DX11 Getting notified when fullscreen mode is interrupted

Recommended Posts

ehmdjii    238

hi, i use DX11 to bring my game into an exclusive fullscreen mode.

 

i want to handle the events, when the fullscreen mode is interrupted by the OS. like when alt+tab is pressed, or ctrl+alt+del.

 

is there an event on the Window or the WindowHandle where i can subscribe to?

In your windows message loop, you can listen for events of type "WM_ACTIVATE" and "wParam == WA_INACTIVE".

See the msn documentation for details.

 

This will solve only part of your problem though, because it won't work for all the possible cases:

  • For alt-tab and windows-key, you will receive a WM_ACTIVATE event.
  • For ctrl+alt+del and lock screen (windows-key + L) you will not receive an event.

 

So, if you really want to catch all possible cases where your fullscreen mode is interrupted, you have to do what Medo3337 pointed out:

In regular time intervals, actively check the state of your window and/or your display device. This might seem inconvenient, but I have found no better way.

      Hi! I am trying to implement simple SSAO postprocess. The main source of my knowledge on this topic is that awesome tutorial.
      But unfortunately something doesn't work... And after a few long hours I need some help. Here is my hlsl shader:
      float3 randVec = _noise * 2.0f - 1.0f; // noise: vec: {[0;1], [0;1], 0} float3 tangent = normalize(randVec - normalVS * dot(randVec, normalVS)); float3 bitangent = cross(tangent, normalVS); float3x3 TBN = float3x3(tangent, bitangent, normalVS); float occlusion = 0.0; for (int i = 0; i < kernelSize; ++i) { float3 samplePos = samples[i].xyz; // samples: {[-1;1], [-1;1], [0;1]} samplePos = mul(samplePos, TBN); samplePos = positionVS.xyz + samplePos * ssaoRadius; float4 offset = float4(samplePos, 1.0f); offset = mul(offset, projectionMatrix); offset.xy /= offset.w; offset.y = -offset.y; offset.xy = offset.xy * 0.5f + 0.5f; float sampleDepth = tex_4.Sample(textureSampler, offset.xy).a; sampleDepth = vsPosFromDepth(sampleDepth, input.uv).z; const float threshold = 0.025f; float rangeCheck = abs(positionVS.z - sampleDepth) < ssaoRadius ? 1.0 : 0.0; occlusion += (sampleDepth <= samplePos.z + threshold ? 1.0 : 0.0) * rangeCheck; } occlusion = saturate(1 - (occlusion / kernelSize)); And current result: http://imgur.com/UX2X1fc
      I will really appreciate for any advice!

       I'm trying to code Rayleigh part of Nishita's model (Display Method of the Sky Color Taking into Account Multiple Scattering). I get black screen no colors. Can anyone find the issue for me?

      I made my obj parser
      and It also calculate tagent space for normalmap.
      it seems calculation is wrong..
      any good suggestion for this?
      I can't upload my pics so I link my question.
      https://gamedev.stackexchange.com/questions/147199/how-to-debug-calculating-tangent-space
      and I uploaded my code here

      Hi guys, 

      I dont know if this is the right section, but I did not know where to post this. 
      I am implementing a day night cycle on my game engine and I was wondering if there was a nice way to interpolate properly between warm colors, such as orange (sunset) and dark blue (night) color. I am using HSL format.
      Thank  you.

      I am aiming to learn Windows Forms with the purpose of creating some game-related tools, but since I know absolutely nothing about Windows Forms yet, I wonder:
      Is it possible to render a Direct3D 11 viewport inside a Windows Form Application? I see a lot of game editors that have a region of the window reserved for displaying and manipulating a 3D or 2D scene. That's what I am aiming for.
      Otherwise, would you suggest another library to create a GUI for game-related tools?
       
      EDIT:
      I've found a tutorial here in gamedev that shows a solution:
      Though it's for D3D9, I'm not sure if it would work for D3D11?
