• How does the setup bootstrapper detect if prerequisites are installed?

  - by Marek

  Trying to solve this problem. I would like to learn how the bootstrapper detects if prerequisites (specifically .NET 3.5) are installed. According to this reference, a way to detect if .NET is installed is to check the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5 Using process monitor, I have inspected registry queries done by the bootstrapper (setup.exe) and it did not show any access to this registry key. Does anybody know how the bootstrapper determines whether the prerequisites are installed on the target system?

• How can we detect hotkeys registered by other apps?

  - by worlds-apart89

  Is it possible to detect all the hotkeys registered by the OS as well as software applications currently running? Any native or managed approach on the Windows platform? I know that the RegisterHotKey function returns false if the hotkey is already registered, but what I am looking for is an approach, method, etc. that will give me a list of registered hotkeys. Looping all possible combinations with RegisterHotKey does not sound like a good idea. Anything more efficient?

• Flex PopUpManager: How can I detect the existence of a modal popup?

  - by Glenn

  My Flex 3 application has some modal dialogs displayed via the PopUpManager, but there are times when I'd like other view components to know there is popup displayed. The PopUpManager doesn't have any method for actually checking the existence of popups. Is there any other way to detect this in flash/flex without writing my own global manager? (also systemManager.popUpChildren.numChildren == 0 even when there's a modal popup) Cheers.

• How can I detect device orientation going back and forth through tabs and views?

  - by JoshD

  My application goes back and forth between Portrait and Landscape. I have all of my content(labels, uiimageviews, uilabels) lined up to relocate for both orientations. However, the only change when the device is actually rotated. When I cycle between tabs after it has been rotated it just shows up autosized and not the way I have it setup when the user rotates it. How can I detect the orientation of the device and display the view to reflect the orientation when the taps different tabs?

• How to detect which Windows account is running a .net application?

  - by Bryan

  Hi, I'm writing a sharepoint web part. It writes logs into a file (by using StreamWriter). However, logs are written only for users whose accounts are administrators on the server hosting the web part. I want to detect which account (probably not by using SPUser) is executing web part's code, so that I can have logs generated for less privileged users. Is that possible? Thanks

• How to detect which Space the user is on in Mac OS X Leopard?

  - by georgebrock

  Mac OS X Leopard has a virtual desktop implementation called Spaces. I want to programatically detect which space the user is currently on. Cocoa is preferable but AppleScript is acceptable if there's no other way. I've seen a couple of AppleScript implementations, but the techniques they used seemed a bit too hacky to use in production code (one relied on causing and error and then parsing the error message to get the current space, the other interrogated the Spaces menu GUI)

Unfortunately, if the camera is already in use by another application, say a desktop application on user's system, the browser is crashed.

• Is there a way to detect when a WSS default.aspx page is updated?

  - by Alan

  That is detect when the user makes web part changes and selects to exit editing the page. I want to be able to capture a page event, then create a SharePoint task to instruct a user to translate that page to another language (note that MOSS and variations is not an option because the client wants to use the free version of SharePoint). So the customer wants essentially the same WSS site in multiple languages.
