  • 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?

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!
