work we have laptops with encrypted harddrives. Most developers here (on occasion I have been guilty of it too) leave their laptops in hibernate mode when they take them home at night. Obviously, Windows (i.e. there is a program running in the background which does it for windows) must have a method to unencrypt the data on the drive, or it wouldn't be able to access it. That being said, I always thought that leaving a windows machine on in hibernate mode in a non-secure place (not at work on a lock) is a security threat, because someone could take the machine, leave it running, hack the windows accounts and use it to encrypt the data and steal the information. When I got to thinking about how I would go about breaking into the windows system without restarting it, I couldn't figure out if it was possible. I know it is possible to write a program to crack windows passwords once you have access to the appropriate file(s). But is it possible to execute a program from a locked Windows system that would do this? I don't know of a way to do it, but I am not a Windows expert. If so, is there a way to prevent it? I don't want to expose security vulnerabilities about how to do it, so I would ask that someone wouldn't post the necessary steps in details, but if someone could say something like "Yes, it's possible the USB drive allows arbitrary execution," that would be great! EDIT: The idea being with the encryption is that you can't reboot the system, because once you do, the disk encryption on the system requires a login before being able to start windows. With the machine being in hibernate, the system owner has already bypassed the encryption for the attacker, leaving windows as the only line of defense to protect the data.

• What is the difference between Startup programs in windows and the same programs being started manually

  - by sup

  I am no Windows guy, but I am trying to get a seamless integration of Windows program through Virtual Box Windows guest onto my Ubuntu machine. I more or less followed this tutorial: https://nowhere.dk/articles/running-windows-applications-natively-with-seamlessrdp Basically I start up Windows in Virtual Box and then I try to launch an application (on Ubuntu host) like this: rdesktop -A -s "c:\Program Files\ThinLinc\WTSTools\seamlessrdpshell.exe notepad.exe" 192.168.123.103:3389 -u user -p password That just gives me full Windows desktop that I do not want. However, when I run (on the Windows guest) "c:\Program Files\ThinLinc\WTSTools\seamlessrdpshell.exe" "notepad" The command above works and I get just the window I want. Now, so I thought I would put this command into startup folder of the Windows machine and everything would be fine. But it says "Unable to set up the virtual channel". (by googling, I nailed it to this file: https://sourceforge.net/p/rdesktop/code/1686/tree/seamlessrdp/trunk/ServerExe/vchannel.c - the warning is triggered (by main.c in the same directory) when function vchannel_open() returns something that C interprets as yes for if condition). I have no idea why it works when I launch this command manually via a bat file and not when I put it to startup programs. Any ideas?

• Software to capture 3d geometry?

  - by user712092

  Programs I found I found these programs to capture OpenGL 3D scene : 3D Ripper, OpenGL and D3D geometry capture, there are some solved problems with 3D Ripper GLIntercept captures OpenGL function calls OpenGL Extractor captures 3d geometry; should work as plugin for GLIntercept another tool to capture OpenGL 3D data EDIT: There is also HijackGL which changes how a scene is rendered so it probably can be used to capture geometry; it is backed up by a academic paper; it is just just a nice program, not related to what I want i think (or it would might be hard to change it to be for what I want, because it would require programming). 3D Ripper captures geometry, textures and shaders. OpenGL Extractor captures just geometry ... General questions about such programs What is Your experience with these programs? Which of these programs would You recommmend? Do You know other such programs? Were there any problems with them, or are there problems with them in general? Are there programs which work best overall, or is it specific to certain 3d applications? What I need to do? I am looking to program which can capture 3d geometry for study purposes. And also for a program to capture 3D animation (frames of 3d animation). I tried only 3D Ripper because application I try to capture data from is on Direct 3D. 3D Ripper works with at least Direct 3D 9, this application has Direct 3D 6. Are there applications which work with older version of Direct 3D? Thank You very much. :) (I was verbose in link names because I want them to be indexed better by search engines.)

