Stupid windows vista/7 failure to resume problem resolved!!!

For a while now I have not been able to use sleep or hibernate on my Windows Vista and then Windows 7 machine when I upgraded.

The behaviour was as follows.

1. Put the machine to sleep
2. Resume the machine, everything seems to start, but the display is black (not signal out of range)

I turned off the require password section to see if it was related to this and I could now see my desktop accept it was a zoomed in version of my desktop, zoomed in to the bottom right corner of the screen, but missing the windows bottom bar. Icons and windows that were overlapping that portion of the screen also did not appear.

moving the mouse around I found that I could make my mouse cursor appear on the screen. I could right click to obtain the context menu I selected Nvidia control panel and suddenly my desktop was back to normal.

After further investigation I found that although everything was fine on boot up. resuming from sleep appeared to enable a 1900*1600 generic pnp driver from dvi socket 2 and set this as the main display and set my monitor that was plugged in to dvi socket 1 as and extended desktop from socket 1. This mean that the real desktop was appearing on a phantom second monitor which at no point has existed. This second monitor did not appear in the drop down list from a standard boot, but would always appear after a sleep or hibernate. I have disabled this driver and now I can use sleep mode again!!!

After I fixed the problem I only found one other person who appears to have experienced this issue. I am sure we cannot be the only ones, so hopefully this post will help someone with the same annoying issue.

IE9 Intranet compatibility mode in Intranet websites

So you have written an HTML5 site on your local intranet with some lovely CCS3 and run it up in Firefox and you feel smug, all your HTML and CSS are perfectly formed, but you run it up in IE9 and all the CSS3 goodness has gone away leaving your lack luster IE7 version of your site.   Why is IE9 running in IE7 compatibility mode? IE9 has a hidden setting that forces it to run in compatibility mode when it encounters any intranet websites. Microsoft have detailed this behaviour in a Blog about what they call Smart compatibility mode . You can easily switch off the compatibility mode for specific machines using the internet tools mentioned in the article above, but most of the time developers do not have the luxury of applying corporate wide settings of this nature. Avoiding Smart compatibility with X-UA-Compatible Luckily there is a single line of HTML you can that you can use to override this behaviour: <meta http-equiv="X-UA-Compatible" content="IE=edge,c

User Interface Usability Checklist Part 2

So you made it through part 1 of the usability check list, how about part 2? 21. Poor Label Alignment If you have been through design 101 you have probably heard of the wonderful acronym for the basic principles of design, C.R.A.P. This of course stands for Contrast, Repetition, Alignment and Proximity. Proximity is very important when identifying which label belongs to which input. Each different form of alignment has its advantages and disadvantages. Left Alignment The label appearing on the left of a box is a common practice. This often helps with vertical space and keeping all of the elements of a form on a single page, which can be beneficial in aiding the user in form completion and making them aware of all of the possible options they can, or made need to provide information for. It does however have a few disadvantages. Long labels cause short label's input boxes to be far away from the end of the label, this damages that basic principle of proximity. In extreme

Procedural VS Object Oriented

What is the correct way to write code? If you have worked with PHP long enough you may well have come across the website  PHP The Right Way . This website is dedicated to helping developers learn the industry best practices. Interestingly another site appeared afterwards called  PHP The Wrong Way . In essence this website is a rebuttal to the many of the recommendations made in PHP The Right Way. With any sphere of learning it is important to keep an open mind, to listen and critically evaluate the received wisdom and determine if it is indeed wisdom or opinion built on shaky ground. There is one part of the argument I would like to focus on and this is the argument for and against " Always use object-oriented Programming ". While PHP The Right Way does not appear to explicitly state that you should always use an object oriented approach it is implicit from the examples and the recommendations to use design patterns. While there are programming approaches available othe
