What's to handle?
When you alt-tab from a full screen DirectX app, you have to reset the device and re-create all the resources that were in video memory. I've never really looked into it, but I read somewhere that a good thing to do would be to have it call the initialization procedure once the window is re-activated. *Shrug* |

The language itself isn't complicated, it's getting it to do what you want that's the puzzle. Here, Here.That, my friend, should be on a T-shirt, or in somones signature.  |

ok thanks, ill try it out when i come home  edit: it works, but now, if i alt-tab out of it, it directly goes back without alt-tabbing in it. this is my code: HRESULT hr;
hr=d3ddev->TestCooperativeLevel();
if (hr==D3DERR_DEVICELOST || hr==D3DERR_DEVICENOTRESET) enable_d3d(hwnd,hi); how could i make it wait until i alt-tab back in? |

D3DERR_DEVICELOST tells you that the device is lost, but it can't be resetted yet. So maybe do this; if(hr == D3DERR_DEVICELOST)
{
Sleep(100); //Wait a bit so we don't burn through cycles for no reason
}
else if(hr == D3DERR_DEVICENOTRESET)
{
m_pd3dDevice->Reset(&d3dpp);
} |

You can also use " WM_ACTIVATE", which I believe is called anytime a window gains or loses focus. |

well, i did try this: HRESULT hr;
hr=d3ddev->TestCooperativeLevel();
if (hr==D3DERR_DEVICENOTRESET) enable_d3d(hwnd,hi);
but it won't work. so i think i would try WM_ACTIVATE, ill edit if it works |

Alt-tab is a sizemove... case WM_SIZE:
switch(wParam){
case SIZE_MAXIMIZED:
m_bFullScreen=true;
break;
case SIZE_MINIMIZED:
m_ptrGame->GameEnd();
bIsMinimised=true;
break;
case SIZE_RESTORED:
if(bIsMinimised){
m_ptrGame->GameStart();
bIsMinimised=false;
}
//if(bSizeMoved){//after a resize, not during resizing
// FullOrWindowed();
// bSizeMoved=false;
//}
break;
}
break; This way changes the size also to fullscreen to windowed, but I think u'll get the idea  |

WM_SIZE works, thanks =) case WM_DESTROY:
PostQuitMessage (0);
break;
case WM_SIZE:
if (alt_tab_reset && wParam==SIZE_RESTORED)
enable_d3d(hwnd,pass);
break;
default:
return DefWindowProc (hwnd, message, wParam, lParam);
break;

Glad to be of service. All those little things make a programmers life difficult I'm programming a mini RTS in DX too, and it's getting the hell out of me. HLSL is cool too, but man, difficult |
