projector

问题 I've noticed a number of projectors have RS232 or USB ports that can be used for controlling the projector's functions, i.e. switching inputs and powering on and off. Does anyone know if there's an API around for controlling these functions programmatically? I'm using Java but especially with RS232 I'm guessing that's irrelevant as the protocol will be on a much lower level. If there's not a "standard" around (which I'm guessing there won't be) what would be the suggestion? At the moment I'm

问题 Is there any way to pass command line parameters to a Flash projector in Windows? I have another application (in this case, an installer) that will need to communicate to a Flash projector (the same way flashvars work). I wasn't able to find any information online (everything seems to be focused on using FSCommand parameters for executing future projectors, which doesn't help me with calling the original one)... 回答1: I'm fairly sure that standard Flash projectors can not do this. However,

问题 I am writing a small C# application to identify which type of display connect to pc A Monitor A TV screen A projector I try to do with Screen.AllScreens EnumDisplayDevices() but it does not help anything. When I use var mbs = new ManagementObjectSearcher("Select * From CIM_LogicalDevice"); ManagementObjectCollection mbsList = mbs.Get(); I can get device id: DISPLAY\OTMFB0E\4&9C24ACE&0&UID16843008 DISPLAY\DELD058\4&9C24ACE&0&UID50725632 But there is not any value which is used to identify

问题 I want to project the screen of my phone using a projector. So far, I've seen some who did it by installing an application on their PC to get a live view of the phone's screen and then connecting the PC to a projector. Now, I am wondering if I can connect my phone directly to the projector? Of course, that is assuming that I have a micro USB to VGA adapter. Is this possible? What application do I need to let my phone communicate to a projector? How do I do this? 回答1: There is no standard on

问题 I am trying to achieve the carousel and have got so far except not being able to show the image. The sample can be found here http://www.stevetaylor.me.uk/image-carousel-using-twitter-bootstrap-and-orchard-cms-projections. To replicate do the following: 1.Create a new content type a. Creatable b. Add Fields i. Field Name: Image; Type: Media Picker; ii. Field Name: Priority ; Numeric Field 2.Go to Admin>>Content. I would expect to see both the Image Url and Priority Value. However only see the

问题 I've had a bit of a search around, but couldn't find anything similar to what I was looking for. I'm interested in knowing how to display differing contents on secondary/tertiary monitors or projectors using C#. Basically, what I'm wanting to achieve is to have some form of presenter view (a lá Powerpoint) on one particular screen (the primary display), and the output on a secondary screen or projector. I've never really attempted to develop something with multiple display outputs, so any

问题 I'm working on a corporate project, creating a system that will be used for years. I've recently come across the "projection" media type in css, and I'm imagining potential benefits it could have for the users, giving presentations, etc, but I don't know if that's just in my imagination, or if there is a real world advantage here. So far all I'm aware of is that some versions of Opera use the media type in fullscreen mode. W3C media type entries: http://www.w3.org/TR/CSS2/media.html Does any

问题 I) Imagine that I created a projector get a list of content types ( Course in my case) and display it. The Create new course should satisfy 3 conditions: I would like to add new elements on this list using jQuery AJAX calls, including data validation on client and server side, and reusing the code of the data annotation at the Models. Before make the AJAX call, a pop-up dialog using jQuery UI appears, just like represented in the picture bellow: but I would like to add just a button on the