• Why does Windows 7 always automatically change the input or keyboard language?

  - by B-Ball

  I am wondering why Windows 7 always automatically changes my input or keyboard language. I've a notebook with an integrated QWERTY keyboard English (United States). Traveling, I use that one but, additionally, I've my own as well as a much better keyboard at home which is a QWERTZ keyboard German (Germany). Thus, being at home, I'd like to use my QWERTZ keyboard. Unfortunately, Windows 7 does not play along at this one. Every time, I start up my notebook, it is usually set to English (United States) but that's not the problem. In case, I'd use my notebook QWERTY keyboard English (United States), that's fine. However, if I start up my notebook and I'd like to use my QWERTZ keyboard German (Germany), I usually press ALT + Left Shift in order to switch from English (United States) to German (Germany) and Windows 7 switches the input language but only for the program that is currently open. If my input language is set to German (Germany) and I, e.g., open NotePad, Windows 7 automatically switches my input language to English (United States). This is very annoying since I've to change the input or keyboard language to German (Germany) every time I open up a new program. Why doesn't Windows 7 stay with one input language if I changed it manually by pressing ALT + Left Shift? Why doesn't the manual change of the input or keyboard language apply for the whole Windows 7? Why does it only affect the currently opened program? Since I've two keyboards with two different layouts, I seriously need to have both of the keyboards languages installed. I tried both of the below settings in order to find a solution for my problem. Currently, I am using the first option, two input languages. First option: two input languages: Second option: two keyboard languages:

• Setup.exe called from a batch file crashes with error 0x0000006

  - by Alex

  We're going to be installing some new software on pretty much all of our computers and I'm trying to setup a GPO to do it. We're running a Windows Server 2008 R2 domain controller and all of our machines are Windows 7. The GPO calls the following script which sits on a network share on our file server. The script it self calls an executable that sits on another network share on another server. The executable will imediatelly crash with an error 0x0000006. The event log just says this: Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Setup.exe because of this error. Here's the script (which is stored on \\WIN2K8R2-F-01\Remote Applications): @ECHO OFF IF DEFINED ProgramFiles(x86) ( ECHO DEBUG: 64-bit platform SET _path="C:\Program Files (x86)\Canam" ) ELSE ( ECHO DEBUG: 32-bit platform SET _path="C:\Program Files\Canam" ) IF NOT EXIST %_path% ( ECHO DEBUG: Folder does not exist PUSHD \\WIN2K8R2-PSA-01\PSA Data\Client START "" "Setup.exe" "/q" POPD ) ELSE ( ECHO DEBUG: Folder exists ) Running the script manually as administrator also results in the same error. Setting up a shortcut with the same target and parameters works perfectly. Manually calling the executable also works. Not sure if it matters, but the installer is based on dotNETInstaller. I don't know what version though. I'd appreciate any suggestions on fixing this. Thanks in advance! UPDATE I highly doubt this matters, but the network share that the script is hosted in is a shared drive, while the network share the script references for the executable is a shared folder. Also, both shares have Domain Computers listed with full access for the sharing and security tabs. And PUSHD works without wrapping the path in quotes.

• How can Standard User change file associations in Windows 2000?

  - by Gary M. Mugford

  One of my clients is still running Win2K server with a host of Win2K workstations. And no net admin, due to the downturn of the economy over the years. I'm sort of helping out. Out of my depth, but I am a loyal foot soldier. A problem I encounter rather too often is a user double-clicks on a file in Explorer and then either gets no action, or the wrong program to run. It's a case of a missing or out-of-date file association. The current cure is to temporarily upgrade the user from Standard to Power, do the FA switch and then change back. As Winnie would whine, 'Oh, bother!' At any rate, I thought I'd ask here. Is there a method/program to run without the rigamarole FROM the Standard Users account on the workstation to edit/add a file association? I assume the program route would involve RunAs. I 'believe' most of the workstations run the RunAs service, but I could be wrong. I understand that's required, if there is to be a solution. Any help accepted with thanks. GM NOTE: Seems wassociate from http://www.xs4all.nl/~wstudios/Associate/index.html can resolve the issue.

