Is is possible to control the brightness of the screen on the WP7? The app I am making would be so much better if the user could change the brightness of the screen without having the leave the app.
No, this isn't a "flashlight" :)
It is not possible to control this programatically with the current SDK.
The user has exclusive control over the brightness setting.

I am trying to develop a MacOS application using Xcode and Cocoa. My intent is to create an overlay on the user's screen that is mostly transparent, and does not register input. For example, an application like f.lux tints the colour of your entire screen like a global overlay, but you can still click on-screen items, as mouse clicks go right through (assuming that it's an overlay). How can I get started with achieving a similar overlay/widget?
So I have next problem:
I have two monitors and do video translation from web camera on one of them(secondary). I do it in full screen mode using
put_FullScreenMode().
It works fine but when I click any mouse button on area of primary monitor, window with video translation wrap into just window mode.
How can I save full screen mode working with primary monitor?
At the first, I move my video to the left (on secondary monito from primary) and use full screen mode.
if(monitors.GetCount() > 1)
gx.pVW->put_Left(primaryRect.right);
gx.pVW->put_FullScreenMode(OATRUE);
gx.pVW->put_Visible(OATRUE);
Thank you for your time.
[Much] older applications took advantage of FullScreenMode since API supplied a specific "full screen renderer" filter which efficiently took care of full screen presentation. Since then video adapters found their way into stretching of presented video and full screen mode become unnecessary. Windowed mode of video renderer (you are using) was also not a recommended mode compared to windowless any longer.
You would be better off using renderer in windowless mode right in your UI, in your window, form or dialog. Using borderless window hosting video renderer you can easily imitate full screen mode without actually change of display mode. Such window remains normal window and does not need to go back from full screen with another UI activity, e.g. such that happens on another monitor.
VMR filters themselves demonstrate the two ways of going fullscreen in their Filter Config property page:
Set Fullscreen does it the way you do and suffer from the mentioned issue. The other method does full screen mode using borderless window stretched to the extent of a monitor.

I'm working on an app where I need to change the brightness. However, I want the user to be aware of the relative brightness by seeing the built in brightness slider they're used to. Also- this designed to run only on laptops or tablets so the displays should support programmatic brightness.
*Note: This image was stolen from this post.
I was hoping it would automatically show up when I changed the brightness programmatically but no luck there. I tried doing so with WmiSetBrightness() and with PowerWriteACValueIndex() but neither of them showed the slider.
TL;DR I want to programmatically invoke the slider to show the user what the current brightness level is. Any ideas?
I have recently started on a project developing a window mobile/ce buisiness application. I have a ui design that uses a wizard to capture input data. To get the wizard started we open a windows form and maximize it. The form has one panel on it that is set to the size of the form. We pass a reference to the panel into the wizard controller as a container for the wizard user controls (each wizard step is a user control and the user control's size is set to that of the panel and thus the windows form. When viewed in a windows mobile emulator this works great the user control takes up the entire screen and the controls on the wizard step control are all visible on the screen with no vertical or horizontal scroll bars visible. When we load this onto one of the potential handheld devices the windows form doesn't fit exactly onto the screen as I would expect. There are both horizontal and vertical scroll bars and the controls aren't all visible. Does anyone have any hints and tips on getting around this problem? Is it possible to maximize a windows form in such a way that it exactly fills the screen on any mobile or ce device?
You need to check the screen resolution of your emulator and of your handheld device.
I suspect you are working on different screen resolutions.
If it's the case, then set the screen res for your emulator to match the screen res of your device. If for some reason this is not possible, just create your form to match the screen res of the device and try to fit all your UI in that limited space.
If you need to support many screen resolutions, you have 2 approaches:
1. Develop for the lowest res. This might look a bit ugly for higher res devices
2. Use anchors and control docking when defining your form layout.
Is there any way to set any of settings from "Settings menu" programmatically, from app?
For example change date-time, set screen brightness or change theme color, etc.
At the moment this functionality is not exposed by the API.
Only the user can control these features.
