How to debug a non consistent null reference in C# ?

I have an Animal base class that I use in some simulation programs. In this case there may be up to 500 Animals in a run. Each run is set up to have each Animal do something each "time step". So I just loop through the list of animals , call DoTimeStep on each one until all the time steps are done for the run. Each Animal class ha...

Best VM for Delphi development with parallel port

I see that a number of people are doing S/W development (not just Delphi) using a virtual machine to host the IDE and all required files. I've used Microsoft Virtual PC to debug issues with my Applications on various OS's but with little access 'outside' the VM. My applications use USB, serial and - crucially - direct I/O writes to hardw...

Will I be able to successfully run this Ubuntu (linux) setup in Virtualbox?

Have 4 DVI output. Seems I hopefully will have driver support on this. Details are sketchy online about supporting 4 outputs, but seems possible. My question is from the Linux group and Virtualbox pros.... Will the seamless method of VirtualBox allow me to use all 3 of my monitors for multiscreen. I'd like to stick with Ubuntu and run ...

Opening a vpc image with vmware?

I have found articles saying this is possible, but what are the issues? Is it 'always' straightforward as shutting down your vpc and then opening it with vmware? From this link which is nearly 3 years old it says you can but you have to copy some windows files into the vpc before shutting it down, is that still valid? Update 1 Found t...

Software optimization for virtual machines

When you know that your software (not a driver, not part of the os, just an application) will run mostly in a virtualized environment are there strategies to optimize your code and/or compiler settings? Or any guides for what you should and shouldn't do? This is not about a 0.0x% performance gain but maybe, just maybe there are simple t...

.net: virtual network shares that pull their content from databases or other sources

I'd like to expose data that can come from different sources (ie. a database, or various other folders locations) and make it available as a virtual network folder so that users could access the data, and also write data into this virtual folder structure, with a listener translating the action into what should be done with the file behi...

VM Additions for ubuntu 8.10?

I know that VPC does not officially support Linux, but I was wondering if there are any ways to get things similar to the VM additions so that I can get: 1) A higher screen resoultion than 800x600 2) Faster graphics, no jerkey movements 3) Drag and Drop support Number 3 really isn't that important but it would be nice. ...

Are there any benefits to developing Java in a virtual machine?

I'm coming from the .Net camp where virtualization was much more prevalent do to the need to run on server software and system-wide entities such as the GAC. Now that I'm doing Java development, does it make sense to continue to employ virtualization? We were using VirtualPC which, IMO, wasn't the greatest offering. If we were to move...

related to port forwarding in VirtualBox Host ->Guest

I have WindowsXP as GuestOS inside VirtualBox running on Ubuntu 8.10. I am able to use Netmeeting inside WindowsXP (Guest) and connect to other machines in the intranet. Netmeeting listens to the ports 1503 and 1720 (among other ports). Now I would like to know how I can connect to the Netmeeting which is inside VirtualBox from a machi...

VMware Server 2 on Windows 2008 Server Core

I have an older server (retired database box in fact) that doesn't fit the requirements for VMware ESX/ESXi or Microsoft's Hyper-V but runs VMware Server 2 just fine. The host OS is currently Windows 2003 Standard. While it does the job just fine, I could hope for something a bit more "svelte" out of the box. Thus Windows 2008 Server Cor...

How do you use completely free software to create ovf files for VMware ESXi?

Ok, so let's say that I want to try virtualization in my environment. I want to use ESXi to do that because it is free. I can use the install disk and setup a box to run the ESXi Host. I'm not sure if the VMware Infrastructure Client is free for one thing. You can use it to attach an ovf file (a packaged VM). The problem I had is creati...

Hello Sun's virtualbox windows binaries are under 'non-commercial' license so can't be used in any company. But source code is GPL. Is it any resource on the network that has a virtualbox compiled binaries for windows? Added a bounty to see if I can get a little more feedback. ...

KVM, Xen comparison

I have the following comparison questions of KVM, and Xen: Security (how different are KVM and Xen here?) Speed(I'm a long time user of VMWare Workstation but there I'd think the loss is around 50 % to the native speed, this is IMHO too much) Stability (do Xen and KVM differ here much?) Maintainability (how difficult or easy is ot to s...

Wpf Datagrid Virtualization Issue when setting cell colors

I'm working with the wpf toolkit datagrid and have a column that is populated with toggle buttons. Using the below style I change the background color if the toggle button is selected and also on mouse over. Unfortunately if I have virtualization enable, when I make a select of a toggle button in a cell and scroll down in the grid I wi...

WSS log files growing out of control

I'm using Microsoft's WSSv3 demo Virtual PC demo and the VHD is growing out of control. Using Folder Size I was able to trace it down to the WSS log files. Today I have two log files that grew to excessive size. 1) 2.5GB within 30 minutes and then 2) 2.1GB within 2 hours I'm trying to review the content with LTFViewer, but the files ...

Which Linux distro is best for running in a virtual machine, for programming research?

I'd like to learn LAMP development for my own personal edification. I tried setting up Ubuntu 8.10 "Hardy Heron" in Microsoft VPC, but I can't get the video to work above 800x600. Played with xorg.conf a million times but no joy. Can anyone recommend a good distro to work with that plays well with VPC? Any guidance on getting started...

Hardware requirements for a Virtual Server

We have decided to go with a virtualization solution for a few of our development servers. I have an idea of what the hardware specs would be like if we bought separate physical servers, but I have no idea how to consolidate that information into the specification for a generalized virtual server. I know intuitively that the specs are n...