• permanent NAS-mount in Ubuntu - wrong fs type, bad option, bad superblock

  - by Emil

  My network drive shows up in the file browser, just like my external usb-harddrive. Moving, running and editing files works. Hovering over it shows smb://lacie-2big/nasdisk . BUT, when I want to save a file, the drive doesn't come up as an option. All I can see is my other places, including my usb-harddrive. I am a complete newbie but I am GUESSING that it has something to do with the mount not being a "real" mount but just a shortcut to the smb location. So I ran the tutorial at https://wiki.ubuntu.com/MountWindowsSharesPermanently about how to "mount a network drive permanently". edited my fstab to //LaCie-2big/nasdisk /media/nasmount cifs guest,uid=1000,iocharset=utf8,codepage=unicode,unicode 0 0 and running sudo mount -a gave me the following error: mount: wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program) In some cases useful info is found in syslog - try dmesg | tail or so Now thats a very helpful error message, BUT, before I go any further, I'd be really thankful if one of you could tell me if I'm even in the right ballpark, or if my actual need: to be able to download files (ie torrents) directly to the drive, can be possible as it is already. Question: How to fix "wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program" when running mount -a

• OpenVPN, install a TAP adapter

  - by GolezTrol

  When I try to connect to my work VPN using OpenVPN, the connection fails with the message: All TAP-Win32 adapters on this system are currently in use. Many sources suggest to look in Control Panel\Network and Internet\Network Connections an enable the TAP adapter, but when I look there, there is none. Now I've run addtap.bat which is provided with OpenVPN, but I still don't get to see any TAP adapter, and logging in in VPN still fails. The output of addtap.bat is C:\Windows\system32>"C:\Program Files (x86)\OpenVPN\bin\tapinstall.exe" install "C:\Program Files (x86)\OpenVPN\driver\OemWin2k.inf" tap0801 Device node created. Install is complete when drivers are updated... Updating drivers for tap0801 from C:\Program Files (x86)\OpenVPN\driver\OemWin2k .inf. Drivers updated successfully. I've Run As Administrator both the setup of OpenVPN and addtap.bat. I've run deltapall.bat to remove any (maybe hidden) adapters. It said it removed three of them, after which I ran addtap.bat again to try to create another one. I also run OpenVPN itself as administrator. What's wrong? Running Windows 7 Home Premium on a HP Pavilion dv7 4050ed. It has worked before, but I recently had to reinstall my laptop, for which I used the restore disks I created when I just got it. Everything else seems to work fine. == UPDATE == The TAP adapter is found in Device Manager, but apparently it is disabled because it is incompatible with Windows 7 64bit. I've deïnstalled OpenVPNGui, downloaded a version that should be 64bit compatible, and installed that. Still no cigar. Then I found a tip to install OpenVPN (version 9) after installing OpenVPNGui, because that installs OpenVPN version 8. Now I got a v9 TAP driver in Device Manager, but it still doesn't work and shows up in device manager with an exclamation mark, and not at all in my network devices.

• Pre-startup segmentation fault with ptrace

  I have somehow managed to mangle my computer so that any time I attempt to use something that uses ptrace to trace another process (eg strace, gdb), I get an immediate segmentation fault. For example: # strace /bin/true execve("/bin/true", ["/bin/true"], [/* 27 vars */]) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ or with gdb: # gdb /bin/true GNU gdb Fedora (6.8-27.el5) Copyright (C) 2008 Free Software Foundation, Inc.

