• Win32 API prevent standby

  What is the Win32 api function that prevents the system from going into standby? Some programs use it, which is pretty annoying in my opinion. I know there's a couple of WM_SYSCOMMAND messages you can trap to prevent the screensaver from coming on..

• Prevent image cropping when making sprites from gif

  - by OSaad

  Hey guys I've tried several tools (imagemagic, gif2png, Nconverter) to extract frames to make sprites from a .gif image that i have. I get the .pngs just fine, but they'r not the same size, some are 50x65 some 43x65 some 50x70, Which really screws any attempts at a descent animation. So is there a way to prevent this cropping or programmatically add extra transparent space to smaller ones and make them all the same size? Thanks.

• Prevent subview from scrolling in a UIScrollView

  - by jbrennan

  I have a UIScrollView subclass with a certain subview I'd like to prevent from scrolling (while all the other subviews scroll as normal). The closest example to this I can think of is UITableView's "index strip" on the right side (look in the Contacts app to see an example). I am guessing this is a subview of the table (scrollview) but it does not move as the user scrolls. I can't seem to make my subview stay put! How can I accomplish this?

• Are you human? (or How to prevent spam)

  - by pek

  What mechanisms do you know that prevent your site from being abused by anonymous spammers. For example, let's say that I have a site where people can vote something. But I don't want someone to spam something all the way to the top. So I found (a) creating an account and only allowed to vote once and (b) CAPTCHA to decrease spam. What other methods do you know and how good do they work?

• Prevent change of hidden field

  - by er-v

  What if I have ChangePassword form with hidden ID field of the user. BadPerson knows id of GoodPerson. He opens Change Password form with FireBug, changes his Id to GoodPerson's Id, so password changes for GoodPerson. Of course I can create some server logic that will prevent this, but I think there should be some out of the box solution, wich throws if hidden field been changed, wich I don't know. Thank's in advance.

• Prevent deploying debug build with ClickOnce

  - by jomi

  Hi, I'm publishing a ClickOnce application with VS2008, but before every publish I have to switch to Release config manually. This is fine as far as I don't forget to switch. Is there a way to prevent deploying debug builds ? Is there some compiler directive like: #if DEBUG #if ClickOnce #error You cannot publish a debug build #endif #endif Or is there a way (without build scripts) to automatically switch to Release config before publishing ? (I've found some similar questions but didn't like the anwsers on them) Thanks

• Prevent automatic popToRootViewController on double-tap of UITabBarController

  - by NilObject

  The default behavior of a UITabBarController is to pop the contained UINavigationController to the root view controller when a particular tab is tapped a second time. I have a particular use case where I'm wanting this to not work automatically, and I'm having a hard time figuring out how to prevent this. Has anyone run into this, and if so, what did you do? Do I need to subclass UINavigationController and override popToRootViewController or is there a simpler way?

• Prevent windows from presenting any dialog on native code unhandled exception

  - by Lucas Meijer

  Our buildserver compiles and runs testsuites for many different c++ programs. From time to time the programs are buggy, and can crash. When they crash, Windows7 will always throw this modal dialog: Which has to be clicked away by a human being, causing the buildserver to sit idle. Is there a way to at a system level prevent this from happening? I know I can do it from within the process itself, but I'd love to be able to do it across the entire system.
