I found out that you can actually zoom in on Power BI report in Power BI Desktop by pinching in or stretching out two fingers on laptop touchpad.
This quite useful feature that I would like to replicate on desktop PC without touchpad. Any idea if this is possible?
Thanks!
You cannot pinch to zoom with a standard, cheap mouse on a PC. This is standard with a Magic Mouse on a Mac, but not on Windows machines. On a PC, there's the "magnifier" thing in Windows 10, but I don't think anyone on Earth really likes it. Maybe an advanced mouse would help you. Different browsers have a zoom you can use. For example, in Chrome, hold the CTRL button & use your wheel up & down. Not exactly like "pinch to zoom" but that's about as close as you can get. Essentially, the answer to your question is no.

Using DXGI Desktop duplication with FreeSync/G-Sync monitor causes stuttering in full screen games. It happens in games which are in the "borderless fullscreen" mode by Windows 10 (you can check it e.g. when you change volume, you see the slider in the left top corner even in game).
I tried the sample desktop duplication and also tried to update the DuplicateOutput1 function. https://code.msdn.microsoft.com/windowsdesktop/Desktop-Duplication-Sample-da4c696a
Tested e.g. with Overwatch.
From Windows 10 1809 on Microsoft changed how the games run in fullscreen, so DDupl is almost unusable while playing since then.
Didn't anyone find a solution for this?
Thank you.
Since we have tablets with Windows 10 I have decided to use again Delphi XE7 and VCL to develop for this multitouch devices.
I have found ListView, ListBox and DBGrid seem not have a standard behavior with pan and scroll (just PanUp & PanDown, ScrollUp ScrollDown). DBGrid does not support touching panning. ListBox, seem doesn't control inertial panning like TListview... and ListView react erratically, sometimes "loose" pannings moving scrollbar but not items list.
Have someone tested this controls on Windows 8.1 or Windows 10 using a multitouch tablet ?. Just load components with, let me say 100 items and try to have a simple vertical smooth scroll / pan using fingers.
All together is kind frustrating, and I cannot focus in develop application which is my task.
Question is: Which is the right component or way to use panning (at least vertical panning / Scrolling) with touch screens and working smooth and without problems ? I thought this components should react to standard actions (like PanUp or PanDown) without need to implement the Gesture Manager and control one by one each touch on screen. I would like to receive your kind feedback. Thank You
Conclusion: Many thanks to all who have helped with their comments. My own conclusion is Delphi is not ready to be used as a RAD for touching screens. The touching implementation is poor and need too much work for very standard using. Should not be necessary invent the wheel again for a very common and standard controls. Actually there are more mobile device users, than desktop users. Perhaps Embarcadero should decide to pay attention to this matter, and give well finished tools wich meet the OS touch and feel controls.
Let me add the same in FM using TGrid works fine.
I found a small program a while back that let me disable the Aero Blur while keeping the transparency that came with the theme. The program worked on literally everything, except for the taskbar which still appears to blur everything that happens to be underneath it.
This curious behavior led me to experimenting with the DWM api, in C++. Sadly, this didn't really help me at all, since no matter what functions I'd use - like DwmEnableBlurBehindWindow() -, none of them would actually affect the taskbar in a way that I wanted them to. I even tried turning the alpha levels of the taskbar's owner "window" down, but sadly that didn't work either - It made the taskbar icons transparent too which is a no-no for me, and it didn't actually remove the blur it just made the effect weaker.
As it seems that my skills are not enough to accomplish this task, I'm asking you - how can I remove the Aero blur from the Windows 7 taskbar? (Possibly using C++)
Remove Transparency that will do, else go to
Personalize by right clicking on desktop.