• Orphan IBM JVM process

  Hi people, I have this issue about orphan IBM JVM process being created in the process tree: For example: C:\Program Files\IBM\WebSphere\AppServer\bin>wsadmin -lang jython -f "C:\Hello.py" Hello.py has the simple implementation: import time i = 0 while (1): i = i + 1 print "Hello World " + str(i) time.sleep(3.0) My machine has such JVM information: C:\Program Files\WebSphere\java\bin>java -verbose:sizes -version -Xmca32K RAM class segment increment -Xmco128K ROM class segment increment -Xmns0K initial new space size -Xmnx0K maximum new space size -Xms4M initial memory size -Xmos4M initial old space size -Xmox1624995K maximum old space size -Xmx1624995K memory maximum -Xmr16K remembered set size -Xlp4K large page size available large page sizes: 4K 4M -Xmso256K operating system thread stack size -Xiss2K java thread stack initial size -Xssi16K java thread stack increment -Xss256K java thread stack maximum size java version "1.6.0" Java(TM) SE Runtime Environment (build pwi3260sr6ifix-20091015_01(SR6+152211+155930+156106)) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Windows Server 2003 x86-32 jvmwi3260sr6-20091001_43491 (JIT enabled, AOT enabled) J9VM - 20091001_043491 JIT - r9_20090902_1330ifx1 GC - 20090817_AA) JCL - 20091006_01 While the program is running, I tried to kill it and subsequently I found an orphan IBM JVM process in the process tree.

• How to set CA cert file for LDAP backend server in smbpasswd configuration

  - by hayalci

  I am having a problem with smbpasswd, an LDAP backend server and SSL/TLS certificates. The client machine that I run smbpasswd on is a Debian Etch machine, and the Ldap server is Sun DS running on Solaris. All the following occurs on the client. When I disable SSL, by setting "ldap ssl = no" in smb.conf, the smbpasswd program works without errors. When I set "ldap ssl = start tls", the following messages are printed by smbpasswd and there is a long timeout period before any password is asked by it Failed to issue the StartTLS instruction: Connect error Connection to LDAP server failed for the 1 try! ..... long delay ..... New SMB password: Retype new SMB password: Failed to issue the StartTLS instruction: Connect error Connection to LDAP server failed for the 1 try! smbpasswd: /tmp/buildd/openldap2-2.1.30/libraries/liblber/io.c:702: ber_get_next: Assertion `0' failed. Aborted I conducted some tests with "ldapsearch -ZZ". It was not working at first, but after I added the TLS_CACERT line to /etc/ldap/ldap.conf, /etc/libnss-ldap.conf and /etc/pam_ldap.conf, it started working. So relevant TLS sections in all those files are: ssl start_tls tls_checkpeer no tls_cacertfile /path/to/ca-root.pem TLS_CACERT /path/to/ca-root.pem But the smbpasswd program continued giving the error. I tried creating /etc/smbldap-tools/smbldap.conf file with following content (after consulting debian docs for smbldap-tools package) But as I see, smbpasswd comes with samba-common package and does not use the configuration for smbldap-tools utilities. verify="optional" cafile="/path/to/ca-root.pem" My question is: How can I set which SSL CA Certificate is used by smbpasswd program ?

• Why Does DreamWeaver CS5 Discriminate between File Extensions, Even After Modding Mime Types!?

  - by Sam

  Hi folks, Even After I forced DreamWeaver CS5 to allow opening of .ast extensions as a MIME type of php5, which DreamWeaver now opens and colors correctly as described here, I still have trouble figuring out why it still discriminates between the two file extensions! Symptoms: External Files & Design View I have a file foo.php which php includes other files (e.g. the php-combined css.php and js.php). Now, when opening foo.php all functions work perfectly: the external (included) php files are all recognised correctly. However, when I change foo.php foo.ast, and open it again, It does not recognise the files extensions anymore in the top bar. Also, I lose the Design / Live View functionality.** When I change foo.ast to foo.php, all works again! Anyone any clues of why there remains a a difference between one and other extension? Note1: I have added the .ast extension to these four files, next to .php: 1 C:\Users\Sam\AppData\Local\VirtualStore\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 2 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 3 C:\Users\Sam\AppData\Roaming\Adobe\Dreamweaver CS5\en_US\Configuration\Extensions.txt 4 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\Extensions.txt Note2: sometimes, even .php files do not want to show in design view or live view. Could this be caused by a corrupted installation?

