  • Editing code in Visual Studio 2008 in debug mode

    - by user279521
    I am curious to know if there is a way to edit code in VS 2008 right when it has hit a breakpoint and I am walking thru the code... can I modify the code (such as the value in a variable or if my stepthrough line is about to hit an if statement ... can I modify the if statement....etc)? So far, I have to stop running VS, modify the code, then hit F5 and wait till the breakpoint is hit again.

  • Upgrade to Win7 with upgrade key and full disc

    - by Jamin
    I just ordered a retail copy of Windows 7 Professional Upgrade to finally upgrade my work computer from Vista. It's not scheduled to be delivered until Monday, though, and I was hoping to take my computer home and upgrade over the weekend. I already have a full retail (non-upgrade) disc for the same edition that I'd bought for myself, though. So can I use that disc to perform the install, and then just enter my upgrade key on Monday when it comes in? Will that make everything activate properly? Or do I need to wait till I get my actual upgrade-specific disc before I try to use my upgrade-specific key? Thanks in advance.

  • Fatal error: Incompatible file format: The encoded file has format major ID 1, whereas the Loader expects 4 in ... on line 0

    - by Eugene
    I am using Ubuntu 10.04 and for some time I had to keep a downgraded PHP 5.2 package because I need to run Zend encrypted scripts. Recently I noticed that Zend released beta version of their loader (http://forums.zend.com/viewtopic.php?f=57&t=1365&start=80#p22073) so I updated to the native PHP 5.3 package, downloaded the .so file, added this to php.ini ;zend_extension=/etc/php5/ZendOptimizer.so zend_extension=/etc/php5/ZendGuardLoader.so zend_loader.enable=1 zend_loader.disable_licensing=0 zend_loader.obfuscation_level_support=3 and restarted the server. Now I am getting this error: Fatal error: Incompatible file format: The encoded file has format major ID 1, whereas the Loader expects 4 in ... on line 0 Do you by chance know an easy fix for this? Or should I downgrade back and wait till when they release something more stable?

    - by Ala ABUDEEB
    I recently downloaded OpenSUSE OS version 11.4 from the site to use it as a server..In order to do that I downloaded the server edition that has Apache/2.2.17 and PHP5 downloaded by default.....Ok till now it is fine Now I started the Apache successfully and put a test.php file in the documentRoot directory. test.php contain only <?php phpinfo() ?> Then using my browser I typed http://localhost/test.php and here was the problem the browser didn't display what phpinfo() should display, instead it asked me whether I want to open or save test.php...which is driving me crazy.... I googled a lot but no solution THis is /etc/apache2/conf.d/php5.conf (IfModule mod_php5.c) AddHandler application/x-httpd-php .php4 AddHandler application/x-httpd-php .php5 AddHandler application/x-httpd-php .php AddHandler application/x-httpd-php-source .php4s AddHandler application/x-httpd-php-source .php5s AddHandler application/x-httpd-php-source .phps DirectoryIndex index.php4 DirectoryIndex index.php5 DirectoryIndex index.php (/IfModule)

  • heimdal kerberos in openldap issue

    - by Brian
    I think I posted this on the wrong 'sister site', so here it is. I'm having a bit of trouble getting Kerberos (Heimdal version) to work nicely with OpenLDAP. The kerberos database is being stored in LDAP itself. The KDC uses SASL EXTERNAL authentication as root to access the container ou. I created the database in LDAP fine using kadmin -l, but it won't let me use kadmin without the -l flag: root@rds0:~# kadmin -l kadmin> list * krbtgt/REALM kadmin/changepw kadmin/admin changepw/kerberos kadmin/hprop WELLKNOWN/ANONYMOUS WELLKNOWN/org.h5l.fast-cookie@WELLKNOWN:ORG.H5L default brian.empson brian.empson/admin host/rds0.example.net ldap/rds0.example.net host/localhost kadmin> exit root@rds0:~# kadmin kadmin> list * brian.empson/admin@REALM's Password: <----- With right password kadmin: kadm5_get_principals: Key table entry not found kadmin> list * brian.empson/admin@REALM's Password: <------ With wrong password kadmin: kadm5_get_principals: Already tried ENC-TS-info, looping kadmin> I can get tickets without a problem: root@rds0:~# klist Credentials cache: FILE:/tmp/krb5cc_0 Principal: brian.empson@REALM Issued Expires Principal Nov 11 14:14:40 2012 Nov 12 00:14:37 2012 krbtgt/REALM@REALM Nov 11 14:40:35 2012 Nov 12 00:14:37 2012 ldap/rds0.example.net@REALM But I can't seem to change my own password without kadmin -l: root@rds0:~# kpasswd brian.empson@REALM's Password: <---- Right password New password: Verify password -

