• Setting a mapped drive in Virtual hosts causes apache to not start

  - by darksoulsong

  I´m trying to set a virtual host on my windows 7 machine. The folder I want to point to is located on a centOS machine and the folder path is Z:\Websites\Online\MyClient\Site. But something strange happens when I set the document root like this: DocumentRoot "Z:\Websites\Online\MyClient\Site" Apache do not restarts after that. When I take a look at the log, there is an error pointing to that line, where I added the path to the folder: Syntax error on line 48 of C:/Program Files/Zend/Apache2/conf/extra/httpd-vhosts.conf: DocumentRoot must be a directory. There must be a way to make it work like this, by setting an Apache Installation on a machine and pointing it to a folder located on another computer, right? My hosts file is set like this: 172.17.10.1\Data\Websites\Online\MyClient\Site MyClient.local ANY HELP would be VERY appreciated.

• How to pass objects to functions in C++?

  - by Rakesh K

  I am new to C++ programming, but I have experience in Java. I need guidance on how to pass objects to functions in C++. Do I need to pass pointers, references, or non-pointer and non-reference values? I remember in Java there are no such issues since we pass just the variable that holds reference to the objects. It would be great if you could also explain where to use each of those options.

• ESXI 4.0 Slow response in opening anything accross the network on a Virtual Server running Win2008

  - by user40944

  Hi I recently installed a HP ML350G6 Server with Windows Small Business Server 200864bit, Exchange 2007. The server was running fantastically and we transferred all user data onto the new server and no problems for 2 weeks! We then installed SQL2008 and transferred the accounts package onto the server and this is where the problems started. Users are now complaining to open a work document can take 2 minutes and the same with regard to anything else. The server itself seems fine, the virtual server seems fine! No disk performance problems (doesn't go above 50% unless i really copy lots of things), no memory, (12Gb only using 7Gb) cpu (usage is low average about 15%) etc on both the VM and in Windows Task manager. I have made sure disk caching is enabled on the raid controller (which made no difference). Network cards are running 1Gb and plugged into HP GB switch. Please help!

• Enable clipboard functions in swf generated by pdf2swf.

  - by user515

  I am using pdf2swf (http://www.swftools.org/) to convert PDF's to .swf. I have written a flex application that loads the swf generated by pdf2swf. I want to enable select , copy and paste functions on the loaded swf. Is there a way to do this. Please note I am able to extract the text from the loaded swf using textSnapshot, which means the pdf2swf does not convert the text to shapes.

• Hyper-V R2 as a VM on another virtual OS

  - by Tim

  I am trying to perform Microsoft Platform testing for a vendor application. The problem I have is that it requires the test be done on Windows Server 2008 as a VM on Hyper-V R2. Currently, I have access to a virtual server with just Hyper-V and also have access to an ESXi server. The crazy idea (which may just show how little I know about how virtualization technology works) is to install Hyper-V R2 as a VM onto one of these other servers. Then create a VM for Windows Server 2008 on this Hyper-V R2 VM. I can not just upgrade the current Hyper-V server as the VMs currently running would need to be taken off-line and are system critical (and I don't have rights to perform this upgrade). Has anyone tried this? Will this even work?

• Adding procedural C openGL functions to an iPhone project

  - by user309595

  I want to add a few drawing functions to an iPhone project for drawing things. Something like drawTile(x,y,len,wid); which would call openGL to draw a box somewhere. I should just be able to write a procedural C file to do this but the openGL libraries are objective C and I'm getting weird errors. Do I have to make a class for all of my drawing commands and call class methods?

• How do I assign functions in a dictionary?

  - by Ziv

  hi, I'm having a problem with a simple program I wrote, I want to perform a certain function according to the users input. I've already used a dictionary as a replacement for a switch to do assignment but when I try to assign functions to the dictionary it doesn't execute them... The code: def PrintValuesArea(): ## do this def PrintValuesLength(): ## do that def PrintValuesTime(): ## do third PrintTables={"a":PrintValuesArea,"l":PrintValuesLength,"t":PrintValuesTime} PrintTables.get(ans.lower()) ## ans is the user input what did I do wrong? It looks the same as all the examples I've seen....

• Using functions and environments

  - by Eduardo Leoni

  Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

• JavaScript Self Executing Functions - What's the Difference?

  - by modernzombie

  I am very familiar with self executing functions from working with jQuery. (function($) { /* do stuff */ })(jQuery); Today I was reading the backbone.js source and noticed that they do this: (function() { /* do stuff */ }).call(this); Is this achieving the same thing? Would the following 2 lines of code do the same thing? (function($) { /* do stuff */ })(jQuery); (function($) { /* do stuff */ }).call(jQuery);

I have Virtual PC installed so I can use Microsoft's IE compatibility images - are there any time-limited images that I can use with Virtual PC so I can check out IIS 7?

• How create a virtual network for practice?

  - by light

  I need to organize a virtual network for practice with Windows Server 2008 and several workstations with Windows OS. To make it all I only have a laptop with Dual-Core 2.10Ghz, 3 GB RAM, 50 GB free space and Windows 7 on it. Also I have external USB 3.0 hard-drive with 250GB free space and flash disk with 8GB space. What can you suggest? Because I have limited resources, I think to install ESXi 5.1 on the main disk of my laptop as second OS, with installed Windows 7. I have no idea will it work or not, but after that I want to try to create hosts using availible space on external hard-drive. Is it possible?

• Debian virtual server hangs on reboot, need help debugging

  - by BubuIIC

  I'm admin of a Debian 6 virtual server. I've been trying to diagnose this problem for a while but haven't gotten anything. The server hangs every time I want to reboot it. All services seem to be shutting down, I lose ssh connection. Then nothing. I have to restart it through the hoster's web-interface, which just gives me the options "Normal Boot" and "Rescue System". Normal boot then brings the server back to life. Possibly (probably?) related, the server does not boot into a newer kernel version, it's running 2.6.18 right now, but installed is actually 2.6.32. I don't know whether it hangs on shutdown or on startup, but booting through the web-interface works (except the kernel part). Am I missing something obvious? Where should I start looking? I have no idea how to diagnose the problem.

• referencing desired objects in namespaced functions

  - by RyOnLife

  I'm having trouble referencing the desired object when I've namespaced functions. No problems here: obj.test = function() { // this == obj } But I'm getting tripped up when I namespace: obj.namespace.test = function() { // this == namespace } In the latter example, I know this references namespace, but I want to reference obj. How can I do it?