• How can I both pipe and display output in Windows' command line?

  - by Bob

  I have a process I need to run within a batch file. This process produces some output. I need to both display this output to the screen and send (pipe) it to another program. The bash method uses tee: echo 'ee' | tee /dev/tty | foo Is there an equivalent for Windows? I am happy to use PowerShell if necessary. There are tee ports for Windows, but there does not appear to be an equivalent for /dev/tty, which complicates matters. The specific use-case here: I have a program (launch4j) that I need to run, displaying output to the user. At the same time, I need to be able to detect success or failure in the script. Unfortunately, this program does not set an exit code, and I cannot force it to do so. My current workaround involves piping to find, to search the output (launch4j config.xml | find "Successfully created") - however, that swallows the output I need to display. Therefore, I need some way to both display to the screen and send the ouput to a command - and this command should be able to set ERRORLEVEL (it cannot run asynchronously).

• How can I associate html/htm files with Chrome in Windows 7 64 bit?

  - by matt

  I want Chrome to open all .html files. It is currently set as my default browser, however html files open in IE9. When I go to Control Panel\Programs\Default Programs\Set Associations I see that .html and .htm files are associated with IE. When I choose to change the default program it I'm presented with a list of programs but Chrome is not one of them. I browse to, and then select the Chrome.exe (C:\Users\Matt\AppData\Local\Google\Chrome\Application\chrome.exe) but it goes right back to IE. This is the first time I've seen anything like this. I'm running Windows 7 64 bit. I never had this problem on Windows 7 32 bit. Is this because Chrome by default installs in the User directory, not the Program Files directory? How can I fix these file associations? EDIT: It's not that things are reverting back to IE after associating them with Chrome. When I browse to Chrome in the file association window, and select it, it doesn't seem to take. It doesn't show Chrome in the list of programs despite pointing to the Chrome.exe location. I really think this has something to do with the fact that it doesn't install into the Program File Directory.

• Maintaining "Portability" Between Linux and Windows 7

  - by lokheart

  I am using the following ways in my office's Windows 7 machine to maintain my "portabilibity" when disaster strikes and I need to switch computer while I have no luxury of time for reinstalling all my program to the new PC. a majority of programs I used are portable, mostly from portableapp.com, like notepad+, GIMP, even R, I extract them and store them in a folder in My document, in a structure similar to the default portableapp installation when they are installed to a thumbdrive only a few software that portable version is not available and I will install them as usual all of my working files are stored in a folder in My document I regularly backup them all using syncback, because this program can keep versioning of my backup, and the backup is stored in a portable drive. One day I need to switch my computer and the operation is relative simple for me: I just move the two folders mentioned above into the my document folder of the new PC, install those few "non-portable" program in it, and this is almost done, some minor hiccups can be solved by reinstalling the portableapp into the drive. Overall speaking it is a smooth process. I would like to maintain the same degree of "portability" in my home Linux desktop (Ubuntu or Mint, I'm still deciding), that is, if my Linux crash and I need to reinstall it again. All I need to do is the move the two folder back to the new Linux, and most of my work will be almost ready to be worked on again. But I don't know how to find a Linux-alternative of portableapps. Being a newer to Linux, can anyone tell me whether this is possible in Linux?