  • Nginx rewrite rule for Zimbra

    - by Yusuf
    I'm trying to write a rewrite rule for Zimbra, which will allow me to use a hostname to access the Zimbra Desktop Web UI instead of the IP address and port. The default Zimbra URLs are like this: http://127.0.0.1:port/?at=long-encrypted-user-id http://127.0.0.1:port/zimbra/?at=long-encrypted-user-id http://127.0.0.1:port/desktop/login.jsp?at=long-encrypted-user-id Here's what I have till now: server { server_name hostname; location / { proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://127.0.0.1:port/; } } This only replaces http://hostname by http://127.0.0.1:port in the background; Where I'm stuck is adding the ?at=long-encrypted-user-id to the URLs. Can somebody help?

  • Why does Ubuntu 11.10 hang frequenty?

    - by ParveenArora
    I've been using Ubuntu from a long time and recently I have shifted to its newest version 11.10. Its interface is nice but my touch-pad hangs frequently in short intervals of time. When that happens, no key or key combination works. The only option is to restart or logout my laptop. I am using a Dell Inspiron N4010. I have tried a lot to solve this problem but haven't found any satisfactory help till now. Most of my friends who are using Ubuntu 11.10 reported the same to me, seems like it's a bug. How can I get out of this problem?

  • Minidump folder cannot be found

    - by Saxtus
    Although I have enabled the creation of minidump files in my system, it appears that either Windows doesn't create them where the Startup and recovery dialog points to (%SystemRoot%\Minidump) or at least I can't find them. Even the Minidump folder under Windows directory is missing and I had numerous BSODs till now. I've searched all my HDs for mini*.dmp files only to find some old ones in a backup folder from my Vista x86 installation, before I install Windows 7 x64. Any thoughts of why this is happening and how to fix it? Pre-thanx!

  • Second partition with Windows 7 unmountable

    - by Florian Pilz
    I'm using GRUB2 to dualboot Ubuntu and Windows 7. I installed Windows 7 some days ago and rewrote GRUB2 to cope with the dualboot. Everything went fine till yesterday - I could boot into both OS. Since this morning my laptop restarts every time I choose Windows 7 from the menu. Ubuntu is still working. As I tried to mount the partition with Windows 7 on Ubuntu it gave me return code 2, so this isn't working as well. I tried to reinstall GRUB2 to the MBR but it didn't help. I also tried to repair Windows 7 boot with it's install DVD, while trying so it showed me the following error: "Status: 0xc000000f Info: Boot selection failed because a required device is inaccessible."

  • looking for a clean way of how to bring down a ftp server for maintenance

    - by harald
    hello, i'm currently thinking of a clean way of how to bring an ftp server down for maintenance. i wonder, if anybody out there could give me some hints of how to solve this: i don't want to interrupt any current uploads, but want to block any new connects / uploads and wait, till uploads have finished, before taking down the ftp server is there a way of dynamically prevent user-logins and show a message eg.: "ftp currently down for maintenance" when a user tries to log in? are my thoughts on this very uncommon or how do others handle this -- i feel, that just halting ftp server and killing any current uploads is not the right way for this ... i use proftpd (with SQL backend) btw, maybe there are some specific solutions for this -- or are there any generic tools to achieve this? many thanks!

  • Linux: How to delay hddtemp service start at boot until all hdd are visible?

    - by Atis
    I live in a hot and humid environment, therefore I monitor the hdd temperature using hddtemp and gkrellm. There is an LSI9211 8i sata/sas controller in my computer. I have drives connected to both my motherboard and the LSI. hddtemp monitors only the drives directly connected to my motherboard after booting the system, therefore gkrellm displays the temperature of those drvies only. Logging in and restarting hddtemp before starting gkrellm fixes my issue, i.e. drives connected to the LSI controller are also visible. It seems that the drives connected to the LSI controller become visible only after hddtemp is started in the boot sequence. I think delaying it would help. How can I delay the starting of hddtemp till all drives are visible? I prefer a way to check if drives are visible to the delay of a specific amount of seconds.

