• How to prevent shortcuts from firing when form is not active

  - by Erick Sasse

  I open forms inside tabs of a page control. These forms may contain actions with shortcuts. And I want these shortcuts to be fired only when the tab that contain this form is active. I tried to override form's IsShortCut but it's not called. Form's OnShortCut is not called either. I would like to avoid putting code on each action to check this. I'm using Delphi 2010.

• 'Unlimited' free trial of Windows Server 2008 by deleting and reinstalling VM? [closed]

  - by MrVimes

  I am using Virtual Machine software (VirtualBox) to learn Windows Server 2008 R2 Network Infrastructure (70-642). Trouble is - I'm learning at an extremely slow pace and so the trial periods of my virtual machines are close to running out. If I delete the VMs then install WS2008R2 from scratch on new VMs is that violating the acceptable use policy of Microsoft? I am aware that I can extend the trial, but it seems I can only do that by 10 days at a time. Also I think having to re-install from scratch is a good way to reinforce the knowledge.

• JNA problem with char** (in dll)

  - by underline

  Hi, ok it is 'easy' to make jna wrapper solution for mapping exported functions within dll using jna: long f1(int x), just int long f2(char* y), just char[] but how to deal with long f3(char** z) ? I need f3's result(long) as well as z value on java side. Please don't say cpp code should be rewritten to avoid this:-)

• How to modify existing keyboard layout (RU, kbdru.dll)?

  - by Anton

  There's a program I'm thinking of using called Punto Switcher that detects a language I'm typing in and switching entire word between Russian and English. The problem I have with this setup is that even though most of Russian letters "correspond" to English letters, Russian keys are scattered all over the keyboard and I don't feel like learning them all as I type in English mostly. Now, the program is very specific about me using RU, kbdru.dll file, not any other and if I use a custom keyboard under Russian, it doesn't recognize what I type so I think I should change the default RU keyboard. I created my custom keyboard using Microsoft's tool and I need to modify original one. I think it will take more than just replacing a file. Help?

• Setting up a transparent proxy with only one box.

  - by Scott Chamberlain

  I am playing around with transparent proxies, unfortunately I do not have two machines to test it out with. The current way I am doing things is the program makes a request to a computer on port 80, I use iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy so I want to do something like iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong, I am learning after all and constructive criticism is definitely appreciated. The machine I am using is pretty low end so I would like not not have to create a VM with a second box unless absolutely necessary.

• Is there any analog of TCPvcon which allows to close TCP connection on remote machine?

  - by Miollnyr

  Hi, I started to use SysInternals suite, and it is great. But I wonder, whether there is any analog of TCPvcon, which allows to logon to remote machine, like psexec does, and then get list of TCP connections from there (similar to pslist functionality), and then to close some of connections (similar to pskill functionality). I am speaking about windows console tools and I would like to avoid installing something on remote machine is this is possible.

• C: performance of assignments, binary operations, et cetera...

  - by Shinka

  I've heard many things about performance in C; casting is slow compared to normal assignments, functional call is slow, binary operation are much faster than normal operations, et cetera... I'm sure some of those things are specific to the architecture, and compiler optimization might make a huge difference, but I would like to see a chart to get a general idea what I should do and what I should avoid to write high-performance programs. Is there such a chart (or a website, a book, anything) ?

• In Bash, how do you access command line arguments inside a function?

  - by DonGar

  I'm attempting to write a function in bash that will access the scripts command line arguments, but they are replaced with the positional arguments to the function. Is there any way for the function to access the command line arguments if they aren't passed in explicitly? # Demo function function stuff { echo $0 $* } # Echo's the name of the script, but no command line arguments stuff # Echo's everything I want, but trying to avoid stuff $*

• How do I add an Approver to SharePoint 2010?

  - by CompGeekess

  I am still new to SharePoint and am learning so much, but have came in to a few hic-ups and here is one. I want to add an approver to SharePoint 2010 who has FULL CONTROL. My manager requested that I find out where the approval request are going and redirect them to him. (I have no idea where or how to find this out). Is this possible to do on the Central Administration or must I go into each site/subsite and set him to be the approver this way? Googled and the site was showing me how to approve workflows or how to create approvals, my other resources didn't give much help either. So far I had gone into a few individual sites and set my manager and I up as approvers with full control, but am uncertain if this is the correct procedure or if there is a better way to do this. For example, have the lower levels inherit from the higher level - set security at the highest level and cascade to the child levels. Thank You.

• Why use an event cache with epoll_wait?

  - by user1827356

  Question: epoll man page has some pointers when using epoll with an 'event cache'. But, why would you need to maintain an event cahce at all - Isn't this the same as what epoll is supposed to be doing? Is it to avoid making multiple epoll_wait calls which might be slower than managing the events in user space? Is it to implement a custom 'priority' scheme over the cached events? Background: I'm trying to understand the strengths/shortcomings of epoll and its applicability to different situations

• Is it bad to throw exceptions to trigger server errors, eg. 404 Page Not Found?

  - by Pheter

  I am working on a PHP framework and am currently designing error handling. Based on what I have read on SO, I should only use exceptions for, well, exceptional situations. Therefore throwing an exception when an incorrect password is entered is wrong. Should I avoid using exceptions when I want to trigger a server error? If so, should I write my own error handling class?

• Per-character-set font size in Firefox not working?

  - by Coderer

  Firefox has a setting (Preferences - Content - Fonts & Colors - Advanced) that is supposed to let you set font preferences for different character sets. I've tried setting larger minimum font sizes for some non-Western character sets (I'm still learning, and have to see extra detail to tell them apart!) and nothing seems to happen. For example, if there's Hangul on a page (like this one), it will show in the same size as the Latin characters around it, even if I set "minimum font size" to 24. Am I misunderstanding how that setting is supposed to work, or does it just not do anything? Is there any other way to blow up only non-Western characters while leaving the letters I know how to read intact?

• Blackberry (Java) - Setting scrolling be not focused on objects on the screen

  - by paullb

  I have a mainscreen which currently scrolls (and I have the arrows on the right) but the scrolling seems to be focused on the ButtonField objects that I have on the page. Is there any way to set the scrolling to be non-focused scrolling (moving a few pixels each time). Is there a way to set this? Other ideas I have had (which sound hacky so I want to avoid): - Placing NullFields around to scroll - Manually listening to the trackwheelRoll event and moving appropriately