• Restricting Access to Application(s) on Point of Sale system

  - by BSchlinker

  I have a customer with two point of sale systems, a few workstations and a Windows 2003 SBS Server. The point of sale systems are typically running QuickBooks Point of Sale and are logged in with a user who has restricted permissions / access (via Group Policy). Occasionally, one of the managers needs to be able to run a few additional applications -- including some accounting software. I have created an additional user for this manager, allowing them to login and access the accounting software. The problem is, it can be problematic to switch users on the system, as QuickBooks takes a few minutes to close (on POSUser) and then reopen (on ManagerUser). If customers are waiting, this slows things down drastically. Since the accounting software is stored on a network drive, it would be easiest if the manager could simply double click something, authenticate against the network drive / domain controller and then the program would launch. When they close the program, the session to the network drive would be lost and the program would no longer be accessible. Is there any easy way to do this? Both users are on a domain and the system is Windows 7. I just don't want to require the user to switch back and forth. In a worst case scenario, they forget to switch back and leave the accounting software wide open.

• Using a named pipe to simulate a serial port on a VMware virtual machine (linux host and client)

  - by Dave M

  Trying to write a python program to create a simulated data stream and feed it, through a named pipe, to a VMware virtual machine. The host is running Ubuntu 11.10 and VMware player 5.0.0. The Vm is running Ubuntu netbook 10.04. I am able to get the pipe working on the local machine but I am not able to get the pipe to pass data through the virtual serial port to the programs running on the virtual machine. #!/usr/bin/python import os # # Create a named pipe that will be used as the serial port on a VMware virtual machine SerialPipe = '/tmp/gpsd2NMEA' try: os.unlink(SerialPipe) except: pass os.mkfifo(SerialPipe) # # Open the named pipe NMEApipe = os.open(SerialPipe, os.O_RDWR|os.O_NONBLOCK) # # Write a string to the named pipe NMEAtime = "235959" os.write(NMEApipe, str( '%s\n' % NMEAtime )) Test to see if the python program is working on the host machine (displays 235959 if data is passing through the pipe) $ cat /tmp/gpsd2NMEA 235959 Serial port as defined in the VMware .vmx file: serial0.present = "TRUE" serial0.startConnected = "TRUE" serial0.fileType = "pipe" serial0.fileName = "/tmp/gpsd2NMEA" serial0.pipe.endPoint = "client" serial0.autodetect = "FALSE" serial0.tryNoRxLoss = "TRUE" serial0.yieldOnMsrRead = "TRUE" Test to see if the serial port in the VM is receiving data $ cat /dev/ttyS0 or $ minicom -D /dev/ttyS0 or $ stty -F /dev/ttyS0 cs8 -parenb -cstopb 115200 $ echo < /dev/ttyS0 None of these display any data from the python program.

• Good references to know why has my computers stopped responding me

  - by Peterstone

  Hello all! I´m a windows xp user (but not for much time...) and I usually see how my computer stop of responding me. The process is this: Firsly it became totally stopped or very slow for certain periods of 5 minutes. How could I do? After that it gets stopped (Even not totally because If I click on the bar I see a blinking response in the bar botton of the program I click on. It´s could be anything related with security (like the firewall or some virus)? Computer university: I usually experience this, using Matlab (R2007a) with System Generator (its respective compatible version) My personal laptop: It´s usually works well but when stopped periods became to appears I know in not much time it will became totally stopped. I usually see how Word 2007 get stopped and after a while my windows xp gets stopped. (well I can access to the the manage task pressing ctr+alt and...). The only solution I see is to kill program by program... My petition: Please, I need good references that help me how to think in order to avoid or to manage the problems previously described. Does anyone know usefull books or articles? EDIT: Laptop: OS: XP Home Edition Version 2002 SP3 Hardware: HP Mini Intel(R)Atom(TM) CPU N270 @1,60GHz 1.99 GB RAM University Computer: OS: XP Profesional SP3 Hardware: AMD Athlon(tm) XP 1800+ 1.54 GHz, 768 MB RAM