  • How to fix wrong icons of the files in Windows XP SP3

    - by Angel_Kitsa
    Hi everybody, Recently I deleted some folders from *C:\Windows* directory with file names like this: $some_name_Uninstall$, which are the files of the patches, which were installed on the OS. It seems like my office placed the icons in some of those folders and now all xls and doc files have no icon. (I mean no Office icon) I couldn't find a solution for this till now. Please advice if someone had such problem and/or knows the solution. p.s. I have 7 years experience with Windows XP, so please don't ask me to do simple things like associate with files again or something like that. I tried a lot of things. Uninstall and install is not a way out. Thanks for any information!

  • What is the best package repository for Debian ?

    - by Dan Sosedoff
    Hello everybody I have a question regarding packages repository in Debian (Lenny). A new server at rackspace cloud service comes with nothing (plain system) so i had to upgrade system and install all necessary packages by myself. But the problem is that default repositories does not provide newer versions of software i need (PHP is 5.2.6, comparing to 5.2.13). In CentOS i used to get all new packages from third-party sources, which works really well till now. I have talked to guys from rackspace about it and looks like they cant provide anything except kernel headers. And i dont really want to build from source. So, whats the way to get newer software ? Any good third party sources? Thanks.

    Hi all, i'm trying to enable jboss to uses ssl protocol using a previously generated certificate from verisign, i imported both certificate, server certificate and ca certificate into the keytore file, and i configured the server.xml to use that keystore and activate ssl protocol, then when i run the jboss, I got this error "certificate or key corresponds to the SSL cipher suites which are enabled" Question, reading some post on internet, i found that every example was made it generating a Certificate Request, it stricly necesary to do that if i already have the server certificate and that CSR has to be imported into the keystore as well ? at this point i'm very confused about this issue, i tried almost every solutions posted in several forums but till now i haven't any luck !! can you give me some tips in order to solve this problem. thanks in advance this are my keystore file: Keystore type: jks Keystore provider: SUN Your keystore contains 2 entries j2ee, Dec 29, 2009, trustedCertEntry, Certificate fingerprint (MD5): 69:CC:2D:2A:2D:EF:C4:DB:A2:26:35:57:06:29:7D:4C ugent, Dec 29, 2009, trustedCertEntry, Certificate fingerprint (MD5): AC:D8:0E:A2:7B:B7:2C:E7:00:DC:22:72:4A:5F:1E:92 and my server.xml configuration:

  • best practice with memcache/php - multi memcache nodes

    - by user62835
    So I am working on a web app - that has to be built for scalability. It stores frequent MySQL querys into the cache. I have pretty much everything built and ready to go - but I am concerned on best practices on handling where to cache the data. I've talked to a few people and one of them suggested to split each key/value across all the memcache nodes. Meaning if i store the example: 'somekey','this is the value' it will be split across lets say 3 memcache servers. Is that a better way? or is memcache more built on a 1 to 1 relationship?. For example. store value on server A till it faults out - go to server B and store there. that is my current understanding from the research I have done and past experience working with memcache. Could someone please point me in the right direction in this and let me know which way is best or if I completely have this mixxed up. Thanks

  • 403 in Response to OPTIONS when updating working copy having full access

    - by user23419
    There is an SVN repository (single repository) http://example.net/svn The repository contains several projects (directories): http://example.net/svn/Project1 http://example.net/svn/Project2 User has full access to Project1 directory and has no access neither to root nor to Project2. Everything works fine for a while: user checks out http://example.net/svn/Project1, commits and updates it successfully. But sometimes trying to update leads to the following error: Command: Update Error: Server sent unexpected return value (403 Forbidden) in response to OPTIONS Error: request for 'http://example.net/svn' Finished! Why does TortoiseSVN request something in the root??? I have noticed that this happens after somebody else committed copy or move operation. Checking out http://example.net/svn/Project1 helps till next time... The main question: How to set up access rights for user to avoid these errors? Note, it's not an option to grant user any read or write access right on the root directory for security reasons.