There go to theme, personalize the theme,
and find transparency/opacity. if you want with no blur and enabled transparency make it 100%
else disable transparency.
this you can do using c++ by doing twiks with Registry.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM]
"Composition"=dword:00000000
"CompositionPolicy"=dword:00000000
"ColorizationColor"=dword:6b74b8fc
"ColorizationColorBalance"=dword:00000008
"ColorizationAfterglow"=dword:6b74b8fc
"ColorizationAfterglowBalance"=dword:0000002b
"ColorizationBlurBalance"=dword:00000031
"ColorizationGlassReflectionIntensity"=dword:00000032
"ColorizationOpaqueBlend"=dword:00000000
"EnableAeroPeek"=dword:00000001
"AlwaysHibernateThumbnails"=dword:00000000
this are the values for Windows 7,
if you will change here, you will get the result. it contains all things you need to change.
you may change values for this three
ColorizationBlurBalance, ColorizationGlassReflectionIntensity, ColorizationOpaqueBlend
I think that will do :)
I found a small program that will remove the blur.

What I need to do is create a program that overlays the whole screen and every 30 seconds the screen needs to flash black once.
the program just needs to be on top of everything, doesn't have to work over the top of games, but wouldn't say no if it did!
But i've got no idea where to start. Ideally the solution would be cross-platform for both windows and osx.
Does anybody have any ideas about where I should start or could whip up a quick demo?
OpenGL (you tagged it as such) will not help you with this.
Create a program, that overlays the whole screen,
The canonical way to do this is by creating a decorationless, borderless top level window with some stay-on-top property being set.
and every 30 seconds the screen needs to flash black once.
How do you define "flash back once"? You mean you want the display become visible for one single vertical retrace period or a given amount of time? Being the electronics tinkerer I am, honestly, I'd do this using a handfull of transistors, resistors and capacitors, blanking the analog VGA signal.
Anyway, if you want to do this using software, this is going to be hard work. If you'd do this using the aforementioned stay-on-top window, when you "flash" it away, all the programs with visible output would receive redraw events, which to process would take some time. In the best case scenario the system uses a compositing window manager which can practically immediately show the desktop. Without a compositor its going to be impossible to "flash" the screen.
Ideally the solution would be cross-platform for both windows and osx
A task like this can not be solved cross plattform. There's too much OS dependent work to do for this.
I presume this is for some kind of nerological or psychological experiment. I think doing this using some VGA intercepting circurity would be actually the easier, quicker to implement solution. I can help you with that. But I think there's another StackExchange better suited for this. Unfortunately digital display interfaces (DVI, HDMI and Display Port) use a complex line code scheme, which can not be blanked as easily as VGA, so you must have a computer capable of analog (=VGA) output and a display with a VGA input.
Tools like Fraps work with games based on OpenGL or DirectX but doesn't work with simple Windows 8 Metro style games like "Cut The Rope" or "Pirates Loves Daisies". Yes I know that "Cut The Rope" and "Pirates Loves Daisies" are using different technologies like JavaScript and HTML5 canvas but I'm really curious is it possible to build Fraps like tool for such games (some kind of canvas hack?). I would like to do 2 things:
1. Measure fps.
2. Capture screenshots.
I was reading articles about the whole Fraps concept and intercepting calls to DirectX but I'm not sure if its gonna work with Metro applications. Maybe I'm just wasting my time. I have 2 questions for you guys:
1. Do You think is it possible to build Fraps like tool that works with Metro style applications or games that are NOT using DirectX or OpenGL?
2. Does messing around with dxgi.dll (or other dll) could help somehow?
Thanks
Fraps is able to display the framerate because of hooks it has into DirectX. HTML apps do not provide access to this same information.
I've confirmed that the free program ScreenPresso (http://www.screenpresso.com/) can record Cut The Rope just fine.
Try Intel GPA (graphics performance analyzers)
http://software.intel.com/en-us/vcsource/tools/intel-gpa
Install it and then run the app.
There are a zillion options for graphs and stuff that I don't entirely understand (maybe it will be useful to you). If you want fps, just close the window; the program will continue running in the background.
There should be an icon in the lower right next to battery info and volume control. If you hover over it, it says your IP address. Right click on the icon for GPA and then select "Analyze Application" at the top.
A window will pop up with all the tile apps on the machine. Click on the app (don't double click) and click "run" in the bottom right.
The frame rate and resolution will be displayed in the upper left corner.
Tested and it works for Cut the Rope (I'm getting 58-60 fps). Hope this helps.