• Search behavior of Windows 7 start menu

  - by Kevin Ivarsen

  I'm coming to Windows 7 from XP, and there are aspects of the start menu search that I like. However, there are some behaviors that seem either inconsistent or surprising to me. For example: If I type "Pa" into the search bar, Paint is the first result (under the "Programs" heading), and it is selected for me. I can just hit Enter to start the program If I have a standalone exe "testing" on my desktop, and I type "test", the program comes up as the first item (under the "Files" heading), but it is not selected for me. I have to hit down-down-down-enter to open it from the keyboard. The same appears to be true for shortcuts and folders. What classifies something as a "Program" verses a "File"? Is there any way to configure the start menu so that the first search result is always selected? As a heavy keyboard user, it seems insane for the behavior to be inconsistent, and to require so many keypresses to select the top result. Also, are there resources that document the details, limitations, and tricks of the start menu search? (For example, a "Proc Exp" search will match "Process Explorer", but not "ProcessExplorer") EDIT: I've found that instead of hitting down-down-down to select the first item (when no Programs are in the list), you can just hit tab. This helps a bit, but the inconsistent behavior still makes this search feature more awkward and frustrating than necessary.

• Difference between CurrentClockSpeed and MaxClockSpeed

  - by Ben

  Rationale this belongs on ServerFault rather than StackOverflow - I already have my program which gets the value, I am querying the value returned and what it means. I have an in-house program which audits our company PCs, and one of the things it checks is the speed of the processor. To do this, it queries the Win32_Processor WMI class and gets the value of CurrentClockSpeed. We were playing with the data today and found an anomaly with some of the speeds being reported incorrectly (for example, CurrentClockSpeed said 1.0GHz, whereas the CPU name said Intel(R) Core(TM)2 CPU T5600 @ 1.83GHz [Confirmed it is in fact 1.83GHz]). I did a bit of digging on the internet and found this blog post which might explain what is going on. My initial thought was that I could change the program to instead get the value for MaxClockSpeed instead of CurrentClockSpeed, but Microsoft's documentation doesn't clearly define what this will return. What I mean by that is will this return a value which is its actual maximum speed (say if it were overclocked) but which it would not normally be running at, or would it return what I expect, which is its maximum speed under normal (not overclocked) conditions?

• Allowing non-admin users to unstick the print spooler

  - by Reafidy

  I currently have an issue where the print que is getting stuck on a central print server (windows server 2008). Using the "Clear all documents" function does not clear it and gets stuck too. I need non-admin users to be able to clear the print cue from there work stations. I have tried using the following winforms program which I created and allows a user to stop the print spooler, delete printer files in the "C:\Windows\System32\spool\PRINTERS folder" and then start the print spooler but this functionality requires the program to be runs as an administrator, how can I allow my normal users to execute this program without giving them admin privileges? Or is there another way I can allow normal user to clear the print que on the server? Imports System.ServiceProcess Public Class Form1 Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click ClearJammedPrinter() End Sub Public Sub ClearJammedPrinter() Dim tspTimeOut As TimeSpan = New TimeSpan(0, 0, 5) Dim controllerStatus As ServiceControllerStatus = ServiceController1.Status Try If ServiceController1.Status <> ServiceProcess.ServiceControllerStatus.Stopped Then ServiceController1.Stop() End If Try ServiceController1.WaitForStatus(ServiceProcess.ServiceControllerStatus.Stopped, tspTimeOut) Catch Throw New Exception("The controller could not be stopped") End Try Dim strSpoolerFolder As String = "C:\Windows\System32\spool\PRINTERS" Dim s As String For Each s In System.IO.Directory.GetFiles(strSpoolerFolder) System.IO.File.Delete(s) Next s Catch ex As Exception MsgBox(ex.Message) Finally Try Select Case controllerStatus Case ServiceControllerStatus.Running If ServiceController1.Status <> ServiceControllerStatus.Running Then ServiceController1.Start() Case ServiceControllerStatus.Stopped If ServiceController1.Status <> ServiceControllerStatus.Stopped Then ServiceController1.Stop() End Select ServiceController1.WaitForStatus(controllerStatus, tspTimeOut) Catch MsgBox(String.Format("{0}{1}", "The print spooler service could not be returned to its original setting and is currently: ", ServiceController1.Status)) End Try End Try End Sub End Class
